2JZ-GE to 2JZ-GTE Conversion...?

[bugeyedcreepy]

Hey Guys,

Still toying with some ideas. Since I already have the complete GE engine, I'm looking to get some advice on converting it to a GTE. What drawbacks would there be in my obtaining Turbo VVTi Head and Manifolds and bolting the Turbo internals into the block? I'm already aware of the oiltap and return I'll need for the Turbo but what other "Gotcha's" if any do I need to be aware of?

I am looking at convenience... from a space point of view that is. Rather than buying yet another Aristo half-cut or similar to land in my already overcrowded front yard, I'm looking at getting the Turbo 2JZ top-end and finishing off this project I've started, Those who have already seen my place can attest to the Wrecker style look and feel I'm starting to foster. I'm also looking to utilise stuff I already have since I'm not sure I would recover much in selling the 2JZ engine anyway...

Should I pursue this or am I just dreaming...

Oh Yeah, another thing while I'm at it... What's the standard redline/cutout of these engines and how far can they be pushed past that before a major bottom-end reshuffle needs to happen??

There is probably alot less hassle involved in just dropping a stock gte in its place, if i know from anything you should do things right the first time comming from spending all my money on the gze, then low budget gte, then doing it properly the last time around. Not to sure on the strengths of the block, i would hazard a guess they are the same, if they arent i would definately think alot more about getting that yard messing halfcut!

i reakon it would be way easier just to get a 2jz engine and change over the whole thing at once.

doing it the other way means pulling apart two engines and having more leftovers. just take the NA engine out and drop turbo power in......a lot less hassles than the way you stated.

I have heard of putting turbo manifold on atmo engines, dont know of the exact similarities on the internals, but i gather that it can be done. But again, for the hassle factor, just get a long motor and fit it up.

Thanks Guys...

The next logical question will be finding the best way to get a complete 2JZ-GTE without having to get the complimentary half a car surrounding it or having to pay as much if not more without it...? I've loitered around this forum to know they're awful rare to find and even the importers don't get these engines in unless you're willing to pay twice as much up front... Are there any Toyota specific circles (i.e. Clubs or Websites) where this type of engine would be a little more prevalent...?

I also remember seeing a list of half-cut resellers/importers here too, do any of them in anybody's experience ever sell just an engine??

The GE engines dont have the little oil squirters under the pistons other than that i think thay are the same as the turbo ones all over

cheep optoin get a 1jz head and manifolds and drop it on!! ... 1.5JZ proven to go very well

i have a couple of 1j heads and manifolds if you are thinking of this option and ill do a direct swap for the atmo stuff so parts wont cost you a cent all you will need is a head gasket etc

let me know

hmmm, I'm interested...

You'll have to give me your number so we can talk shop. I'd still be up for turbo pistons, etc. but it'd be a workable solution. I'll still be running a full 2JZ for this little warp machine but ideas are already brewing for a 1.5JZ Application.

I recon for lowish boost you could just drop the head on and go, could always use a thicker head gasket to lower the comp a bit to be on the safe side. should be good for about 250rwkw safely with the GE pistons

anyway PM sent re heads

This topic has been covered extensively at Supra websites, check out www.supraforums.com.au and www.supraforums.com and search for NA-T. The oil squirters are some of the bigger gotchas, also compression and exhaust manifolds are also issues. Have seen members of the NSW Supra club(JP) pull 318RWKW from a 2JZ-GE with NA-T conversion. It has some serious traction issues, and runs a little rich, but goes hard.

dude just turbo the 2jz...

If you are serious, buy some forged pistons for it (thats all that needs replacing really) rods are identical, as is crank etc...just run a large oil cooler up front to help with oil cooling. You can still buy any 2jz turbo kit which will bolt straight on etc etc. I also believe NA cams are better for creating power. Thousands of ppl have done what you are talking about. Its called the "NA-T" conversion.

The above is exactly what i am doing with my 7mge - 7mget project. which i expect to get big power from.

my 2c - as i thouroughly believe in making use of what you already own

Wrong. GTE manifolds don't bolt up to GE heads, so if you want to turbo a GE you're limited to the "NA-T" kits. The vast majority of turbo kits are designed for the GTE and won't work.

I'm sorry, i stand corrected. Unusual they are different to a 7m :s

Nevertheless - as aforementioned theres a fella with 318rwkw out of one, which i suspect is more than enough for this lad by the sounds of things
