Engine swap from a 1.8L to a 2.0L V6

[drew.young06@hotmail.com]

I've been wanting to do an engine swap as specified in the title because my 1.8L is knocking and not sounding to good at the moment.
all i was wondering is that can i keep the same tranny and everything else the same or do i need to buy some new parts also to make it compatible with the new engine?
heres the link to the engine if i helps any.
thanks.

You would be better off getting a KL-DE 2.5 from a MX-6/Ford Probe , 626 as it is a drop in replacement for the MX-3 1.8 and you would also gain 30 hp or if you have a little more cash to spare try the KL-ZE 2.5 and gain 50-60 hp and it also is a drop in replacement.

I've been looking at the klze swap recently. but ive been told there needs to be some slight manipulations to the installation of the engine rather than just unhooking everything taking the old engine out, and then putting the new one in and rehooking everything. im not sure if this is true or not.

the only manipulations I know of are 1. Make sure you get the Curved neck intake manifold KL-ZE the straight neck would hit the brake master cylinder set-up 2. reuse the 1.8l MX-3 top coolant inlet as the KL-ZE outlet is angled different and has 1 less sensor fitting 3. the distributor on The KL-ZE has an external coil while the MX-3 has an internal coil. 4. The nipple on the Intake Manifold that is for the line that comes from the vacumm chambers feeding into the "T" leading into the two VRIS vacumm actuators, is located generally in the middle in back of the Intake Manifold , that nipple is now on the passanger side of the Intake Manifold, just to the Left of the #1 Vris Vacumm Actuator. 5. On the Front of the Intake Manifold, there is only One Nipple. Whereas on the MX-3 Intake manifold there were two. One is for the Cruise control, the other was for the Fuel Pressure Regulator Control Valve, the fix for this is simple, where you only have one Nipple simply use a "T" like what is on the vacumm lines leading into the Vris Acuators. 6. To get full potential out of the KL-ZE get a JDM PCM but it will run fine with the MX-3 PCM. and 7. reuse the front motor mount off the 1.8. and as an added bonus reuse the 1.8 flywheel on the KL-ZE as it is lighter.

i currentyly put a 1.8 longblock in my millenia cause my 2.5 took a poop.I reused everything but the block and heads,but it seems to idle weird it raises to 2200 than drops to 1000,could be a bad sensor they sat for 3 months.Other than that it all works..(i also reused the 2.5 ecu)

Thats actually taking a step back. The 1.8L only put out 130 hp while the 2.5L put out 160 -170 hp. That idle issue is your Millenia telling you its not happy.

using the 2.5 ecu with a 1.8 is the reason you are having issues. the vam/vaf between the 1.8 and the 2.5 are different as well as the engine management.

I'm looking for a KL-ZE lump. I've seen some ford probes that claim to have 200bhp standerd. Is the KL-ZE in some ford probes or can i only get the lump from japan?
Nice to know the 1.8 flywheel will fit the 2.5. Thinking I might change the tranny aswell, cruzing at 6grand aint funny! Take it the tranny is just standerd mx6/probe? Do you know what ECU would be best, and where to locate? Might need to cut down the 6 branch manifold to fit, would be criminal not to fit them whilst it would be so easy to do with the engine out. Would you happen to know options for LSD? Any help much appreaciated
Many thanks,
George.

The KL-ZE ecm is the way to go along with the KL-ZE VAF it will allow you to get the full potential (200 HP) out of the engine. The KL-ZE is all JDM so you will have to get in contact with an importer to get it. The ford Probe and MX-6 came with a KL-DE (160-170 HP) it has lower compression , different cams , heads and intake than the KL-ZE . If you can only get a straight neck KL-ZE grab the intake off the Millenia 2.5 it uses a curved neck KL-ZE intake. The tranny from a V-6 MX-6 , Ford Probe , 626 and the GS MX-3 all use a G-Series Tranny. As for LSD your only cheap option would be the mazdaspeed protege Diff. which will fit basically all G-series manual trannys.
