I have a 2001 civic ex 4 door. Which turbo should I get? http://www.turbocalculator.com/sale-garrett.php
I heard the Garrett T3/T04E Hybrid Turbos are the best. What is the difference? I dont want to blow up my engine, I plan on running around 6 psi. Also, what compressor trim should I get? What is the difference? Thanks.

first start to understand how a turbo works and what all is needed for a complete installation, that will help u out ALOT before u actually buy the turbo

A T3/T03E will be WAY too big if you are running 6lb. A T25 would be more suitable.

I was thinking either the T3 Super60 with the .63 hot side or the T3/T04 .50 cold side .63 hot side and a 57 trim wheel ... looking for about 220 whp ...

lookin for a new clutch too?

for clutch im getting the exedy 3-puck with prolite flywheel.

you can get 220whp out of a much smaller turbo that will spool quicker

word. I say get yourself a T28 or T25. The t3/t4 is best for higher boost applications. It wouldn't be worth the lag time.

T25, T28, or T3 Super 60 a/r .48

You failed to mention at higher boost levels for that T25. That T25 will have push about 10-12 PSI to see that power at the wheels. While a T3, can see that power at 8-10 PSI, then a T3/T4 at say 6-8 PSI.

It's all about the flow rates of the turbo. 8 PSI on a T25 doesn't equal, 8 PSI on a T3, doesn't 8 PSI on a T3/T4. People need to get their facts straight.

Not to mention your power band is going to suffer past 4500 RPMS with that T25. (great low-mid)

The T3 will power straight through redline from 3K RPMS (great mid-top end)

The T3/T4 will power straight through redline from 3500 RPMS (great top end)

T28 will see power all the way till redline also....

 
Rep Power: 360

very true. i love my t28bb. pulls all the way to redline. cant complain execpt for the blown HG. lol. o well its getting fixed monday.

ill have a dyno sheet by mid week next week.

same here, on thursday Ill be getting tuned. thats when my appointment is, so well see what a T25 does. Since nobody likes to post dynos. If I dont scan it, Ill at least type it all up so people can say, LIAR, lol.

Just stay away from Greddy turbos if your going custom

 
Rep Power: 0

true but from EVERYBODY I have talked to running boost, you rarely end up at the power level you originally were going for ... Most people say, "I never run more than 8lbs of boost" then 5 months later you hear they were at the track boosting 11 lbs... Plus with a built motor, a bit larger of a turbo should give me a little more flexibility in the future ... I'm thinking the T3 Super60 may be the way...

 
Rep Power: 360

well i am running 5-6psi right now, but i am gettng a new hg and head studs and e-manage...i wanna turn the boost up but i wanna get a clutch first..so im going to have them tune my car at 6psi. then hopefully by next month ill have a new clutch.ill scan thou so poeple can see.

Sort of. At 8psi a motor will flow the same amount of air regardless of which turbo is on the car. The reason for the powerband differences are because of efficiencies and other factors.

 
Rep Power: 0

Different amounts of airflow produced by the turbo are what causes the variance in power. CFM all the way.

 
Rep Power: 0

CFM is a direct relation to pressure ratio across a medium, in this case, the motor itself. If pressure is raised a certain amount a set amount of air will flow.

when i said a smaller turbo, i never mentioned the t25 or the t28, but i dont know where you are getting your info about the t25 loosing power after 4500 rpm...think, why would they use that turbo on factory cars if it isnt going to hold boost throughout the power band...the t28 reaches full boost before 3000rpm, and is very capable of holding boost well past the d17 rev limit....
in my OPINION i think that the t25/t28 would be the best turbo for ours cars if block/head or not built...dont get me wrong, i am not downing the t3 or the t3t04e, i have had both on my car, but many times i had wished that i had a smaller turbo that made boost sooner, on place being the track....

so what if a person was looking for 250 whp but wanted to keep the spool time low ...

 
Rep Power: 0

the t28 that i am looking at getting powered Forced Performance 2Gen Awd to an 11.8 @119mph in the 1/4....i bet he was making a lot more than 250whp

From experience, dyno graphs and such.

Get a larger wastegate. It won't drop off as bad.

ok So from what I gather the t25 or t 28 is the best turbos for a stock d17. but is it a turbo that can grow with the motor , say down the road doing an engine swap ?

 
Rep Power: 0

Well, if you swap to a K20 not many turbos will work for both well. A full-race kit for the K20s has a T3/T67 and that would be HUGE for a D17, so, your SOL in that regard.

 
Rep Power: 259

So the the t25 or t28 at 5-6 psi is a safe start with most stock parts? and is upgrading the clutch the main replacement part to turn it up to 8-10 psi safely or are there other parts that should be upgraded too? BTW Thanks 4dr for a very straight answer, appreciate it..
