I don't think it'll work. The lift and duration on the 5E is likely to be different (Probably less) than that of the 4E (Turbo = shifting more air), so you wouldn't get any gains at all and might even lose power. I could be wrong on that though, I don't know the exact tech specs of the two cams, assuming they're different.

I know alot of the Lancia/Fiat boys use n/a cams in the 8/16v turbo engines for more torque. Im sure someone can tell you alot more than me though.

I read on here that an old member called "Tom Smith" who had the silver Glanza with Varis Carbon bonnet on, that had 5e cams in it.

Im sure a hand full of people have done it to be honest.

quite the opposite, 5efhe cams have more lift and duration than 4efte cams and are a straight fit back once properly shimmed
there are gains to be had by putting in the fhe cams.

Yes the 5efhe cams fit bolt on on all 4e... engines i know pwople who run the on n/a 4efe and also 4efte!


But only the 5efhe cams have mor lift and give you some power!

I had 5efhe cams in my old car... it made 238bph at 1.1 bar on a small td04

It felt like it had a little more pull off boost for sure - hard to tell on boost as i swapped to td04 at the same time.

Worth doing if you can get a set.. i didnt pay much for mine

going slightly of topic here, lol. is the 4efe head exactly the same as the 4efte head? could the 4efe head be used instead of the 4efte? thanks.

yes

but i think the valves and valve springs may need changing, i am currently in the process of finding this out.

i just checked the toyota epc and they (4efe+4efte) use the same head, valves, springs, cams etc etc etc :)
