Ace_t Neutral Newbie January 20, 2004 Author Share January 20, 2004 what's the idle rpm and rpm at 100kmh ? think u should have more torque at the low end, coupled with yr 421 extractor. Have you done a compression test to see the results after this overhaul ? Link to post Share on other sites More sharing options...

Ace_t Neutral Newbie January 20, 2004 Author Share January 20, 2004 if u got the diameter, then I got the manual to check the capacity. Link to post Share on other sites More sharing options...
Vidz 6th Gear January 20, 2004 Share January 20, 2004 din know.. as long inspection don give me problem can liao... but just a little only.. cos actual is prob 1595CC so slight oversize is about 16xxCC Link to post Share on other sites More sharing options...

Saaber Neutral Newbie January 20, 2004 Share January 20, 2004 you should be getting more torque thru out the rpm range with more cc... Link to post Share on other sites More sharing options...
Vtim 3rd Gear January 22, 2004 Share January 22, 2004 yoh ACE, long time no see you at meetup the pressure that they measure should be in PSI lar, if BHP then you car will be at least 150 x 4 = 600 BHP liao 1) I'll go for top overhaul, looks like cylinder 2 & 4 are having their piston ring wearing off (normally the case for high mileage engine), if you intend to drive it for another 3 to 4 yrs . Top overhaul shouldn't cost that much as $500 - $800 as your's is a inline engine so don't need to "drop" engine for a top overhaul job shouldn't be more than $400 IMO unless it's a boxer engine (horizontal-oppose) than it'll cost at least $180 - $200 just to "drop" the engine alone 2) Complete overhaul will be good if you intend to drive it for another 5 yrs & above, should be max about $800~$900 for the job. 3) If it's same capacity as your current ride, shouldn't be a problem but still have to go thru' gahment, else you can do like what other's do 4) Do it now before it gets worst 5) Don't think this is an viable option for you Gong Xi Fa Cai Link to post Share on other sites More sharing options...
Vtim 3rd Gear January 22, 2004 Share January 22, 2004 what about a new engine drop-in ?..price n availability will be made known after CNY. it's aways a good option, only thing is.....you know what Link to post Share on other sites More sharing options...
Vtim 3rd Gear January 22, 2004 Share January 22, 2004 Compression reading is in psi.11.7% difference in compression reading is acceptable. Get your mechanics to do a wet compression test to determine the compression leakage is via the rings or valves. PS wet compression is carried out by pouring into the weak cylinder about a tablespoon of engine oil to improve ring sealing effect. If the reading is still the same then the valves are gone. If the reading goes up then the rings(and the piston cylinders ) are wear out. Hope this helps I learn something new today, thks Link to post Share on other sites More sharing options...
