I'd kill myself in an RX-8 ... have fun with it man cuz I'm sure you will!!!

Matty's wrong. They're not even the same engines. The MSP have a 4.7 liter inline 3 cylinder. Duh.

Id go with the 2.0 from the MSP. But change some things. Personally Id change the BOV and then go with a front mount intercooler. But id also change the pistons and add a boost controller.
and then go for the Engine management system and fuel rail and a larger fuel pump.


The advantage you have is that you can work on the MSP engine and still drive teh MP5.

I have a MSP and cant do the mods because its a daily driver and i dont have the money to blow all at once, but id like to have all the mods at once.



But dude, its your call. you can add a larger turbo to the MP5 engine. But the MSP has most of what you want anyway
