Rb25 Or Rb26 Into A R32 Gts-T Questions (Yes I Have Researched)

[yoshiii335]

Hello

I am wanting to make my RB20 reach as close to 400hp as possible and keep good response.

I have received many suggestions which are good.

Just to look at the other side so that I can have all understanding of my options,

which is a good engine to put in the 32, a rb25 or rb26?

I read that the 25 is good but it has its problems and cant be boosted too high because of its compression.

I read that the 26 is great, just expensive.

Ive read that the s1 25 engine is easier to wire in than the s2 and neo, but the neo's ecu's is easier to have it nistuned, chipped, etc.

What are the pros and cons of putting a rb25 engine in?

What are the pros and cons of putting a rb26 engine in?

If I do these mods, my road tax and other expenses here in Japan will go up more than double for what they are for the stock rb20.

If it is not neccessary to put either in to get 400 hp and have good response, than I will not.

Once I mod up and tune my 20 , will I have better torque?

Seeing you have access to all kinds of cheap engines, why not shove a VR38 in there?

Tax will cost more in Japan?

Thanks Ben. 400 messages is only a few months worth it seems.

They pay extra registration costs (road tax) by engine displacement I think. No wonder there are so many small engine turbo cars there.

... rb24 time???

26 crank in an rb20 block, custom pistons.... stealthiest way to get more capacity for your 20.

I'd be starting with an r32 rb25 na head, 26 crank, rods and tomei (from memory) make pistons to suit? I think you have to notch the top of the rod blah blah blah

At least that way you retain the rb20 block and engine number, get some more capacity etc pop an hks 2530 turbo kit and ecu/fuel system of choice. Boom done!
