Mild power adder, say you want around 200 rwhp.


Turbo Manifold
Blow Off Valve
Small Intercooler (potentially get away with a side mount)
Turbo T25/T28/14B, etc. Smaller T2 setups. Usually will be internally wastegated.
Downpipe 2.5" is perfectly fine
Replacing the Exhaust is starting to be very necessary at this stage, so I would start to shop for that as well.

Fuel Control
SR 370cc Injectors
Apexi SAFC2
Greddy Emanage
Back off base timing at distributor or MSD BTM

Average: 300 rwhp to 350 rwhp, you have to start to expect a little more lag. This is about the perfect "street car" limit. No race gas, just good honest street car fun that is fully capable of bring home a 12 second timeslip on a good run.

 

Very Mild Build: around 180 rwhp

Turbo Manifold
Blow Off Valve
Turbo (T25)
Downpipe 2.5" is perfectly fine
Pipe to connect turbo to throttle body

Fuel Control:
FMU (not recommended, but doable) Raises fuel pressure per boost to make injectors flow more than normal.
SR 370cc Injectors. These can be found at places found at the bottom)
Apexi SAFC2
Greddy Emanage

maybeim miss informed but y a safc2 and a emanage? im confused

 

theres a guy running a n60 maf sr injectors and everything else stock no tune makin 230whp but the low boost level your going for you can ride on a safc tune

 

let me put it this way, a rebuilt stock ka would be good for low psi turbo (under 8psi). but remember, your set up will only be as reliable as the amount you put into it. i personally have never seen a stock ka turbo last more than about a year on low boost. the more boost you run the sooner it will blow. and they do all blow eventually. save a little more money and so a stock sr that will last forever. my .02

 

thank alot for the input guys!
the thing is, ive also asked this in some ka-t forums, and there have been many people running their stock KAs with just an 8:1 FMU, stock everything, 6psi-7psi boost, etc and theyre setup has lasted so far 2 yrs with no issues...

any way to shed some light on that? or those many people are just REALLY REALLY lucky?

 

they are really really lucky, or don't beat the crap out of their cars like i do. sr's can take a beating, ka's can't. i have worked at xat and enjuku racing so i kinda know what i am talking about. i would go sr, but kat can work as well. just more problematic.
