Nice progress. Wish I had time to boost my e30

So its the coldest day of the year so far here in Minnesota.. It was -14f before windchill this morning! For some reason I decided to work on the car today still. Our heater did great at keeping up with the cold!

Finished oil lines today for the most part.


Had to drill out this adapter and find some bolts that would fit.







Oil Feed spot + adapter for an oil pressure gauge



Yup that'l work I'm thinkin



Had to take apart the turbo housings and swivel the whole thing in order to fit that drain line in.... its a really tight fit coming off the turbo. I'll post a pic when its together so you can see the clearance... or lack there of..... Either way, found a spot that I think will work and decided to clean up and paint the turbo outlet housing while I had it all apart.





My brother doin some painting. He's also painting the valve cover in the background!

Thank you so much for the reply! Really good information. I'll have to fly somewhere to buy mine. Hopefully CA to avoid the rust buckets in my surrounding states. I'll keep you posted! Thanks again!

I really like these gauges. You probably will too.

I'm curious if you want to give me some insight on the e91? I'm really wanting to purchase one. I'd be changing from a B6 A4 3.0 V6 to the e91. I've been holding off for a manual. What are some pros and cons you see with it being your daily driver? How is the storage on them? Feels like it might be slightly small.

#1 I like podi gauges too but don't wanna spend that much at the moment. I'd love to upgrade to one of those podi vent gauges at some point in the future.

#2 I'm sorry to hear that your suffering in that 3.0 A4. I'd say the e91 is about the same size as a B6 A4 wagon. Its not huge but I constantly use it for hiking and trips and can stuff an amazing amount of gear in the back as well as my dog sometimes. I was also looking for a 6 speed version. I ended up flying about 4 states away to get mine and driving it home. Try surfing e90post forums, they have a bunch of e91 guys that are constantly surfing and posting available e91's...

Otherwise its an extremely reliable and tough car, mines almost at 170k and it drives and feels like a brand new car still. The real key is finding one thats been maintained well... As with any BMW, the oil pan gasket will eventually leak, oil filter housing gasket and valve cover gaskets are common. The intake and exhaust cam solenoids are common (take them out and clean them occasionally when your doing an oil change, this prevents the issue and they are right up front and easy to get to)... I've thoroughly enjoyed mine, its an absolute joy to drive. One of its main downsides I see with it as my daily is its sometimes a bit too smart for its own good. Just stupid things like electronic oil dipstick, ect. If you do get one tho, look for one with the sports seats, possibly the best seats I've ever sat in! All in all, It's not the quickest thing around, but extremely fun to drive still, and she's an absolute looker.

Found a 16" SPAL on craigslist for $60 today!! That'l do!

i will stay tuned to see the results with your "Ghetto way" of installing the ARPs as my engine had them installed the same way and i plan to boost it soonish. hopefully yours holds up great and gives me some confidence in the stock gasket at reasonable power levels!

This is definitely ghetto.

As far as OEM BMW head gaskets... they're the best. There's a reason why the BMW ones are more expensive than others.

[SirMaxximus]

Jeez, 5.6 fru that's some gravy man! BMW pays us 3.2 to replace the valve cover/ gasket on a N52 e9x, and that includes installing the part and the test drive afterwords to make sure you did the job right. Nice job on the build so far.

yea Mate it wasn't too hard, definitely annoying and more time consuming than I expected tho. I was surprised at that number as well...

So little story on this brand - Lots of good reviews and such, I had 3 friends using them successfully on their builds so I bought a 44mm one for my M20.
I blew the diaphragm on it not once, but twice when I ordered another one thinking it was a fluke. So now they're cool <$100 desk paper weights. I bought a TiAL after that's served me well for years and is doing great even today.
My point is be careful and try to do things right the first time. Make absolutely sure you enable the boost cut off parameter on Megasquirt so you don't feed your engine 50psi if the diaphragm decides to let go on yours too.

Also, not sure if you want to go through wrapping the manifold again, but you're encouraged to dump the wrap into water before applying for a nice tight fit.

Yea I had read some good experiences as well but was pretty unsure still with an ebay wastegate... If I have any issues with it whatsoever I wont cheap out next time for sure, at that price point I figured it was worth the try.

I've seen people have pretty good success with it at sub 10psi boost levels. We will see for sure!

Meanwhile. this week my daily broke... not what I wanted to be spending money on. but spent a hunk of the weekend fixing my e91 wagon. If anyone has to fix the crankcase vent on these, its integrated into the valve cover and pays 5.6 hours on alldata.... also it kinda sucks

your thread got me curious as to the VDO boost gauge, and it looks like VDO does make a nice OEM+ looking analog boost gauge called the "cockpit" series. that's what style my gauges are and i love them.

Yay another boost build.

Pic of random parts piled up. not all my parts going in. but a hunk of them



Installed the ARP head studs yesterday! Did it the ghetto way (one at a time) without removing the head, chain or gasket. hopefully keep my head in one place under some boost!

[SirMaxximus]

that's a cool setup for a turbo feed. i'll have to bookmark those for future use haha. i am using an adapter block that attaches where the oil pressure sensor is so i was curious if you were doing the same. you could definitely use one for your gauges if you don't have a plan for those senders yet.

Yea I have a little adapter already worked out for that.. basically a really small oil distribution block. but it has all the spots I'll need covered. I'm sure you could use that same AN-4 line and attach it to your adapter block.. It fits nice on the M50 and has just enough slack so I'm sure you could reach if needed.

[mitchlikesbikes]

Awesome I'll check out summit for pricing.. I like the VDO vision series but after a sender and whatnot it ends up being like $90 for a really basic oil pressure gauge... I'm probably just getting to the frugal part of my purchasing now that I'm starting to run out of parts to buy! Maybe I'lll look into the summit brand fan's then! I love the idea of a SPAL knock off! haha

heres a link to the oil feed line I bought. Its already made to the right size for 24v motor top mount style. feeding it off the back of the oil housing.

also if you have a vanos motor. heres a link to an adapter that will keep your vanos oil feed line in place and add another fitting for your feed line

https://rallyroad.net/collections/forced-induction/products/vanosbanjooilsupplyfitting

Thats how I'm planning on running it!
