best built motor? opinions? help?

[93 toyota]

hey guys, im a truck guy here in the toyota world but id like to start building up a turbo motor for a 2wd truck. i want this thing to be nuts. id love to spool around 300-400 hp but still be a reliable motor at the same time. now i don't know much about the toyota motors but i did just rebuild a vr6 (vw) motor for my passat and id like to bring that knowledge into my toyota world. so what id like to know is what motor i should go for and where to look. i hear a lot about the 2jz and the 7mgt but what do they entail and pros and cons. any information would be great !

2jz-gte from a north american spec supra already produces roughly 330 from the factory, and with a little boost control would put you easily into the mid-upper 300's on completely stock components. Not much more reliable than that.

A stock rebuild on a 7M-gte with a metal gasket will also do that power all day, every day, but would require a larger turbo to get up to the power you want with factory power being a, by today's standards, lowly 230hp. Fuel system upgrades would also be needed from injectors back, but going in a truck, you won't be using stock anyhow.

The 1jz-gte is another candidate starting at about 270hp, but new turbo/turbos are also required, as will fuel upgrades.

The 1g-gte is the only other supra based candidate. A really small 2L engine producing a mere 200hp factory and limited aftermarket support in north america makes this a bit of a stretch, but if you do fab work and don't mind a high reving/low torque option, this could still fit the bill, particularly if the engine bay is a little tight as this is the most compact engine of all the above inline 6's as well.

i really like the 2jz-gte

but what am i looking for used prices? ive done some extensive head work on my vr so the head work isnt a big dealt to me. block work is kinda iffy to me, id like to kinda stay away from this.

any supra enthusiets sites larger than on here?

The 2j is the most expensive option. A complete used longblock will run you anywhere from 1500 to 3000, and that may include an auto trans, ecu and harness, but you have to be careful to get the north american spec, or you can add fuel mods and other upgrades to keep to the 330hp number. If you want the getrag 6spd, add upwards of 4000 to that price.

I personally wouldn't install an engine I had not seen run, so add machinist time to this to at least inspect it, and while the blocks are about as stout as you can get, you can still get a lemon where you are dealing with up to 15 years of driving behind them. The 2j will need no head work if it is in good shape other than perhaps a skim before setting a new gasket if a machinist tears it down for inspection. It already has far more flow than you need for your goals, and I'm not sure that you will gain anything other than to say you can start shooting for 600+hp if you want to.

Supraforums is the largest community of MKIV supra owners and will have the most 2j information. There are a lot of wannabe's who will tell you they know their stuff too, so lots of reading is in order. They may have improved over time, but the mod team were a bit over the top and liked to play favourites with their friends and business partners, which turned a lot of people off. I don't spend much time there at all anymore. Supramania has the most MKIII owners, hence the most 1jz and 7m information, and has some limited 1g talk. Generally good people too, but with any large group there are some bad apples. We here are a farily small group, but I like to think of it as an alternative to the big crowds.

http://www.supracharged.com/ is a good site for putting a 7M or 2JZ into a shortbed pickup. http://www.supraforums.com is also good for general info on these motors. I would recommend you do alot of reading on these 2 sites. I've been wanting to do a 2JZ pickup for a while but just don't have the funds or space for another project. It all really depends on your financial ability. The 2JZ would be the best bang for the buck and give you the most potential. Making over 600hp without opening the motor is simple. Ebay is probably your best place to look for a motor. It will more than likely be a JDM motor with smaller injectors and ceramic turbos instead of the US 550cc injectors and better turbos. The other option is to get a non-turbo GE motor and turbo that. NA motors go for about $300 and an Ebay turbo kit will run you another $1000 but making big power is a little more challenging due to some restrictions like compression, a distributor compared to coil on plug ignition, injector size, etc.

There's no replacement for displacement. Why not go V8: 1UZ-FE, 2UZ-FE, or 3UZ-FE?

Come on we all know that forced induction is the great equalizer.
Plus the aftermarket for the 7M and 2JZ is much better.

Also the OP's desire to only reach to at the top 350-400hp...a stock 2j and a minor boost controller is the easy choice. Everything else requires significant additional investment.
