Rb30/ Rb34

[Davyboy]

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

Thats because it hasn't even been sold yet. The business owner is planning to drop one in his own car as a test bunny.

[Davyboy]

mmm i wonder if its the same one im looking at then....... The one im looking at is from a company called Spool Imports

is it that same one?

[heller44]

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

Spool hasnt sold it yet so i doubt anyones tried it

He himself will be the first test bunny and give back to back results from his car running a t04z setup

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

I have the whole kit coming in about 4 weeks for this. It can run down V8 Supercars with a novice driver and basic RB25 so 3.4 should be fun.

That can run down 888 racing n HRT n the likes at Wannaroo i want one

The V8s in the Vid are Ex Toll and the Black one is Ex Perkins. Would need a Group 1 driver and an extra 150K to run with the Factory teams.

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.

[Davyboy]

ah right

ill have a search and see what i can find

TO4Z would create some decent power lol

[WHITER33GTS-T]
