I has been a while since I got back on my supra swap.
A recap:
after getting tired of replacing headgaskets and blowing up the 3.0 V6 I opted for something with more horsepower and, if possibel, better fuel economy.
I don't know about the last, but now know that the first was a succes.

I put in a 7M-GE and mated it with a hybrid bellhouse to my stock V6 gearbox (R150F). The gearbox is mounted backwards, 4 inches to the rear. I also needed to make a new crossmember and shorten the rear driveshaft. I cannot extend the front driveshaft until I have fixed some problems I encountered with the supra engine versus the SAS. Since I use coils and a high pinion diff, things are quit different. The diff flange will hit the bellhousing when the suspension is fully compresed. I'll have to solve this later.

I also replaced the radiator, mounted an electric two speed pusher fan and built a new exhaust.
The electrics took me a week to figure out, since the previuos owner cut my wiring and rewired it. Wrongly of course.
Hooking up the engine turned out to be very easy. There are only like 10-12 wires that need to beconnected and everything works, from tach to oil pressure.
After making some non-insured test runs, I must say that 204 hp is way different from the stock 150 hp + headers.

Awesome!! you gotta post some more pics of your swap. I'm sure you get way better fuel economy than I do!!

Thats great! We need more pics of the install, I really like that grill

Can you tell us the final overall cost?

the most important question is, how doable is this swap for an otherwise stock 2nd gen? does the stock auto tranny take that much power?

if i recall correctly, there is a guy on 4x4wire who will take your truck, and swap in a 7m for $2500, including the engine. if you want an intercooler and that stuff it will cost more.

sounds like a great deal for a 250hp+ engine in a 'yota

hmm, i wonder if he can switch a TT supra engine into a 3rd gen...

I estimate that the swap, including 1 supra wreck, cost me about 1500-2000 USD.
A lot of things I replaced, like the bumper, grille, roof racks, radiator etc. were not really necessary. I just bought a entire stock from a toyo dealer who moved somewhere elso, so most parts I got for free.

Now I'm finished and have an overview of all things that needed to be done, I must say that it was quit easy. Fabricating the bellhousing was the most difficult and the electrics the easiest.
If you can get all necessary parts before you start, the swap can be done in only 3-4 days.

what year supra is that engine off? how many miles does it have?

4runner4ever

It's a '86 7M-GE with 100.000 miles on it. I bought the wreck without seeing it or knowing what type of engine it had. Wish it was a turbo.
But anyhow, this was an experiment. Now I now it works I will drive it for some time and see what breaks. And in the meanwhile I can save some money for a low milage 7M-GTE, or maybe an overhauled one.
It now has 204 hp but I want it up to 300-350 hp within a year.
That shouldn't be too much of a problem with a 7M-GTE.

Ok! this swap is very interesting. The Supra engines have been proven very reliable over the years, as long as good maintenance was performed. Power output can be tampered with too.

So, what years of supra motors will bolt in the easiest, what tranny options do we have, and what kind of milage are we talking about? Is the power worth it?

That's great, I'll be picking up my 7MGTE in a couple of weeks. I won't be doing the swap right away but at least I'll have the motor. My conversion will be a little bit easier, I'm told. With my '86 Runner all I need to bolt up is the bell housing and motor mounts from a non-turbo.This allows the GTE to bolt right up to my tranny and frame rails. Since I'm still IFS I'll have to find a rear sump pan and p/u until I sas. Lets see some more pics of the swap. I need some more ideas.
Your swap looks great, you're stoked mr. hp.

I did not use the option of the bolt-on W gearbox from a pickup. Those are quit flimsy.
I opted to use the R150F from my 3.0 V6 runner. So I had to make a new bellhousings since the bellhouse of a non-turbo will only fit a W series and a turbo bellhouse is too long. It uses a pusher type of clutch, instead of a puller type as found on runners and pickups.
In fact, you can bolt on all R type gearboxes if you make this bellhousing.
All W series will fit also with a nonturbo bellhouse.

Can this swap be done with the stock IFS? It will be some time before I tackle the SAS.

You said you have $1500-2000 US into the swap? What else did you need besides the engine, ECU and wiring harness? I have an auto tranny - do you have any idea what issues I might encounter? I had heard that the auto tranny in the 2nd Gen Runner was pretty stout.

I found a 7M-GTE out of an 88 for $1000 including the harness and ECU. I think it has 80K on it. Is this a good deal?

I've heard of people having to remove their radiator crossbrace. It looks like yours was retained. Did you mess with the firewall for clearance, or did the switch to electric fans give you enough space?

In case you aren't sick of hearing it: More pics of your swap would be very helpful.
