LS1 FC Has any one done this personally or know some one personally?
 

Thinking about LS1 conversion in FC and want to hear how it is from people who has done it.

search function, and they have a section for other engine swaps under the rotary performance catagory.

i knew someone that has done it....

he SCREWED me out of $150....

bastard.

Torquecentral.com or .net or something like that... Whatever that site is for quitters.

I know someone who has done it. Got a ride in it and decided to convert my fd, 'nuff said.

Yeah check out torquecentral. FDreaming, care to line up with one of us "quitters" :D ?

ask away.
ls1t56 fc in progress.
its simple really... but the prep work is time consuming.

Interesting opinion ya got there. Keep on enjoying your 13 second, gas guzzling, temperamental rotary and we'll take care of the fun stuff, ok?

What are you preping?

dropping in the LS1T56 only took a few hours.

BUT, the fuel system upgrades, cooling system upgrades, drivetrain upgrades, suspension upgrdes, wiring changes, even the intake planning and finding the right parts for cheap are all adding up to being very time consuming stuff. I even missed a lot of basic things that made my swap install take a lot longer then needed.... header lower flange bolts were broken off and had to be cut shorter and drilled out, I was missing a bunch of bolts for the bellhousing, I had no rubber mounts on the tranny or engine (tough to get the engine ones), my super duper racing radiator's outlets are each 1/4" larger diameter then the LS1 coolant necks, the diff has to be bolted to the rear subframe before attaching either to the chassis because I reinforced the sub-to-diff mount plate, the cherry picker load leveler (tilter) that I bought was a piece of junk, etc. etc.

There is no wonderful write up of a LS1T56FC how-to... yet.
so it took some time figuring everything out because I want to do it myself for as little money as possible while buying quality parts.

I've ridden in an LS1/t56-FC.

I can describe it one word....

DAMN!

Basically stock LS1, not even really tuned completely, and it would kick it sideways at the drop of a hat, anywhere from 0-60 mph range. Feared for my life a little, but damn, hell of a car. :bigthumb:

We should do to him like we are doing to GG.

where do you guys find these incredible avatars?!?!?!?

either they download and make them or take a picture and make them.....

Wow, hold on, your jumping to conclusions, I drive an N/A rex so I run high 14s, but I do get 26mpg so... I am right in line with an LS1. As for lining up with a V8 powered rex sure, on a road course, first one to understeer loses! :P

Don't worry I realize that if you just want captain insano power levels the swap is the cheapest and fastest way to get there, but this site does focus on ROTARY performance so take your enthusiasm over there.

I assume you have the requisite suspension mods to back up that statement? There are plenty of guys with swapped cars that have the proper suspension setups to make up for the massive 50 lbs of weight they've added up front. :bigthumb:

1) sure your right in line with an ls1 in mpg only it will run mid 12's.

2) seeing the car will handle no different you might have to worry more about oversteer due to something called power. Have you heard of that word?

3) I like how you like the rotary is god. My jetta 2.0L 8v beat my RX7 automatic 0-60. Sure "it an auto" well you shouldnt need to rev to 5 bagillion rpm to get 100 hp. f*** that.

4) the cost of and ls1 isnt too far from a rebuilt motor and rotary upgrades only it would have better results.

5) Fuck off and die. :bigthumb:

:rolleyes: My truck can run 14's if I want it to. There's a big difference between high 14's and low 12's. Your car has NOTHING in common with the LS1 except the chassis. My FD/LS1 swap is in the works right now, and I intentionally set my FC up to go in a traight line. But I'm sure there are a few FC or FD LS1 owners who will compare lap times with you.

There is nothing insane about a streetable 400rwhp LS1. I want my powerband where I can use it, which is daily-driven, on the street. Something very few 400hp rotaries are able to accomplish.

I also realize the SITE leans towards rotaries, but THIS SECTION of the forum deals SPECIFICALLY with OTHER ENGINE CONVERSIONS. So you can take your enthusiasm wherever you want but trying to call someone a quitter because we want our cars to perform better and more reliably is a pretty stupid argument. My car will still be running on it's original piston motor while you're on your 2nd or 3rd rotary. So it's your engine that will quit, not me.

I just had to come out of retirement for some of this!

Was that supposed to impress us? My minivan would eat your car alive fucktard! :bgfuk:

You`ve wandered into the Dark Side of the RX7Club and the force doesn`t appear to be with you. I suggest you go back to your side and gather up all your little buddies with little motors to come back to completely hijack this thread. :asshole:

Toughguy :)

How does high 14's and 26mpg compare to an LS1? In a fbody they run high 12's stock, in a FD they run high 11's stock. As stated MANY times before the LS1 setup is only about 25 lbs heavier, wow that causes tons of understeer :rolleyes: Go to a mini battery and you just about break even.

How is the LS1 a cheap swap? The average cost has been $8-9k to do it yourself and it takes alot of knowledge!

I do NOT have a LS1 RX-7 but as a respectable person I respect anything that is fast and makes sense.

Now you do understand you're on a RX7 forum and not a Rotary ONLY forum right? Also you do see you're under the "Other engine conversions" subforum so if you don't support swaps then get the f*ck out!

- nicely put GSRsol!

some proof! \/ \/ \/ \/ \/

I just got the car on the road and I was able to weigh the car before and after the swap.


1993 touring modle 5-speed

Before

LF 729 RF 695
LR 705 RR 692

Total--2821lbs

After swap 1999 ls1/t56 trans ac and power steering

LF 748 RF 717
LR 683 RR 700

Total weight 2848lbs


Weight gain only 27lbs

this guy i guess still had the battery in the engine bay. I plan to not use AC, power steering, ABS, windshield wipers, wiper's resevior, wiper motor, light ass exhaust, mini battery, no rear windshield wiper, fuel cell, no airbags (momo wheel), and probably some other weight reduction. Trying for 2700lbs without driver. thats just me tho. :-)
All he needed to do to weigh less than a stock FD is dump PS or AC....
Relocate battery to the rear and 50/50 is DAMN great for what it is...

/\/\/\/\
just one more to prove the LS1FC or LS1FD is not a fat pig of a swap!
but some rotary guys just wont believe it, its so sad they are brainwashed by mazda advertising!

they need to follow step five of what i posted above.

My "pig" on a scale after the LS1 swap. :D

Damn, I thought you guys might have recognized the sarcasm in my post after I started with "my car is a 14second N/A rex that barely manages the same MPG as an LS1". When I first posted in this thread it was posted up in the 2nd gen forum, it got moved here to engine conversions, so it was still in the "rotary" side of the equation, I didn't realize it got moved over here(I usually just search for threads I've already posted in when I don't have alot of time to waste on here). I bought this car for a challenge, I wanted to play with a rotary motor for a while(I.E. there is an M90 supercharger sitting on my workbench), if I wanted and LS1 I would just buy a damn WS6. Hell, I had a 94 Z28 for a while there.

And the LS1 FDs would still be handing you your ass!

Toughguy :)
