[Supras] New Built Engine, Gas Mileage Q's.

[James W.]

Alrighty, So, after having been into Mk3's since 2001 (Yeah, yeah, I wasn't exactly the oldest member in the SOGI Rosters :)) I've finally gone and gotten my engine built like I'd wanted it done in the first place:

- ARP Hardware (Rod bolts, Head studs, etc.) 
- Clevite 77 Bearings
- JE 0.020" Over, forged pistons
- HKS Metal Headgasket
- Machined and balanced crank/bottom end. 
- Generic head work, 3 Angle Valve job, re-shim'd buckets to spec, etc.
- Block/Head Milled to 30 RA smoothness. 

In hindsight, I'd of looked into shotpeening my rods, but that's another story.
Then I had some extra mods to install while I was at it:

- HKS long runner cast exhaust manifold
- HKS external wastegate
- Garrett 57 trim twin-scroll turbo
- Greddy FMIC w/hardpipes
- Oil Filter Relocation
- Seriously upgraded Oil Cooler w/thermostat
- Ford Contour fans (Sweet jesus these things flow some air)
- Zeitronix ZT2 Wideband O2 (To go with my VPC/S-AFC II/AVC-R Setup)
- Walbro 255 Fuel pump
- DXD Southbend Ferramic 6 Puck, sprung hub clutch (should be good for 550ft-lbs) 
- 3" VBand exhaust from turbo on.

Yup. I've got 550cc's + VPC ROM to go in, but I haven't pulled it apart to do that yet. Either way, back to my question. While I don't mind paying for the premium for this guzzler, what kind of mpg are usually seen for a setup similar to mine? At this point I'm breaking everything in and I'm just curious what I'm likely to see in the future. It sure as hell seemed to love it's first tank of new Chevron 91 octane.

Thanks,
James W

P.S. A Hearty hello to Tony and Ryan (Local NM guys) if they're still in the SOGI List.
