Do U really need a muffler with a turbo? I am going to have my Supra's exhaust Ceramic Thermal Barrier coated. It reduces heat loss from the exhaust by 40%. I'm relying on that to keep the heat away from the transmission, the Diff and the Carbon fiber hood. It should work for U on the heat...

What form of heat insulator are U planning to use for the side exit exhaust?

... I'm the one driving up the costs! I was just reflecting on the total cost of this build; added to the base price of the Turbo Supra, the new Supra will cost ~$47,000, roughly what the MkIV cost new.

As can be seen from these pictures, a little rust. That will be dealt with before Wryann fabricates and welds on a mounting plate. Onto that will be bolted the rear wing brackets. They will look similar to these when it's done: New cost estimate for the project construction is now just north of...

I was there setting up just after 11 a.m. last year and by 11:30 folks started arriving. Most folks were gone by 3 p.m.

How long is the meet (11-3)? Any folks coming down from Canada, Idaho?

What are your specific goals and what size budget are you planning? It is helpful to understand where exactly U want to end up at; a time trial, a club SCCA/NASA class racing, or a high performance driving experience HPDE set up. Then build your car accordingly.

Eric, Your right... They will be fabbing up brackets to hang the bumper cover, under cover, splitter, plus stock grill parts this week. I hope to have more pics of the finished product. The bumper will be removable within a few minutes with the final design implemented. Two chasse bolts, five...

More bumper fabrication results: We decided that as the Supra is to become a Track Supra, we'd drop the bumper foam. The bottom bumper bar supports the splitter and the undercover. Both the front & rear bumper bars are TIG welded. Weight for front bumper bar is 19 lbs. vs 33 lbs for stock. New...

This new bumper weighs 12 lbs vs 33 lbs for the stock bumper. The new bar is made from 1.5 inch chrome molly.

That's a little more that I was expecting too. Before U spend that much on a design that may prove less than optimal on our cars, is there a way to experiment with the design using alternative materials like aluminum?

Here's an updated price list for the winter project: 2013 expenses new wheels and tires $1,300.00 new front brakes $1,130.00 new exhaust $440.00 fabricate bumpers $1,000.00 carbon fiber hood $587.00 carbon fiber hatch $616.00 install carbon hatch & hood...

I bought a pair of these, and I plan to have glass work done by a known body shop in Portland, to cover the top vent hole. Aesthetically, it just doesn't appeal to me to have a vent too close to the top fender line.

Josbeat, I would be safe in saying that U are on the right side of the argument for or against a diffuser, as I notice U are following a proven design from many race teams that have similar GT production cars using down force created by flat bottom floor tray and rear diffuser. I have seen a...

As far as a rear diffuser goes I may design and build one myself using a procedure I think looks promising...http://forums.nasioc.com/forums/showthread.php?t=2048621&highlight=rear+diffuser

http://forums.nasioc.com/forums/showthread.php?t=2048621&highlight=rear+diffuser Hi Josbeat, I found this interesting enough to send it your way... A DIY rear diffuser procedure.

From what I've been reading, you are very correct the effect of a diffuser creating more down force. It is an integeral part of any Ground Effects project for our heavy cars. I have included a web site for you: http://www.rapid-racer.com/aerodynamic-upgrades.php#Rear Diffuser

http://imageshack.us/a/img812/4124/1zsk.jpg Jos, I'm looking at this as my diffuser:

At this time, we're just doing the engine under cover in polycarbonate. I hadn't considered a full body under tray. With all the mods planned in the budget, I can't afford more aero, at this time. I'm on the look out for a used rear diffuser though... With a planned install after the first of...

Here are a few pictures: The first set is of the bumper spindle that the bumper will get welded to. Those spindles fit inside the former place occupied by the stock bumper mounts. This system will allow a mechanic to remove the entire bumper, after the engine under cover quarter turn buttons are...
