Straight from my Helms (Integra Service Manual 1998) page 4-4 and 4-6, Normal conditions and Severe conditions maintenance schedule.... 105k miles or 168k km or 84 months replace timing belt and inspect waterpump. *Asterisk* replace the timing belt at 60k miles (US) or 100k km (Canada) if the vehicle is regularly driven in one or more of the following conditions:1-In very high temperatures (over 110°F, 43°C). 2-In very low temperatures (under -20°F, -29°C). My owner's manual is the same.:fawk:

Which manual are you quoting the 90k miles service interval from?:fawk:

 

i have a 95 GSR, manual says 90k. I just hit 90k so i got to go get that done, should have done it earlier but i havnt had the cash to do it Anyone know about how much the 90k tune up will run? (timing belt, water pump, valve adjustment, coolants etc)

 

Usually the 90k mile service runs a few hundred bucks.

Stumpy - my '92 Helms says to replace the timing belt every 90k miles and then as an asterisk it says "This service is recommended only."

 

Your milage may vary.
