Technical engine question

[AZ STE]

Ive got a SR18 engine from a Pulsar GTI (HN14) car. Are any of the internal components compatable with our GTIR engine? ie cylinderhead ,crank,flywheel. Dont want to strip it and find nothing worth having. The unit looks similar although its a 1800cc

the head has a smaller combusiton chamber, i am unsure if it will bolt up to the throttle bodies.

The pistons are 82.5mm

The crank and rods are the sam as an SR20DE (17mm bearings not 19mm on the rods like in the GTi-R SR20DET)

Thanks for the info Nix
