"S5 Vert Automatic Performance????"
 

I have a 1990 NA 'vert auto and looking to do some upgrades!

I'm having the motor rebuild.
Thinking of street porting it, putting pineapple sleeves, RB cat-back, drop-in KN airfilter (maybe a cone), porting TB.
LSd 4:10(or maybe 4:30 it might help on the pick up since its a automatic), RB spring, RB sway bars, maybe KYB AGX, thinking 3 point front strut bar. A roll bar (its a vert why not). stainless steel brake lines, and considering keeping stock rims as i think the stock rims are very lite.
Also wondering if adding SAFC II, SAFC NEO, or any other things you can thing about would help this auto NA.
I know changing to 5spd would help, but want to keep this a auto and wondering if anyone build an automatic that decent and that has any ideas to add performance to this automatic convertible to help from street to mild performance and maybe a little wild.
I know a turbo swap would help, or adding supercharge, but looking to see what possibility i have with an NA as im rebuilding one.

thanks :nod::icon_tup:

Update:
So far on rebuilding the motor, it looks like I might not port it and leave that part stock.
looking like I’ll be putting RB spring with AGX, RB sway bars, RB downpipe/presilencer and RB cat back, a drop in K/N filter, porting TB.
So far looking into installing a "CAMP" and getting a double din head unit for display and I don’t know about the SAFC II or the NEO.
Was trying to get a nice roll bar in eBay, but still looking around. Also they had a nice splitter for it but out bided in eBay. Keeping stock BBS rims installing new brakes, SS brakes, maybe slotted rotors. I interior looks great shape beside the seat and going to have them re-down.
It has a stock diff and looking around for the nice 4:30's LSD out there.
And last but least yes still keep the Automatic(down the road i change to stick) but for now want the automatic and keeping the Vert Auto not like my coupe. Want try find out there anyone have any Automatic performance upgrade etc? Has anyone down or have automatic with paddle shifting or other type of automatic up/down shifting ideas?????

Thanks
