is my turbo too small Options

[RUNNIN-LOW]

well ive ask this once i think already but is my turbo to small. i have a t-25 and yeah it smaller then a t3 also im boosting 7psi. but i feel no boost on high gear. just first and second. the weired thing is that i cant even pill out on 2nd. WHAT SHOULD I DO!!should i just add abigger turbo.ive been asking around and have sources to get a ct26 but im still thinking that i might have some power hidden in my t-25

[Blakout16]

im an n/a 7afe and i can peel out in 2nd... lol sad.

You should run a T3 turbo with 9 - 10 lbs psi. The T25 is pretty puny, but props to you on the engine work.

[RUNNIN-LOW]

yeah how sad is that huh.. but yeah im stuck on what to do. thanks vangsta_celica

i am buting a TSI turbo kit some time this week. it comes wit the T25 turbo, should i save the time and order a bigger turbo at the same time and then just sell the T25 on ebay??

I'm guessing you just threw a turbo on, didn't do anything with your intake, fuel, exaust, or cams. It's an airflow problem, hence the "no kick in the arse" feel in high gear

StreetRacing10PSI well the t-25 has alot of power. but what ive heard is that its too small for such a large motor. i recommed you just add a bigger turbo. just cause i know youll get boost addicted. i am. well spunky393 i have a warblo 255 fuel, adjustable fuel reg, supra light green injectors, 2bar map, and should be gettting the fmu and a safc. but i still am not feeling boost in high gears i know the 5s doesn't have the best top end but i still want to feel the car pull to top end. tried t put in the t3 turbo last night but it woudn't fit. thats sucked. so put the old t-25 back. jump the boost up to 8psi feels a little stronger but no feeling in 4th or 5th

here is my though your out of the turbos power range on a little t25 on a 2.2L motor you should bump up to a t3 with a 60 tirm

almost all the T3 series is too small for the 5s. IMO if money wasnt an object, i'd go for a T3/To4E hybrid with a 46trim compressor and a .48a/r for the turbine.

in that graph i plotted for 7 and 10 psi...good stuff, and as you turn up the boost it just gets better. i'd definetly sacrifice a little spool time for what that turbo will give ya
::EDIT::: heres a plot of a 60trim T3, just so you guys can see what im talking about, this is the largest compressor in the T3 series.:

as you can see, your almost off the right side in the higher RPMS...anything smaller than a 60 trim T3 and your way off the map by 4500-5k...the exact reason your car falls on its face in the upper rpms, with ubber quick spool, your turbo is too small.
IMO if your going to use a T3 nik is right, go for the 60 trim

there are 60 trim and super 60 trims but i would agree with pressure i would go t3t4 if you can afford it. If you ever wanted to beef up the internals down the road the t3t4 will still work as the t3 60 trim would start to see its limits.

ok guys now i see thanks presure2 and nik i think ill just keep it simple now and just put a ct-26 in..i think ill like it better and plus it a toyota turbo.TRD is my way of a driver!!!haha lol now twin entry or single. thats the question

[presure2]

for the celica you definetly gonna want the twin entry.

[RUNNIN-LOW]

what do you have in yours presure2..so twin i think it is.

[presure2]

the turbo is not in my car ATM, im getting ready to send it to ATS racing for a rebuild and upgrade to a ct-27, but yes, its a twin entry if that is your question
