Turbo Selection

[thatjonokid]

hey guys,

never meant to rebuild my 20 but it cracked a head so i built a new one

it has

-completely reconditioned head..valve grind and seals etc

-ACL race series main and big end bearings

-Mahle piston rings

-Cometic 1.2mm metal head gasket

-Every seal and gasket replaced

-GTR injectors

-Adjustable cam gears

-Gates Racing Triple Strength Timing Belt

-Getting the ECU retuned by MRC Performance with the nistune software

now it comes to turbo...hmmmm

dont have heaps of money so i cant afford the garrett i wanted

someone through work offered me an unused KKR560 turbo for a price i couldnt refuse

IS IT TOO LAGGY? its about the same size as a Garrett 3076

I dont care if it spools up to full boost at about 4000-4500rpm just not much later

advice pls

Too laggy for a RB20 IMO.

A 3076 would be bad, KKR would be worse again. Poor wheels, poor core... just nasty.

+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.

a kkr 430 is too laggy , i'd be scared to think what a '560' would be like

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?

rb20 i'd look for a 2nd hand GTRS

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?

I wouldn't exactly have put those two lines in the same post

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?
