Yeah a crack in the old dried out stock hoses is very possible, as is a loose clamp, or even a crack in your IC. Less likely would be a bad gasket in your intake parts. any one of these could cause a boost leak a higher than stock pressure, and indeed may have been caused by the excess pressure...
If the stock gasket is 1.37mm, then the HKS is already to thin for stock surfaces. Since you have already machined the head, (and hopefully the block as well), You will need to get a much thicker gasket to maintain the correct compression ratio, or you will get detonation issues. And if you...
I was hitting fuel cut with the stock CT26 and two washer wastegate shims, so yeah it sure seems like you got fuel cut issues. Pull out the shims for now, until you can get the necessary upgrades to support the increased airflow. That's what I had to do. Now my car runs fine, has seven pounds of...
Just an FYI! It's an AFM, not a maf. I'm just telling you this, so you don't get reamed a new asshole for calling it the wrong thing. I see that you rewired the AFM connector. The intermittent nature of your problem seems to indicate that the plug is loose, or the contacts are dirty. I've seen a...
Follow the troubleshooting instructions in the TSRM. It will tell you how to test any component that might be causing your problem. For example: http://cygnusx1.net/Supra/Library/TSRM/MK3/manual.aspx?S=IG&P=15 Do it now before someone tells you to RTFM!
+1 on the fuel injector cleaner. Shit happens, all the time. Anyway, it's good to do this periodically, and usually helps to clean deposits on the valves as well.
OK, I will state right off that I'm not a plug expert. My JDM engine had a set of Denso Iridium's in it when I got it almost four years ago. They were in good shape, and since I had not heard anything bad about Iridium plugs I decided to use them. I never had a sparkplug issue in the almost...
I've been wondering that too. I had two stock gaskets sitting on the garage floor, but I went through the trouble of cleaning, and reusing the HKS Stopper from my stepson's abortion, as much for that reason, as for making more power.
Though I'm telling the truth about doing this, I would think you could tell by the post, that I was just playing, and would not seriously try to get someone else to do it this way.
