New Sleeves for the FA20 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Hey everyone LA Sleeves has come out with a NEW sleeve design for the FA20. LA Sleeve told me they would take 50 PSI of boost no problem. Now I just have to figure how to keep the heads on at 50PSI....I love a challenge... More pics on my build thread "FT86PROJECT9S"

Shouldnt be there NSFW warning?

Nice to see another company supporting the platform. Honestly the stock sleeves are good to 750 WHP though.
I went with Darton for more displacement and a closed deck.

I was told by LA Sleeves that it would be no problem to punch it out to a 2.2 liter I believe that's 89mm. Outfront Motorsports is looking into building a closed deck version FA20 but they are in the R&D Stages of that now.
This is one of there EJ closed deck.
Your Darton's do look sic tho

Closed deck + O-ring the block ?

I'm more concerned with lifting a head. I have not seen anyone push more than 30 psi. It's uncharted territory on if the head studs will pull out of the block or stretch or break. The Dyno Day will be very stressful

Forged Performance in Australia is waiting for some custom Head studs to stop lifting the head. I want to say like 13mm Diameter

While nice. Piston rings, rods, heads ... Etc. are the things that are going to go first.

think about oil pressure and wearied parts

On the street oil pressures are no problem' I only go a 1/4 mile at a time on the track so again oil pressure will be fine. I will leave it to Element Tuning to push the circuit track, they seam to have the oiling issues down to a science.
At first I thought about oiling issues but after calling in some of the pros we are confident it's not going to be a issue. We did do some clearance and oiling system mods, and I will report any issues thru my build page.
