Weakest link in the K24 would be the rods, but there are so many group buys going on right now for quality aftermarket rods for around $500 that issue is eaisly over-come. A lot of people say the bearings as well, the new ACL race bearings are supposed to be out real soon and should help with that problem. If you're a baller you could go with the crower stroker kit which would over-come all issues with a stock bottom end From what I've read the stock K-series sleeves are thicker than B-series, I know someone over on K20a.org is in the process of a turbo build and plans to run 20+ psi on stock sleeves.. we'll see how it holds up.

I priced it out and to put together a turbo setup like the one above it would only cost a little more than going with an SSR header and a set of ITB's.. for the most part everything else would run the same, ie: cams, springs, retainers, fuel setup, cooling system.. only other difference would be that low compression pistons and turbo rods would cost less than the IPS spec. pistons/rods (IPS pistons would be required to run 50 degree VTC on K24 w/there cams, there rods are just highly recommended..) So all in all, it would probably even out...

So.... That was pretty nasty. I wish i had pockets that never ended, and a Wallet to go in it. -Ben

 

467hp on 13lbs? and spinning in 6th gear down the track. That puts my car to shame. and a slipping clutch

 

niceee

 

is the type-s tranny the same as the 06 si's? also is the head on each the same as well? and wouldnt a tsx bottom end make more power than the crv? just a few questions as I am getting an 06 si and want to do a k24 bottom end and turbo asap. thanks... oh ya, and if anyone knows how much power will the stock 06 si differential hold? and to whoever posted about the ips pistons and rods, where can I find them online? and the stroker kit... thx

 

WOW simply WOW, I love the k-series, Wonder if i can get hasport to make a kit to put one in my GTI??? LOL. Good find.

02-04 Type-S tranny (X2M5), 05-06 Type-S tranny (NSN4) and the '06 Civic Si tranny (PNN4) are pretty similar..

1-4 are the same on all three transmissions, 6th gear on both Type-S transmissiosn is 0.738 were the 06 Si's 6th gear is 0.659. The 05-06 Type-S and 06 Si share the same FD as the JDM Integra TypeR (RSX-R, Y2M3) which is 4.764 (the 02-04 X2M5 Type-S transmission uses a 4.389 FD, which would be better suited for a K24 motor). And of course the 06 Si comes with an LSD.. in essence the 06 Si has a JDM ITR transmission, the only difference being 6th gear.

The head on the K20A2 (Type-S) and K24A2 (TSX) flow very very similar, the Type-S has a slight advantage up top, but this is very eaisly overcome on the TSX head with a valve job and mild P&P, from what I've read they say the TSX head is actually a better starting point as there is more room for changes. As for the K20Z3 in the 06 SI I have not seen any flowcharts for it yet so I'm not sure how it compares.

In stock form, yes the K24A2 (TSX) bottom end would produce more HP than that of the K24A1 (CRV) due to the higher 10.5:1 compression that the K24A2 procudes.


I've yet to see a broken K-series diff and there a quite a few people making 500+ WHP on the various K-series boards. To be on the safe side perhaps you should purchase a Quaife, atleast then you know if it ever breaks its backed by a lifetime warranty.

I replied to your PM about IPS, hope that helps. Crower does make a stroker kit for the K20/K24 motors.

Some websites for you to checkout:
