P100 Pinto Engine
DavidW - 23/6/08 at 02:41 PM

Hi

I have the option to acquire for a reasonable price a low mileage 205 block pinto engine from a P100 pickup.

I was hoping I could drop this in place of the naff 1600 engine in my part built Indy without any major work as I want to be on the road this year.

The problem is that a quick search reveals these engines are low compression versions.

How much of an issue is this, do I need to keep looking for engine?

Many thanks.

David

Low compression type - just stick a turbo on it then - problem solved!!

here you go

could you not get the head skimmed to raise the ratio?

you'd need skim the block to get the CR high enough (I think, I'm not an expert on the LC engines)

it'll much easier to swap the pistons to HC ones (I think they are the only difference, but I'm not 100% sure)

My memory may be playing tricks on me, so I may be wrong, but I'm pretty sure in the dim and distant past I was told by someone in the stock car racing scene that fitting the head from a 1600 pinto will increase the CR on a LC engine?

Thanks for responses.

The link to the engine for sale would be great apart from I need stop spending for a bit - this engine is close by and will only cost me £100.

The 1600 head idea would be good as I have reconditioned head from a 165 block Pinto. It can't be that easy, surely?

I assume if I replaced the pistons, the block would need machining and I may as well start afresh?

Yep head trick does work, Ideally the head to use is the 1.6GT head as that has 2.0 Valves AND Cam as standard. If swapped with a head from normal compression ratio 2.0 engine, it taskes the CR ratio from 9:1 up to about 11/11.5:1.

Ooh, so the 165 head would still work?

Any downsides? should I stick with the 1600 cam?

Thanks!
