75mm piston displacement on a 4efte?

[kirky1]

getting a forged engine and just wondering how much xtra cc i will be getting? boodas

if u mean would it increase from a 1.3 when u bore out from 74mm to 75mm then no i wouldn't bother your arse worrying,
also y you goin 75mm is it already bored to 74.5mm

74.5mm makes the block 1349cc

and 75mm is 1367cc

i would be quite worried about the thickness of there bores at 75mm. there is only 3.5mm between the cylinders as it is on the stock bore. you will be getting dangerously close to the coolant gallery's at 75mm bores.

cc or displacement difference will depend on if you put stock replacement pistons in or bore it and put dished pistons in.

No issues with 75mm pistons here.
Running for over 25,000 miles.

stock is 1331cc so it is to 1.3
witha 75mm pistons you get 1367cc, you could techincally call it a 1.4 but its really 1.37 lol

has anyone on here had their block tested to see how thick the stock bores actually are before? would be interested to know. i have never had a 4e/5e bored more than 20thou oversize.
