I have definetly considered the single option, as well as I understand the benefits of it. Its just not a route I wish to go. Thanks for the info however!

I dont really care about high or low mount as I well be getting a custom manifold anyway. I do want to keep an internal wastegate however.

After doing research all of the turbos I had mentioned above would allow me to do this. However after looking at things, I have narrowed it down to either the GT-RS or the 2560 -10 for me. It appears they are damn near identical turbos, so it just comes down to which one I suppose.

Okay. So I have decided. After doing a good bit of research on my goals and purposes for my car, I have narrowed it down to 3 choices.

One is the HKS GT-RS turbos.

The other two are equivalent versions of the GT-RS, just made by Garrett.

The 2560 -10 that we were discussing

The GT2871R -15 w/ .64 Housing AR (same housing size as GT-RS)

The above two turbos are exactly the same with the expection of the housing .86AR vs the .64 AR. All of the other specs are the same.

How much of a difference in lag vs power will the two housings have? I will gladly give a little power up for a lot faster spoolup.

Comments?

My vote is twin GT2871RS with the 0.60 compressor and 0.64 turbine. They each flow enough air for 400 bhp using 1.5 bar at 74% efficiency. You should be looking at 1 bar boost by 4,000 rpm, which leaves plenty of room for rpm changes on gearchanges etc.

The 1 bar at 4,00 rpm is based on 3 litre capacity with 9 to 1 compression ratio and 264 degree cams with around 9.5 mm lift and some decent porting on an RB26 cylinder head.

:( cheers ;)

    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny 
    • Yea - I mean I've seen my fuel pump which is decades old and uh, while I'm not saying this with real knowledge... but I sure get the ick at using anything in the fuel system that produced the state of that pump. Many years ago I went through multiple pumps (and strainers) before I dropped the tank to clean it out with extreme violence. I'm talking the car would do maybe 50km before coming to a halt, which resulted in me cleaning out the filter with some brake cleaner and going on my way. None of my stuff ever looked like what came out of your fuel tank. I don't think I'd be happy with it unless every single component was replaced (or at least checked/cleaned/confirmed to be clean here).
    • I'm not going to recommend an EBC pad. I don't like them. Just about anything else would suit me better. I've been using Intima pads for a while now.
    • Agreed, and in particular the earth strap that should go from the subframe to the chassis but it often broken or left off. There is a section in the R32 workshop manual you can follow for troubleshooting if you don't see anything suspicious, and depending where you are (there is no location on your user profile) you should be able to get your hands on a second hand replacement unit still if needed
    • Yeah they mention as a R34 for 2.5 Turbo...but then again thos "small" were also for R34 by that different site. But i look into it and that 310mm EBC is for R34 GTT. And by those you linked the specs are the same 🙂    EDIT: I found these on one site here: DBA 4000 series T3 DBA42304S They are 310mm...and it says are for R34GTT...are there good? EDIT2: ok they have pads too.  What "color" should i get for street use? I dont want/need some noisy ones...(and if they are not that dusty that is good too)
