R31Nismoid Posted April 22, 2009 Share Posted April 22, 2009 Too laggy for a RB20 IMO. A 3076 would be bad, KKR would be worse again. Poor wheels, poor core... just nasty.

2LV8ETR Posted April 22, 2009 Share Posted April 22, 2009 Too laggy for a RB20 IMO. +1. I use a T3/T4 modified hybrid turbo and I'm very happy with the results. It's cheap, pushes 28psi and hasn't failed in 4 years. Comes on at 2700 and screams to the redline.

toffy Posted April 22, 2009 Share Posted April 22, 2009 a kkr 430 is too laggy , i'd be scared to think what a '560' would be like Link to comment https://www.sau.com.au/forums/topic/266622-turbo-selection/#findComment-4550470 Share on other sites More sharing options...
Lithium Posted April 23, 2009 Share Posted April 23, 2009 I'd say it would be much too laggy but I guess it depends on what you are using it for, and what power level you are after?

Cjmartz2k Posted April 23, 2009 Share Posted April 23, 2009 (edited) To laggy IMHO. RB20 doesn't spool dtuff real well. What kind of stuff do you want to do with the car? If you went to the trouble to go forged internals on a RB20, one might assume you are chasing power levels that would involve turbo's that are going to be laggy anyways. Did you already buy it? Is it bolt on, or are you planning on a manifold and external gate or something. If your going to the trouble of a top mount and external wastegate anyways on a budget, I'm a big fan of Holset turbo's. Search on this board and you'll find some info. HX35 sounds like it would be right up your alley. Also, can you please remove the HEEELP! from the title since you, in fact, don't actually need urgent help of any kind and you are just asking a question. I'm so sick of clicking on stuff like that expecting so see somebody needing urgent help with something like a blown motor or "I can't get this back together!" and seeing a question about which turbo or what blow off valve.

Sorry bout that i was looking at buying it then and there almost so i did want urgent help but point taken. have decided to go with the humble KKR430 want to a tough street car with good circuit and drift ability so got all that stuff plus recaro seat and full whiteline catalog almost lol also my speedo just randomly stopped working...not the drive in the gearbox or the bottom of the cable...new dash needed maybe?

Cjmartz2k Posted April 29, 2009 Share Posted April 29, 2009 also my speedo just randomly stopped working...not the drive in the gearbox or the bottom of the cable...new dash needed maybe? Can you see the nib spinning around inside the dash portion if you have somebody below the car spinning the other end of the cable?
