Question '00 2.5l for a'95 2.2l help??

well I think I have all the parts for the swap... but I have a couple of questions I would like to get answered befor I start to take things apart.

#1. The current set up is 95 2.2l with '02 WRX 5mt tranny and running gear including WRX clutch stuff, & flywheel the question is ...will the '00 2.5l SOHC flywheel bolt to the WRX clutch or do I have to get a complete 2.5l clutch set up of a donor car ? (issue is here push vs pull style clutch I have the WRX stlye in the car now)
#2. The car works fine now but because of the WRX running gear the tranny gearing and final drive ratio with the "little engine" make it VERY difficult to drive ... the question here is will the 2.5l make enough difference tho help with drivability or should I look at changing the gearing (390 to 410or 444?) I am hoping to not have to touch the tranny this time around anybody got any insight to this??
#3. What do I need to do about the fuel tank??? some type of sensor or something that requires a jumper??
Quig.

You won't have to change the clutch or anything; it will all go right together.

I'm not sure about how the different gearing feels on each car. All I know is that I loved my 4.11 gears in my RS and my 3.90 could have been a little shorter in my WRX. Many of the WRX swappers enjoy the 4.11 gears with the EJ20.

Thank you Jon for the reply but as I was re reading my post I realized I forgot to put in the most important point... I don't know if the 2.5l flywheel in from a standard or manual trans will that make a large difference??

To clarify a little further, everything will bolt together if you use your existing clutch/flywheel setup and add it to the EJ25.

I did not notice you had asked about the EJ25 flywheel. That will NOT go in there with the WRX transmission. The WRX tranny will require a pull-style clutch and flywheel (they work in pairs) so you could not just add in the EJ25 flywheel. If you want to upgrade to a lightweight flywheel, then just purchase one for the WRX, not for the RS.

Sorry for the slight confusion

no apology needed!!! thanks for the clear info ...this means a much easier swap so far...but can you assist me with the fuel tank question... I have read and re-read all I can and can't seem to get clear info on what is in my 95 vs what the '00 2.5l will require for wiring when it comes to the fuel tank sensors
