I currently have an Fp Red, MX 1 cams and all supporting mods pushing 440whp at 28 psi. I'll soon have a built either 2.1 (or 2.2). I really want to reach 550whp on 93 pump. The highest I've seen on a black is slightly over 500, and up to 590 on ms 109. I have a lot to learn about turbo component sizes and was wondering if anyone's made 550 on a pump. If so, on what turbo/setup? I was looking at some of the AMS setups but as i said, when it comes to picking the turbo.... I have no idea. (yes im researching in more places than evo forums)

 

There is a local here in Hawaii on stock block AND CLUTCH making like 560whp... but I believe that was on race fuel (AMS 750R and Jun 272 cams)... but honestly his TQ was very limited for obvious reasons. Getting 550whp on pump maybe difficult

 

Also interested in making 550whp. Needs to be daily driver, dependable, and quick, as in spool, and pools strong up to 8500 RPM. Also considering 2.2 big bore but will consider 2.3 stroker, or even 2.0. Just want the quickest street car that can hold boost to 8500 RPM and fun to drive. Will consider any turbo. Here is the catch for me though. Under 6k is my budget for engine build and turbo. If I'm to spend more I would put it down on a GTR and call it a day. Suggestions?

 

Im not sure you can buy the kit and do a block for 6k. Im using a 15k budget on my upcoming build which I have been told is about right. I mean the 750r alone will set you back 6k with shipping... plus a clutch and fueling... then you still have to deal with the block

 

When i called AMS with this question they said that i could make 500+whp on 93 with a 900x turbo kit with a stock block but they said it was pushing the limits of the stock bottom end
Im sure you can make 550+whp with a built motor and a big turbo kit on 93 but then again you gotta worry about knock
