Thanks Colombo. Your IPP block will be 8.8:1cr while mine will be 9.5:1cr so it won't be a perfect comparison. My 3.12 pulley will already be overspinning my Si's maximum 52,000rpm by over 1,000rpm. I'm thinking a 2.87 pulley would overspin it way too much. I was previously predetonating with my 3.12 on my stock block so my tuner had to pull back a ton of timing up top. I may even drop down to a 3.25 like unvmyg35 did if I start pinging. Remember I'm tuning for California 91 octane only. My slightly lower cr and ceramic-moly coating should help a bit with the pinging.

Well, the good thing with bigger pulleys is more belt wrap so you'll have less slippage to worry about

More parts. ATP Garret intercooler and a bunch of massive intake filters. The best way to find the largest intake that will fit is to try them all!
Thanks 350zhp306 for the idea. I'm thinking only the two smaller filters have a chance of fitting above my crash bar though.

all everyone is doin is just marking up parts ordered from nissan. nissan doesnt sell that straight coupler, thats why places like CZ dont include it.
a few mins looking up part numbers saved me quite a bit of money over ordering a "kit" from one of those vendors.

Latest update is that there is no update. Rebello still hasn't finished the motor. The car has been sitting at Z Car Garage for over 3 months and have been told 3 times that the motor will be done at the end of the week...that was almost a month ago. I can understand delays and I'm sure it'll be worth the wait...but I just wish I could have been given an honest ETA from Rebello. Nothing I can do now except keep waiting.

You put it together Backwards.....
The Two 1/8" thick small diameter spacers go on the shock tower side between the suppled metal brackets.
The 5/16" thick large diameter spacer goes on the Blower side.

Looking good, going to have to put my order in for one of those radius rods here soon. My build is starting to come along at a better pace now and she will be getting her new engine dropped in soon.
Hope your build gets some love and attention, I can definitely relate with the anticipation.
