I am in the process of gathering all the parts to build my motor up to gain the most power possible. I would also like for the motor to be able to rev as high as I want to take it. I am talking around 10k to 15k rpms if any way possible. I think that I have heard of something like S2000 crank that you can take and put in a K20A2 block but as far as what needs to be done to either the crank or the block I am not sure. Also I am not sure as to what connecting rods to go with? I am wanting to get somewhere around 12.5:1 or 13:1 compression with somewhere around a 89mm or 90mm bore if possible. I would also like to have to be somewhere around a 2.2L or 2.3L if any way possible. If someone could help me out on getting some stuff straight or even if this build would be possible let me know. I am wanting to know if there is any way that this is possible or not. Let me know what I would need to change to make this possible crazy build even possible.

 

Well first of all, your RPM goals throws a red flag right when you read it. I cant stop focusing on that 15K RPM. hehe. What is the reason to taking it up that high? Is this a full race engine? Strictly for track use? Drag or road racing?

You also have to consider that you only take it up to a certain RPM because the cam/compression/etc will still make power up that high. There are also oiling issues you have to consider when taking it up that high RPM. Are you going to run an aftermarket/external oil pump or using stock oil pump?

Theres so many factors that can determine the right answer for your question. The displacement you mentioned isnt out of reach. I think you just have to let us know what type of use this engine will be for to get a proper answer.

 

If you want to rev that high get a F1 engine or get hondata/ crome whatever and disable the rev limiter, it's a 1 way ticket though. hahaha.

You sure are asking much for your 2nd post on ht. Do a search and see what other people are running. That can get you started

 

well for one lol 15k is a no go. the only way ur gonna get close to 15k is be de-stroking the motor and de-boring the motor so u can run smaller pistons and have a much smaller stroke. 15k for a motor that barely has any rotating mass and has a short stroke is very easy to do but ur not going to make any power up there not to mention the port job on the head is going to be insane.

ur also gonna need a dry sump oils system which is expensive as hell.

y do u wanna rev that high neway?

Cuz its cool to rev high, right?

Give me 3 reasons as to why youd want an engine to rev that high.....
