Got the engine completely disassembled and ready to take to the machine shop today. These pics are for my reference when I go to put all the bolts back later

And here is everything wrapped/bagged ready to go to the shop Each piston/rod assembly is in a freezer bag labeled 1 thru 4.

While everything is out of the car I decided to rotate my square bushing. For those of you that don't know, on E-series transmissions (MR2 SC and MR2 Turbo) there is a little square metal bushing in the shift lever assembly that wears out and causes play. Here's the shift lever assembly

In this pic you can see the bushing in the middle. It's where the top arm articulates the bottom arm to move it in/out of the transmission.

Here you can see the amount of wear

All you have to do is take it out, turn it 90*, and put it back. Then all your play is gone! Hooray for free mods!

So while everything else is away, I'm taking all my cast intake components and starting to clean up the innards where there are casting imperfections. Nothing crazy, I'm not removing much material or reshaping anything. I'm using pretty much the technique used in this video, though I'm using a flex extender thingy for the dremel so I don't risk gumming it up with shavings.


Here's how my intake manifold came out. I'm pretty pleased with it.

I'm also porting everything to match the gaskets. Oddly, the cylinder head intake and intake manifold are already gasket-matched so I don't have to do that, though I will probably smooth out the casting in the ports in the head with very light duty abrasive fuzz attachments. Again, nothing crazy, no mirror shine (ain't nobody got time for that) just a little smoother. I wonder if there will be any measurable power gains once it's all back together with the higher compression and this intake work. If I could gain 10whp from all this that would be sick nasty.
