What are the differences of the ge and gte internally? Im sorry if this has been asked already i couldnt find anything on it.
differences in 2jz-gte and 2jz-ge
- Thread starter Boosted516
- Start date
its really ez to find.. but the differences are,
thinner HG .3mm vs. turbo 1.3mm
higher compression pistons in ge
less oil squrters in ge
other than that there the same.

but there is still some oil squrters right? or none at all? i'm guess the rods and crank are the same.
rods are weaker. hence why a ge bottom end is only good for around 6-700whp. gtes have been good to 1000whp
Rods are the same and there are differences in the oil-feed/drain locations, oil pressure switch is different size (used a 16x1.5 plug to close the hole), oil pump does not have the deal for the crank angle sensor, and a few other minor differences.
I guess the question is, why do you ask? If you have a GE available for cheap, replace the pistons with GTE pistons (~$100 used) for the compression difference and use a standard TT headgasket.

Like stated above, the rods are the same, and the pistons are made of the same special cast material with very beefy ringlands.
The oil pressure switch hole size actually depends on the year, not GE vs GTE.
Crank angle sensor also depends on the year, not GE vs GTE (95+ GE's have a crank angle sensor).
^^Well there you go.
Get a 95+ N/A engine and go NA-T with it.... As an interim step. If it's not what you want, then at least you have things done most of the way.
When the time comes for choosing, you can throw a GTE head on there and go that route. Either way, the N/A has about the same power as a 7M Turbo.

What about valve springs and retainers? Cams?
Headgasket?
Im looking which MHG to order, can i order a 2jzgte one? No, right?

Shims are the same
cams are different
GTE= intake cam 1* off, have pickups for head mounted CPS. exhaust cam has no gear for distributor
GE cams= exhaust cam has gear for distributor; peaky & torquey.. ultimately very restrictive for boosted applications.
You can order a GTE HG, you could even use OEM GTE HG i you wanted to. Just choose your thickness wisely.
I have a local friend (Mike) who got a BHG on his NA-T. I would recommend swapping the pistons, to address the compression, instead of a thicker HG. A used set of GTE pistons runs about $100 and if ya need to later, you can easily find a standard/stock thickness HG.
I was showing Mike the piston's differences, when I was installing the GTE ones into the N/A block I am using. I have more of the GTE pistons, but am holding on to 'em, in case I can get another N/A block cheap.
I have not really explored the NA-T thing, but am puting the wife's N/A engine into my 1990. Gona sell that car tho.
I am sure that there's alot more info on http://forum.clubna-t.com/index.php, but have not done much research yet.

this is a good thread quick quesiotn siltl on topic lexus vs. toyota 2j lexus weaker really evyerone aorund here is telling me not to do a sc300 2j cus tis weaker i was under the impression thart it was just the vvti motors in i belive 98+ sc300s that were weaker am i correct
Not entirely sure what's weaker, but I think they may still be referring to the rods (that have been brought up a fewtimes).
The blocks are basically the same and so is the crank. If you replace the pistons/rods with GTE ones, then I do not see what else is left that may be weaker.
