Now you've discovered the down side to using a MHG...it triples the work. You will hear guys "get a MHG and some ARPs and you're good!"...not that simple if you want to do it right. Basically, once you decide to go with a MHG, you committed to a complete rebuild. It's a bit late now, but you...

A stock HG is fine if prep'ed right and torqued to 70-75 ft/lbs (stock head bolts) per above. What is really important for a OEM HG is head deck flatness...you actually want a std machine finish on the deck for a composite HG to provide some "grip" vs the uber smooth surface for a MHG. I give...

This is correct for the 7M. FYI the Autolite 3923's are also ISO height. What can happen if you use ISO plugs is the wires will fit, but not make a secure contact and cause an arc which will result in a misfire. The stock wires seem to tolerate this ok...some aftermarket wires do not.

LOL...so would I ;) A vernier caliper will work good enough to get a correct thickness MHG though.

Dude - if you don't do this correctly, you'll be doing it again...or, we'll get to see another Supra parted out. If $$$ is such a big deal, you don't need to be attempting this. A block rebuild needs to be very precise...all clearances checked to spec. You don't want to reuse bearings any...

And be prepared to do have the block and head decked to meet the MHG's RA (smoothness) spec. ;)

GTE tach signal is generated from the igniter. The GE is from the coil. That is correct, you can't use the GE tach on a GTE motor.

A vernier caliper of the appropriate dimension capacity.

Ummm...why would you re-use the bearings? Did you get the rod big ends checked for roundness? Did you get the crank journals checked? If you are re-using the oil pump, I highly suggest you check it's clearances. Don't be cheap or you WILL regret it.

A MHG in good shape can be reused as gaboon said. You will have to strip off the old Viton and give it a couple good coats of copper spray as a substitute.

That's a great idea...just pull a number out of your arse and use it. Base your recommendation on a whole month of use too. Highly credible post sport. Since you appear to be new guy, these kind of posts are not tolerated in the Tech section. Especially one that has potential to cause...

The best way is to weld a bung on the IC. I would use teflon tape on what screws in it.

You expressed your opinion and said nothing to back it up. Zum expressed his opinion and used what you said to back it up. Mr.PFloyd - 0 Zum - 1 You get infractions because you have a history...one anyone can see. You never step back to access you might be the one causing the problem...

Pics no workie :(

::focl:: Looked in the mirror lately sport? It's pretty obvious who takes the internet too seriously and gets their panties all wound up...your track record proves it, as does your coment in this thread...LOL! All anyone has to do is look at your profile and click on your infraction...

Thanks! You are absolutely correct...something RPSil13 (among others) seem to have a hard time understanding.

Yeah, not man enough to do that...has to go public with innuendo. He actually didn't make this thread, he continued to garbage up Doward's GB thread. IJ gave him an infraction for doing that (after I warned him not to) and moved his comments here. Freedom of speech after all ;) (Now he...

Care to qualify that...just expressing your opinion? Or, is it because I slapped you around before like I just did this boy? You do have the exact same attitude after all. Guys like you don't like that...makes their little cat hurt. Edit: I remember now...I gave you an infraction that you...

"By editing and deleting post it seems like your hiding something"...lets see here, it's Dowards thread, you directed the comment at him, followed by comments that implied that Doward was not letting people "decide for themselves". I did read your post...maybe you should read what you write or...

Head: 116mm from deck to cam cover seal surface Block: 198.5mm from deck to crank bearing saddles It's not in the TSRM...complements of IJ ;)
