Fiat 2.0 DOHC - the best manifolds
I would like to know if someone makes intake and exhaust manifolds for 2.0 Fiat DOHC engines. Intake manifold for 45 or 48 DCOE Webers and 4-1 exhaust manifold. Can you recommend a good and trusty manufacturer?
best regards
konrad

Re: Fiat 2.0 DOHC - the best manifolds
Can I see a photo of the engine bay of the car you're talking about please?

Hi,
it is Polish Polonez. Unfortunately I don't have any photos now, sorry.

Re: Fiat 2.0 DOHC - the best manifolds
Well, Konrad,
I do ask in guidelines for posting here that folk take time to produce decent photos, and in the case of this question (and many like it) the choice of this_or_that setup depends (often) on the engine bay layout. That's obvious isn't it?
As it happens now I know what the car is I have some pictures of one (owned by Pietr Zalewski). So at least thsoe reading will have an idea what you are talking about here. The type of inlet setup depends how much space there is around the rear carb (as arrowed). This setup has 44IFD Weber, sidedraft DCOE might jsut fit and I have inlet manifolds for both. The IDF need a top mounted distributor or one of the little conversion units that member Mark Allison sells, see: http://www.allisonsautomotive.com
As for exhaust manifold (header) it may be that one of Mark's Fiat Spider ones will fit. I don't sell ex manifolds and generally recommend folk get them made on the car by a reputable specialist of which there are still a few left in the UK. As for Poland I don't know. You should be aware that the design of the header has a material impact on the behaviour and performance of the engine, what is right for one inlet setup and cam type (among other things) may produce very poor results with another. Or it may be fine.
I have written extensively about header design in my new book, I don't want to even begin to reproduce it here.

Re: Fiat 2.0 DOHC - the best manifolds
Thank you very much and sorry for not being precisely. The problem is that I've needed the quick recommendation for my friend in Hungary who will build such an engine for hill climbing I guess. He asked me to find the photos of 2,0 DOHC in Polonez with DCOE carburettors, but I had a big problem with this because there are mainly photos of Peter Zalewski car with IDF, as you have mentioned. My friend haven't seen the car in which this engine will be, and me neither, so this is even harder to do when you don't have a car and you can't measure anything, that's why i'm asking people who can know anything for help, because he has to make decisions quickly what do do with this. There won't be a brake servo mechanism in this car so I think it would be able to put 48 DCOE with quite short trumpets and short manifold.
You've written that you have inlet manifolds, can you please send me an offer to my email: [url]mailto:konrad@ladasport.pl[/url] ?

Re: Fiat 2.0 DOHC - the best manifolds
OK - with no brake booster you can use my M131 design. Clears a distributor mounted on the block and almost zero flow loss.
That is a proven GC design. You need 45s definitely NOT 48s! You won'tget any torque at all on 48s on that motor.
Price is on P2, manifold £210, fitting kit £54 plus 17.5% vat and shipping on UPS that will no doubt be about £65 + vat (again). Too heavy for mail. Sorry, can't help that there's VAT to pay.
I have stock. Shipping within 5 working days of payment. Same as the one in the photo.

Hi Guy, Hi Konrad
Here is a picture of my Polonez engine bay. Carbs are 45 DCOE, brake booster is removed and standard brake pump is used (as in Piotr's car), air filter is ITG one piece, shallow version. Ram pipes are 25 mm long as far as I remember.

What's the inlet manifold Slawo? I can't see in that (nice) photo.

It's Fiat Ritmo 130TC, but I replaced steel-rubber "sandwiches" with aluminum pieces, machined according to my drawing. I also enlarged a little manifold ports, to work properly with 45 DCOE's.

Re: Fiat 2.0 DOHC - the best manifolds
I have a good used one of those 130TC manifolds - no use to me - if you fancy making another set of adapters I will send it at mailing cost only, if it gets another enthusiast going..
