DC5 Technical Problems/Issues

[lightningfield]

Post any problems of your beloved DC5 here. Perhaps experienced owners can share their thoughts/opinions with you. Please keep discussion focused as per thread title.

In all honesty, theres not much problems with these cars, but anyhow, maybe i can start the ball rolling and others gurus can further elaborate and add on. These problems have some commonality with EP3s also. Some of the problems seen so far:

1) Synchros crunch when hot... (but it seems its the pfls that have this prob more)
2) Undercarrige bump from exhaust flex when wet...
3) Hydro engine mounts kinda weak (DC only), but in general i think the mounts are a bit of a wus on these cars...

4) sensors keep dying , especially TPS & 02 sensor
5) water retention for stock pre-facelift side mirrors (car wash anyone?)

Hydro mount on p/s side definitely needs to be changed to stiffer mount! coz it wont last for years. but guys have u seen FD2R mounting on the p/s side? it has the hydro mount, But on top of it there's another mounting attached to it n connected to the body. sorta like ETD. looks way tougher than EP/DC.

yeah, that particular connection, according to Chris from Pentagon, acts something like an engine dampner, stops engine from too much movement during revving and accel off.

too bad our dc5's dont have it , we've gotta upgrade the mounts

buy a big absorber n do adapter n plug in to the engine lo..haha..less shock n vebration...hihi

just sharing some knowledge... happened 2 me..
problem: forgot 2 remove my -ve terminal while went out 4 o/station.. battery was weak.. had 2 jump start.. idle was ok then after 5 minute it starts 2 jump from 2K-3K rpm...
solution: drive it & make sure yr vtec open 4 the 1st & 2nd gears (rpm over 6K rpm).. another solution just drive it 4 10-20 minutes.. ecu will reset automatically (i meant back 2 normal)... cheers..

i think only:-

1) pfls have it more often cause it is older and need overhaul. Or it could be the oil breakdown when hot.
2) common when you change after market exhaust. Solution change engine mounting or ETD and must change harder exhaust bush
3) Yes weak. Need mounting strengthening once I/H/E and ecu done.

YEs, from factory FD2R mount are much stronger than DC5 and FD2R does not need any attention on mounting till you break 205whp mark. Once pass 210whp mark engine rock is very significant and a solution is need and we have found the solution for all FD2R that break 210whp now. :)

Regarding Syncromeshes:

Apparently the PRE FACELIFT dc5's have just regular steel syncro's between the 4-5-6

but the face-lifted ones have been upgraded with carbon-something synchromeshes in the 4-5-6

I can't remember the exact details now, but run a google on it , the details should be there.

 

[minivan]

Yep true...
Now, can pfls use the carbon synchros??

 

[Vagabond]

i believe pre-fl's should be able to use the carbon synchro's as the gear designs & ratios for the jdm pre-fl & fl are inherently the same.

 

[minivan]

Yeah true vagabond bro, should be the same as only the materials should be different. Unless honda made any minor adjustments to the carbon ones...

 

[Vagabond]

heh heh , honda only made major gear revisions for the USDM Acura RSX pre-facelift to post-face light.

nothing major for the JDM versions.

5) water retention for stock pre-facelift side mirrors (car wash anyone?)

the same happens to new facelift ... and its like LOTS of water coming out from the mirrors if u drive after a car wash.
