Hello, I have been offered a Pair of NEW c27a heads to go with my NEW C27a block I have. However the same person also has:
For sale. Brand new, unused 825 (Honda) engine
Used as a test bench model, its never been in a car and comes complete with all ancilliaries such as starter, distributor etc. Its obviously a rare piece.
The 2.5 is a good engine...there are some slight differences from the 2.7 but most obvious is the lack of a Variable Intake Valve plate and the 2.5 uses vacuum advance at the distributor to adjust timing...
Actually I would stick with the 2.5 intake manifold for the time being and see about porting it out as it (anecdotally) flows better than the 2.7 manifold due to the lack of a bypass valve plate....
I'm still trying to get my hands on an extra 2.5 manifold to do a complete comparison...
had a rough look at the engine. looks ok, dusty but is actually new. was intended for an auto. the intake manifold is way different, biggest things i noted were, design of fuel rail and breather to plenum. the throttle body has somthing sticking out into the moving air. and the ignition has a lot more rom to play (more advance)
i got the heads tonight, got home and opened them up, they are both front heads however one has all valves and exhaust rockers the other has no valves or rockers. still happy as i can play at gas flowing the empty head.
