E36 Hater's Phase 3, AKA what's a budget build?

[NOTORIOUS VR]

Try it out with you own car and you will see what happen in a year ,bullshit that you have seen it many times because it will crack eventualy, search on Swedish/Norway forums and you will see the pics with cracks .

Yawn.....

T3 .70ar bep housing, sane as before.

I'd look into a bigger housing. TurboLab is now selling a .82 T3 machined for hx40.

I floated exhaust valves (and bent a couple) on mine at 37psi and 9300 rpm. Presumably from exhaust back pressure. Had kiggly beehive springs with titanium retainers set up at 97lb seat pressure.

I'm sure you won't be running that much boost but it does point to a choke issue. With less boost and your nice wastegate placement, maybe it will work around the issue a bit.

I ended up selling mine and bought a Forced Performance Super99. That should take care of it

Don't tempt him, he'll do it lol.

So far so good with mine.
My worry is less with the weld, but more with the rigid design.
Especially since I'm returning into the DP. I think if it was setup for open dump, I would have less worry of cracking. There is a lot of force going on there when all assembled, then you have expansion due to heat, and movement of pipes.
I added a flex immediately after the WG, just before it ties into the DP.
I wouldn't bet $ it won't crack, but I'll hope it doesn't .

I didn't know you did that. Is it in your thread? I'd like pictures of it mounted.

Measuring EMBP might be a good idea at the least

I'll look into a bigger turbine housing, I had her over 30psi last season for a while even though the woodruff key was busted.









Downpipe and exhaust are still in progress but all the reinforcements and driveline upgrades/bushings are in

Just need to finish grinding down the calipers to fit the drag radials.

Are those the Megan Racing arms? I miss mine. I should have taken them off my wrecked M3.

Good eye they indeed are Megan Racing.

[tptrsn]

That's looking sweet!

What's up with the CV joint at the rear of the driveshaft, is that an M3 thing?

DSS switched to this design with their v2 of the one piece moly ds to eliminate vibration issues

And from the sounds of others reviews, it wasn't fully successful

I've heard of ppl still having issues but I've never had any in the 3 years i ran one. I guess i was one of the lucky ones!

Muy muy nice !! Where did you get the reinforcements done?

I thought the CV Joint was standard for all 6 bolt driveshafts.
My 09/96 M3/4/5 has a 6 bolt driveshaft (OEM) and uses a CV Joint at the rear.
My brothers 09/97 M3/4/5 has a 4 bolt driveshaft with a u joint in the middle and at the rear.
DSS offers there drivehafts for both the 4 and 6 bolt diffs, you sure the cv joint on the driveshaft isn't just specific to the 6 bolt design like oem?

Everything is getting done over at silokin automotive in bayshore, hes a good friend and a great fabricator.

DSS uses CV joint on rear and U Joint on front. I have had new DSS 4 bolt and 6 bolt shafts in my car during the past 3 years. DSS may have done things differently 5-10 years ago.

So the turbine outlet is 3inch vband, my fabricator had went to 3.5 at the flange, and before the downpipe gets to the transmission he flared it to 4inch.

The new exhaust is massive, but I love it.

[tptrsn]

I hope you're able to shoot and post some more pics of that downpipe, it is pretty sweet.

[Damokun]

So I noticed that your turbine side does not have the external wastegate, and I'm assuming that that's the turbo lab upgrade that's responsible for that. In order to go with an external on my future setup, I'd either have to upgrade the housing or weld the flapper shut. Do you know if that affects flow characteristics at all vs the new housing. And if I weld the flapper in the interim, should I get the adapter plate?

Just get a new housing. The internal wastegate creates a huge amount of turbulence.

Your rear subframe bushings look like they are either missing the large thick washers on the bottom or you have thin washers that have cupped a lot. Either way you should sort that out to stop the rear subframe from moving around.

Where? The large washer is on there

These are the bushings

The picture of the forward end of the diff you can see the forward subframe mounts. If you look at the large washers you will see that they are quite cupped. This has been a common issue with some of the subframe mounts that are out there. Some people order large thick washers from McMaster-Carr to fix the issue. I made shims and used large thick aluminum washers on mine to make sure the inner bushing was pinched and the poly bushings were firmly retained.

But the bushing itself is cupped?

[5mall5nail5]

My car and couple other cars seem to be doing just fine with stainless welded to stock cast manifold. Try it yourself because you will see it actually works.

Google LS truck manifold turbo kits and you will see about 10,000 people doing it with success.

There's a lot more surface area to a v-banded truck manifold than there is a 30 - 40mm pipe to an exhaust housing.

I am very familiar with the pre heat and sand cool down of cast welded stuff and, in my experience and from seeing other peoples projects, it will crack eventually. There are rods (Ni-Rod) meant for this application, but it's never recommended on stuff that has constant heat/cool and vibration. Feel free to do it, but I didn't bother and went through way more effort making a second wastegate fit on my car. Welding the cast housing would have been way, way easier, but I don't have a good feeling about it.

Additionally, Mike may or may not have been using stainless hotsides - not sure. Either way, Mike is comfortable with it for his application but I wanted to avoid on mine.

[chikinhed]

Oh, I see. Does the large washer follow the contour of the 'cupped' poly bushing?
