KA-T turbo kit!?

[skuurtin s13]

okay so im lookin to turbo my ka and ive already done a compression test and results came up with the the highest being 175 and lowest being 165. now that ive been talked into persuaded by research im most likely going to peice one together slowly using the jgs starter kit w/turbo and wastegate. any one go down this road?

http://cgi.ebay.com/ebaymotors...ories

also im short on money and selling my jetta for around a thousand and dont want a huge a turbo just something to scare the local ricers

never buy ebay turbo

[skuurtin s13]

well i know everything but the turbo is what i hear is fine for small amounts of boost, im talking like 7psi

[zzzackkk]

Turboing your car with no tune?

In my honest opinion, you'd just blend in with the ricers. Save up and do it right the first time. Do some research and get quality parts you actually know about. Good luck either way though.

[skuurtin s13]

id obviously tune it

[gotchu]

its up to you but if i were you..save up more and just wait and buy a real good turbo kit not these ebay knockoffs that will last few months ..itd be better in the long run..

[skuurtin s13]

ok what route would you suggest me going in, thanks for the input

[gotchu]

what about going the sr20 route?? isnt it cheaper than turboin a ka? sumone correct me on this one..im too shure

you should be able to piece together a complete t25 setup for around that price. give or take a few hundred.

no.....for the cost of an sr you can boost the ka, and have more torque.

Read.

[spooled240]

sr swaps are like 2000+ dollars swapped in...and every time i read about the swap from ppl who have done them they say that it's always more than you think it's gonna be.

a ka-t setup can be pieced together for pretty cheap..even cheaper if you do your own work and custom work.

[Dire91]

I like this thread seeing that I have the same idea. You'll need a nice tuning system, I was suggested the AEM F/IC. The JGS has a paragraph on everything you need. My question is are ebay FMIC's any good?

[Chris28]

Yes, the ebay fmic's are good. I suggest the JDM Sport kit, it includes piping and fits perfectly.

All this has been stated in the thread I linked to however. Read that and you will truly master the technique of acquiring a boosted KA on the cheap.

I been planning and changing my KA-T plans for a little over a year now. I am going with a T25 and my plan is to have it look like a KA24DET that was turbo from the factory. As of right now the only item I have in debate is the intercooler (OEM SR20 sidemount, frontmount, or midmount). The only items that have stayed constant in my set up is Walbro fuel pump, the gauges, wideband, turbo selection, turbo timer, and something else i cant remember off the top of my head right now.

IMHO the t25 turbo is to small for the ka, if your lookin for basic turbo kit then yes. But if your lookin for real power somethen over 300 then i would go with a bigger turbo maybe a t4 setup or somethen. Now dont get me wrong the t25 has a fast spool but as far as delivering good power it kinda lacks there. Where you might have to use 20psi to get 350 i would only have to use MAYBE 12- 15.

Unless your going over 10 psi you dont need the walbro.

But you will have to use some kind of fuel management, im using the emanage, imo it work good i just got to get the harness connector #2. but if your lookin for over 300 whp its recommended to do a rom tune to be safe.

Me personally im staying at 7 psi until i get a rom tune or jwt i want safe reliable power.

Perfect turbo setup for u OP would be to get a t28 from an s14 or s15. Then piece together the rest of the kit using a decent manifold, outlet pipe and downpipe. The T25's downfall is that it is journal bearing and after raising the boost to 12-15 lbs, it wont last very long...

[skuurtin s13]

ok thanks for all the help, i have a 91 240 hatch would a s14/s15 t28 turbo fit in my car. if so thats the route im thinking with an ebay fmic kit

[blacksrjdm]

Yes, the t28 will work the same as the t25 same flanges...

[Gcustoms]

Use greddy's ka24de kit (s14) it comes with ur computer, injectors, hardware etc. The only thing you need to get is the intercooler. Possibly Bosch fuel pump. It's pricey but from what I've seen worth it.

[skuurtin s13]

so i can pretty much get the setup out of a stock sr, im not trying to get a lot of boost from it only like 7 psi so its reliable

why would a t28 be the best for him if he has a cylinder running at 165, thats acceptable but we all know once turbocharging an engine the previous problems only become multiplied... the good thing about a t25 is their easy to replace and there is no necessity to running coolant lines

in my opinion, you should just get a t25, 370cc injectors, n60 maf, and whatever intercooler you want and there you go... with the t25 on stock internals at 7psi youll be pushin 200hp at least to the wheels probably more... then you can always up the boost to 11 or so...

You cant add all that stuff without a tune!!

all i would need was what you stated plus a fmic/intercooler and id be good? what about a tune?

I only say that the T28 is a better option because my SR used to go through some T25's. But my S15 T28 lasted for the year and a half I had it installed at 15lbs, and is still running strong on my friends KA-T at 12 lbs. And the KA-T spools so fast and is very reliable. But, if you would like to put an inferior turbo on, then to each his own. You may not have to run coolant lines for the T25, but IMO the T28 is just an all around better turbo.

The greddy kit is a piece of crap, or atleast overpriced at that.

But if your lookin for real power somethen over 300 then i would go with a bigger turbo maybe a t4 setup or somethen. Now dont get me wrong the t25 has a fast spool but as far as delivering good power it kinda lacks there. Where you might have to use 20psi to get 350 i would only have to use MAYBE 12- 15.

T25 is a little small for the KA yes. But I'm going to be running an FMU so you don't really want to push it past 7-8 psi with that set up. Should be fine. Also I plan to run water injection and cams, etc. I hope to get 250 at the wheels (maybe not at first but I will try to get a little more power out of it after). 300hp would be nice, but I just don't see the need for it at all. T4 is way to big, all your doing is adding more lag. The best turbo is gonna be a T3/T4 (t3 flanged btw for those of you that don't know). It will spool very quick, and give you a great power band. Should support around 450 or more. If you want the 500+ range your gonna want the T4 but expect much more lag.

I honeslty wouldn't boost a T25 or T28 past 11psi, after that it is extremely uneffective and turns into a heat pump. About the walbro...If I require more fuel I would play it safe and upgrade the pump. It is cheep and it is better to be safe than sorry. Yes the stock pump can survive up to 250hp MAYBE, but why risk it?

Yes you don't have to run coolant lines, but why wouldn't you? they are there so you might as well run them. If you tap the water lines in the intake manifold you can run hard lines to it. Cooler turbo, cooler air, and your heater should heat up quicker too (nice for winter). Water cooled and a turbo timer = longer lasting turbo.

Also I don't plan on getting a tune. There is no need. 7:1 FMU with timing retard should work fine. But I plan to add water injection too, so I dont know i i will up the boost or take off the timing retard, i haven't decited. With such a mild set up a rom or ECu tune is not required.

Just do more reading over in the KA-T section. Everything I have learnt I read over there. Just READ READ READ. Then ask questions. Almost every question you have has already been answered. So just troll over there for several weeks or longer and you will have a better idea of what you are doing.

would an intercooler be a must for this setup?t25 and t28
