Recommened performance upgrades for '89 SPG? Posted by Wil W [Email] ![]() ![]() |
Its been a while since I investigated upgrading my SPG. I've been in grad school and conserving cash but have been itching to do so for a few years.
My SPG is currently stock at 165hp and is running well. I've been looking at SD and SPG9 for upgrades. Here is what I am thinking but wanted some advice. Goal is smooth running but with 200-230hp, it'll be my daily driver so I still want it drivable and not extreme. I don't want to spend a ton either, 500-1K would be my budget. Your suggestions and comments will are appreciated. I think 1-3 are necessary, do I need to do 4,5,6, and more?
1 - APC Upgrade (Red or Stage1/2?)
2 - Fuel Injectors (Red/Blue or 24#/30#?)
3 - FPR (3.0/RRFPR?, is 3.0 bar enough and does RRFPR cause rough idling?)
4 - New exhaust (Cat Back or 3" Downpipe all the way back?)
5 - HP Bypass or BOV valve.
6 - Air intake (Convert existing K&N drop in to high flow version)
