Anyone have experience with what the RSX-S engine will take in terms of power? I've heard of a few guys running 300+whp on a completely stock motor with a turbo and I'm curious if anyone can confirm this?

I'm curious because I have a friend with an rsx-s, and he wants to see 350+whp. I'm encouraging him to go with some 9:1 pistons, rods, cams, ferrea valve train, AEM EMS, Quaife LSD, CM Stg.3 clutch, and base it on the the Rev-hard turbo kit (T3/TO4E) currently available for the RSX.

Any help and/or comments would be much appreciated.

but in http://www.clubrsx.com theres alot of boosted rsx s on stock internals. check out the boost section

 

I wouldn't recommend pushing it any harder than the big names already have (ie: Greddy, Spoon, etc)

 

Spoon turbo'd and Rsx?

not to my knowledge...

 

Ya im going to say no, they havent.

 

Spoon doesn't tune turbos or add turbos to their demo and race cars.

In A&J's correspondances with Spoon, Buddy Club, Alex, and other Japanese race teams, we have learned that the K20A motors are weaker than the previous B18C. The K20A's are very similar to the F20C in that the block is fairly thin and is not as durable.

The K20A and F20C will rev like crazy to high rpm. But when they let go... they let go catastrophically

Mind you these observations are for endurance racing, races that last 4 hours and one that is 24 hours; and the motors are relatively stock. Street driven and drag racing are totally different. Nevertheless, Spoon and Buddy Club have both told us about blown K20A in their enduro race cars. If you take a look at the final results for any SuperTaikyu endurance race, you will find many of the DC5R fail to finish, although they are fast.

Another weakness of the K20A that wasn't there in the B18C is the transmission. The K20A's transmission is similar to the F20C's in that for racing purposes, it will require the use of a transmission oil cooler, which wasn't the case for the B18C. Transmission failure is another frequent cause of early retirement for endurance racing S2000's and new Integra Type R's.

 

No limit soldier, I thought I told ya!

Lowering the compression on the K20a2 is a good Idea because 11:1 isn't good with high boost. 9.5:1 would be ok maybe 10:1. Custom turbo kits may be the best route to take.

 

I would not recomend 350 on the stock bottom end...an im pretty sure that no one else would either....that is...IF you can squeeze 350 out of the stock bottom end.

 

Yea....350 whp on a stock bottom end is nuts....i have ran 14psi with no exhaust (maybe 340whp) but never 350whp, right now for daily usage i am at 9psi and 12psi

 

Well, the only stock part that would be left in the bottom end would be the crank, and even it would be balanced. The rods are now available through eagle, arias has 9:1 pistons for it, cat cams new cams for the K20 make more power under the curve than the Todas, and the rev-hard turbo kit with the T3/TO4E should be up to the task. I don't think 350whp is that much more outrageous than 340whp on what I'm assuming is a fairly stock engine. Am I that far off my rocker?
