1.9 Mi16 Running 1.9 Loom

[Peetypug 5]

I'm buying a 205 with a 1.9 mi fitted.

It's running on the 1.9 gti loom with the dizzy convertor.

Would it run on the 2.0 ltr loom, eg coil packs 3 row ecu etc etc

 

thanks in advance

should run fairly well especially compared to the 8 valve stuff, from memory you'd need to fit the 2.0 Inlet cam (for the cam phase tang), thermostat housing (as it has the cam phase sensor in the top of it) and cam cover (to accept the coil packs)

 

knock sensor if it hasn't got one, and a proper TPS onto the Mi16 throttle body rather than the throttle Switch they use (or a gti6 inlet)

 

not sure how different the injectors are though, worth checking out.

Also need to drill and oil drain hole in the side of the head to use the s16 stat housing.

Given that it's MAP based, I wouldn't expect the XU10J4 management to adapt the fuelling to suit a smaller XU9J4 engine very well. Probably won't be a million miles off, but between the capacity difference and the different inlet manifold characteristics, it certainly won't be "right"

 

Given that 1.9 Mi16 management isn't difficult or particularly expensive to get hold of, I'd just source some and use that instead personally.

The other way round (1.9 Mi16 management on a 2.0 Mi16) works excellently but that adaptability may well be due to the fact it uses an AFM, as Anthony says the MAP based 2.0 management might not be as flexible.

thanks guys

will buy a loom and ecu when i get chance

dont go through the hairpulling exercise of a wiring conversions (IMO) Proper mappable ECU with a proper new loom thankyou please

Hairpulling? Its half a dozen wires maximum to get either a 2l or 1.9 MI loom installed and the engine running. Done many before?

the hairpulling is where someone else has done it, there's a problem, and you haven't a clue what or why they've done what to it

This is true i guess. I just try to avoid all splicing of looms, especially old ones

Tbh its not too bad as long as you are sensible. If a plug looks like its on its last legs its usually best to crimp a new one on/run some fresh wires. But at least everything plugs straight in and will run first turn of the key.

If you where going to retro fit anything I'd give the GTi6 ECU ago, I know the cam sensor would be a pain but at least you can re-map it with ease
