2530, Hi-flo R33 Or Hi-flo R34 Neo

Ah true? He didn't mention it, just said maybe cam gears or something from memory. Need to save up a few hundred dollars for it to get dyno tuned again i spose, balls

Did I read that right...? you hit 14 psi at 5800 rpms?!?

Sounds like if you replaced your turbo/manifold gaskets you'd get better spool than if you upgraded to a ball bearring turbo!

Seriously, thats and unhealthy late spool.

ohh no haha i hit the 14 psi at about 4000rpm , 5800 is when i hit peak kilowatts and my power drops off rather dramatically.. geez come to think of it, in 1st thats only 1800rpm making decent power, eww

This might be alittle off topic but then again it could help this guy out...Does anyone have a dyno graph of a sliding performace rb20 highflow on an rb20? it'd be good to compare it to all the other graphs on the rb20 thread...

Just had a look through the RB20 topic and dam theres something bottleknecking my car's performance bad. Most of the standard r32 turbo's are maxing at 140, some 145, mines alot bigger than the standard and it's maxing at 142 so something wack there. Most r33 turboes are making the power about 15-20 km/h higher than i am.

You're damn right there is!

I put down 219 hp, or 163 rwkw, at 12 psi on my rb20 turbo. SAFC, open downpipe, FMIC.

My roommates car made 258 hp 259 tq on his r33 turbo @ 16 psi.

Same here...i've got a standard engine with standard turbo, exhaust, fmic, fuel pump and dr drift remap and it laid down 160rwkw at 12psi too on Sam's dyno...so theres definitely something wrong with how much power you're making...

i gots fmic, fuel pump, remap full zorst and made 169.2rwkws at 14psi

stock turbo too....on sams dyno

[NICKS33]

full boost should be lower....3500rpm on my cousins 32 with 33 turbo...

i thought that the comprimise of 500rpm of response for the extra power up top of the 33 turbo was well worth it...

also running 14psi on the 34 turbo on a rb20 is roughly the same as running 12psi on a rb25....

This was a write up done on Sliding Performance turbo's on an RB20DET proving that even the standard RB25 highflow is more then capable of creating 230rwkw. http://www.skylinesaustralia.com/forums/in...142615&st=0

Your power drops off far too early...

I've got max power at 6500rpm and then at 8000rpm I've got the same power as at 5300rpm. RB20 with R33 S2 turbo.

You should have something pretty similar seeing as you've got the same turbo except the bigger turbine housing.

[123456]

Hmm damn, lots of responses saying it's shagged, sucks that it's not easily diagnosable (<< how the hell do u spell diagnosable) and the fact that the guy who tuned it didn't mention that it was dropping off prematurely worries me, hope my engines not rooted, i thought it was pretty good. Any one know of any dyno nights closer to greensborough/watsonia/eltham area coming up soon so i can see if the cat/dump has made any difference (i normally dont rev the thing past about 6.5k anyway)

[123456]

Just thought id also mention that it holds 14psi till about 5.4k rpm then holds about 13.5 PSI all the way through to 8000rpm, which confuses me more

2530 FTW

made 236rwkw with stock rb20 engine - stock ecu (with FCD) - stock inj - stock afm. (pump/fmic/zorst/pod/bov/boost @ 1.3)

have now made 240rwkw on my RB24 with pfc - gtr inj - z32 @ 1.17 Bar

dyno results in the rb20 power/results thread.
