B18C1 With Bolt-Ons Dyno + Questions
Here's my setup:
Stock B18C1 long block
Hondata Intake Manifold Gasket
PerformerX Intake Manifold
Stock GS-R Throttle Body
3" Short Ram Intake With K&N Cone Filter
F1Spec Header (4-2-1 long tube header with 2.5" collector)
Non-highflow aftermarket cat
BuddyClub ProSpec Cat Back Exhaust (2.5" mandrel bent)
This is mated to a 98+ JDM ITR tranny with stock flywheel and clutch.
Here is my dynosheet:

The AFR @ WOT was a solid 13.2
As you can see, the car made 121lbft @ 6100 and 156HP @ 7600 on a Dynapack. Whenever I'm talking about it though, I just say it makes 110lbft from 2000-7500.
The guys at the shop said that the DynaPack reads about 10-12% lower than a DynaJet. I dunno if that's true, or if they were feeding me a line. They claimed to go down the street and run on a DynaJet, then drive back to their shop and run on their DynaPack. Regardless, it is what it is.
I was talking with my tuner about my future plans, and he suggested some changes.
I was going to put P30 pistons on stock rods and run BC4s with matching valvetrain and a mild P&P. He suggested going with JDM ITR pistons instead, running Skunk2Pro2s, and skipping the P&P...just port match everything. He said that he has had a lot of success with the Pro2s on a 1.8L.
Anyway, comments and criticism are welcome...as well as some advice on my build going forward.
Cheers
