rs2 2.5 and turbo

[rxl]

Hello,
wanted to ask if somebody is running 2.5 stroker rs2 or billet rs2 turbo and e85?
what are the advantages? does it make sence to do 2.5 and rs2 turbo ?

[AndyP]

I use a GT3071 on a stroker and I thought that was quite small, but an RS2 is smaller still. The billet RS2 works great on the 2.2, if you want a stroker go a bit bigger.

Pisobiker did on his original build and the RS2 turbo is way too small for the engine runs out of puff at 5k IIRC. Billet wouldn't make a difference it would need a change in hotside.

Better off picking a better sized turbo for the engine. I ran a 3076r and a Compturbo on the stroker. Ultimate depends what you want headline figures or driveability. AndyP's setup was more driveable at low speeds than mine, but mine came if harder from mid range

it doesn't make sense to use a small turbo on a stroker

It never makes sense to use a smal turbo ��

Over 700nm on my stroker and over 400 bhp from 4k rpm to 7.5k rpm says small turbos for the daily win.

well i would like to get aximum torque and sooner the better. dont realy want to run big hp.
so what is the best turbo for that?

[diesel des]

What bhp do you want? Happy to use any type of turbo?

[rxl]

havent driven anything faster then 280hp s2 so dont realy want crazy numbers.. i tking something like 450 would do... but i want fast spool and lots of torque.sadly i would like to run rs2 filter box becouse of the optics. brand of the turbo does not realy matter.

[diesel des]

Have a look at my setup. It does 450 bhp with fast spool and response. I'm using an efr5867 turbo which is compact.

Or I have a gtx2867r turbo for sale which is compact and should fit with rs2 airbox ok. Just needs a t3 manifold. Would do 425bhp maybe 450 bhp.

Put a K27 on it. Spools good and has good top end and is very reliable.

[Jamo]

maybe a gtx3071r there's no right choice here really

[vti2]

Garrett is not reliable
