as all youngins wanna do, quite stupidly, is have a stupidly fast car. and ive been thinking about it quite seriously as i have a motor to play with. and have been reading up on as many projects and books as i can get my eyes upon.
 
for thought regards to making big power, should any plans be started with trying to get more displacement?

Yeah, 100thou/1mm over is a good start.
Zero the deck on the block.

Hold your breath when you buy gp1 o/s valves.

disclaimer: im going to make an idiot of myself on this post because most books and such barely touch or dont provide what i consider to be enough info regarding some things (mostly because of changes in laws in the past 30 odd years. ) ideally this motor will go in a MK2, dont have the car yet. please by all means point me to someone who can answer this sorta stuff with some sort of acuracy
 
stroking is not worth the coin as far as i can gather.
how big of a bore is too big?
as much as it pains me to say it, i presume straight lpg is a good solution for its high compression tolerance and future stringent emission standards?
on the other hand if i wanted to go petrol, would that be a big hurdle? or am i looking at a couple of cats and such?
 
 
(just to head off the conversion questions, i want it ford powered, legal, non efi. i already have a pinto and if it melts at the end of this, then i would have learnt alot :D )
 

Firstly find yourself a shell that was made before 6/76. That way you avoid having to comply with adr27a and can fit twin sidedrafts. Second there are a few engine builders on here. Wozzah and Mk1Lotus to name two. Send them a PM and go from there.
 

i agree start with an early mk2 or mk1 and then you arent limited by emission rules.give yourself options and you will save money in the long run.take it from someone who has spent his life taking twin webers and refitting emission gear to escorts after a defect notice

i guess the benefit of not already having the car is if i dont get the motor under emissions regulations i can always buy the model that helps most :)

 
If you are going to try and get big power from a Pinto forget about trying to accommodate emissions regulations. It wont happen .... Unless you go EFI

not even with cleaner burning fuels? aka ethanol or lpg?
 
they guys at a lpg conversion place i visited were pretty vague about it, but its marketed as a much cleaner fuel..

LPG is NOT a cleaner burnign fuel - Older cars with though are exempted from complying with emmision controls though :)
 
It has a lower BTU value, so therefore the fuel economy gets worse (by about 30%), but at a third the price per litre, it cost about 50% of petrol.....
 
From the little I know, only post 2004 models on LPG have emmision control requirements. (I had a choice of single or multipoint injection systems with my 2003 BA Falcon wagon, and my RS2000 is on Gas Research carby)...
 
Unless going turbo LPG or injected or even liquad injected, you are not going to gain any power over a tuned standard petrol model.  My RS is great on $$$ (try $30 for 450km around town), but even with a gas cam and properly setup, has less power than a nicely tuned standard Pinto....

theres no power gained using either fuel type. Difference being the dynamic compression ratio that either fuel will accept. Decompress the engine for petrol or dont for lpg and get the same power.

would it burn cleaner when used at same efficiency rate?

Also, if used in draw thru, would the impellers suffer any damage due to the -40 deg intake.
