Hi. Iīm about to do a complete overhaul on my 3. gen 3sge. Bearings, toothbelt, seals, gaskets, and pistonrings. And while Iīm at it I thought, hey why not have
some fun at the same time. So now I got St205 brakes and a s54-06d gearbox waiting for installation too. Itīs making 188 hp on 95 octane (we have 98 in this country) with a decat and KN panel filter + an alu lightweight crankpulley. I īve done a lot of research on this engine and I think I have a pretty good Picture of what I want. Iīm going for re-shaped cams, a good maschinist shop will make them into 264*. Iīm going to up the compression by shaving off the head, install a Fidanza flywheel, make a cai into the oe box along with supporting mods like Magnecor leads a wideband lambda sensor and perhaps an adjustable fpr or high capacity fuelpump. No piggyback or standalone at the moment, but it is on the list for future mods. My thoughts are: 1. how much can I shave off the head? I once read somewhere (canīt find it anymore) that 1mm is ok. My concerns here are mainly detonation, but also piston/valve contact (but I donīt think so as this engine is a non interference engine), and cambelt slack. 2. will the oe green injectors be able to deliver enough fuel? I donīt know how much they are rated at. Thank you for reading ![]() |

The add list Iīm aware of, but thanks for the reminder.
Theres no damage to my engine. No strange noises and oil is almost clear when itīs changed every 10K kmīs. Also NO metallic flakes sticking to the sumpplug. Unless you are familiar with racing Companies in denmark you wouldnīt know them. Itīs a Company that I trust and I tell them what I want and they make it from the oe cams. I told them cams should still be streetable, and since Iīve learned that mild cams at circa 264* are just that, thatīs what I told them to make. Yes Iīm aware what ecu Iīm using, and I can still make adjustments. NO, not with the ecu. But there are other ways of adjusting. History of tuning engines started way before there was something called ecuīs :-) I know what a Knock-Link is, used it in my WRX some years ago. Same with wideband. Those are for monitoring, just as Iīve explained. What I asked was, if I could hook-up these with the existing oe sensors. mi645 I really think you need to start from the beginning. In my first post I specifically mention my reasons for asking how much can be taken of the head: cambelt tension and piston/valve contact. So read away LOL. BTW what do you mean by "he"?? BUT I still havenīt heard from the NA tuning gurus in here. How much material can safely be taken off the head of a 3. gen- 3sge?? Anyone knows where Pasqual went? |
