IIGO chip and 276/264 cams

Soooo…it was a busy weekend. I decided to tackle two upgrades I’ve been waiting to do for 2 years. Last week I recieved my IIGO chip from Luis Marques. What a great chip! Pulls stronger and idles better. The AFR’s are right on target. Second, I installed my 276 regrind in the intake and moved the 264 to the exhaust side. The cam came in a 284/276 set – regrinds from stock 248s. Didn’t want to do the 284 just yet because of PV clearance and lash issues, so I started with the 276. I installed both at stock timing. Checked the PV clearance just by pushing on the buckets until the valve touches the piston. On my visual check, I had about 2 mm’s. This makes sense as they’re regrinds without additional lift. …maybe I can add that 284 after all.

That said, this combo really woke up the S14. Much more punchy in the 3000-5000…and a good bump above that. I’ll have a video up this week.

So far, my upgrades are:

- Lightened stock flywheel
- Evo Airbox
- IIGO chip
- 276 regrind on intake
- Evo II cam on exhaust
- 3″ exhaust
- Burns stainless Y-pipe (2 3/8″ throat to 3″ out)
- PLX Devices WB02 kit with narrow band output to DME
- K&N filter

Soon to be done:
- CR transmission
- 2.64 diff
- shim under buckets
- HD valve train
- MAF kit
