Buying a ST e92, what would you look for?

[J. Dub]

I'm buying an e92 ST. Below are some of the mods the owner has done as well as questions I have for you guys as my only experience is w/ my old FBO e92, so this will be a big upgrade in power for me & I'm new to the ST world.

My Questions:
-What are some things I should test for when going to give the vehicle a once over?
-As this is a stock rear axle w/ 99k miles I understand it would be best to upgrade the rear axle. I'm assuming 8.8 rears are the only ones not breaking w/ hard launches?
-Are you guys still using black labs to send oil analysis to to check bearing wear? (It's been 2years and some change since I've been in the n54 world)
-What would you do when buying a ST n54 before handing over the check?

Mods/Details:
has 99,xxx miles
Automatic with xHP stage 3
Doc Race kit with JB 6266
Tial wastegates with open dumptubes

That's what I was missing... Leak down test. Thank you. For oil analysis do you guys still use blackstone labs?

You and me both. I am assuming it's custom.

Good to hear I'm not out of touch as bad as I thought on the N54 platform. Cheers

I would run it hard to make sure it does not throw and CELs. Also, to make sure the tranny does not act up at all. More than just 1 through 4th at WOT. Really get it hot. I don't trust automatics.

With just the single lpfp upgrade what ethanol content can it run?

Did they ever dyno it?

With stock motor mounts I would be worried about the pulley. An easy fix.


You do not mention any suspension work other than all new bushings front and rear. I really doubt EVERY bushing was replaced, I would ask for the receipt to see what was really done. Assuming the suspension is stock at 100k miles and probably around 10 years old it will need attention at some point.

What wheels and tires?

Pics of the car?

What is the asking price if you do not mind sharing? I see builds that are well worth the asking price and others that are crack head prices. Which is why I ask.

Here it is, with pics https://www.e90post.com/forums/showthread.php?t=1667166

You bring up some good points. Ohlins coilovers and other stuff I didn't put in the OP as I was more concerned about motor. But that thread has all the stuff you were asking about except dyno

That is a nicely put together e92 from the pictures. Gotta love the white with the bumper and the lip etc. Very clean on the outside. Quality parts. Looks great.
