hi, i got myself a 2006 ralliart not too long ago....some people say the engine is trash others say its good....i need to know would the 4g69 be worth building for a small but fun setup? i dont need more than 300whp i just want a fun little go kart ive tried to search the net havent got any good answers thanks

 

The ralliart is an amazing car to upgrade and the torque it has is second to none I say hell yeah do it There used to be a company here By the name of road race motorsports They used to sell a Turbo kit for the car but I think they are out of business now

 

If you are planning on running more than 8 - 10psi, you'll need forged internals. I think I've read somewhere that someone was able to push 300hp n/a. I don't remember what engine work they did though.
