Default I bought a turd!!

Hey all. Been quite a while for me on this forum but I am pleased to announce that I am back in a Subaru and have in my driveway a 1-owner 2002 WRX!

"Yay" except that, at 150,000 miles, this car is overall in pretty rough shape and is considered a project by my definition...dog hair-covered interior, squeaky throwout bearing/ wicked clutch chatter, rust hole in the rear subframe and rear quarters but for 2300 I figured what the hell! I'll put my efforts toward the mechanicals and rust, clean the rest and enjoy the drive.

I do, however, need some education on how to properly utilize a couple items that came with the car, an Innovate Motorsports LM-1 wideband O2 datalogger and an APEXi SAFC. Both items are BNIB but I am not sure how to use these devices in conjunction to exploit their offerings. If these things are useless, then great! I'd like to know this so I can stop trying to figure this stuff out.

Since I myself am a search-nazi, I did not find answers to my questions so any help on these two items or weak points of the car (head gaskets?) or areas to address besides what was mentioned above would be great.

I'd post a pic of the car but it's pretty embarassing.

Can anyone help a brother out on the wideband and SAFC?

You can sell or toss the SAFC, and the wideband unit you have is more for a tuner than a permanent install in a car. The LM1 is designed to be portable, it was replaced a few years ago by the LM2, but it's the same basic idea. If you want to get a good wideband O2 for the car you can pick up an Innovate MTX-L or AEM UEGO, both are affordable, reliable, and perform well.

Things you should address on an old EJ205: valve cover gaskets, vacuum lines and anything else made out of rubber that is replaceable, spark plugs, remove the catted uppipe, install a fuel pump, optional downpipe, tune. We have had a string of 02-05 WRXs lately with high mileage and a little bit of neglect, but most of them clean up and run nicely with some basic stuff. 12+ years on the road in New England is a LONG time for any car.

If you are not mechanically inclined I would strongly suggest taking it to your local Subaru performance shop, where at the very least you can get a list of stuff to tackle.

Tom from Wicked took my 02 wrx with 175k on it for a ride and pointed out some things to be concerned with and didn't even make fun of it! Don't be embarrassed dude. Only be embarrassed if you aren't trying to make a gem out of the diamond in the rough! All my issues wound up being a bad fuel pump just saying

Do yourself a favor and sell the SAFC
The LM1 for a car that isn't highly modified doesn't really tell much that is useful.

I like this topic, is relevant to my interests. Are you saying proactively replacing the 12+ year old fuel pump is a good idea? Mine still works without issues, hadn't given it much thought.

Thank you for taking the time to post.
I will be performing all of the work on this with the exception of tuning for any upgrades that may come along, which is why I was asking about the actual "value" of the two tuning items.
Ultimately the car will be gutted once the GF's car is out of the shop (couple weeks from now). Since you're only 30minutes from me, I may just stop through to check things out.

Not making it a gem but definitely not going to let it slip away into total disrepair. Looking forward to the project, no doubt.

Understatement in bold. You weren't kidding!

Everything is so......fragile under that hood. I have vac lines that shattered when I was working in the engine bay...can't wait to see what happens when I start taking the car apart.

The flex section of the stock plastic intake (turbo side, beneath the intake manifold) has been known to crack as well. Check for leaks and upgrade that crappy OEM pipe if not already changed out.

Any thoughts on why I cannot get above 10psi of boost? My gauge is saying boost tops out at 8.5.
Does that suggest an (intake) boost leak as mentioned in the previous post? The car feels okay under power, albeit with some surging, but I thought stock boost was closer to 15...?

If it makes you feel better, I bought a 2002 wrx that didn't seem like a turd at all. I now have about 6,000 dollars in just repairs. At least you know yours is a turd and got it cheap!

Also, don't let this scare you. The guy who had it before me used the wrong viscosity oil and I didn't find out until I lost a rod bearing. I changed out the short block (with a 2.2) instead of changing the whole motor. That way the guy doing the work could get down inside and see if anything else needed replacing, and replacements did happen.

I use the same oil in everything. One 5gal bucket is much easier to have with 7 engines that require oil changes (cars, mowers, generators, etc)....saves on the oil debates too!


As far as this boost leak...the car came with an AEM CAI (the filter resides behind the fog light) however the leak existed prior to any work I have performed. I did have the TMIC out last week and resecured the y-pipe and clamps but did not check the plastic...err...manifold(?) (the item that skimobile mentioned) that goes from the intake tube to the turbo inlet.

What are the chances of a leak in one of the seams of the TMIC or better yet, how would I go about pinpointing the issue?

Do you have boost right away or does it take a while to build? The lack of boost could also be a stuck actuator on the waste gate. I had mine stick on me I took a pair of channel locks and worked it back and forth a bit and fixed the problem.

There is certainly no delay whenever I step on the gas. The gauge responds and the turbo sounds like it's spooling right up but the sound is loud-ish for a stock turbo, IMO.

8.5 lbs is basically "limp mode"..... you might want to pressurize the system and do a pressure/leak check of the intake system.

If the car had been modified at one time and put back to stock you may be missing the restrictor pill going to the wastegate. http://www.perth-wrx.com/vb/mechanic...-you-need.html

Clearly Ive got a very basic understanding of how a turbo system works but those links, once I can sit down to read them, will prove to be very educational. Thank you for taking the time to put them up. Also thank you to the other folks for putting up your thoughts.

Anyone know for certain if the spare tire area between the sedan and wagon are the same? I've sourced some wagon sheet metal to repair my trunk seam provided the stampings are the same
