Dunno bro that was what was putting me off converting my N/A! I think it is quite a fiddly job tbh, try PMing Jay, he converted both Phil's & Joz's cars. Also I think Aze & Gaz@ Pukka offer a 4efte conversion service, you could ask them? They do Starlets, but I'm sure it wouldn't be too hard/different with a Corolla that shares the same engine?
