1. yes it would want premium gas but your fuel economy would most likely increase enough to more than offset the increased price per tank.

2. The ECU from the NEW engine must always be used.

3. Yea theres some diesel conversions that have been done but i dislike the CLANK CLANK CLANK engine sound.

 

Most people freak out when they see my turbo diesel toyota engine. Mostly because most didnt even know toyota made a diesel. I think a diesel conversion kit would make some serious $$$ here in the US. Mainly because diesel mini trucks are not made available here. On my conversion there was a few wires to hook up...I think 5 in all. Alot electrically simpler than a gas conversion I guarantee. Anyone interested let me know. You can find the engines from: http://www.4x4parts.com.au. Probably looking at $2000 for the engine and maybe $1000 for the little things (way expensive guess). I did the complete conversion for $2500 and get 35-40 mpg.

 

ORS=Off Road Solutions

They are a shop west of Denver and have been working on a kit to put a 3.4 in 2nd gen trucks and runners with the feeling being the 3.4 is pretty widely available, bolts up to the Toy trannys without much drama and gives the option of supercharging or using regular gas with 185 hp.

 

after reading all four pages i have to go with that superrunner says, i mean he has done it, and it sounds like he has done a few. but i dont think there is enuf demand to try and come up with a kit so to speak. now most people that should be doing an engine swap should be looking for more tq and not hp. i mean tq is what gets it rolling and spinning those big tires. i think the diesel is the way to go, and for wheeling a gas turbo motor is not the way to go in my opnion.

 

i have to disagree, for offroading you are using low range gears anyway so the stock motor is fine for that. even if i do the turbo ill most likely put a boost controller on it so you can turn the turbos off when you go offroad. im looking for more high end power so i can have some power on the pavement. besides, even the non turbo one has way more torque than the stock engine.

btw, heres a neat little article i read that can scientifically explain the relationship between torque and horsepower

So I have a 1990 with the 2.4 4cylinder engine? Will there be to many mods to do this swap?

 

What tranny is behind that motor? w56?

my 85 came with a 22re, the motor mounts were cut off and new ones welded on right behind them. sometimes the firewall will need to be mashed in a little bit. but that wasn't the case here. there isn't much room inbetween the radiator and the pullies off the motor so you have to modify a puller fan to clear in there.. very easy.. VERY TIGHT but i haven't had a problem with it hitting so far..pusher fans are also a nice added option .. to cool incase of over heating. the supra motors run hot, namely the 6th cylinder.. i beleive because there isn't much material for the heat to transfer to .. so the cylinder gets hotter.. i plan to put some thermal blanketing on there, to try help the disapation of heat from that cylinder.

you need the ECU, Alternator,umm i think thats it from a junked car to mate with the japanese motors. 7mgtes can be had for under a grand EASY. you need a custom bellhousing if going with a different tranny than W56 or stock supra turbo trany.. need Naturally Aspirated bellhousing to mate the two together..

and you need a Solid Axel .. from what i understand.. although. an IFS with a 4 inch lift.. drop down bracket type.. may clear. i wanted to swap a supra into my 89 but found the 85 already done so i go tthat.
hope i answered some of your questions.. there is a lot of info on this subject at many BBSs.. . 4x4wire.com is one that is very informative

LOTS of writes-ups and lots of help.

i want in on superrunners buisiness.. maybe i'll start doing these in so cal.


"It's better to make torque at higher RPMs so you can take advantage of LOW LOW gearing" .... i stole that from somones signature.. but it makes sense.

the supra has more torque than HP, only thing is , it doesn't make it right away.. it makes it at like 4 grand. the biggest difference i notice between my v6 and I6 is that off the line with no gas the I6 wants to stall the V6 utilizes the minisquel torque that it has and goes without any gas..

other than that difference .. there is the little difference of 100HP and about 6 seconds

SuperRunner,

Man, I've driven by your house 4 times in the last 2 weeks. Wish I would've known you were down there, I would've stopped by to see some of your work in progress (if you were okay with that).

I'm definately down with an aternative source of power if the cost isn't too high. Since my truck is an '89 the 7M seems like the best choice for me, right? I just want to be able to pull 2000lbs with the a/c on up these Idaho mountain roads with out having to drop all the way to 2nd gear. That and the 286k on the odometer is a small hint that I need to start thinking about what to do when the motor dies.

 

Well, still working on some. Will be getting in another truck this weekend. After this, I am done for awhile. I am not going to do anymore. If it was a full-time job, then maybe, but I am getting burned out working practicaly 2 full time jobs.

 

I might be back down that direction the weekend of the 23rd. If it's cool with you I'd like to have a look/see at some of this motor swapping madness. If it's okay with you I'll drop you a line before I come down so as not to impose too much.

 

Hmm, might be up hiking Mt Nebo that weekend, but yeah, let me know.

 

That's cool, like I said I don't want to impose at all. I'll let you know what becomes of it. Thanks!

 

Hey Dave, just stoppin by to see how things are going with this. Although this motor might not be the best choice for my rig, it looks to a great option for others. lkm how things are going. check you laters

 

Just finished another 7MGTE conversion. Was a 7MGE, but #6 cylinder was bad. Tried to fix, but I had to hone it out too much. So, we dropped in a turbo motor last night.

Specs:

1988 Toyota 4runner - bone stock with IFS and functional 4wd.

Quite a trip to see a little old saggy rear 4runner be able to spank a camaro.

2 more to do this month.

 

I think I'm good for a while with the engine I have, but I like the idea of swapping it for something more powerful in the future.

How much would a project like this typically cost (I have no idea whatsoever)???

 

Yeah I would like to know how much you charge someone to do the swap superrunner? How much did you charge the guy with the 88 4runner? How reliable are these engines? I heard they have headgasket issues and you can only get 100-150 k miles tops. Thanks

 

now THATS entertainment

 

as far as i know.. you solve the headgasket problem by
a) tightening down the factory one over specs.. i think specs are like 15 lbs insanely low for a turbo

B) a much better solution.. get a METAL head gasket and torque it to 75 or so


sh0ouln't have a problem with the HG after that.. but #6 is your problem.. keeping that specific cylinder cool is the trick to getting 200k outta the motor.. that and a good sturdy oil releif spring

 

I did his for pretty cheap. I can't do them for that cheap anymore. I pretty much gave him a lot of my parts for free. Any more swaps, these parts I must buy.

For a turbo swap, plan on about $4,000 without intercooler.

There are two places that do these types of swaps, but they only do supra's and lexus's. The only thing custom would be the exaust and intercooler and wiring(only on some). They do use a motor that costs about $2,000 more. But they charge over $10,000 for thier conversion. So you can see, $4,000 is still a very very good deal. Over $2500 of that $4000 is parts.

 

The cylinder head bolts were only torqued to 58 ft lbs from the factory. Lab analysis of the head bolts says that those very bolts should have been torqued to 72 ft lbs. The 2JZ-GTE uses essentially identical headbolts and guess what they're torqued to? That's right....72 ft. lbs. The fix is to torque your existing headgasket to 72 ft lbs.

As for not lasting 100k, that is simply not true. Torque the headgasket and maintain it and it will last and support 500+ hp without internal mods.
