Overall engine height may be a problem, as BMW run their engines canted (leaning over to one side) to enable lower bonnet lines.

I know that many blokes in the US shoehorn 6 cylinder BMW engines into the smaller chassis for a pretty potent result. Try searching here: http://forums.bimmerforums.com/forum/index.php

Having said all that, run a tape measure over things. An RB might just fit with no real dramas - as far as engine conversions go. :laugh:

id think that most things external to the engine will need to be modded, you might need to make a plenum that sits closer to the engine and make a custom exaust manifold for the car.

who knows ive never done it before :laugh:

i've got a rb20 in my e36 at the moment, just bought an rb25 to build up and put in it, rb30 would have been nice too but a little outa my price range.

some things to consider when putting rb motor in e36:

- convert sump to rear sump, i went with a new custom sump to clear the bmw crossmember

- custom single piece tailshaft (hardy spicer for around 220)

- definately upgrade diff for rb30 (M3, i've heard someone running 528i diff in theirs)

- remove ABS unit because i found the dump pipe sat right on it, i reran all the brake lines to tidy it up

- for using the tacho from the 4 cyl, no problem, just get one of those 'jaycar speedo signal converter' kits.. works great on my setup.

- oh, and buy one of those haynes manuals! best asset i own

I loved the idea of using rice in the beema.. its still going strong, the most reliable car i've ever owned..

Here is the official build thread that my mate maintains (he did the fab work).

I've since wire-tucked everything and repainted the engine bay.. looks heaps better than before.

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
