My engine was overheated so badly the block surface was machined 12 thou before it was clean again. I also went .020 over pistons and it's working fine so far! 195,000 before the rebuild, too

If you do rebuild- replace all of the rubber coolant lines on the car- do not re-use a single one if the coolant had oil in it. That's just begging for a blowout, and Sean (funky_monkey58) will tell you how engines act without coolant...

I may have it rebuilt that would actually cost me less but i know its beat up bad i was getting oil and coolant in my intake hoses and through my brand new turbo! im not exactly 100% on what alls wrong with it.

so far im going to get a new radiator, i already have new gates radiator hoses, every coolant hard line or hose is going to be replaced if it hasnt already been by me, new coolant rez and sensor, new thermostat / temp sensor, cam gears belt and tensioner, either going to buy a new OEM oil pump and shim it and port it or throw in a mk4 oil pump, im considering a bigger oil pan from driftmotion ( i have done buisness with them a few times a verry good company by the way), fan clutch and shrouds will be replaced, new PS pump and maybe lines, rack and pinion will also most likely be replaced for other reasons... im sure theres more i just cant think of it off the top of my head. point is im going to do this one time and do it right the first time so i wont have any rreliability issues

Edit: also all the intake and most ventilation hoses have already been replaced weeks before it decided to turn into chubacca from starwars... sad to say but my supras nick name is now chewy hahaha

I have read and been told that it is an option for upgrading in the 7MGTE i havnt read up on it in awhile but i will post a link if i have time to search it.

get um IAN!!!!! talkin bout them chevys like that lol
what relevance does this have to this thread? or did i miss something?

ohh also since someone said something about chevys haha i may be putting a set of shevy big block valve springs in while rebuilding its suposed to ad about 500 rpm and increase HP slightly Once again not sure what all benefits are gained by this upgrade i havnt researched it in awhile i have moved living places 3 times in the past 6 months and i have lost a bit of data here and there so please forgive me for my lack of knowledge on these subjects.

He said he would put in an inter cooler, hard piping, BOV, lexus afm, 550cc injectors and the chevy big block springs for $1400 i spent 1300 on just the intercooler and piping at another performance shop and ended up having to get it refunded because of family matters and lost 500 bucks... deffinatly an FML moment

Ian was citing the fact you said you were going to install a MK4 *Oil Pump* into a 7M...this simply will never happen. Anyone who advised you to do this shouldn't be touching your car.
My guess is that he wants to install a MK4 **Fuel Pump** so you don't run out of fuel flow and you had a typo, hopefully.
Also, the valve springs will not boost your HP, but they are still a good upgrade if you are repairing a Head.

I would suggest looking over some of the vehicle build threads. Find a user with simiar goals to yous and start looking at what they are doing to get there. You'll find lots of different ways to do things and meet some really cool people along the way.

noone other than I will be touching my car other than the machine shop. ill see if i can find anything on the oil pump i know the fuel pump can be installed also. i believe there were pics of the oil pump but i may be mistaken.

thank you for refreshing me on the springs haha i have forgoten a lot in the past few months lol

will do this weekend for sure i need to research a few things before i get into the car again just to refresh myself i also need to get my camera out and working again to take pictures to post and also use as a reff for re-installation

No need to check on the oil pump fitment- I will tell you right now- the mk4 (2JZ-GTE or GE) oil pump assembly will not work on a 7M, ever. The 7M has a remotely located oil pump that is driven by seperate shaft so it can be in the middle of the block. The JZ series has the oil pump as a part of the front cover and the oil system is plumbed for it to work that way. They will not swap over.

I'm not trying to be a jerk, I'm trying to give you the correct information. There is too much misinformation floating around that it's hard to know what is good and bad info. :)

Buy an NA motor.There always in better condition than turbo motors and all you need to get is and oil line kit.

Okay, so you need a new harness and motor, right? Dude, go jz... NOW! It'll cost maybe just a little more upfront than starting over on the M, but the $ and headaches saved down the road will cover that tenfold. They're just better all the way around. Maybe ge-t since you have most of the stuff readily available already? There's really no logical option other than jz...

Dont listen to this idiot.

If you do the 7M right, you will do it once.
Its douchebags like this who think the JZ series are flawless and never has problems,
its obvious he knows nothing.

In my opinion pull and strip the block and take it to a machine shop, have them check everything.
Then go from there...

It will cost you much less to rebuild it than to buy another complete 7M.

Rebuild it, new everything. Seals, bearings, gaskets, etc etc.
Basicly like a brand new motor.

You buy another used 7M then you dont know how hard they beat on it, and how they did
things. You rebuild it then you will "know" its going to run right, you "know" its going to last.

Just thought id ask in this thread before i searched, what all is needed to use a 7mge and put on the GTE turbo and everything?
are there any benefits from doing this?
and also what are the benefits of putting the 7mge cams in a 7mgte?

thanks everyone for all the information it is greatly appreciated :)

That engine will not like you for long. The GE block has higher compression, so you would need to be running very high octane to keep away knock even at stock boost. Turbo engines are low-comp for a reason, and that reason is knock. That is, unless you're keen to get a stand-alone, big injectors, E-85, and really have fun! ;) Ask me how I know.......

As for the GE cams, people go both ways on it, but without adjustable cam gears I think you'll see a loss. With the cam gears you may be the same/very slight gain. Not worth it IMO.
