Best Turbo Upgrade

[Suprasath]

Im trying to buy a good, reliable turbo that spools up fast and keeps going till redline. Something that I can build 25psi with. I saw bunch of ct 26 upgrade, T3/T4, name brand turbos like hks and greddy. I want everyone's opinion on this but mainly looking for the guys that has experienced it out there. I just want to pay for somthing once and let it last a while than break down in 8months down the road. Something that i can look at and say "ye thats money well spent".

Hopin to hear from you folks soon.

it all depends on your goals for the car.
you can never go wrong with a .57 trim ct-26 if you want to make 350-400 hp. i have loved mine the whole time i've had it.
i will soon be upgrading to something a little larger though.

do you want quick spooling, or a little lag?
do you have the necessary upgrades for the rest of the car?

the BOSS BB turbos or the garrett GT35R will do that for you but once again man it all depends on how much loot you willing to part with...

 

[figgie]

no such thing as best....

there is the right part for the task at hand.. which you did not mention what that would be.

25psi means nothing.

i love my dbb boss series comp turbo. its big, spools fast, and moves a lot of air.
i recommend it.

25psi means nothing.

It's bigger than 24 and smaller than 26

I hate the turbo lag. I rebuilt the engine about 2 months ago. So its healthy but compression ishigher than 160psi all cylinders. HKS MHG and arp studs are done for sure. IM running the maft pro in speed density mode. I got the walboro 255 pump. IM only looking for 400whp, since my internals are all stock. Intercooler is done. 3' exhaust from turbo elbow is down also. For the kind of power im looking for i dont knw if i would need bigger injectors and adjusable fuel pressure regulator. My budget on a turbo is about $1500 max. I just want somthing that spools up at about 3500rpm atleast. But something that can last.

Just wondering how lon you guys had your upgraded turbos?

get a 57trim ct, 550cc injectors, wide band and afpr.

6,000 miles on sp61gt, full boost in the range of 3500-4000rpm and positive boost in the low 2300rpm range. Hits pretty hard at 16psi.
25psi on pump? race gas? meth?

yup thats what i was thinking..but if i read your post right you got the stock turbo elbow?? pretty sure thats a big downfall.

i've got the above,maft spd/dens, 3inch turbo down then to 2 3/4 back no cat, and i get full boost 7.5-8.5PSI at about 2700rpm..na-t of course and that turbo is about half your budget. boost controller in and 13psi here i come in febuary when i'm back in vancouver.

edit: and thats about 3/4throttle-2.8volts on tps...another short coming of the na-t to be fixed in febuary

wow now were talking. I need everyone's input on this because this will help many of us out there. I have to admit, I've been in a lot of forums but this is one of the best forums ever.

how quick do you spool up and how long does it last rpm wise? How long have you had this upgrade?

Any of the CT upgrades are still going to fall off on the top end as you outflow the exhaust turbine...

"Best" is a relative term. For that power level the TD06 upgrade is quite nice, but expensive.

greddy seems like they know whats their doing but the price tag is high.

theres a sticky in the ge section, but you allready got the gte block so.. i'll be running the same setup when this eng packs it in. oh my turbo does only have 2500kms on it, 1500km 1 day, freeway not boosting. other 1000 very hard lol

 

[aye mate]

SP61, sounds like a good choice for you. I made 430 at 17psi.

 

[hvyman]

i have the 57 spools really quick. very nice upgrade. the sp61gt very nice too bolts right up.

 

[wardog]

I would say go with a ct26/ 60 trim note the 60-1, get some 550s, afpr, supporting mods. Take a look at what a ct26/ 60 trim can do at 18psi
