Since my 4Banger is only on 31MTs (not 33/35MTs) I figured I wouldn't be throwing too much money away if I worked on the engine a little more so it could maybe turn the 31MTs on the highway a little bit more strongly on the stock 4:10 gearing. If I'd been on 33/35s for tires, I'd have just gone straight to 4:88s and not messed with the engine.
With the current setup, it is getting way old sometimes having to drop to frigging 3rd gear, doing 60mph at 4000+ RPM on some grades and falling behind all the grandmas/grandpas waving at me, cruising by me at a steady 65-70mph speed limit. Headers may not help a ton for this, but they probably won't hurt. Can live with dropping to 4th no problem, but not 3rd.
I ordered some Borla 4Banger headers Model # "17058" since I've had one of their cat-backs for going on 7 years. Liked the long-tube design on the PaceSetter Ceramic coated 4Banger headers, but figured I'd stick with the exhaust make that has worked ok for me thus far.
According to Borla, these "17058s" are apparently the ones that fit the 91-95 4Bangers. Thing is you search around for "17058"s and surprisingly few place sell them.
Anyway, once I get them in there I might throw a header-wrap on them also -- figure the stainless tubing won't care. And I've had good luck with header wrap on a different vehicle.
I could also mail them out to get Jet Hot coated before installing them
Will probably follow all this with an electric fan out of a junk yard. And try not to add any additional weight to the vehicle (yeah right
)
