A few quick questions
 

Hey guys, just a few simple questions for ya.

First off my tach has been acting up, it does what it wants when it wants. I figured id find the tach signal wire connector and clean the contact and see if that fixes it. It took me awhile but I found the connector that I belive should be the right one.

The wire matches the yellow with blue strip description I find while searching, but there is no other connector to be found on the trailing assembly. Since I do sometimes get a tach signal id imagine the PO tapped the ecu wire for the signal? Would any harm be done if i jumpered the leading coil bullet connector to this open plug as a permanet signal?

Second question, Some of you may have seen my thread awhile back about my turbo getting fragged by a chunk of plastic from the spectre intake the PO installed. I got the turbo rebuilt and cleaned and all seemed fine. But to day while I was looking everything over in the bay I noticed my exhaust housing has turned pink?

This picture dosnt do the color justice at all, its extremly pink. Is this just a by-product of it being heated, or am I running lean or something. Replacing the turbo was the most in depth thing ive done on this car in the short time ive owned it and this color change has me worried a coolant of oil passage is blocked to the turbo.

My gut is saying this is ok but after seeing the turbo when I first pulled it off im second guessing my self.
The car is 90 gtu with a t2 swap
non-enclosed cone intake
3"dp and ressonated mid-pipe to 2.5" dual mufflers
boost controller set at 8 spikes at nine
redom ecu
Thanks for the help!

It's just a Hello Kitty Edition turbo.

You said it got rebuilt recently; did they paint the turbine housing? Or maybe they used a cleaner that left a residue, which is now pink.

Im not sure, but it was very black and glossy.

jumper the two bullet connectors together.this should give you back your tach signal.
Do yourself a favor and check the plug wires,and plugs too,as the signal comes when the plug fires.If the plugs are fouled you get intermittent tach.If a wire is bad,the tach doesn't read correctly.

Will do, I just put new ones on before I stored it for winter. Do I just check for continuity with a multimeter?

Well, there you go. EGTs can be around 1800F, so paint on the turbine housing isn't going to last.

That's what my first guess was but, I wanted to be sure.

^ HAHAHA! But it could like everyone else said, they painted it and since that part gets stupid hot, paint isn't gona last at all, probably after the first day it was already starting to "Bleed" into the metal and after continuous heat, it just blended in with the metal and slowly fade in color. I really wouldn't worry about until you start to see cracks, chips, or even find a leak in it. Look it over more for those signs.

I called the place and they said the chemicals will bleed just like you guys said, one lasr question, should I remove the tap into the ecu wire for the tach before I jump the black connectors? And what wire is it on the ecu plug that feeds the tach.

Any one?
