Rallywagon Posted June 23, 2005 Share Posted June 23, 2005 What years used the throttle body injection and what used multipoint? Advantages, disadvantages, opinions? I need good gas mileage for commuting, but I also do some offroading. Thanks. Link to comment Share on other sites More sharing options...
ballitch Posted June 23, 2005 Share Posted June 23, 2005 well i think all legacy's have multipoint and all loyales from 87' ,or whenever they started, up thru like 91. but i think after about 92'-93' all SPFI were replaced with the MPFI, MPFI has better control over fuel dispersal per cylinder than SPFI, obviously, and gains you fuel mileage as well as a few ponies to boot. if you want fuel injection but dont want a ton of computer stuff to go along with it, use SPFI, vice versa apllies. but if you want more power and beeter gas mileage and a little more power go with MPFI. hope this helps. ~Josh~ Link to comment Share on other sites More sharing options...
Rallywagon Posted June 23, 2005 Author Share Posted June 23, 2005 Did any of the dual range wagons come with MPFI? Thanks. Link to comment Share on other sites More sharing options...
KStretch55 Posted June 23, 2005 Share Posted June 23, 2005 I've got a '91 Loyale MT and a '92 Loyale AT, both wagons and both SPFI. Link to comment Share on other sites More sharing options...
NoahDL88 Posted June 23, 2005 Share Posted June 23, 2005 MPFI only came on "premium" cars, all turbo, and some XT's all XT-6's I don't know about RX's but a good rule of thumb is that if its not carby, its probably a SPFI. Link to comment Share on other sites More sharing options...
calebz Posted June 23, 2005 Share Posted June 23, 2005 SPFI - 86-94 L-series. Not all, but most (except 86 and 87, which still had a number of carbed cars) MPFI 85 L-series wagon (rare) and some various years of XTs (N/A), all EA82 turbo cars. All legacy and newer subarus. Also, all of the turbo cars are MPFI. No dual range MPFI cars that I am aware of, except the RX, which has a little differend DR than the others and is turbo.

Any EASY way to put SPFI or MPFI on a older D/R vehicle. Is it worth it? Link to comment Share on other sites More sharing options...
subynut Posted June 23, 2005 Share Posted June 23, 2005 SPFI is easiest. The SPFI and hitachi 2brl carby intake manifolds user the same heads. MPFI would require swapping heads. SPFI uses less wiring too. Link to comment Share on other sites More sharing options...
WagonsOnly Posted June 23, 2005 Share Posted June 23, 2005 Why not just find an MPFI car and drop a d/r tranny in it like Dennis did with his XT? I don't know if I'd take a turbo offroad though. If you're interested I have an MPFI nonturbo RX 3-door with a d/r FT4WD tranny, locking diff, rear LSD Link to comment Share on other sites More sharing options...
