Again thanks

Hell yeah that's what I'm talking about! Give us an update when you get it up and running. And if it lags shoot nitrous 50 shot that's all it needs. HAHAHA...

Back in the early '90's, NITROUS wasn't readily available in Japan...or nobody used it, I think it was BIG$.

After giving it more thought and reading what everyone wrote, I wrote a check for the new turbo. Turns out the turbo I was looking at is a PT74GTS, not a 72. Should be here in a week or two. Can't wait! Mandy1, nice car and glad to see you joined the club. After reading about the car you had a hand at tuning, I've decided to order a set of 160lb injectors also. E-bay has a set of 4 for 200$, any other suggestions on where to buy a set?

Chuck,
In terms of injectors, I can sell you some...either the Bosch 1680cc low impedance or the 1600cc ford racing high impedance. The Bosch are slightly used and I have 2 to go and the fords are brand new still in the box. I bought an 8 pack and have the proper connecting plugs too. I can sell 4 of those. Let me know if you interested.

Wow chuck, that port is ******* huge. When the exhaust is ported like that do you do a lip around the port so that the apex seal can contact smoothly rather than slam into it and chip or is it not so much an issue? Good luck with the 74.
