my friend has a sr20det.. the stock turbo is a t25 and he wants to get a bigger turbo.. one with a max hp of around 400 .. any suggestions? preferably ones around or under $700.. sr20det is a 2L .. his is fully ported and polished.. nice tubing.. big fmic ..

thanks for any help

also.. what size injectors should he get that would support 400hp? or just to be safe (or for future upgrades) what would work for like 450?

just looking real quick .. theres 550cc, 600cc, 650cc etc etc

Unless it's used I don't think you're going to find a good turbo for under 700 bucks.
i got a gt28r for just over 700, i believe it was around 750, and i would consider it a "good turbo"...

sorry to say man, but i can't think of a turbo that retails under 700 and would be able to generate 400hp without a slew of good supporting mods.

in regards to the injector question, coming from the dsm camp don't even think about 550's. you would most likley max the out around the 325-350whp mark. for 400whp i would look into a set of at least 720's. with those you should be able to make the power that you are looking for without having to run the injectors at some insane duty cycle to get there.

yes i was thinking about a t3/t4 or a t4 ... THOSE can be had for cheaper .. gt28rs and gt30 are $1200.. i already said .. he isnt gonna spend that much

like this but a bit bigger http://www.atpturbo.com/Merchant2/mercha...tegory_Code=TBN

either a new turbo like that.. or i told him he should just buy some more parts.. because if he gets a t3/t4 he has to get a different manifold right? for a t3 flange.. he has a t25 now.. also possibly a different downpipe

he could get a new turbo or for cheaper get hks cams, hks exhaust manifold, intake manifold

you can go with a regular t28 with a set of 440 cc injectors and be just fine... my friend just boosted his n/a sr20 with the gti-R stock turbo kit, with 9 psi to it and a top mount, 370 cc injectors hes looking at 265 whp untuned. put a t28 on there with a 3 inch exhaust, front mount and about 15 psi with a set of 440cc injectors with a jwt ecu and i see no problems in achieving the ~400 mark

hmm really? i think it has like 440 stock and those max out around 250.. he'll prob just get some 660 or something

hows this turbo sound?

t3/t4 turbonetics .63 a/r exhaust .50 compressor 57 trim compressor wheel

its good for more like over 450whp right?

stock injectors in a DET i think are 370's or slightly lower.. 440's should get the job done. the t3/t4 is nice and will support the power desired but unless the fins are clipped id thikn itd take alot longer to build boost as compared to the t28

yeah its a 4 cyl

with that tool it looks like this

450bhp > 707cc so .. 700cc
400bhp > 629cc so .. 650cc
350bhp > 550cc so .. 550cc

probably get 700s so he has injectors that can handle the max of his turbo

um....sr20det wants to over 400hp is an easy mission,you can try HKS GT3037 or GT2835R series.Even try T04e or T04r
is also a good way.And I want to notice you that don't increase too much psi,otherwise the engine will....


sorry...i just imagine....
