I am going to be building a GSR swap. This is going to be my first engine build so any suggestions are great. What do you guys think?

B16 DPR P&P Head (already have)
Manley Valves (already have)
Skunk2 S&R (already have)
Skunk2 Old School Intake Manifold (already have)
ARP Head Studs (already have)
Skunk2 Pro1 cams
STR Cam Gears (already have)
TDM Hytech Rep Header

GSR Block
81.25 JDM P30 Pistons (already have)
Stock Rods-ARP Bolts (already have)

Fujitsubo Exhaust 60mm (already have)

Transmission
Exedy Stage 1 Clutch
JDM ITR Trans 4.785 FD (already have)
Resurfaced block/head deck

What should I change/add. Not really sure about the TB, IM, or Air Intake.

 

What part about the engine is "R" ?

 

Anything from a stock TB to a 68mm is fine. A 3" AEM Cai is proven but if you have the time and want to install a custom tuned length intake, that will be "best". Your intake manifold is fine as well. A 70mm exhaust or larger will also make more power.

 

^ what he said.

Also you will need a good tune!
