Oh ok and dont both of those modles have the single over drive gear set like the turbo modle in the tranmissions and i would think the 3.9:1 finnal drive gears to keep the motor spinning faster to make up for having less torque
Per 1988 FSM
EA82 SPFI = 90 horsepower at 5200 rpms........ and 101 ft/lbs torque at 2800 rpms
XT MPFI non-turbo 97 horsepower at 5200 rpms......and 103 ft/lbs torque at 3200 rpms
and all XT 4 cyl got 3.7 gears.....taller, not shorter than the standard EA82.
worth noting that those factory MPFI have 9.5:1 compression, not 7.7 like the turbos or a neutered turbo with dished pistons....as could be Jonos case?

well, you are only talking a 400 RPM difference. and I would bet that the MPFI still makes the same 101 Ft/lbs at 2800rpm as the SPFI......just keeps making a bit more up to 103 at 3200rpm
It get's a bit wonky with trans....4cyl, MPFI non-turbo XT got 3.7 final and just one OD gear (.871) in fifth. Same as the 3.9 SPFI trans
Only turbos and XT6 got the double OD gears.....(.972 in 4th, .780 in 5th)
Turbos in 3.7 final (some Single range, some Fulltime w/ difflock, and R/X with fulltime w/ difflock) and XT6 in 3.9 (fulltime 4wd w/difflock)

Story to this post is I discovered an error of mine.
I made a bracket for my LHD acc cable in my rhd ute. When I had to alter it I still forgot to check it did not interfere with throttle opening
I discovered it did, massively!
I could get a six mm drill bit between throttle body inside and the brass butterfly at max throttle. Six point five was too big.
A quick fix with hacksaw and caliper paint gave full throttle. Now this how I recall my mongrel
In aus we got lots of multi point injected ea82 in XT, in royals ea82 sedans and touring wagons all non turbo
My short is from an 87 touring wagon that I parted up with pristine 188,000 km. The heads are twin port turbo heads with longer stem exhaust valves. The inlet is from turbo coz needed to block off turbo coolant line below thermostat. It now runs impco 200 mixer and L converter and 22* btdc @800 rpm
My new saas tacho says idling at 1400 rpm.
It has this on cam like burst of energy at 6000 rpm. Heard from a guru ( Hi Greg) that hydraulics won't operate well above 6500 rpm, so starting to doubt new tacho when it tells me I hit 8000 rpm in second of five of my 87 touring wagon manual part time 4wd box whatever ratio it is on 175.70.13 tyres. Saw 80 kph at 8000 in second. I have an air filter box from aGM 3800cc v6 car and 2.75" induction tract
I dunno why ferp thinks it is an engine to suit industrial stationary purposes!!

Intake is mpfi twin port. Exhaust is ea82 efi y pipe then factory ea81 tiny stuff so is quiet. All the noise is from induction via Impco 200 mixer and box air box and panel filter. Impco throat is 2.75". Run 22 degrees timing @800 rpm. My fuel is about 109 RON. Highest pump fuel here is mostly 98. Some places have 100 and ethanol 85 is 107 RON
No flow work done to heads. Cams could be anything ...early turbo grind comes to mind.
Running 175.70.13 on H mags from RX. Tailshaft is out.

Which distributor are you running? How much mechanical and vacuum advance?
Does the EFI Y-pipe have the catalytic converter in it?
How about fuel mileage, and cost per mile in your part of the world?
