Drax240z

Talk him out of it Ross! A drawthrough setup is really terrible. Tell him to track down "maximum boost" by Corky Bell. (Wilkison's Automobilia on Ontario street will special order it if its not in stock) There are a whole mess of problems associated with a draw through system, a few less with a blow through system, and a lot less with a efi system. Drawbacks of a draw through system include: No intercooling, it will ice up at ambiant temps less than 50F, and fuel will often puddle in the turbo inlet, and other low points. This leads to a bad idle and low speed response. You can counteract that puddling by heating the fuel after it goes through the turbo... but that has the exact opposite effect as an intercooler --> not recommended. Check out the thread in this forum "3.1 280zx" for some turbo buildup ideas and costs. Any more questions fire them at me. ------------------ "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 [This message has been edited by Drax240z (edited November 02, 2000).]

Argh, don't sigh after that statement. You should have a (yay!) instead. hehe. This has got me thinking too... sounds like the way to go to me.

Yikes Morgan! I'm glad you got that car before we saw one less Z car in the world, sounds like the guy was a disaster waiting for a place to happen!

BLKMGK a good place to look for a few zx turbo tips is Greg Krings website.

Very cool thread guys. Ok, Euro if you are thinking turbo, then I can help you out a bit. My engine complete from a wreckers, with turbo, alternator, and basically everything attached (even heatshields) cost me $300 canadian, they pulled it and delivered it to my door. That translates to $200US. I however did not take any of the electronics! I am going with an aftermarket fuel system, which runs under $1000US. Why? Nearly infinate flexability, and it will always always! be able to accept modifications I want to make to my system. I tore down my engine, not a thing wrong with it. I'm reaplacing all the wear items anyway... another ~$200US. Total head rebuilt with cleanup P&P and 5 way valve job: ~$300US. For the engine alone, that is about all. I'm replacing a buch of other things at the same time, but your 280zx should handle the new found power a little better than my much lighter 240z. HP? here are my estimations and plans for my car: (well, no stage I for this car) o Stage I: Stock L28turbo engine - 180hp o Stage II: SDS EFI, no emissions stuff, 3" exhaust, no intercooler, 8-9psi boost, and mild head work: (P90 head) ~230hp o Stage III: Custom 2.5" downpipe, NPR intercooler, Larger injectors, still stock turbo, 14-15psi: I'm hoping for 300hp o Stage IV: Hybrid T3/T04 turbo - Probably anywhere up to 400hp, but I don't want to put too much strain on my bottom end. I'll likely run it around 350hp max. As for costs... I'm going to be doing nearly everything myself, and I'm always looking for a good deal. ClintZ managed his buildup for a VERY respecable sum, $3000US I think? (clint?) I'm not done yet, but I expect my setup will run me about ~$2500US for up to stage III. That includes a complete bottom end rebuild. Not exactly sure what a T3/T04 turbo runs... Do yourself a favor, find someone to give you a ride in a turbo car that is set up well. Where abouts are you located? ------------------ "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

Morgan, I think you're out to lunch. First off, judging from the 3 or so cars here running superchargers, I have the feeling they'd say they are anything but "really crappy". "underperforming" doesn't sound like John Scotts car to me either. He's said he doesn't want a turbo. Fair enough. Euro280zx. Can you post what you want out of your car? Autocross? Drags? daily driver? Long distance cruiser? All of the above? You can have it all, but you will have to sacrifice a bit... (whether it be in engine operating range, or suspension stiffness, 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

Yes James Thagard is running some serious power!!! Scottie would know better, but I believe that James has run over 120mph in the 1/4 with his L28 turbo. Reading the artclie it really seems like a lot of fabrication though. Is the viscous superior to the clutch system? (I assume that it is somehow, since the clutch type was short lived and replaced by the viscous) Less wear I'd assume... I was pretty sure that the 240SX's had R180's though Chris. Could be wrong, but it tickles my memory. ------------------ "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

My experience is limited to removing 2 of them. I hope you ahve a decent set of extenions/deep sockets/u-joints on hand. Getting at the nuts that hold it on (under the dash) is quite a chore. (on a zx anyway) 12mm deep socket, 2 x 3" extensions and 1 u-joint should do it, but be prepare to lay upside down in your car for a while. Its not a hard job, its just frustrating! As for the master, you shouldn't have to do anythign with it other than unbolt it from the booster. 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 [This message has been edited by Drax240z (edited October 30, 2000).]

Perfect! That's what I'm looking for Sector. I'll give this a shot in the next couple of days. Thanks. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

If you have a stock engine as it is now, why not start small and work from there? You have flat top pistons and a P79 or P90 head on your engine now... Find an N42 in good shape, and swap it on. Run only 92+ octane and get it in tune, and you're on the road to more power. Most of the high performance 2.8's I've seen use this combo. As for a kit, you're really better off to make your own, since then you will know exactly what is going into it. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Morgan is bang on. You have to decide what you want now. Adding a turbo later to en engine designed for a non-turbo application really isn't the best/most reliable way to do it. As for your displacement question, look at it this way. You have a 2800cc engine and you add 300cc's making it 3100cc's. You've increased the displacement by around 10.7%... a 50% increase in power from that with no other changes isn't going to happen. You want EFI, understood. About the best thing you can do will be to open up the intake and exhaust as much as you can, and get something to add more fuel. (bigger injectors, adjustable pressure regulator) I'd go with a 60mm TB, get a turbo afm, or a early 80's BMW 530i afm (swap the guts with the one you have, the beauty of these are that the bore is way bigger) Headers, 2.5" exhaust, more fuel pressure, turbo injectors. Throw in a hotter cam... that's about it, oh, port and polish too. Will you see 250hp? I can't really say... Remember one other way to get your car to feel like it has more power, lighten it!! Don't underestimate the effect of removing 100lbs of dead weight. (the driver! LOL, just kidding) Good luck. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Sorry Myron.... Hahahaha! Just picturing Homer doing the same thing... But it really sucks. I broke my windshield in my parts car getting it out, darn its frustrating. Any idea if there is a chemical process to remove old tinting, I have to do the same thing! ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

My last 240z (a 73) weighed in on a commercial scale at 2355lbs without me. Not sure how much fuel was in it, but I don't think there was a lot. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Ross, have you talked to Dan Giroux about it? he's in your neck of the woods (Surrey) and his personal project car is a 72? that he is putting a TT drivetrain into. He's an ex-nissan tech, owner of "The Z shop" in surrey, and a member of the BCZR too... I can give you his addy and phone number if you email me. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Hey Craig? What did the bedliner run you for the whole car $$$? Sounds like a viable alternative, as long as you aren't planning on doing any welding, etc. after its put in. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Morgan, if you decide that the problem is not to do with your ignition, and is instead something weber related, try contacting ZR8ED on this site, or zcar.com. You can probably dig up his email address with a search here. He's had lots of sucess with his triple setup, and has helped a ton of people with jetting webers. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

True assembling your own kit will save you cash. LD28 cranks aren't hard to find if you are willing to get them shipped to you. Check zcar.com's classifieds, there is almost always one for sale in there. If you are really stuck on efi, then find yourself a L28turbo engine in good shape and swap it in. No fabrication necessary... (hehe, unless you do what most people do and install a ton of other stuff at the same time...) As for websites with modifications, its hard to beat Bryan Little's site. http://www.mindspring.com/~blittl/ZGarage.html Good luck! ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

I don't have a stroker, but I can pass on the info and general consensus I've heard from most of the people that do. Going 2.8 -> 3.1 might net you 15hp and 15lbs/ft of torque. Ask yourself if you are willing to spend $2000? for that increase. My advice is to go with a hot 2.8 setup. Take that $2000 you'd spend on stroking, and put it into a set of triples, and a port and polish. (coupled with the cam you were talking about) Add some headers and a 2.5" exhaust and you can probably see high 12 second 1/4 miles with everything else taken care of. (slicks, soft rear suspension, etc) I know of guys running hot 2.8's that run 12.2 seconds. Honestly I think the money for the stroker is better spent on other upgrades. If you want power over 300hp do yourself a favor and go with a V8 or turbo setup... an NA 2.8 with over 300hp will probably cost you $15,000. (just a guess) And it will not be streetable at all! Hope this helps a bit. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Hey, welcome to the board. Here is the route I would if I was in your shoes. (I'm not doing the V8 thing myself, but I researched the hell out of it before making a decision) Neither the MSA or JTR kits are going to make life too much easier for you, since they are designed for 70-78z's, the zx's are considerably different. I would check out what Ross Corrigan (on this board) has done, since he is one of very few people that I know of that have done this swap. Another bit of advice, buy the JTR manual and learn a few things from it. Granted you can't follow it step by step to put the V8 in your car, but it will show you how to tackle most (all?) of the problems you will face. Driveshaft angles, header selection, fuel line size, etc. Also you are going to have steering rack issues with the zx's. I hope I haven't discouraged you too much. It can be done! But its not going to be cheap or easy. :/ ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html

Hey Mike, sounds interesting! Just wondering, I assume those are your US prices... What kind of deal can you swing for us canucks if we were to come by and pick everything up?

The one on ebay right now is from a 92, which IIRC is a Mark III. (1986.5 - 1993.5?) I'll keep my eyes open for one though.

Morgan, where did you pick up the Mark IV one? Just wondering where to look... also I'd appreciate a picture if you knew where one was. I just realized how huge the ford one is, the core is nearly 10" wider than the large NPR one that Scottie uses, the other dimentions are similar. ------------------ "THE STREETS WILL FLOW WITH THE OIL OF THE NON-BELIEVERS" Drax240z 1972 240z - L28TURBO transplant on the way! http://members.xoom.com/r_lewis/datsun.html
