Izuzu V6 has to be one of the worst swaps then this. This isnt too bad

 

Nah the Isuzu swap will never actually happen. This death trap actually ended up "finished".

 

I'll Admit The Swap Wasn't As Good As I Wanted. The V8 Adds Lots Of Weight And The Suspension Can't Handle It. Doing A V8 Will Make You Alter The Steering. You Have Two Choices On Engine Position Up High Or Tucked In Low.
Tucked In U Really Need To Go Dry Sump.

If I Was To Redo It I'd Do A Supercharged 4.3...It Would Save A Lot Of Head Aches.

In Yes This Car Has Been Sold A Dozen Times And Had The **** Ran Out Of It.

 

If I was to do a build like that just would have turned it into a straight line monster. At least you attempted something. I know I will be in the future prolly 5-7 years. Alot of threads are out dated on here. I wonder if Hinson is good whith their swap package for the lsx.

 

The Way I Look At It... Is The Professionals Have Spent Years And Aren't Offering A Lsx swap. So It's A Little Tougher Then It Looks. There's A Lot Of Issues Between Weight And Size

Why I Say 4.3.Wouldn't Have To Move Steering And Weight Would Be Close To The 13B.

 

The professionals have no issue doing it, it just cost more cash than the average RX-8 owner can afford to do it right. The rest have mostly turned into unfinished half assed monstrosities.

That's a very clean looking conversion. Love that hot air intake. Nothing like 220 degree intake temps to improve performance. (joking!)

Do not love the maple syrup brake fluid. All that effort and money and they couldn't bleed the brakes to make sure the thing can stop?

 

Looks like you're really stuck on the weight issue, I suggest you do a little research and look up how much a ls engine(aluminum not cast iron) weighs. At least then you'll stop posting on how much it'll change. While doing your research also look up on how much the stock 13b weighs and throw on a turbo kit as well. I seriously doubt the 4.3 engine you're talking about can be measurable to the ls and 13b!

 

Ok I know it's been a while since there was any activity on this thread. But I just read the whole thing and the videos won't work. Is this guy still around. I want to see this in action

 

Read.

 

Best laid plans and all that. I think an 8 is just too much for this car, and carbs, well just say no..

 

Where you at on thit?

 

this thread is more dead than that pos swap

 

this is dope

 

Seems like everyone is putting in LS motors but I'm kinda old school.....I am putting in a SBC 350 with a 700R4. Looking for any and all info I can get to make this happen. I would like to use the electronic steering but I don't have a wiring diagram and I know that most everything on the RX8 is controlled through the body module. So many questions......I guess a wiring diagram would be great to start with if anyone knows where I can get one, then there are the gauges and warning lights. Any help from anyone who has been through this swap or even the LS swap would be great. I would like to put the motor in once and not have to take it back out to modify something I could have done first. I have already installed the bump steer kit and put in the motor mounts, that's about it so far. Not interested in why I should have used an LS....they are great motors but that isn't what I am doing here, going with the SBC. Any info anyone has would be appreciated.
