B200EA (with EGR and Pulsair) to B200F conversion

[trabitom99]

Not something that's been done very often I'm sure, as my problem is unique to Germany (for the moment anyway).

How hard would it be to convert a B200EA (with EGR and Pulsair) to a B200F? The reason is: Euro 1 emission levels, thus meaning 200 Euros a year savings in tax and a "green window sticker" so I'm allowed to drive into towns.

As far as I know, the following parts are different:

Renix
ECU
exhaust manifold with lambda sond
shorter downpipe
3 way cat
air mass meter

The B200EA has PulsAir and EGR thingamyjigs which would be thrown out / blanked off. Both have the carbon filter AFAIK.

Has anyone done the conversion? What would be the easiest way, swap the engine clean over, or just the bolt-on parts?

Cheers

Whats the insurance like for you to do an engine swap bud? I'd prefer to do the swap, even if you kept your B200EA. If not, you want to green book up the values for cam and compression ratio, the Renix swap must be for a reason, sparks shouldn't change without a cam change I'd have thought.

FWIW, if I was going to do this (and this is only a quick set of thoughts that pop up rather than comprehensive thinkings based on when I was thinking of LH-ing a UK 360) Germany wants emissions specs only. So, that should be fuel side only. In theory, just pulling out LE Jet, the loom and the injectors (may well be a different spec for the F ECU, I don't know what ECU it is but worth a check)and replacing them with x Jet, loom, injectors if needed and the lambda (welded into the old exhaust pipe even) may well be enough.

Ooooh, actually, while I think, check the trigger pattern too, as it might be a different flywheel (inwhich case it's engine out anyway...)

Renix is the same, 411 curve. only thing i'm not sure of is the C-plug on the renix, you'll have to copy the wires that are connected to ground on a original V300 with B200F engine.
if your 360 has a 3-way cat allready, i'd simply weld on a bung or swap the manifold over.
keep the loom, just find out where the lambda sond connects to the ECU and replace it with a B200F's ecu.

for more specific info, you could send François on the V3C forum a PM, he has both B200EA and B200F models sitting in his yard and knows quite a thing or 2 about the engines.

OK, thanks for the info!

I've flicked through the parts catalogue - the engine head and cam seem to be the same on all B200s. B200 E/F Renixes are the same from CH 241000 onwards. Injectors are the same, flywheel too. The differences I could find are:

wiring harness injection system (maybe due to the lambda sond?)
air mass meter
ECU (injectors are all the same)
different clips for the carbon filter (EAs have them too, E's don't)
no Pulsair pipes (would need to be blanked off on the B200F cylinder head)
different intake manifold "shutter housing" on EGR / Pulsair cars
exhaust manifold (for Lambda sond)
catalyst

@Chris - I haven't checked, but I'm sure insurance would be no problem. I asked the TÜV guys ("gods" of motoring) and they have no problem either as long as the car was once sold with a 3-way cat. So - engine swap from similar MY to improve emissions - no problem (as long as the emissions are OK.) Even a future historic plate would be OK.

B230 conversions (even with a Euro 2 emission rating) would be much more difficult to "officialize".

@Anjo - thanks for the heads-up - I'll send Francois a PM.

Why am I asking? I need a fall-back in case the welding on the 360 daily proves too much.
