I want suggestions on this setup i'm thinking about doing.

Okay, so i fully built my ka this year, and after the engine is fully broken in by the end of this season, i'm thinking about dong something, i don't know, different i guess.

So i'm thinking taking my ka, making it top mount, with a T28 sized turbo(15psi?), 810cc injectors, v mount intercooler / radiator setup, and a pathfinder(?) supercharger.

Here are the two images that gave me this idea.

Yes, i think i might even use a 4in intercooler core. lol

It seems that you're looking at doing what is known as "twin-charging" am I right here?

Running BOTH a supercharger and a turbocharger is relatively inefficient. It's expensive, complex, and produces monstrous amounts of heat..

Point of running the vmount rad intercooler setup with a vented hood. Yes this would be consider twin charging, and with a twin charge the powerband for drifting is near perfect, for a ka it almost isn't a need, because they have the tq, but non the less you can never have enough.

I also currently run both an oil and ps coolers, so i have taken heat into consideration.

i would think the t2 flange would be a little small for your goals. i wouldnt see the need for 810cc injectors, even though they wouldnt hurt anything. i think a t3 or t4 turbine housing would be a lot more efficient

I'm unfamiliar with the T3/t4 turbo sizes, so i was just stating I would use a turbo that would produce similar specs as lets say an s14/s15 t28. and I figured 810cc injectors because I would need the extra fuel to run both a super charger and a turbo charger.

the t28 has a small inlet flange. making back pressure in the engine. the t3 is bigger and yet again the t4 is larger than that. sounds like you dont quite have the knowledge to complete this build. not trying to be rude. just sounds like you need to do a little research first.

why not just super charge it?

the cost of this build is gonna be huge btw

probably a better idea to just swap an ls1 or something

not reallys. my ka is already built(ie supertech valve train oversized valves bored .20 over 8:6:1 comp eagle rods etc.)

I'm just looking for s*** and giggles on next year. I like to think outside the box. and i've always been happy with my ka(blahblahblah fanboy) i own 2 sr20s.

well.....lets start with the charger first.....superchargers may deliver instant boost...but only to a certian rpm range...then they fall flat on there face and actually produce a restriction in air flow with a duel set up like this......imho....i would duel turbo before ever considering this set up.....there is another route you may not have thought of for belt driven boost...the Procharger....basicly a gear driven or belt driven turbo bro...insta spool...and comes in many sizes...one great benifit to the procharger....cool air charge!..just an idea for you to ponder....

t3...it seems you have big plans for your future driving days at the track...good word of advice...plan your car to be upgradeable......as you grow in driving skill, you will soon find your self out growing your power ...give your self some growing space by reaserching different flanges before you settle with just a basic T-3 flange..you may want to change it later..and it will cost you again if you do..

welp..good luck man..what ever you decide to do.

I didn't know it actually restricts air flow, I will look into it some more and the procharger does seem like a good idea. And changing flanges isn't too hard, being able to weld helps a lot in that. lol

^ I was just about to say that. Just twin turbo charge it. No one's ever done it before.. or at least that I've seen. It might be inefficient, but it's an interesting concept none the less.

It's not really inefficient, but more not needed, but could be done none the less.

dont twin turbo (it would be cool, but has been done on both the single and twin cam) the twin charge is a cool setup. i have never seen it done on a ka (not saying it hasnt been done) but you will likely be the first and if not probably the second. if your a welder, and you have the cash flow then im sure you can do it. just research before you get stuck on a t2 flange lol and run a crap ton of boost

run it like this Image

so you get the twinscrew type supercharger and the flow of the turbo charger
