Any Other Toyota Coils Fit Ls 400?

[Dan1]

I have ( think) traced my running prob to the top coil / or maybe even the left dissy?? was thinking I should get a coil and try it/? does any of you experts know if any other cars have or share the same coil,,, also does anyone know/ guess what the compression reading for an ls400 with 110k on the clock??

thanks guys :shutit:

Hi

Knew I had read something some where, this is from Lextreme

The 1UZ is effectively operated as 2 x 4 cylinder engines that are ganged together. It utilises a RPM sensor located behind the bottom crank pulley, with a distributor mounted on the front of each cylinder head, directly driven off a camshaft. The RPM sensor doesn’t really like getting submerged. Each distributor generates a cam angle signal and distributes the spark to four of the cylinders. Each distributor supplies spark to two cylinders on the opposite bank and has its own coil and igniter module.

The igniters are normally mounted together on the inner guard and their housings must be well earthed in order to operate correctly. The wiring for the igniters and AFM shares a common loom and is often cut when engines are removed from the parent vehicle. The V8 utilises two main igniter types, which are readily identifiable by three large digits printed on a metallic sticker on the unit. The correct igniters are either marked ‘123’ or ‘201’ and are relatively common on Toyota 4 cylinder twin cam performance engines from the late 80s onwards such as 3SGEs, 4AGEs etc. Note that you need a pair of the same igniters and that the 123 series have different plugs to the 201s.

The VVT-I engines run a direct fire system with an individual coil directly on top of each sparkplug.

Looks like the igniters are common but the rest is purely LS400
