why would you swap out your 3.4 DOHC? i mean the n/a 3800's are nice but not to the power of the 3.4 DOHC man!

if its knocking then i guess if thats what you have, work with it.

I think he is talking about the supercharged motor

 

there are a few options. you can drop that motor in using buick regal parts and engine harness and getting a chip burned

 

you can use the L67 which is the series 2 and do the same thing with the regal harness and use your stock trans.

 

next option is L67 motor and trans and add the wiring to the data port inside your car for the OBD 2 stuff.

 

any one will work it just depends on power and reliablity

you can use the L67 which is the series 2 and do the same thing with the regal harness and use your stock trans.

Actually the RPO code for the Series I and the series II S/C 3800's are the same.

s/c your 3.4

[brianteel]

i know they use the same code....i dont refer to them that way because it is to confusing for some people

what kind of HP does a stock series 1 SC 3800 put out?

[brianteel]

i think it is 220

[99RegalGS]

91-93 = 205hp and 260tq

 

94,95 = 225hp and 275tq

You can get more boost from the 94,95 just by putting on the 91-93 pulley.
