Hahn kit on an r/t

[TheTransporter64]

i have a 01 r/t and i'm thinking about getting the hahn turbo kit with a 20g turbo and building up my internals, i'm also concidring using the hahn portfuler and wanted to know what everyone had heard about it. also do i need to do something about timing advance with the r/t and what would i do about that.

Your RT engine has larger exhaust ports then the standard head. With that said the Hahn manifold will bolt up. You will have to have the Manifold gasket matched to open up the exhaust ports on the manifold to take advantage of the larger ports of the RT head(did an RT headswap with a hahn kit myself)

dont know much about the port fueler other than its overpriced and you can do more with megasquirt for about 1/4th the price.

Megasquirt will take care of the timing advance also, If you decide to keep the RT computer then you will need to run some kind of system that pulls timing when you get into boost. such as a crane hi6di2 igniton box with boost dependant timing retard. you will seriously need to tune timing on a real dyno, the butt dyno will only lead to destruction when tuning timing with that much advance.

personally you have a lot of work ahead of you before your car will handle a 20g. if i remember correctly the 20g comes with a 14psi wga, so dont bolt it up until you beef up the motor.

good luck
