1800 Pinto + 1600i Head

[Guest Takumi]

Good new to all those with 1800 pintos ..

I have been looking into replacing my 1800 leaded pinto head with a unleaded one..

Have discovered that the 1.6i pinto head fits the 1.8 bores ( only 0.5m in radius different) the difference in bore size is next to nothing, and would advise to use the original 1800 head gasket to fire seal the bore.

 

The 1.6i head has smaller combustion chambers! giving a compression ratio on the 1800 block of 10.3-10.7:1 depending on what vehicle the 1.6i was from.

Has anyone else looked at this before. . .seems a good move, gettinga higher CR ( not to high for quality unleaded) and also the benefit of unleaded seats. !!!

 

Post a reply if anyone has heard of this, or has a similar combination in use..

1600 heads are quite often used as the basis for higher compression 2l engines as it's better to open the chambers quite a lot than to have to skim loads off a head with bigger chamber to start with. The 1600 head can conceivably be used on a 2l block straight away but I beleive the compression ratio will be way too high. In theory your swap should be fine as 10-1ish is a good compression ratio without putting too much stress on other things. I wasn't aware that Ford had injected anything other than the 2.0 Pintos though.

Yea, Ive read that in Vizards book.

 

Im just looking out for 1.6i engine/car . .

 

Ive spent a few minutes today in a lecture alculating all the chamber sizes of the 1.8 , 1.8 & 2.0 engines and the various combinations you can use and what CR they give..

 

1.6 head ona 2.0 block gives about 11.7+ :1 a bit much for std unleaded

1.6 head ona 1.8 block gives about 10.3-7 :1 just right for me . .

2.0 head ona 1.6 block gives about 8.2:1 - - good for a high output turbo engine.

Tak, What happened to the all singing, all dancing Pinto engine that you'd built?

You know the one, that one that was on E-bay for sale.

[Guest Takumi]

Hi,

I had it on ebay, but the winner guzumpt me, user caller Mark

 

later was re-advertised, but then attracted no-genuine bids.

 

The engine had also been advertised on www.fastroadandtrack.com @ £325

 

and yesturday (!) I recieved an email from a guy who saw it on the www.fastroadandtrack.com , and is genuinely interested and is travelling up to buy it on sunday 22/04, we negotiated on the advertised 325 price, and we settled on 275, a bargain ( more £ in parts) . . ., I just hope he does turn up.

 

The engine is going into a Ford Escort RS2000 Track day car. !

- pleased its going to a good home..

 

I need to sell it due to financial issues, but am hoping that I will beable to build another pinto engine maybe over the summer. I would like to build a 1.6i Turbo engine with a 1.8 Head to give a 8.3:1 CR to enable to handle high boost pressure...

 

watch this space.
