The dry sump pans that are used on the Daytona Prototype (Grand Am) cars here in the US dont have much more than 1 inch of draft below the bottom edge of the block due to the crank sitting up so high in the block. I think I have a similar dry sump on the shelf. I f I can find it i will shoot...

The temperatures you need to be careful of is not the temp of the oil, but of the heat from the turbo housing itself. Since the exhaust can get to the point of glowing, the most extreme temperature will come to the oil return line as radiant heat...

Check the "coil on plug" thread. There is a lengthy discussion of options and models that use this system.

My current combination of parts is as follows: 1UZ engine, Richmond Gear 6 speed, Castelmaine Rod Shop bellhousing, stock 1UZ flexplate with custom flywheel for Tilton multiplate 7.25" clutch. My project car is most definitely not a production Lexus/Toyota body shell, so I can make all of my...

Typically a copper gasket is only faced with copper. The material inside is soft enough to be crushed to shape and is heat tolerant. Something like fiberglass matt used for motorcycle exhaust could be cut to shape and sandwiched between the sheets of copper. Make sure that the outer sheets of...

Methaonol, as stated already, is corrosive to "bare" aluminum. Stainless components are the standard when using methanol, as it mixes readily with water and can allow corrosion on mild steel parts as well (doesnt burn to well either). It may even require changing the ignition curve as it...

Has any one checked the injection timing (phasing) of the stock ECU to use in an aftermarket ECU? I have worked up a generic surface of injection timing versus rpm vs manifold pressure, but was wondering if anyone had actually set up a scope on an injector and crank trigger to determine the...

the pics from SEMA are cool, especially the early 60's caddy (thats low) Surfer's is cool too. Never a bad place to be even if you have to work the week of the Indy.

Chuff, There is no means of adjusting the timing with the existing distributors. The spark timing is controlled by the ECU. Also, there is no mechanical or vacuum adjust on the distributors fro the same reason. If your final goal is a simple distributor system, then I'm sure you could rig...

LandCruiser coils Autronic, attached are some pics of the coils and the installation... the last pics is of the part number on the back of the coil. These coils, when seated to the oil seal in the cam cover, engage the spark plugs perfectly. The existing tapped holes are not the right...

autronic: I got a set of LandCruiser coils for $100US from a Toyota salvage yard in N. California. Good luck with the conversion. It made sense to me since I was going to use an aftermarket ECU anyway. Don't forget to get the harness side connectors... SteveO

The coils from the 98-2002? Toyota LandCruiser fit, if you want to do some rather involved modifications to the cam covers. It requires that you machine the cam covers and then weld in bosses to bolt the coils down. The coil covers (spark plug covers on yours) will not fit, but can be replaced...

The inlet and trhottle body are part of the way the sanctioning body evens the playing field when you have six different engine manufacturers with different displacements, redlines and torque curves. For what its worth the Lexus powered cars all finished the 24 hour race at Daytona this past...

Zuffen, The car "WAS" a Spitfire. There is not much of the original bodywork left though. Had to widen it 14 inches to get the SC300 rear axle assembly under the body, and added 10 inches of length because the car was starting to look a little too square. The engine will be run by an EFI...

Lambo, Your steering effort will be huge if you use the zero offset wheels. The bumpsteer, camber and castor will be the same if you are using the original subframe (or same suspension layout). This is refered to as the scrub radius, and has a major effect on steering feel/effort. If you use...

The series is: Grand American Sports Car series The class is: Daytona Prototype The cars are mostly tube frame (with some carbon structure), with carbon fiber boywork. The engines are based on production engines, but worked somewhat for race use. There are several cars entered with the...

1uz injector impedence 12.8 ohms. I had to check them for my ECU to be set up.

Coil on plug setup for 1UZ As mentioned earlier in this post it is possible to set up a coil on plug for a 1UZ, however it is a lot of work. I am in the middle of doing this conversion. The 1UZ cam covers have to be modified to accept the coils (not enough room). I am using a set of coils...
