I'm a newbie here so really don't want to offend anyone.

I've got experience, but no where as much as the OP has, on playing with cars including turbo charged ones.

I have but one question.

Why would you want to go through all this just to add 30 to 50HP more i.e. 10 to 15% ?

The rods nd pistons aren't the wesk point. It is you cylinders themselves. LNengineering and 10k+ later. Oh and another 5-9k in the bank for when you blow it up.

As someone said a s/c is more linear. That is probably why a rising rate fpr will work with no tune. You are running a much more agressive boost curve with a turbo charger. Ya it's only 3 psi but you're talking about a 5-9k dollar used engine. They don't cost 500 bucks like all those jap engines you'r used to. Do some more drawing on your board first.

30-50 hp to start, to mock up the kit and make it work work on tuning it. The turbo wil support up to 500.

Maybe I should be more clear about my current engine - Though I haven't owned the vehicle for long...At around 30,000 miles the engine was replaced with the upgraded design. The transmission was remanufactured and the bottom end was rebuilt just recently, with the following - I am not sure if the replacement engines had the sleeves upgraded? Maybe someone can answer that question for me.

So here is the new part of the new list 10,000 miles ago - The Cylinder walls still had the crosshatching from when the engine was replaced- It also has the the large factory IMS because the retrofit was too small(was going to replace it just in case while we were in there) This was just the things I have record of - I ordered the gasket set and a few other things from somewhere else

Huh? How much would it cost to get that much from a na engine?
lets go conservative here -

headers - $800
Exhaust - $800
Intake - $300
Ecu tune - $1000

roughly $3000 with tax - and you are not likely to get 30 hp to the wheels. Some of these responses are very strange... I expected much more support.

What do you really think it costs to build a turbo kit? - I will be shocked if it costs that much more than $4000 even buying the best of everything, to build a kit for this car, give or take $1500 if I decide to have the ECU tuned

I have $13000 dollars in the car - even if I put $20000 into an engine and turbo kit ? are there a lot of $33000 dollar 996tt's out there of any year? This was the whole point of me purchasing this car. I wanted a 996tt but it didn't make sense for me to pay $40,000 Plus When I have 2 other supercharged cars - This is what I do for fun

LN nickies (cylinder walls) are billet. Oem ones are prone to D cracks and sinking. You should have went with a c4s to turbo if that was your plan. You are right about the fab parts only costing, upto, 4k. I think the best way is to build the engine with cams and uping the liters with a LN nickies setup, do weight reduction mods, then at the end use a supercharger kit. Granted that is a lot of money but in the end it will still be easy to remove the engine without all the turbo kit pieces and not to mention all that extra weight. You may gain 30-50 hp but are you adding the extra weight to power ratio.

Years ago I supercharged my boxster, everyone said it wouldn't work. I beat it for 4k miles before I sold it. I've attempted to contact the guy that bought it and see how it's running, but I can't get a hold of him. Maybe he blew up with the car, lol.

Good luck and I mean this in the nicest way.

Let us know how it goes.

I'm planning on doing this to my project car, a '99 996 C2. Bought it as a non runner and been fixing the engine for the last 2 months. It's almost ready to go back in but before it does, I would like to prepare it for when the supercharger gets dropped in. I have a spare SC from an M5 that I'm planning on grafting on. My other Porsche is a supercharged '85 928. I did all the fabrication for that too, and learned that next time, I'll do it with the engine out. I've been looking for information in where to get the oil feed line on the engine but I can't find any real information. If anyone has first hand information, please post it.

If i was you id look into swapping a LSX motor into the car insted of turboing a motor that isnt exactly the strongest one out there
