Hey guys, Ive had my mx83 cressida for about a year now, bought it with a BHG and fixed it drove it stock since then and blew the motor again just recently. Just bought a blown 7mgte that I will be rebuilding and swapping in soon. Using all my money for that right now so hopefully it will be sooner than later. Plans are to run the 7mgte NA with all the 7mge accesories to get it smogged then bolting on the 7mgte goods since I live in cali. I'll probably try to have the car reffed and stickered after that so i dont have to hassle with smog.

sweet. never heard of that before. does it just bolt in? Do you need custom mounts? Is it hard to wire? You should just keep it auto. Manual isnt worth it in LA traffic.

pics?

get a US 2jzgte and get that ref'd! or hell, a 1uz! screw anything 7m related.

Here's some pics, when I got her. just stock with my bike rack on it.


and me working on her. Bought with BHG fixed it half assed now im in the process of the 7mgte rebuild.


I would do the 2jzgte if i had the money, believe me. 7mgte is cheap bolt in power.

Finalized plans are 7mgte with ge pistons and t04e compressor wheel 57 trim or 54 trim upgraded ct26 turbo. looking to make a reliable 350rwhp with lower boost. GE pistons will keep the low end 3.0L grunt and quick turbo response.

7MGTEs are awesome unless you track it. Yeah ok, actually a M motor is never awesome. People ditch 7Ms for a reason. You WILL spend more keeping a 7M on the road than you will just buying a 1J or 2J and never looking back.

mine blew at 1000rpm at 5 mph

I know there are lots of 7m haters out there. Problem is I live in California so doing a smog legal swap is going to be important so 1jz is out the window there, 2jz would be my only option besides 7m and is at least twice the cost. So i decided id go with a completely rebuilt 7m, ARP head studs and MHG which will fix the notorious BHG problems, all OEM bearings to maintain tight tolerances and a new oil pump which should take care of the bottom end. Im not a 7m hater and have done my research for building a reliable powerplant. There has been more than a few 500+ whp 7m's so I dont see why I cant make my 350rwhp with the setup im planning. Sure id go the 2jz if I had the money and wanted the smoothest most reliable toyota engine ever produced, dont get me wrong it is a sweet engine just deciding against it is all. Maybe in the future. Thanks for all your concerns though. I appreciate it.

[leon.borden*]

Those are drag cars... they see probably 60 seconds of full throttle a year, the rest of the time is spent working on them. Reliable != 7m. Even a 2JZGE would be a better bet than a boosted 7M.

Actually a 2JZ is a much more reliable and cheaper option. K thx, bai

[timtiminy]

2jz isnt necessarily cheaper, when you think about all that goes into putting it in. Bellhousing and wiring alone add about $1k just to get your car moving with it. Sure the engine might come out cheaper but thats just the engine itself, does no good if its not running in the car. I know 7m's have a bad rep but honestly its an engine just like any other, only shortcomings are the head gasket and torque specs from the factory sucked, fix that and it should be just as reliable as any other toyota engine.

[mcfizzle]

.......... riiiiiiiiiiiiiiight.

[timtiminy]

trust me I would love a 2jz. Maybe in the future. For now its 7m for me.

[leon.borden*]

If you think that the headgasket issues are the only issue, you obviously know very little about 7Ms. 2JZs are a square 86x86, whereas 7ms are 83x91. A ported, polished 7m head with 1mm oversized valves still does not flow as well as a stock 2JZGTE head. Should we even start discussing how 7Ms oil pickups and oiling systems are a disaster waiting to happen? Headgasket woes are just a small part of the equation as to why 7Ms are garbage. Anybody in the world can put a 2JZGE into a Cressida for under 1200 dollars, have enough power to have fun with for the time being, and beat the living fuck out of it while enjoying your car. Those motors are everywhere for 500 bucks. But whatever, after you waste all that time on an inferior design, you could have one hell of a 2JZ.

[timtiminy]

Show me where i can get a 2jge with everything i would need to put it in my mx83 and be smog legal in California for under $1200 and Ill definitely consider that route over the 7m build. I just dont think that I can honestly find a setup for that amount. Biggest reason for going 7m is ease of swap and availability of parts, being able to smog it here in California, having a freshly built engine, and making moderate power (300-350) cheap. I already have a 7mge and 7mgte and with all the parts i have between both engines I wont need much more.
I would agree that the 2jz is a much better design, You really dont know how much I know about the 7m so for you to say that "i obviously know very little about 7m's" is really unnecessary. Sure the 7m is inferior to the 2jz, its a newer engine design. I am aware of the undersquare design of the 7m, Im not looking to be revving to 8k all day long, I think the lower end grunt will be a plus for everyday driving. 7m's oiling problems are largely due to running an old ass worn out oil pump with improperly sized bearings and the stock oil cooler setup which i plan to get rid of. I'm not going to just slap a 7m in as is and expect it to be good, I plan on taking care of all the ailments that plague the 7m and should have what I am looking for.

[leon.borden*]

Thats my point. Youre spending all this money to try to polish a turd... or as you say "take care of all the ailments". I just picked up a backup 2jzge two weeks ago with no tranny for 275 bucks. They are literally everywhere for dirt cheap. And thats in a shit town in Alabama where I cant find a taillight for a X7 in a junkyard. I dont know your smog laws in California, but I would think going to a newer engine that is MORE smog efficient would certainly be legal.

[timtiminy]

well to go to a different motor here in cali requires that the engine have all the emissions equipment from the original car that the motor came from and is smogged as that car not the car that the engine is in. its a long process and requires going to the bureau of automotive repair and a referee has to inspect it to make sure is it completely stock with everything functioning as it would be from the donor car, all intake and exhaust components must be factory original and from the donor car.
For whatever reason, I have yet to find a 2jz for that cheap here in CA, maybe its because they are in more demand here than in Alibama where most people are driving USA made cars.

Picknpull, bought a complete motor swap for 250 bux.
