2l bottom end 1.8 digi head.

[Alex Mckenzie]

Hi conversion kings

A little clarification required. I'm looking at replacing my rv 1.8 bottom end with a 2e 2l bottom end ( note it had a auto box previously).

Is it simply a swap of the bottom ends over ? Or is their more to it like changing cam wheels etc.

Tuning!
Oooh and as far as co goes, from what I've read tuning the digifant. Should the co be set to 1.8 % on a 2l, same as it is on the 1.8l ?

And will the flywheel, clutch edit from the 1.8 all fit nicely on the 2e?

I did one on a MK1 GTI years ago and the only drama was the dissy. You needed a spacer ring for it. I think you might be able to use the 2E dissy though as plugs are the same IIRC.

The ECU might be able to cope with the extra airflow and meter the fuel ok that way. Again my experience was with the MK1 and KJet, so not totally relevant to your plans.

Might be a chip available somewhere to better suit the larger capacity.

Digifant should be able use 2E dissy directly. Flywheel, clutch are all the same.

k-jet is a bit difficult that's why I'm still haven't done this

Digi has no problem supplying the extra fuel. I've got a 2e block under a standard 1990 MK2 head with a mild cam. Fuel went from 6.0 litres per 100 k to 6.9 on my daily run to work and if I drive carefully I can get it down to 6.4.

You don't get a big HP increase with the 2.0 block but the extra torque is really nice. Hills that I had to go down to 4th are easily done in 5th now. I still have to add a euro downpipe so there should be even more performance to come.

It's well worth doing the conversion.

The Euro downpipe really allows the 1.8 RV to breathe and spin much better. If you're noticing the HP and trrque increase without it, it must be pretty hectic with it

[Alex Mckenzie]

I have the exhaust of the mk3 installed, is that what your walking about when you say euro down pipe or is that something completely different ?

[Alex Mckenzie]

Sports racer you say you were getting 6.0 per 100k, what co is that set to ?

[benough]

Yep, that's what I'm talking about and I assume he is as well

Digi supply no worries ive even considered keeping it for my MK2 upgrade but im sure Gav will want me to have the MK3 tank and VR pump( custom code doing the tune) so that's what im doing.
