ok, i read up on the archives and found tha the s/4 tII swap into an 84-gsl-se i a piece of cake...am i mistaken. it sound like the only things i need which i have is my gsl-se oil pan and front cover....other than that everything will fall into place as if it where to go there to begin with. but i did keep reading about how i would have to re wire the ecu and what not.....what if i dont want to run stock anything and am shooting for some type of fire spitting animal of an engine. can i just mount the block and piece together from there to include stand alone, fuel/ignition components, turbo kit ect ect. and of course i would port the engine with 3mm apex seals...if i am sadly mistaken or sound realy stupidly confident please inform me about the info i need.

I thin there is allot of other things that must be done to fit it. (new tranny monuts, larger opening for shifter, etc...)

Latin270

but for the most part you are right about the front cover and oil pan. Also an after market ECU and if you can match up a 1st gen tranny your set. I dont know if it will bolt up or not but I'm sure someone will post an answer.

Ya, the 1st gen tranny will bolt right up. Don't expect it to last long though. The 1st gen tranny will take up to about 160lb ft of torque, beyond that and its going to break.

would there be any difference between swaping a 13bt-re from 13bt-rew onto a GSL-SE??
besides all the mounting and shifter issues??


thanks

If you go standalone,the TII swap is a breeze.
SE oilpan and front cover,bolt it in, and start wiring.
The GSL-SE is alread plumbed for EFI,so a good external fuel pump to feed the beast, is a simple install.

Doing an REW engine swap will be quite a bit more complex because of the crank fired front cover setup and 1st gen style mounting.If you ditch the crank trigger and switch to a CAS,you can mount it up easily.....of course,that also means losing the stock ECU and twins,at which point its not really an REW.

There are a few guys who have done custom REW installs,using the REW mounts and front cover/ECU/twins/ect.....but they require more fab work and there is less support here if you need info.Lots of guys have done the TII swap(myself included) and it is actually quite easy.For a S4 TII swap,there is almost no fab work required,and the wiring to get the stock ECU working is surprisingly simple once youve researched it and understand whats/what.

i plan on buying all after market fuel/ignition components anyway since i want a super powerful engine. what worrys me now is that i completely ripped apart my engine bay and now all thats in there is an engine, carb, headers, radiator,and igntion....i completely got rid of everything. no pumps, no compressers no nothing, i even cut out the wiring harness, just raw engine...since i did that will there be parts that i would need now. my car is in florida and they dont do inspections or smogg tests, so i plan on doing the same with the TII swap. ...just having exactly what i need in the engine bay. simple to the point power.

if these links work you should be able to see how plan my engine bay is.

steve84GS TII

If your goning to run a standalone ECU,the youll be laying out all new wires to the engine anyways.Everything in the engine bay can go,except for the obvious neccesary stuff like the brake and clutch master cylinders,radiator and plumbing.
The only wires youll need for the chassis is going to be headlights,turnsignals and the battery/fuses.All the rest is OK to be stripped out in preperation for the standalone.....

se oil pan match only with s4 or it can be used in s5 too?

z-beater

First of all me say that I did the REW swap and it was a fair amount of work but I would not say that it was too much more work than a T2 Swap. It really all depends on what type of modifications you want to do. Here are a few things that you need to worry about with a REW.

CAS... I used the SE front cover and pan so I was able to just use a 2nd gen CAS. If you make custom mounts then you can just use the magnetic pick-ups on the 3rd gen front cover.

tranny... the 3rd gen tranny shifter cannot be relocated however you can use the S5 t2 tranny and it should bolt up with no problems.

That is the main stuff. The prive will also be a little more...

Good luck,
Z

Like a SR20 in a S chassis.

steve84GS TII

The SE oilpan will fit a S4 or S5 engine.....but with either,you have to run the SE or a 12A front cover.The FC front cover, in addition to not having any engine mounting pads,has a different oilpan footprint than the 1st gen front covers.

Keegan

so you can use a 12a front cover

steve84GS TII

Yes,but the S4 4-line OMP will not bolt up to the 12A cover, like it will with the SE front cover.
And the SE cover has a boss under the OMP thats ready to be drilled and tapped for the turbo oil drain.

not to hijack, but what are you guys using as far as fittings go for the turbo oil return on your front covers? I'm in the middle of modding mine for the s5 omp, might as well take care of the oil return while I'm at it...

steve84GS TII

I just used a large tapered pipe tap to thread the hole,then installed a short piece of pipe....I think its about 3/4" O/D steel water or gas pipe....just regular hardware store stuff.
Then I cut the stock TII drain pipe short and connected the two with a piece of rubber hose and some clamps.
Pretty simple and cheap,no rocket science....

Heres a crappy photo I took before slapping the new S5 engine in,back in 02'.....

Ok that makes sense, just gotta make sure it in a spot that clears my elctric OMP...

z-beater

Since I had the REW it was easy. When I swapped the front covers I lost the front oil drain but I still retained the rear. I just routed my oil drain back to that.

I have also heard of drilling and welding in a fitting into the front cover. Just did not make any sense for my application. You could also use a barb fitting.

steve84GS TII

You cant go to the flat pad and still be able to clear the big electric OMP....there just isnt any room.
When I went to S5 controls,I had to get another SE front cover and move the oil drain forward.It now sits at the very front corner of the cover.I used the same pipe tape,a 90* pipe elbow and a similar piece of pipe to connect to the turbo.Its not at simple and straight as the S4 drain,but its worked fine for years.Still beats welding to the oilpan and having the drain below the oil level.You just have to be careful when threading the hole since its not nearly as thick up there.Thats the nice thing about using the SE front cover and a mech. OMP.....the oil drain boss that already there,is nice and thick.
Heres another bad pic.You cant really see it all,but the pipe and part of the elbow are visible just behind the front mount plate.....

ummmm ok , so i ran into a 91 tII, from what i know the earlier tII's are the easy ones to swap into my gsl-se but what about this series. what would i have to do..........i cant let this offer get by me, its $700 and its running....a complete fc running for $700 !!!!! i gotta take this..so what do i have to do to make this work !!!!...dont let the fact that the fc is is sooo cheap get in the way of explaining what i have to do to make it work....i know for that price the car can only be that good but i was going to open it and redo it all up again anyway..... all i want to know is what i have to do to make this thing drop into my 84 RX

20bdreams

keep in mind i have a gsl-se engine in my car as it sits , so what parts if any can i swap onto the 91 TII swap

steve84GS TII

Doing a S5 swap is nearly the same work as a S4.The wiring is similar,the control systems are similar,and mounting it up is the same......SE oilpan and front cover.

The main hurdle is getting the S5 OMP to work.Its electronic and cannot be unplugged if your going to run the stock ECU.But due to its size and bolt pattern,it wont just attach to the SE front cover like the S4 OMP will.

I choose to have my SE front cover modified to accept the large S5 OMP.That involved heli-arc welding to build up the OMP pad,then machining it down flat and redrilling the 3 holes.The S5 OMP bolts up like stock and the turbo oil drain is moved forward to clear it......both of these mods are visible in my last picture above.

20bdreams

you said "if im going to run the stock ecu" but i have no intention. im going complete stand alone (microtech ls-8)will tha thelp or will i still have to weld and stuff

82transam

iTrader: (18)

No, but you will either have to run an older style omp and rig up a linkage of some kind or just premix with 2 stroke oil. Otherwise its pretty similar to the S4 swap as steve said

steve84GS TII

Standalone EFI eliminates nearly all the hurdles when swapping ANY rotary.You wont have any problems,fabrication should be minor,if any.
The S5 will be easy as any other swap,since the stock EFI/control gear is pretty much what makes a S5,a S5......and your not gonna use it.
