So i think i am doing a new stock 2.2 bottom end in my ap1. I know it fits and all the wires are the same but what do i need to do to rev it to 9k still.... i would think jsut my cams and springs and a tune..... but just seeing if anyone knows what needs to be done or has done it before.

If all you want to do is rev to 9k, why don't you just get another 2.0 bottom end. The piston stroke of that motor was designed to rev to 9k, not the 2.2. Some people are using F20 ecm's with the 2.2 and revving them to 9k without problems. This doesn't mean that there wont be problems down the road.

I believe the 2.2L blocks are different at the bottom of the sleeve? I presume for rod clearance. You might want to check that.

There are several issues with 9k on a 2.2L, primarily piston speed. A 2.0L head has no problems with 9k; it's your connecting bolts/rods/pistons you should be worried about.

well it might be a whole 2.2 motor i was goignto swap the cams over. so is the head on the 2.2 the same.... i now the cams are different but other then that? not sure of. also i wanted to make more power the reving to 9k does not matter... but i know the power on the 2.2 is still increacing at the red line.

Build the head... You should then have no problems revving to 9k safely...

KAY'S

umm there is nothing to build..... doign valves will do nothing neither will a port and polish, and i know my 2.0 springs and cams will rev there.... and the i was mor worried about clearence and stability of the bottom end. so come on man....... if you don;t know you don't have to post.. but no blanket statements like that please.

The cylinder head has nothing to do with the increased piston speed of the 2.2L

If you wish to run a 2.2 to 9k, be prepard to eventually have a rod/piston failure. You'd think the company that designed the engine may have a reason why they lowered the redline from 9K.

It is you who seems to be on the short end of the information stick. Perhaps you should do a search on Alaniz Technologies... just a thought.


This is what I have heard. I don't have emperical data to support it, just what I've heard. I know Nik(Silver04S2K or something like that) blew his motor up only having the rev limiter set at 8500 on a boosted AP2(9-10 psi, I think).

i have built more cars then i can count at this point, but never a s2000 which is why i was asking.... so i am short on the info.... haha which is why i posted the question, but thanks for stating what we already knew. and i Alaniz Technologies... but what does that have to do with my question on the reving...... it wasn;t me that was talking about building a head. Thanks for umm i guess nothing.

SlowS2k hit it on the head.

the problem with getting a 2.2 to rev to 9k is the BOTTOM end. not the head.
