A little over two months. to me its better to just turbo the 6 port. you wont hurt anything at 5psi and with the right turbo set up and tuning be well above 200 hp to the wheels. my set up costed me about.. 1500-1700. what kinda t2 swap can you do with that and have over 200hp to the wheels? if you where you can get the parts for that cheap lemme know.
Who wants to run just 5psi/200rwhp...

My point exactly; the car has been running for only 2 months. A friend of mine ran his stock t2 at 14psi/17psi for 2 months! Sure he thought it was fine and still does. He blew the motor.

I'm that one that has posted pics of a split diff from boosting a 6 port. I definitely saw more than 5 psi when it did that! I modified an S4 TII intake to have 6 ports at the flange by welding and then remachining it. I used the starion front mount intercooler, and all of the exhaust manifolds and turbo from a j-spec S5 a friend bought. I have an RB presilencer and 65mm HKS mufflers - no cat.
With this setup I had an AWFUL boost curve. At 5000rpms I could see as much as 13psi (I programmed it to cut fuel at 12.5) with the wastegate (stock, unported) open and by 6000rpms the boost was dropping down to about 7psi.
I ended up blowing a water seal, not to mention wearing out my rotor housings from them moving against the side housings.
So, I pulled all the turbo stuff off, built a large streetport engine, and installed it with all the original S5 NA fuel injection to see what normally aspirated fun I could have. I swore I wouldn't play with boost again....
I have almost enough mileage on the car for my first oil change and I'm already thinking about turbo'ing again! It pulls good NA, but boost is so much better!!! I would like to find a better matched turbo so I can maintain a constant 7 or 8 psi over the usefull operating range. As long as I keep the boost down it's gotta be ok... Those 12.5 - 13 psi spikes were hard on everything!!!

Fatazzgxl, please give me (email at kornmanxxx) or post in here ALL of the parts you bought, brand name, and approx. price. I would really like to compare. Because remember, my engine's toast, which means I have to buy a new engine anyways, and the T2 engine is only 200 more than the n/a. Just my opinion, and I'm not knocking yours, I just need all info to correctly evaluate the situation. Thank you for all of your posts, keep 'em coming!
