I am considering purchasing a new turbo.

Just wondering what you guys think would be the best for the 2.0L. I am looking for something to spool fast and support 300-350WHP without dieing in the Higher RPMS

Turbo's I am considering

Garrett T3/T4 57 Trim
Compressor:
Trim: 57
A/R: 0.60

Turbine:
A/R: 0.48
Corrected Air Flow: 50 lbs/min

Garrett T3/T4 50 Trim
Compressor:
Trim: 50
A/R: 0.60

Turbine:
A/R: 0.48
Corrected Air Flow: 46 lbs/min

Remember I am looking for FAST spool time but I dont want the turbo choking at high rpms. Is the .48 to small? I dont really want to to go with .63 because the more lag.

Whats your thoughts?

 

Every single map you would ever want

Look there... u can find which has the best efficiency for your needs. wink1.gif


I would suggest the GT28RS... ball barring and will hold your HP needs, but its pricy.

 

Yup just like 01importshark jsut said BB Turbos are the way to go man.......
I just picked up a Garrett GT30 Turbo for my next turbo project fing02.gif

But if you dont want to spend all that cash then i would defently go with the
Garrett T3/T4 57 Trim BUT get a Hot side of .63 Hot and .60 cold liek i have.........
Yes the .48 hot side might spool up 300-400 Rpms faster but the .63 hot would be more efficent essicially since you have the same Turbo as i have now Super60 and this thing spools up to fast that i have NO traction in 1st or second in the low rpms...Tires JUST SCREAM,which sucks for traction..........
Trust me man i BIT of Lag is OK ..........................

We just about have the same HP numbers so you know what im talking about

The .63 hotside will help out by giving a Bit more lag which is better in the low end bro.......... fing02.gif fing02.gif
Hope this helps!

 

Thanks for the responses.

There are alot more turbo guys on the fourm but yet only 2 of them respond?

WHATS EVERYONES OPINION ON THE BEST SIZED TURBO FOR THE 2.0L. FOR FASTEST SPOOL AND 300 WHP RANGE

 

You got the maps, you can figure it out yourself. Pick any good book on turbocharging and it will explain how to plot the map with your engine. If money isn't an issue, then a ball bearing turbo is the way to go.

2UNIQ: lag is good in certain situations, but your problem is more with the first gear. Why don't you get a dual-stage boost controller, activated by a switch, and wire the switch to the first gear in some way? That way, you would just have say ~6psi in first gear, and the rest would get full boost.

 

Ball bearing is gay for the low booster.

Unless you think an extra $3-500 is worth getting boost 300prm sooner.

 

low booster? lmao.gif

I am going for 300-350 WHP.

 

im sure he means lower boost under 30psi and 300-350whp is doable with 15-18psi pretty easily. As for why people dont respond because most people dont know how to size a turbo. I know i dont my suggestion is to read corky bell maximum boost it describes exactly how to calculate what turbo would be the best. I would allways suggest going 20% higher than you will ever plan on going due to it will make the turbo last longer and i know i get boost happy somtimes. So basicaly get a turbo sized for around 400-425 max you want the turbo to be going out of its efficency at that point. This would probley be a moderat t3/t4 probley ball bearing to help with spool. Yes you can have a turbo spool to fast as then you lose traction thats where a good stanalone will come in handy as they have traction control built in hell i think the emanage ultimate might even have it. Anyway not alot of people know exactly how to size a turbo some say they do and few actually can hell even full out drag cars are allways tinkering with diffrent turbos trying to squeeze every last bit they can.

 

You won't even be hitting 20psi to get that much power. That's low boost.

Most turbos spool to that in a heartbeat, so like I said, save the hundreds from a ball bearing and put it into something else you'll break at 300whp.
