LS1/6 Conversion for 3rd Gen
Many of you on the board have been following my ever so slow build of a 1993 Mazda RX7 Touring model with a 2001 LS1/T56 conversion. I'm glad to announce that the car will be up and running by the end of the month.
With the completion of the car, I will post more pictures and video of the working assembly.
The wing has been removed.

man.. looks just like a... C5 corvette..
the resemblence is uncanny..
Sorry, but why wouldn't I just go out and buy myself a C5 instead, and leave the right engine (without pistons) in the RX-7.

I guess the answer to that question is one of weight savings: an LS1 7 should undercut a Z06 by at least 300 pounds....will it make that big of a difference at the strip or track? probably not, but it would be very interesting to do a heads up comparison
anyway, I like the idea....as much as I like the rotary, I don't care much for turbo cars, especially in the summer, and all the inherent problems associated with turbo cars (including the increased maintenance issues)
Jim has started a revolution, ha
actually, stuffing a large displacement engine in a small chassis is nothing new

OH MY GOD!!! MY EYES, IM BLIND....I THINK IM GOING TO PUKE
How can you put that horrible piece of **** in a Rotary Experiment 7????? HOW?! That's ******* stupid!!!!! I had no idea something like this was being done...im so depressed, how? HOW HOOOOOOOOOW??!?!?!
How can someone destroy the handling of a vehicle so much?!?!? It must have a 70/30 front/rear ratio now

Ive read many a Jimlab V8 threads, and the weight difference is hardly worth whining about.
I think the weight should be around 52/48 now. I think thats close to the estimate. The LS1 is pretty light.

Actually a LSI probably weighs Less than the 13b-rew.....so what do you have to say now? 
An FD with a torquey aluminum V-8 would be a blast, can you say launching at 2k? 
Good job V-8 Lover, just seeing all those wires hanging from the engine bay scared the **** outta me

than i think you might be an idiot?!?!
You can lift an 13 block with 2 people...could you do that with an LS1?????????????
If the LS1 really is lighter than the 13b I think all FD's should have came with 12a's!
I doubt one person can pick up an LS1.
And I had no idea corvettes were lighter than FD's!!! I bet you think it would be lighter than an FB as well???? And I'm certain, that if you put an LS1 in a Festiva it would have the same power/weight ratio, right?!
I hope this happends to the stupid car:

Ok, #1, dont call me an idiot ever again....
#2, a 13b block along with the two turbos, intercooler, intercooler piping, and other things weights a good amount, Im not sure of the exact weights, but Id say that a LS1 and a 13b-rew, with all of the accessories are within 50lbs of each other. I never said anything about corvettes being lighter than FDs or any other car, did I?? I said that the engine iteself was as light or possibly lighter than the 13b-rew. Oh yea, and it puts out more HP and way more torque....

Hey defprun why do you gotta bash people because what they want to do to THEIR car. I think its a good idea. Like they said above go back and read Jim's post the weight difference is not that much and he is using a LT1 which is an iron block. With the LS1 the weight should be equal if not less since the LS1 weight about 65lbs less than the LT1. How can you argue with more HP and more Torque, put that in a FD and you have one scary fast car!!!

Yea... I want a ls1 in my 87... How much would this run probably. with all of the parts and labor to have someone else do it? Would there be big problems with like torque breaking stuff? And could a supercharger fit on the motor while in a 2nd gen? Thanks...

Good job on the conversion. The LS1 is a great motor as anyone who has ridden in a Z06 knows. I think it will turn out to be a very badass car.
In fact, I plan on putting the LS1/6spd combo in the old 68 Firebird I have in the near future.
Hehe, or maybe I'll put the LS1 in the FD, and the 13brew in the Firebird.....
Anyway..... once again I commend you on the conversion job.

Or here...
I weighed 2 FD motors in the back of my Ford truck on a truck scale. The motors were complete with all accesories, turbos, downpipes, flywheel, wiring, etc.
Weighed the rear axle of the truck before and after.
A complete 13BREW weighs 410lbs (scale increments of 20lbs). I didn't weigh the trans, starter, etc because I didn't have that much time.
A complete V-8 will weigh much more than that, if you strip all the accesories off it and start using aluminum parts then the weight will drop. I've heard a SBC weighs 575lbs with iron heads and I doubt that includes exhaust, PS, AC, Alt, etc.

Rxmfn7 & Gun - Thank you for all your kind comments.
TonyTurboII - The wing has been removed. The engine is being controlled by a stock LS1 computer. The computer has been tuned using "LS1 Edit" to keep some codes from turning on the MIL (Mainly emmision realated).
sirkus - For LS1/6 installations in a 2nd Gen RX7, please visit www.thewrongmotor.com. I do believe there is enough room for a blower install under his hood.
With Regards,

On a serious side note, how are you controlling the engine?

I have no doubt that any old 350 with iron heads weighs a ton. But we're talking about a LS1, which is all aluminum, block and heads. It also has a composite plastic/fiberglass intake manifold. It weighs 66lbs less that a LT1, which also has aluminum heads. A LS1 is not your run of the mill SBC, its quite a bit better.

I totally agree. If the old cast iron SBC is 575lbs, start deducting for aluminum parts. The SBC has 165lbs to lose to match the 13BREW, 66lbs less for an LT1, then it has 99lbs to lose. LS1 has an aluminum block, it's getting close...
My point was, worst case it weighs 165lbs more, IF it was a cast iron V8.

My LT1 crate motor was 476 lbs. with extra accessories, in its crate. My custom crankshaft is a full 18 lbs. lighter than stock, and I shaved another 3 lbs. in my rods alone. Even if that were my only weight savings, let's call it 445 lbs. subtracting 10 for the crate. So in other words, I would have only had to drop 30-40 lbs. in weight from the front of the car (been there, done that) in order to EQUAL the weight of the 13B-REW with my cast iron LT1. Now consider that the LS1 weighs about 65 lbs. less than an LT1, each with full accessories.
My 20B, by comparison, weighed ~561 lbs. on its crate with the cast iron turbo and exhaust manifolds, yet no one whines when someone shoves one of those heavy bastards into an FD... why not? Because it's a rotary engine, and therefore weight and handling (which is absolutely affected, especially if you don't cut your firewall to avoid moving the steering rack...) don't matter because... well... it's a rotary engine. Perfectly logical. Some of you people need your ******* heads examined.

You tell them Jim the LT1/LS1 are really good engines and will make the FD a better car. I've been planning on doing this also but saving up the money is a pain and takes a while when your going to college. But soon
