Cool zboot's 328ti Project - A couple years early

So,

I've bought a m52 2.8L from a 97 328is along with it's ECU and EWS module. Unfortunately, the keys to this vehicle are likely lost so I'll have to be towed to a dealer for realignment later (AAA Plus FTW).

This all started with my engine going kaput on a trip to upstate NY to buy parts from Rendoll so I could finally fix up my rear end. I still made it up there and got those parts.

Anyway, a swap was in the future of my car, just did not expect it to be so early.

So, I realized today that there is a major component I did not have - namely a 6cyl exhaust. This is a problem because I'm pretty much broke for the next 3 weeks . . . there are options. . .but I don't like them and neither would you.

I'm likely going to be bugging some of you guys with questions about stuff, so why don't I start now.

I've found a complete 96' 328is exhaust system for $250 + shipping. We've not firmed up the deal, so there is slight wiggle room in negotiation on price or extras.

Anyway, aside from the exhaust pieces themselves (cat + muffler), what else do I need from that car exhaust-wise? o2 sensors? connectors?

Also, from talking to the guy w/ the exhaust, I'm going to have to shorten it. About how much should I expect to pay for someone to weld together the pieces I cut? (I may just end up doing this myself. . .)

Now, I've got all the engine accessories + wiring harness and plan on using the 318ti radiator. Are there any other miscellaneous engine stuff that I may need or is the engine part just a bolt up and wire down?

This weekend will mainly be taking apart the front end of the car, removing the tranny, disconnecting engine stuff, fixing my window regulator, fixing the cheapo m3 replica bumper cover, and attempting to fix up the nose panel. Pictures should be up of the initial stuff Sunday

well what about a junk yard they may want a lot less for a 6 cyl exhaust from a bmw than the 250 plus shipping of a long exhaust.

Regular e36 mufflers are HUGE and dustin and I had troubles trying to get his on his car due to size. Just Y pipe the exhaust into a 2.5" exhaust after the cats and into an autozone muffler. Yes you need the o2 sensors, all 4 of them.

Get rid of the bracket that holds the m44 powersteering resevoir to the chassis. CUT IT OFF THE CAR!

i don't think id re-use the Ti radiator for starters...

like blue said, get rid of the PS bracket and coilpack brackets before you put the new motor in... they won't get in the way of the motor, but make it a PITA when working around anything in that area.

Im assuming the motor still has the headers attached, so those 2 o2 sensors will likely be intact and still there... you will need the post-cat o2 sensors, i found some good used ones on ebay for $50 shipped, and the motor should already have the connector for the engine side as part of wiring.

if you didn't read the reply in my swap thread for your question, i say go have a gander at it.

IMO, if your going to do it, do it right and go all the way. I wouldn't be taking shortcuts like running like 4cyl radiator and such.

anyways though, congrats on the swap! its going to be fun i promise! - you'll probably have yours running before me ... lol

I've got a dinan exhaust already on my ti - can i use that or will it be taking up too much space as well?

About the PS resevoir, does the m52 has its own on the engine or would I be relocating the 318ti one elsewhere?

I don't really have too much of a choice right now. In a couple months, I'd have enough cash that I could switch to a 6cyl if the 318ti one doesn't seem to be cutting it.

Yea, dustin and i both used the m44 radiator. I now have the 6cyl radiator installed.

If you have a Dinan catback, you can have your midpipes fabbed up to that if you wanted.

The ps bracket is where the 6cyl alternator will sit so it has to go no mater what. The 6cyl ps resevoir should sit right behind the alternator or something like that. I dont have PS so someone else needs to help you there.

Still need some advice on the PS thing though I suppose worst case, I'll start to learn about all the stuff I'm missing or need when I'm putting the motor in.

I'm feeling much better because while looking over a calendar and my monthly budget, I realized that I forgot to include a second paycheck for this month! So, I'm not quite as broke as I thought (or at least in a week, I won't be).

So, perhaps I can still be on track to finish by July.

the PS res mounts on the drivers side motor mount bracket, behind the alternator.

What motor is Dustin running the M44 radiator with? I thought he had a DASC on his Ti and then bought the M3???

As far as the exhaust, you can just do a custom Y-pipe to your stocker like blue said. Thats what I did with my stromung, but I had to chop into the pretty stainless pipe by about 6-7 inches to make it work with the 6cyl centersection

Question: Are M3 front brakes ok if I stick to the stock rears? Also, would I need to upgrade brake lines?

im sure you know, but M3 brakes MUST have 17" wheels... no question about it. Personally Id just go with 32x vented fronts, there is less to worry about as far as cost and whatnot... and we weigh less than a normal E36, so I think it would be fine to use normal vented fronts.... just get nice pads.

Stock in the rear should be okay, since 32x definitly use same stock rears...

Brake lines are the same as far as Im aware, but if you got the extra money, get a stainless steel set... they are worth there weight in gold.

We're not talking about Dustent, we're talking about my buddy Dustin (bloodrunsdry) and his 325ti.

I have them with the stock rears. The m3 brakes use the same non-m brake lines.

You can use 16"s with your m3 brakes, its been proven.

grr. . .upgrading to m3 brakes means i definitely need to get a new set of rims. i suppose I'll add that to the list.

Thanks blue. One thing I've found is that jobs go a lot better when you're prepped ahead of time. I can imagine putting m3 brakes on there and then trying to get my 15s back on only to whack myself in the head for not thinking it through

Oh, and some good news - the shop I bought the motor from found the key! Yay. Saves me some stress with towing to a dealer near Erie PA and hoping the car would start after the realignment. (Paying for tows is not part of the swap budget).

16s will work some without modification and some you will need to grind down the caliper.

but 15's doubtful
hey tony are you running just m3 calipers and rotors? or did you go with the brake booster as well?
