Re: M54 swap into Shark?

I searched the forum for info but nobody's done a write-up here. We are looking into swapping an M54B30 into our E12-based E24. We have a donor car--a 2003 530i, 5-speed. But we also have an opportunity to buy a ZHP for the swap. You may recall that we bought the E24 for $500 and have been racing i...

Re: Video/Audio of stock M30 motor at Idle?

I removed the polution stuff from my 530i as that was apparently responsible for the cyl head cracking issues. Did only the Euro E12's have the 9.0:1 comp ratio? Do you think your car would perform better or basically the same with the fuel injection? :?: All the Euro M30 2.8L motors had 9.0:1, unt...

Re: Video/Audio of stock M30 motor at Idle?

Nice ride. Makes me miss my 5 speed. Current E12 is an Auto. I think i do need to adjust my valves. Is that a stock exhaust set up? Yes, apart from the downpipes it is stock. Of course, this car has no pollution controls at all, and a 9.0:1 comp ratio. Like most Euro e12s of the time, except the ea...

Re: 76 530i AT Idle issue?

The odd thing is that the idle was fine until I put in a new dist cap because the old one had a lot of carbon on the copper transfer points. I thought a new cap would improve things but maybe the last person to set the idle did so with the bad dist cap? There is an adjuster for the idle speed. Try ...

Re: Automatic Transmissions?

In any event the Getrag 265 5 speed is the best gearbox for an E12. More fun to drive and better gas mileage. IMHO :) I know a lot of people get bugged by the highway cruising, but the old Getrag 262 4 speed was nice. The earlier ZF (it had BW synchronizers) 4 speed had a lighter feel, but the 2nd ...

Re: Automatic Transmissions?

Karl, In my experience throughout the years and various generations of bimmers (E12, E28, E34, E38, E46, E53), I have tried to avoid ZF as much as possible. They seem to enjoy "complicating" parts that have no business being complicated. I have dug through ZF and GM transmissions from my various bi...

Re: Automatic Transmissions?

I'm repairing a new to me 77 530i. Is there an easy way to tell if the automatic is a ZF or Borg Warner...markings? Was one considered more trouble free than the other? Easiest way to tell is the shifter stick, the BW-65 has an old school T-bar handle, the ZF 3HP22 has a rounded handle, like the ye...

Excellent Eric. 8) And I like your red pinstripe on the black paintwork. Pinstriping used to be so fashionable on cars.

Thanks Mike, I always wondered how those cars worked, since the rest of the range had L-jet. :)

Re: 1980-83 e21 320i, oxygen sensor question

The O2 sensor produces an electrical signal, so it has to be processed somehow. This article mentions a controller of some kind that modulates fuel pressure through a valve that appears to be especially for K-Jet with lambda control : http://cleanflametrap.com/kjetControlller.htm I don't know much ...

1980-83 e21 320i, oxygen sensor question

The 1980-83 e21 320i had the 3 way cat and oxygen sensor, but how did they do that with K-jet? How did they keep the fuel/air ratio at the 14.7:1 level precisely, when the fuel injection didn't have a computer :?:

Re: Coolant in oil

If you get lucky you might find an early, possibly Euro, block for a very reasonable price. An easy swap in for a very noticeable improvement in performance.
