Hello,

I'm not a Skyline guy, but I am considering using a pair of turbos from RB25DET's to build a mild TT setup for a small block chevy.

I have searched and searched for info on these turbo's without much luck.

I am mostly interested in the physical dimensions, as I am pushed for space. Can anyone give me this info please?? If it looks like they'll fit, I'll be chasing a couple of second hand units, even a busted one to use to dummy up the manifolds would be great!

Does anyone have external dimensions for these??

Are they at all similar to the t3-t04b/e hybrids shown here:

TIA,

Bob.

Are we talking Small Block as in 350 into a 69 Comaro...

I would be looking at something slightly smaller than the R33 turbos, maybe T28, and these will not have ceramic wheels that due to the N/A engine are likely to cause problems with the higher static compression.

There is plenty of info on the T28's...if anyone has a better suggestion then I am sure this guy is open to ideas!!!

If it's something like a T28, it would be WAY too small for a 350Chev.

I was looking at putting twin T28s on a 231CI (For comparison) was a 3.8L motor, and they would have been WAY too small. Even in twins.

Small block I'm assuming would be something like a 253 small block. Look at something like the twin turbo setups from the RB26DETT

    • Hello everyone. I believe I have s1 headlights but I just wanted to make sure and getting confirmation from you all. Thanks in advance for your help!
    • Crazy how good the aero bar looks compared to the stock one
    • Yes, but you will need to rewire all the things that are different. CAS, coils, etc. Yes, but there is no IAT. What? You can use anything you like. It just has to be hooked up so that it will work.     Or are you wanting to just plug and play without having to do any thinking/work?
    • It's been a little over a decade since I bought the S15. As I did on my socials, I'll share some of my favorite pictures from over the years further below. If you haven't realised, pretty much all the pictures in my posts are ones I've taken.  In terms of updates, I don't have pictures, but I acquired a near-perfect pair of fog lights from a friend of mine, so those got swapped in for the pair I already had. As for the JZX110, I just got it back from being fixed. A few weeks back, I was on the highway when I suddenly drove over something with very little time to react. It was probably the size of a soccer ball, but it went under the car and banged into the underside pretty loudly. I pulled over and realized the fluid leaking was fuel, and of course, it was right near my exhaust. This required replacing the fuel tank. If you happen to be in the same predicament, thankfully this car shares a fuel tank with the JZS171, IS200, and IS300, so it wasn't too painful to replace. Enjoy some pictures as mentioned above, including the carnage from the fuel tank and a bonus picture I came across which shows how ridiculously shiny the Bugels are on the 110. So many more pictures I could share of the S15 but this will do for today, enjoy.
