ok 93 bonni’s still have the series 1 3.8 with the M62. There are many options that you can do depending on your cash flow. I would get a used L67 (series II 3.8) or L32 (series III 3.8) motor. The L67 has a GEN III M90 and the L32 has the GEN V M90. Swap that in and have 240hp (L67) or 260hp (L32) right away. Now if you want to make some serious power get a L32 short block, heads, and do your own turbo kit. Then watch as you pwn you tranny while you make 500+ hp all day long. A stock L67 short block has ran in the 9’s@140+

for tons of info and help on this subject. Remeber though, once you start making good power your tranny will take a shit.

I went with a small cam, IC set up and kept my M90 and have put down 273whp.
