I was gonna say. My integrals needed some crazy shims (see my build thread) but no grinding.
Yea maxx so true, at the time I bought a whole bunch of shims from Mazda. In fact, I have a few left over still in there plastic bags.
Wouldn't you agree these turbo sticks are the best you can buy for boosted FS-DE's, especially for those who are using decently sized turbos??
Before I installed and tuned the Integrals I was running a PnP, 3 angle valve job cylinder head with my "old" school Garrett single bearing 61mm T3/T4R V-band(0.63 A/R)turbine
<- the same compressor size as a GT35R minus the dual BB technology with a V-band(0.70 A/R) turbine. Boosting 16psi+ on the stock cams was fun, however, the engine lost steam around 6500rpm. I was surprised and disappointed.
Long story short, a mazda247 member's boosted protege was totaled, so I paid for his Stage II Speedcircuit cylinder head that Dino had already had finished, however, the Stage III camshafts took a little extra time to finish. A few weeks go by and the engine was put back together with the new parts and after a very long day of dyno and street tuning the speed had transformed into an entirely new beast. At this point I was so excited to drive it. After all the hard work, money, and patience thankfully my power band grew quite a bit. Luckily, I didn't lose my low rpm stock cam pull, in fact below 3000rpm the built stock bore FS-DE Wiseco 9.0:1 pistons put down more torque versus the stock cams at the same psi.
I literally went through a half tank of gas on the I-4 highway banging through the gears boosting 15 than dialing it up to 20psi for the hell of it _LOL _ The point of this long post is that I was safely revving to 8000rpms all day. The motor ran like a top, was stupid fast, and sounded ridiculous idling and absolutely incredible at WOT!
I'm on photobucket right now looking for a video I took of the MSP idling. Please understand though that this video was taken before we installed a properly working throttle body. For some weird reason my original TB was stuck/broken. Also note, my Haltech E6X was street tuned so I could drive around before the TB arrived the next day.
