95 tracer 1.9L

Okay i searched for 20 minutes but just want a quick answer from someone who may know, My car has poor throttle response and is very underpowered only when it comes to tough hauls up hills. I want to get a bigger throttle body since the 1.9L is like a quarter with a string. Can a 2.0 spi just swap right over? if not which one is easy to swap, including i can go to a u-pull junkyard and also im looking to do a resonator delete in the exhaust system, Any bad experience with this from anyone? If not im cutting' them and putting straight pipes from the cat/flex to the muffler.

Thanks for reading - Jeff

I have heard the SPI throttle body is a direct swap and is 4mm bigger. I don't think removing the resonator is worth it. Its basically a strait through glass pack anyway. Replacing the muffler with a freer flowing one is a better bet.

i replaced my resonator with a bigger one... a cherrybomb. XD worked for me and fits almost directly in place of it. as far as what matt said, i'm with him, less restrictive muffler is a better bet. and yes, the 2.0 TB is a straight swap, and is bigger. and something even bigger than that is a TB from a 3.8 v6 taurus and the like. needs some minor modding done to make a cable mount but makes an awesome sound and is even bigger than the 2.0 ;)

your mom is the most restrictive part. :lol:

he is right though. i was thinking that since you are upgrading your TB that you had a bigger intake. my bad. lightning is right. :D

I have a "spectre aka Pepboys" cold air intake... But i went to clean the throttle body and you could hear me down the street saying "ARE YOU SERIOUS!?" What a joke haha So im guessing if i had a bigger throttle body it would allow more air flow, more pep? And thanks for the muffler idea, I may just slap a Cherry bomb Turbo muffler on there... Its cheap.

From the EFP website:
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 almost a direct 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.
I would put a better flowing muffler on before I'd screw with the resonator

i just went to the escortfocus.com site to double check what it says regarding the 44mm throttle body swap and it says you would need to drill the intake mounting holes to accomodate the tb and that the throttle position sensor would need to be rewired.but the thing is ,it says for `91-`96 1.9`s to reuse the stock sensor.why then would you have to rewire the sensor if you`re simply reinstalling it, albeit onto a different tb, but the same car it`s already pluged into? and exactly what year 3rd gens. and engines to pull one off of ,`cause i`d sure love to put one on my car for that kind of extra boost ,but i`d hate to drill out my intake and find that it doesn`t work and have to helicoil my intake to fit my stock tb again! the tech department at dynomax recommended an aluminized super turbo #17742 for my `96 lx and amazon.com`s got them for $49 shipped.although i`d prfer stainless myself i love the way the super turbo sounded on all the other cars i`ve had them on and bet it`ll sound pretty good on my `scort.not a big fan of the fart in a can ,baby bottle muffler sound myself,but that`s just me.

The drilling out they were referring to is the porting of the intake manifold so the diameter of the inlet on the manifold matches the size of the new bigger throttle body. All the sensors on your stock throttle body should swap over to the new throttle body so no need to rewire anything.

Just a note on escortfocus.com. Take everything you read on there with a grain of salt. They do stretch the truth on alot of the stuff they say.

that`s my rule of thumb with the internet in general large crystal salt!.but the porting of the tb opening makes more sense than the mounting holes.thanks. is the amount of porting required for that something you could do with something like a dremmel tool or would i need something more heavy duty, maybe a heavy duty drill with some decent grinding attachments?i`ve got a pretty decent rollaway full of tools and variuos hand tools, but i`m not terribly experienced personally with the porting process,though i feel confident that i could, if i knew which tools i`d need and a little more research on the porting process.

if u have a 91 or 92 scort u would need a mass air flow sensor housing from the 93-96 along with the ECU and EGR equipment. use the MAF sensor that's alredy on ur car. i tried to use the 2.0 throttle body on my intake but apparently for the 91-92's the mounting holes on the intake is bigger which is why they were talking about making the mounting holes bigger. yes porting is needed on these intakes with that throttle body and u would have to rewire the throttle position sensor cuz the tang on the 2.0 throttle bodies r about 90* off from the 1.9's. i know cuz i have tried it.

so on my `96 lx i`d have to rewire the tps to make up for the difference in the position of the tang? the escortfocus site says to use my stock `96 tps sensor on the `97-up tb and to rewire it because the tang that turns it is positioned differently,like you`re saying juggalo.it`s been a while since i`ve replaced a tps on one of my `scorts ,so maybe i`m just not remebering how the tps position would relate to the wiring in regards to this swap.from what the haynes manual says you install the`96 tps by turning it clockwise into position with the scribe marks on the tb,and the `97-up tps is installed by turning it counterclockwise.the pictures are fairly clear in the manual and i`d swear that the two sensors wouldn`t match up to the opposite tb.so should the website have said to use the 2.0 tps in place of the 1.9?that would give obvious reason for the rewiring.did that site post a mistake on this?i`m overlooking something or just not sure how the tps works i guess.like i said it`s been a while since i`ve had to replace a tps and i`m more of a parts changer than a mechanic .any edification from any of you patient and knowledgeable folks would be greatly appreciated!

yes rewiring the TPS is required. since u have a 96 the mounting holes on the 2.0 throttle body might be the same as the intake. i wasn't able to fit the throttle body on mine cuz the mounting screws r too big to fit on the throttle body and i don't have any drill bits. but seriously, get the intake mani ported as i was told before. if the HO throttle body that i'm gonna use with my head swap doesn't have a hookup for the kickdown cable then i'll use the 2.0 throttle body.

thanks for the info juggalo.i must admit i`m still confused about the need to rewire the tps though.or which tps to even use for this swap.

You don't need to rewire anything on a '96. I have a '97 tb and the stock tps from that tb on my '96. Also the '96 and '97 take the exact same tps. Works fine with no problem. If you have an auto just make sure you get the tb from an auto '97 otherwise you have no way to mount the kick-down cable. The only thing I can think of is to check the vacuum port on the bottom of the tb. There are two different sizes the '97 has the smaller( you want the smaller to avoid a cel) and a '01 has the larger. I have no clue on the other years. I have 3k miles since the swap and have had no issues what so ever.

thank you very much for clarifying that point about the tps wiring and the info regarding the `97 vs. later tb`s patrick.i assume though that you did need to port the intake to accomodate the larger tb opening,correct? and did you need to drill the mounting holes bigger on the intake as well?
all in all,how would you describe the difference in performance after the swap?

You do not need to do anything to the tb. I got the manifold already ported from another member after he pulled his 1.9 for the spi swap. The only thing nessary is gasket matching the intake manifold and new gaskets. I already had an intake on the car and noticed a little more power in the upper rpms between 3k-4.5k. Took a little to get used to driving the car due to the better throttle response.
