I should mention that this will be a track only car, I instruct for a number of clubs in my area, so there will be a lot of track time, and once the car is sorted, a cage will go in for W2W. My previous race car was an E30.
1. Since I have a 2020 MY, it seems that all I need is a longer sleeve to connect to the air box and possibly a new filter (Blitz seems to be the recommended brand)... can I stick with stock or is there just too much restriction?
Is there anything else that is required for 2017+?
No that should be it
2. I am leaning towards Jackson dual rad/oil cooler, some people in this thread mentioned that they are using it, just wondering if anyone with a SC is tracking with this set-up, and if there are any cons?... I will be venting the hood too, mostly for aero, but should help with keeping the temps down.
oil cooler with a thermostat is a good idea and the beatrush undertray also helps keeps temps down
3. I should have more than enough power for the class I am aiming for with this SC, all I care about is reliability, so with that in mind:
a) Can I keep the stock exhaust (don't care about sound)? - [I]yes you can[/I]
b) Not because of power, but just to avoid any knocking issues, which octane?
I have easy access to:
91 no ethanol,
93 and 94 with about 10% ethanol,
and almost any octane non-ethanol race fuel - 94, 98 and 100... it's just bloody $$$[I]
94 octane with 10% ethanol will work well - the tune comes with 91 and 93 octane maps as standard[/I]
4. Please see attached picture - is this normal or just loose? Couldn't really check it at the time, and now the box is buried behind a bunch of crap (just a little paranoid).
why do you think that end cap is loose? the cap may not be 100% lined up but if the button head screws are tight it'll be fine, the cores are sealed in with silastic too and you almost don't need the screws
5. Engine oil - leaning towards 5w30 to start, will monitor temps and pressure. - [I]definitely, the stock 0W20 is too thin, also if your tyres are better than stock I'd strongly recommend a sump baffle as the pickup gets uncovered in long corners[/I]
6. Got a catch can, just because it makes me feel better. if you like but I'v e not found any need for one
I am sure that I will have more questions, but that is it for now. Thank you all!
