Hey, guys I'm a first time supra owner and have had my car for about 5months (bought old skool's 91T). I'm slowly acquiring parts and hoping to get all the parts I need by April and get this going asap. My idea is to try to find quality parts for reasonable prices. Looking to hit high 400s or maybe even break into the 500s on the stock block and a good tune, but I'm not sure if the 550s and walbro 255 is gonna hold up but we'll see.

What's in the mail or waiting to be shipped is

-MAP ECU 2 ($432.60)

What I still need is
-Reservoir for meth inj
-T25 to T3 adapter
-Intercooler (actually found a treadstone TR10, just waiting for the seller to get me more info)
-IC piping, not sure if I want to go with Al because I can't weld Al, so I might have to go with mild steel
-Misc oil lines, mandrel bends, etc.

Sorry for the late update, just uploaded the pics of what I did a few weeks ago. Intercooler, manifold, and turbo are on. Colder plugs are in, changed the valve cover gaskets, and mapecu2 is all wired up.

Things still to do are:
-Aluminum braze my blitz bov flange on to charge pipe
-Fab a DP with toyota O2 and wide band O2 bung
-wire up the LC-1 to mapecu2
-put the bumper back together, it turned out I didn't even need to remove a single bolt from the bumper to put on the IC. Its kinda ridicules how many nuts and bolts are needed to remove this thing...
-hook up all necessary vac lines
-finish up the charge piping from turbo to ic
-maybe fab a wastegate dump tube...
-tap charge pipe for methanol injector
-mount meth pump and reservoir
-relocate PS reservoir
-drop the tank and install walbro 255
-hook up turbo coolant lines to the hx40
-relocate oil cooler
-2step switch
-and a good street tune!

Won't be able to work on this till next week but hopefully by then this thing will be up and running

Looks awesome! I'm sure you know, but in case you don't, you will have to run a restrictor in the oil feed line to the turbo.
