I have a 1998 12 valve, 5 speed. I have a #10 TST plate slide forward, AFC spring kit, 3000 GSK, 60lb valve springs, BHAF, 4" downpipe to 5" stacks, and a PDR HX-40 turbo. My question is, I am thinking about getting laser cut delivery valves, and wondering how much it will give me, or would I be better off getting injectors first? Or doesn't it matter? Thanks!

 

get a clutch and a set of injectors

 

I have a valair clutch

 

You will be out of air with either...but I think injectors would be a better next BOMB! The Laser Cuts move a TON of fuel, and can get awful smokey and hot if you don't have a lot of air...which I don't think you do with an HX40!

I'd do injectors, put some 4k springs in your governor kit, and put some water/meth on it.

 

Sounds like good advice

sounds like my truck may run a little smokey , i have laser cut dvs anda #4 fuel plate, with a stock turbo, well until i get the 60mm compressor upgrade that is. but i have a valet switch so i can cut the fuel if things get to hot.

YOu're gonna need more charger...that 60mm is just a warmup!

yah i knew that, thats why im going to build twins after i get a couple hundred break in miles on the motor and trans, then i'll add injectors and see what that cummins can do

Now that's a good plan
