$850 good price for MHG job?

johnnyddn · 07-17-2006, 07:51 PM

I called a shop here in town called Final Stage Motorsports, they quoted me $850 for a HKS 1.2mm MHG with ARP studs. So if I did it my self the cost for parts would be:

HKS MGH = $100
ARP Studs = $120
Lapping job on head = ~$150

So about ~$370 to do it myself vs the shops $850

Not to mention I've never done anything like this before, but if I pay a shop to do this I don't really learn anything.

i would do it myself but then again i have two cars and a cousin who knows a lot about cars. i never bought from hks but i here they have a really good manual to look off.

Well if you plan on boosting the car up or keeping it reliable let the shop do it. That way if it goes bad they have to fix it. It is good to learn tho, but depends on if you think you cando it right or not. Its not THAT hard of a job, as long as you know the 7m motor well enough. Just look on the internet for some rebuild sites.And to answer your original question...Yes that is actually a good deal for the labor hours involved. Id go with it. I got a higher quote than that (1100) for all stock toyota gaskets.

MHG means you MUST mill the block too (not just the head).
There is plenty of info on the forum about the MHG install.

Bottom line...the surfaces MUST be extremely smooth, or you blow the gasket quick.

who did u get that quote from!? toyota is retarded.. i got about 1100 for the headgasket fixed.. its like, $200 for a stock gasket and 800-900 labour... but like he said.. if the shop doesnt do something right, and he blows the MHG.. shop gets to fix it.

id pay the extra and make sure its done right.

OmeGa · 07-18-2006, 06:26 PM

Since I can not really afford to have some one replace my MHG I was just wondering how long it might take me to do it myself. I have never done anything like this before and I figured the best way to learn is to do it on your own.

Isphius · 07-18-2006, 07:31 PM

Do you already have a metal head gasket in the first place? if you didnt get your head/block machined flat then you need to do that. If its a regular head gasket, And other than the MHG thing i just said, just look for the numerous head gasket replacement posts/websites. The mhg is the same kinda install as a regular one. I wanted to know tho...Is there any better gasket sealer to use or do you use any at all on the mhg. Ive never installed my own metal gasket before. Im sure youd use some kind of sealant tho...

You get what you pay for.

Cheap out on yourself (doing it yourself) which you said you have zero experiance. Vs. using Final Stage ( which have TONS of Mk3 experiance) which runs a very sucsessful mk3 drag car.

Let the shop do it. Then if something goes wrong, they are liable :?

johnnyddn · 07-18-2006, 11:08 PM

Yeah, I visited the shop yesterday and they have about 4-5 old mk3's sitting around. I heard the owner, Tony, has a MK3 putting down something like over 800 HP. I haven't seen it yet though. How have you heard about Final Stage?

Well just found out some interesting info about the place. When I went by there the shop wasn't very impressive though, but I guess the owner must know what he's doing if he's putting down this kind of power.

Turbo Tony Runs 10.2 @ 136!
On Friday June 10th of 2005 Turbo Tony broke the world record by running a 10.2 @ 136 mph with a 7M GTE motor and a 5 speed manual transmission in his 87 Toyota Supra.
This is the second record Turbo Tony has set within a year. The first record being most power put to the rear wheels with a 7M GTE motor. Turbo Tony put down 808 RWHP & 741 foot pounds of torque on May 31st, 2005 making himself one of the current record holders for most power made on a 7M GTE motor.

well.. it takes a shop about 7-8hours to do the job, or atleast the toyota dealer says. so it would probibly take a few days to do it yourself, you will want to do alot of research about it before hand aswell. you can get a haynes repair manual, at canadian tire on supra's 86-92.. i saw one the other day, there like $20cdn and im sure it will show you how to do it step by step. the main thing, is marking where everything goes and make sure to look up things u dont know. good luck, i need to do mine to.
