95 SC 3800 mods??

'95 SC 3800...
What can I do?
( I have a mandrel bent free flow exhaust, and free flowing air filter.)

Do you have the Series 1 or 2 3800?

 

[95scpa]

Series 1 with the M62, from what I've read, and pictures I've viewed so far...
I measured the pulley diameter at 3" already...
There's NO "U-Bend" like newer Regals etc..

Are these just forgotten performers?
Or is there an aftermarket for them, even a limited one?
Can I retrofit an M90 + intake onto the Series 1 long block?

I think it's really quick for a larger car...it pulls hard regardless of what road speed.
I'm picking up a BOOST Gage soon...is there a pillar mount that will fit decently, even modded?

Thanx for the reply..

Go to http://www.pulleyboys.com/ They have smaller pullerys for the SC.

Are these just forgotten performers?

Yes pretty much, aside from doin a custom intake and exhuast.

Not sure but I doubt it though. The Series ! & II are totally different.

I feel your pain. I was in the same boat when I had my 92 Park Ave and mine didnt have the SC so I couldnt even do that. I did do the exhuast and a FAST chip. As a matter of fast I still have the chip if your interested.

Thanks, I was afraid of that, it's a shame too, these cars are pretty quick for their size, great sleepers!.

My car is OBD II, so I think the PCM has to be reflashed and can't use a chip, is that correct?

 

[95scpa]

Ok, I went to Pulley Boys, and they have Series I pulleys in PLENTY of smaller sizes, all the way down to 2.0"...mine is currently @ 3.0" stock(series I)
I noticed you seem to drop the Series II pulley size by .4", from 3.8" down to 3.4"...Would it be safe to assume the same for a Series I motor???
Which one is recommended for: stock PCM and Injectors etc
Then: What would be a next step? PCM reflash + Injectors + even smaller pulley??
Thanks again bro!..

Yep. You may try Intense Racing or DHP and see if the can do a custom burn for you.

Not sure, but I do know the M62 blower has to work harder because its smaller than the M90. You may want to consult Bonnville Club for that. Theres a lot of guy on that forum that have done that.

If you do get a smaller SC pulley get a 180 thermostat, K&N filter,and possibly 1 heat range colder plugs.

pull that m62 and get it ported and polished

put a m62 pulley on an m90?

do any of you know if an m62 pulley would fit on the hub of an m90? I have a 95 riv sc with a seized engine and wrecked up body. If the pulleys would fit, it would be a cheap way to get a 3" pulley for my series 2. Thats about the smallest pulley you can run on an m90 w/o an intercooler -- perfect! I might just have to try that today!

No because the M62 pulleys are keyed were as the M90's are press ons.

Correct me if im wrong but my 95 Riv with the series 1 motor has an OBD I computer with the OBD II wiring. So wouldn't your 95 Park have the same exact wiring as my 95 Riv? But the regalgs (www.regalgs.org) board would be another place I would try and ask your question.

Pardon the shameless plug but I specialize in doing custom chips for the 94-95 3800 SC computers at a very attractive price. Let me know if you need any help.

Yes, you are correct, my 95 PA has OBDII wiring, but a different ECM or pin-out. I've tried several scanners, and all had to use a special cable for 94-95 models....I'm not sure why, I haven't looked to see if it has a removeable chip or not, but I will.

I'd love to get a chip, or reprogram, just want it for a Pulley Boys 2.5-2.6" pulley, and the correct injectors, but I'm not sure what size?#
If you know what size injectors I have and I need, I'll order the Pulley soon, then hit you for the reflash!

 

[Darth Fiero]

95scpa, the 94-95 computers have a removable mem-cal (which the chip is part of). As for stock injector size, I believe they are approx 28 lb injectors on the stock 92-95 3800 Series 1 SC engines. The series II 3800 SC engines come stock with 36 lb/hr units so you might want to think about upgrading as well.
