Pinto tuning tips - Dellorto 45's

[gallen (bph)]

I've got a bog standard 2.0 Pinto engine / 4spd box. They've covered 39,000 miles.

I've bought a set of matching Dellorto 45's that are currently on an undisclosed downdraft manifold. The carbs have been sitting for a while and so I am going to get them re-built with the correct service kit.

I need to know the best way to go forward and get more power from my engine, and if the twin 45's are the best way forward.

I will obviously source the correct inlet Manifold for the Carbs - will the DCOE manifold fit, and are the 40 and 45 manifolds different?

I am planning a 4 into 1 exhaust manifold / possibly a Cam change if benefitial.

The car will be for road use. I need advice on the correct jets/chokes (36mm at present I beleive), plus a good cam to complement the carbs
(fast road use - so MOT emmissions are a consideration!).

Will I benefit from updating the ignition system?? (if so, which!) Is anybody be able to recommend a decent 4 branch exhaust?

What would be a reasonable power output/gain to expect from the above?

I have also heard that by skimming the head and fitting standard 2.8i pistons increases compression ratio and capacity to 2090cc - would this be worth doing, and if so, what implications would arise?

I need to add that I can't spending thousands in one go, so I need to make sure things are done in the right order.

I don't know if it will help you, but I have a copy of a PDF book regarding "Powertuning SOHC Pinto Engines"

I haven't read it thoroughly yet, but it shows the weak spots on the standard Pinto engines and how/where things can be improved regarding porting etc

Let me know if you want it... it's a 35mb file, I could bung it on our server somewhere

Come to think about it.... I think I've got a spare pinto ported inlet manifold sitting around in the shed to take 45's we could come to some arrangement if you need one

both sound cool!

-Please let me know the details, and I'll download it!

thanks a lot,

Geri.

I've got a mate who bought a Fisher Fury and threw the rebuilt 2L pinto out of it (complete with special gearbox), I don't know what the spec was but before it was rebuilt, it was used in a Mk1 hillclimb Escort. It has a lumpy cam and some tricks, currently running EFI. It's sat under his workbench as the Fisher has now got a Fireblade engine. He's up for selling it, not sure about the price. PM me and I can whang you his email/mofono
