View Full Version : RSX Type S Tranny

I was curious if the 6 speed tranny out of the rsx type s will mount up to the k24a engine out of a 2003 accord ex and will is it be possible to do a head swap or is it better to just rebuild my head with a performance valve train?

Okay- first thing's first.
Yes, the tranny should bolt right up. K-series is k-series, in terms of tranny.
Next up: getting head...
Head swapping will require K-Pro (see my other post for your ? about chips), and $$- don't bother unless you have deepish pockets.
Building your head will work as long as you leave the cams alone. Here's what you CAN do (no exceptions!) without K-Pro:
Head gasket
ARP head studs (HIGHLY reccommended in ANY engine build)
port and polish the heads (Waste of $- k-series heads flow enough air for 400+HP in stock form- polishing MIGHT get a pony or two, but for $700+, skip it!)
flat-faced valves (bump compression slightly, and reduce friction- might be worth it)
dual valve springs (not really a big deal with a stock redline, but it shouldn't hurt)
titanium retainers (less valvetrain mass= better throttle response, quicker revving, more power)
Grand total for ~$2k of work and parts:
Maybe 10 WHP
Worth it? Not likely.
For $3k:
$1k goes to a nice junkyard k20a2 (RSX-S- pre '05!!!) with tranny, harness, etc.
$900 for K-Pro
$500 for tuning
$600 for install/random crap
And you'll pick up more power, and have a motor worth tuning (shut up, Cham- I know! But still, $ for $ for a street car, it's true! :-p)

Again- fire back some questions, comments, or concerns! :) Mark W.

wow! i have a lot to think about.

i checked your profile and it says you have your own shop, that's sweet. do you work on other peoples cars and sell parts and stuff?

Well, now it's former shop owner, but I whore myself out to work on cars and whatnot. I'm actually now in tech school to help learn more and make connections. Just got in with Phoenix Racing in PA- they have 7 of the first 8 Turbo Solstices, and I got to play with them and meet GM Performance Division guys! EEEE! :) Very fun- easy ass cars to work on, suspension wise. The stock turbo setup is pretty narsty- well-designed, and not a lot of room for major improvement- can't wait to see the direct injection cracked! Sorry for another rant! :) Mark W.
