protege fs-de vs. probe fs-de

[freekwonder]

im trying to find out the differeces. i suspect the crank/rod/bearings are the same. and the and valvetrain is the same the only differences i think are the ignition. the reason im asking is i found a site that has toga main bearings, rod bearings, and valve train for the probe/626 2.0l and wondering if this stuff will work on out motors.

My current longblock came from a 99' 626 (I think, but am not sure could be a 2000...I hope so!). I hope this answers your questions.

thanks pat. just figured if im building the motor up. might as well do it all up.

in the US, before 2000 the FS used a cast crank... and before 98, the FS in the US used a different block... the head is better in the 98 up FS as well as having solid lifters... the original FS has gone several revisions: in late 93, the head was redesigned slightly.... in mid 94, the CAST crank was revised and again in late 95 and then in 97... the intake manifold was designed for torque and did not have VICS... multiple versions of it has been revised up until a major change in late 95 for OBD-II emissions... the newer intake manifold still lacked VICS and still had long runners.... more minor revisions were made to it until a better non-VICS design was used after the 98 major change... the early FS cams were very mild and designed for torque, the exhaust cam had a distributor drive gear... the cams were meant to be used with HLAs.... the throttle body on the early pre-98 FS's are also smaller (not sure of size).... the pistons went through several revisions, change in 95 and change again in 98... in 2000 the pistons were changed again and the rods were changed in mid 2002 (probably in the advent of the msp)... all the FS motors in 94-97 are the same... the early 93 cam is slightly different but I'm sure the specs are the same... obviously the valve springs are different between the 93-97 FS compared to the 98+... the 98-99 FS cams is revised for solid lifters and slightly improved power and torque... the 2000+ FS cam intake cam is revised for improved emissions while the exhaust cam stayed the same (the protege uses the same cams).... the throttle body was also redesigned in 98 and although there have been some revisions made, the basic design has been in use in the protege until mid 2002 when another change was made again

so... in a nutshell, the 93 FS-DE is s***, and so are the 94-99 (not as bad as 93 though)... if you are to source parts, the 2000+ FS-DE is the way to go... the 2000-2002 626 FS-DE shares the same long block as the protege, but the protege gets a better performing intake manifold with VICS to aid high end flow slightly... and the 98+ blocks allow for the OEM oil cooler to be installed and it may also be stronger than the early blocks

any performance bottom end parts meant for the early FS (probe engine) will work with ours though, just don't grab the OEM crap!

thanks theman. i will grab the toga rod and main bearings for my build up then. so from what i take it. the valve train is completly different.

thanks for the help man. i was hoping you would chim in cause i figured you would know.

the pistons were changed again and the rods were changed in mid 2002 (probably in the advent of the msp!

no s***, i alway heard my 2001 engine is idenical to a MSP.. ANy info of what they did to them??

 

[cortez]

Edwin, you rule!

You should add this to your FAQ.

 

[YP5 Toronto]

Edwin rocks.....

 

[Matthew]

well really hes an asshole but yea, he gives out good info

no s***, i alway heard my 2001 engine is idenical to a MSP.. ANy info of what they did to them??

I heard that the piston crowns were changed slightly for 2002.5, as well as some tolerances on the rods (more corporate influence on emissions tests)...Edwin may need to reiterate on that, this info is very dated...but neither increase performance, and the rods were still cast...same forged crank and valvetrain between 01MP3/ES and 03+FS's...

 

[PaulMP3]

Im wondering if more 01 protege have been blowing motors than 02.5 and up. due to weeker rods.

 

[kcbhiw]

Good info, Edwin. I think that'll go into my researched materials file, heh.

 

[LinuxRacr]

I really hope I don't ******* have a cast crank. :mad:

Whats this site you found that carries the main bearings, rod bearings, and valve train for 2.0L Probe's?By the way, 2.0L Probes are engine code FS02

this is the site http://www.importperformanceparts.net but they dont have any high performance valve train stuff. just the bearings.

The FS02 refers to the casting, not the engine code.

Wow! Neat!

I know this is a very old post but just to let you know that the FSDE that's in the '00 and newer 626 is the same exact motor found in the Protege. The only differences are that some of it's parts were built here in the states (the igition coil pack can be found on the average Ford vehicle and the stock ECU is programed to be electronicly limited to 113 mph) which means that it puts out the same 130 hp/135 ft lbs tq as the Protege. And BTW, From what I know from the dealer, Mazda didn't do anything to the MSP motor but add the thicker head gasket to lower the compression. Other than that, same stock parts, which is why it has low boost from the factory. I wish we had gotten the diesel version of the 2.0L that's offered everywhere else but here so the cranks could be swapped out to hold even more power. But as of what I know of so far, the crank can take some punishment. I say this because there's a BP powered turbo Miata running around in Cali with over 700 hp that's still running the stock crank and I believe he runs 8's (maybe 9's). And just to let you know that the earlier FS series motors have the same duration profile cams as the newer ones (excluding the '00 and newer DE and of course the ZE) which was always 198 intake/ 200 exhaust while the ZE was 210 intake/ 200 exhaust, but with more lift. The trick to getting the older FS to make more power is to get rid of the hydraulic lifters and swap them for the solids, which from what I hear is worth a few hp on the top end. Also, it's cheaper to go with the DE's solid lifters. I believe I was quoted $50 per hydraulic lifter as aposed to either $11 or $17, both from the dealer and either way it's worth it. And as far as FI goes, the best bet is probly to grab a manifold from a '98 and newer 626 and port & polish the hell out of it because the emissions friendly VICS (variable inertia control system) would more than likely block air flow during spool up over a non VICS system. Sorry for the late info but that's my 2 cents.

EDIT, BTW, the heads are the same througout the years. The only difference between the Older distributor'd FS and the coil packed FS is the fact that the DE has a cap in place of that old distributor hole meaning that the ZE cams can be swapped into the olders (minus the exhaust, but it can be taken to the machine shop and have them regrind it to the same lift, but add 210 duration to that and it will pull better with proper tuning)

You might want to edit it again...it's pretty obvious that the 626 engine IS the 626 engine...

also I have never heard anything that the ZE had a different exhaust cam. Someone long ago researched and found that the ZE exhaust had the same profile as all other exh cams in the FS serie of engines.
