I have an update for Street Mod.

You can no longer just use "any nissan engine" Since the update/backdate revision, the only two engines you could use in the case of our cars would be the KA24DE and the KA24E. You could only upgrade from the E to the DE (Or even downgrade for whatever the reason) But no SR20 because it was not offered stateside in the S chassis and definitely no RB/VQ etc.

An example local to me is a 1986 Prelude running a b16a2 from a 99-00 Civic Si. It was legal until update/backdate because it was a Honda engine. After update/backdate the car became an XP car and was basically useless for anything other than a bunch of fun.

Likewise, putting that same b16a2 into a 96-00 civic ex/dl/lx would be completely legal for SM.

RB/VQ yes, but are you sure about the SR?

From pg 117 of Solo Rules book:

Engine block must be a production unit manufactured and badged the same as the original standard or optional engine for that model. Badges that exist as marketing aliases for the manufacturer will be recognized as equivalents... This allows engine blocks manufactured as production units for sale in other countries such as Japan or Germany.

From that, essentially, I interpret that as the following: as long as the engine was in the chassis somewhere in the world as a production model (i.e. sr's & ca's), then it is legal for SM.

Hey QV! Good to see you here on Zilvia!

But anyways, I have seen many 240s that have participated in solo2 events with SR engines that have been classed as SM or SM2 basically.

It would kinda suck if SCCA banned 240s with SR engines from competition.

If that happened, I figure there'd be a riot, haha.

Update on STX:

You can run up to a 9" wheel with a 265 tire on a 2WD car

Still 245 for an AWD car.
