My motor mods are HS intake

HS headermotorsport 248/248 cam set electric fans star spec crap clutch! ported on exhaust side only to mach the headerVLSD

The car made 161 WHP on the dyno

I can say the car is so damn fun to drive and drifting is a total blast with this amount of power and im very close to building another ka24de for boost.

The only way I would keep my car N/A is if I could get a throttle body set up with a stand alone and high compression but that is money!

well im into autox nto really drag racing so i dont need a million rwhp, but i wanted to up the ponies. and i was going to boost but i know to many people running boost and not alot of N/A... so my ideas were high compression pistons bore out my intake manifold, pulleys, intake, headers, exhaust and all of that that should move me up, maybe at least make 200-250 at the rear wheels....i was also thinking about cams but i dont know a lot about how cams work and such yet, so is there a good cams tech page.

thanks jason

any of the guys on the left are a good place to get ka parts. word is that just getting to 200 horsepower is tough.

hmm well how much hp does the ka come stock and i think if i plan it out right ill be able to get 200 hp... hopefully i bet in the long run it would probably be easier and cheaper and less of a headache to go boost but, well see

I'm running an all motor set up too,and let me tell ya ,to get 200hp out of a ka you are gonna need some money.With all the money you spent on the all motor set up,you could have been boosted and pushed a bunch more ponies out of her.

higher compression cams and throttle bodies plus a stand alone will get you to 200WHP its been done many times on the KA24E.

But who wants to spen that kind of money for 210ish WHP?

I do think the KA24DE would sound very cool with throttle bodies!:cool:

there are a few people putting the DOHC head on an SOHC block to up the compression. kind of a hybrid motor. i dont know if you guys have been following it, but it sounds interesting. very potential hp. doing this puts the compression at 11.7.1. i am not sure if this works, i am still waiting to find out and doing research on it myself. but i want to go all motor, and i think this is a good idea.

i was thinking about doing the dohc heads on the sohc block.. it seems funner to do actually but i have no idea why it would up the compression could some one fill me in on this? like what is the stock compression on each motor and what would the new comrpession adn is it that ka24e has longer cylinder chambers or what? sorry for the newbie questions but i jsut dont understand it. and i know there is a post on here that explains everything but i cant seem to find it . could some one push me int he right direction? thanks

I want to buy a 84 Z22 block and remove the crank out of it and rods and have it custom fitted to a KA24DE block and have the block decked. This would give me a KA22DE with a 90 mil bore and a 92 mil stroke. With the DOHC head good valve train I’m sure it would rev real high! I talked to a machinists and he told me he would have to cut off the fronts of the cranks and swap them and re mill the crank journals to make a lower stroke KA block. I would like to try this as a prototype in NA form with 11.1 pistons and revving to 8 k I wonder where it would peek out too? An Sr is 86 mill 86 bore this motor would be 90 mil 92 stroke

If you want to know all the specifics on a build like that, i can tell you. If you plan to use the ka block, the crank snout will need to be turned down to ka size. The main thrust bearing for the crank needs to be modified. you can either widen the actual main on the block (and use z bearings) or weld up the thrust main on the crank and use the ka bearings. Both of those options are a lot of work. There is a few other things you will want to be aware of, if you want to know email or message me on aim or msn.

Thanks devious I’m sure I will have allot of questions. I have a friend who is a machinist and is an expert on ford block building crank balancing the whole deal. This KA22DE motor has never been built and I plan to do it all motor just to see the out come of a hi reaving KA motor that’s all most square but larger than a SR I think the out come will be surprising and I’m looking forward to an 85k rev limit. If I can work this out NA the next one I build will the for turbo bottom mount and ill be looking for 600HP ;)

PS I found a Z22 block for 150 bucks with a good ole forged crank!

And my friend is about to give me his KA24DE engine so its time to play:ylsuper
