take a guess at my time

[chris harper]

I have a 86 gn with stock cam and heads. It has kb roller rockers, headers, exhaust, chip, 36 puond injectors, kenne bell fuel regulator, and a new stock size turbo. the weight is the same and nothing has been done to the transmission. What do you think my 1/4 mile time will be. Also, is anybody running a duttwieler intercooler neck? heard they were good, and found a place to get and install one for 300 dollars. Is that good ? thanks

You can find a stock intercooler with a big neck for around $150 on this board. Just post a wanted ad and I'm sure you will get some replies. I myself will have mine for sale soon.
