So the head was well and truely shot, gasket failure and severely pitted head. So on went the 2.0 (1.8) ltr head I've had sitting around...it deffo not running 100% but already I can feel a bit more urgency from the engine and sounds very different too. I guess I need a remap to get it running spot on so can anyone offer garages in Hampshire (southampton) who can do the work.....oh bottom end was fine, no damage which was a result...

You using the 2.0ltr inlet manifold as well?? Exhaust ports any different and if so are you using 2.0ltr exhaust manifold as well??

As for remap, maybe try these guys: http://www.reddotracing.co.uk/rollingroad/default.asp

They've got Alfa/Fiat experience so might be worth a try??

My 145 Turbo is getting mapped by http://www.fcperformance.co.uk/ when it's done, not sure if they deal with the Bosch ECUs on Alfas but they've got a very good reputation in Fiat Coupe land.

The ECU's as you know on the Coupe are EPROM...as are the early 145's. So the mapping factor will be the same.

when i did mine i put a 2ltr maff in. it helped a lot
i think a remap will help as making it run a lot better on petrol and that's all blush.gif no3.gif

Its seems to have settled down a bit having driven the thing for a few miles, still not right so remap i think is the way to go. Having chatted with the mechanic who fitted the head, said it's not from a 2 ltr, probably a 1.8.......it's essential the same head, same cam but doesn't have the trick inlet "best of both worlds" he said...I'm sure I was told it came from a 2 ltr...anyway used all teh stuff currently on my car including the exhaust manifolds...had the throttle body and inlet already attached which my mechanic used....found a couple ofplases in southampton, none specialise in alfa's to do the remap, 250 seems to be the going rate...but at least i got my car back!!

Hate to say it but wouldn't it be cheaper / easier just to get the right head?! unsure.gif It's also much more likely to work properly.

Have your tried AHM ? Adie specialises in alfas but suspect it may cost more than the right head would. From memory he's based a little way up the M3.

Is there any info on the camshaft swap i.e 1.6 engine with 2.0 camshafts? Sounds interesting.

yes i have 2.0L cams in my 1.6L

it was done a while ago now.... pick up seemed better but you will need a remap to get the full benefit

so discovered part of the poor running issue, the exhaust wasn't sealed properly at the front pipe, no wonder it was sounding bad...as it heated up it would gradually seal itself but when cold it was blowing..now sorted that little gem out things sem to be a bit better.. noticed it still sounds harder edged which i like and pickup over about 3500-4000 rpm has improved a lot, remap still needed to make the most of it... KIRK46 did you find yours was a little flat high in the rev range in 3rd/4th, suspect too much air and not enough fuel which again would be sorted by a remap..there are a few places round here that do chip replacement but need a rolling road to sort the set up...like it though...

Hey Black 146 hows things?

I think it's using the standard injectors that come with the 1.8 (discovered it was a 1.8) and inlet manifold too, using my existing exhaust manifold from the 1.6 system. With my 1.6 it would race for the redline in 3rd and for the best part in 4th but seems to get to about 5500 - 6000 rpm and starts choking, probably would get to 7000 rpm but feel it would take an eternity...also running K&N cone so I imagine too much air in the mixture ..

still ruining her IN witch is really hard as she is so fast on pull away and a over heating problem as it comes with a new head gasket joby
when i put my 2ltr head on i did have a maff problem so i put a 2ltr one on and she did run a lot better but i don't if that's down to it being new or a 2ltr ?

I would have thought that the MAF's are fitted with different resistors to cope with the amount of air flow passing over the wire.

So worth changing the MAF then which may help with the running?

I'm no expert but isn't the MAF just there to monitor the air flow, tell the ECU what is happening and the ECU then modifies the fuel mixture.. Would it really make any difference as so far the MAF's i've looked at are for 1.6, 1.8 or 2.0.. There is nothing wrong with my MAF its relatively new. Just a thought really..
