Hell nice project and all but whats the point when you can't get that power transferred to the wheels in a controlled and synchronized manner...

^project is far from finished. some more work and it will be not only powerful but controlled as well

.......hopefully.

currently looking at a rims...here are the specs I'm considering

295/45/18 10.5 w/35 offset...will stick out 1 inch and is 1.5 taller then stock
295/45/18 11.0 w/30 offset...will stick out 1.5 inches and is 1.5 taller

So with 11 inches of tread on the ground I hope I'll be able to pick up some traction...plus taller tire helps as well.

But as far as putting down the hp...actually...if you watch the first video..is sounds like shit...but I to a take off from a roll of about 10 and even though I'm spinning a little I shoot off pretty quick. The road is a back road and it's not like it's a clean road plus it was only like 60 degree's out that day.

So if I up to a 11 inches and use a set of nitto tires. I should be able to pick up full traction.

I'm currently running 265/35/18

11 inch wheel with a 30-40 offset with a 315/35 and you will still probably need a roll/pull if you lower at all.

he doesn't want a shorter tire. Those are gonna stick out so far past the fender it won't be funny.

oh and since I'm going with a taller tire the 295 is about all the wider I can go without rub. If I didn't go taller I could easily do the 315 or bigger

Oh car isn't being lowered...with the setup...my motor is actually maybe a 1/2 lower then the rest of the car..so the car is being raised. I did have it lowered and now it's getting raised to about 3 or 4 fingers between the tire and fender well. I like the look of sitting low..but around here with these rough roads...low is outta the question.

I'm redoing the suspension. From what math estimates I have made and I'm going with 450 lbs shocks in the front and 305 in the rear.

I currently have zero wheel hop with my current set up. But I can also feel the ass end bottom out between the shift from first to second.


If it wasn't for that happening I think the car would hold traction with these tires...it's just that bottom out and then it's sideways lol.

But hell......I'm still yet to fine tune this engine. I still need a bigger fuel pump...I can get on it in first and then second...but by the time you hit third its dieing out do to the lack of fuel.

A 315/35 on a 11" wide wheel with 32mm-40mm offset would fit with a roll and pull.

People are running 10.5" +45 with 275s with no roll/pull. You could run that same 10.5" moved 10mm out and stuff a 315 with a roll/pull.

Doubtful but please prove me wrong.

Provide me the tires/wheels and I will. Unless you have been under the rx8 and have test fitted aggressive wheels/tires, please shut the fuck up

Lol is all I will say.

I have the S-tech and am running the 265's and they don't even come close to needing a roll/pull so I can see the 275's even on the 50+ rim.

But anyways if I'm going to run a 295 that is 1.5 inches taller without a roll or pull... I'd hope you can get the 315 in there.

i just wanted to let everyone know things been going good...just been really busy...But anyways things should start coming along with my car in the next couple of weeks. I'm taking a new job....I start on monday and i'll be making almost twice as much...but it will be 50 to 60 hours a week. So I'll be extremely busy...

Anyways on to another note. Teagan was born today at 8:33 a.m. she is 22 inches and healthy as can be. Cries very little seems to be pretty content and cool. But I plan to hopefully with this new job in a month have the car build and finished on the road and hitting the track.

congrats on the newborn

:scratchhe :scratchhe :scratchhe

Congtratulations on the new addition (not the car)!

congrats!

thanks guys.

Traction?
Not without drag slicks....

You really put the "8" in RX-8!

He removed the R from RX8.

First gear...no not really traction but it still hooks up pretty good. The Nitto 555 tires in the size I have them hooks up pretty nice....

Think about it...look it up on the net...my tires are a lot bigger then the Vet tires...when I had the tires put on the rim they asked what truck I was putting them on cause they are so damn tall. I'll actually post some pictures and video of the car this weekend when I actually have time to just drive and video it. But all in all I love the way the car feels with the V8.

A couple of the guys with the LS1's say there isn't any traction or this or that but that's cause they haven't added the tread. When your talking a tire that is

5.84 inches taller then stock

and

a tire that is 1.75 inches wider your talking some serious change in grip and gear ratio.

A 5.84 inch taller tire is good for like say 1200 rpm... IDK I'm just throwing numbers...all I know is the car is insanely quick and it handles great...has a awesome feel and sound.

It's really what the RX8 should have.

Once you go V8 you'll never go back lol

God I hate that you did this to an 8. I mean, to each his own but this just bugs the hell out of me. :(

I'll tell ya what...you hate it...but how about you come down sometime and hop into the passenger seat...your heart will be pounding and you'll have a smile ear to ear.

One ride will change everything.

I thought boosting 15psi and having 400 whp was fun and exciting......try having 500 but having torque as well threw the whole curve.

It just stops here?

It was sold, then resold, then hopefully pushed off a cliff. This has to be the worst swapped RX-8 ever.

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 Shit 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?

:lol::lol::lol::lol::lol::lol::lol: this thread is more dead than that pos swap

this is dope

Looking for V8 SBC RX-8 Swap info
 

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.
