Boost your charging system with a Toyota Tundra Alternator!

The tundra 4.7L has a 130/150 Amp alternator and it ALMOST bolts right up to your 2JZ.

Simple grind down the top ear by about 5MM and she will bolt right up.

Wiring goes as follows:

The 2JZ 3 pin connector the pins are as follows:
1-L-terminal for charging light
2-IG-terminal for ignition power
3-S-terminal for Alternator sense

The Tundra 4 pin connector the pins are as follows:
1-S-terminal
2-IG-terminal
4-L-terminal
So pin 1 goes to 4, pin 2 goes to 2 and pin 3 goes to 1. The pin 3 is left vacant so use silicone sealant to fill it.
S = White
IG = Yellow Or Black-Yellow
L = Yellow-Green

Supra / IS300 2JZ Shimless Buckets

Its almost a requirement to upgrade from the shimmed factory buckets to factory shimless buckets.   The stock shims have a tendency to fly out of the bucket under high rpm operation.

These are the toyota part numbers for MR2 Spider shimless buckets which are compatible with 2jz.

All measurements of buckets are in mm.

2JZ VVTI Cam Tech

Keypoints

  • Camshaft lobe seperation theory and advantage/disadvantages.
  • VVTI advantages over standard fixed position cam engines
  • VVTI Cam noise with aftermarket cams
  • VVTI Cam gear noise with aftermarket cams / valve springs.
  • VVTI Tuning for best spool and top end power.
  • VVTI Tuning for a quiet smooth idle.

Aftermarket Cam Options

  • Kelford (T202 is a standard 2JZ cam, V202 is the vvti version.  Kelford makes all of their standard cams in vvti grinds as well.  Available since 2005)
  • GSC (S1 S2 and S3 are available in a vvti option as of 2008)
  • Titan Makes a custom Grind 272 vvti cam.  As far as I know its made by GSC.
  • BC makes 264/272 vvti cams… the ramp rate and half durations are very low.  These cams are built for top end power with high duration/lift with low ramp rate
  • Tomei makes some small 2jz cams, in between everyone else and stock.
