GTE Pistons in a GE?

Alright so I'm planning on doing a refresh on my GE this summer, And I was looking and doing GTE Pistons + Rods, and was wondering is there anything more to it? I read about head gaskets, etc and compression ratios. I'm not planning to got N/A-T anytime soon due to it's a clean car. I just want to build the engine to be reliable. *I did do a search and didn't find anything relating to my question with an answer*

few questions I have would help me to help you

are you ever going to boost?

are you doing the work yourself or have a friend that will do it for cheap? or is money not an option?

I don't /plan/ on boosting the motor as of now, Thought it's a 50/50 chance I will end up doing it. And I am very mechanically inclined so I would be doing all the work myself, I've been tearing apart race engines for dirt cars for 4 years helping a buddy of mine out with his shop.

gte rods, your ge pistons with new rings and a new ge head gasket

gte rods are an upgrade from your ge rods, gte pistons and gte head gasket will lower your compression so for your na application youll want to keep it at the factory 10:1

and if you are doing the work yourself you can always change gasket or pistons later for boost, personally if you are not going for really high hp id keep it with just the gte rods and run high compression boost, but that's just what I like lol

Do you know if there's any difference in bearings between the GTE and GE rods? I'm un-decided if I'm gonna use OEM GTE rods or aftermarket rods as well, Basically I'm gonna be doing a in-dept refresh. I've already got a full Aisin timing kit.

don't believe there is a difference? but if you going to change rods you will buy new gte bearings anyway, unless you mean will they fit on ge crank then the answer is yes as the crank is the same for ge and gte motors, you could go aftermarket but realistically if you are not putting power to it then there is no reason to upgrade your rods, the 170hp or whatever it is wont bend the ge rods, you may as well just change rings, bearings and gaskets. save your money on rods if you not going boost, put it towards other refresher parts, on that note if you can find oem gte rods for cheap then go with that, they are more then sufficient for na applications, cheaper then aftermarket and I feel oem reliability is where its at

What's the driver for the refresh? burning oil, low compression etc? Lowering compression on an NA motor is going to make it slower than it is now. I wouldn't do that until the turbo was ready to bolt on.

hence the reason it was my suggestion to only use gte rods and keep his ge pistons and use the oem ge head gasket, to maintain his compression. I go on further and suggest to even keep his stock rods since bending them on the stock horsepower is not in the foreseeable circumstantial future provided proper preventative maintenance is kept up

It has 306K on the motor, She's well due for it without a doubt. Plus I'd rather have the assurance of it having fresh bearings, rings, oil pump, complete gaskets done, pilot bearing, front and rear main, etc.

Why are GTE rods being recommended for an NA engine? The spindly little GE rods are plenty adequate to handle the GE - and are much lighter than GTE rods, which is an advantage.

if you read through all the questions and comments you will find the answer to your question, you will also find that in this series of posts it is suggested to keep his ge rods if he does want to keep it NA for a while.

do you have any further questions???

...It gives the impression you are recommending "upgraded" gte rods to this guy, whom we both can agree, would see no benefit from same.

Again I say read the post... that was giving with the intention of potentially going boost in the future, it is not rocket science. Also his original post says he wants to put gte rods to begin with... I unlike people like you who just think they know everything and there is only one way to do things I read, analyze and give an answer to his question. I will then go on to give other opinions. Unlike people like you who think they know everything and there is only one way to skin a cat.

How would you have answered his questions by simply saying keep your motor the say it is if you not going boost... he now has a bunch of scenarios and options to choose from.

Not only that I'm pretty sure hes not going to enter big dollar races where the weight of his rods are going to be so much of an advantage, stronger rods are more durable, regardless of weight. So why so much hostility? Perhaps you should go bother another post

And this is the reason I avoided forums for so long. Perhaps it is time for an early retirement.
