sholdowa Posted May 23, 2008 Share Posted May 23, 2008 I'm starting to look at getting bits together to build up my pinto, and just looking at the cost of good quality pistons, let alone getting them from the uk is scary. What locally available stuff can go in there as an alternative. I'm happy to pay for machining (especially if I can keep it local/cash! ), and want to increase the capacity as far as poss without going silly money. I'm keeping it na, so want to keep the piston tops approx at the top of the ( 205 ) block - with the longest rods possible. Is there anywhere I can look this kind of stuff up on the net, or a local guru about??? Quote Link to comment Share on other sites More sharing options...
Gaz Posted May 23, 2008 Share Posted May 23, 2008 Buy this and save yourself HEAPS of $$$$ http://www.trademe.co.nz/Browse/Listing ... =156657713 Will do 200hp with 45's a Vizzard head tickle and the right tune. Quote Link to comment Share on other sites More sharing options...
crazy_rich Posted May 23, 2008 Share Posted May 23, 2008 yo, Shane at my old work knows quite a bit about these engines, he'd be worth having a chat to. He's been racing one in classics quite successfully for a few years now though hes just lunched the crank. Hes got all the engine machining gear in his shed at home too, so he's cheap labour if he's got the time. M S Coombes Ltd 344 St Asaph St. Tell him Rich sent ya. Edit, or do what gaz said.

Fuck, that's sweet Quote Link to comment Share on other sites More sharing options...
Gaz Posted May 23, 2008 Share Posted May 23, 2008 Guess that also depends on what comp ratio he has planned the head to run and if the petrol here plus pistons will keep up with the high comp... if it is high comp that is. Quote Link to comment Share on other sites More sharing options...

Gaz Posted May 23, 2008 Share Posted May 23, 2008 good quality pistons, Also, what do you call good quality? You want forged? Ive run new ACL pistons in mine both times and never had any probs with them. First set at 90tho over cost me $200 Second and current set at 60tho cost me $95 A set went on trademe last week for $90, forget what size over. Id say those pistons if the tune wasnt all up the piss would get you 150hp easy as. Thats a realativly worked street pinto with ported head and 40's or 45's. What are you aiming to build power wise?

Vai-Man Posted May 24, 2008 Share Posted May 24, 2008 You could try and run 2.8/2.9 colonge pistons and diesl/fiesta rods but it requires machineing and i dont know the avalability of those parts over here. takes it out to 2.1 though Quote Link to comment Share on other sites More sharing options...
Testament Posted May 24, 2008 Share Posted May 24, 2008 do you know the following: -current bore size -maximum possible bore size -deck height (from crank centreline) -stroke -big end journal size -big end journal width (or standard rod bearing width) -standard rod length centre to centre -standard piston compression height -standard gudgeon pin size -Combustion chamber volume also do you know if the factory cranks have any special heat treatment e.g. nitriding?

sholdowa Posted May 24, 2008 Author Share Posted May 24, 2008 I'll borrow a micrometer, and get all that back to you. Mind you, it may be worth taking a punt with that motor in Gizzy. Any locals want to have a look for me?? Beer money provided. Quote Link to comment Share on other sites More sharing options...
d.p.n.s Posted May 24, 2008 Share Posted May 24, 2008 shit yeh you cant go wrong for $700. Quote Link to comment Share on other sites More sharing options...
Spencer Posted May 24, 2008 Share Posted May 24, 2008 you must have to spin a pinto pretty high to hit 100hp/L? Quote Link to comment Share on other sites More sharing options...
RUNAMUCK Posted May 24, 2008 Share Posted May 24, 2008 If you want forgies, Denco engineering in CHCH can machine up some ross blanks for you. Forgies cost though unfortunately. Otherwise I'd have some in my A15. Quote Link to comment Share on other sites More sharing options...
Testament Posted May 24, 2008 Share Posted May 24, 2008 <100hp/L - bored out to 2.2L But still probably need revs >7500 Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted May 24, 2008 Share Posted May 24, 2008 a cam regrind using a factory cam on a pinto is usually pointless. reducing the base circle fucks the job. ask him what the bore is on that motor. 200hp will need a fair bit ov work tho.

Gaz Posted May 24, 2008 Share Posted May 24, 2008 Yup he seems lil vauge, I asked him cam specs last week and he could'nt tell me. I do still think that for $700 you cant go wrong even if you ran it as is with 40's or 45's youd make some decent power and torque. $700 for rebuilt engine with modified internals, a cam and larger valves is a steal IMO.

Testament Posted May 24, 2008 Share Posted May 24, 2008 Fair enough. Probably by far best idea if you just want a good engine to roll with Quote Link to comment Share on other sites More sharing options...
Gaz Posted May 24, 2008 Share Posted May 24, 2008 Just membered he offered it to me for $650 after auction closed.. so can be had for cheaper than $700. Quote Link to comment Share on other sites More sharing options...
eke_zetec_RWD Posted May 24, 2008 Share Posted May 24, 2008 assuming all modifications have been done correctly yea should be sweet. check if they are flat top pistons Quote Link to comment Share on other sites More sharing options...
