I just bought a 20B and I want to know what type of modifications can I do to get the max performance from my engine. Thanks.

 

bang for buck im finding the gt42 to be nice.

max performance as in 1100rwhp?

numbers in the 600's.. t72 or t76 should get you there at about 20psi

mods... custom everything (mounts and manifold you can buy)

 

There's no "best turbo" for all setups, its completely application specific. A turbo that's properly sized for a drag car would likely be inappropriate for a circuit car.

That said, what are you building the car for?

 

Where's the triple turbo option!!?!?!?

How about Pettit's modified stockers with increased flow by 20%? You can stay sequential if you want and don't need a special manifold. Looking at this option for our street 7 but would like to know opinions. Has anybody but Pettit tried this, they advertise 550HP!

I've always wondered if BNR could do a stange 3 on teh stock 20b turbos, that would be a nice all around setup

 

Could you break down the BNR. Stage 3 who, a little more info please. I'm not aginst going into new territory, but would want to move with the informed on any new project.

You can't stay sequential without the stock ECU.

BNR can upgrade stock 20B turbos.

 

anyone want an secon ht15? because im getting rid of my stock twins. dont laugh i was looking into making a dual turbo mx-3 v6 (its a 1.8liter v6 motor) Too much hassel for about 400whp so im getting rid of them and had the thought of twin ht15's as an option.

 

I would recommend the T76 myself
