To get 150-170 will take a bit of work. Stock numbers were around 70hp. SO you are looking at about 100% increase. It can be done. Stock exhaust will need to go. Bigger DP and at least 2-2.5" all the way to the end. Either straight pipe or a good turbo muffler. Intake will need to be modified for better/ balanced flow. FMIC or water injection. Good cold air intake. Pump adjustments or rebuild Covered in the FAQ section. There are some very good pump builders on the forum, tintin-giles etc. Full up guage set so you dont melt anything. EGT and boost minimum. With that many miles you will want to think about the bottom end being redone if you are going to be pushing big numbers like that. IM shaft bearings. Make sure everything is up to speed on the head, valve guides, seats etc. Porting works well. Clean up the exhaust side of the head. Open up the intake side. Gasket match. Upgrade to 1.9 HG. Think about head studs. EGR delete, you will need to increase boost levels up into the 20+psi range. How is the turbo? Still tight? Once you get your power you need to put to the road. Lightened 210mm flywheel and clutch setup, Uprated 16V pressure plate. What tranny does your car have? Sounds like you are pretty handy if you already did the work you mentioned. Most of this is just hands on. No chips or electronic stuff. Good old fashioned hot rodding. Just more fuel, more boost, more flow. It really depends on how deep you want to go into the engine and your wallet. You will find tons of good info on this forum. I would suggest about a month of solid reading, question asking, research and planning. It is very easy to get the bug and end up WAY WAY over budget.Good luck,Jim
Your Injection Pump will be the heart of all your power. A stock rebuild will be just that. You can always adjust it from there as described in the FAQ section. That will get you some pretty good fueling advances to allow for more boost / higher rpm. I dont think it will get you to 150hp but it will move you a good bit past stock. The next jump is to have a performance rebuild of your pump done. That is where you really need to do your research and check out some of the better pump builders. It's like a skill level jump from college football up to the NFL. It's all custom work. It's also about 800-1000 bucks. Not cheap.I think to do everything right for a reliable 150 daily driving hp will run you 1500 to 3000. Soup to nuts. Engine, turbo, tranny, exhaust etc...You should have no problem hanging with the vr6 class unless they are all decked out high hp units.

The damn thing is too quiet though even though it's a straight through. It will probably get louder though after those little perforations start filling up with soot. You wouldn't believe all the *** in one of these things inside the case if you cut one open after it's been on there a while.Yeah, ive been reading non stop for the day pretty much and of all shops that tune pumps everyone seems to swear by giles... so i did just that and messaged him. i will end up going with a giles built super pump... that being the biggest expense in this build...this evening i added an order to my buddies large order of SS from Ace metals down in Cali... even with the dollar being weak it still worked out to be cheaper. my friend swears by him said we should have it all here by Friday this week. going to be fabbing up a turbo back system.thanks for the input on the magnaflow muffler... im going to run it as a straight 2.5'' at first no muffler....if it gets loud or drone i can always hack it up and throw in a muffler so thats no big deal.as of right now i put a cap on the amount of money im willing to spend on engine parts/performance at around the 3k mark.a grand is already used for the pump....i cant wait to see the look on the vr guys....thanks for all the info so far! this site has alot of knowledge
