13b-rew motor in 2nd gen
Does anybody have any experience putting a 3rd gen motor in a 2nd gen?? I tried searching but couldn't come up with anything. Seams like somebody said a while back that it is quite a task, but i figure i would ask anyways. Anybody have a link to a teck article about this??? Thanks...

You'll need to construct a crossmember and mount positions to mount the stock FD engine mounts.  The downside is the stock 13B-REW engine mounts are bank if you need to replace them.
The other option is to redrill the center housing and use the FC oil pan and use both FC engine mounts on the 13B-REW engine.  The one big prolblem is that the FC oil pan is slightly longer than the 13B-REW and you need to seal the front edge to the front oil cover.  There are members who have gone this route still in here?
To me, there is no real reason to do this unless you want to show off the car.  The original 13BT is good for 500bhp and is more than enough for most people.  If you're going to go through all this trouble to stuff another engine into the chassis, you might as well go 20B...

There is a garage down here in naples that does 13b rew conversions all of the time. They do have to drill stuff to remount things, and they do modify the oil pickup, but it is much cheaper than doing a 20b. If you bring them a second gen, they will do everything, including a single turbo and entire turbo 2 drivetrain for about $7k, all ready to go.

Wow, now Im taking a guess that is if you bring the 2nd gen AND the engine right?Still, much less than a 20B, and I guess it could bring you more bragging rights.

I don't see what the big fuss is about running a 13B-REW.  If I were going to waste time on a swap, I'd go 20B.
The 13B-REW does have a little better intake port design and stronger pieces, but not many people can hit 500hp on such motors anyways.
Most of these questions are pipe dreams...

Yeah, you need to take care of the problem with the stock 13B-REW flywheel, as the stock pull-type clutch on the FD is a royal PITA to mate with the stock FC push-type.  If you can find a Kouki FC stock flywheel, that'll work, or else go FD/Kouki FC counterweight with aftermarket lightened flywheel.

So what your basically saying is it can be done, but its not worth the money unless your gonna go for like 500+ hp. That pretty much answers my question. Still, does anybody have a tech article on this swap? I'm just interested to see something about it. Thanks for the info guys...

-FD-in-FC- You say it took you around 12 days to complete the swap, but how much did it cost you. I know of a place where i can get a 3rd gen engine/engines for cheap... but how much on top of that would i need. and was the swap difficult. also, what about trans, are you useing a 3rd gen trans? or i imagin a 2nd gen trans would bolt up? questions, questions....

and i am with Full Speed Performance in Santa Cruz
the pics will be posted on Full Speeds web site soon

One more thing
I used a full JDM front clip
Full Speed works with a guy to get them over here
I can't tell you all my costs but I spent about $1000
over the cost of the clip on misc oil lines brake lines
a custom drive shaft since i used the 5sp from the clip
and other stuff wiring and what not
I got the car for $225 so this project didn't break the bank
I would never attempt this swap without a clip
i used everything
there was a ton of wiring to make this happen
lots of relocation of sensors and clips to make the headlight turn signals gauges ect.. work
personaly i didn't think it was that bad
but i have built cars from the groud up so its probably not for everyone

20B is about $10K DIY (without tuning)
Frontclip $2700
Intake/intercooler/radiator/exhaust $2500
Standalone $1100
Mounts $250
Turbo/Manifold/Wastegate/Bov $2500
Injectors/Fuelpump/FPR $800
Misc parts/Tune Up $150
Thats just to get it running in the car.
Now you have to get it to work with the tranny
So you'll probably want a new clutch/flywheel/counterweight $800
You'll also have to buy a modified oil pan or modify your sway bar to get the engine to sit in the bay properly.
Or...you could buy the front clip, and put everything from that into your fc with mounts and a modified oil pan
and swap in the 4speed AT, with a custom driveshaft. This has been done before, and I've thought of doing it to my daily driver since it is an AT.
