Maz-yota -or- Toy-zad

"Ok"....I can't find it! But, I know that some one in here will know!

What class would a 1980 Toyota 2-wheel drive short bed pickup truck with a late model Mazda 13-B 6-port rotary engine, Mazda 5-speed and Mazda 4:11 pos-a-trac rear end fall into.


Thanks!

[Crazy_Dog]

it would fall into wtf class.....


I'm loads of help this morning, next question!

[Unstable]

The Pickup would be in HS or FSP.
With the engine swap it would go to SM2.
If it had been a Mazda PU AND the engine came out of a car that runs in FSP then the truck could stay in FSP.

I would shoot for SM2 or a mod class.

"Ok" thanks and now if I can get it done before the race'n begins!

That begs two questions.

Why would someone destroy a perfectly good toyota pickup by installing an engine from another manufacturer in it. LOL!!

Why HASNT anyone done this to a B2000 pickup? That would ROCK!

I destroyed one by slamming a Buick V6 in it.
Very good driving truck, I miss her.

Actually I think someone has, just not autox'd it .

SM2 requires an engine from the same manufacturer as the chassis.

It's going to be one of the mod classes, likely DM or EM. Page 152 of this PDF file should tell you which:

so if I put a 2.5l 5cy out of a 2007 VW rabbit in a 1982 VW rabbit truck, I can stay in FSP???????

that cant be right...

Yes Master Jim you are correct, I forgot the rule of make and engine.

All 4-cyl and rotary RWD
mini-pickups. (See Section 15.1.C for
update/backdate limitations.)

Section 15.1.C. Equipment and/or specifications may be exchanged between different years and models of a vehicle if (a) the item is standard on the year/model from which it was taken, and (b) the years/models are listed on the same line of Appendix A (Street Prepared Classes). The updated/backdated part or the part to which it is to be attached may not be altered, modified, machined or otherwise changed to facilitate the updating/backdating allowance. Standard factory installation methods, locations, and configurations are allowed. The updating and/or backdating of engines, transmissions or transaxles must be done as a unit; component parts of these units may not be interchanged. Cars
not listed in the Street Prepared sections of Appendix A may not be updated/backdated until approved by the SEB and published in the official SCCA publication.

When referring to his running teh rotary in the Mazda pickup, it was because Mazda actually built rotary powered PUs thus the updating could be done. I doubt the 5 cyl. & trans could bolt in a Rabbit PU but if it could the rules support the updating as far as I understand them.

J. Engine mounts may be replaced, but must attach in the factory
location(s) without additional modification or changes. Engine
position may not be changed. The amount of metal in a replacement
mount may not be increased relative to the amount of metal
found in a standard mount for the particular application. Solid
metal mounts are specifically prohibited. Any non-metallic inserts
may be used.

Best bet is to get confirmation from the SCCA itself before proceeding with such a venture if you plan to race anywhere outside of OMR.

The SCCA rules are not always cut and dry and are left open to interpretation. Like these -

S. Rotating and reciprocating parts may be balanced but not lightened.

O. Any metal clutch assembly, metal flywheel or metal torque
converter that uses the standard attachment to the crankshaft
may be used. Non-metallic friction surfaces (e.g. clutch disks)
are permitted. Dowel pins may be added. Any hydraulic clutch
line may be used. Minor repositioning of the clutch slave cylinder
is allowed to accommodate the alternate clutch, but the unit
may not be relocated and the repositioning may serve no other
purpose. This allowance does not permit the substitution of
slave cylinders or the use of non-original methods of clutch
actuation (e.g. pull type versus push type).

X. Any crankshaft damper or pulley may be used. SFI-rated dampers are recommended. Supercharged cars may not change the
effective diameter of any pulley which drives the supercharger.

Y. Any accessory pulleys and belts of the same type (e.g. V-belt,
serpentine) as standard may be used. This allowance applies to
accessory pulleys only (e.g., alternator, water pump, power
steering pump, and crankshaft drive pulleys). Supercharged
cars are excluded from this allowance. Alternate pulley materials
may be used. Idler pulleys may be used for belt routing in place
of items which the rules specifically allow to be removed, such
as smog pumps and air conditioning

I guess an official definition of "rotating mass" is necessary to understand these rules. Best of my recollection, when balancing a set of rods and/or pistons you take the lightest one and remove material to get all the rods to the same weight. But that is lightening. Replacing a cast flywheel weighing 20 lbs with an aluminum one that weighs 7 lbs. is lightening the rotating mass just like replacing the heavy factory pulleys with lighter weight aluminum ones.

Confusing but unless you are going on the NT or to the Championships it is not that big a deal when there is no contigency moneys on the line.

Oh yeah, WTF!!!!

[RacinAlt]

Probably DM.

I thought all wankles went to EM...
