what turbo should i get.

GT-35 or TD06? both high mounted, externaly gated and made for about 600hp. BUT GT-35 is top end power and TD06 is low/medium range power.l not sure on the price for TD06 but i got a rough estimate on the GT-35 ($3000 with gate and manifold) + about $1k for injectors.

discuss.

also open to any other turbos u guys think would be good for a rb25.

I've heard good things about the GT-RS.
The question you need to answer is what are you using the car for? Drag racing? Then you want heaps of power up high, so the GT-35 is for you. If you want the power right through the rev range, drifting/curcuit racing, then the TD-06 is probably the better choice.
I'd rather minimize lag. You use more petrol, but it's more fun!

Depends on what you want from your car and if you plan to do any future mods.

One question is your motor stock or have you done any motor work to it?

One thing you have to remember torque is what makes the difference.

Id have to go with the TD06 and get a set of cams to suit the turbo to maximize
the low to mid range gains.

go the 35, thats what im getting for mine,
it may be a little laggy but then again power is only a clutch kick away

i hate lag but i love power.. wonder how much i can get it for.... supose it will have to wait if i get this sky80.
