The TDo4 has a different delivery for sure, although once again, they start to come alive at a bar.
The fact he's using a 4EFE with that coil setup is interesting. The only time I've seen it was when I built a GT for Rab on here. We took the 4EFE from his sister's 'bug-eye' Corolla (E11 I think). I binned the crank sensor, coils and wiring because we were using the 4EFTE loom that was already in the car. Always wondered what would happen if one was boosted with it all in place. Would imagine it would be an improvement on the usual setup.
After seeing one in person though I figured retro-fitting one to our starlet 4EFE would be a fair bit of work. The crank sensor wouldn't have a recess to sit in and the distributor hole would need plugged for starters. Even the lower timing belt cover is different. I did keep the bits but finding them here might be a mission.
Anyone know what a Cyprian EP91 4EFE engine has as standard? Can't help but think that engine is stock and he's just boosted it using bolt-ons and a piggyback. A chat with him should hopefully confirm matters Sam.
Also - are those plugleads bothering anyone else's OCD?
