Building a KA24DE

[SlidnSideways]

Im thinking about building a KA does anybody know what all i would need as well as good brands to go with and what type of times i would be running... Im hoping for low 13's to high 12's with a built ka24de with something like a little t028 turbo. You think it will do it?

To run high 12's you just need a good turbo kit and some decent tuning. No need to even touch the internals of the engine. A T28 however is far to small of a turbo to even consider making good power. I'd suggest a T3/TO4E in 50 Trim with a .63 AR ex housing. With that turbo and fuel/timing management you'll be golden.

What do you want to do for engine managment? Or do you have any idea's. You might want to read through the forums for awhile before you get to involved....there is alot of good info to be found here.

If high 12's is all you are looking for im pretty sure a z31 turbo will get you there, simple fuel management aswell. But let me warn you, everyone gets used to their setups and always end up wanting more. In that case the turbo WD mentioned would let your turbo kit grow into a more powerfull car than you may want today.

I have the T3/TO4E on my car right now and it spools up very fast. I have no complaints at all, plus she's good for about 25psi before she becomes a total heat pump.

Yup, its the same turbo I have on my car and I love it. Just giving him some options. Not everyone is power hungry like you, me, and some of the members on this board.

Psssht, they haven't tipped the pedal on a boosted car yet then....Pure ecstacy!!!! Worse the Heroin.

[DRIFTEADOR]

since he asked about 12's....what size drags/slicks do you +300hp guys run at the track?

Costs more too, terrible addiction it is. As for slicks maybe someone else will chime in, I run 275's in the rear so traction isnt really a problem.

Well a friend of mine...Not really toooo familiar with KA's but pretty good with his stuff told me a built KA with a smaller type turbo would be good for 13's...problem is my brother has a fully built sr20 that hes running a t3t4 turbo on so hes well below 13's. Not that im trying to keep up with him but hell i dont wanna be left in the dust ya know? I figure if i can break 12's ill be happy and maybe ill add stuff later as well

If you don't want to go through the trouble of fabricating your own kit there are some companies that sell KA turbo kits:

IAP This is where I'm getting my kit from. for about 3k$ I should be looking at around 200-220rwhp (with supporting mods)

Boost Designs 1,999$ claims of 232 rwhp @ 8psi daily driven and reliable.

imho you would be HARD pressed to piece together a turbo kit w/ the quality of parts and A NEW turbo at the price of either of those kits. might as well go with a proven route and save yourself the frustration/headache of having fitment issues and replacement issues. I'm not trying to be derogative or discourage you if you want to piece together your own kit I'm just saying, it's not for everyone.

(edit) anyone want to chime in on this. I don't think BY ANY MEANS you need a 'built' block to run low 13's. 230 rwhp should be good for mid/high 13's then some fuel mgmt/tuning and you can have 250-270 rwhp to see low 13's maybe high 12's? Does that sound about right or am I getting a bit over-enthusiastic. keep in mind a KA motor is going to be producing a boat-load more torque than an SR counterpart w/ same hp (/edit)

The thing is...and i guess it probably woulda helped out to mention this first (sorry)...I have a sohc KA24E and its got 146k miles on it (not the greatest condition)... So that would need built... A buddy of mine just opened a shop where he is completly stripping and re-working a 240 and hes throwing in an rb26 and said i could take the KA24DE off of his hands...that motor definatly needs rebuilt so either way i would need to rebuild. They have plenty of turbos ( t28 i know for sure but maybe some bigger) just laying around the shop that he said he would be happy to let me steal too so im not too sure what kind of turbo will be put on initially. I have connections for a machine shop that can throw everything together so im basically looking at what im going to need to order as far as building the engine and turbocharging it.

both of those sites sell kits for the Ka24E motor. I have that motor too and what I'm planning on doing is getting the kit installed, supporting mods installed, then getting a built KA24DE block from Boost designs. it comes WITH the manifold so I dont have to worry about that. So I get power to play with now and time to save money so I can get serious. Just a suggestion. if you want to build your own motor both those sites sell their turbo manifolds seperately so you could turbo your SOHC and then do a DOHC motor swap and have everything bolt up with the exception of the exhaust manifold.

i was going to build the dohc motor since im getting it for free along with the turbo that way my car wont have nearly as much down time being as its my daily driver. I know of a machine shop that will install all of the parts (pistons, rods, etc) for very cheap. Im just really at a fork in the road as to wether or not i leave the ecu or work with some kind of engine management? I really just need to know what im messing with before i order anything.
