turbo later. 250-300hp max. tubular front
control arms. same for the rear. also a 5lug swap and larger disk on all 4. i have alot of corners were i live and several long straight roads with no limit
I couldn't tell you if that HP number on that motor with a turbo was feasible or not. I'll let the turbo dudes do all of that.
For your
suspension, I think a 5 lug would be great! Better brakes all around and better wheel choices.
If you're serious about wanting corners you'll need a lot more than just poly bushings.
Take a look at Griggs, Maximum Motorsports, Steeda, and UPR. They all have their various methods and claims to fame. For the kinds of things that you've mentioned above, I would look at Maximum Motorsports and Griggs.
You can spend a ton of money or come up with something for less that performs well. It has a lot to do with what your priorities are.
I don't think I'd spend a dime on any of it until I had my 5-lug conversion all put together. That can change plans too when you're talking about
suspension.
One other note... tubular
control arms for the front would be kind of a waste with the stock K-Member. I do not know however, what the K-member options are for your motor. I'm sure someone will come along that does.
