hi guys i was wondering whats the max hp you can go with lq9 block with forged internals ? my goal is to reach 1100rwhp can it handle this hp or i should go with an lsx block?

notice im installing a garret gt 47 single turbo , and the crank will be callies ultra billet with callies ultra connecting rods and wiseco pistons

 

There's a few on here with stock lq4s running 800+. Smokeshow just put down 950 with a jy 06 lq4, some head studs, edelbrock proflow intake, and twin turbos at 17 psi and a few other things. So it should be doable depending on your overall setup. What are you going to do for a driveline? Cause that's going to be your limiting factor

 

Xessive did a truck went 1200 rwhp on a mustang dyno stock 6.0 block stroked to 402 and it been running for a couple of years now and plenty of track passes

 

AndysC3 thanks bro the heads will be 237 prc and abt my drivline no worries its gonna be on a nissan patrol car with modified gear and diffr. my boost will be around 22 to 25 psi with methanol and motec stand alone ecu m800 .

sammygroundzero wow couple of years for 1200rwhp lucky guy im happy for him and thanks for the info cuz i;ve read abt many recommends to go for rhs or lsx block ! than lq9 for running for long time with a 1200rwhp

what abt the heads 237 prc it wont be lifted from high boost pressure ! or water leak problems ? would i go for 4 bolt or 6 bolt head !

 

guys from the forum plz post ur feedbacks ill be happy to get more infos and ur advices
thanks in advance

 

For longevity and reliability at that power & boost level, I'd go with a 6 bolt(LSX, etc) block for sure. I've seen how you UAE boys beat the **** out of your rides.

 

hahahaha dam ur right + our weather sucks its dam too hot for high modefied engines

but which crankshaft and connecting rods ill need the callies ultra billet or lunati pro series or dragon slayer !! for 1200rwhp !!
