using GE block to build GTE

[mk3ftMFw]

I have my blown 7mgte, and everyone knows 7mge's are much cheaper....


My 7mgte has a rod knock, if i were to buy a 7mge could i use most of the stuff from my 7mgte to build a new 7mgte??


Help me make a list:

1.) I know the pistons are different, so can i swap the GTE pistons into the GE??
2.) Ill use my auto tranny from the GTE.
3.) I'll use the N/A cams, i hear they are better.
4.) I plan on doing a MHG.


Give me your .02..

Youll need to either tap the block to fit the GTE's two knock sensors or wire the two knock sensors together.

If you are going to build a new motor out of a 7mge block why dont u just build a new motor out of the gte block?
That way you wont need to fuck around or drill this or tap that...

Your GTE block may also have oil squirters which the GE block will not have.

I agree with TTE, just rebuild the GTE block if you can.

or buy mine cheaper than a stock rebuild will cost you. I posted a link in your wtb thread

o thanks ill check it out...


The rebuild will cost almost as much s buying a "jdm low mileage" motor. The crank may need to be machined, the block and head have to be machined for the MHG and arp studs. god, im stressed..

Yea you build it and you know what you got or you go buy a JDM and it blows up in a week then your out of luck.

if you have a ge block on hand then i say go for it but if your going to run higher levels of boost lets say over 10 then you should invest in a set of forged pistons to compensate for the lack of oil squirters.

First of all there's probably next to no point in buying a JDM motor because half of them are trash right off the bat anyway. Secondly, unless you rod knocked your current GTE really badly (drove it around for a long time with RK), why dont you look into rebuilding it...a jdm would have to be torn down anyway? I wouldn't recommend using a GE block, you could get away with it but its kind of a half ass way to do it. Btw im in Ohio too, who's pulling/installing the motor for you...i need some help in that department in the coming months.

i pulled a ge from my local junkyard, 75 dollars, took the crank and rods and used them in my gte block. i used the ge bearings too.

note: i did measure every single part that went with the crank and they were all within specs. almost 5k miles later and lost of abuse and everythings fine.

what do i personally suggest for rodknock? buy a crank kit from autozone and a set of rods that have never seen rodknock. $500 or so.

Are the oil squirters really THAT important? I was going to pull my 7mge and do a turbo rebuild on it as well, and I was under the impression that if you did everything (drilled and tapped knock sensors, all gte electronics, all that jazz) and the only difference was oil squirters.. then you'd be just as fine as a 7mgte?

 

[starscream5000]

It wouldn't be too important if your goal was a stock engine, but if you're going for performance, you should keep those pistons cooled down with the oil squirters.

 

[Burntz]

What if you're only looking for 400 ish HP? lol

Also the ge block does not have the opening in the block for the turbo oil drain..Someone correct me if Im wrong on that.

for reference turbo a blocks did not have squirters

and you oil feed will be teed in where the oil pressure sender is and you will have to drill and weld in a bung for the turbo drain. you dont have to run water to the ct26 if you dont want to. the only concern would be higher compression ratio but if you run a little thicker head gasket and watch your a/fs youll be ok with a na block i dont see what the big fuss is about

 

[mk3ftMFw]

Can you just buy a new crank, and rods????????

1.) can i attach my current pistons?
2.) With a new crank, a new rods from pepboys Will everything install right?
3.) What will i have to worry about in the future??

id rebuild w/ the turbo rebuild kit, so compression woild be stock. their is more then a few spots to put the oil return right?

 

[mk3ftMFw]

the oil pan is easy to tap... i did it on the camry when it was running boost.


someone answer these... ill make love to you.

1.) Yes, the pistons and rods are the same same, except for size for compression, etc.
2.) If you know how to, yes, they will.
3.) Shit you mess up.. If you dont deck the block and head and get a metal head gasket, then you may have to worry about a head gasket. Its the only weak spot on the engine really (coming from the factory)

Oh, and I'll be fine without your lovin.. you can keep it lol

If you swap your gte pistons into the GE block, you will have to machine the ge block to match the GTE pistons. Even if it is just a hone. GTE and GE blocks use different piston to wall clearance. So to use the ge block, you are looking at a bore or hone to begine with, which means dissassembly of the whole block.

My opinion is that, in the long run, you will have less money and troubles to just rebuild the GTE block that you already have.
