hey guys this has probably been asked 300 times but im hopeless with the search and dont wanna read an entire write up just to answer a couple of questions..

so here we go.

next thing i might look at doing is dropping a rb30 bottom end with rb25 head...

now can the motor handle it stock? like without bolting a massive turbo on it, it should run fine with a r33 turbo?

and is it a straight bolt in like will all my accessories in my r32 gts-t fit up to the rb 30 motor

if not what needs to be changed

regards

Brad

dont mean to sound rude but dont be sorry, just do a quick search, its all been answered on several occasions

either thru the major thread in the first 20 odd pages will answer all your questions before it goes into major detail about the specifics. or jsut flick thru the topics that this new sub forum has produced. and a r33 turbo will be hitting its limits rather early in the rev range.

Yes it will all work. All RB20 ancillaries will bolt on but the power steering bracket needs to be modified.

Yes, an r33 turbo will hit its limits early.. mine makes 12psi by 2200rpm, ~250rwhp @ ~4600rpm and noses over rather severely at about 5800rpm so bad that by the time it hits the 6800rpm limiter it's only making 90rwhp.

P.S. Search is your friend, people get sick of repeating themselves ;)

    • @Butters I can't tell you why but the bigger HKS step 2 cams improved low and mid end immensely. Turbos started spooling about 1k RPM less than before and the idle/vacuum was rock solid, it was an absolute thrill to drive, 3rd gear pulls hit 180kmh where previously only managed 160. Conversely, the milder poncoms in there now have a funky idle making it harder to get off the line, drives poorly in lower revs, laggy and makes less power/torque throughout. Feels better after I swapped the EBC but unless I put it on the Dyno again, I can't say how much better.

    • Cams are not needed at this power level, they will create lag. The cam gears are a good idea though.
    • @Murray_Calavera yeah, I guessed as much, cooler temps, more boost, less knock, more timing, hello power. Unfortunately not quite within reach ATM, could upgrade my whole fuel system to support but still wouldn't have E85 to run it 😂  Anyway, I changed cams again, 260/260 poncam B and everything else the same except an EBC upgrade. Now I must say I was quite disappointed with the result as it was like running stock cams (didn't try to dial them in as they're supposed to be optimum already) but after awhile I suspected my new EBC was underperforming not to mention difficult to use. I recently swapped back my old EBC and it drives much better now, boost comes on sooner, more stable, no spikes etc, feels all quicker and faster than with stock cams. Planning to fiddle with the cam gears and see what happens but maybe skip the Dyno as I intend to revert to the HKS cams cos they really made the car come alive; low and mid end was unbelievable and it just wanted to rev to the moon, finally knew what people were raving about, RB26 really loves revs. Anyway, Dyno 03 is quite disappointing, in Dyno 02 although peak power was less and trailed off at the top, the low and mid end improvement more than made up for it.
