K24a 5spd Swap..

[Jarrett]

Go with what you have for now. You can always get a different transmission later. Besides, you'll want to go easy on it through the break-in process, anyway.

What do you have planned for wiring? Are you going to run an OEM K-series harness with the necessary adaptive wiring for this chassis, or are you going with a fully custom wiring harness? If budget allows, I suggest the latter. It will allow you the most flexibility in terms of what you want the engine wired for.

I'm also curious as to the chassis that this car will go in.

I have the OEM RSX-S engine harness and I will be sending my original harness off to Hasport for adapting to the K20 harness.

This all will be going into my 90 Accord EX.

Another quick update.. Polishing my IM, almost done. The following parts have come in since last update:
- JDM Nippon 12.4:1 CR 87.5 Pistons
-OEM K24 crankshaft (needs to be micropolished)
-K1 Lightweight I Beams Rods
-ACL Race Rod & Main Bearings
-OEM shift cables, alternator, AC compressor and PS pump

Very nice. Keep it up!

['93CB7Ex]

moving right along. making more progress than mine hah

[mjsstanley]

Thanks guys. I'd be even further if I could find a way around paying $450 for some axles. The axles and KPro gonna delay the process a little bit. Probably go ahead and have the block built in the meantime. Gotta figure out the exhaust too.

LSDs are transformative. I had a Quaife in sparkle's swapped CB, and the LSD was easily the best part of that car. With all the stuff you're doing, if you're gonna open the transmission at all it's a no brainer.

[deevergote]

LSD types matter, though. Viscous types are barely better than an open diff. Helical types, like quaife, are probably best for a street car.
My Miata has a viscous lsd. It's ok, but I'll probably swap it out for something better if I decide to keep the car for a long time.

Really? Isn't it like 150HP?

[mjsstanley]

Ok so I'm guessing I really need to look into the LSD. I have gotten confirmation that I can add it to the tranny that I have already. However, it may be cheaper to sell what I have and get a 6 spd tranny with LSD already.

[Granite CB7]

^yeah, that's what I would do too and find a 6 spd w/ LSD. Absolutely sick build, I really dig what you're doing here and great work on the IM

['93CB7Ex]

ill leak the axles. you use prelude type-sh axles. at least thats what i got sent to be claiming to be "k swap axles".

[mjsstanley]

GRANITE CB7 I appreciate it. Will be sure to keep you all updated. I'm still not completely set on having LSD but if I do end up deciding to go with it, I'll sell the RSX tranny and pick up an SI with LSD.

93CB7EX That is awesome if those really work!! Let me know how that goes.. Where'd you get em?

dude on facebook. they are insane shafts.

PM me his info if you don't mind.

[mjsstanley]

For forever I've been trying to locate a straight thru piping setup for the CB chassis and I've finally found it. Got a straight pipe exhaust from TruBendz for $150. They're available in 2.25", 2.5" and 3". Piping allows you to use whatever muffler and resonator you like. Header on the way also.

[mjsstanley]

My SOHC is definitely on its last leg so getting a move on on the K24/K20! About to send block off to the machine shop for cleaning and boring. After that's done, engine will be assembled

[mjsstanley]

Another update guys.. Engine being assembled currently. I did decide to go ahead and get an LSD and use it with the 6 speed transmission. Really hoping to have swap done by the end of July!

Cleaned and painted '06 SI transmission casing


Transmission internals from the RSX-S trans


Yonaka RSX-S Axles (swap the inners and they work fine.. or you could also use TSX axles with CB outers)


OEM LSD from '12 Civic SI (12k miles)


CX Racing triple core half sized radiator w/ 12" fan


JDM Civic Type R ECU w/ Kpro


Vibrant 2.5" Muffler

LOL. More like 110. You don't need lots of power to justify having an LSD from the factory. True driver's cars have LSD's. Open differentials are completely logical on most cars, especially ones like the cb7 - which is an economy car.

Once you see power increases, LSD makes worlds of difference, especially in FWD configurations, where torque steer results in understeer results in crashed car.

Volkswagen has some amazing fwd transmission technology going on with their LSD's and whatnot.

Torque steer and understeer and two different things.

Torque steer is caused by unequal forces applied to the wheels of the opposite side (think torque vectoring).

Understeer is when you reach the limit of traction and the car no longer follows the steering angle, but follows the direction or the momentum of the vehicle right before it lost traction.
