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

Several years ago I proved that the capability of the stock FI system to be easily tuned for more performance was 2056cc and 115HP. Over time I have made small tweeks to the camshaft to allow 120HP from that same engine, but that seems to be the maximum.

If you want to take risks and spend time effort and money to attain more power from a bigger stock FI equipped engine you have that option, BUT be forewarned that success probably isn't in your future.

Fact is that going bigger with the STOCK FI will generally net LESS power than a properly sized and outfitted engine. Bigger isn't better if you want to drive your car instead of working on it.

Cam, CR and cylinder head preparation are all much more critical when using the stock FI arrangement. Most cams simply will not work.

115-120 REAL HP is a HUGE boost to the engine's power. The biggest gain is in the engine's RPM range and how it pulls over a much more usable and broader portion of the tach... Thats what makes the car quicker, faster and more well behaved.
