Hi folks

Just picked up my EJ20 twin turbo GT-B wagon (75K miles) and have a few Q's.

- Recommended oil type & grade? Semi-synth 10W-40?

- I have an HKS panel filter fitted, what else can I do to improve breathing? I've heard a lot of negatives on fitting a cone type filter

- Vent-to-atmosphere BOV, is this a good idea (purely for the sound). I have an awesome SSQV fitted on my MR2

thx, Mike

5w30, dino or synth is up to you really. You may develop some leaks by switching to synth depending on the condition of the engine

Im not familliar with the TT intake setup, but removing any resonators in the intake can help

No.
