Engine sizes

[speedyblue]

If you are going to go for a V8 just slot a new chevy 5.7L engine in there. Why waste time with old technology. Easier than supercharging or NOS. All alloy, so you don't get the huge bulking weight. The engine can easy push 450-500hp naturally aspirated while keeping up to emissions on pump fuel, plus it is fuel injected for reliability and all the rest. just butt up what ever gearbox comes with it from the factory.

Surely Australia isn't the only country tweaking these engines.

1hp per cube is as easy target, so 330hp from a 350cui is a bit weak.

Dragon, if you are serious, and still in the market, I have a pretty expensive motor for sale--but about half the money that is in it. There is about 20 hours on it. 383 stroker with every imagineable trick and tune. Completely built. AND: originally built with super- or turbo-charging in mind, so compression is only in the 8's. As it sits now--NA--it puts out nearly 500. Need about $6000.

hey speedyblue WHICH 350 IS ALL ALLOY? Not just any one! And i'm sorry but V8 chevy's are very old tech. They are barely on fourth gen V8's and those are no longer 5.7L. Let's see twp vlaves per slug, cam in block, no variable cam timming, no OHC or DOHC. And 450 to 500 HP AT the Wheels is very easy to reach, just not as cheap or easy as you make it sound. Any chevy all aluminum are not (vette engines are ranging from $2500 and up+harness & ECM) will set lower and farther back in the Z. Giving it better weight distribution. And only about a hundred pounds in penalties. It would actually be much easier to "charge" or "squezz" the Mouse motor than to rip it about to build it up. The TH350 fits and the 700R4 can also be used. Or other high end sticks 5/6 speed can also be used with fabrication and some work. Any thing in these mentioned combos will all require WORK. But there are many kits and references out there now for 240Zdragon72 to use. 350/383 4V 700R4 R200 would be the most simple. O yeah fats out back! :devious: Frank13

Hey Frank13, would you happen to have a website on hand? If not, I can hunt for some of them. Just need the one that shows what type of work I need to do for the 5 speed trans.

Thanks

[frank13]

What model Z? Which trans are you gonna use? I have noticed a few bits of info here and there in these forums. But they are more comments. I have looked through the drivetrain forum quick like but did not see a "how to" that would describe it in great detail. I find going to other clubs forums not too easy to navigate. Though IZCC seem to have much more tech articles. I think a group effort here by these fine members to produce a indepth "how to" for this very thing should be put together. Then A complete tech article could be posted proper like. Get back to me with your info and i'll help as much as I can. :devious:

[frank13]

O crapola 240Zdragon72, we're you asking about american five speed like the T5's or T56. For the SBC thingie you wanted to do?

If that's the case i'll help you with that too. First decide what engine you wanna use and the likes. This will take more work to get it to come out right. In tranny mounts mostly, then slave cylinder. But it can be done with a Small Block Chevy in the Z, just much much more expensive. These type trannys are prized in pro street and hot rodding circles. Drop me a line. Frank :devious:

Frank,

I have the issue of Super Street with the sleeper cars in Cali. I would kike to put the 383ci mounted to a T5 trans. But, I don't have it with me right now. I'll have to get back to you with spcks.

I also have the R200 diff and the 280ZX Half shafts. Right now, she has the L28 from a '83 280ZX and the original diff and halfshafts. I'm completely restoring her for the street. I did want to race her, but I don't think I have the expereance to do that. I'd reck in the first race. Anyway, I'll get back to you soon with the specks.

Single cam pushrod two valves per pot. I was thinking more along the lines of port design in the head and general efficiency and fuel injection, as compared to 10-20 years ago, and carbs, which are still good if well maintained.

The engine I was referring to was the Gen III LS1, which is alloy block, alloy heads, but isn't 350cui. Mounting this in the lower position referred to would mean a better handling car again. Add a hotter cam, decent set of extractors and reprogram the computer and you get a good lump of power, but more importantly torque. One good streetable engine.

There was someone on HybridZ or somewhere who was doing this swap and had his story on the net. Thats what made it pop into my mind.

[frank13]

Hey all, yes speedy blue lower CG for the V8 will make for a bit better response in weight transfer. The LS1 is a 5.7L motor! Aluminum block, Croosbolted mains, very tight tolerances on the assembly of all parts in the block. Aluminum heads, mulitport FI. I got a small list here.

All are Third Gen. Crossbolted. 5.7L "LS1" Aluminum.

These are the more recent offerings from Chevy. There are other, older Aluminum Engines. But these are state of the art int terms of production quality and assembly. To use any of these motors from say a bone yard the way they are, you'd need the complete engine harness, sensors, fuel pump, relays, ECU from the donnor car. To use It's tranny Auto ot Stick, same thing get all the linkage and tranny harness(for lock up convert clucthA/T). The more bits and pieces you grab that go with the transplant set the easier it will be to fabricate the parts you will use. By either adapting the donnor parts or figuring how to make a new one that will work for your application. Having the original parts for reference helps.

To use just the stock set up EFI you could also get an aftermarket wiring harness kit from somebody like "Painless" for the motor you want to use. There are a couple of other companies other than painless, with less expensive kits, but I don't remeber their names right now. Also i do not know if they are complete and ready to install for a running motor now or require modification. Such them being a general kit for a FI setup.

I'll look for some of the threads/posts here for the T5. Post them latter or PM them to you since this is not the forum for that.Later:devious: Later 240Zdragon72, speedyblue.
