I suck. Anyone tell me what turbo will boost 6 psi the fastest and most efficiently on a 2 liter four banger?

 

no





It takes a little more info than just that.

 

this will....


j/k, go with a small turbo, a lot of my buddies go with the dsm turbos, they seem to like it. cheap easy and affordable.

 

Hmm... A20A3, stock rebuild (9.1:1 cr). Maybe Stage two regrind cam, what paeco calls their FI cam. Probably go with a custom log manifold. Need more?

on a 2 liter im assuming a b20, a big t3 should do the trick if your planning to rev higher go with a t3/t4.

 

A turbo that flows a hair under 300cfm @ 1.4bar pressure ratio would be a good starting point. From there, check out different compressor maps and find the one that those 2 numbers will be closest to the peak efficiency island on the map.

A20's love boost, 6 psi on a small turbo is ----. After seeing the motor you posted I'd say look into a garrett t3 60 trim or something close. Rpm's limit your topend, so a .48 a/r exhaust housing would reach boost threshold in a timely manner and not choke up at your 6500 redline. Go for around 8psi off of it...you'll love every second once it's tuned.

Sucka Dicka!

 

t3

 

on the focus that is also 2.0, i use the t3 .48/.60 60 trim and it works very good. Stage 1½ even better.

Even faster spoolup?? Go GT2554R BB or maybe twin turbo it with some tiny gt12 turbos!!
