I got a b18c5 with 81.5 mm forged piston i push 10psi @ 327whp i want to up the boost around 16 to get around 450whp for my second boost option (dual boost controller) sorry for my english

i have see for 650$ vs 1200$ MID sleeves

Darton Sleeves Repair (Guarteed 20psi) and stay open deck and darton use another metal material suposed to be moore hard to broke

10mm moore big then stock sleeve do you think its a good alternative for the WHP i want

 

Ran 19psi stock sleeves. Would boost more but no traction. No reason to sleeve. 81.5mm got a block guard but you really don't need it.

 

how much horse power i can put on the block 9.1 cp + gt30

 

It all depends on the tune. I wouldn't try to push past 500whp.

 

ok soo i will try the next summer my second boost it will be around 427whp 1 stage at 327whp and the second i hope it will be overkill if i use this one if i broke i will change for someting like repair sleeve or MID sleeve

soo all question its because i need to do a ring job sooo i see all in my rearview i can wait again

 

If you're looking for 450whp, stick with the stock sleeves. Aftermarket sleeves would give you peace of mind that nothing is going to happen, but they aren't necessary by any means. I'm actually looking to make right around 450whp myself and i'm on stock sleeves with a higher static compression (9.8:1)

 

have some thing to chek to be moore safe

i cant put a BG because my block is already build
