^ What he said. Swapping in a different model engine is never as simple as it's sometimes made out to be.

Hmm Well how much would It cost to fix a exhaust leak/new turbo... turbo is about 500$ ... can you fix a manifold leak?... I dunno if the damn block is stripped or what.. the shit looks rusty but I dunno if I want to fuck with it more and make it worse?.. I got the time and tools to tinker just nothing to major.. 2 days of free time.. hmmmm i dont need powersteering..
my tranny just started makeing some weird noise today like the damn things running dry or something... no clue ... bleh I think I would be Sinking money into a black hole on this than on A replacement With any diffrent problems!!!

mine Runs Great... Everything else is Shit!!! plus starter relay is intermittant
so youve deterred me from a swap for now... till I atleast pay this thing off.

Exhaust manifold leaks aren't unknown on the 7M. In fact, if I remember correctly the relative softness of the head allows the EM studs to back/strip out eventually. That could well be the cause of your exhaust manifold leak. One of the better aftermarket Supra parts suppliers stocks a replacement stud kit for this, works like a charm and is under $100.

That leads to the question, are you certain the leak is at the manifold and not at the elbow or other gasketed joint? No matter where it is you'll want to fix it before you run it again or the exhaust gasses will start eroding & possibly cutting the surfaces, making sealing the thing back up difficult without some machining work.

You can get your turbo rebuilt for less if money is an overriding issue. There's a place in Canada I sent mine too a few years back, they did a good job on it for about $300. Blast Performance I think the name of the place was.

And don't let us talk you into or out of anything. We're simply making some observations and presenting our opinions and the reasoning behind them. Only you know your exact situation, how much time & money you're prepared to put into the car.

Yeah, helicoil kits; Some of which accept the stock studs some come with new studs. BTW - They're a miserable HELL to install with the head still on the engine... I do NOT recommend trying it. Get it in crooked or crack the surrounding metal and you're really hosed. /disclaimer

I've never experienced any trouble with a stud pulling out, but it is common. Make sure you don't over torque the studs, it'll help with the longevity and durability of the threads in the head.

Agreed.

Found the kit I was talking about, as luck would have it it's a Drift Motion set...

Haven't used it myself, but several people at SupraMania who have gotten it swear by it for taking care of pulled studs. I don't remember how many of them attempted the repair with the head still on the engine though.

A few, the rest learned from their mistakes.

well Im a Marine So I mean I can Buy what I need... Im not rich but I do pour my heart and soul into this car.. lol Its my shitty car dream.. and the car just needs to be put into my garage and Rebuilt ground up.. the harness scares me suspension blow.. rear calipers seized I just redid the Brake lines cause they were rusted.. new interior redid the guages, snapped the speed cable due to the line holding the cable Broke and was bending the cable

Its a Good motor just Every small thing that could need replaceing Does.. haha... I think the tranny has a Leak?

Ok Well I look at it this Way my Subframe Fits a 1jz 90 7m my friend has a 89 and basically Told me all the wrong things he did.. and helped me plan out my swap. If I do a swap basically everythings Compatible BUT Id need to rig up something for the intercooler and Exhaust... other than that its straight Forward buy the motor... and some general stuff Timing oil oilfilter and hopefully the coils are good. then just hope the new one has powersteering for comfort and call It good for 6-8 months till I can Redo all the cooling and breathing factors of the motor... Im looking at these numbers

around 1500-2000$ to Fix My current nightmare... or b 2600 to get the 1j in and maybe another 5-600 to get a custom exhaust and intercooler I found a intercooler for 100$ new from a buddy for a 1j and I can Make my own Exhaust the weekend after the swap I know a Fab shop has tons of extra piping.. Cut weld my own 3" up call It all A Great cheap quick job put a bic and Tip on it later.. .

Im just really stuck... I think my car is getting like 12mpg with no turbo llol plus I have NO power its annoying... I can take out a small Loan To get one or the other project started... btw this is my First supra and wont be the last hopefully a mk4 will come in 3-4 years ill buy something more complete lol not a halfway shitty project car..

thanks alot for the help so far you both have given me some things to think over I know Those Studs Are notorious for probs I can look at them and play around with my manifold Im 100% sure its leaking at the block I felt around.. Its been driven like that for awhile... not Too long ... one oil Change?heh .... wasn't worried I was thinking I would swap the motor.. btw i'd rather just buy a new turbo if i was to keep the 7m
