hi, im going to be doing an engine swap in my TII and i came upon this 2 engines
13BTT and 13BRE sequential twin turbo, i just want to know whats the difference between those 2 engines and which is better. and yes im also considering the 20B, if someone can tell me what engine swap is better i would apreciate it.

thanks

 

A 13bTT is not exactly a Mazda engine code I dunno where you got it from. The RE is a TT setup and the REW is as well. The RE swap will be easier and cheaper then the REW swap and most users will say the RE is worth wile compared to the REW. Since you stated 20B I assume you have allot of money on hand so pick whatever one you want.

I really don’t see any reason of why your would swap a 13bT for anything other then a 20B for reasons of pointlessness but one to his own.
