The ZF tranny from the US M3 should hold up to about 600HP without problems. The Euro versions came with Getrag 6-speeds, which are just as tough as Supra trannies. I don't think anyone has ever made a BMW diff conversion for the Z...

Is your engine fuel injected?

Which length do you need - 133mm or 130,3mm? These appear to be similar to standard L28 rods, which are 130,3mm long.

I wonder if a LHD steering rack would clear the manifold with turbos installed...

Why do you want to stay with the L24? Although I think it should be possible to safely bore it to 86mm, I'd just go with an L28... Are you going to race your 240Z?

CA18DET is a great little motor, but it was never available in the US. Even though most parts (like crank and block) are identical as in the CA16DE, I wouldn't choose this one. SR20 is a nice engine, very popular too - but there are SO MANY OF THEM, I mean, I haven't seen a car that it hasn't been swapped into (maybe except for a Civic)! Plus, the DE motor that was available in the States was used in FWD platforms, which means that it has a different block than RWD cars and the S13/14/15 transmissions won't fit without an adapter. KA24DE looks like the best option here - it's tough as nails, parts are plentiful, plus it's relatively easy to find one, because almost everyone change them for SRs. Dunno why, really...

I'll keep my fingers crossed! I know how it feels when your dad is being operated - my dad had three brain surgeries in Jerusalem... Hope everything goes ok.

http://www.eurotuner.com/featuredvehicles/eurp_0802_1975_bmw_530i_chevy_v8_engine_swap/index.html Found it on Eurotuner.com. What do you guys think?

I don't think it's that important to have a set of carbs from a motorcycle that has similar cylinder displacement to the L-series. Remember that bikes operate at MUCH higher RPM than car engines. I'd imagine that a car engine at, say, 6000RPM and a bike engine at 13000RPM (these figures are only exemplary) should need an equal amount of air to operate properly. Am I wrong?

That's a good idea, thanks! I'll also consider some movie characters' names - finding difficult women in films shouldn't be difficult.

I named my BMW Frank - no idea why, it just seemed to fit. I would imagine a guy called Frank to be cool, and that's what my Bimmer's like. I still have to find a name for the Z. She's a difficult girl, so I think she should have an Italian or Spanish name to fit her tempestous character. Oh well...

Hey Sulio, looks like you're using the Des Hammil book too... I haven't installed my carbs yet, so I can't give you any advice, but why don't you post this info on classiczcars.com? I think that most users here use triple Weber DCOE and Mikuni-Solex PHH instead of Dellorto DHLA, so it may be worth trying elswhere. I'm in an even worse situation, because I bought two sets of Solex C.40 ADDHE carbs, which almost noone knows how to tune (apart from BMW Alpina guys - some Alpina 02-series cars had these fitted). Maybe you should get yourself an Innovate LM-1 with a wideband and narrowband Lambda meter? Tony

I'm sorry if it's off the topic, but I'm curious about one thing. If I remember correctly, the SOHC and DOHC KA heads are basically interchangeable. The KA24DE DOHC head is somewhat more complicated than the KA24E head, as it has one more cam, four more valves, and many more moving parts. If so, then wouldn't a SOHC head based on the KA24E unit be simplier to build and modify? I remember 1_fast_z's diagram showing the differences in flow between standard and modified L and KA SOHC/DOHC heads, and even though the SOHC head didn't perform as well as the DOHC head (especially ported), it was still much better than the L-gata heads. Apart from not having two overhead cams, the SOHC head should be good enough for performance applications. So, would it be worth it to cast such head instead of a DOHC head? Then again, when I think of it, the cost of casting a SOHC head would be just as big as when going the DOHC way... It's just the components that would be cheaper. Any thoughts?

I beleive this style is called Bosozoku, and it's supposed to be a kind of "renegade" movement among Japanese car modifiers. Some say those guys originate from car-based hooligan groups that were active in the 80s, but the style hasn't changed since then, hence the bad taste styling "enhacements"... Remember the days of disco, artificial leather, wild hairstyles among other things? Well, mix it with a group of Japanese hillbilly car nuts and what you end up with is Bosozoku... Cool link by the way, thanks for sharing.

It seems logical this way. Frankly speaking, I find the carbed RB idea to be an ideal replacement for the aging L-gata motors. I'd love to build one such motor someday.

I think I found something interesting... Two carburetted RBs. The orange car is the Rocky Auto S30, while the second one is probably a GC10 Hakosuka Skyline. Both engines look VERY nice in my opinion../.

I'm not that much into the TT I6 mods, but I have confirmed info that you can map a 100% stock engine into the mid 300s without trouble. With some bolt-ons it should be easier to reach 400HP. I guess that the engineer my friend was talking to didn't want to say he whole truth about the engine's strengh, maybe that's just marketing talk? Are you reffering to the Audi's twin turbo V8? It's true that they've been for a while on the market already, but as far as I know they don't have that much technology into them... They're fairly conventional in design in fact. I've read that fuel which is directly injected into the combustion chamber evaporates and considerably cools the chamber, which enabled the BMW engineers to use very high compression pistons for a turbo engine (10:1 as far as I remember). Additionally, more precise amounts of fuel that are distributed by the high pressure injectors mean that the fuel consumption and emissions are lower than in engines with typical non-direct injection. I agree with what you wrote, but from my point of view I can't really tell if what the engineer said was true. Maybe that's because twin turbos have much lower boost threshold? I think it's the same reason why they installed twin turbos on the inline 6 instead of one - it's all about torque delivery, effortless driving, fuel economy and flexibility.

That car would look great on a set of gunmetal five spoke wheels with a fat machined lip. Maybe Centerline Venturas would be good?

This is the most WICKED sound I've EVER hear! BMW inline sixes FTW!!! That's a E46 M3 CSL with a supercharger, some internal mods and a freeflow exhaust... Prox, looks like you won't have to buy a V8 to have such sound.

What you're looking at is the new BMW V8 engine with two turbochargers, direct fuel injection (and no, this is not a diesel engine), and a direct fire ignition system. Now that is car porn! As you can see, the turbochargers are mounted between the cylinder banks, and are controlled by conventional wastegates (contrary to newest Porsche designs, the turbos also have fixed geometry). This position is said to reduce weight because of less piping needed to feed the turbos. To comply with the newest smog standards, the catalytic converters were located just behind the turbos. I'm curious how they are going to deal with the heat insulation - it's not going to be an easy task with two screaming hot turbos lying just below the hood and two downpipes routed just in front of the firewall. The engine is said to be capable of producing 400HP with a crapload of torque. Like the previous twin turbo inline six, the turbos are tuned for smoothness and a flat torque curve rather than all-out high RPM power, like the NA M engines. It will be available in the new X6, and after its release other models (think 5, 6, 7, X5 etc.) will also receive it. There's some bad news, too: an aquaintance of mine spoke to a BMW engineer about the twin turbo six and asked if it had any potential for serious power upgrades, and, sadly, the answer was NO. The reasoning behind this is that the engine is made to handle exactly what it came with from the factory, which means it won't be able to handle much more than 300HP (400HP in case of the new V8). Thankfully, more and more tuners are modifying the twin turbo sixes to power levels upwards of 400HP, so there might be something in these engines after all. But still, in terms of bottom end strength for dollar, nothing beats 2JZs and other motors like that... But please, don't start a typical "what's better" discussion, I think it would be more useful to look what the future of car engine looks like... As always with BMW, it looks promising to me.

Here are some aero-engined cars for contrast: http://www.youtube.com/watch?v=Pi3scFrYgPo The last car was, beleive it or not, built a few years ago by a team of German technicians from the Sinsheim museum. It's a 47-liter BMW V12 aero engine mated to a prewar racecar chassis and a custom body painted flat black. I'm sure that if Darth Vader was to choose a single car to drive around today's roads, he'd definetely take this one...

Frank, you wrote that the SC will be fed by the turbo, which means that the piping will have to be routed to the back of the SC. If so, then how are you planning to route the piping, around the engine or over the valve cover? Another thing is, aren't you afraid that the very hot air compressed by the turbo will break the SC somehow? I've always thought that SCs are vulnerable to hot air for some reason...

Nice writeup, thanks! Do you know how the weight distribution is affected in the S13 after the swap?

To be honest, I don't like the idea of another dash in a Z. Simplicity is the key here - maybe a simple aluminium dash with the S2000 digital gauges would look more suitably in a full-out Toyota-powered racer? It would be much easier to do, too... It's not that I'm against the HybridZ "upgrade-what-you-can" attitude, I just really like the original dash shape, and the classical aluminium dash designs. Give me a wrinkle black painted dash, a set of Smith's gauges, a black leather-clad Moto-Lita steering wheel, a few toggle switches and a pair of black driving gloves, and I'll be in heaven...
