My question is this. off 93 octane on a stock evo 8 block is it safe to bolt on a fp black with a min of 25 psi, there is a option for 18. If i added head studs would this make a difference. im looking for a safe 450hp + car that can take the fp black and not blow it up

 

Sure with a proper tuning the 25psi actuator will be fine. Head studs not needed.

 

So i should be ok with the fp black at 25 psi on the stock engine. well im praying it dont kill the car lol

 

With 93 oct you can easy can get 450whp with that turbo and stock motor safe!

You need to contact a good tuner for that. I think 30 psi its safe with the black and stock block.

 

I will be doing the same thing most likely next week but I will be installing ARP head studs and a new head gasket, also bigger injectors.

 

im 100% stock head/block full bolt ons and an fp black... made 500 on e85 without even breaking a sweat... so 450 on 93 should be pretty easy

 

Yea dude ur fine 25 lbs is find on stock block you'll enjoy it more once its tuned
