Initial timing is more important for emissions. If you are looking for performance I would check total timing. Unplug the vac advance and get all the mechanical in, atleast 3000 rpms and check it. I wouldn't run less than 36-38*. If it knocks at all pull a few degrees out. You will need an adjustable light as there aren't timing marks past 30*.

You know me now I am on Hybridz also, have dropped a 7M in with more power than most RB's and do run the arms.

I have the aluminum front arms on my street Z. The mustache bar won't do anything for handling and the LCA's won't necessarily make it handle any better than stock ones. They are zero compliance and give you the ability to narrow or widen the track or change camber. Caster adjustment is very easy compared to stock. bkelly, If you go poly, don't do it on both side of the TC rod. They don't allow enough movement and it will break the rod. G-machine makes an aluminum/delrin tc mount that is nice.

You can retard the timing a few degrees. I would check your total timing first, not what it is at idle. I would try retarding 2* to start with. Pulling timing will hurt power a little but if you are on the edge of knock it shouldn't take much and the power loss shouldn't be noticable.

You dubbed over the cars sounds:( Goog vid though.

Top End does have a reputation and I see they are living up to it:tapemouth. I hope you get your car back without it costing you too much. If this happened to me, I would post this on all the Z boards. People often forget how they treat people.

This is all accurate. Not second hand. I have wrenched, cut, and welded on Toyota 4x4's as much as I have on Z's. There are 3 different Toyota calipers that will work on S30 Z's. 1 solid rotor and 2 vented. Pick ups and 4runners use the same brakes in a given year, only the bodies differ. 84' is the first year for the 4 runners. I have one of each. S12+8 Solid rotor, staggerd pistons.... Some of the stampings are the same for solid and vented calipers, the only way to tell if it's for a vented rotor is by checking the distance between the pistons, one is obviously wider. 79-85 4x4 (solid axle) ALL pickups & 4Runner use the same caliper (solid rotor). S12+8 on the outside. S12+8 Vented rotor with staggered pistons. 1.5" and 1.15" pistons.... 86-95 4x4 (IFS) ALL models used a vented rotor. Staggered piston calipers are stamped S12+8 on the outside just as the solid rotor calipers. These are found on 4 cyl. pickups and 4 Runners. S12W- Vented rotor with 4 larger pistons..... Later 4x4 V6 4Runners AND pickups have the larger piston calipers. Not just the 4 runners. These have 3 fins on the outside. They are stamped S12W on the back. If you are looking for the non-staggered vented calipers look for the later model V6's. I know for sure all 93's+ with a V6 have them. I don't know when they started though using them though. V6's were available in 89' in both pickups and 4 runners. If you are unsure check the MC part numbers. The later V6's also used a larger bore. The staggered pistons of the vented and non vented work fine with a stock Z car 7/8 MC for sure. There may be a different stamping on the calipers but there are definately only 3 types of calipers and I'm 100% sure on the year and models above.
