how to modify and tune a 2,0l ohc engine

[Jimmy]

Does anyone know how to modify the 2,0l "pinto" ohc engine? that would be NA tuned, not turbo or Nitrus oxcide tuned.

Because I'm tuning my ohc engine, and i wonder if anyone has some other great tricks to go with this engine?

current modds beeing done, rebored to 2,74l that would be 4 mahle forged pistons of 91,93mm, planned deck, lightned rods and balaced cranck, O-ringed block, so the pel-pro gasket will take more than 160 bhp, the top is the 8 valve standard ohc, wich will have the kent rl 31 rally cam, adjutible vernier pully, ported inntake and exhaust ports, and i'm putting on the rally exhaust manifold 4-2-1 type with 2,5" end, and 2,5" freeflow exhaust. The intake is a Hi-flow intake with 2 x 45 dual webers with pipercross filters, hi-flow facet fuel pump, Empi Oil cooler.

when i get the engine put together, i'm going to get it tuned on a rolling road, I'll post the dyno figures.

You could also snag a turbo setup from a early 80's Mercury Capri. The engine was a 2.3 liter 4 cyl. I'm pretty certian the block is the same. If it isn't. just yank the whole engine complete with turbo. It should drop right in.

The pinto's respond better to Turboing than anything else.

The most hp you can expect from one N/A is about 180-190. and thats with a fair degree of tuning.
Thier not really Fords greatest acievement in terms of engine design.


For simple bolt ons a set of side draft webbers and proper Header will make quite a noticable differnce.

But to really make the most of it you need to think about taking the head off and getting it proffesinaly ported, and finding a suitable cam to match.
