Which alternative do you suggest?
4EFE vs 4EFTE engine block differences for forged engine build.

I was happy with using the fe camshafts but as they are different I will need to source fte camshafts pr buy aftermarket. I emailed Nippon Auto spares again but they are not answering. I’ll have to call them. Any alternative find fte camshafts? Thank you for helping out.

Most people just run ARP main bolts and not studs. However it is personal preference.
As for the aftermarket camshafts, I only know of Ivan Tighe in Australia, as Speedvision in the USA seems to have closed down.
You will need to swap the cam gears onto any new aftermarket set you buy.
Standard FTE cams are ok if they are in good condition.

You are right. I checked as well after we spoke.
Can we make a list of the different parts between the engines. I need to know if I can ise the FE block to be forged as a FTE changing only the oil sump and oil filter relocation. If the engine head is the same besides the camshafts I will have to buy them. Also the engine head rocket is different as the FTE has the oil breather. What else?

I haven’t found any deal yet. I really don’t know who to ask.

I checked and valves are the same on both engines. So camshafts are the only Zoem Part I have to source together with the oil feed to adapt the fe oil sump. Do you have any link to find the feed metal kit with washer?
The head rocket has the oil breather on the top right on the fe. It will work.

Hi Frankie, haven't had a great deal of time spare recently but Daniel is steering you rightly, there's a lot to be said for firsthand experience!
I would be checking the spec of the engine you are basing the build on first. If it's the Corolla engine I don't think the camshafts are shared in the 4EFTE nor are the valve springs as already mentioned.
Can remember someone saying the 4EFE and 4EFTE have the same lift and duration as each other but that could be wrong, if I can find the info in the manuals here I'll post it. You could also be working against some random production differences too, the E11 4EFE I turbocharged only had one bolt hole for the distributor for example. A minor issue but still threw a curved ball into proceedings!
Do you have any tech info on your 4EFE?

Oh and the 4EFE rocker cover will fit but the breather port a bit more restricted than the 4EFTE version. In fact it actually made an odd whistling noise when left open to atmosphere which the turbo breather doesn't. Just a case of piping it to an oil catch can to eliminate that noise.
(Or yours may not even do it, depends on crankcase pressure)

I can't remember Frankie it's a while since I researched it but I remember looking at the one in this link and getting the info based on the an8 fittings. As mentioned here you could hook up the oil catch can

I probably opened the thread in the wrong section?
