2.7 ETA Performance; Chips vs. Motronic upgrade vs. ?

[jmc1590]

Can anyone comment on the gains and power band I would get from the following:
5) Motronic 1.1/1.3 upgrade with all the above + i cam and i valve springs.

Using an '86 eta, Motronic 1.3, i cam & valve springs, I got 130HP/150 torque on a dyno. Not a huge gain, but well worth it in my opinion. I have since changed to a Seta lower end, and a reground cam (274, I think.) I've yet to find a dyno near by, but after 3K the motor really wakes up.

I can only imagine what a good tune would add!

Absolutely worth it (5 specifically), but you'd still need a chip to be running right.

Thanks for the reply. I haven't read through the entire Motronic upgrade thread. I was under the impression that it ran off the stock software. But I suppose a chip isn't a big deal after swapping all the other stuff over. I just can't seem to find any info on how much of an upgrade this actually is, and how it compares to just a chip, or how it compares to a 24V swap (M50 or M52).

My biggest curiosities are:
1) What kind of power comes out of 4 and 5.

2) Where these different options sit in with one another, and if there are big gaps between any of them. For example. Is this pretty accurate?:

Stock ETA < Chipped ETA < #4 < Stock 2.5i < #5 < 24V swaps

4) Motronic 1.1/1.3 upgrade with completely stock 2.7ETA, i intake manifold, i throttle body, i injectors, i AFM(air fuel module), i FPR(fuel pressure regulator 3.0bar), all i pulleys(fan, water pump, crankshaft), i belts, i thermostat housing, i 173ecu(computer in glove box), all 1.1/1.3 Motronic harness and sensors, spark plug wires.
5) Motronic 1.1/1.3 upgrade with all the above + i cam and i valve springs.


Are 4 and 5 worth all the effort and extra cost over a chip? Is there a significant difference between 4 and 5 (i'm aware with 4, i'd have to physically limit myself to revving past 5K. I'm fine with that). What are people spending on 4 and 5 these days? Any other options that i'm missing?

I have an '86 bone stock ETA. I'd like to get some insight on my options for performance upgrades. The car is a 3rd car for me, and a weekend/fun car.

I would strongly prefer to:
-Not remove my head
-Not need to rev super high for power
-Not spend too much money, as the cost of an M50/M52 swap (though more work) isn't that high these days.


Can anyone comment on the gains and power band I would get from the following:
1) Turner/Conforti chip $199: 24HP/28TQ
2) SSSquid chip $140: No published gains
3) Mark D chip $209: No published gains
4) Motronic 1.1/1.3 upgrade with completely stock 2.7ETA, i intake manifold, i throttle body, i injectors, i AFM(air fuel module), i FPR(fuel pressure regulator 3.0bar), all i pulleys(fan, water pump, crankshaft), i belts, i thermostat housing, i 173ecu(computer in glove box), all 1.1/1.3 Motronic harness and sensors, spark plug wires.
