Same drivetrain as yours.

No, it'* not. The 94 has a Gen3 supercharger and a larger throttle body. The Gen 2 was used in 92 and 93 with a smaller throttle body. There'* a significant difference.

I thought the 92/93 only had 205 for the L67. 94/95 has 225, right?

My bad. That just answered a big problem i'm having with a freinds car that i'm working on. Parts store told me they were the same.

Yes and no. All of them were overrated.

92 was listed at 205. But there were some interesting changes in 93, and our experiences dictate the 93'* are quicker. But the rating didn't change.

Then the 94/95 were rated at 225.

Don't forget that power comes on ALOT quicker (lower rpm) than the S2. Our boost comes on quite a bit quicker too.

Hmm... cool. Our boost comes quicker than the S2. Awesome! I like the whine of the M62 better than the M90.

back on topic....

is the supercharger attached?

CORRECTION:

UNDERrated. Not OVERrated. My bad.

You may like the whine better, but it'* only because the S1 has to spin faster to produce the same boost that the M90 gets at a lower RPM. Heat and wear are worse for us. Our boost responds quicker, but at a cost.

Which is why our torque peaks at a lower rpm (desirable) and our cars fall flat on their faces while the S2 keeps pulling.

Yep, you should check the vacuum hoses, send out the injectors to get cleaned, and a few other fuel related items. There may be a problem there.
