Just picked up my first Supra

[bryan163]

I just picked up an 87 mk3 on saturday. Its a turbo targa. I paid $750. The previous owner had run the car out of oil and put a rod through the block. I already have another 7MGTE on the stand that I was given by a friend. I pulled the head yesterday and have an HKS metal head gasket on the way. The body is nearly perfect, but the clear coat is shot. Gonna paint it after I change the motor. I've been browsing the forum for a couple days and figured its time to say hello.
Here's the car being delivered:

Midnight blue's a nice color.

Congrats on the purchase, make sure you take care of the main things, or it'll nickle and dime you to death...

 

[bryan163]

Thanks. I'm gonna go thru it and get it how I want it over the next few weeks. Then Its on drift rotation with my other car.

make sure you get the head and block milled to a ra of 12 or lower or that MLS wont seal

 

[bryan163]

Thanks. I hadn't planned on doing any machine work, but I will look into finding a place to do it tomorrow. Any Idea how much they will charge?

 

[kotu100]

depends what you need done, but i'd put aside about $300 for the bare minimum.

 

[bryan163]

I guess this means i have to strip the block and head down the bare castings? The motor was recently rebuilt so I was gonna leave all that stuff alone, but im sure the reason the head gasket failed was because they didnt do that the first time around.

nice and great price also i got mine for 500 but its ge, i think your supra is the first one on here that is the same color as mine lol

Really? Is midnight blue a rare color? I was considering painting it black, but maybe I should keep it original. I have an 88 thunderbird that appears to be the exact same color and it is also called midnight blue.

Not really, rarest colors are teal and pearl brown, each were single year colors.

thought i had a special color

Can anyone tell me if these are stock pistons? I know this motor was rebuilt, but I don't know If they changed the pistons or just the rings. I just sold one of my other cars so I have some money to sink into this motor. I'm not really sure what the stock pistons can handle, but I'm thinking since I have the motor apart I should build it to handle more power. I'm definitely gonna grab a larger turbo now and would like to run around 16psi.

 

[Zumtizzle]

Those are aftermarket.

 

[bryan163]

Hmm, I wonder if they are just a stock replacement or something better.

 

[kotu100]

Those pistons are .50 over so that engine's deff had some work done to it.
If you pull the pan and shine a flashlight to see the underside of the piston you might be able to find a casting or stamp of the manufacturer.

 

[Turbo Habanero]

.50 over doesn't really give you much room to go bigger if you had to.

 

[bryan163]

I shouldn't have to. There's hardly and miles on this rebuild. It look like the head gasket blew right after the rebuild because they didn't machine the mating surface to the required RA 12 smoothness. The gasket that was in there appears to be the same HKS gasket that I bought to replace it.

 

[bryan163]

Here's a shot of the gasket. It looks to me like it was leaking between cylinders.

 

[jake8790]

Not .050 over
.50 millimeters over
which is .020 over

 

[bryan163]

I thought that seemed like too much for an over bore. I'm not very well versed in engine building. whats going into your build Jake?
