RX-4 shell on RX-7 base

[McPie]

good news, project not dead it\'s moving forward, slowly, but for sure forward

so all these days nothing but beer and cutting... few more days and shell will fit

so....


dismiss rx-7 front pannel, finaly


lloks like the place for perfect fit between two shells


well it is the position how rx-4 shell should get down


oh about good news some people offred me a 13B rev, and after 2 weeks I\'ll know
what will be ander rx-4 hood

maybe a rx-7 fd heart 13b TT 250-280HP, yeap baby can\'t sleep day and knight waiting for those 2 weeks

[jiipee62]

Any progress?

[McPie]

just a little, searching for one tool plasma cuter that will make progres faster.

[BlitzBoy]

cool glad its still going, will checking on this thread from time to time

[apex_lt]

plasma? wow thats interesting.
p.s. i got doors!!!

[McPie]

I stuck in case of not having right tools, but...
meanwhile I wasn\'t sleeping and made some purchases
 
here are 3D puzzle
2x 13B REW engines, that I have to put under rx4/rx7 bonnet
 

 
I\'ve serached forum and I\'m confused
could someone help to find 13b tt swap project in to FC
couse last year I saw one, but can\'t find.
 
Apex, nice to hear good news regarding door. I\'\'d like to visit you soon and take a seat in a real RX-4
 
after 2 weeks I\'ll take vacations for 2 weeks and then do some business

McPie looks like you have way to much :chat
ok assemble the engine and bolt in the car. at least one 929 should become rotorized.

[RobbieRX-7]

Bump. How\'s it going?

[McPie]

now it\'s cold and I\'m working with engine, searching for rotor bearings...
 



 
also searchinf for drawing of engine mounts from 13b rew to 13b
and searching for info how to swap 13b rew in to fc

[FONT=\'Times New Roman\']The allure of swapping to a newer engine with more power is attractive, especially with the FD3S utilizing twin, sequential turbos and producing 255hp stock (over 55hp more than an Kouki FC3S).  In reality, swapping a 13B-REW twin-turbo engine from an FD3S into an FC3S is not easy.  There are two known methods of addressing the engine mounting problem, and we well cover both options.

The most popular method is to adapt the stock 13B-REW engine mounts to the FC3S chassis.  Trying to adapt the stock 13B-REW engine mounts to the stock FC3S engine mount locations on the chassis is a difficult proposition, and it\'s not a recommended design.  The stock 13B-REW engine mounts are both located on the rear, side housing; the stock FC3S 13BT engine mounts are located on the center, intermediate housing.  This makes for a sharp angle to connect both "points".  When researching engine mounts in general, the weight load vector is universally in a vertical plane; the engine (above) loads the mounts (below) straight up and down.  Thus, we should try and keep this design structure in mind.  The easiest way to accomplish this is to keep the stock 13B-REW engine mounts and weld in a new crossmember toward the rear of the FC3S engine "cradle".  There is just enough space to weld in a 3" crossmember, and getting the 13B-REW engine mounts to mount nicely is pretty easy.  This allows you to keep almost all the 13B-REW components.[/FONT]
 
[FONT=\'Times New Roman\']The optional method to welding in a crossmember is to drill and tap the 13B-REW center housing to accept the stock FC3S 13BT passenger engine mount; three M14 x 1.50 holes need to be drilled and tapped into the underside of the center, intermediate housing of the 13B-REW engine to accept the three 17mm bolts that secure the bottom of the engine to the passenger side engine mount.  This requires a custom oil pan or the stock FC3S 13BT oil pan.  The stock FC3S driver\'s side engine mount is secured by two nuts on already existing studs on the 13B-REW.  The passenger side engine mount is mounted in the middle of the engine, necessitating the oil pan change.  If you decide on using the FC3S 13BT oil pan, you need to seal the front edge of the 13BT oil pan, as it\'s longer than the stock 13B-REW oil pan by about 1/4". `


[FONT=\'Times New Roman\']Once you take care of the mounting problem, the rest is pretty easy.[/FONT][FONT=\'Times New Roman\']  An FC3S clutch can be bolted onto the FD3S stock flywheel if on a budget.  The stock FC3S transmission should mate with the 13B-REW with very few problems; if the 13B-REW came off an automatic transmission equipped chassis, there is an extra bolt hole in the bell housing, which will not mate up with anything on a stock, 5-speed FC3S transmission.  The FC3S starter should fit with little fuss.

If you\'re going to run a stock FD3S stock ECU, you\'ll need the engine harness, ignition system harness, ignitor, and all coils from the FD3S, minimally.  Going to aftermarket [/FONT][FONT=\'Times New Roman\']EMS[/FONT][FONT=\'Times New Roman\'] fuel and ignition control gives you more flexibility but may require additional ignition components.  Choosing a Haltech EMS for control will allow you to use the stock 13B-REW ignition input (trigger wheel and magnetic pick-ups) and the stock FC3S coils/ignitors!

Due to the 13B-REW already using a front-mounted intercooler, this will pretty much require you to do the same.  This would probably be one of the most expensive aftermarket components to get this conversion completed.  A popular option is to run the GReddy elbow into the throttle body, as this is a polished aluminum piece versus the stock plastic pipe.

An upgrade fuel pump is almost a necessity, as the 13B-REW uses 2x550 + 2x850 versus the stock 4x550 on a FC3S 13BT.  A Walbro 255lph is more than adequate for this application.

The radiator hoses are slightly different for the 13B-REW, so mating up with the stock FC3S 13BT radiator will take a little custom work.  "Universal" ribbed, radiator hoses can be used as a cheap alternative.  It\'s highly recommended to get an upgrade radiator if you still have the stock unit.  The GReddy pulley kit is another option to slow down the radiator and alternator a bit and comes with it\'s own special size belt.

Stock twin turbos will easily fit into the FC3S engine bay, but a custom downpipe is required to fit with the rest of the FC3S exhaust system.  You can stick with the stock intake system on the twin turbos which will minimally require a pair of cone filters or equivalent.

Oil lines will need to be custom made to fit the 13B-REW oil fittings to the stock FC3S oil cooler up front.  The front oil cooler lines is close to the 13BT set-up, but the rear oil cooler line mounts higher up on the engine by the oil filter.

looking good mate comming on nice

[apex_lt]

Any progress? i know hat outside is -15 degree, but maybe something is going on?

[McPie]

nothing yet, polishing on lonely evenings that\'s all
a little bit feel tired after work...

[apex_lt]

Remember the challenge you offered? :WaveBye
posible i will be first :3gears-lh
Course still have lot to do, but first time i saw light in the end of tunnel :Hammer

[McPie]

yea Sure
but it\'s a little funny
RX-4 with OTTO engine and mazda 929 with ....el engine

[apex_lt]

McPie - i have 929 to, it\'s not rx4. only in future it will probably get rotary engine.
