Tsx Engine Swap - Page 2

^^ I actually looked into doing that and my friend's shop had a JDM K20 Euro R engine sitting there. It was so tempting....but, like we learned in Econ, the Opportunity Cost was just not right...

haha yeah... and also that time i posted up a genuine jdm k20 for 4500 bucks. and nobody picked it up.... shrugs.

The head on the K20A is pretty superior to our TSX head. The legendary K20/k24 hybrid might be something u want to look into. K20A head with a K24 block would essentially be the best of both worlds. You'll have higher compression and red line. K-pro would be necessary, but if ur seriously considering a swap from a TL-S engine, K-pro would be minor in comparison.

I've seen naturally Aspirated RSX's with the k20/k24 hybrid engine put down an easy 250 whp.

TSX_WS · 06-08-2009, 11:15 PM

^ How exactly is it superior? And why would redline be higher with same long strokes and high piston speed? K20A head sure is superior to CR-V's and Accord's engines, but TSX?

Well the main reason for the K20a2 head on our block is for clearance but I also heard it flows better.

A J35 swap in a CL9, idk man. Thats a bit much in my opinion. Plus look at it this way, those motors will not be cheap. If you want a nice ride, IMO, get ITBS, Kpro, Stage 2 cam, new valves, and if you got the money, stroker kit. So you'll end up with a 2.6 liter four banger with a great amount of power. If you drive stick, get a type-r final drive, like from the DC5.

so would the k20/k24 + kpro be better and worth it?

^ sound like a pretty nice setup thanx

It would definitely be worth it if u had an accord with 160HP K24, but with a TSX.... begin where u are with K-pro and keep working.

i was thinking of a an accord engine a newer one since they come v6 but idk if those engine would fit either?

There is no difference in clearance if you slap on the k20a2 head. And it only flows better up top. The k24a2 head flows better down low. Hence the torque. On another note the k24a1 has the same flow rate as the k20a2. But IMHO. The k24 heads are far superior to the k20 heads. Due to the fact that a ported k24 head will easily outflow a ported k20 head.

And to the debate that the type r motor is better. The way I see it. If you don't have the type r motor in the car. Why bother swapping one in. The cost for the motor alone would get you enough parts to have a better motor than the type r motor itself.

Yessir, very well said Kuma.

to the OP, you have a stock motor pushing 200 hp, we can now tune with K-pro which opens up "a whole new world" of huge power gaining mods. there is no reason to swap out for a different motor that is going to throw the balance of the car off. just stick to saving your money to boost or build the internals up... you'll be happy you didnt swap the motor when all is said and done.

you're better off buying another car

Otherwise they have same 310CC injectors (as opposed to Accord's and base RSX's 270 CC), VTEC on both exhaust and intake cams, 06+ TSX has more aggressive cams all around, stronger crankshaft, more displacement, both can be tuned with K-pro.

Not being an ass but... its 50 degrees...

TSX_WS · 06-09-2009, 02:56 PM

^ 50 degrees is physical maximum, electronically its limited to 45, thats why its commonly referred to as 45 degree VTC mechanism.
