What color are you going to pain the bay are you going to do it yourself or have it profesionaly done. my lude needs a paint job bad but im still trying to deside on what to do.

SlimBB4

thanks!
the bay will be color matched to the car. glacier frost mica from the is250/350.
it will be painted professionally by Superior Auto Body (same shop that painted the rest of the car)

This is going to be amazing! Looking forward to your finished bay, and good luck

keep it 100

Can't wait to see how this turns out, gonna be a monster!!

nice build! I have a 93 prelude with no engine, im probably just doing an h22 build, but maybe later down the road ill do something like this.

I LIKE THE WAY YOU THINK! after finding this thread on the web I HAD TO get an honda tech account! i got a 94 prelude S and im planning out my full build for next summer. I was thinking about swapping my F22 with an H series but after research and my love for the K series i decided to go with a K20..(IDC what anyone else thinks)... I noticed you were going with the Wavetrac LSD. now which one would i get since it is a swap? the one for a 92-96 prelude orrr what??

zuptidi

if you're going K, go k24. dont go with a k20

SlimBB4

thanks! im glad i can help inspire you. I agree with the post above though. if you are going to K-series with a prelude i would go k24. for one the hasport mounts only with a k24 block and k24 tranny but the additional torque available for the k24 will help with the preludes slight weight disadvantage. since the tranny you will be using will be a k24 unit (either 5 speed from the accord or the 6 speed from the tsx) you will need to run whatever lsd you want for that transmission. i went with wavetrac because they offer a great warranty and they are made by the same company that makes quaife but are a little less expensive.

so that everyone knows... the k24/k20 swap is still in effect. i have been patiently waiting for my hybrid racing timing chain tensioner and my modified rbc intake manifold. i just received the tensioner last week so i can finally put the motor together and i should have the manifold sometime this week.

^ you said that like 2 months ago about the manifold hahaha

Your buddy better be done.

SlimBB4

i know... tell me about it.

Im currently researching doing a kswap in my 4th gen prelude. What shift cables and shifter box do you have to use with the tsx 6 speed?

crazydominicanman

Updates on this Zac????

3gpreludetuner

Sick swap bro and props for the good updates and good info. That lude is gonna be a beast for sure. I have a 3rd gen lude but an H22 will work just fine for me. Lol.

SlimBB4

i know that k series throttle cables will be needed and with how the ludes current shift box is i would think that the tsx unit would be needed. i am probably going to purchase the tsx mugen box and make it work. i am probably going to be having Hybrid Racing make me a set of aftermarket shifter cables. my application would be slightly different then yours do to the different locations and lengths necessary for my car being right hand drive. i will give you a for sure as soon as i make the purpose.

there are no real updates with this yet. just saving some money up so i can get the car into the paint booth to have the bay and mugen bumper painted. then i will be able to test fit the motor, which is all back together aside from the oil pan and chain cover. once the motor is in, Xavier from Wireworx will be building my milspec harness and Derek from all in fab will be building my header.

Keep us updated, when finished this thing will be like legendary.

Thanks for the info!!!!! Keep up with the awesome job, cant wait to see this done.

Zac does WireWorx have a website? I have not found one on them?

codyh

He does not. But check out my sig for his info. And my build thread first post for pics of my CUSTOM* harness. Some have said its made of gold. Idk prolly being sarcastic.

SlimBB4

no like cody said. Xavier (the owner and master mind) is a hella cool guy and i believe he is working on a website currently. he only lives an hour and half from me. i can get you his information or find it in cody's signature. he has a thread with a number of examples of his work on h-t i believe. quality stuff

So i get a number of pm's concerning the k swap in a prelude. questions ranging from what block and head to go with to what all to expect with the swap. I am not complete with the swap yet so some other issues my come up but it is getting very close. hopefully the information below can help answer a few questions. i have been researching k motors online for a while now to figure out the best route and this is what ive come up with:

any k24 bottom end will work for a frankenstein k24/k20 build. The k24a2 from the TSX has the highest compression and is best suited for stock naturally aspirated power. the other blocks, i.e.: k24a4, k24a3 etc.. are lower compression and also lower horse power motors. i built my block with 12.5:1 comp wiseco pistons, forged blueprint rods, and ACL race bearings. my block decision was the k24a4 out of the usdm accord. this block is not really ideal but you can find it for very cheap. i paid $400 for the entire long block with wiring harness. the k20a2 oil pump is the most efficient oem oil pump option available for the k series motors. it is a good idea to replace the oil pump while the motor is out anyways so it is a good choice to buy a k20a2 oil pump (which you have to modify slightly to fit) and oil windage tray with bolts. there is an oil passage in the k24 block that needs to be plugged. you can do this with honda bond and a oversized bolt. if you search for this on google it will yield a thread with pictures to help guide you. that is what i used for reference. the k20 head you want to use is either the k20a2/k20z1 head from the usdm rsx type-s, the k20a head from the ctr or itr, or the k20z3. the ONLY reason to change the head on a k24 block is to utilize the higher displacement of the k24 for additional torque and use one of the better flowing heads that offer the 'true vtec'. the k series motors came with 2 different versions of vtec. ones that used one cam and one that uses 2 like the traditional vtec we are used to.
"Two versions of Honda's i-VTEC system can be found on K series engines; variable timing control (VTC) can be found on the intake cam of both versions. The VTEC system on engines like the K20A3 only operate on the intake cam; at low rpm only one intake valve is fully opened, the other opening just slightly to create a swirl effect in the combustion chamber for improved fuel atomization. At high rpm, both intake valves open fully to improve engine breathing. In engines such as the K20A2 found in the Acura RSX Type-S, the VTEC system operates on both the intake and exhaust valves, allowing both to benefit from multiple cam profiles."
the k24a2, k20a, k20a2, k20z1 and i believe the k20z3 offer the 'normal' vtec, higher lift cams, and better flowing head. so go that route other wise the head swap is pointless. if money is a big concern you can swap in the full k24 motor and do the head swap later but if thats the case then you should just wait to do the swap unless you buy a complete k24a2 long block and swap that. you can swap out intake manifolds to allow for a throttle cable instead of a drive by wire. the RBC intake manifold is one of the best flowing higher output oem manifolds available and you can find them online for about $150-300 shipped. depending on which head you use you will probably have to modify the mounting surface to fit the manifold and buy an adapter plate (k-tuned) makes one to run a normal k series throttle body. after the swap is in the things you will need are as follows:
-k pro
-custom engine wiring harness (i suggest buying one from wireworx here in florida. he will be making one for my car so he will already have the measurements and his work is amazing. look him up on honda-tech to see examples)
-custom header (so far the only one noted to fit the swap in a prelude is the universal swap DC Sports header. this doesn't yield very good power increases. i suggest going with an ALL IN Fabrication custom k swap header. they are $1200 but have yielded 13 hp gains over other k swap headers and the owner will already have the clearance measurements from me since he is building my header)
-tsx or accord shift box (this will depend on what transmission you go with. you can opt for the 5 speed from an accord or the 6 speed transmission from the TSX. i suggest the 6 speed obviously because that 6 speed is another huge perk of doing the k swap)
-tsx or accord shifter cables
-k pro adapter harness (this is universal and i suggest going through hybrid racing)
-custom fuel set up (you can also get this from hybrid racing. i will confirm in a few months to make sure that their universal kit works with the prelude because i have the hybrid racing tucked fuel rail, tucked fuel lines, fuel gauge, fuel pressure regulator, and inline fuel filter)
-custom power steering kit (hybrid racing also sells one of these. you don't have to run power steering but i am and i will confirm if the hybrid racing ps kit works with the prelude because i have one of those as well)
-custom intake (i am having ALL IN Fabrication make me a custom intake so you might want to go that route also or you can probably fab your own)
-custom fuel line (hybrid racing sells a k swap one for LHD or RHD cars which is convenient)
-hasport mounts (one of the oem engine mounts has to be removed and the has port unit welded into place)
-hasport axles
-a CRV side engine motor mount and one bolt is needed but you can buy that from hasport or their instructions give you the part numbers so you can buy it from honda or online.
-tune
-custom a/c lines if you are running a/c
-you will need an aftermarket traction bar. the only company that makes one worth getting currently is ESP (explicit speed performance. I have ordered a ESP unit but their turn around time is 7-9 weeks so i haven't received it yet. ALL IN Fab is currently in the designing one so that will be another good option.)

thats all i can think of right now. if i think of anything else i will let you know. feel free to message me with any other questions or ask on here and i will be happy to help if i can.

AWESOME!!!! If my H22a1 engine dies, i would definitively swap to K20A

SlimBB4

you will have to use a k24 bottom end and k24 tranny.
