If you can leave the boost alone at 4-6 psi, ... you will be as close to plug and play as possible. If you have already added a freer exhaust, .... all the better. The Hahn kit will be a MARKED-improvement, .... just as it comes! It can also be upgraded very easily later, without throwing the existing stuff away. You simply add the intercooler, a larger set of injectors and the Crane boost retard ignition at that time, up the boost to 8 psi. Those 4 things will add about 60 horse power!! (IC, injectors, Crane Ignition and 8 psi boost). ... an insxpensive BOV is a good idea too!
BUT BE WARNED !! go *** "NO" *** further until you do the bottom end!! .... if you have detonation and keep your foot in it, .... it could get UGLY, .... even at 8 psi boost. So the ability to tune your turbo system is very important!
I will be glad to assist you in the install and tuning of your system. I can even save you some bucks on the kit and upgrades when you are ready for them.
