Yank V8
I've never seen a V8 in an RX8 other than that one in Iceland referred to earlier (and I noticed he never responded to any requests for information). The RX7 is often modded in that way and an RX8 might be fairly easy too, but there's seemingly little experience of actually doing it, even in the States.Maybe I've just missed all the V8 RX8s, but I suspect there's something more to it.

A guy in Birmingham has converted at least one RX8 to an LS1 and several RX7 FD's.
His name is Craig Taylor but I can't remember his company name.
IIRC he charges circa 10k though and you can buy an LS1 Monaro for less than that.
Craigs company is "Dyno Torque"His name is Craig Taylor but I can't remember his company name.

He charges 5k plus the cost of engine and box
I know there has been a few SR20det swaps into the rx8, seems to make sense to me, i know its all about low polar inertia, low centre of gravity and so on, but a 3/4cyl turbo/v6 in the rx8 (mx8?) would, i'm sure have seen it a massive success, i guess it wouldn't have these crazy low used prices though.
As far as i know (and this goes for the new mx5 as well) its almost impossible to get the dials etc to work with the new engine, so you really cant be expecting an OEM style driving experience with an engine swap. Though i guess it'd be an awesome excuse for a posh stack dash!

I disagree. I dont think a 1300 kg car will be all that sensitive to an additional 20/30 kgs in the nose. Nothing that some mild suspension adjustments wont sort. Its Mazdas refusal to let the rotary die thats the reason they used it in the rx8. The technology for a light pressure turbo setup with the same power output was there but they chose not to do it.
The rex is sublime in every other way so fitting a proper engine in it would be very worthwhile. Why not buy an mx5 turbo? Well the whole point of the rx8 is that you get rear seats and a reasonable boot so practicality is unrivaled in a 4 door with the level of handling that the rx8 has.

Liking that v8 with two huge turbos...
Op what sort of bhp/tonne are you after and what's your budget? I don't think your going to make any money on this in fact it will cost a lot to do and also the end result will be appealing to such a tiny number of individuals it may be highly difficult to sell and nowhere what it owes you.
Anyway hope you do it I'd opt for V8 POWER and might want a supercharger why not

Has anyone put the 2.3t from the 3/6 MPS in an RX8? At least they're from the same company, so might work a little easier.
Easy 300bhp too.
Is it the same block as the MX5? putting a FWD engine in a RWD car is often not that easy...Easy 300bhp too.
To be honest, until this thread I'd never heard of anyone successfully putting any other engine into an 8. I guess, unlike the 7, they may still be too new (and expensive - despite their relatively low price) to act as the base for a project car.

I had a mazda RX8, the engine is completely crap and I was always wondering what else you could drop in when it inevitably blows.
I would have a good look round for a 4 pot turbo engine that looks short enough to fit. Renaults Megane R26 engine would be ideally suited to the RX8. Something like that is really what the RX8 should have been made with. The very slight weight penalty will be more than worth it.
Just buy a BBR Turbo MX5 if that's what you want...I would have a good look round for a 4 pot turbo engine that looks short enough to fit.

Where did you find that? Looks amazing, although it seems to have an open water pipe - are there shots somewhere of it finished?.M.

plenty of pics and vids in that thread
Do you think it knows how to cope with corners?

LSX engines are very lightweight and compact... one of the reasons they are such popular conversions
Maybe, but one of the reasons the 7 is a good candidate for a V8 is that the turbo plumbing weighs nearly as much as the engine itself, which isn't the case with the RX8, so without decent suspension work it would handle horribly.BTW, what's up with the 4x4 ride height on that blue V8 RX8?!?!
