    after seeing the same posts on stuff come and go by with the same answeres, ive decided to start compiling info on the basic mods for the 1.9/spi.
    ----------------------------------
    :arrow: CAI:

    custom or aftermarket (5$-100$)

    expected power gains:
    1-5hp

    3.8/1.9HO TB ($15 at a JY) + be sure to port match the manifold for it-
    maybe +1-2hp and a really cool sound


    93-96 MAF swap if you have a 91-92 with the small MAF. ($15 at the JY) small gains.some 93's still had small MAF's.

    ----------------------------------
    :arrow: Header and Exhaust:

    -first gen HO header (20$-50$)
    -Focus SPI header
    -passetter

    expected power gains
    1-8hp mostly top end. may loose some bottom end.


    --------
    :arrow: 2-3'' exhaust:

    expected power gains:
    1-4hp

    anything over 2.5 on an N/A motor is pointless.


    -------------------------------
    Other stuff.

    :arrow: BDR SPI Underdrive pulley ($100)- +8hp (on paper at least)

    :arrow: Remove Power steering if equipped (FREE)- +~5hp and -20lbs or so

    :arrow: Remove AC if equipped (FREE)- -20lbs or so

    :arrow: jeff did a test with removing the crankshaft drag componants. he bypassed the ac and ps and just ran the alt and saw an 8-11 whp increase in power.


    ----------------------------------
    1.9HO valves
    VG-737 valve guides (sealed power)
    99884-8 2.3 Ford double valve springs (crane cams)
    99932-8 steel retainer set for 4 cylinder (crane cams)

    and i used a Crane PowerMax hydraulic roller cam grind number 480531. basic specs are as follows:

    Adv. Dur. 260/268 Lift 429/446 @ valve

    works great together.

    - the 3.8/1.9 HO throttle body will only work if u uncork the exhaust and modify the cable or throttle body and port the intake manifold to its size. the 2.0 throttle body will work with the stock exhaust system and for automatic transmissions. porting is still required.

    - the MAF swap will need the ECU as well to keep the fuel from leaning out at highway speeds. u'll also need to add the EGR solenoid and vacuum regulator found on the firewall and recirculate it to cut off the CEL but it's not as hard as it sounds. 91-92 automatics will need the 94+ ECU from a 5 speed since these autos have a separate ECU for the transmission.

    - the HO header will need to be modified to fit. i've heard bad things about pacesetter headers due to their paint burning off and their 1,3 & 2,4 header design which works like a 4 into 1 header. the HO header is 1,4 & 2,3 which is the true 4-2-1 header but do not go any bigger than the collector shich it 2 inches. the OBX header found on ebay is ok to use with its 4 into 1 design and has a 2.25 inch collector so u can use the 2.25 catback. if u have emissions u will need a high flow catalytic converter.

    - black diamond racing no longer sells the underdrive pulley but escortfocus.com seems to be the only place for them. sometimes they will have them, other times they will be a group buy.

    - for the automatics, a toggle switch can be used to keep the torque converter locked. here's my how to for that https://www.feoa.net/modules.php?name=Fo ... ic&t=67456. a separate transmission cooler is worth the $20 and is better then what's in our radiators. it is a definite must have if u plan to put in a turbo system in. with both of them, u can expect the gas mileage to be the same as manuals.

    - port matching the head to the intake helps with top end power where these engines lack.

    - escortfocus.com has spiral core spark plug wires and dual gaped spark plugs. they help with fuel economy, smoother running engine, idling, and power.

    - raise the compression or HO head swap.

    - if ur looking for a higher final drive ratio specifically for the 1.9, the automatic transmission for the california models and 95-96 wagons has a 4.06 FD. if u want to stick with the 5 speed, the zx2 transmission can work aside from 1 or 2 mounting bolts that won't line up with the 1.9 block. it has a 4.10 FD. sorry, the 1.9 5 speed wasn't made for power.

    - 88-90 HO camshaft is better than the SEFI and SPI camshafts. but it will need to be modified to work with the cam sensor. for the 91 and up, remember that ford changed the cam gear from square teeth too round tooth in april 1991 so swapping the cam gear would most likely be needed.

    Part numbers and prices?

    Thanks marclar!

    Do we have part numbers for any of these? I was hoping to find some stuff at some of the online junkyards.

    Here's a quick and dirty list of where you might be able to pull parts from.
    PM me if you would like to add anything.

    93-96 Mass Air Flow Sensor (MAF) (Unconfirmed to be correct)
    ACDelco part Number: 213-3482 - GM part Number: 19112597
    Google Product Search best price: $78.62
    Rumored to be found on:
    93-96 Ford Escort LX
    94-95 Ford Ranger Super
    94-95 Ford Taurus SE/GL/LX/SHO
    95-95 Mercury Sable
    95-95 Mercury Tracer
    94-94 Mazda B3000 (3.0L)
    94-94 Mazda B2300 (2.3L)

    Notes:
    Various Years ECUs
    Google Product Search best price: $75-200
    Part number seems to change quite a bit.

    the 93-96 is from the escort LX. same with the ECU's. he has some info wrong in that post so i made a few fixes of my own. if u don't wanna pay so much for those items, there's always the nearest junkyard. that's where mine came from.

    You're talking about the larger MAF coming from a 93-96 Escort? I looked up the part number and Google claims the same MAF can be found on those other cars. I thought the list might come in handy for anyone who might be looking for the larger MAF, but can't find a junkyard Escort with one.

    I'd assume the ECU would be a common find. I figured the MAF would be less common. (Easier to take the whole box from a U-Pull than to strip it down.)

    u can use the MAF housing but apparently using the MAF sensor from a higher HP engine advances timing a couple degrees. that's just was i was told.

    yeah, i'd like to change my MAF housing and sensor cuz the housing is slightly bigger, lighter cuz it's plastic, and has 6 wires meaning the IAT sensor is built in.

    ^^that will lower compression which is only good for a high turbo boosting setup

    Actually I completely remove the accessory belt for the test.
    With my G-tech meter I made a pull with the accessory belt on as normal, then removed the belt and made another pull.
    IIRC is was closer to the 8hp increase.

    if they existed, yes. I keep hoping at some point that someone will make one. It would bolt up to the head, but the exit would have to be modified, as well as the EGR port if you run one.

    In what way would the exit have to be modified?

    2nd gen down pipe is straight at the exit, 3rd gen SPI's down pipe angles towards the driver's side.

    How would i go about removeing the power steering? Is it just as easy as takeing the belt off? Or is their more to it.
