Hi. I´m about to do a complete overhaul on my 3. gen 3sge. Bearings, toothbelt, seals, gaskets, and pistonrings. And while I´m 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. It´s making 188 hp on 95 octane (we have 98 in this
country) with a decat and KN panel filter + an alu lightweight crankpulley.

I ´ve done a lot of research on this engine and I think I have a pretty good Picture of what I want. I´m going for re-shaped cams, a good maschinist shop will make
them into 264*. I´m 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 (can´t find it anymore) that 1mm is ok. My concerns here are mainly detonation,
but also piston/valve contact (but I don´t 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 don´t know how much they are rated at.

Thank you for reading wink.gif

To add to the list oil pump, water pump, tensioners, clutch, flywheel bolts...

With the alu crank pulley, the crank sees more unnecessary movement & vibration that it was designed for. The factory one is a balancer. Yes it may have lasted for +40,000km's, doesn't mean it hasn't done damage to the engine.


What "renowned Company" for the camshaft work? How much increase in cam lift? Be careful with 'advertised duration' specs too as cam company's take the measurements at different points to make their camshafts appear bigger.

Best to stick with @1mm or @0.050" valve lift specs, so you can compare.



Safe tuning? There is no uprated ecu or piggyback, you are still using the factory ecu, so you cannot make any changes.

The 'KnockLink sensor' is just that... a sensor to detect if there is knock, then flash a light if there is knock. Have you been to Link's website? It doesn't wire into the ECU.
A wideband sensor is sensor that allows the air/fuel ratio to be measured. Again not really useful since you have no tuning abilities.

But as you said you don't want extra sensors, so you don't need these anyway
