sr20det lag, full boost @ 4k RPM
UPDATED LAST POST. PLEASE HELP!!!
I need some help/ advice from fellow zilvians again.
So, long story short, thought i had spun rod bearing, then thought i messed up cam shaft and rocker arms. Took it to shop (Phill @ speed of sound in sacramento, ca) and he basically tore the whole engine apart. Everything interanlly is in really good condition, the problem was a piece of silicon was bocking the oil passage to the rocker arms and cam shafts. That one piece of silicon cost me $550, but atleast i know its all good now.
So b4 he reassembled the head, i bought some used greddy ras (which i think might/can maybe be a factor in this case) and had him installed it. He said the break in time should be about 50 miles, still in break in time, but i notice the car to be lagging ALOT. I notice that when i hit the gas pedal all the way, it will lag until it get somewhere near 4K rpm and then full boost no problem (stock t25)--not getting it to redline. Before, there was no lag but now, its like a N/A until 4K rpm.
My questions:
1st Q: Is it just because the car is in the break in period that it is acting up like this?
2nd Q: Can the ras cause this too? They were a used set of greddy ras. I am thinking they MIGHT just need to re-adjust to my engine and needs a break in time too, but can this be if its lagging at low end and not all the way?
3rd Q: Is there anything else i should check for? I mean i KNOW the turbo is still good b/c no shaft play and no smoking (pretty new).
