Imagine if we had a Y pipe design mid-length or long tube that separated into two separate collectors, crossed at an x-pipe mid car, two pipes over the axle (like a 04 gto) and went into a dual inlet muffler.
We wouldn't have a shitty sounding car anymore, that's what...
If only I knew how to tig...

Yeah, I had 79# injectors that were at 120% at 6500 rpm on E85. Not the pump's fault. The fuel pressure gauge was still reading just fine.
Unless they updated their information from previous instructions, this is what mine read. Maybe they revised their instructions or something. I don't know.

[1] To ensure proper thread engagement and accurate torque readings, clean and re-tap ALL threads in the block. Re-tap only if necessary.
[2] Clean and inspect all hardware prior to installation. Look for obvious defects or shipping damages, plus proper fit, length, and dimension.
[3] a. If cylinder head studs protrude into water jacket, lubricate the block threads of the studs with ARP THREAD SEALER.
b. If cylinder head studs protrude into blind hole, lubricate the threads, nuts & washers with ARP MOLY ASSEMBLY LUBRICANT or 30wt motor oil.
c. Screw studs into the block "HAND TIGHT ONLY".
Note: LOCTITE MAY BE USED IF A PERMANENT MOUNTING OF THE STUDS IS PREFERED. THE FASTENERS, HOWEVER, MUST BE TORQUED PRIOR TO THE LOCTITE SETTING UP.
[4] Install cylinder heads and check for binding or misalignment.
[5] ARP recommends using the ARP MOLY LUBRICANT or at the very least, a good quality Moly Lubricant as opposed to motor oil. This is due to higher friction on the studs as well as inconsistencies in the clamping force of the fasteners when motor oil (or low quality lubricant) is used.
PRELOAD (TORQUE) RECOMMENDATIONS:
(A) Torque values are based on 75% of the fasteners yield strength. Use the manufacturers torque sequence but do not use the engine manufacturers torque specs. Torque the nuts to 70 ft lbs for ARP MOLY ASSEMBLY LUBRICANT (or ARP THREAD SEALER) or torque to 85 ft lbs with 30wt motor oil.
(B) Due to the expansion rate of ALUMINUM, it is recommended that the torque should be 65 ft lbs with ARP MOLY ASSEMBLY LUBRICANT (or ARP THREAD SEALER).

Hey guys just ordered the phelonic spacer from zzp, is there any problems with fitment when it comes to the TVS. I have the Stage 2 belt and 2.9 pulley now and its one hell of a fit. Just wondering if I should go back to the Stock belt of if I will be fine with the Stage 2 smaller belt. Thanks!

Just promise you will go to the dyno. I am sick of all the girls on this site running ZZP S2 cams without knowing what HP/TQ benefit the cams have.
If I had to guess, I would say
375/320
Conservatively...

Slapped a TVS on my 90K mile stock L61 the other day. Limiting it to 13psi on stock pulley until I can yank the car out of DD service and rehab the long block. It is loving it so far, but I need a bigger methanol nozzle, so if anyone is looking to dump off a 10gph nozzle for cheap I'm in the market for one.
As far as the belt fittment I had both the IM spacer as well as the AL blower spacer and the stock length belt would not fit even with a 2.9" pulley. I had to pull the AL spacer and put the stock 80mm pulley on the get a setup that worked.
