So I have recently gotten a complete engine that I want to rebuild from the ground up. Cylinder 3 and 4 will need sleeves and the valves for cylinder 4 needs to be replaced. So basically I want to make this engine my race engine. My desires on it is to keep a similar to stock power band...love the high revs, and get a reliable 450-500 whp. I am looking at doing an E85 system through SOS. I already have their 8.5 lb flywheel and clutch kit an love it. I am looking to get the SOS supercharger kit at some point. So first off can you point me to similar builds? Also what are good sleeves to use?

A stock rebuild can handle 450-550whp with e85 no issues. With that said, it maybe cheaper to just find a low mileage shortblock or long block IMO

I would use darton dry sleeves, cp Pistons, bc or inlinepro rods or just send it to inlinepro. For the head ferrea comp plus valves and dual springs.

I have built an s2000 engine before I don't don't suggest anyone do it for less that 700whp. My stock engine has been dead reliable at 620whp with 125,000 miles and been boosted since 80,000 miles.

500whp is nothing for the stock engine.

Okay so I understand the stock block can handle that much power but what I am trying to say is that 450-500 whp is a starting. I want this engine to be done to where I don't have to take it back out again to build it up when I decide 500 is not enough. I am planning on doing the SOS 1200 kit. So with E85 I will be able to do well over 500. When I am ready to crank it up I want to be able to. I also am thinking of doing an ecu that can hold 2 tunes for this reason if I can find an ecu that will allow that.

I get that but I just but this engine for the experience in building an engine with my son and for a racing block. Obviously not gonna just turn around and by another

Is there a reason that you don't suggest it?

Sorry, I didn't know the additional information you withheld. Understand that it is CHEAPER to "turn around and by another" which was my suggestion based in the initial information provided the in first post. Have you built an S2000 motor before? It's easier to rebuilt it to stock specs, however, if you plan on running tighter tolerances I would suggested allowing professional shop to blueprint and build it. These motors are very picky, I would hate for you to waste more money than planned. FYI Im on a stock F22c with SOS SC @14lbs roughly in the 450whp range on only 93octane, check out my thread. The limit for power from the Novi 1200 will short you first before the limit of the stock engine.

Sorry for writing in a hurry earlier and not giving all the info. I understand you are not a mind reader. Wasn't going for being rude. I have not built an S2000 motor before although I have built many stock engines working at Ford as a mechanic and built about 4 late model engines. Also when I say this know that I will not be doing the machining.

Also sorry but I feel like I should let you know that the engine currently in my car is fine. This is a spare engine just to build on with my son as he grows up.

For what reason do you want to have to built the engine? What benefits do you think you will get? For you low power goals all you achieve if a lighter wallet and longer/pospone down time of the car. For under 700whp the the stock engine will make more power due to the high compression and will be more reliable.

The stock engine will and can handle well over 600whp quite easy. More than any supercharger can make. The stock engine will most likely be much much more reliable. You wont worry about if the new engine will be built right or if/how long it will last.

If you do go with a built engine at least go with a 2.4 stroker crank/rods. At least you will get high torque/ better low end and faster spool for turbo.
