Yes the helicoil's inside diameter will be the proper size....so yes you'll be drilling and taping a larger hole. The tab is best broken with a quick blow....you may be able to use needle nose but do not pull on it...just twist it! But you need to do it fast...the kit comes with a punch made...

I'm busting your balls man lol.....but seriously don't go with nvs<----gay!

With all due respect this thread is annoying....your car is damn near stock and slow....it's nothing to envy and it's not going to kill a v8 that's worth a damn...although it is a very nice supra indeed and is currently faster than "both" of my supras....but your ideas make be believe one is...

How about "ur m0m69"....

This is all you need! Comes with everything....it's a bit pricey but it has extra coils on the "just in case" situations.... http://www1.mscdirect.com/CGI/NNSRIT?PMPXNO=1648924&PMT4NO=69831724

You'll need the tool....as there is a tab on each coil that bends toward the center, this tab needs to be broken off after instalation....I have a special spring loaded tool that snaps them in a jiffy but it wasn't very cheap $20 or so. The helicoil kit should atleast tell you what tap is...

Indeed I agree! But sometimes shit in one hand and want in the other and see which one fills up first:-( timecerts and helicoils will prevent that from happening which is why I personally recomend the helicoil as it's an easier product to use for this application "my opinion"...much more...

Timecerts are better....but you need to have enough material around said hole to install them or else you can cut into some other part of the housing and cause a leak or whatever....hard to tell which bolt he broke as there is no pic so I or us can't really tell him which route to take....some...

A helicoil is like a spring but yes you need to tap and screw the coil in and then you'll have your original thread size...helicoil is a pretty strong design...some of the parts we make at work get helicoiled by design!

Keenserts/timecerts are a little more involved and require more material to be removed...if there isn't much wall thickness from around the pump then a timecert isn't really an option....timecerts generally are something that needs ordered as well as helicoils unless you have a machineshop...

So bottom line is...if you're going to helicoil then purchase a kit that includes tap and drill.... If you're just going to retap then let me or whoever know what tap you're going to use and I/whoever can tell you the proper drill size for said tap. Tap and drill sizes are not exactly...

It all depends on the tap as to what drill bit to use.... For example a 7/8-9 tap requires a 49/64 drill a 7/8-14 tap requires 13/16 drill if you do a good job drilling out the broken bolt then you may be able to helicoil back to the stock thread size...if not then you'll have to tap to...

What? Can you go into more detail of what exactly you mean?

Lmao!

just for you ian

Lmao....damn you ij I was hammered when I took that pic lol

been cleaning the block a bit... dread fixing this mess cant seem to get a good picture of the block surface....its smoother than it looks but im not near done.

Yes you want to lube them with Vaseline...when you put the injectors and rail in you'll want to rotate the injectors side to side a few times to ensure a good seal.

Can you load it on YouTube so I can view it as I'm on my friggin iPhone:-(

This is a very very very common problem with these cars! The bolt and the bushing have corroded and bonded together! Usually you need to cut them out with a sawsall or torch...you can try some PB blaster but usually it doesn't work. Sorry bro but consider yourself dealing with a problem...
