A few questions:

[trydrew]

Hi everyone,
Im pretty much new here and new to the supra community. I wanna say first off that i am only 17 yrs old... Dont be hatin' :icon_bigg No, i am mature when it comes to cars (they all need tlc) and have been interested in them for a long time (considering my age). I like working on them and that is why i got a supra. im a toyota fan anyway, so it worked out.

Right Now though my car has a BGH. Since the engine ran fine all the way up to when it happened, im hopin a rebuild wont be too dramatic. My car has been swapped to a 5-spd by the previous owner. It was done ok.

What i wanna ask is what you guys think i should do with the HG (MHG, stock) if im goin for more of stock component that i want to last. I plan on ARP boltstuds but im not sure what gasket to get... i know i need to see the shape of the head and deck first but i wanted a general consencious...

Thanks, Drew

Drew.

First welcome.

The BHG is a big problem on our cars.

Please use the search button on this topic.

There are several types of HG you can get. Metal layer, copper, etc etc etc.

I personally like the Commetic. Its an all steel design, and has been proven to hold over 1000hp with out any problems. It has its drawbacks though - It likes perfectly prepaired block and head surfaces.

Good luck, hit that search button!

Cheers! (Like ROY)

Welcome Drew..........
Do you have a NA or a turbo?

As far as a minimum rebuild, I did and would recommend something like this:
I would recommend tearing the engine down.
Crack check the block, head and crank. You don't have to do this but it would be a bummer if you rebuild the thing and something was cracked so you have to tear it all down again after a year or so when the crack gets real big.
Resurface the block deck and head.
Valve job and adjust (reshim) the valves.
You might want to do a port and polish while the head's apart, but not necessary.
New oil pump. (I didn't do this and regret it)
All new gaskets, belts and hoses. I didn't use new intake hoses. If you use the old stuff, you'll end up replacing things as they go bad right after you just tore the whole thing down. Two years after I rebuilt mine, my intake hoses leaked and I failed smog, which lead to another thing and something else which finally lead to my motor being have to be rebuild again and the car has sat for three years now.
New water pump and fan clutch (if you have one). Don't really need the new fan clutch or water pump but while the motor's out you might as well change it when its real easy.
I also recommend a new wire harness. Its not necessary but it would be better. You could have problems after you put everything back together because of the old connectors breaking or not making good contact.
Send the injectors out for professional cleaning and rebuilding.
New bearings.
I went with a HKS gasket.
I also bored the cylinders out and went with forged pistons and new rings.
I think that was the bulk of it.

Whatever you do, make sure the engine repair is done right. Or it will happen again.

Wow I'm amazed!

Good post Drew a few minor terminology errors and a couple of spelling errors but you're already so far ahead of most of the recent young guy posts!

As the guys have said do it right do it once and you'll enjoy your car and never be scared to ask if you're not sure of something the guys here are all willing to help out.

Hey guys im travis im 16 also new to the supramania forum i bought my supra about a month ago. first of im replacing the clutch becuse its worn out and i am wondering im thinking of going with a stage 2... the research i did said a stock hg should be ok for that amount of power but i was getting a second opinion. im checking all the vacume lines for leaks and such i just need to know if is should upgrade my HG. And also i totaly agree with you guys and drew there are to many kids watching to much fast and furious and then wanting to go out and be a street racer. my dad has worked on cars since the 60's and thats were i got my love for cars and i new that the supra could feed my hunger for them anyway i am going of topic um ya so what do you say about the HG upgrade YA or NAH

I'm not sure if you meant to say "the research i did said a bgh should be ok for that amount of power", but a blown head gasket is never ok. If you do have a BHG, repair it. I recommend to evaluate the current condition of your motor. Find all the leaks & fix them, do a compression check, replace the vacuum lines, reduce any codes you may have, et al.

If you need to find info, you the serch feature here first for two reasons. First, to put it kindly, you'll get flamed. Second & most importantly, you will learn a lot more when you attempt to do it yourself. You stumble upon something you weren't looking for & but you'll end up needing later.

If you can't find something, by all means ask questions.

Welcome Drew.
Thank you for your well composed post. It's really helpful to us to see paragraphs.

Travis, look at drews post and try to organise your posts like that. Take a while, search about clutches headgaskets etc. And then post a New Thread like Drew did.

Back to you drew,

Hi everyone,
Im pretty much new here and new to the supra community. I wanna say first off that i am only 17 yrs old... Dont be hatin' No, i am mature when it comes to cars (they all need tlc) and have been interested in them for a long time (considering my age). I like working on them and that is why i got a supra. im a toyota fan anyway, so it worked out.

You've got the right car if you enjoy working on it! You'll find that as long as you take great care of your supra, it'll take great care of you.

Right Now though my car has a BGH. Since the engine ran fine all the way up to when it happened, im hopin a rebuild wont be too dramatic. My car has been swapped to a 5-spd by the previous owner. It was done ok.

It's great to know the history of your car, did you know the previous owner?
My personal recomendation is to pull the motor and do a complete teardown. Save anything that is in good condition that is not a wear part. Replace everything that is a wear part (piston rings, bearings, gaskets, etc...) Also get familiar with Cygnusx1.net, It is a HUGE resource to us. Check your oil pump per TSRM, and replace it if needed.
One thing to take into account is mileage, Also whether or not it's turbo. I'm assuming that it is, since someone went through the hassle of swapping in a manual gearbox. If mileage is particularly high, then you may benefit from some new pistons. I'd recomend Je for high horsepower applications. If you are to use a non-forged piston, I would only use an OEM piston. Aftermarket high volume/ low cost pistons cannot handle extreme conditions. Just ask Ian..

What i wanna ask is what you guys think i should do with the HG (MHG, stock) if im goin for more of stock component that i want to last. I plan on ARP boltstuds but im not sure what gasket to get... i know i need to see the shape of the head and deck first but i wanted a general consencious...

It really depends on what your long term goals are. A metal headgasket is just as reliable as a composite headgasket if the mating surfaces are machined right. If you really think that you're not going to get bit by the boost bug when you do little things like intake, exhaust, downpipe, etc... Then stick with a stock gasket. If you think that you'll want to turn the boost up with an aftermarket turbo, then I'd recommend going with a MLS headgasket. In reality, most multi layer steel gaskets will all handle the same abuse when installed correctly. Cometic makes a great gasket, but if you search, you may notice that you'll need to grind a rivit out of the gasket for it to seat correctly. It is the cheapest option by far, however. Greddy makes great gaskets, hks, titan... They all work great when installed correctly. MHG failure is 99% user error.

Thanks, Drew

Thank you for posting clearly.
Again, welcome to the site, and use the search button. Just browse through all the topics that you have questions about, it'll answer questions you hadn't even thought of yet.

welcome drew. always nice to see another supra owner. no matter the age. just respect it. whether you use a stock or a metal HG. do upgrade the head studs and torque down the head a bit more too! good luck with the rebiuld.

hey drew,
amongst all your searching you might want to check out a thread titled "well i found the limit of the stock hg" by grimjack. he was running 20psi on a stocker torqued to 90 or 100ft/lbs i think. just to show how much the stock hg can take. you should probly start thinking what your goals for the car are, a million hp vs just alittle above stock hp. but i guess if your doing a total tear down so a mhg might not be that much more work, just mill the head and block. but if you are only going to pull the heads i would recomend the stock hg. might also want to look into shimming the oil pump.

good luck to you. your going to learn alot if you keep working on your car and hang around here.

Pinkiscool: Not a bad effort as well, add in a paragraph or two spellcheck and you're golden!

(You and Drew have made me smile there is hope for this generation!)

(You and Drew have made me smile there is hope for this generation!)

Agreed. There's a light, albeit dim, at the end of the tunnel. :biglaugh:

Hey, Thanks everyone for all the input on my crisis…

IJ: About my grammar, I don’t remember where I read it but someone said that the best first impressions on forums involve good use of words. Always has been important… lol. Btw your thread has got to be the longest I’ve ever seen.

Anyway, I’ve been reading here for nearly two months and read about Mk3s way before I ever bought one. Id like to say I know a fair bit about them, but u guys would prove me wrong right away. :icon_bigg

My goal for this car is more of a daily driver type, reliable but occasionally fun. I think that I am just going to stick with the stock HG, considering I don’t think I’m gonna be pushin’ anything other then stock boost, for now. :evil2: lol ARP head bolts are definitely on the parts list too.

IHI-RHC7: Thanks. As it turns out, Cygnusx1.net was the very first site that I put when I started compiling a SUPRA favorites web-sites list on my pc. I dont know how I found it but I was reading off that way before I bought my car and am still amazed by the TSRM on there.

 

[trydrew]

A few etxra pointers... My car is a '90 turbo with a cat-back exhaust (not sure of size) and BBS rims ( 16's... not my choice) with Dunlop sp tires. It is also a A340E->R-154 swap. That is essentially all the performance type mods on my car as of now.
A little more history - My car was wrecked when the second owner bought it. The rear fender and a small part of the front fender were cripled. He bought it because it was highly repairable, just totaled. He was a mechanic and it was him who swaped the transmission. Bought it for $2700. There was no problem at the time that we knew of.

One more question:
When i got my car (prior to BHG), i realized that on first take off, but not much when driving (cant remember exactly), there was a clicking noise coming from upfront. It went like, "click...... click..click...........click", and so on. It doesnt worry me much and may be normal. I have ideas on what it might be, but does any one else hear this?

 

[souprat]

valves? i know thats usualy a constant tick,tick,tick but i'm just throwing it out there.

 

[trydrew]

Its not costant, but random.
