im looking to throw in a obx lsd on my h22a4. it has original tranny on it. ive read that a obx lsd doesnt fit on preludes type sh models. need to know if a h22a4 is the basic model or a sh model?

 

It's the engine code for both the base and sh models. And the LSD won't work with the SH model, because the SH comes with ATTS (Active Torque Transfer System) instead of an LSD.

Look for this big thing on the back of your engine, where it meets the transmission:


If you don't have that, and you just have the intermediate shaft bolted on, then you have the base engine.

 

i do not have the tranny apart is there anyway to know without taking apart?

 

is this thing sticking on the drivers side of your transmission underneath the intake manifold

 

yes my h22 does have that atts on the back. so i guess no lsd is there any disadvantage about this?

 

my buddy had a prelude SH and the only good thing about it really is theat it comes with painted side skirts lol, he jus got done takin the h22a4 out and puttin the h22a in....atts sucks man if your tire pressure is low it throws a code or if you have a spare tire on it throws a code me personally it sucks
