Your experiences with a t25 or t28 setup.

[turbo_dreams]

Searched briefly within the 20 mins i had at lunch to see how people like their t25 or t28 setups and what kind of numbers they saw at various psi ratings. Just curious to know what i can expect after i complete my ka-t with a t25 or t28. Sorry if it's been covered before, just link me to it and close the threads in that case mods. Thanks

anyone?

A S15 Spec R T28 turbo on a KA makes around 220-240RWHP @ 8psi, depending on the tune. A T03/T04E with a 0.64 AR makes about 10% more power at the same PSI, but boost comes in about 3k @ psi as suppose to almost instant boost. Dont' even bother with a T25 setup on a KA.

I will tell you when I first turbo my car (t25) it was a night and day difference but it quikly felt slow ,,,basicly I got used to it too quik and it didnt feel as fast even if I turned the boost up, when it got to 5k rpms it fell right on its face,since then ive upgrade to a HKS gt25 of an GTR and it feels alot faster plus I hve power all the way to 6k rpms ,at 10psi i made 276tq/269hp now am at 12psi and the turbo feels like it got a few more pounds before it out of steem,,

forgot to add my friend only made 220hp/228tq at 12 psi on the same dyno as me and same mods on a t25!

[nelson8708]

mine served me well. Boosted for a year and a half on it. Defintally made a night and day difference. It was great for sliding when ever you want. No matter what rpm i could see boost. No lag for the t2 turbo's. If i were you i would look for a used t28 or just go with a t3.

[turbo_dreams]

thanks alot people...it's making me stray from the t2's now, i'll look into to3/04's now, Any 1 else?

[Garrett0x]

Pretty good numbers are obtainable out of the T28. So I wouldnt discount all T2's

[taco_401]

i just got my set up and its a t 25 and i already want to upgrade go with a t28 or t3 dont make the same mastake i did

[Zippy69]

a t25 is a good first turbo. It will make good power on a ka. Of course you will want more, thats what it is all about.Would I build a weekend racer with a t25? No, I would go with a t3/t4 set up.But for pure fun in a daily driver, a t25 is a blast on an otherwise stock motor. Almost instant boost that pulls hard all through a nice power band for the street. Yes it will poop out at 6krpm, but from 2k on up it pulls hard. A t25 set up is cheap, so you save some money and when you want to upgrade, you can go with a t28. A simple bolt on. Or you can swap manifolds and move to a t3/t4.If you have the money to go t3/t4, then go with that. But if you are low on funds look into a t25 set up. I have friends with sr's that will keep their t25 set up forever, then some that swapped turbos before they swapped their engines.Up to you holmes.

[brunswick240]

Couldn't agree more ^

The t25 setup is definately the budget route, a way to just taste boost and thats it, taste it. But what zippy said is so true you can easily upgrade it to a t28 or something bigger like a gt2871r as a simple bolt on. So the next question to ask yourself is how much money do you want to spend on your turbo setup right now and how quickly do you want boost (meaning saving up for a t25 setup or a t3t4 setup).

[WDRacing]

If your goals are low and you are on a budget, there is no denying the T2 route is a pretty fun option. But if you want to eventually run more boost...which imo is a certainty, you should steer clear of the T2 type of turbo. Since you'll need a completely new setup to swap over to a real turbo.

If you want no lag and room to grow to 400ish whp, then a T3/TO4E with a .48 AR hotside is the only way to go.

I will say this though, the EBay SSAC bottom mount mani's have been doing very well as of late.

WD, now my t25 is crying. You don't have to hit to hurt.

I made 219 RWHP with a redtop t25 just today and 280lb ft torque to the crank on a dyno dynamic using a afc neo. and still running rich at some point if i fix this then i'd be able to make over 230+rwhp. also with stock waste gate so i wouldnt diss the t25.

@ how many psi was this power made at?

[240sxvaj]

the guy at the shop told me 6 PSI

just today i burn a all stock SRT-4 on 3000 RPM rolling on 2nd gear took him pretty far (just thought you might wanna know )

My T28 gets me consistent 12.5ish second passes at the strip at around 110-115mph with street tires.

But there are sometimes I want to just mash the throttle and feel my colon invert....

am I gay?

12.5 on just a t28? no other work done? gt2871r or just a sr20 t28? That's VERY impressive...you think being an average driver with a t25 @ say 12 lb's would send me in low 13's (street tires)? if a t25 alone can't get me into the 13.7's n lower then i don't think i'll bother with them, the reason being is, i like staying next to stock evos being most my friends have them =)

GT2860RS .86ar Hot/Turbine and .60ar Cold/Compressor

My car is ECU tuned, with an SAFC for fine tuning. Walbro, 740cc Injectors, build motor(rods, pistons, arp, etc)

T3/T4 will yield more power in the long run. The T25/28 turbos are fun on the street, and can be pretty sweet on a stock engine with a good tune.

It's all about what flavor you like.

great, thought it was a stock ka on a t28...so i guess there goes my hopes for mid 13 sec passes on just a t25.

[eazye2000]

Well, on a stock KA, you're messing with 9:1 or more compression. Which will yield more power per PSI due to the factory cylinder compression. But then you have to finagle with the timing a bit more since it gets kinda hairy.But you should haul some balls with a normal T25. I've never done it personally, but I imagine it will be faster than stock..

Fast as in mid 13's fast?

[eazye2000]

I can't guarantee anything bro. A lot of factors come down to the driver when drag racing.I would say do it if you don't have the money to go with a good T3/T4. Just my opinion.
