pinto engine work

Recommended Posts

hi guys just need a bit of help here.

i have a 2.0l cortina engine i dont know if its a pinto or not? how am i supposed to tell? ive never worked with one of these engines before. but the plan is to rebuild whatever it is and put it into my escort. its currently ceased because its been sitting around for years. so i thought id bore it out to 30 thou over, get new pistons and rings get the head planed for higher compression, because i want to put a wild cam in it. the head will get ported and polished and valves reseated. what to you guys think? if there is anything i should be aware of could you let me know as i am new to this engine. also if i was to raise the compression to suit a wild cam, how much would i skim off the head?

any help is much appreciated.

thanks team.

Yep Pinto mate dont know too much on the engine castings side of things.

From some of Gaz's posts it looks like planing the head isnt worth it as you dont get much increase compression wise. Pistons are probably your best bet for upping compression.

Otherwise your list sounds bang on man hopefully Gaz will intervene and give you the ins and outs of a pinto :)

Also what cam are you thinking of? A kelford grind? or a kent cams kit?

My old mans got a bare freshly honed block and some decent pistons to fit and crank to match, he would sell it as he has no real use.

He also has some other shit like high pressure and flow oil pump.

Oil hex drives

Prob a head or two, nothing special

If you want the most out of the wild cam then you need to do some port work + induction. Expect to pay at least $1000 on the head for crack testing, skim, new valves + cut, stainless inserts, some porting/clean up, new cam bearings, new oil spray bar (you really want this), & new head studs.

Rough pricing:

$1000 on twin carbs + a tune ontop of that.

$300-1500 on extractors and exhaust

$300ish for Leads, plugs, dizzy rebuild, new coil

$100 for new waterpump

$200 gaskits

$200 seals

$250 new clutch

$100 belts

$200 adjustable cam gear

$??? Labour ontop of this

If you do all this you really want some stuff balenced and a lightened and a dowled flywheel

$500-1000

So if you start looking at it this way then you might start considering an engine swap instead, all depends what you want and how far you want to go. A worked pinto is fun but dont expect anything NA over about 160hp unless paying someone who knows what they are doing to port the head which will cost $1000 alone.

For a muck around car perhaps look at just rebuilding the bottom end, get the head cleaned up and stainless inserts installed, a fr32 or similar fast road cam, extractors and 32/36 standard carb. This wouldn't cost much and would be about 115hp.

oh thanks for the help guys. i couldnt be f--ck-d rebuilding that engine as my budget is way under the prices stated earlier. so i just bought a pinto motor off trademe for $350 its running, so it wont need as much work, im just going to get this new one honed out with new rings, a ported and polished head, wild cam with lifters to suit. its not going to be a high end race machine, but itl still have a bit of grunt. speaking of lifters, can you just buy new ones or do you have to get them specially suited for the cam? also can someone please post a link of the kent cams kit webpage, or somewhere where i can get them in NZ.

cheers liam.

Why dont ya just do a cam on that engine? Dont even open it up or anything... just do a new cam, lifters, and oil spray bar. Put the engine in the car and see what you think. Then go from there. For the engine mentioned earlier the old man prob only wants a couple hundy so you could even start rebuilding another motor whilst you enjoy the TM one you just brought.

Check cam bearings while cam is out although these bearings get way les rpm so usually ok.

Dont go silly with the cam if u want if reliable.

and driveable. Id recomend the FR32 or the next grind up (FR43?) highly for streetable car.... mind you they are the only ones Ive tried.

Jase has prob tried nastier ones.

ok team,my plans are to get this pinto and do a compression test, if it doesnt meet the requirements im going to get it honed out and re-ringed

with maybe a ported and polished head. im then going to slap in a wild cam, something more wild then a street cam but not as outrageous as a full out rally profile. also to go with the cam will be that oilslinger, and new rockers. if all is well and compression is sweet im gona just chuck the cam, rockers and oil slinger in and see what happens.

what you all think?

What are you trying to acheive from the "wild" cam? I am guessing a lumpy idle? If so a FR will get that and be alot more usable than a "wild" cam with no other supporting mods like you suggest above.

I really wild cam will want your engine to rev between 4.5-8k+ and without lightening, balancing and decent flow this will not happen so the cam will be useless.. All you will end up with is a cam with no power down low and not enough flow to utalise the power in the top end.

hi gaz, yeah what im trying to achieve with the wild cam is a lumpy idle, but also want a lil bit more power, with no modification to the compression ratio though, i have no idea what the power gains will be. i had a lumpy cam in a 1300 mk2 escort it went way harder than when it was standard, it had a lumpy idle and all, but i wasnt completely satisfied. and that was a 234 profile race/road special custom ground cam, it was based off a 234 profile but had different lift and duration. soo without mods to the comp. ratio i think a wild cam is best for me, im not concerned about driveability as i dont drive, or live around any serious traffic anyway.

let us know what you think.

imo there's little point in putting a cam in a pinto without porting the head.

I would talk to nismo.capri on here about getting some head work done - he really knows his pinto heads and how to get them flowing. memberlist.php?mode=viewprofile&u=2818

Then I would send PK at Kennelly Cams an email and get him to do a cam for you, there is no better person for it.
