I'm considering going turbo and have some questions about different setups. First and foremost, I understand that the Evo X turbo will fit in the 2010 GTS but I will need a custom downpipe and intercooler, in addition to that, what else would be needed to make it work and how much would I be looking at in terms of cost/aprox. hp gain? The other option would be the RRM turbo, which seems to be getting positive feedback from those of you that have already gone this route. For those of you that went with the RRM kit, what are your before and after hp #'s and does RRM offer a payment plan? I know this is a lot to ask but thanks in advance for the info!

 

and the other and preferred option is RA turbo If you use Evo X turbo on your 4B12 you should also use thicker head gasket to lower the compression. With RA turbo you will not open the engine, just boost less ~ 7psi and will easily do ~ 240 whp.

 

But i wonder how will our transmission (5spd) hold up at 240whp..

 

Well, there are many 5MT boosted lancers and it holds.

 

I know its just a question for how long tho.. ill be boosting my car over the winter and i already went thru one transmission at 50000km.
