LS2 oppopinion : RX-8 or G8

15k Daydreaming: both of these are powered by same engine (LS2) & same transmission (TR6060 or 6L80e). Which one will oppo get.

Obviously the rx8 needs major work to be swapped, and to get the tr6060 manual into a regular g8 needs work (FYI G8 gxp manual are still 25k+). But either direction is easily do-able under 15k.

Go oppo

I’d just swap the LS into my Trans Am so I’m of no help

Two very different cars with very different intentions. So hard to say. Also, if I recall correctly, it is A LOT of work to make a TR6060 work in a G8 GT. I don’t know of any successful swaps.

both of these are sporty GT cars that got 4* doors, no ?

the swap in either direction is easier than you think ;)

If you’re just going to swap the RX8, I’d just get the G8. Less work, less problems, and when you add up total cost plus labor (And yes, I factor my own labor hours into a purchase), you will probably be around the same amount.

Of course you could buy this RX8 which is already swapped for a lot less than a G8 GXP: https://pittsburgh.craigslist.org/cto/d/2004-ls1-swap-mazda-rx8-rx-8/6227618888.html

Isn’t there an off the shelf kit for the RX8? I know I’ve seen one for the 3.6L DOHC V6 that GM uses in lots of things (LFX if I recall correctly). That wouldn’t be a terrible motor either.

thats why i say daydreaming :(

I am doing a LS miata now, hit some road block / bored at work / browsing different car forums ... you know how that goes

08/04/2017 at 11:40

the LFX sounds really good and all

but for all the money being spent towards a swap, might as well get more base HP out of it

RX-8. Motec instrument cluster, strip the car, Recaro buckets, Volk te37sl wheels, full race coilovers, aero bits to go with that, straight pipe, roll cage. Done.

I do think the ‘signature’ Pontiac bumper / hood is overkill

the holden got much more a sleeper look that I like

One has room for three adults in the back and the other... doesn’t.

It’s also very difficult to swap anything other than a GXP-spec TR6060 into the G8, so consider the added cost for one of those.

Master Cylinder > gawdzillla
08/04/2017 at 12:04

True. I just tend to like the smaller, higher-revving motors over the big lopey ones. Not that there’s not plenty to love about a big stonking V8, that is.

It’s probably cheap to source an LFX since they’re nowhere near as in demand as the LS and they were put into loads of different vehicles. Whether the cash saved on the purchase of the engine is enough to offset the lower output, I dunno.

08/04/2017 at 12:05

its more / less as difficult as engine swapping the rx8 ;)

RX-8. (Or LS-8?)

Light weight, torque, manual trans, and an actual usable back seat for my kids. (Yes, the G8 has a back seat too, but it doesn’t have suicide doors.)

if the swap wasn’t done 1/2 assed it should be a better daily

who needs to carry 4 other full sized adults around all the time anyways right ;)

True that. Plus, having a coupe discourages people from wanting to ride with you.

Makes sense. I think I just don’t buy into the whole Miata hype

08/04/2017 at 15:43

Haha fair point. Part of me kind of wants to see a German engine in a reliable Japanese car though. Just the amount of butthurt would be amazing. And the driving experience would just make it spectacular.

this is what you do if you want to see butt hurt:

buy a 2018 camaro zl1

buy a 2018 miata

swap the drive train with each other, daily the camaro, track the miata

I like where this is going. I would track the Camaro with the Miata engine for maximum butthurt.

G8 all the way. The FX-8 is fugly.

I’d rather have an LS powered FC RX-7 though ....

You’re forgetting most bros can’t afford or won’t buy something to make their car look nicer. Go fast parts and sound system yes. Brakes, suspension, and exterior no....

08/08/2017 at 12:11

last i checked a bro could easily afford a few badges and a front bumper. and usually if they can afford go fast parts they can afford body mods. then they hop on instagram and show off like”hey look at my Australian car in america”

I have only seen a handful of G8s with a Holden front bumper cover. Have you ever priced one? They are fairly pricey. Look up the prices from JHP. I saw a silver G8 GT yesterday afternoon that was loud and quick, but needed a bunch of cosmetic work.

Sampsonite24-Earth's Least Likeliest Hero > AfromanGTO
08/09/2017 at 11:32

considering bros will regularly spend 40+ grand on their bro trucks and bro wrxs theres no doubt in my mind a bro could afford an 18k dollar g8 gt and a 2k dollar bumper cover

That’s 2k they could spend on vaping, protein powder, and eye brow waxings.
