Anyone compression tested their B18C2/VTi-R's?

also is this a C2? and have you ever had a rebuild or anything?

^^ my thoughts

not sure why i posted it without doing more research... >_>

Any mech can do this? Mite get mine checked out

assuming this is a type R engine those are some very health numbers my friend!

anyone else got a B18C2 w/ numbers?

I would reccomend doing a Leakdown test as this is a lot more accurate to how healthy your engine is.

The leakdown test will tell you if your rings are leaking or head is leaking via valves etc etc.

Different motors have different compression

for e.g. 150-160 on a lower compression motor could be healthy as **** where as for a b18c that would be shit and showing huge signs of wear and tear.

yeah that is correct. every different engine is meant to run a different compression as different engines have different compression ratios.

in response to leakdown tests, it is a good idea for further investigation if you're getting low compression numbers, but you need a compressor, leakdown tester (online order) and a fitting to link the hose to the spark plug holes.

or you can pay a shop to do it. however, I don't know about you guys but personally I don't trust any shops here in canberra for shit. always do a shit job or give my car back damaged or both. also there are HEAPS of dodgy mechanics (in canberra at least) that will tell you false things to try make money off you.

if it ever comes to a point where I need a leakdown, I think I will try source the compressor, tester etc. myself. but right now I don't think it's necessary.
