how is the driving experience with the new 2.0? despite the drop in displacement, you gain lower centre of gravity and better rod ratio, high rev smoothness??
@Tyler smith yeah mate. I used the 2.3 ecu, inlet cam, crank pulley then had to make a bracket to move the crank sensor closer to the crank pulley. The 2.3 crank pulley is smaller diameter and has a different tooth count to the 2.0lt
Was the lf originally a vvt or did you convert it to vvt using the l3 vvt parts like cam and solenoid and also is it still running the l3 vvt fuel set up or running lf injectors and fuel regulatior and pump?
Yup the LF was originally vvti, I just swapped over the cam shaft from the L3. The camshaft had a different trigger wheel for the cam sensor. I uses the L3 injectors and rail, inlet manifold etc. Everything the was matched to the L3 ecu was used
Thanks for the quick reply genius work u have done there man i have a mazda 6/atenza 2004 was originally 2.3 vvt l3ve motor with 4 speed auto but has had a lfde 2.0 non vvt put in it running the original l3 4 speed auto transmission wanting to convert the lfde to vvt by using an l3ve vvt head but il also have to swap the crankshaft and currently having issues with the 4 speed auto going into limp mode whenever i try use manual shift mode and also no speedometer signal a/t light comes up and check engine and i get dtc for "vehicle speed sensor circuit malfunction" have checked the wiring and rhe sensor and theyre all fine
@toddbrown5988 I think from memory they have a speed sensor on top of the trans that is known for failing, not sure if you have checked that? Is it still running the original ecu for the car?
Yup ur bang on there man on my gearbox which is the 4NES 4 speed from the 2.3 vvt that was in it they have a speed sensor in the differential on the gearbox and also a turbine input speed sensor on top of gearbox think that reads the speed of either the input shaft or torque convertor its runnin the ecu from the donor car which the previous owner had no details of iv gathered from info on the net that is a 2007 lfde non vvt motor because the engine number starts with lf4 but i may be wrong as it has an LF78 18 881F ecu which is from a 2004 lfde 4 speed auto whereas a 2007 lfde would have a 5 speed auto fnr5 transmission the guy that put it in is pretty clueless iv been going through the car checking every single wire cos he missed some out some times it comes up with dtc for no communication with canbus or abs something like that its motor wont run on the l3ve 2.3 vvt ecu because the lf i have isnt vvt like urs id say the fact theres no vvt it would have been confused lol he was also running the 2.3 vvt l3 2 stage variable intake and never tweaked that coolant pipe like u did and the hose rubbed against the back of the intake and split (by the way how did u tweak that pipe? Just twist it or something?) And the 2.3 crank is alot bigger and has balancing shaft or something like that on it i think that was to do with the longer stroke also reason why the l3 has a taller deck that the lf to accommodate the extra stroke to make the extra 300cc of displacement over the 2litre lf id say they done that because it would have been easier to redesign the block to still be compatible with all the parts from lf and l8 all 3 motors are almost identical internally i think apart from cams and timing chains when it comes to vvt versus non vvt but dont quote me on that lol iv downloaded a couple of workshop manuals from online one has over 2000 pages and covers all 3 l series motors the 1.8 2.0 and 2.3 il b fitting the correct intake for the lf motor when i put it all back together currently have it apart for that hose issue while waiting for the part and removing old aftermarket alarm wiring and fitting a new alarm and sorting engine bay wiring
HI. Thanks for your videos. I swapped also a 2.3 for a 2.0L. mine is mazda 5 2007. I changed the crankshaft pulley and the camshaft for matching the ckp and cmp sensors. the time kit is set on right. But the check engine light is on and sending the P0012 code. Camshaft position over-retard. is there another modification I forgott for?
How you do the crank sensor
Can you do the opposite? change from 2.0 to 2.3?
Hello. I have a mazda 6/atenza 2.0 with LF Engine 2008 model. Can I swap the LF with L3 engine?
how is the driving experience with the new 2.0? despite the drop in displacement, you gain lower centre of gravity and better rod ratio, high rev smoothness??
In all honesty mate, if you didnt know it was a 2.0lt in there, you wouldnt know any different haha it was pretty much the same
Did you use the 2.3 ecm mines not getting spark with the 2.3L ecm
@Tyler smith yeah mate. I used the 2.3 ecu, inlet cam, crank pulley then had to make a bracket to move the crank sensor closer to the crank pulley. The 2.3 crank pulley is smaller diameter and has a different tooth count to the 2.0lt
@@accelerateauto374 because mines getting fuel just no spark still could that be because of the crank sensor
Inlet cam is front cam right?
Was the lf originally a vvt or did you convert it to vvt using the l3 vvt parts like cam and solenoid and also is it still running the l3 vvt fuel set up or running lf injectors and fuel regulatior and pump?

@toddbrown5988 also, what's different with the crankshaft?
