• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

seeing 7*+ of KR with conservative mods... Any suggestions??



I've been running with chips for a while. I'm making an assumption, but I feel a well thought out assumption based on my knock issue from the beginning of scanning that I've been running with a chipped piston for the entire time I've owned it. 30,000+ miles.
I'm going to put a piston in it against the advice of several on here; I plan on making sure that my clearances and torque specs are done properly.
The car is in the garage on jack stands right now; just need to find time and motivation in my currently busy schedule.

Best of luck with the build. Would love to see some pics of what the piston chipping looks like if you get around to it.

I have to to change out my boost bypass actuator this weekend (stock one went bad over these past two weeks). Once I get that swapped, I can try a few pulls and see what the logs tell me.

Rest of tune-up done besides ignition?

Engine/trans mount condition?

Knock sensors in '97's don't normally care as much.

Get rid of the TB spacer. It's crap. Blocks off coolant flow, causing the rear bank to run hotter.

Too add to this you can run the block if you grind the passage in the LIM to allow coolant to pass through.
 
I may just pull the spacer off this weekend. Sounds like it really doesn't do much for me after all. Although, it is tapped for Meth, which I was considering using down the road.

Maybe I can dremel out the portion of the spacer which prevents coolant flow???

Look at above post #47
 
Ahhh. You mean dremel out the spacer on the bottom to allow coolant passing. Got it. I will probably experiment this weekend on it.
 


You'll ideally want to pull the LIM. Take the two bolts off the cover you'll see a little divider wall. If you dremel that wall down coolant it will easily flow to the rear head.then just use whatever method to plug the coolant holes going to the TB.
 
Removed the TB spacer this weekend completely. Just figured I wouldn't hassle with dremeling anything and ruining a good LIM, or good TB spacer.
 
It would be really hard to **** up the coolant crossover job for the LIM . once you unbolt the cover you'll clearly see what needs yo be done...not to mention the LIM that are factory desperately need to be port matched
