Any turbo E36's?
-
How is megasquirt? I've seen a few build threads with it. I've never used it before, and I know nothing about it
-
I am tempted to get squirty when i put my e36 back together, I have built the engine and done all the mechanicals/reinforcements etc, and will probably do a low boost setup at some point so I might do megasquirt over the winter and make the turbo install quicker in a couple years. (My wife will love this plan
) -
Its a bit like bodywork, if you take the time to learn how to do it and get things setup properly you will have incredible results. It is not hard at all. You are welcome to come check mine out and see how it works any time
I think the exhaust cutout is a great idea. I wanted to do one on mine if it was too sterile sounding but luckily its a nice balance

)I was glad that i ran megasquirt NA and learned to tune it before throwing a snail at it.

I have no experience with adjusting tunes. I have an open port 2.0 on my subaru, so I am used to looking at tune tables, data logging, and learning views on there. I've just never had experience making my own adjustments. That would be my only hesitation.
What does megasquirt 3 cost?
-
Check out diyautotune.com. I believe the prebuilt ms3 is about $575

I'll have to really read up on megasquirt. I'm not really looking forward to a rats nest worth of wires, but if it's a mich better system I would go with that.
Btw, yes my motor does have vanos.

Do you guys think I should track down a set of s50/S52 cams for it as well right away? I was thinking the turbo would be plenty of power up front, so I shouldn't need to worry about them. Plus that would save me another $400 I could put towards my turbo budget. I figured once I had to rebuild or install a new head gasket, I would install new cams at that point.

I put a turbo kit on my e36 this winter. Using an obx top mount manifold, Tial 44mm, and an hx40. With the obx manifold, and a t4 exhaust housing, You will be able to clear the stock hood.
Just use megasquirt from the start. If I were you, That would be the first thing I would do. Learn how to tune( ITS EXTREMELY EASY WITH MEGASQUIRT) and then tackle the turbo hardware install. Thats the easy part. Anyone can install a turbo kit... its very easy.
I would suggest an intercooler with around a 3" thick core and 18" wide core.
By the way I have that OBX manifold if you would like to buy it. Also have a cast bottom mount in a t3 footprint.
I have an h1c(hx35 compressor wheel with an 18cm t3 divided) if you want it as well?
You can buy the tial from me as well haha.
I recently bought my first shop(house included) so my personal projects are pushed to the side for a while.

And really don't waste your time with cams. A much better upgrade for the money would be putting that money into your fuel system. If their is anyway to run e85, DO IT. Its like gods fuel with these motors. 10.5:1 and you can run 25lbs of boost(on stock bottom end) no problem with the proper head sealing.
Meth works wonders too. But really your first limitation is detonation with pump gas. which happens pretty quick. I wouldn't boost with pump gas only on that high of compression to be honest.

Well I don't think i could put my intercooler right between the radiator and engine. Too tight of a fit. I haven't really given much thought to a t3 vs t4 manifold. Suggestions?
I think I'll pass on the h1c, I'm thinking it'll spool too slow for what I'm looking for. I just might be interested in the manifold and wastegate, pm me asking prices. One i finish my sti swap on my forester xt, then I'll start getting parts for the 325i.
Once my head gasket goes I was planning a .140 mls to lower the compression ratio a little.
I may look into getting megasquirt first, installing it, and seeing what I can do with my stock motor first. I'll have to do some reading on the install and how to make adjustments
-
Personally I would go t3, but I would also never buy a garret or precision or whatever, but a gt35 and this obx with a .8-1 ar t4 open would be dandy.
T4 holsluts are big.
And yea that's a 4" core and I was doing remote mount radiator... Nothing fit up front.
I was just suggesting a nice size core that fits with e36

Yea I was leaning towards a t3 manifold. Most likely going with an hx35 or an eBay gt35 until I get the extra funds together for the real deal.
I have been reading on E85 on a FI application on our motors and do see positive things. How much mileage decrease do you expect while being tuned on E85? I love my 29mpg hwy. Haha.
I'm thinking a t3 obx top mount manifold, hx35, 6-8psi, with 42lb injectors, to start and get it running good. Aim for 325-350hp. Then when I have to replace the head gasket or rebuild the motor, I'll switch to an E85 setup to run higher boost safer. Also adding an enormous amount of power. If I'm not mistaken, a stock 10.5:1 motor with an hx35, about 15psi boost, 1000cc injectors, walboro 255, and E85 should get me in the 450-500hp range. Am I correct in that estimation?
Also for anyone running E85, what kind of O rings, hoses, and seals do you guys run?

I have a turbo S52 in my e30. It's on jack stands right now so you can see up her skirt.
I can also tell you what needs attention to make it a reliable daily driver since I have broken hopefully all of the weak points of the M5X/S5X platform.
Located in Whitefish Bay.

Yea Drleadfoot, any advice is appreciated. I'm leaning towards the hx35 for a turbo, not set on tuning, but I've started looking into megasquirt 3. Until something breaks, I plan to run low boost. Then I'll rebuild and put some money into making it a reliable street car.
