Changing BHG. Anything else?

[Sonyps307]

If u get silicone hoses then I would use something like zip ties at each end. I have the silicone kit and I kept getting leaks and some would blow off so I used zip ties. I would run a straight 3 inch from turbo back 4 inch is a little over kill. If u got stainless steel then it would never rust but costly.

do u have a link to the kit u bought?
Did u notice any power increase with the kit at all or is it not even worth it?

[Sonyps307]

They sell a kit on eBay but I got mine from my auto parts store (pepboys) 30$ it came with 3 sizes and I just cut to fit. As for power yes I got some power back but my hoses were original so I think I had a leak.

Me and my friend didnt go with a MHG because we didnt shave the block. My question is did we make a mistake by no going with a metal one? I was reading that some ppl dont shave the block and other say that you absolutely have to get the head and block shaved. I was reading suprra_girls thread on steps to modifying your supra and i would love to do a lot of that stuff but idk if i should without a MHG. We did torque the headbolts down to 90psi though.

The stock hg is good to around 12psi from what i've heard, but don't hold me to it. But I believe the two reasons to get the head shaved are because the head is not flat enough or to make a smooth surface for the mhg since it needs to be as smooth as possible. So as long as you made sure to clean the surfaces and threads well then you should be fine with lower boost levels. But as far as your torque spec, I assume you mean ft.lbs.. Did you use arp head bolts , because that spec seems high even for them? I did 90lbs on my studs with the moly lube. Also did you follow the patten for tightening and do it in three passes?

[icey756]

yes. 3 passes of 30, 60, then 90. Arp head bolts. We already shaved the head when we put the new stock gasket on. Im just wondering if I would be able to do the stuff that suprra_girl has posted in her sticky thread on the stock gasket

[icey756]

Is it true that after 1000 miles i should retorque all the headbolts? i remember seeing something about it but i just dont see why i would need to if they are already at 90fp

it cant hurt to recheck after doing that big of a job. thermal expansion and vibrations can cause a small amount of loss, so checking them after a break in is a good check up.
