Hey guys im about to embark on an engine build for my R33 GTS-T

The engine will be a RB30 block, with an RB26 head with twin turbos.

i was looking on the net and came across a website that sells a 3.4L stroker kit for an RB30

I was wondering if putting that in would be much of a gain? iv searched the forum and cant find anyone that has done it.

It would give me more displacement and torque obviously, but i guess that would also cut the ability to rev down as well

Would it be worth it?

cheers

There is only one.. as far as I know.. there was weird offset ground one off thing, but no production kits.

Look in forced induction - rb30 conversions subforum

Davy, I highly suggest thoroughly reading the RB30 subsection of the Forced Induction forum.

If you have any questions after that, then post up or PM me. Haven't done a 30 with a 26 head but we've built them with 25DE and 25DET heads so will advise where I can :(

And yes, Spool Imports will be making the 3.4L stroker kits. I believe he has two set of pistons and cranks ready to go in test engines, I wouldn't be holding my breath as to when they're available though. Which in that case, if you really do want to go RB34 at some point, maybe a stock rebuilt (freshened up) bottom end is the way to go until the 3.4L kits are released.

cheers for that i wasnt aware that it was only a test package lol

bubba: i have read the subforum. from what i understand the 26 head will bold straight up, just needs a little modification, but not as much as the 25. i will probably be in touch when i start the build :down:

hey davyboy, im looking to do a similar build your doing, 3.4 stroker with a single to4z, ive got a few parts together already and im hanging out to see how this kit performs.

ive heard about spool doing a 3.4 stroker kit but a friend has told me that a comapny called nitto performance engineering are doing a sroker kit aswell but there are no details on their website yet.

      Boost level and torque curve

      There is a LOT of stuff that can be done, it all depends on how much time and money you want to spend on doing in.  Not all ECUs will be able to do it, and the more control you need the more time and knowledge needs to be put into making it work.  If you're willing to spend the time and money and have the right hardware and skills involved there's a lot that can be done.

      I am impressed with all this level of adjustment. I didn't expect all this possibility

      Boost level and torque curve

      By Lithium · Posted

      Correct.  In the case of the 500kw dyno plot I showed you the car actually runs two boost control solenoids for boost control and a 5psi wastegate spring.  It allows me to control how much boost pressure is applied to both sides of the wastegate valve at any point and fairly accurately control boost target as a result. I've tuned it so that it's able to target anywhere from 5psi to 25psi depending on what's needed.  The target tables I've set up in that car are Gear vs RPM, so every gear has potential for a different boost (and torque) curve.   First and second gear have quite low boost targets, third gear actually has different target boost all the way through the rpm range as it's a stock RB25 gearbox - the boost targets have been chosen to maintain a peak of 600nm (what the owner has set as the maximum torque he's happy with putting through the stock 3rd gear) but it carries that to the rev limiter.   The boost curve to achieve that is something of a ramp up, then hold, then ramp up again and the power curve looks more like a flat line haha.
