New motor ideas, 2.0 liter rebuild (or bigger) Options

[realred914]

2.0 liter four is apart, needs work. would like some performance upgrade while it is being gone thru. thinking of a displacemnt increase. would like ot be able to run the D-Jet still.

what are the piston size options? draw backs of any (are cylinder walls too thin on any of thge big bore sets? is case machinging required? etc..

what are best brands?


also ideas on valve sizes and cam selection would be appreciated.


looking for a modest perfromance boost, but still able to retain the D-jet system
already have the ealry 2.0 liter exhaust system.

let me know what you all have done, and what is available.

thanks

if you want to spend the time & energy you can get some good deals on the needed parts to do it yourself here. off the top it sounds you'll basically need:

20 longblock and the (2) tin peices for 2.0 914 heads
do you have the 2.0 intake runners/manifold w/ your 2.0 d-jet?
have the m.p.s. tuned (for 2056)
bore the 94mm to 96mm jugs (for a 2056)
have decks & line bore checked
jake 9550 or comp. web cam

extras like these are what i did & really worth it in my book:
balance rotating ass.
lighten flywheel to 11 lbs.
get titanium (i think... duh...) and set the valve train geometery
pertronix or simular electronic ignition
