20V on MS2 idle issue

Hi I'm running my 20V on a DIY Autotune PNP MS2 in an AE111 Levin. It has a random stalling issue where sometimes when I press the clutch the revs drop so fast the engine stalls, this is not helped by a slightly sticky C56 gearbox. Most of the time the revs will drop, slow down and settle to idle bu...

Re: Persistent COR and gauge problems, 20V swap

I don't know about the US cars but the Euro and Jap cars have a Green and Red wire that comes out of the COR and the ecu grounds this wire via the pin FC. Also the +B supply for the ecu comes from the engine bay relay box through the engine harness and into the passenger side junction box, if you do...

Re: Anyone Techno Toy Tuning T3 camber plates ?

The T3 top mounts come with a separate nut and sleeve to go into the bearing unlike the 1 piece Cusco nut/sleeve. You might have to relieve the strut top a touch to get the other bolts in, the gold bearing housing is probably universal and dictates the sliding area of the red plate. So without using...

Re: What variant of 4agze do I have ?

First check is big port or small port, look for the oil return from the head at cyl. 4 to the block just above the sump on the intake side to identify a small port.

Cut the end off the lead that's in your hand and crimp on a ring connector and ground it to the chassis to stop the coil from arcing to the chassis.

Front indicator is the same as rear 1156.
The clear corner light should be 35W but you can use a 1156 instead.
From what I can find the front park light bulb number is 207. Its a 5W bulb.

Ah you don't want a top mount turbo so for fwd use.
You can get the Kelway in a bottom mount also or most of the other common manifolds available are bottom mount.

The obvious flaw in the HKS design was that they mounted the turbo close to the firewall to clear the P/S pump but then required a crap downpipe.
