pressure leak maintnance, fuel cut

[zacksgsx]

Well, we were getting lots of hesitation and hitting fuel cut ('the invisible wall') at about 3500 rpm in 3rd, just as the turbo was kicking in. The car is a 97 GSX, all the normal bolt ons, stock T25, 109,000 miles.
I researched the fuel-cut posts and learned we needed to check for boost leaks first. We found several and basically took everything after the turbo off, inspected, cleaned the mating surfaces and tightened them back down. Runs great now. Buzzes right up to 5800 rpm no problem( I haven't tried it higher than that) It is a factory set up. Is there a recommended maintnance proceedure at which point you should automatically replace everything in the system that might leak (hoses, clamps, flanges, etc)? Would recommend upgraded parts to replace these item? I don't want to run into fuel cut again! Thanks for any thoughts. TP

It would be nice to upgrade all those hoses and clamps etc. since it is an almost 10 year old car, but not necessary. Just run through and see what hoses look like they are getting worn, tug on hoses and see what lets loose and replace those clamps. I had a turbo coolant line clamp the blew off the hose since it was bad, ended up leaking out all my coolant and was overheating pretty bad, but luckily not long enough to damage anything. http://members.shaw.ca/dsm.1000q/Engineprimer/ that's a virtual view of the engine bay, you make want to look at that to get a bearing on what hoses are what. Hope that helps.

If you don't already have a manual, you should get a Haynes or Chilton. They give the service limits and maintenance schedules for a lot of stuff.

You can also get the shop manuals on CD. Used to be able to get them from manualcd.com, but last time I checked, they redirect you to ForcedPerformance who apparently carries them. They're cheap and are scans of the mechanic's manuals.
