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 ![]() |

Yearh thanks for the good info on fprīs Rusty. Sorry but I donīt know why horsepower is published the way it is here in europe. Those were the numbers I got from a free rolling-road day a couple of years ago. So why bother fixing a good strong engine you ask. Well, because itīs old, has nearly 280.000 kmīs under the belt, I want to use it as a daily driver for many years to come, and the most important reason: I might just take up my racing career again. It needs at least new gaskets, seals and cambelt. Then I decided on a lightweight flywheel and I thought, heck why not take the engine out and get rid of all the rust and gunk and give it a paint job. Then I found out I might as well stick some new bearings and rings in there. Itīs evolving ;-)
The alu crank pulley has been there for more than 40.000 kmīs so itīs staying ![]() As for the camshafts, I just asked a renowned Company if they could grind them to 264* since Iīve heard these would still be ok for daily driving. No serious porting apart from the intake and exhaust ports. no valvejob apart from cleaning and adjusting. Oe exhaustmanifold. No crank balancing. I know somekind of uprated ecu gives so much more (had them in my former race-engines), but for the moment Iīm going with a wideband and a knock-link for safe tuning. Power? letīs see, but I wouldnīt be surprised to see 200+. Compression? you tell me:-) but I think something like 11,5:1 is ok. But still the big question is: How much to mill off? NO you can NOT just mill away, very bad advise there. btw, is it possiblel to hook up a wideband and a knock-link to the existing wiring loom, so I donīt need to install extra sensors?
