Request for information camshafts

[Heryst78]

Hello everyone !!!

I contact you because I want to buy on Maperformance camshafts for my eclipse 4G63 N / A European 146ch.

I need some information before ordering, would it be great if you could answer me?

- Are these trees mounted on my engine? Obviously yes, no worries and no difference between turbo and atmospheric camshafts.
- Do the camshaft pulleys have to be changed? Obviously not because they write "plug and play" editing.
- Do I have to set the motor map after the camshafts have been installed?
- Finally, last question, do you know the lifting of the cams of origin?

Thank you very much

Before we determine the oem cam lift, what year 4G63 N/A engine would it be?

Hi !
It's a 1996 engine

Thanks

Off hand I am not seeing a difference between the U.S./CA and E.U. DSM specs for that. Didn't check JDM.

2.0 DOHC non turbo cam specs all years:

Intake valve opens 26 deg BTDC and closes 46 deg ABDC for a duration
of 252 deg Cam ID mark "A" 1.4 inch cam height
Exhaust valve opens 55 deg BBDC and closes 9 deg ATDC for a duration of
244 deg Cam ID mark "A" 1.39 inch cam height

The "A" should be easily verifiable by looking at the right (passenger) side of the camshaft.

Hi, and thanks for your reply

So basically our original cams are 252 intake side, and 244 exhaust side.

There I wish to pass in 272, obviously I just have to install them and go?
No need to edit the map?

Thank you for your answer

You can very well run them without tuning, but you will see much more gains after tuning.

Ok thanks !
Because now i can't do every thing, i can change cams but don't tuning now... I don't want to f*** my engine because of that
