I wouldn't bother to stroke the RB25, it's a great engine but not the best starting point for huge horsepower. Do you have a horsepower figure your aiming for? There are RB30's being built in Perth with RB26 heads which will provide a better base, or the 2.8ltr stroker for the RB26.

It is possible to get alot of power out of the RB25 so why stroke it?

Might be worth looking at what TRY09 did to his engine. Fitting RB26 crank rods and pistons is also possible.

yeah i heard about get the fittings of the rb26

do they fit straight in

can u stroke it out any further from that point or does it stay as a 2.6 then..

dont the rb25 and rb26 have the same block?/ and whats the diffrence between the rb26 heads compare dto rb25??

i was thinking of going the rb30 block but.. then u mite as well call my car a dressed up VL.. and i dont like VL's hahaha

The 3litre blocks are nothing like a VL once there completed, with fully forged internals capable of supporting 1000hp. The RB26 head design is quite a bit better, solid lifters, bigger galleries, oil squirters etc.

Yes the RB26 bits fit quite easily, I think Merli has done this so it might be worth asking him.

I think it would be better to keep the engine you have while you start to build or have built for you an RB30. This way your car is still on the road and you can pay for the build-up as you go. The RB30's can also be done with the RB25 head, not as good but can save you some money.

can u upgrade the rb25 heads to be as effective as the rb26

such as the oil squirts solid lifters etc etc

or is it imposible or is it cheaper to go get the rb26 heads

[GTS-t VSPEC]

It is possible but not worth the hassle, the RB26 head has a better design in many areas and trying to make the RB25 head the same would probably end up costing more and not being as good.

RB26 head on the 3litre bottom-end is a very strong and reliable build. If your planning on doing the build yourself then cracktest/x-ray all of the parts, you don't want any unreliable parts in a big engine build.

yep cool thanks me and NIk have discussed this issue at work

ive decided to go rb30 block and rb26 heads

hahah

Good to see you've seen the light. I love the RB25 but for serious power there is no comparison. At least this way the car is still driving while you build the 3litre.

Are you planning on doing it yourself or getting a company to do it?

See'ya

haah pleaseeee

half my 6000 cousin r mechanics

they would shoot me if i payed some one to build a motor

plus i wana do it my self as well, so i can learn a lil

Your lucky to have mechanics in the family. I'd suggest taking your time with the engine build making sure over and over that the clearances are right and everything tightened etc. A guy I know put an engine together himself and it dropped a rod, cause he didn't tighten something.

Good luck with the build, keep us posted.
