Pics Inside the 2017 Red Manifold? - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

Williampreza · 01-25-2018, 06:00 PM

Anybody have one of 2017 intake manifolds off the car, or have the throttle body off, that could post pics? Would like to get an idea of the finish looks like on the inside, e.g. casting marks, rough or smooth finish.

Thanks!

Sounds like it would be a good candidate for the polish part of the old "port & polish" routine.

I'm thinking an extrude hone might bring out a couple hp. It worked on the Honda B- engines. May be worth a shot...

I don't know how you would measure a couple of horsepower. Seems that these cars vary a couple of horsepower every dyno pull.

Welp, some folks go and put a "slicker" inlet tube on the car and thinks it makes a difference ........ so, a slicker intake manifold should add at least that much HP ...... but, since people cannot "see" it ....... it may not. Plus, it wouldn't have a "sticker", so, you may be right .......

Is it as rough as a badger's arse? Port & polish with a blueprint..

I doubt there's anything to gain on inlet side unless you go fi.

Thanks, but I'm working on something a bit different.

Okay, so on a related technical topic, I could remove the throttle body and check for myself, but I don't know how delicate the new paper gasket is. It's a fairly young car (8000 miles). Would I be wise to have a spare handy or skip it and crack her open?

He wants to know how is the INSIDE of the manifold. You're probably talking about the OUTSIDE.

If you would change the word "anything" with "much" ....... I would agree with you ...... don't forget about the stickers ......
