Carb'd 12A 1985 AE86 Coupe build in the Lonestar State

dr.occa · 09-16-2011, 10:54 PM

Picked this rolling chassis up about 2 - 3 years ago in San Antonio. I'll keep the dialogue to a minimum for the time being.

These cars never came to the States in a Levin format so here are snippets of parts to convert the US Trueno to a Levin.

The TRD replica Group A/N2 wing my daughter is holding is obviously just a luxury.

The factory Toyota brackets needed to mount the headlights accordingly graciously provided by a buddy (Aaron Rue a.k.a. Hondarue).

Some of the parts mounted.

I'll be the first to tell you I'm horrible with welding. I'm especially worse when it's with a cheap Harbor Freight wire mig welder.

I decided to try and rig up a hood by using spare flip up head light covers to weld up an appropriate hood. It's going to seem some bondo if I do go with the hood.

More turd welding.

Picked this up for $200 from the same kid I got the chassis from.

Engine bay rattle canned.

Power plant in.

Aero mounted. You rotary guys have some killer affordable rads!

Oil lines ran...

...and cooler mounted.

Then...

Today, I just finished up the DLIDFIS ignition setup. A big thanks to Rotary Car Club (AND RX7Club to be honest) and especially Master Chief from Tulsa Turbo for the wiring and explanation of how it operates.

GM HEI Modules

2 Accel Coils 1 for each leading plug. 1 to the distributor for the 2 trailing plugs.

The hook ups to the magnetic leads in the distributor. I finished up the alternator wiring into the SR5 harness as well as evidenced in this pic.

i like it....the welding looks good to me...

You may not like your welding, but at least you're doing it yourself. Truly home-built.

WE3RX7 · 09-17-2011, 02:40 PM

Nice. This is the 2nd AE rotary powered project to come across this board... I'm liking what I'm seeing so far.

Good luck man... and bonus for doing most of it yourself!

How the trans sits down under:

Hockey puck pieces drilled.

Today, I drilled out the original fuel return hard line on the tank cap and welded in a 3/8 stainless 90 degree. Pardon the welds.

Running a Carter 4070 under my custom port-a-potty toilet lid:

3/8 fuel return routed:

That's a wicked cool build man! Good Luck! if I lived anywhere near you,
I would be honored to assist you with your labors, for car love.

Progress:

Some shots of when I was installing the mini-spool:

Here I've got the diff already out of the carrier and the ring gear and side gears & pin removed.

Here's the differential with the mini spool snuggly entombed in it ready to do what it was born to do: THRILL!!!

We'll have to see how the stock SR5 axles hold up to the "throttling" they're about to get

.

BC Racing rear springs

AJPS adjustable rear spring perches

Fuel pump and fan relay & switches

Fans and shroud mounted, wired up and running

Updated furnace shot

SR5 driveshaft (lengthened by an inch) slips perfectly into the RX7 transfer case

The I.D. and spline count of the split yoke are identical - 20:2 spline count.

Complete SR5 factory rear end. I installed a mini-spool into the rear end.

Looks nice man, keep up the good work when you get a chance get a better welder and just go over your old welds for a good safety measure.

dr.occa · 12-18-2011, 09:33 AM

Finally got it to turn over with a can of starter fluid and 2 ounces of Valvoline VR1 20w50 down the carb throats.

Needed it to idle for a while to get some Alumaseal in the cooling system with some water. There's a good chance there's a coolant leak in the rear housing. Kentetsu from RX7Club.com had a similar issue and reported nothing but success in solving his problem with some Alumaseal.

I think I just gave myself cancer and went deaf all at the same time though.

Oh! And turn down your volume too before you play the video. You'll die if you don't.

So how did the Alumaseal work out for you? Hopefully it worked as well as it has for me. 40,000 miles and still going strong.

Sorry I hadn't been on here for a while but here's a quick update:
After testing out the Sakura Fab prototype 12A intake gasket on the dyno (see thread here) Engine Logics boss man and engine guru Chris suggested pulling the silencer from my exhaust. So "Mad" Brad Burnett obliged and in 60 seconds the Levin went from...

...to picking up 13.3WHP!

Okay, so I just have to always keep a pair of ear plugs handy when I drive around in this thing.

Already went from F11 e-tubes to F3s and also upped the air correctors a half step to 145 since the dyno run.

Kentetsu. I actually ended up pulling the motor and replacing it with another 12A.

The video is set as private so it wont play for anybody until you switch it to public. Have fun on the rebuild for the sealant, lol...

prrex4ever · 12-22-2011, 10:43 PM

Nice build, good luck with your project.

1twistedrx7 · 12-23-2011, 07:37 AM

cool project !

dr.occa · 01-26-2012, 11:24 PM

Fabbed up a heat shield to keep the heat away from the intake, carb and any fuel lines.
I didn't have enough of a single piece of aluminum to make the seamless shield per my design so I riveted another piece to complete it.
