this might only be interesting for me, but some people might find it cool: http://cgi.ebay.com/ebaymotors/240Z-260Z-280Z-Fairlady-Z-car-Turbo-Adaptor-T3-flange_W0QQitemZ360226036635QQcmdZViewItemQQptZMotors_Car_Truck_Parts_Accessories?hash=item53df251b9b its really funky, aparently it bolts to the end of the NA exhaust manifold! The seller says that it might not even fit on left hand drive vehicles!

Is it really that easy? i'd heard that swapping the zxt dizzy was bolt on if i get the oil pump shaft from said zxt and that if i couldn't find a shaft i could somehow grind the collar on the zxt dizzy to fit the NA oil pump shaft. i'd been planning on adapting a 300zx dizzy to my motor for an upcoming turbo swap, people keep saying to get a turbo distributor and change out the internals but the zxt's are getting pretty hard to find these days. So i was looking at some way to adapt the 300 dizzy without needing a 280zxt dizzy and by doing something like swapping out the collars with the NA distributor i could get away with it. Sorry if i sound like i'm rambling and anyone can feel free to shut me up:mrgreen:

few things: yes, i have searched my ass off on this subject so please refrain from yelling at me. Now that thats out of the way, i'm just asking for someone to give me information on what exactly is required to do this swap. From what i've heard, i need to change out drive spindle on my oil pump, and at some point i'll need to do some grinding on the dizzy... Thats about all i've got, so if somebody could point me towards a writeup or just give me any information it would be greatly appreciated. Also, i've noticed from my haynes manual (keep in mind it gives no exact measurements in its diagrams) that the NA and Turbo distributors might be able to interchange collars, can anyone confirm this? I'm not telling you guys to do the searching for me, i'm just at my wits end with this.

When you install the EDIS trigger Wheel you have to cut off the front belt slot off to make it clear the radiator, which happens to run my power steering pump that's why I'm concerned for my power steering. I know the whole power steering setup is extra weight but this car will also be my daily driver

Hey guys, I'm still kicking around the idea of what ignition to use on my future turbo car. I like the idea of edis because of price and simplicity but the Main problem I see with it is being able to retain my power steering at the same time. Has anyone been able to do the trigger wheel install and still keep their power steering? Or should I just go with a plain turbo or z31 dizzy? I've done a little searching but to no avail. If this question has been done to death just point me in the right direction and let the thread die

Hey thanks for the advice I've heard of people nodding the z31 dizzy but had no idea how it was done thanks! Also I would go edis but don't want to give up power steering on my ZX.

Like the description says I'm converting to turbo and need the turbo dizzy with the sensor in it for use with megasquirt. Also a decent condition dash would be awesome. Hit me up so we can talk about prices.

If you could find a cat smaller than the stock one then there should be no issues, the only thing i can see being a downside is flow, but it won't flow terrible enough to hamper performance that badly (actually i can start to see this turning into cat vs. no cat flow flame war. maybe i shouldn't have mentioned it.) as for bolts vs. studs i used the stock bolts but if you want to know the only reason i've ever been told to use studs is because they get better torque readings and you don't have to worry about breaking off old bolts in the head due to torsional stress so not really much of a difference if all your doing is installing headers but then again others are welcome to share their opinions and prove me wrong:mrgreen:

yeah shady hit it right on the mark, wish i had that a few months ago! (btw why isn't it stickied here?) putting the heat shield back on is a matter of screwing it back on while the intake is off (thats how i did it) actually while we're on the subject can anyone confirm that having the heat shield on helps in any way? (intake tempe etc)

hey just a quick update for anyone thats still interested in this, it helps to have set of metric wrenches for this job. I found that often there would not be a lot of room to manuever a ratchet around so using a wrench helped out a lot (especially for the end bolts on those motorsports headers). Also FYI (and someone correct me if i'm wrong) there are 5 bolts holding up the exhaust mani itself then there are 6 common bolts with washers on them that are shared between the intake and exhaust mani then there are also 6 (i think) bolts that attach along the top of the intake mani. Also for anyone interested in the clearance issue i had, i ended up eliminating the cat from the exhaust system all together but it would be possible to fit the cat in the system if you don't mind cutting a few inches off the pipes on either side of that would bolt to the cat. regarless of the minor fitment issues (and constant head scratching) i am very pleased with the system. The headers combined with the muffler kit give it a deep aggressive growl that almost sounds like its coming from a much larger engine (not to mention the increase in power as measured by my butt dyno). Also when i was running just the headers, its sound actually rivalled that of a small v8. I urge anyone who is on the fence about it to buy it!

oh ok. i know EDIS is simple and straightforward the only reason i was asking was that i thought i would be able to reduce the amount of wires running all over the place (yeah i know its dumb reason). Ok so today i was looking at my engine bay and didn't really realize how little room there is in between the damper and the cooling fan. Would it be possible to fab a trigger wheel while retaining power steering? I could get used to not having power steering again, but now i'm kind of addicted to the luxury of it:mrgreen:. I have my AC disconnected would there be a way to mount my power steering pump down there (i'm aware its not the best spot in the world for it)

ugh, sorry to double post but i was looking through this page: http://madscientistmatt.blogspot.com/2005/11/megasquirt-ignition-control-quick.html and it says that megasquirt V3 has the ability to read a VR sensor directly, so (theoretically/practically)does that mean i could run MS with EDIS without the EDIS module?

i had meant getting MS and EDIS for about $400, i was planning on getting the relay board so i guess i need to add that into my budget. Like they always say, double your budget triple your labor hours! Its been a while since i've been on DIYAUTOTUNE's site (where i'm getting MS) but i remember MS V3 being ~$250 for the DIY kit and then the relay board being ~$50, guess my memory is starting to fail me. My plan for getting EDIS was to pull it from a 90's ford ranger, the u-pull by me is crawling with them (guy said they have 10+ on lot) and i'm thinking i could get away with nabbing the module and coil packs for pretty cheap (owner knows my dad, CONNECTIONS!) but the rrfpr would cost me another 100+ so yeah i guess i need to reevaluate some of my items prices eh?! Trying to talk to my friends friend about the supra injectors but he's being kind of an ass so we'll see how that pans out. Well the main idea was to get MS up and running and get used to it then add EDIS into the mix along with the rrfpr then start the turbo conversion once i get some more cash behind me. I'd been looking for a 240sx throttle body so expect a PM flatblack! well more research to do, see ya'll

hey flatblack which SVO injectors (part number?)were you running? the only SVO injectors i could find were for the mustang SVO that were 24# ones? I'm probably going to go with the supra 440's i had lined up though. Ok so my plan for right now is to get my Megasquirt kit, EDIS lined up and installed first followed by rrfpr (or at the same time as MS?) just to get a feel for MS and EDIS tuning/install (and also to give me time to recover after the $400+ purchase of said items). I'll probably stay with that setup for a while before installing the turbo and mani, intercooler, installing new/thicker head gasket, tapping oil lines in oil pan etc. Probably install injectors and fuel pump in between the true NA to turbo conversion and the 240sx TB when setting up MS and EDIS. That sound good? Also as far as turbo's go are stock t3's pretty easy/cheap to get my hands on? none of the u-pull-its around here seem to have any turbo ZX's on lot (anyone wanna "donate" one to me? haha) Well i'm off to go lurk for some EDIS info, toodles!

yeah he beats me on the straightaways but i took him to the track this weekend and killed him in the corners (aint rear engine understeer a bitch) also lol @ woldson for having the most posts concerning methanol injection in recorded history(not a bad thing just something i've begun to notice:mrgreen:) ok so i think for ignition i'm pretty set on using EDIS with MSnS triggered by the 36-1 crank sensor. I know somebody on these forums sells trigger wheels and mounting kits for Z's on this site can someone tell me his name so i can maybe send an order his way in the future. ah yes the Q word, or so i think Also if any of the flat top turbo guys could tell me if running the p79 cam hampers performance any? once again not sure about the Z cam specifics, i do know the turbo cam would have less valve overlap but i don't know if its that different from the NA cam as far as drivability/performance goes i know cygnusx1 said that the stock injectors could handle more power demands but i was thinking of running slightly larger injectors just as insurance, good/bad? i'm thinking for garage space i'll just park the car at my parents house (few hours away) work on the car on weekends and holidays and just drive my old bug around or talk to some of the classic z car owners around here if they're interested in helping. thanks again for the replies guys, you're really helping me out here!

Alright just got back from a two hour drive with my friend in his pontiac solstice gxp, so whatever motivation i had to build this thing just got multiplied by a thousand percent:mrgreen: cygnusx1, looking back on your first reply you said that the stock injectors could handle the extra fuel but i always was under the impresion that running more fuel pressure through the injectors (especially with an rrfpr)would work but would cause excessive wear on the injectors and was more a bandaid than anything (confirm or deny?). and actually while i'm talking about cygnusx1 i just looked up the rrfpr i was planning on using and guess what, its a begi so i guess we're on the same page there. huh so i guess mike had the original idea (well i'm sure lots of people had thought about it), guess i'll have to steal some ideas off him too (bookmarks thread). I know a guy nearby me who has a wrecked early model z (77 if i'm not mistaken) so dished pistons are always an option if you guys think my engine will become a pinging monster with this setup. Also one more thing about ignition, everyone is pretty adamant about EDIS but thats probably the subject i've reserched the least so if someone could point me in the direction of a helpful thread i'd appreciate it and yes i did read braap's (aka dr blows my brain to bits) thread on EDIS but for some reason i can't really explain i could never really figure out how it applied to running in megasquirt i thought it was all just a standalone system(don't know why but i feel like i'm gonna get yelled at for that) so ya i think i know enough to at least get a ballpark idea where i'm at as far as cost (once i triple it that is)and what parts to get and what not to get. The only HUGE thing for me is garage space, since i moved to college my engineering teacher has let me use one of the spare spots in the engineering garage to change my oil and such but asking him if i could do an entire turbo conversion in there is kind of iffy (or maybe he'll be enthused and offer to help who knows). So now i think its just a matter of finding reliable garage space and saving up my cash some more, hopefully i'll be getting some overtime this week.

thanks again guys! Woldson, i was planning on setting this all up slowly and adding what pieces i could to the car right now to save downtime (like megasquirt/wideband/gauges etc) at least thats what i think you meant when you said turbo slowly. i'm kind of flip flopping on getting some turbo pistons because to be frank ever since i saw FlatBlack's car was running flat tops it was kind of like a revalation to me,(someone using flat top pistons *gasp* i've never heard of such a thing!) and as far as dished pistons go i've heard the ring lands on turbo pistons are lower than plain dished tops from early Z's would it matter which one i get for my needs (i suppose piston heat needs is more like it).I'm not even going to touch the exhaust liners because quiet frankly i've heard both sides of the story (positive and negative). I was just wondering about the cam (to be honest don't know much about these cams) because the turbo cam would have less valve overlap but apparently it doesn't matter so cool, another thing i don't have to buy! Flat black, yes i have read your NA to turbo and your Flatblack build up threads, and they have been an enournous source of information, just thought i'd add that. This weekend i'm looking into a guy nearby who apparently has a 82 turbo Z and only wants to sell the motor (what a coincidence, i just want a motor!) so we'll see how that goes. thanks again guys

thanks for all the replies guys! so after a quick scan over your responses i think i about have the general idea of what else i need. Something along the lines of a fuel pressure regulator (and probably one of palnet's fuel rails with the pressure gauges on it) would just a rising rate fuel pressure regulator suffice or should i just go straight for adjustable FMU? I am trying to find a turbo cam right now (just finding one by itself is difficult) i assume the p90 cam would fit the p79 (?). i will more than likely be replacing the entire valve train (118k on the head right now) as for fuel injectors i think i could get my hands on some 440 supra's (my friend knows a guy apparently, hopefully he's reputable). I'd do the Ford EDIS system but i really just want to have the car down time kept to minimum (but i will do something like it eventually) and would like to not spend a thousand hours on experimenting with my igntion system. my other option would be to use the method that RTz describes in this thread (http://forums.hybridz.org/showthread.php?t=126055) in his second post he describes drilling a hole in the 280zxt dizzy plate and using that as a trigger for full sequential injection and ignition (this is in the wolf3d section of the forums so shoot me down if i'm babbling here) i'm aiming for a walboro 255 as my fuel pump and maybe get my friend terry to fabricate me a downpipe (he will work as long as its not to hard and theres enough beer to keep his head level). Also as far as a head gasket goes should i stick with a stock height unit or should I go with a 2MM (metal or what?)if i'm running the p79 and flat top pistons. so yeah, feels good to finally have the plans coming together, my friend has been hanging his supercharged Pontiac Fiero in my face so it would be nice to show him up!

ok, school has started, i have a job and i've been saving what little money i can. And with all this in place i am finally ready to give my z the attenton it deserves. My HP goal is to eventually to reach a conservative 220-250 hp i have been researching costs and labor in relation to NA stroker vs turbo conversions and have since only come up with a unanimous answer of "turbo!". So i'm going for it! there are only a few roadblocks that i need to get out of the way firstly: 1: I know that Megasquirt is the end all as far as EMS goes here (cost wise) but is this system newbie friendly and are there any real advantages over other EMS systems, or is the cost of other systems worth it? 2: I know some people on these forums regard the p90 as the holy savior of turbo heads, but i have never seen any flow charts or anything about the p90 being superior to the p79 (i have an NA)in terms of flow and effeciency. so yeah, is the p90 a must or should i spend that money on something else? I've also heard of some folks using the N42 is that any good either? (flow, compression etc) 3: i was thinking about a T3/T4 turbo, would that be overkill or should i just stick with a stock turbo? 4: i'm still not sure about what ignition to use, stock 280zxt dizzy or just using the sensor on the dizzy to act as a trigger for MSnS. i want the luxury of having direct control of my ignition but I don't know if my lack of experience will allow me to do a good job of doing so. Also i've heard of people using the 300zx dizzy in their cars, would that be a better swap than the ZXT dizzy (i currently have an NA so it would be a swap either way) 5: i'm trying to save money where i can, what fuel pumps could i pull that would give me decent flow and for lack of better words "Not crap out on me"? 6: are there any cars that have same side intercoolers (inlet and outlet on same side)that i could pull for relatively cheap, or do you have any intercooler suggestions? lastly if there are any comments you guys have feel free to post them, i am NOT an expert on these cars and i am Not an expert mechanic or fabricator. Also if you guys think that i could make a reliable NA motor for my power demands let me know what setup to use, the only reason i'm hesitant about the turbo conversion is downtime (i know some of you guys can pull these motors in an afternoon, thats certainly not me)

http://www.sr20store.com/home/ these guys have a good rep and will usually hook you up with some deals if you're gonna buy an sr20 buy it here(this is my friends experience i can't say i've ever bought anything from them)

What? its an honest question, i've had my Z for less than a year and i don't exactly know everything about it. I need to know if its something I should be concerned about

Tossing up the idea of going for supercharging rather than turbocharging and a main concern was which cam to use. I was wondering if anyone who has installed a supercharger could tell me if supercharger cam's have the same requirements of valve overlap (or lack thereof) that turbo cams do and if i could just use a p90 head with a turbo cam and run about 8lbs of boost safely using that setup.

thanks for the link, its on an 81 zx 2 seater. I've been looking for a manual forever and this solved everything, thanks again

Heck i'll take the dash too, haha!

So the area in between the speedo and tach is now completely red where it once just said "ok" in green letters, i'm guessing red is not a good color ever so can someone tell me whats going on? also if it helps my oil pressure sender has been acting up and needs replacement, if that is the cause of the problem then I guess i answered my own question:biggrin:
