how hard would it be to swap my 1.9 for a 1.8 dohc or possibly the 2.0 dohc? how much more power does the dohc produce over the sohc? thanks

The 2.0 Zetec will produce about 40 more hp than your current 1.9. The 1.8 will produce slightly less than 40, I think they have 127 hp. For the 1.8 swap you might as well order a GTX, you'll need the whole front clip of an Escort GT either way. For the Zetec I am not sure. I think you need to change the motor mounts and possibly the transmission. The SPI swap is much easier than either of them, and is a direct swap, even your old ECU will work with the SPI, but you'll only get about 20 more hp and ft lbs of torque rather than 40. If you go with the GTX, you'll more than double your power... But... It sounds like you need to do more research, I guess. That's what everyone else would and is going to say. :wink:

The two easiest swaps for you will be the ZX2 dohc Zetec motor and the 3rd gen SE/LX 2.0 SPI (sohc) motor.

If you want dohc, then swap the ZX2 dohc 2.0 zetec.

The Zetec motor puts out 120 horses and the GT motor puts out 127 horses. But like James said for you the Zetec motor would be the easier swap.


*EDIT*
I was wrong Zetec puts out 130 Hp.

Actually, the 98-02 zx2 motors put out 130 hp and 127 ft lbs, and the 03-04s put out 130 hp and 135 ft lbs torque. Either way you go with a ZX2 motor you're putting down more torque than the 1.8 GT motor.

That is correct. A 2.0L ZETEC is 130 HP and the 2.0L SPI is 110 HP. So for a direct engine swap, you can go from 88 PH to 100 HP with minimal work. Once you get the 2.0L SPI installed, you can masage the engine with a chip, header, exhaust, intake and you should be able to push it to 120 HP. That is a gain of 32 HP.

Going to a GTX engine would be more work. The 2.0L ZETEC has more aftermarket support. Going to a ZETEC is building for the future.

If I were in your shoes, I would not go with a GTX engine. I would go for an SPI or ZETEC.

info

how much more complicated would it be to do the zetec swap instead of the spi? What could i use/not use or have to custom make?

I'd have to disagree (but it's all a question of opinion), swapping to a GTX would give a lot more potential for power, and once you have a turbo engine, believe me, you have for years of moding ahead of you... unless you'Re filthy rich... :p think BOV, boost controller, bigger intercooler, hybrid turbos, custom manifolds to fit that garrett T28 in your GTX... :twisted:

plus, nothing beats getting shoved back in your seat when you reach 14psi and you've still got plenty past 100mph...

I'd go with the GTX.. it'S a lot of work and money when starting from an LX, but very gratifying...

It's up to him really, hte GTX would require him to buy a whole new car to get the trans and axles and the rest of the front clip, where as a 2.0 SPI will bolt right on and he can save that money for a turbo kit

From what I've gathered in the past: The 2.0 SOHC SPI drops right in to the same motor mounts and bolts up to the tranny from the 1.9L. It can use the same wiring harness and ECU, you just hafta wire in the SPI controller. This is probably the easiest swap you could do. If you knew what you were doing it would easily be a one-weekend job.

The 2.0 DOHC Zetec is another story. It'll fit, but you're gonna need motor mounts, as well as the tranny and axles. If I recall correctly, it should fit in just fine once you've got all the hardware, and then you've just got to deal with the difficult part -- the wiring, which apparently is a huge pain in the ass. You'll also need the computer, obviously.

So it really depends whether or not you're up to tackle the wiriing issue. The Zetec swap certainly would give you more power and expandability, but with the SPI you coulda started the swap this morning and you'd probably be driving your car again tomorrow after spending probably $300-$500 total.

Nihil is pretty much right.

The details on the Zetec:
It must be from a Zx2, it's the only Zetec with compatible mounts.
It uses a different style of fuel system, it uses a non-return system. All 97 and older Escort have a return system. The 1.9 computer can not control the newer non-return system, you'd either have to convert the Zetec to a return system, or swap over all of the Zx2 Electrionics.
The Zetec uses a completey different crank Pos sensor, it's located on the block and the sensor takes a reading off of the back of the 2.0 Zetec flywheel. The Zetec Flywheel/clutch will not fit in the 1.9 bell housing. You could use the 1.9 flywheel, but then you'd loose the crank pos sesnor trigger. That will force you to either use the 2.0 tranny/flywheel, or keep the 1.9 tranny/flywheel make a custom CPS and try to reproduce the correct setup for the computer to read correctly, or just go stand alone engine management.

Where with the SPI swap you could just drop in a 97 2.0, hook up a SPI controller and be on your way in no time, and for dirt cheap-with 25% more power than what you had with the 1.9.

Dang that makes an SPI sound ssssooooo nice!
