ABY mod

[Keith]

Hi to all,

I'd need an advice as I don't really know where to go.

I have ready to plug this :
RS2 turbo
RS2 exhaust manifold
RS2 green injectors
7A exhaust camshaft

Already mounted :
Forge pop-off
RS2 intercooler

1) How many max HP can we get from an ABY with a 7A exhaust cam without any other engine mod ?
I've head something about 400/420 HP ?

2) Which turbo seems the best to hit de max HP determined in question 1 ?
GT2871RS ?
GT3071 will not be too big ?
I can have an K26/27/29, what do you think of it ? can it bring me to 400/420 HP ?

I don't know if I tune my S2 with all the stuff I have and get something 'round 360 HP or change to another turbo to get the max without changing pistons, rods or anything else !

thanks to all.

Bye,
Keith

Both the 2871 and 3071 will get you 420 bhp.

Go for the 3071 boost quicker than the RS2 turbo.

You'll haev to get it mapped not to push too much boost low down as from the above list your using original rods

thanks,

what about the K26/27/29 ????

is it worth it ? for 400/420 HP ?

Forget the K26/27/29

The 2871 boosts quicker than a K24 and the 3071 just a little later.

The K26/27/29 will be around 4k rpm or later. Why have the extra lag for the same bhp?
