My Ride: 2000 328i turbo
Ebay 328i turbo

First off I would like to add that I have very little experience with FI and despite a lot of people telling me not to do an ebay turbo I did anyway.

I have a 2000 328i that I bought it off craigslist with a torn subframe and slapped a ebay turbo on it. Total cost car and all was less than 3k.

Just figured I'd share a few photos with everyone. Its currently untuned so any suggestions there would be great (im a college student so cheap and diy are preferable). Thanks

by the way it is bottom mount. Recently gave it some spray paint as well because why not haha.

Heeheh, engine bay pics or it didn't happen. Not that I don't trust you. I hope you broke that turbo in, they usually don't come broken-in if it's an eBay turbo. I see your car has the ghetto garage stage 2 decals, but if you need a tune, the ghetto garage stage 3 boost tune will do. 14.7 afr throughout your boost range! Leaner is better right??!?

But in all seriousness, you need to get a tune for that or else, the boost gods will destroy your engine.

My Ride: 2000 328i turbo
Oddly enough the only good pic of the engine bay is the one with the turbo and the manifold on. I'll throw up a good engine bay pic when I get a chance.

ghetto garage is basically the theme here haha. the oil lines are just cobbled together with hydrolic line and some hardware store brass fittings haha.

I'm working on trying to find a ghetto garage way to tune it. I understand the afr thing and have an afr gauge (not hooked up yet tho). From what I understand I should be able to log the data with a computer from my afr gauge and ecu output. The whole software thing and reading/writing to the ecu is what I need to figure out.

Other picture is when I took the intake off to tighten up the oil feed line which you can see just chillin out front.

It's not just the tuning, you will need a bigger maf, or a resistor if you can figure out the transfer function for it. You will need bigger injectors too.

did you have the torn subframe fixed? I'll take a wild shot in the dark and say no.

it seems like you've put the wagon before the horse here. one would think that before buying all the hardware, that you would've already done research and known your options for tuning beforehand so that you aren't stuck in a situation like you are now where you have a turbo'd, really heavy paper weight. this is a classic case of uneducated, hasty, "let's put it together and THEN figure out how to make it work", bologna that fills up this forum with new threads each week of someone looking to turbo their e46 for cheap and that ultimately go nowhere because the owner didn't realize the challenge he was taking on, was in over his head, and in the end, just decides to get a different car or do a motor swap.

in the picture you posted, it looks like you're using the stock motor mount. do you have a plan to change that out or is the intake of your turbo just going to be open against the mount arm?

I feel like there have been many honda/dsm cars in your history....

daemoncius--I actually did fix the subframe! Welded these nice size plates in there.

hobbit-- Thanks for the info. I kinda figured that but its good to know for sure now.

carbon-- yeah trashy was the goal lol. The paint is in terrible condition anyway and it has quite a bit of rust around the body.

Lemons status lol. A car like this would be fun to learn the ropes on, then make a nice one.

less than 3k for a turbo 328i, ghetto as fvck but if I had 3 extra grand and really wanted to learn about cars, I would do it.

I rebuilt a 1952 jeep M38A1 to learn about auto mechanics. Then had a volvo wagon to learn more on.

I hope you have another vehicle?? Id recommend getting a tune asap. Doubt you would be able to tune it yourself at this point, but that could save some money. Just get a "Canned" tune and itll be good enough.

My Ride: 2000 328i turbo
Thanks guys. Yeah, I got an infiniti g35 coupe as my daily.

Spent the last few days stripping out the interior of the 328i. Can't wait to get a tune. Anyone know anyone who can tune the ms42? Not lookin for huge power, just a general tune so it doesn't blow up.

The plan is to slowly fix the body and then repaint it so hence the ghetto stripes and stuff. Little by little lol.
