1.9L and 2.0L
I bought a repair manual today and it says that the 1.9L and the 2.0 L spi are very similar engines . What makes them similar and isnt the 2.0 like 110 hp's. Sonce the 1.9 and the 2.0 are very similar is it possible to make the 1.9 have as much hp's as the 2.0 with a simple mod.

Re: 1.9L and 2.0L
There are a lot of 1.9 variations, the "hottest" factory 1.9 is the 1987 Escort GT 1.9 HO EFI, it's rated at 115hp.
The next hottest are the 88-90 versions at 110hp.
These motors had roller rockers, tubular headers, and a tuned intake manifold not to unlike the 91 up SEFI style.
So, to answer your question about a 110hp 1.9, it's hell yes!
If you have a 91-96 1.9 with 88hp, a swap to a 1987-90 head (or just have yours milled for the higher compression ratio) and the EGT's stainless steel 4-2-1 long runner header (if it fits on a 2nd gen??) would go a long way toward that 110hp.

Re: 1.9L and 2.0L
thanx for the info . But I am not looking into a head swap I want to keep the engine all 91-96 style. Anything that would not require swaps from other scorts. Why did ford go down in hp with the escort throughout the years. Like you said in 88 the 1.9L made over 100 hp's so why is this engine at 88 hp

Re: 1.9L and 2.0L
The 1.9 SEFI on 91-96 is the base engine.
The 127hp 1.8 is the 91-96 "HiPo" motor
Pre 1990, the base CFI (86hp) and hipo MFI (110hp) were both 1.9 CVH's.
So, the base model increased 2hp, and the hipo increased 17hp. See?

Re: 1.9L and 2.0L
None of the EGT for 85-88 had rollers..only the LX...the 89 EGT had rollers. If you find rollers in a GT and it's not and 89 then someone swapped the heads or motor!

Re: 1.9L and 2.0L
Hi John,
Good to see you on the board over here!
I know you'll add more wisdom to these pages...
BTW, as a plug for John, he's building a BAD ASS 1.9 Turbo 1st Gen EGT that should be a total monster on the street.
How much boost are you going to run in that baby, John?

Re: 1.9L and 2.0L
One big problem is the '91 - '96 1.9 CVH has a 40 mm throttle body and the intake flange isn't much larger, maybe 42.5 mm. You might be able to machine the intake flange to 45-47 mm. Haven't measured it yet. The '91-'96 CVH motors also have a fast-burn combustion chamber that shrouds the valves. Better to use the '97 and later SPI head.
Does anyone know what the throttle plate dia. of the 2.0 SPI throttle body is? Does it use the same type of bypass solenoid valve for the idle as the 1.9 TB ?
Lately I have been thinking about building a 'frankestein' motor for my '95 LX wagon. Use the block, head assembly and exhaust manifold (maybe 2.0 cat as well) and combine it with 1.9 injectors, modified intake, modified tb, plus all the 1.9 sensors and wiring. That way iIwould have the 1.9 computer and wiring running a 2.0 block and 2.0 head. If nothing else, it should ahve better midband torque.
I don't know if this would work. If I have to rewired the engine compartment, I would probably go with a Zetec.

Re: 1.9L and 2.0L
The SPI has a cast alum intake that can be extrude honed
The TB looks exactly the same, although I haven't measured it to compare.
The 1.9 LX MAF is a puny thing compared to a zetec or spi MAF. The SPI has larger openings in the intake because the SPI unit compensates by closing off one of the ports in the head to increase torque at lower rpm's.
DOHC Zetec is the better motor, but the SPI is no slouch compared to a 1.9 CVH (and it would be an easier swap).

Re: 1.9L and 2.0L
Zetec isn't a hard swap, but hold tight... more is in the pipeline for the SPI's. I'm prepping a 93 Escort hatchback and a 88 EXP for installation of 2.0 SPI motors. Cams, udp's, and cam gears are only a couple months away

Re: 1.9L and 2.0L
You think if i took the 2500 bucks a new zetec would cost-and dropped it into a SPI i could meet or beat a slightly done up zetec?

Re: 1.9L and 2.0L
No one answered that yet... I do believe a 110hp SPI can be massaged to 150hp w/o lots of coin.
A header would be a good start, as well as pots (they work on SPI's too) Pots will set you back $20
The 1.9 headers fit the spi's... with that being said you can go to a wrecking yard and pick up a 1.9 HO stainless steel header from a 86-90 EGT and bolt it up...it even has all the EGR hookups! A used header costs $75-100 approx at a wrecking yard (there are bunches of them out here if you'd like me to get you one)

Re: 1.9L and 2.0L
The aluminum LX MAF on my '95 1.9 SOHC LX wagon is eaxctly the same as the aluminum 4-wire MAF used on the '98 ZX2, so it isn't that puny.

Re: 1.9L and 2.0L
The one on my 93 1.9LX hatchback is WAY puny...complete with a screen mounted in front. I'll have to take pics.

Re: 1.9L and 2.0L
and thats where ford (mazda) becomes your friend pick up an rx7 maf or im guessing an exploder maf would also work quite well, swap to the 3.8 liter t/b, mill out the intake mani to account for the larger inlet from the tb, and youll be doing fine

Re: 1.9L and 2.0L
The Mazda MAF's are different...the Exploder's a possibility, but I've heard of some pretty wicked fuel calibration problems occurring.

Re: 1.9L and 2.0L
yes the POTS mod works very well on the SPI.
