Had this idea of swapping a turboII engine/tranny into my 82gsl. this would be quite a bit cheaper then doing a 20b swap, and probably alot less difficult. i was wondering if i would have to do anything like motor mounts or what not?

I had this other idea. would it be possible to take a turbo from a TurboII and put it in an Fb along with the intercooler and such? would it fit right, and would it work?

search!

I would say to search too, but it's rather difficult to determine what to search for.

I'm usually easy on the newbs on searching etc but this topic has been beat to to death. Search the 1st gen forums bud.

holy crap...those websites have a shiat ton of information. thanks a bunch man.

i was looking throug those webpages you gave me, and all of that is for the gsl-se. are the motor mounts for the 13b in that the same as the motor mounts for the 12a?

82tougemonster

ok...so i did some research. What i found is somewhat disturbing. Another forum says that the 12a and 13b mounts are 20mm apart...2cm. 2cm that will cause the most frustration of my life?? is this right?

The 13B engine is 20MM longer than a 12A.The front mount bar from any 1st gen can be used on a TII engine,youll just have to notch the holes is its from a 12A.

To mount the TII engine,youll need.....
GSL-SE oilpan.
GSL-SE front cover.
Modify the stock rear mount to fit the TII tranny,and shorten the TII shifter position by one inch.This requires opening the back of the tranny,but isnt too hard.
All of this is quite easy,only requires a bit of mechanical creativity and will get you installed and mounted securely.

The fuel system will require a high pressure EFI pump(either external or intank)
The exhaust will have to be replaced so it mates to the turbo and can flow adequately to make power.
The cooling system should be maximized since youll be doubling the HP.A stock size 79-82 radiator with 3 rows,will do well along with the stock 82 oil cooler.
The wiring can be tricky.75% of it is plug and play on the TII.But the drivers side harness must be made from scratch.Its about 15-20 wires and controls the ECU power,CAS,coils and fuel pump relay/resistor.
If smog isnt an issue,spend a little more and get a standalone ECU.Itll require tuning,but will eliminate a lot of wiring mess and is far more capable than the stock ECU.

2 pieces of advice.....
1st....For simplicity,its best to stick with the S4 TII engine(87-88).They are more common,the OMP is mechanical like the 1st gens,and it still makes 185HP stock.
The S5 (89-91)is more power(200) but costs more,is harder to find,and will require a custom made front cover to accept the electronic OMP.

2nd....avoid the S4 turbo and manifold.It has a terrible design and small wastegate.The S5 turbo and manifold flows much better and has twice the wastegate volume.Itll bolt right up to a S4 engine,is easy to find,but will require a boost controller to make more than 5-6psi.

So the series 5 turbo and mani will fit just fine in an fb? I have both a series 4 turbo/man and series 5 turbo/man and was trying to figure out which one to send to bnr to get highflowed.

thanks

ok....let me get this straight. The s4Trubo II engine/tranny will fit right in the first gen by modiflying the holes on the front engine mounts, and modify the rear mount?

How much does a stand alone ECU usually run....?

and the S5 turbo manifold and what not will fit right on the s4? so how much more HP would that get?

steve84GS TII

If you use a 12A front crossbar,youll have to slot the holes,but it will work.The rear crossmember has to be dropped one inch with spacers and the rubber mount's holes redrilled to match the holes in the tranny.But the stock member and rubber mount can be used,no fancy fabrication.

If you use a boost controller to get the pressure back up to stock levels(8psi),you should be around 200hp and 200 torque.The S5 engine has a factory boost controller run by the computor to hit 8spi.On a S4 engine,the turbo wont be able to make more than 5-6 psi mechanically,which is about 170hp.With a boost controller,you can take the turbo to its max,about 10-11 psi.Just be sure to adress other systems before doing so(fuel pump,injectors,intercooling,clutch,driveline,cooli ng)

The S5 turbo is very close to the stock idler arm,but it fits with enough room for a small heat sheild.Its works so much better than the S4,its just not worth working on a S4 turbo.The S4 requires a big actuator for the twin scroll(which doesnt clear the FB X-member),it starts creeping very quickly because of its small wastegate,and the manifolds are prone to cracking.

I run a S5 turbo with a TO4B compressor.On a streetported S5 engine,it pushes 14psi all day long and doesnt even sound like its trying.The lag is a little more pronounced than stock,but its acceptable.Im sure the hot side is maxed,but Im happy with the power(about 300),so Im not gonna push it any harder.

$1,000 to $10,000 USD for the more common EMS models used on RX-7's.

Unfortunately, you just missed the Wolf group buy, so I think the Microtech LT-8S is now your best bet for a low budget.

Always make sure that your local RX-7 tuning shop can tune whatever EMS you buy. You are asking for trouble if you get an EMS with no local support, unless you are an accomplished tuner, in which case you wouldn't be asking such questions.

82tougemonster

Yes. it is quite obvious that im not an accomplished tuner. I dont even know if there is an Rx7 tuning shop where i live. if there is, i havent heard of/ seen it. i plan on moving to just north of seattle in the fall, so there will be one there most likely. So between 1 and ten grand you say. I also dont plan on doing the swap until i move out there, where i will be makin between 8 and 9 hundred dollars a week, so i will have good funding. yeah. im just getting all the info im going to need. i appretiate all of the help guys.
