Re: K24A4 turbo vs. K20A3 turbo (bunnyrabbit)
the k24a4 is an overall better motor.. more discplacement, hp, tq.
i believe i has a stronger bottom then the k20a2 but a weaker head. not totally sure.

you have a COUPLE of k20a2's being built and you are still spending time on a k20a3?

I don't know how the K24A4 rods and pistons compare to the A2 off hand but if your planning on going that route, choose your turbo wisely.
Although the rod bearings are wider on the TSX motor, the motor is not meant to be revved nor will it last. Maybe go with something ball bearing that spools quickly to take advantage of the larger displacement.
As far as the A3 goes, I'm not a fan of boosting them. Although the CR is low, the rods are extremely weak. The crank is not well balanced and there are no oil squirters.
Between the 2 I would go with the A4, slap a set of off shelf forged pistons and rods, keep the stock sleeves and call it a day. Although it can't be revved to high the larger displacement is a plus.
A2 owns both though. But if you destroke that K24 its all over.

Re: (bunnyrabbit)
Really it depends on your power goals. People have had success with the A3 below 300 hp and with a GOOD tune.
When people go with a hybrid K24/A2 or A3 they usually swap out pistons and rods too. Its just convenient when the motor is out. Therefore I can't give you too much insight into how durable the A4 bottom end really is. Also, I have never torn one down. But I have seen first hand the diff. between an A3 and A2.
Basically if you are staying below or even close to 300 I would keep the A3. If it blows, then go A4.

Re: (bunnyrabbit)
If you just want something to hold you over till you get your hybrid up and running, then just turbo your A3. Keep the boost low and enjoy. Why go through the trouble of swapping blocks twice?
Only problem with doing this, is your goals are going to change. Right now you are looking for under 300hp but when that hybrid is done chances are you want 400 plus. Choose a turbo kit that allows you to upgrade very easily. Something like Full Race, SCI, or peakboost which is coming out with a kit for the K series.
Good luck

Re: (bunnyrabbit)
If you have the motor like free, put the K24 in simply for more torque because more displacement. Its not cost effective, tho it may be "cheap". Id say turbo your EP3 motor, cause buying and swapping in the crummy K24 aint worth it, cept the TSX motor (is that the a4?)

TSX has the K24A2. Not the A4.

Re: (Hype Vtec)
i think it was honda tuning that did a full write-up on a tsx block/rsx-s head build up. They said it is how the k20 should come from the factory. ill try to find it if you want more info.
