the other day i was looking a 420a swap to a 4g63, when i notice it that 420a engine is mount on the left side and the 4g63 is mount on right side .....is it a complicated swap ...for 420a to 4g63 ??

 

Not possible

 

well yes ......
when i saw it .....is a big complicated work .....
but do you think some mechanic can do this job ??
can you give me some infomation why is not possible

 

Anything is possible with enough work.

 

there is alot of fabrication that needs to be done. It takes alot of skill and knowledge and money to have it done right.

 

oh ...ok
by the way ....is the 4 tips platinium borch spark plug ....work fine for my 420a eclipse ??

 

Haha! Funny as hell! "borch" is what you call a Ukranian soup made of beets and beef, tasty stuff when done right.
Bosch spark plugs is what youyou want, may I suggest NGK instead? Check with their catalog and/or e-mail them for info.
Please make sure you spell it right.
