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?

Tax will cost more in Japan?

Scotty, you can't recieve PM s.

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

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!

    • I much prefer that to an actual oil pressure issue, never would of thought it would of been a volt drop issue but SAU brains win again. Guess ill be turning down the oil pressure limit for the track and hunting some grounds. Ill hopefully update this thread with some high oil pressure and solid ecu voltage logs. 
    • You've just discovered a really good reason to tell yourself, yes, I do need to buy an aftermarket ECU. Put the MAF in the bin. Slap in the new ECU and have a think about what turbo sounds you prefer.  Do you want a 90's style BOV wooosh? Do you want a hektik tsututututu?  Mate, can't go wrong. Just gotta get that ECU and the world is your oyster. 
    • Hi. Iam just curisou about this topic. I saw this video. It is about Greddy Type FV2. I know that BoVs are about that sound but how and when to use it? I read some topic here and from what i have understand on stock RB with MAF there will be some "problems" if you use this BoV? It vents the air in to the atmosphere and the MAF on stock car needs this air back in to the intake and not out? Or is it wrong? If so...i saw you can put some adaptor to circule air back...but does that not "loose" that sound? I saw another BoV from Turbosmart and it has two "exhaust" like ports? One is for the stock tubing for letting air back and one is for "sound" and let the air in the atmosphere? Can someone please explain? This is the Greddy one:  And this is the Turbosmart.     THANK YOU!! EDIT: So i read about this topic some more and i if i understand that correctly: That Greddy can function either like BoV or 100% Bypass valve? And that Turbosmart is what they called hybrid so you can adjust what and how many air can be vented out or back in? Is this right? THX!
    • That dirty voltage drop is the culprit I suspect 
    • i cant get them all in 1 screenshot unfortunately as i just dont know how to move things around tbh, but they are all from the same log and the line crosses at the same point for all of them
