Argh, true. But as you say no aftermarket, and most of those V8s are physically larger than a pushrod small block. Not all, but seriously who chooses a rover V8 these days?

Cakefool posted:seriously who chooses a rover V8 these days? You're correct. The majority of V8's which I see going into other cars these days are 1UZ's from LS400's. When you can buy a complete, running LS400 for £400, it's a no-brainer. The supercharged Jag 4.0 from the XKR is cheap at around £600-£800 though.....

Haha wow. Reminds me of the 4.6 vs. 5.0 pic. An FC with an LS is probably the best budget swap there is. Although RX8's are getting cheap as hell now too.

See if it were possible to get an RX8 that didn't look like an RX8 I'd be fine with it but it's just a dull looking car that's aged pretty badly. ...but what does UK law say about doing something like Roadkill's Vette kart??

Too many sharp points and small radii. Check the SVA rules, they're actually pretty clear in most regards. I'm familiarizing myself with them for a project  E: it could be done but it wouldn't look like that

RX-8 talk is worse. Just let that ugly piece of poo poo die so I never have to look at it again. I want to think Mazda never made such an awful design by committee car and they stopped on the high note that was the FD3 RX7. The only good thing the RX8 did was give us a platform for the NC miata. Even the loving fender flares that ended up on every other Mazda were an affront to me.

Cakefool posted:UK goons: LS are rarer than rocking horse poo poo, what else is available? V8? 1UZ, 3UZ, M62, any old rover v8 (most popular, mostly carbed, most of the previous generation would put these into cars) I6? 1JZ, 2JZ, 7M, RB25/26 I4? 4G63, SR20, K20 Plus a million other less-well known engines that people have just pulled from cars because they are cheap. The old Vauxhall Omega and Ford Scorpion V6's are popular. You will see more Aston and Jaguar V8's than American motors. Chevy small-block or 'LS' series, Ford V8's, etc are almost non existent....because cars containing these were rarely sold over here (only example I can think of is the Monaro, which was not a great seller). Our larger 'trucks' and vans, which use V8 gas engines in the US, are all 4cyl turbo diesels over here.

Super off-topic, but I have an irrational desire to build a turbocharged 2.5L MZR-powered Rx8 someday. The motor bolts into an MX5 subframe, which bolts into an Rx8. Not sure if the firewall survives, but most everything else should Lego-brick together. I think the Rx8 has a cool form-factor and they've always been described as an excellent chassis, but the engine...

It's too bad it's hard from an emissions standpoint to swap an earlier 13B into the RX-8; every other aspect should be more or less cake, but because it's an OBD2 chassis, doing it as a street car is problematic.

BloodBag posted:Wouldn't a renesis in an NC be a more...interesting use for that motor? I always thought so, but a lot of people bitch because the renesis isn't boosted. "Oh no," they cry, "real rotaries are turbocharged!" ignoring most of everything sold before '93. Sure the renesis has its issues, but it makes enough power to be fun. Personally though, I'm looking at going streetport 13B into NA, due to emissions laws ... well, and the number of streetported 13B parts I have handy.

ShittyPostmakerPro posted:Renesis in a fire pit would be better use of that motor. It's not a bad motor as per say, how Mazda did emission and cold start are the problems. As I understand, the Renesis is actually the best 13B esp if you want boooooost and you can address the issues reasonably easily, albeit illegally.

As I understand, the Renesis is actually the best 13B esp if you want boooooost and you can address the issues reasonably easily, albeit illegally. It's a pretty good NA engine for near its stock power output or a bit more with a standalone and some tuning, as long as you're not roadracing. The way the exhaust ports work, the spring behind the side seals are exposed to a lot more heat transfer from exhaust gases, and if run really hard for a while they give up. And because the exhaust flow is a lot less sudden than the older style exhaust ports, they won't spool turbos the same way. And there's a water jacket right near the exhaust ports, so you can't make much more power without doing weird things like having the old *and* new style exhaust ports by mixing and matching parts.

From hearing from pro teams back in the day, and club racers more recently, if you run the things at 10/10ths on a track, the side seal springs lose their temper and go off in about 50 hours (IIRC). This isn't really that bad, as the springs are pretty cheap, but it's a failure mode the older 13Bs didn't have - I've been looking at everything from the point of view of building a roadrace car lately, and given one engine option that I have to refresh more often, I'm going the other way. Think of it this way - assume you're starting with a good engine and you swap it into something, meaning standalone, and fixing the conservative oiling. Now you have something where you can basically overlay the graph with an F20C and match it, except smaller and lighter (I have scaled 13Bs at 250, supposedly the Renesis is 275 dressed and the F20C is 325 in similar condition) and that bolts to any transmission that bolts to a rotary. If I didn't have a bunch of hairy balls out ported 13B parts sitting around (well, and I like building engines) I'd look for one for street use to drop in a Miata. The older style 13Bs have more potential in a radical NA form, or when boosted, but the Renesis fills a pretty nice niche.

Maybe for someone that knows their way around a rotary, like Spyder, but I'm guessing even he wouldn't bother with a Renesis. And for the layman it's gotta be a hell of a lot easier to just swap in a pushrod V8 with a swap kit and be done with the Renesis. I know that pisses of the RADL but it is what it is.

What the hell happened in this thread?  For the record, I've seen exactly (2) well done LSx swaps in Rx-7's here locally. Every other one of them was a loose bolt away from the motor falling out or catching on fire from sketchy wiring. If even 50% of the people doing these swaps knew what they were doing, I'm not sure I would care. It's just terrible to see these (or any car for that matter) getting hacked up because V8 BRO. I honestly doubt FD swaps will become more popular as these cars get older, rarer, and out of the "affordable" swap range. Once a rolling shell is above 10k, you might as well buy a $25k Corvette. It would be cheaper and easier to maintain. On a personal note, I would love to swap a early 996. Oh and the Renisis sucks. I fully expect to see a plethora of LSx Rx-8's in the near future. You can pick them up for so drat cheap ($1500 for a 05 with "Motor problems").
