lemme know how this worked if you tried it, or if you think it might.... im gunna try it in the next couple days and see what happens...
Ford Escort 2nd gen intake upgrade
From Mechanical Database
Jump to: navigation, search
A way to increase airflow as long as the electronics work with everything is to upgrade parts of the intake to newer models. The 1991-1995 1.9L Escorts can gain some additional power just by bolting on a later throttle body and/or air flow meter. The early 90's Escort 1.9L's had a very restrictive air flow meter. It has a center port that measures only 1.500" diameter. Later models (1993-96) have a much larger air flow meter. The way to tell is look at it from the end. If it has a small round port in the center and a screen, it's the early model. The later model has a vertical divider in the center and has no screen.
You will also need to remove all the ductwork from underneath it the air filter box. This is a major restriction. Just unbolt everything under the air box and pull it out. Also use a high flow air filter like a K&N. Here is the combination that will fit:
The air flow sensor is much larger and will flow better even if it has the cross tube. You need the air tube because the air flow meter is larger on that end. You will also need the end of the wiring since it is slightly different. Then just cut & splice the wiring. It will bolt to your air box.
The throttle bodies from 1991-96 are all 40mm. The 1997-up are 44mm. This doesn't sound like much but is about a 24% increase in flow area. The throttle body is an easy bolt-on. If you have an automatic transmission use only the 1997 throttle body from an automatic. It's the only one that has the provisions for the transmission throttle linkage, the lower cable.
* Air tube from a 1994-96 1.9L Escort
* Air flow meter from a 1994-95 (OBDI) (1996 was OBDII compliant)
* Throttle body from a 1997-up (1997 only with auto trans)
If a 3rd gen throttle body is used the throttle position sensor will need to be rewired. If car is a 1996 2nd 1.9L however, then no electrical modifications have to be done.
The position of the tang that turns it is different on the later cars so use a 1996-up sensor and reconnect the wiring as shown here to the right. VREF stands for a 5 volt reference voltage. SIG/RET stands for the signal return which is a dedicated ground circut for the sensors. There are a couple of things that will need to be changed. The mounting holes in the throttle body will need to be redrilled to a slightly larger size. Also, you should reuse your original idle air control solenoid which is mounted on the top. Reinstall it on the new throttle body facing the same direction as it was on the old one.
