#1: You need the BLOCK machined for a MHG. Not just the head, but the block too. That can be a limitation if you're not doing a complete engine build. I have normally opt for an OEM head gasket on my builds because I haven't had the luxury of excess cash to dedicate to a full engine build. The...

Very cool. Sounds like you left just before I came into the scene. Give us some pics and let us know what Japanese used auto buying owning is like with a Mk 3! Sent from my Moto X.

OP, nice looking wheels. Brand new wheels of nearly any variety really clean up the look of a mk3. So many I see have tired wheels and it can really kill the appearance. My own car falls into that category as well. I just got one wheel refinished due to a bent lip and it's really made me realize...

Yeah, the 14 code disappearing and battery change could be coincidental. I also added the igniter ground. I'll keep this thread updated, but so far it seems incredibly coincidental that it has started 100% now and before was somewhere around 75%. The STA thing is still strange. I measure just...

Head Bolt Torque specification in combination with the head gasket material was a fault, yes. In their defense, however, the cars still lasted a solid 100k-150k miles before a problem occurred. Not exactly an obvious fault when it takes most cars 7-10 years for the problem to surface. Mine...

Toyota engineers put more research into the 7M oil cooler circuit than any forum member I've ever heard of. I think a lot of folks underestimate the resources that go into OEM equipment. Equipping the 7MGTE with an oil cooler circuit cost Toyota a LOT of money. Likely millions upon millions of...

Haven't driven it for a week while I get a bent wheel and my power antenna repaired. The battery seems to have solved the 14 code, but 43 still shows up every crank. I'll update again once I start daily driving it again (Hopefully within a week). Are those your only codes? Sent from my Moto X.

Thanks for the explanation. That picture really helps. Previously I'd only seen them installed and it just looked like a countersunk collar, similar to what OP posted above. I can see how that would help keep the aluminum from collapsing and compromising the clamping force if it were press fit.

Call me dumb here, but I have never understood this practice. Here's my understanding: 1. Using the studs without any modification, you have a washer underneath the nut. The washer distributes to clamping force over the area underneath the washer as ARP designed it. This is also where Toyota...

Dr tweak is a great source. I had to get many of my plugs through random online vendors. Dr tweak, eastern beaver, digikey, Newark, and go figure the toyota dealer. Sent from my Moto X.

Update: With the new battery it's started everytime, no problem about 14 times in a row. The failure to start seems to have been battery related. I still get a code 43 and I need to troubleshoot that, but it's functional now. The idle also seemed to fix itself after the first two days of...

Yup. Keep an eye on it and run it as is. let us know how much it'll hold and for how long. haha. If you've already torqued down the head I wouldn't reuse it. MHG? sure. Composite? no.

That 60 mile commute sounds like an excellent opportunity to give the car the time needed to justify keeping it. Plan on a Friday commute in the Supra once or twice a month or something. Make it a special drive once in a while. I'll add that if you reach a point where it's no longer special or...

You'll regret the sale. If money isn't a concern keep it and pass it on. A mk3 supra that clean and powerful is rare and a steal at 15-20k. If money is a concern then selling makes sense. Sent from my Moto X.

Do you want to run higher pressure because you're concerned the factory pressure isn't sufficient for your power level? I ask because many people see the stock gauge and its relatively "low" pressure and think something must be wrong or that they need to significantly up the oil pressure. The...

I'd say that's a great deal. That's cheaper than some junkyard prices. For that little I'd be ready to rebuild it right away. Sent from my Moto X.

Yup, that's mine. I'd like it to turn into a mk3 dictionary/encyclopedia of sorts, but it's just in its infancy now. I'm not a programmer or software writer so it's taken some time to figure out the html code. Grand ideas are one thing, but putting them into reality is another beast. I've done...

One thing they could have done is make the mounting nut on the backside a fixed nut (welded to the body). This would require the strut studs to be bolts, where they are now currently a fixed stud. I'm not sure why Toyota opted to design it like they did, but I have a feeling it's due to common...

Incomplete, but full of pictures: http://yotamd.com/toyota/mk3_supra/hatch_struts.html Basically you have to remove the entire rear interior to do it the way Toyota intended. You can pry back the trim and sort of get to the nuts on the hatch mount, but it's painful for your hands and you might...

Yeah, it's a clean machined face under the factory clear coat. It will be less protected though so that nice machined look may not last...
