Is it possible to fit the twin turbo engine rom an FD in a FB?

I found someone who can get me an engine from an fd with the full twin turbo setup etc.... I was wondering if it can be made to work in a fb body i havent seen one yet and would a 13b motormount hold it? I know im gonna have to get a new tranny etc to make it work but I wanted to know if anyone has done this i saw a thread about someone trying to twin turbo his 12a but that dosent seem like a very good thing to try. I havent purchased the engine yet I wanted to see if anyone has gone this route before.

I went for a ride in a fb with a fd motor in it and it was a rocket, the motor was all stock.
The guy had no clue on what he was doing, he wasnt a mechanic he just dicked around with it until it all worked.
He shortened the fd tranny to fit and ran the stock GSL rear end.
He said he had less than $3000 invested in the swap.

you can fit just about any v8 in our cars so I would have to say, yes it is very doable.

there's no way in hell he swapped a 13b RE or REW for $3000. I'm at least double that into my 12a Blow Through build and the car isn't even running yet. Hell there's $1000 alone between the fuel system, charge piping, and intercooler; all things that would be required when swapping any turbo engine into an FB. You could barely even by a good condition running FD motor for $3k, much less with a tranny. Plus the FD tranny won't fit in an FB without cutting and modifying the tranny tunnel. And to my knowledge there is no way to shorten the FD tranny since the shifter housings and tail shaft housings aren't interchangeable between the FB/FC and FD. Not to mention the FD tranny uses a pull type clutch that would require modification to be used in an FB. Soooo...... yeah... BS.

I think I'm gonna have to agree. On my turbo setup I havent changed the motor. I've swapped a turbo and fuel injection on my na block. I've spent $3k just on this. I did do everything RIGHT though and MYSELF to save money. I didn't want to skimp on anything. Not my style.

I will say when I planned everything out, I planned on spending 1,500.

I will let you know you ARE going to spend more on this project than you plan. Your going turbo. Not everything is going to be right the first time. Unless your God lol.

It has been done plenty times, most are single turbo though.

Just going off what buddy told me, he said he got the motor and tranny for 1800 bucks out of a salvage yard and everything else is ebay bought.
I saw the motor in there, i went for a ride, it was fast and felt dangerous so I had no reason not to trust what the guy said.

I believe it. If he scored a good deal on a complete REW block with the stock wiring and ECU, you could easily finish the swap for less than a grand if you try hard enough. A Walbro is only about $100, and a good exhaust can be done for less than $500 easily. Figure another $150 for an eBay intercooler and some couplers, and you still have $250 to spend on an air cleaner assembly, some pipe for the intercooler, and other miscellaneous expenses. It only gets expensive once you start wanting significantly more than stock power.

Anyway, yeah, it'll fit. I'm doing the same thing in my FB to replace my stupid blow-through setup (which I spent less than a grand on; I ended up pretty much exactly meeting my budget, miraculously). REW block with S4 TII rotating assembly, with the stock twins initially, and a MegaSquirt.

Yeah, he got a great deal. I bet it felt ridiculous. My buddies FD with stockport rebuilt motor with all new internals and non sequential turbos is very very quick.

True. I just pictured standalone and goodies haha.

Exhaust can be done for less than $200. Full 3". Atleast in vegas .

Yep. Mine ended up being more since I used a Racing Beat presilencer in addition to a Magnaflow. Which is a fantastic combination, by the way.

well i wont tell you the price im getting on the engine lets just say its a steal it will be going into an 83 gs that im stripping down mostly for track use anyhow. This is for the engine turbos waterpump intercoolers etc from an fd with about 40k before a rearend collision basically the engine bay of the fd going into an fb i may be able to snag a tranny from an fd off another guy that put an LS1 into his I was just wondering if it can be done and done correctly id rather this go into a fun toy than a sandrail (my other considered option)

Wouldn't it be easier to use a TII tranny?

if a turboII tranny will mate properly then yes it would be easier since the block is essentially the same correct?

It would be easier to use the TII trans. Fitting a REW with the twins will work, but seeing as how I passed 255hp a long time ago, I wouldn't bother with the stock twins. But that's just me.

I almost bought a T2 with tranny and an ECU for 400 smackers, it needed a rebuild but i was fine with that, then some other guy beat me to the place and bought it. Man i was pissed that day. For some reason Rotaries are fairly inexpensive here in GA

I just got an S5 T2 engine for $250. It has cut wiring and no ecu though. It's an all stock jap motor, except for the hks blow off valve. Even if it needs a rebuild, I think it's still pretty good. I'll start working on it once I'm finally done my gslse rearend swap.
