From gt2871 elim to gt3071

[sylvios]

Hi everyone...
I have an a4 1.8tq gt2871 eliminator 630 cc siemens custom tuning .
The dyno was at 272 wheel power and 36,9 kgm wheel torque at 4600rpm.
The car runs very good .
The question is that as i have change my rods so i can run more torque why not go for a gt3071 if there is no more lag. I think that elim is already a little lagy. I see full boost 1.6 bar at 4200-4400 rpm.
Need your opinions about gt3071 in a 1.8t.
The car has already
1. 2.75" full exhaust MTM
2.MTM clutch
3.s3 maf
4.walbro fuel pump
5.007 forge
6.rods IE stone
7.FMIC
So ,do you think that the car would be nice to drive for an every day use with a gt3071
and if yes witch gt3071 do you propose to use and witch manifold?
Thank you.
Sylvios.

3071 will be fine.

are the new rods already in the engine or you are planning to get some rods.

if you haven't bought the rods yet, why not build your motor to 2.0 liter so you can hit full boost sooner.

building your engine is alot easier said than done

Here is my 3071R build

a nice way to put it, ->I know

The rods are already in the engine, i didnt change the pistons so thats why i am wondering about the lag with a gt 3071.I think that with IE rods i am OK with the torque from a gt3071.Is that right?

[Maverick]

yes

[sylvios]

Any propositions about cast manifolds?
I am thinking of a gt3071 internal west gated.

SPA if you want room to put a filter or intake. But it does have a few small issues you will have to deal with.

[sylvios]

Do you think that i will need something else to run a gt3071?

[Papachristou]

how much difference is there between the 3071 and 3076?

More air flow in the higher rpms, this is why a built large port head is needed to take advantage of that extra air.

I'd rather see some dynojet #'s from you Mike

GT3071R 63ar, good spool, great turbo for a good mix of drivability and some racing
