How much HP will the stock bottom end of a B18A1 with ARP rodbolts be good for? I want 200-225HP for a decent price without dropping $$$$ on building the bottom end.

 

your goal is reachable,if you are not tuned i would not boost more than 8psi.Im boosted LS stock block untuned putting out 200 whp on 7psi

 

With my stock turbo LS.. I hit around 260whp at 10psi. ANd 220whp at 6psi. So your goal is attainable.

 

You don't need to do anything to the motor except to make sure it has good compression. Do a search on LS Turbo or look at the huge LS Turbo thread and you'll see plenty of people making 300 whp on 100% stock long blocks.

 

Yep! (Check sig... ;-)

OP, your 2nd quote in your sig made me spit Dr. Pepper on my keyboard!

 

You have very attainable goals, but dont listen to people who give you goals in terms of PSI. That's a totally irrelevant measure. The safe range for your stock bottom end is ~300whp. Stay under that with a good tune and you'll be just fine

 

^^^ I think I've counted you saying this same thing on about 4 threads so far.. man..

 

I think I just might be catching up with Adam myself! ;-)
