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.

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...

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.

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)

      Cas issue

      By GTSBoy · Posted

      The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.

      RB26DETT Sketchy boost mod?

      By Duncan · Posted

      Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.

      Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.

      boost source Size Garrett gt28 gen2

      Totally equivalent. Stock often goes from the comp cover because that's where the actuator is also installed and the factory needs 2" of hose to make the connection - and it comes as a pre-assembled unit. They totally have a boost reference from somewhere between the turbo and the throttle(s). Oh, jeez. Just do it in M12 then. We don't actually care that much. I would expect any such AN converter fitting to rely on an o-ring or some other seal onto a flat surface under the flange of the hex**, because bolt threads are no intended to provide a pressure seal. unlike..... pipe threads. **which also requires a suitably flat and smooth surface on the turbo's boss to provide the seal.
