Ya, fullRace makes some awesome manifolds but WOW they cost big bux! The key with these engines is airflow. On stock cams at about 700RWHP you'll start to run out of flow, swap in even mild HKS cams and watch power go WAY up - like 100RWHP up. IMO dump the OEM engine management and go AEM. Their setup is PnP with the OEM harness and there's lots of experience out there with this engine. lots of extra I/O too so you can get pretty trick with controlling things like boost and meth. Sadly it cannot control 16injectors so to run a true dual fuel system you have to get creative. If you go with someone else's system you can proably get some pretty good maps from the AEM guys. Oh as I recall DaveH simply ran 2 headgaskets for the longest time on his NA-T to get the compression down. You need not get expensive HKS gaskets etc. to get this done. The GE internals will take a great deal of abuse too - 500HP is nowhere near it's final capacity!

I have that Aussie article digitized and on my WEB server however right now the server isn't online. I will try to correct that in the near future so folks can checkout the article. One of the guys over there was kind enough to scan and send me a CD with the article not once but twice thanks to a teething puppy (lol). Interesting article for sure but some of the design solutions were probably less than optimal and not how folks here have done it.

Sounds pretty much like the setup I ran actually! Teflon line, Sureflo aggro pump with viton seals (I think), and a nozzle at the end - the M numbers even sound like the ones I used. They are for misting greenhouses and things and can be gotten in various materials. Guys use them to make snow too My pump was pulsed like an injector so while I had control it wasn't as fine as it might have been down low, there might have been a check valve too that I cannot recall. The electronic relay on mine was from an industrial A/C application and worked very well! Not bad if you have an extra injector output on your EMS like I did although truthfully I'd still have preferred a real injector. For low fluid I had a pressure switch on the pump setup such that when there was no pressure in the line the EMS received a signal telling it to maintain low boost. If the pump "fired" per the EMS but no pressure high signal was received boost pressure remained low. I liked it lots even with some silly shortcomings. You using Klotz lube in it by any chance? That's supposed to help keep the alcohol from being quite so harsh on materials but getting it well mixed can be troublesome especially if there's also water in there. P.S. Am in florida on business but sadly cannot stop by Right down the street in Melbourne but must fly early in the morning.

Unfortunately I've not got a bunch of stuff out there on a host I can link to but two of my dogs have been used for the local Shar-Pei rescue - where both were adopted from. I'm linking them so hopefully this thread won't get hammered too badly. This one is Toad. Quite the sweetheart but a stubborn butthead too. He's a complete ham for the camera so we've got tons of pics of him. (lol) This one is Scrappy-Do. Trouble in a puppy suit when she was younger. She's now quite the little priss. The pics of her as a puppy are pretty funny, I'll have to find a way to post some. We have two others. Kiesha who is terrified of the camera, she runs and so we have very few pics of her. (lol) She's a fawn Pei. The other is Micky, the youngest and fast a a greyhound I swear. She is also fawn and a female. I've had quite a few Shar-Pei over the years and I really like the breed. Boxers are also really kewl, we may yet get one of them but Pei keep following us home from the rescue - often as "fosters"! Thankfully the County only allows us to have 4 without a kennel license or we'd probably have even more! Oh yeah -> http://macspro.org/ for information on Pei

4G RWD? Wow, that's cool! I'd still want the displacement and toughness of a 2JZ but a RWD 4G is pretty neat. What I'd really like, and I hear it's been done, is an AWD Colt. Kewl motor and lots of parts for it. Be interested to see how this works out.

Ya' Mike they are indeed working on something it seems! My understanding is that the legislature was led to believe that this was primarily geared towards the really serious infractions rather than the wider net it actually cast. We'll see, I think it's safe to say that there are a few folks who will certainly be voted out by this. Some of the folks I've talked to about this are more angry than I am - that's saying something

What you using for nozzles and whatnot Scotty? I had an aggro pump and a mister for a greenhouse on mine. The Tupperware container I had worked well but yeah plastic is NOT the way to go long term. My dream was to use a second set of injectors and really do it right, that or a second fuel system with race gas

The funny thing is that when I drove the fastest car I've ever owned I never felt the need to race on the street. The entire time I drove that car, daily for awhile, I don't think I ever had a street race - maybe one roll-on on the highway that was short lived. I stepped on it once in awhile for sure but never for long and never in a manner that I felt could lead to someone getting hurt. Much of my WOT time was spent on the dyno or at the track when myself and other Supra owners would rent it for the day. There was nothing for me to prove with that car, it was damned fast and I knew it. I've never made it a habit to weave in and out of cars in traffic and generally I just sit in the left lane moving along unless I'm in someone's way. The day my car was trashed I was doing the speed limit and before the jerk pulled out I was even coasting - it didn't matter. Truly I wish the emphasis were on the folks who are really dangrous but too often it seems it's easier to sit on the side of the road and wait for the box to beep to run off and write a ticket. At least I've seen some indication that red lights are getting emphasis around here, I just wish they weren't also taking the opportunity to pull over anyone who might have an inspection sticker that's a week too old while they're at it

10-13 over is reasonable, honestly when I'm driving I seldom see the high side of 80 and I'm not often on the highway either. I still say this stinks and it goes after far more than just speeders too. Potentially changing lanes sans turn signal could get you into this little program. The list of offenses covered by this new law is over 3 pages long. I'm okay with the 4time DUI guy getting nailed to the wall but frankly I have to wonder why that person would even have a license at that point. That we have lowered out BAC to the ppoint that a SINGLE drink puts you over the limit is also irritating to me. I do NOT drink but I think it's disengenous to lower the limit that far and still allow folks to drink anywhere but their homes. As expected this law is about money. Instead of asking everyone to pay their fair share, and I would, he has taken the path of lesser resistance much like those who ask us to "Do it for the children" as no one would dare say no to that right? What will he have to say the first time someone attempting to avoid one of these tickets by running gets hurt or hurts others? As to his comment about retaining counsel, we did and it cost $1500+. It had nothing to do with what it would cost monetarily and everything to do with preventing other penalties. We coudl afford it, not everyone can and people WILL run. Permanent points is an interesting idea. If I could feel completely comfortable that the police wouldn't abuse their new found power I might even be for it. However three times in my personal past I've seen evidence otherwise. I have also hung out with officers at the local speed shop and heard them go on and on about how they love to go "get those ricers". This while having their damn near unmuffled Mustang deafen us on the dyno. I'm quite sure that not every officer acts this way and that there are many fine examples but it only takes a few to spoil things. Given the potential for abuse that permanent points would imply there's no way I could go for it having witnessed what I have. It's sad really, when I was a kid I looked up to police now I fear them if anything and I most certainly do not trust them - I'm not alone.

Actually no, there's one in Woodbridge area thereabouts that checked our's. And yeah finding one was a BEAR! What kills me about this thing is that because of the double jeapordy rules they cannot do this as a fine - instead it is a licensing fee. What does that mean? It means that only VA licensed drivers will be "eligable"! They did this because of revenue, they have finally flat out admitted it. They have really redefined aggressive driving too. Most folks think of the twits who weave as "aggressive" but here it means anyone who is speeding and any number of things that most folks wouldn't call aggressive. when most folks see "aggressive driver imaging in use" they don't realize it means radar cameras - these signs greet you going into Maryland.... I mean really, who isn't for stopping Aggressive driving? These days it's like doing it for the children - no one dares oppose it apparently. A friend knows both a judge and chief of police out West of me in Winchester. NEITHER of them are happy about this. Why? Judge hates it because he has no say so over it, if someone is disadvantaged too bad. Short of dismissing it the person is hosed. The chief of police hates it because *bingo!* he knows damned well people WILL run once they realize how much this garbage is going to cost. People can and do run fairly often too - especially in the smaller towns - bikes are the worst. As for 80mph, in VA that is reckless no matter what. Anything over 80 and that is what you get nailed for. My SO just got a ticket awhile back for 91 in a 65 that we thought was 75 (we were out in the sticks). I was IN the car and I know damned well we weren't going that fast because I watch the speedo'. 81 MAYBE but not 91. The car isn't real comfortable at that speed (I tried with a GPS and backed off before hitting 90) and the speedo' reads over 5MPH fast at 55mph going even further off as speed increases - thank you VW. The speedo' would've had to read close to 100MPH, no way would she do that and me not notice (in my car too) plus we had one of the g-kids in the back. We didn't even try to argue this, what's the point? In Kangaroo court the cop can say anything he wants, even lie (I've caught them at it to no avail), and the judge will believe them. The radar gun is a magic thing to most judges, it's sickening. She got lucky and didn't wind up in jail or with a suspended license nor did she fall under these new rules but wow it could've been REALLY ugly. If she makes so much as a single booboo in the next year she's toast. I've been telling her about some of the crap pulled by the police and she's even seen a little of it riding with me but this really opened her eyes to just how badly you can get boned. Some of the folks I work with are real smug and chant the do the crime do the time mantra at every opportunity, I SO hope that one of those twits finds themself in a situation like we did - this could have cost her her career. I'll never forget the silly prosecutor telling her that she'd not gotten a ticket in 16 years, as if the prosecutor would actually get a ticket if pulled over. Then the prosecutor had the gall to tell her to get a slower car - I think a diesel sedan is slow enough thanks, it took all my willpower not to tell her off let me tell you! Yeah, this new law is a sore spot for me and I will be more than happy to help vote out the twit who helped it along.

Some is apparently rated for EFI. If it's seamless I'd be more tempted but not all of it is I don't think. Aluminum fatigues too so while it might hold fine on day one on day 100 it might not. Even a tiny pinhole is a disaster waiting to happen at 50PSI. I run braided line personally and while it too has issues I'm more comfortable with it than the solid stuff. Certainly some folks get away with it but I've seen what occurs when a fuel line fails catastrophically - it was the Challenger waiting to happen, luckily it was a cold start with the hood up. I've also seen fuel injector O-rings fail suddenly and badly, that too is a complete mess and a disaster waiting to occur. It doesn't take much of a fuel leak at all to ruin your day. To each his own I guess but the solid stuff certainly is cheaper!

Until I'd seen it posted here I hadn't thougth much about returning it in the back actually. On the late model Corvettes that do that they are probably adjusting the pressure by changing pump speed, I know the late model Mustangs do that. However doing that with most any programmable EFI isn't going to happen, I've yet to see one employ that. Even putting the regulator in the back is an issue unless you're willing to run one looong vac line back there - doable though I guess, maybe a hard line? On a forced induction motor this is a must as pressure has to increase with boost or you'll run it lean. You could tune around this but you'll end up running out of injector more quickly - it's a headache tuning around stuff like this to say the least. I actually had an issue on the Supra where my two pumps were overrunning the regulator after they had broken in. At idle pressure climbed like 15 PSI when warmed up and couldn't be adjusted lower. Once running it dropped to normal and the tune was fine, only idle was screwed up. I ended up having to stage those pumps as the small pressure momentary bump when the 2nd turned on was easy to ignore - unlike the super rich condition I had to fight down low with teeny tiny injector duties Aeration worries me not because the engine might stumble but because when it does it's LEAN. Return fuel right next to the inlet (like my cell) and you can churn things up pretty good. I once tuned on a guy's Honda - made BIG power on the dyno - like 600++ at the wheels at reasonable boost. Took it to the track and it knocked like mad and had all sorts of issues going down the track no matter how much fuel I put into the tune. Finally it blew a head gasket (copper too) and I could never figure out WTF was going on - it had run flawlessly on the dyno. Come to find out from someone else who finally figured it out that he had mounted the fuel cell sideways and on accel fuel was running away from the pickup - doh! Learned a couple of lessons from that, seems he never noticed the low mounted fuel pressure gauge fluctuating down by the shifter Fun stuff

Well shoot, just looked under the hood of mycar to see how close the JTR mounts come... no way This thing is smaller than a normal pump but if it sticks out much at all it's not going to fit, that stinks. Sorry, maybe on the Fords? As for electric pumps being noisy - they don't have to be. If you buy the big coffee grinder ones they will be but I've not ever found those to be real reliable anyway. I like the Walbro small ones like OEM's use in-tank. Aeromotive is even advertising their big pumps as in-tank capable (always have been so far as I know) but I doubt even THAT would quiet them much and mounting them in the tank is a puzzle. Walbro has some external ones too but priming and whatnot could be an issue with a fuel cell like mine. I seem to recall one of the Econoline vans was good for these pumps. Guess maybe it's back to the surge tank thing I really thought this thing would be a good option but had forgotten how danged close the mounts come to the front of the motor... P.S. It's not cost I worry about. It's the hassle of running the lines and trying to plumb them so they don't get aerated fuel or any other weirdness going on plus the pump priming etc. Still trying to figure out the best way to (easily) vent my cell too without having all the gas just evap into my garage. Umm and is that solid aluminum line rated for EFI pressures? you using that just for a return or hat?

BTW - found an online article for the HotRod writeup of the Banks motor.. -> http://www.hotrod.com/techarticles/engine/hrdp_0609_banks_performance_duramax_diesel/index.html Kewl stuff!

My first post had the WEB site for the manufacturer, I also mentioned the magazine issue that has the article - it's on newstands NOW. RACEPUMPS.COM The reason for the testing has to do with how concentric (eccentric?) driven pumps normally deliver fuel - in spurts or surges. This pump doesn't have a regulator inside but it does have a way to figure out if it's greatly overrunning the regulator somehow. The reason for this is so that at idle where fuel demands are low it moves less fuel and then at higher RPMs moves more fuel. Anyway, the test was to demonstrate that the pressure is steady and doesn't surge up and down as a normal cam driven pump does. It is a variable displacement constant pressure pump - per their WEB site - sums it up well IMO. Honestly, if you'd get the magazine and read the multi-page article it would save much typing on my part. The WEB site has some info as well, apparently they make hi-po carb pumps too and the EFI pump is a bit more than the $299 I saw on their front page.

No, not as bad as that. The old stuff used barrel valves blah blah and a belt driven pump as I recall. This is for normal EFI systems and isn't belt driven. It's a plunger driven thing, most of the info was from the Hot Rod article including some back to back dyno tests with an electric pump and this one - not much power diff on same maps. Pressure fluctuates some at idle but not much and not so much that it's a problem apparently. Has a ceramic lightweight disk of some sort inside rather than a diaphragm. -8 fittings standard, -10 for more flow if you want. The WEBsite has some info, check it out

one of the issues with doiong this that has caused me to drag my feet has been the fuel system - running dual lines, the return into the tank, blah blah - it's a PITA! Well tonight flipping through the July Hot Rod I foound something that looks like it would make life MUCH easier! Can you say mechanical (as in pushrod) drivenEFI pump that mounts in place of the original style mechanical pump?! It uses a single line fromthe back and deadheads the fuel rail - pressure in the line modifys the amount of fuel pumped. Good for over 2K HP supposedly using the big lines. (lol) They listed some issues that occured on cold starts and ways to fix it related to pressure leak down, the valve mentioned might even be nice to use on convential electric pumped EFI systems actually. To my surprise they claim that there's no massive strain on the cam eccentric either which is nice. It's billet construction with O-ring seals and only a single moving part - they claim it's durable too. Check out racepumps.com for info on this thing, if it can be fit between the rail and the motor it might be just the ticket for an easier EFI install! $300 so not cheap but hey IMO it might be worth it! P.S. I see they list SBC, BBC, and SBF as apps - nice!

Ouch, missed that. I know the guys using the AEM sensor bitched about lifespan I'd certainly be looking for one that can be recalibrated in free air!

Somehow I knew you'd jump in Scotty A very good link too - that's the shop that's doing many of the GE headers and stuff - someone else might be interested in that stuff too! for the street I really like an OD trans to keep the highway RPMs down but wow the instant power was sure nice in the car I drove! BIG turbo that made power NOW when you stomped it. Converters always seemed to be the big problem, guy I knew went through several and lockup units never seemed to survive long

You guys might want to read up on the new Banks salt racer. One of the KEYS to making more power on that motor was raising the RPMs. HP is torque factored with RPM, make the same torque and raise the RPMs and you get more HP. They had to significantly lighten the rotating assembly in order to do this. As for the flywheel, I'll bet they made it that heavy to dampen vibrations and store some energy. I dunno' if this motor is a good one to mod or not but getting more power from new motors is usually accomplished by bumping up boost a good bit. Diesel will run incredible amounts of boost setup correctly - till they fail Yeah, I'm driving a TDI diesel these days. REAL tempted to chip it! Redline is like 4K. (lol)

Heh, I have some of those issues still!

Taurus fan like this one -> http://cgi.ebay.com/90-91-95-Taurus-Continetal-Sable-Radiator-Fan-3-8L-Assy_W0QQitemZ160132853557QQihZ006QQcategoryZ33600QQssPageNameZWDVWQQrdZ1QQcmdZViewItem One thing to note with these - use Bosch relays. If you use the generic crap from RadioShack or the local auto parts store it WILL burn up when used heavily. Been there, done that on my Supra (it ran a Taurus fan too!). My Z actually has a Cobra fan on it, biggest difference is the shroud. A good place to get the relays, bases, and serious wiring is Waytekwire.com. Their crimp connectors can be gotten with heatshrink and glue in them. These are serious pieces and is what I use wiring any of my vehicles. they have a pretty nice catalog too http://www.waytekwire.com/

The overflow tank I linked is fairly lightweight. I've got one on my Z so I'll try to take a look at it - it may have a bung welded on it for the fittings. FWIW, I built something somewhat like this as a water resevoir for my computer - the purchased ones in plexi kept cracking. Anyway, the volume of the tank isn't as big as I'd like it and the return is at the top. Until I filled that sucker near to the top the water comping out the bottom was FILLED with air bubbles! It must have been really churning in there - I used about 6inches of 3inch pipe. Obviously not a fuel system but even in this low volume app I was surprised at the amount of foam I generated. I wouldn't want a mixture like that being fed to my injectors for sure!

It would've been nice if they had included which type of sensor each box used. I have an older FJO that uses the NGK sensor and it proved to be quite durable. Talking to guys using the AEM with the Bosche sensor I was told that it died pretty quickly when exposed to leaded gas - not so my NGK. It was pretty darned accurate when compared with other boxes but pretty dirt simple - just an analog output and a display - no logging etc. which I did via the EMS. Looks like W/Bs have really advanced though, the Innovative boxes look really nice! I think having the datalogging on the W/B would be pretty nice. Interesting that others have run into the issues with the ground that I saw on the FJO. Lots of boxes out there don't have a dedicated ground that can be shared with the EMS sensor ground. Doing something as simple as turning on your headlights can cause shifts in A/F reading! P.S. I'd be REAL careful about budget W/B. I actually had and built one of the DIY boxes but in the end didn't trust my motor with it. Tests like this one are a BIG help and I appreciate that they took the trouble to use calibration gas.

Do not do a VVT-i 2JZ. The VVT-i cars have weaker rods and cam selection is more complex due to the VVT-i stuff on the intake cam. I'd stick to the older motors. GE and GTE motors are much the same. Compression is slightly different but you can stack two headgaskets together to bring it back down on the GE. Headers for the N/A head are harder to find but there are a few companies out there making them - I believe BoostLogic is one of them and the ywill ship overseas. I believe that the GTE motors have oil squirters and the GE do not but I may be mistaken - been awhile. The GE intake is a bit wonky, there are ways of modifying the intake I believe. The distributor is also a PITA, it's possible to convert over to distributorless and dump the nest of wires but you will want an aftermarket EMS. In the end you might find that the GE motor while cheaper ends up costing more when you tweak it. Head flow on the GE is something that is debated too but it's "good enough" to get you plenty of HP - GE Supra have gotten into single digits on the GE motor. Supraforums.com is a good place to find info on both parts and differences on these motors. IMO, if I had a GE motor I'd use it but buying one I'd look for a GTE. Hope that helps! Scotty just posted this in another thread - link to a shop making NA-T parts http://www.boostwerx.com/ so if you're looking at a GE that might be worth checking out. DaveH was the Supra guy who really did good things with the GE motor before eventually switching to a GTE head as I recall...
