Rod knock?

[Epy]

Well I called up revmaster machine today...

They want 1,100 to do a port and polish, take the valves out, shim them, 5 angle valve job, re assemble it and hot tank it , they want 1,100.

They don't do sonic cleaning there...
I didn't ask about decking and the whole torque plates because I don't really think I'd need a deck... it only increases compression, correct?

Incorrect, read the manual.

Didnt you read what was already posted in your own thread?

Im on my last leg here. If you want a MHG to seal you need to make sure the surface finish is less than at least 30Ra. It wont increase compression because you choose a headgasket that will keep the compression at stock or close to it, thats a reason they come in different thicknesses. If they shave off 0.3mm off the deck of the head add that to the thickness of the stock gasket. Port and Polishing isnt cheap, some people do mild DIY port and polishes. The stock head is fine as it is and has been taken to 550+hp, it will help but you dont HAVE to do it. If you plan to bore the motor out a torque plate is a good idea.

Please Search i just did and got a crap load of threads that answered these same questions.

 

[Epy]

I'm not saying using a metal head gasket...

yes I searched too and all I see is that if you deck it, then it reduces the size of the combustion chamber, it increases compression. That's the only thing I've found..

For a port and polish alone, they want 650.

 

[JDMMA70]

Regardless, if you plan to use a MHG which you WILL for the power goals youre talking about you NEED to have a good surfaces finish so you will need to deck it. Lapping is also an option but i do not know the specifics on it.

Im not quite sure you know what decking the block or head means. In any case search.

 

[arizzle]

yea and I changed the HP level after I realized it was way to high. I had no idea what supras do and what it takes to get there... rather, I had higher expectations for a supra(Mk3 persay)

Your still not understanding my point... I don't care where you've came from or what you've driven.. I'm telling you my scenario and that's why I assumed the crank v. piston position... I understand that it was wrong and your still going on about it...

For the 2nd time, I have read the sticky... don't tell me I haven't , if I have... LMFAO

So if you think I'm doing everything wrong... here... why don't you take the one minute out of your time... put yourself into my shoes for exactly 60 seconds and write-up and tell me WHAT YOU would do in this situation...

The head is off with only the valves in...
I have 3,000 dollars with plenty of time...
I want turbo...
Have the block seperate also...
where would you go? Just curious...

well i've read this whole thread! oh man!

but if you have 3000 dollars and a motor apart i would just use it to get it back on the road! if you was 300whp and dont want to spend more i would just fixing you bearings, deck the block and head slap in, buy a CT26 with manifold and safc. i would do a complete GTE set-up with your block since its out already. thats what i would do with 3000 and time!:naughty:

dont waste your money on a port and polish when you can take the time to just DIY!

 

[grimreaper]

DONT DO THIS YOURSELF! have a basic head job done, new seals replace any burnt/ bent valves, re shimmed, decked and hardness tested < do that first, if its soft, its trash. You can get decent remaned heads for $450.


when you deck the head and block, you do NOT use a stock thickness HG. You will use a thicker one to replace the material that was removed and in turn leaving you with STOCK compression if your math is correct.

Thank you.. now that's a wealthy response.

No, I am not going to do the PnP, or even a mild one, that's retarded at my skill level.

Well I'm still searching though, I've been referred by a guy with his 2JZGTE drag car in a 71 datsun at the local track he runs 8.6's and is pretty known to a machine shop that completely built his engine, so I will be calling them up, since it's within the same.. like I know it's not the 7m, but I'm sure they must be familiar with them, also they have a good reputation. His name is mike (z-gad)

 

[AJ'S 88NA]

Were are you at in Florida? I know of a good shop that did my machining.

Alright well I called up dover... the other place

They want approximately 3,500 in labor, a few days for taking the whole motor apart, PnP'ing, boring, honing, decking to spec, disassembly, reassembly, and figure out why they spun and what bearings would need to be put in and etc.

They want 200 just to dissemble and look at it, to give me a definate quote with what parts I need, what size bearings, etc. and labor put together, but once its apart, they can't put it back together if I don't have enough money, everything would need to be machined, so I was like, ok so If I don't have enough money, what happens? He's like well... you should know if you and if worst case scenario comes we hold onto it for you and if you tell us eventually you can't... then we give it back to you the way it is... (in pieces)

So basically I'm screwed... it looks like it'll turn into a parts thread if I can't find a good running motor that I can buy and just swap in, because I don't want the car just sitting around.

so have taken it there yet and let them take it apart...or did you just call em and ask?

3500....that sounds like a trap...I've seen it done too many times.

"OH yeah we'll check it out for 200 bucks, and they'll tell you a big 'Ole list of problems."

Then they'd try to make you think the car ain't worth the effort. Then they would try to buy the car from you and slap a 600 buck motor in it and sell it for 3000+ bucks(depends on how good the cars condition). Or you would pay them 3500 bucks to get it fixed and they would still prolly screw you over. They would make money either way. I don't even trust family mechanics. I trust my self and a good machinist who can show me what he has done and explain every bit of what he had done.

my first car rebuild was a supra and i did it, i knew NOTHING about cars.

lol, you can buy a 7mge on the cheapo. like 600$ ish.
i bought my black supra with rod knock for 1300 and spent 1700 to buy new seals, toga oil pump, greddy metal head gasket, new 7m standard crank with bearings, water pump, alt, timing belt, belts, machine work(decking both block and head, new freeze plugs, block and head cleaning, and honing) and a lift. lolz man, i wish i could rebuild engines for 3500$. I'd be balling! :sarcasm:

+1

$3,500 seems like a lot. Bluechulappa on the forums only spent around $900 to have the bottom end rebuilt that included all the machine work. It can be higher depends what else needs to be machined. However once again i ask why you are getting a Port and Polish done.

Heres what id do. Find a torque plate or borrow one from someone. Disassemble the block yourself, being sure to label everything. I mean to machine just my block it came out to around $500 on the quote which i had them give me a head of time. Itll end up being cheaper if you assemble the block yourself. However if youre not confident in yourself that you cant do it, then dont.

 

[dumbo]

he does wanna go na-t so the budgets is a bit tighter for him.

 

[Epy]

Alright.

So if I disseamble myself, and just get the machine work done, like, hone, bore, deck, PnP(if I want it) for alot less. btw, by bore, is that just redoing the walls, because I don't want it bored over .020 or 40 or w.e, I want stock.

Then I reassemble myself?

I honestly I'd have to say, I don't know if I could trust myself. besides, after I reassemble it, I would want it balanced, so would I just bring it back? Also, the bearing shouldn't have just spun, it's gotta be checked as to what size bearings I should go with, like if they should be o/s or what happen. Also I'd have to buy a new high pressure oil pump

Alright, I'm glad I told y'all, I wanted to know if that what prices go for. After you guys telling me you can get it for 1700 and 900, I guess I just got to keep searching. Also, I'll send it off, if it's going to shave off a 1,000 dollars with the same work, at a shop with the same reputation.

See around here, dover seems to have the best, along with another one called the auto machine shop, I'm going to call them tommorrow. I'll keep you informed...

 

[JDMMA70]

High Pressure Pump? The 7M's oiling system is a low pressure, high volume setup.

When it comes to assembling the motor you need to be very careful and make your measurments accordingly. Following the TSRM is a good idea as it was posted in the thread multiple times. For balancing it needs to be done before the block gets assembled. Make sure you have everything you're supposed to when you send it to get balanced.

 

[BlackDynamite]

just poking around, found this. This would save you time if you stay NA and get you back on the road. Then you could build your old motor and take your time on it.

Just as an idea.

Buddy bought a Honda motor from em. Still running good.

A lot of people are against buying off Ebay. Nowadays, a lot of company's have a ebay store and use them for ease and so people can find em. Just check their feedback and if they look legit, send them a email and Always check warranty.

 

[Epy]

high pressure, that's what I meant...

 

[JDMMA70]

But our oiling system isnt a high pressure low volume setup.

 

[Epy]

Shit I meant,

High volume.

Toga, ive heard is the best?

hahah. I wrote the wrong thing again the 2nd time... woops. drunk.
