Bigger turbo
 

I currently have a bnr s4 but I’m looking to upgrade I’ve been looking at pt6266 or a gta 3071 gen 2s I have a gen 1 ms3

isn't the garret 3071 around the same size as the s4? the 6266 would be a definite step up in power.

do you have a specific goal in mind?

also you may want an extra fueling source and possibly build the engine if you are going for a turbo that big

I want about 600whp with room for growth I have been leaning towards the 6266 a lot cuz fckn racecar and i already have planned on getting all supporting mods I just want a recommendation for about a 750-800 MAX build

Don't feed the trolls.

Unless you're willing to commit to a lot of supporting mods and a built motor, the low 400 range is a much more realistic goal.

Good luck with FWD traction and drive train reliability. You’ll have to upgrade a lot of things besides the engine. But, because racecar . . . shit breaks, wallet must be fat, and who cares about traction, right?

this may be a troll...

but if you're actually serious about doing this, plan at least 10k for built engine, extra fueling source, manifolds, etc....

plus, you would likely want upgraded brakes, suspension, etc... so plan another 3k for that stuff.
