2002 Impreza 2.5 TS

2002 Subaru Impreza 2.5 TS

2.5l 5sp Manual Transmission

Bought her as a mechanics special out of a Subaru dealership in Utah. Drove her back to Idaho, some coolant smell and had an oil drip halfway home. Couldn't find the oil leak or any coolant leak. Continued on and managed 25mpg.

It has been serviced around 110,132 miles and new tires around 99k

What we know so far after doing a full inspection. The oil leaking seemed to be from the grease flung out from the ripped CV boot.

This is the list of things to be fixed:

1. Spark plugs and wires

2. Driver front CV shot

3. Driver side steering bellow

4. Ball joints

5. Outer tie-rod ends

6. Leaking valve cover gaskets

7. PCV in bad shape

8. Air filter needs to be replaced.

Will be changing the rear diff, transmission and engine oil and filter over to AMSOIL before I race her.

Will also need to fix all the other stuff listed. Have some long-term items as well. Shocks/strut kits. Pull out the interior and clean it.

I have wanted to upgrade the rear drum brakes to disk since I purchased the Impreza. I finally decided to do this and over the off season seemed perfect as I had ordered most of the bushings for the rear and would be pulling the knuckle off. I had new bearings and hubs that will work with the upgrade, I just needed to order the hardware and new pads as well as parking brake shoes.

Replacement brake rotors

For the drum brake to disk brake upgrade I researched what rear knuckles where compatible with the 2002 Impreza TS

Replacement knuckle assembly and brake caliper with bracket

A 2004 2.5 TS was the match at the Boise Jalopy Jungle and the rear was complete (minus the struts)

Caliper and bracket

They needed to be cleaned up, so I degreased a couple of times.

I sanded them down, put on some anti-rust paint and then some black paint. I think they turned out pretty good.

Warped all the straight pipe with DEI Gold heat tape.

Overall it was 30 feet of 1.5" tape.

Also did the air box as it sits just above the back of the engine and bellhousing. Plenty of heat generated here with the exhaust crossover down under the engine and transmission in this areas as well.

The finished product. Hope to keep the air from heating up as much heat as I can.
