Sierra mk1 coupe OHC to V6

Hi

My Sierra awaits till i get my garage cleaned up so i can start floorpan repairs.

Meanwhile im looking for all the info i can get.

My question is if engine mounts will need a rework? Will i need a new mounts, rubber pads only or will the engine fit the current mounts and rubbers?

Currently theres a 1.6 OHC and id like a 2.9 mk1 Scorpio engine in there.

You need the engine mounts from a V6 sierra, the scorpiomounts may fit but i don´t know.

You also need a V6 gearbox and starter.

Hey...

Ive got my hands on a 2.4 V6 ARC with a tranny for really cheap.

One thing that troubles me is the VAF (Volume Air Flow sensor).

I cant see one on my engine and the question is why. Were all the V6 fitted with a flow meter, or maybe FM were fitted only to newer models?

Ive seen videos of ppl running V6 (2.4 or 2.9, these are pretty much the same) without these sensors.

Should i need this sensor? Or would the motor run without it?

From what i see the readings on the sensor are:
flap closed: 0,25-0,6V
flap opened: 4,6-5V

From what i have found the TP (Throttle Position sensor) reads:
flap closed: 0,5-0,7V
flap opened: 4,3-5V

These are very close readings, would it be possible to wire the ECU to the TP sensor instead of VAF (which are missing?)

This is clearly a theoretical approach as i wont be fitting this engine anytime soon(bodywork).

You probably have an MAP sensor instead ?

Might be... i havnt had time to look closely enough on the engine as i just got it.

Could someone mark me a place in the picture (some engine compartment pic?) where should i be looking for MAP?

Okay... its the later model with MAP and 2 lambda probes. TY
