HP Upgrade time

[Supra_87_mk3]

hey, i have a 89 7mgte and a blown head gasket, so i just bought a HG off of HPF.com and it should be comming any day, its really thick like 1.71mm so compression will be down to 8-1 wich will be good. my next prob is when im doing the head job i think i should install a boost controller but i dont know what kind to go w/.what psi should ARP studs be added i'm only planning 15 to start prolly 20 MAX.(this 15-20psi is after i make sure everything is alright and working good) i just know the arp stud install is a hastle and i would like to avoid but if it is needed its needed, b/c the 7M head job isn't fun eather.

i feel like it can handle the 15psi b/c i have changed ever aspect of the cooling system, and got a BOV (no real help but looks cool ) intake, cat back.strut bar coil overs, and like i said soon MBC and turbo timer. anything else to do b4 i do this?

lol wow. Anyways, first off, what kind of hg did u buy. Second you need ALOT more gaskets than just the hg. Third arps are easy to install and technically if your doing the hg you shouldnt re-use the stock head bolts. There likely to stretch and result in another falure. So buy the arp's anyway. Fourth, if ur hg is 1.7mm thick, its most likely a metal hg, so you WILL need to send your block and head out for deck'ing. Fifth, dont go with a mbc get a electronic bc. Greddy profec's are cheap and even spec 2 profecs arent that expensive. All of this info could have been found in ihatehack's bhg install thread. I recommend finding it and studying it. This job is pretty staight forward if you know what your doing and you do your research.

i dont think you realize that im not retarded i know that you need more than one gasket i have the gasket set i wanted an after market HG to lower the chance of it blowing. and yes i am taking it to be resurfaced.. also i have done this head jod on a N/A 2 times and i do realize they are stretch bolts and will be replacing them. all i wanted to know is do i need the studs also, for 15 psi, and what kind of BC is good... (no Disrespect, but im not that stupid).

I went with ARP studs and I'm just an na. I also went with the HKS stopper 2.mm MHG. I have an upper gasket set wich I am sure will not have totally everything. I definitley want a toyota oem exhaust manifold gasket.

[Supra_87_mk3]

ic. well the last gasket set i ordered didn't have the manifold gasket so beeing that i work at autozone i had it the next day. but you do feel that the studs will really help?b/c i bought this car for $2,000 drove it home on the 45 min drive it over heated. i knew it was prolly a HG but i hoped for the best. i replaced all the cooling system conponants and still overheat. so i know 90% it is the HG.. i did a block test but it seemed to pass. it didn't turn green. (i had just done a flush before i did the test if that matters) so i've spent about $2,500 so far on cooling and the car. i also bought the BOV coil overs, tail Pipe. wich brings me to about $3,000. so i am low on funds right now and would still like to do BC and Turbo timer.

Alright there is a big debate going on with ARP absolutely being an urban myth.

I personally feel like I want to get as close to bullet proof as I possibley can. You also have to take your driving style into account.

I could have bought brand new toyota oem head bolts and didn't because I want the security of a studded engine. The 350 dollar mhg and the 100 dollar arp's do not mean I will never blow another head gasket. But I think I have decided to torque my studs down to 80 lbs.

I wouldn't want to risk that with new oem head bolts. The threads will strip sooner or later.

I payed 2k,700 bucks for my ride. I put 3k.500 miles on it and it has been parked every sinse. In the last 2 weeks alone I have dumped 3k into parts for this car and still haven't gotten to the brakes.

So I feel your plight. I say why risk it by not going ARP studs or bolts.

Just my opinion and there's a reason it's free.

Dude you NEVER know. And im sure a few people can agree that the way you worded your first post, its sounds like you would have issues doing valve cover gaskets. And you have 18 posts. Which tells me you havent been here long. So dude you never know, no offense intended.

[dcrusupra]

You still have the stock turbo right?

Sometimes the best thing to do is break it down so small as if you don't know how to do it. It's not a sign of disrespect. He was just trying to help you.
