ITB balancing

[zaq123]

was the car sitting for a long time? Some report that the return inside the tank itself gets clogged if car sits for a long longtime with old fuel. Go under the left side of the car, disconnect the return...

Thank you digger. That's pretty easy to do. Also If I remember correctly when throttle pairs were in my hand, some had visibly noticeable plate to bore gaps (on sides of the plate shaft ) which looked...

I spoke with Rama and have him watched the video. He said he can send me the throttle after the return but also he said that since I'm running vacuum, the difference I have is not that bad for the idle...

Rama said don't mess with plates so I took his word for it. No compression test yet, still putting miles on the engine to fully break it in....

my understanding is that at WOT, this balancing error is really not that critical (unless of course it's a huge difference). But for good idle and off idle throttle response it is. I don't have any issues...

valve lash was checked too many times due to me trying to stop that valve cover gasket seepage. It's not laking but sweats oil overtime just enough to annoy me. Originally syncd ITBs with ICV blocked...

and what he said about the size.. Right size? That line is after FPR , the return to the tank line so there is as much pressure as in the gas tank, almost none. Unless your return is blocked somewhere...

[zaq123]

As a precaution, Id put a pressure gauge and double check your pressure (to test FPR and for any blockages in the return to the gas tank)....

Post edits don't work again on this forum.. But just to add, my cam is Schrick 284...idles good enough for that cam?...

I like boring valve covers. This is brand new one, got it when was still available. Still can't get it to seal so everything is bone dry. Getting a little oil sweat on the gasket joint, not leaking so...

I 've been putting some miles on the car with new tune and dialing idle as best as I possibly can. Decided to take of ITB plenum to check if the balance is still ok from what I initially set it at. I...

I really believe Z3 trailing arm OEM design is all most e30s really needs. Designed for S50 so should be able to handle some abuse, the same for the subframe design. You know how trailing arms become...
