I thought the point of dropping in a V-8 into an Rx-7 was because of availability? HA! I've searched for 3 months now for an affordable 5spd transmission and have come up with nothing. The price of the 5.0 5spd is redicules, they're selling for $650-$850, so i've decided to put this project on hold until i can deal with it. Most likely around spring break i'll pick up a 5.0 LX 5spd as a donor car for a spring project with the Rx-7, it's just too cold to deal with an engine swap of this magnitude over the winter.

Insted i've purchased a new car for a small project. Something i can work on in class. Here it is.

whats the project going to be and why the 5.0?? trannys are hard to get for that car, plus you should get a 350 parts are easier to come by and the old higher compression ones put out more HP than the 5.0 go 5.7 !!

5.0 HO 225hp same as the 350s with less weight.

What do you mean what is the project going to be...? The AE86 is likely just going to be a project in class, although, i do have a turbo laying in my room and the 86 is carboreated. I know next to nothing about turbocharging carboreated engines, so if someone could give me a few pointers if i decide to, that'd be great.

I used a 4cyl 5 speed in my 82 mustang. The input shaft is the only difference. You will need a different pilot bearing. Much more plentiful and worked just fine.

It will be ran hard, the 4cyl T-5 won't hold up, i've talked to many Mustang guys about it. All had the same thing to say. If i'm going to do it, i'm atleast going to do it right.

Well well well, your project is hung up yet again. How shocking.

AE86s aren't supposed to be carb. It looks like you have a SR-5 trim. The motor is a 4A-C which is a weak SOHC 1.6L motor. The GT-S version came with a DOHC 4AGE 1.6L motor which has TVIS (Toyota Variable Intake System).

Both these engines are EFI, so I'm not sure what kind of carb setup is in the 86.

A really good site if you don't know it already is www.club4ag.com Good luck, and post more pictures!

That Hachi Roku would be fun to play with, big gains in Japan with those things...

rotor vs. piston

As a guy that has a 350 in his 7, I can say that knowing what I know now I would have went with a 5.0. They have a very good aftermarket and the 5speeds are much cheaper than a camero/firebird T-5 and are much more plentiful. The main reason is that you can get a fuel injected 5.0 much easier and much much cheaper than a GM unit. The only down side to both is that they are American engines.

the 4a-c are carbed. a friend of mine had a sr-5 and had a 4a-c carbed from the factory, which he swiched it to a 4a-ge with twin weber setup later

Haven't picked it up yet, only have sent the money. (at a dealership)

As eddie said, it is carboreated, i believe it's a 4a-fe motor though, tough motor, just weak in power.

Not hung up, if you remember, my initial project was to buy a new car. Purchased a new car, next project is chopping the roof off my Rx-7. Bad idea that's never happening.

I have heard many people say this. Every one of them are GM guys. And let me guess, Ford parts are more expensive too, right?

stinkfist

I don't understand. Would it be better if it where built somewhere else?

Is it not as durable or as reliable as a rotary?

Are all motors built in america inferior just for the simple fact that they are built in America?

I drove my 305 Camaro 15 miles without a water pump nor fan (belt snapped) on a 90 degree+ day, 3 of the miles were stop and go traffic. Engine is still in perfect working order.

You talked to the wrong mustang guys. All t5 transmissions 86 on where world class. They are all made from the same material. The only reason the torque ratings are different is because of the gear ratios. The 4 cyl t5 have lower 1st gear. Most in the 4.0 range where the v8 version started at 3.35. Quite a fewq of the Factory stock racer used the 4cyl version just for the gearing. They where putting down 300+hp and running in the the mid 11's.
The only problem is the input shaft is slightly smaller, but pretty much any autozone.advanced will have the one that works. It is Motormite 14672.
I ran a stock 4cyl T5 in my 2.3turbo mustang for two full seasons with probablr close to 250 1/4mile passes all on slicks. With mist 60' being in the low 1.6 to high 1.5's. running high 11's. Not to mention a bunch of street driving It would still be in the car but a bearing started to whine. And because of what you think and most the 5.0 guys who don't care to learn about things the 4cyl T5 are cheaper to buy than fix

Also most T5 failures are more of a driver failure than the trany.

If you plan on making enough HP to where the 4cyl trany would be a major worry, better start thinking of a Tremec or better yet a G-force T5

You also have to remeber that a stock transmission that will hold 11's in a 3400# car will take a whole lot more abuse in a 2300# car.

BTW, I'm also running a 4cyl t5 in my rx7

Wish i would've known the truth before buying a car...

I've been beat to it.

Why don't you and Chef go work together on that 4 rotor Bonneville record, and get back to us.

Haha, ouch .

EDIT: As a side note, Im glad no one has such disbelief in my project, even with as astronomical as it may be, lol.

Oh man I almsot forgot about that! Chef has run into some bad luck wiht soem things though if i recall correctly :[ Bar code man on the other hand.. Go get yourself some Tony Robbins tapes or some ****.

O 16581 72452 5

No this is going back to my first, i've only had 3 "projects". Buy another car, chop the roof off the 7, drop a v-8 in the 7.

I'm down to only two realistic projects and have done one, now i can save up again to get the engine in my car. I will now have a nice daily driver to get me around before and after doing so.

Who is Tony Robbins?
