which bottom end for 2.0l conversion and do i go for it?

[dTEA]

Alright all, my MOT is through and that means the old gal is gonna get taxed and tweaked.  I reckon after a trip to Awesome they are gonna tell me to bin the 1.8 bottom end and start again, although i might be proved wrong as I know it needs a good tune anyway, but at the min she is running lumpy (part due to a top up of ordinary unleaded rather than super) and is down on power.

BUT, i've been offered a bottom end out of a 94 mk3 8v.  Does this bottom end have any complications when swapping just the block over retaining my 16v head and ancillaries?  Are there any other parts off the mk3 I would need?  Reckon the guy is gonna be cool with a decent price, but I'm after getting my old girl up to standard as I wanna get rid of my civic but i'm used to the raw power that 200bhp gives.

Comments etc engine codes etc welcome

You cant use the 8v block on a 16v (well you can but its heavily involved and more suited to turbo conversions)

Just put an ABF in there, with some proper management.

You and those ABF's  I think dTea wants a bit more power/torque without having to change the engine completely.

[Diamond Hell]

Have you had the ABF experience?

It's very persuasive, from the way it starts and idles like a kitten, to the way it just keeps asking you to spank it harder and more and more like a whore on a quiet night past 6k RPM

Should have a dyno plot off DannyP's after next Friday - will be interesting.

Not yet 

I do like you description though

A 9A engine with your KR cams should see you knocking on the door of 150bhp and is a direct swap for your 1.8 engine as it's on a K-Jet set up in the Passat and Corrado.

Cheers Nick, its a DIY thing that I was looking for as I want to get specialist work done on the bodywork, and possibly a 288mm brake set up.  The coilovers, bushes etc I'll want to do myself and the ABF swap looks a little too time consuming.  So a 9A lump it is then

If was swapping the whole thing, why not just 1.8T it and get some where around the 230-40 mark out of it?  But then that means new gearbox and a lot more messing with clutches and a lot more expense....unless anyone on here wants to loan me it, cos i sure as hell cant fund that myself

the 9a and abf conversions are identical, the only problem with using an abf is if you want to fit a 4 branch you have to modify the rear engine mount so the engine sits lower, but the abf is slightly better.

oh and cut the rib out of your bonnet for the abf as well cos its taller
