Yes, the differences we are talking about are smaller. But still, with the data that is presented, the RB with 400cc less displacement is making more power with less boost (apparently). I attribute that to the VE and the higher redline. It's not a question of hp/liter, but pure and simple HP.

MS, I agree. And to this

That's fine if you want to compare a 1cc engine to a 1000cc engine, but when we are talking about a 15% difference in displacement with similar materials, the dominant factor in how the engines make power is the actual redline and the camshaft/compression.

I'm sorry, I don't buy that at all. I don't believe there is anything inherently higher revving in a smaller engine, or that a smaller engine automatically makes more hp/liter. Without going too far out on limb I will say the RB26DETT makes more power with less boost than the VG twin turbo because it flows more air. The resistance to air flow is what builds boost. As a result, the engine has a higher volumetric efficiency, not to mention it revs higher.

I think my compromise with the Eibach progressive rate springs and Tokiko shocks works well on the street and I sure have fun on the track. I'm about an inch lower than stock, which on a '78 was fairly high, but at least I have my fillings on these rough Denver streets...

Wow, what's the model number on that monster?! Is that a T88, or is it bigger than a T88?

If they are bigger than 17", RICE! But that's a nice looking wheel.

Saw this on Ebay (not going to buy, not enough flow even if it's right). A proprietary Nissan injector that flows more than the turbo injector, but looks EXACTLY like the 19lb stock N/A injector. Hmmmm, what poor sucker is going to buy these for a stock 280Z, and find the car runs just fine, in fact, great, as it has new stock injectors...?!?! Ebay 300cc injectors?

I suggest getting the injectors you WANT to use, then make rails to fit them. There are lots of materials and fittings out there, you can do almost anything you want. No need to limit yourself to stock rails that may or may not work.

Cool - the pictures are finally showing up! What about a wastegate flange? I did not see any provision for the wastegate, and the T4 turbines will not be internally gated....

No, on a '78, all the EFI relays are under the cover on the right fender, by the fusible links.

Bahahahaha!!!!! That's Shane, on one of his slower runs at Bandimere. It's a 240Z.

to you! It makes the V8 conversion into a ZX sound easier than the Z!

I ran the G-Force DRs on the street for a bit this fall (215/60/14). I absolutely hated the soft sidewall, I always felt like I had to granny around the turns (they stick, but they are sloppy). I also drove them a bit in the wet with no problems, but I was, of course, taking it a bit easy. They seem to be ok...

The main ignition power is supplied during the 'ON' and 'ST' positions.

All this explanation certainly has it's place, and I'm not going to dispute any of it. I know several folks who just mix and match components like this, and I think David's done a good job with it. He says the ride height is unchanged and the ride is more firm - that sounds good to me, and I don't doubt it. It's a frickin' turbo spring! I'd expect it to be stiffer, more torque, more squat to counter.

T5 turbo? What is that? Are you sure it's not a T25? or T28? Try this site, they seem to have pretty reasonable prices... hoses and clamps

That stuff looks really good Jeff. I haven't heard of a 0.70 A/R T3, but that sounds like a good size for a street application. I'm not sure the divided housing will buy you much, unless you have a 6 into 2 type header that directs the flow from 1-3 into one side and 4-6 into the other...but you are doing a custom header, correct? And the 62-1 looks like it might be a choice.

That turbine is rediculously small. Run away. The stock T3 turbine is a .63, and it is on the smallish side. Why do you only want to run 10psi? You can do that with the stock turbo, even without the intercooler.

That's nice, about what I get on my '78 with Z31 ECCS and 3.90 R200. Averaging over 80mph too

Hi Shane - I'd seriously consider buying it. If you let me make some measurements on the wheel, I promise TEC would not hear about it How did it spool on the street? No spacer needed on the manifold?

I'm considering the same thing, and would like to get 350-370 rwhp out of a T3/T04 turbo. On paper, the TO4E 50 trim looks like a better compressor for a 2.8 liter, and I've heard favorable things about this compressor on a street-driven Z. Technically, what is a stage 3 or stage 5 T3 turbine? How does it differ from a stock 280ZXT turbine? Does anyone here run a 0.82 A/R on the turbine housing, and how does it affect spool up? With the 50 trim wheel (on paper, mind you), the compressor should be spooling to 7 psi at 2000 rpm - this is probably not possible with an 0.82, and maybe not even with the stock T3 turbine. It should also be able to get 20psi at 3500 rpm, and no other compressor even comes close to this! Oh, and does anyone know if the 50 trim compressor will fit on the exhaust manifold without interference with the intake? I'd hate to space that out and lose my pretty stainless downpipe.

I saw these posted on another site. Seriously, the name of this wheel is "johnson 9"

I'll tell you why. The Zed has a huge engine bay, fits V8s and straight 6s with ease. And the weight distribution on a stock Z is damn near 50/50, so minor handling improvements with lower weight futher back can be made, but stock is hard to improve on! And someone else mentioned resleeving an SR20 at the 400hp level - good grief, there are so many stock block options that can take you well beyond that mark. I'm not knocking the swap, although it may seem like it, but there are many easier and cheaper swaps out there that can deliver reliable power.

I don't think the diesel oil pan will fit - it's sump is in the front.
