i am looking to build a 600 rwhp mk3 but am not sure what to do...i want to do a 2jz swap but at the same time i am not sure if it would be cheaper to build a 7mgte motor?

if i build the 2jz i will run a single turbo instead of twin

Is this really a serious question? Dude, 2jz all the way. More power out of the box. 1000x more reliable. Cooler looking motor. Cleaner engine bay. And probably comparable in price when it comes to rebuilding the 7M and getting it into "reliable" condition.

All correct except for the last statement. What does a 2JZ engine, trans, ECU, harness cost? $2-3000?? I know from experience that you can build a "reliable" (like they dont exist :dunno: ) 7M for less than that, and still have money left over for mods.

We just finished a build in our shop, ran a total of roughly $4500-5000. The car ended up with a fully built motor, fuel system, upgraded CT, IC, hardpipes, full set of gauges, traction bars, etc, etc, etc. The car makes over 400HP and is reliable as hell. On the thread starters 8K budget, I think he could easily make his goal with the "unreliable" 7M.

can I make a suggestion? Don't go into this build with a horsepower goal in mind. Figure out what you want to do with the car and build it to be the best for that purpose.

You want to drag? Drift? Autocross? Show? 600 is just a number. What's your real goal with the car. $8k will get you far but that money may be better used elsewhere in the car depending on the purpose.

ok i know this is a STUPID question, but the 2jgte and the 7mgte? is the only differance the head? or are the bottom ends different too. Or dont the engine codes work like this for this car? i know some cars you can just swap the head, like the 3s-fe
to a 5s-fe but ANYWAY, try not to call me an idiot when awnser this question ty!

The engine codes do work like that.

However the 7mgte and the 2jzgte are not from the same series. The 7mgte is an M series engine and well the 2jzgte is a jz series engine. The heads are completely different. The bottom ends are also completely different.
as well the non turbo counterparts have different machine processes on the casting so they are also different in regards to oil and sensors.

Im just adding fuel to the fire cuz Im tired of these threads. lol
I just went over this in a thread in the 1JZ swap section on Friday.

Id deff like to see an A70 pull a boat though. Im sure it can be done. my dad pulled one with a freaking Reliant one time. hahahahaha. Almost got pulled back into the water though on the way out, but it made it a few times.

Go check out the rock crawler toyota based truckts that swap the 7m into them. That is tree stump pulling power there!

The only thing I am going to put in this thread, again..

Are you a lazy fucker? The 7m is NOT for you.
Enjoy cutting corners? The 7m is NOT for you.
Have no money? The 7m is NOT for you.
Just a plain ole idiot that thinks they know about cars but don't. The 7m is NOT for you.
Don't have an inkling of what maintanace is? The 7m is NOT for you.

You can't really compare a 7M and a 2JZ.

Neither will be cheap to 600hp. The 2JZ is, as it should be, a superior motor. I don't think it's really even a fair comparison....most 1980's turbo motors have a bit of reputation for their interesting characteristics...

Get a 2JZ if you want to impress the local ricers.

You could probably build a 7M for less money than a used 2JZ intall. And then you would have a motor that's stronger and newer. It cost me $5500 to build up my 7M from top to bottom with forged pistons and rods with new bearings, ported head with oversized valves, 264 cams with BC springs and retainers, new oil pump/new water pump/new timing belt.

Yeah, what figgie said... but im still a lazy mofo and still drive it like i stole it every other day... Just remember to check the oil levels and you'd be good.

i stayed 7M because of cost... and on top of that, i really wanted to experience a built 7M over the past bpu "unbuilt" 7Ms that i've owned.

Ultimately, if this one goes down anytime soon, i'll be going 2jz right away. I already got like a grand saved up just for that.... and i guess i can always sell my 240sx...

EDIT: Oh yeah, go with whatever you want man... your car, your engine, and your money... nothing else matters.

2JZ-GE-T. An NA 2J can be had for around $500. Rebuild it with TT internals, ARP hardware, ect.. for 2k. Add in a NA-T kit for 4k, AEM EMS for 2k and supporting fuel mods and IC, piping exhast. Talking 10k for a 700 horse setup that is as reliable as any turbo motor can be expected to be.

here is a 2jz recipe for 600 WHP.

Now you don't need to follow every step but must be similar
I'm guessing you want this on close to pump gas.

67MM turbo
Meth/water
AEM
3-4"exhaust
manifold
Intercooler 3-4"
pipes
dual fuel pumps
Fuel lines
clutch
W/B 02
Fix your 2jz coil packs form cracks or buy new ones (always cracked)
Fix your crusty coil pack connectors
PS line for the 2jz
Throttle cable for 2jz
Bell housing
rear sump pan/pick up
O ring for the PS pump (which always leaks)
Valve cover gaskets, cam seals, front main, rear main, timing belt
misc here and there

= big hole in your pocket.

Ask me how I know

Honestly if you are 18-21 and don't have a full time job don't even think about it.

stick with upgraded CT26, and maximize what it can make.

Save your money and just do like ZaZZn said! I love having a MK3 with a 2j and alot of power, but at the end of the day you think wow the amount of money I've put into it, I could have..... Always those thoughts. And really, when will you be happy? At what hp range? I was at 631 and now going for 900 and then what?
It sucks.......

O, and I forgot to mention, I was going for 800 before this posting and now I'm saying 900hp.

8g's?

2jz?


since we are being silly....


why not a Xuz engine instead? lighter than the 2jz boat anchor, more power and definetly a higher power potential ceiling! And since Toyota put those in the new cars, MUST be better than the 2jz!!!
