So what type of resins are used with carbon fibre? Polyester? Thinking about it, Danno's suggestion of a full carbon fiber dash would look so great. But I'm afraid if you went that route you'd need to do center console too, and then door panels... and all interior panels while your at it. Another thought for a piece: Center console. NOT STOCK. I hate the early Z center console... I'd like to see something a whole lot higher (to use as an armrest) and contoured to meet the dash/heater control area a bit more smoothly. (like newer cars) Just trying to put ideas in your guys head, because this is something that I plan on doing "someday". I still haven't entirely figured out how I'd do it though. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

I'm sorta in the same boat as Evan, outta my price range. If you do get this going Mike, make sure you get it on zcar.com. There are lots and lots of guys there that will go gaga over anything carbon fiber. Is there any reason that you can't use your carbon fiber moulds for fiberglass parts too? A few thoughts as to what might sell well: Door panels - flat and easy to make Dash & steering column cover Hood (like pete suggested, with vents) Rear hatch with Lexan window ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Now that its wired in, why not hide the toggle switch somewhere out of eyesight and use it as a security device? ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Without dished pistons your compression ratio will be over 13.5:1. Not good. I may have been wrong in the assessment that if you shave 0.020" off the dished pistons you'd get the desired CR. You MAY be able to use flattops and just remove a bit more material, or you could have the P90 bowls opened up a bit to lower compression. I don't know if either of these options is practical. The amount of material on the piston tops must be considered. The reason most strokers out there are 3.1L is because they use the KA24 pistons, which have a totally different design than the L series pistons. They give you closer to 9:1 compression. If this seems like too much work to you, (it seems like more trouble than its worth to me) then I would strongly consider running a high compression L28. Sell your diesel crank, and pick up an N42 head, run it with the block you have. (if its got flattops) Spend a bit of money on getting the head in nice condition, pick up a bigger cam. Talk to Norm Simpers on zcar.com, he's the only one I know of running a 2.9L stroker. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

I just found this great table, it looks to be fairly accurate as well. Remember it list injectors at 100% duty cycle, and generally you'd not want to run more than 80% duty cycle. So just multiply everything by .8. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Mike I just read the latest SCC, and you might try these wheels. Enkie RPO-1's. In 16x7 size they are only 15lbs each. I know you want 17's, and likely the offset isn't offered... A shot in the dark. Discount tire direct carries them. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html [This message has been edited by Drax240z (edited December 01, 2000).]

I would say that you will definately notice a difference in power, mostly low end torque. You will in all likelyhood get better fuel economy too. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Yes you need some 240z rods. Here is the deal: L28 block L24 rods P90 Head LD28 Crank L28 DISHED pistons (more on that later) 2mm headgasket This engine is 10.79:1 compression. You MAY be able to run that on 92 octane. Depending on your timing. Norm on zcar.com runs a setup like this sortof, but he uses 2 headgaskets to lower the CR, I wouldn't recommend that, but it works well for him. My best advice is to run this setup, but take those pistons and have around 0.5mm (about 0.020") milled off the tops of them. This should give you a CR of around 10.25:1. Which is nice for the street with 92octane. (as well as using the 2mm headgasket) ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

****My opinion and a summary of what I have heard and know, this is not based on personal experience with these turbos. By far the most common performance turbo out there for the L28 these days is the T3/T04 hybrid, with usually a .63a/r. Its nice because it bolts to the old exhaust manifold, and will support 400hp+. I can't imagine you needing more turbo than that on a nearly stock engine. If you wanted to, you could play with a/r's a bit to get a turbo that lagged less or more, and shift your power curve up or down. Best to talk to a turbo company about that, bell engineering, or turbonetics, etc. Can't say I recall the specifics on your car, are you running a quality intercooler? ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

I think its closer to 725 lbs actually. The 240z is supposed to weigh 2355lbs, the 280z is supposed to be 3075lbs I think... You could DEFINATELY get the 240z stiffer and stronger than the 280z with 725lbs to work with. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Yup, thats a great idea morgan. Talk to your good friend Ross and let him know what you are doing. He'll be able to set you up again I am sure. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

The VG30DETT is a very light engine, in fact that bare engine is one of the lightest V6's out there. Yes the turbo's and associated piping and i/c add quite a bit. There might be room enough, but you'll likely gain a bit of weight. As for handling, it depends where that weight is gained. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Oh my... that is just incredible. Take the time to follow Pete's second link and read throguh all 9 pages... I've honestly never been in such awe from a car before. Wow. I've always loved the daytona's, in fact for years and years they were my favorite cars ever. This is making me think that way again. I just can't get over that... ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Lets see, I got my turbo engine for $200. Took a bit of talking to the wreckers to get them down there though. -Head cleaning, rebuild, surface plane, valve job, new valve seals, etc... $300 -Timing chain kit (don't use nissan, $$$, I went with sealed power) $95 -Nissan Rings, main bearings, rod bearings, rear main seal, head gasket, manifold gasket were about $300 total. I got a good deal from a guy that used to work for nissan. -ECU - I sold a turbo ECU AND AFM for around $80 together... But $80 for one isn't out to lunch if its for sure working. Check out my turbo info page at: http://members.home.net/drax77/newpage.html then click on the turbo buildup article... ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

I've seen two different ways, both involve welding the cast manifold. (I'd recommend have a professional weld cast, it can be tricky) James Thagard's manifold: Greg Kring's manifold: Neither of these setups is really ideal, but both are good additions to the stock manifold. To improve on these any more you realy would be better off having a header made. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Hey Dan, sorry the ECU and AFM I sold you didn't fix your problems. I know I've seen the 6AL on a zx turbo before, so its my guess that it can happen... MSD should be able to tell you for sure though. The unit shouldn't really need to be connected to the TPS or the ECU as far as I can see. The BTM basically just uses a vacuum signal from your intake manifold, and determines if you need to retard timing based on what you set the dial to. (0degrees - 3degrees retard per psi boost) I've never owned an MSD before, but its my guess that it takes the spark signal from the ignition module, and then determines how to fire the coil. In which case I'd think that the ECU won't even know its there. I am sure someone here has actually USED a MSD 6A/6AL/6BTM before... I'm just guessing really. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html [This message has been edited by Drax240z (edited November 27, 2000).]

Sam, I think you are wise to worry about brakes/suspension before putting gobs of power in the car. Or you could do it all at once. But putting a big powerful engine in a car that doesn't have the brakes or suspension upgraded to handle it safely is asking for trouble. The stock Z brakes are dicey at the best of times, certainly not made for hot laps... ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

I've got a 2.25" exhaust on the stock manifold, with a Rhino muffler only. Its allright, but it does have a drone between 2000-2500rpm, and its otherwise pretty loud. If you engine is set up for high rpm (big cam, webers, headers, etc) I'd suggest a 2.5" system, if its more stock then I'd go with a 2.25" system. I'd highly suggest putting in a resonator in the trans tunnel, or as close to the manifold as you can. Being close to the manifold will cut out the resonance. For a nice european (read: V12) sound I'd run a low restriction resonator, and either resonated tips, or a supertrapp. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

I appreciate where you are coming from Al, we are all on a budget of some type I think. Honestly though, if you spend the $30 on the JTR book, I guarentee that you will make more than $30 less in mistakes. I really don't think you can get all the info from this site. Granted you could probably engineer it the JTR way without the book, but that said you will save yourself more money in the long run by having the book! Good luck. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Are those numbers at the wheel? (hehe, no LSD) If so, those are decent numbers, though it does sound like you could get more out of it with tuning. Remember that guy with his stroker just dyno'd at 175hp at the rear wheels. Love that program, I think I should get it. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

My advice is to find yourself an R200 3.9:1 open diff and go with that for now. If you end up finding an LSD later on swap it in then. The 3.9:1's are probably the most common ones out there, you shouldn't have to pay too much. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

If you have a cherry picker, it really shouldn't be any more than a weekend project. All you really need to do is get the mounts from JTR (or have them made) and get your driveshaft shortened. (I'd suggest doing this after all else) Make sure yau have the JTR manual and follow it. All the hard parts are allready done really. You'll just have to concern yourself with new rad hoses, etc. ------------------ "Gimme Fuel, Gimme Fire, Gimme that which I desire" -Metallica Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html http://members.home.net/drax77/newpage.html

Ah gotcha. I was thinking that you had made a rising rate regulator. (one that rises with boost levels) I've just realized that I don't need a rising rate regulator though, if I can adjust mine I should be able to meter it using the SDS. Yet another project to do before spring rolls around.

Looks good Simon. I looked at your problem and really didn't have much insight to offer at this time. I had a question about your FPR though. You made a rising rate FPR, correct? Could you outline the basic theory behind it for me?
