3sge 3. gen. tuning Options

[TARManiAC]

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

The add list I´m aware of, but thanks for the reminder.

Theres no damage to my engine. No strange noises and oil is almost clear when it´s changed every 10K km´s. Also NO metallic flakes sticking to the sumpplug.

Unless you are familiar with racing Companies in denmark you wouldn´t know them. It´s 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 I´ve learned that mild cams at circa 264* are just that, that´s what I told them to make.

Yes I´m aware what ecu I´m 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 ecu´s :-)

I know what a Knock-Link is, used it in my WRX some years ago. Same with wideband. Those are for monitoring, just as I´ve 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 haven´t 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?
