I say change them, it's better to be on the safe side than having a hole in the block.

I got a big turbo but and am still running the stock block, the car still runs good and great but you don't know when something gonna happen.

Alot of people in evoM still running the stock block and have no problem, so it depend on you tuner really

 

507whp on ms109 at 30 psi and 425 on 93 pump 24 psi stock block and still going strong but I have an IX.

 

93 pump?
How much power are you shooting for?
660 injectors. You should be just fine with what kind of power you will make with these. I say you will be just fine to go with a bigger turbo.
What kind of turbo did you have in mind?

 

Im thinkin of FPRED or the new TOMEI ARMS,,, and about the pump gas,,, its 93oct

 

oooh I thought your going with a 35r or even bigger lol my bad man.
with your current mods you'll hit 450-480whp on a dynojet with a good tune ofcourse

Get a twin fuel pump, and some 1000cc injectors

 

Yup you should be fine, im running 35R on stock block with 83k miles 28psi.
Got a friend (Bboy) running FPRed on stock block getting 430-470hp daily. he shooting for 500.

 

My car was at 100k stock block VIII when I put the 61mm on. Running 26psi on pump 118k on her about now. 4G63 FTW

 

^^ Same here man, HTA35R running 26psi, daamn our tuner rules dosen't he :P

 

Tamer Rules

 

stock block here... greddy t67 at 23psi... making over 400 to the wheels

 

tamer (4ws) IS THE ****!!

 

I want a bigger turbo too, don't we all. YOU should be good since you got arp's in there.
