Backround info:

I am upping my boost to probably around 9 psi, lookingfor near 190-200 It has a stock z6 that was freshly rebuilt around 2 years ago but has been boosted for the last 2 on a stock greddy kit. The only additions I have made are a FMIC, and soon to be Blue Top DSMs, Walbro 255 and Turbonetics MBC.

Question:

Will I need ARPs to run this setup you think? The car runs excellent on its current 5.5 psi.

thanks all.

i would suggest to run them they are only 100 bucks

 

It's up to you. Do you want to KNOW that your OEM bolts aren't going to stretch, or do you want to take the risk? I don't think 9psi would cause them too, but I wouldn't want to find out.

 

9 will stretch them a buddy just had to change headgaskets becuase his stock bolts strecthed on him.So for 100 bucks you have good insurance

 

I prefer the good o'l remove a bolt, drop the stud in and tighten method (no head removal) :P

 

he blew the gasket to i think

 

one at a time i assume?

 

I say ---- it and run it as is. If the head gasket blows, upgrade to ARPs. You'll have to remove the head anyway to fix the gasket.

 

An oem MLS gasket is $30 shipped, and arp's are $100 shipped. Get that ----, install it proper, and enjoy not having to ---- with it again - unless your tuner or wastegate sucks. :P

 

I ran 8-12 on stock a all stock z6 for a year, I had no problem until the turbo let go.
