Hello

I have a R34 GTT with every things done to it but not the engine, have apexi power fc, ehaust air filter.. but I spent a heap of money making the car look like a R34 GTR

have done all the guards interior , MFD screen bumperbars . wing wtc.

Now I want the engine to go with it, or maybe even the 4 wheel drive

I just want to know if I go RB26dett what do I need? and if I stay with my RB25DET can I get a plenum for it?

Help me, please

1998 GTT Yellow

stick with your motor, cost of the 26 wont be justified IMO unless you spend $$$$ on it all.

And i guess you only want the plenum for a 25 to make it "look" like an RB26? Even if there probably is a performance hinderance yeah?

Joel, if your car is a daily driver than you will thank yourself for sticking with the RB25. I have one of each of the R33 turbo collection and find the 25's easier to drive around town generally, especially the auto although I drive the GTR because I recently had back surgery so the seat holds me in place better and the wider track and better suspension kit reduces body roll.

Other than the driveability, there are few impediments to the installation of a 26. The cost of the engines though is a bit high. I noticed you didn't mention a larger intercooler which is pretty well mandatory for safer power production.

Forget the AWD installation. It is just prohibitive if you are going to pay someone else to do it. I had a discussion recently at a workshop about a guy who put the awd out of a GTR32 in a VL and the were literally hundreds of custom parts. If there were even a fraction of the parts needed to fit to the RWD variant (no I haven't counted but I have considered the difficulties) it would still be an expensive project.

Make a few searches and look for the discussions that are available on the subject. There is nothing wrong with what you are attempting, but if what you want is a GTR you would be more satisfied with the real thing.

put rb26 shotpeened rods with forged pistons in your 25 bottem end and you will have a really strong engine at very minimal costs!!! Thats the advice I would give you if you ever considered the rb26 trasplant. Also as far as plenums are concerned I would run a trust greedy style one that is made for the rb25 head witha 75mm throttle body, they look great if thats what you are after!!!??

    • Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
    • I also used NP   That’s were it’s seems to be the best place to fit it? All schematic shows also that it’s should be referenced from the turbo housing. But idk, I do see high hp cars without any connection or anything to their turbos, so I really don’t know how they connect their things
    • I do have loctite 243 and 246 and a few more models. I could drill it now in place and make new threads for m12 and order an4 - m12 coupling and fit that to the turbo. Run a braided hose to the EBC which I could get a an4 to 1/8npt 
    • So M12 and sealant should be fine?    NPT ” because that’s what I had and what I could get atm. 
    • Wouldn’t touch par if they gave it to me. You need to ask how much power you’re looking to make and then add about 50% to it because that’s what you’ll end up making  The factory box says no more at about 350kw or so, the upgraded synchro boxes won’t handle much over 500kw for long and at that point you’re looking at an auto or dog engagement manual,  once you’ve gone dog engagement you may as well go sequential, they cost a little bit more but it’s worth it  also while you’re at it you should upgrade the transfer case with 10 friction plates
