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

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?

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?

      Hey Nismo, any chance in the world you still have these seats?

      Forced Performance Hta Turbos

      I'd say closer to OG GTX3582R, just smaller trim - so 59mm inducer/82mm exducer as opposed to 62/82 for the first gen GTX3582R. Yeah EFRs were boss, the EFR8474 is still an absolute beast and it perplexes me that people still go to things like Turbosmart/Garrett etc when the results people are getting with those are pretty unremarkable compared to what you could get with a turbo available well before those options came out.  DriftSquid (I think) "upgraded" from an EFR9174 to a Turbosmart turbo and promised a comparison video - and kinda shuffled awkwardly and did a bit of diversion from the fact that they didn't get any improvement going to the currently massively hyped brand of turbo from a turbo that was a bit of a frankenstein that had been well superceded in it's own range before the Turbosmart unit he put on there even came out. I suspect the EFR would outperform most Xonas for what a lot of less-insane RB owners would go for, in the 400-600kw range but the Xonas are looking hard to beat up to maybe in the mid 700kw range at this stage- basically where EFRs don't really reach, and before the Precision turbos take over.  What the Xonas do well in the "EFR range" is be easier to package etc, and work very well if a divided housing doesn't suit your application.

      Tomei gasket

      By WMDC35 · Posted

      Are you sure the gasket is blown? What are the issues? Thermocure is the only flush I've seen do anything with rust, very impressed with that, Prestone, rust will be by the pool having a cigarette.

      And since the flush you have a blown head gasket? Have you lifted the head off yet?

      Hr34 fuel pump not turning on

      By GTSBoy · Posted

      The answer is to get a hold of the wiring diagram, work out what voltage is supposed to be where, when, and then work out why it is not there, then. I can't speak to the HR34 stuff, because I have never paid any attention to the NAs. There is a possibility that the turbo diagram will help, but it could also be different - depending on whether there is an FPCM on the NAs.
