Go somthing really retro man ! Like a 1967 HR Holden. They only weigh about a 1000kgs, got heaps of space under the bonnet, plenty of wheel arch space(295s with eez). Nobody looks twice at one at the lights but when you nail it with the RB25 your gone !

how about a PRB? rip-off from a lotus 7. weighs a measly 400-odd. stuff a rb25 in, goes like the clappers. ive been in a prb with the 110kw corolla engine, 0-100km in 3.9 and covering the 1/4 in sub 14. very quic, but it would be a real hassle to fit in a 6 with a turbo, plus you scarafice a few comforts like air con, abs, a bone jarring ride. but hey, when it comes to brawn performance that you want, those things dont matter :)

Yeah that'd be fun, they already do twin Hayabusa motors into something similar - it's called the Tiger Z100WR. It's 4WD too, and does 0-100 in under 3 sec, and all the hot-up bits for Busas will bolt on... including the turbo kits :)

I still reckon for 3 series beemer if you want something reasonably modern that'll handle nicely and allow you to retain aircon etc. It's been done plenty of times, and the results are, from what I hear, not too shabby.

It's been done a number of times. A mate was looking at doing this to his E36 320i, but he sold it instead.

There doesn't seem to be much info on the net, but from what I understand the motor itself pretty much just drops in there. Obviously you need to fabricate engine mounts and may have problems with sump vs crossmember, but it will fit. I believe you have to go for thermos as there's not quite enough space for the stock engine fan, and may have to get a bit creative with your intercooler piping. Wire up an ECU to run the motor, and let the factory BMW computer in the car run anything that the engine computer can't (dash, climate control, whatever, just guessing here). I'm lead to believe it's a reasonably simple swap.

German Car Club of Victoria - flick through that thread for some discussion on your options. Check out the photo a couple of posts down! :drooling:

    • There are a few different ways of doing it. I'm currently running two 1000cc pre-TB nozzles and PWM the pump for control. I'll be moving over to a constant pressure system and direct port. I'll run the pump off a regular relay, have it cycle on roughly 5psi before I start injecting to build pressure and then PWM a WMI solenoid (It's basically an injector that can take a lot of pressure and not corrode with water and meth.) The solenoid feeds the 6 direct port ~200cc nozzles. I'll also keep one ~250cc pre-TB nozzle to help keep IAT's in check.  Safety will be a little different as well. I used to use a pressure switch but will be moving over to a pressure sensor between my solenoid and nozzles. I'll trigger my solenoid and if I don't see specific pressure within a specific timeframe (e.g 100psi within a second, 175psi within 2 seconds), I kill it and revert back to non WMI maps the same way I did it before with 4D in Haltech. I was just figuring out the timers in my ecu last night. They made that a little more complicated than I would have liked... I wish Haltech offered a larger set of logic/math functions like other ecu's do. I can't do very much with just AND's and OR's.  I've been asked to do fuel/ignition mapping on a medium bore engine at work in May (192L V16). Being the only programmer in my region and having went and opened my mouth about knowing the ins and outs of fuel/ignition mapping, I have now been deemed an expert. Fun fun. The entirety of the logic and algorithms are programmed in C on a PLC. As I spend more time figuring it all out, I like what I see and eventually I may consider doing the same as a pet project to replace my ecu.   
    • This would be interesting, would you feed it via a 2nd row of injectors? Or just usual WMI nozzles?
    • Cut sump up and extend. Win win 😂 
    • All, What's the recommended torque for the 1/2 head studs for RB30 twin cam conversion with RB26 head?  
    • also, we need to know which solution worked....
