Oh wow. Yeah thats why i decided to get a 1.8 over a 2.8. I had a few 2.8's that i was looking at but then i read the newbie thread and it set me on the 1.8t because i wanted to do some work to it. But i think the 2.8s make great show cars.

 

No offense but I had to actually process what you said. It makes very little sense. All this guy would be doing is essentially making an S4. With the B5 S4 you can make enough power to make weight not really a factor. Look it up on youtube. There are a few 800 hp B5 S4's out there that will stomp a 1.8T in handling as well. The extra 100 lbs. hardly matters anymore.

 

Actually brother, if done right the turbo's would be more reliable over the long run and since you have a small motor turbo's take less power to spin. With a torquey V8 it doesn't really matter since you already make plenty of power naturally aspirated. If you want big power you have to watch what you bolt on to small engines or your gains won't be that great for what you spent on parts. To me 2-5 grand for 100 hp (PES) just doesn't sound that great. I've done the research and decided that if I go F/I I will be procharging or turbocharging.

 

Same conclusion I drew. If all the bugs could be worked out and all the other necessary things that need to be done in order to run PES all for under 2 grand, it might be worth it in that case, but after you get the kit itself as well as any modifications to the exhaust and such that you have to do to see the full gain of the system, you're in it an extra grand or two, and for that, you may as well just take that 4 grand and put it towards an S4 or at least a 1.8t IMO.

 

Personally, if I supercharged anything, it'd have to be a twin screw setup like Kenne Bell has (not for these cars though).

 

The closest to supercharging I would go for a 2.8 would be a procharger. Prochargers offer the best of both worlds when it comes to F/I. The reliability and efficiency of a turbo and the instant boost of a supercharger.

 

Is the PES supercharger unreliable? I dont really know anything about it. I do know that a bolt on kit will be much, much easier to get going than a custum twin turbo setup that reuires custom fabrication, tuning, etc. Once you do get the turbo setup working, and IF it is done properly you will still run into problems that require specific knowledge of your system. I dont know what the stock internals of the 2.8L can handle, but that may also be a factor once you start pushing real power.

Im not saying that the supercharger is worth the money. But besides the cost, it is an easy way to upgrade power. But like I said before, I wouldnt start a twin turbo project just for the fact that there are two k03s in the shop.

 

The stock 2.8 internals can handle around 12 psi. Too much more than that and the pistons may want to vacate the block and decide they want to take chunks of the block with them. The fact that you found 2 free k03's would make me want to start the project. Brand new, two k03's could run you about 3-4 grand. Even rebuilt ones are expensive. That takes care of about half the price of the project if you do the vast majority of the work yourself. I priced just parts and for me with the tip tranny it would run me $7-$10 grand for a twin turbo set-up.

 

Personally, I don't think K03s are even worth the effort.

 

Your mom's not worth the effort. :P
