I have some family in Austin and the rest over near Bass Drop.
D-d-d-d-d-d-drop the bass! Does Skrillex live there?

skrillex sucks. badly. Deadmau5, Knife Party or Daft Punk would be my first choice.
The whole town just bumps hard. Every single person in that town has a tahoe with 4 18s in back on like 10k all day.

Anyone want to convince me on which setup I should go with? Turbo m20, or turbo m5x in the e30. I want around 350whp on pump gas, and something I can drive every day. Also want to keep the build from unecessary expenses.
I already have a clutch, and a turbo, and surge tank. Main expensive things are 1)picking a motor and 2)turbo manifold. Which is probably the biggest issue for me so far. I'm not sure If I want to spend the time to build a full twin scroll manifold for a 24v e30, just for 400whp. An m20 turbo manifold twin scroll adapter seems very appealing and very quick.Here is some of my concerns from BF.C thread.

^^^Yup,the question is what do you do with that 500whp in the E30
I have 255 R-comps,proper suspension,E36 M3 brakes and whatnot.With 400/400 it is handfull to drive,but if I remove the wing it is downright dangerous with 300/300.No rear grip whatsoever.What is funny,I brought my wife's new to her '09 Z4 to the track.With 225F/245R Bridgestone runflats and adaptive supension this car has more grip than my [not] fully sorted E30 with R-comps
Ok,almost.Thats exactly why I can't justify m5x in my attempt at daily driving a turbo e30. I just want something to have fun with, and that is somewhat reliable, at around 350whp which is perfectly reasonable for an m20 on pump gas. I feel like if I put an m52 in there, I would end up making 500+ and ruin the whole daily driven aspect.
But the other idea is pump gas + stock compression unopened m52 with studs, and try to make 350-400whp with meth injection? the appealing part is that I have an entire m50 swap sitting in the garage with mounts and all, but a headgasket job on a m50 will basically put me out a couple weeks of driving haha. With an m20, I can have a new head on within a couple hours. And the m50 turbo manifold is a PITA compared to the real simple manifold adapter.
MAN I'm bad at this.

It seems like your argument against the m50 is a bit ridiculous. From what I can gather it seems as though you are afraid of "accidentally" making 500whp on a turbo m50. The m50 will be easier to make power with at lower boost levels for a simple reason... it's a more efficient head design with 24v. The m20 will be cheaper to build and fix but an m50 isn't that much more. All you need to do is hear John's (drleadfoot) e30 with the turbo s50 run and you'll be a believer.
Now i'm sure Snap's m20 sense is tingling and he'll be joining soon.

m50's really aren't that complicated or expensive. They put an m5x in damn near everything from 1990 to 2001 so finding parts is simple.

Now you gotta explain yourself lol. Ill be building the turbo manifold(m20 is by far easier, just a simple adapter) and Ill be doing standalone ms2. And with the 24v ill have to do something about the compression ratio for pump gas. I don't want to redue all the timing and stuff, so head studs plus meth injection will be it for the first round.

I have seen plenty of turbo m50 cars running pump gas with nothing special done for compression.
Ask Snap how much fun it was to put together his turbo setup and then ask people who have turboed M5x/S5x motors.
If you think of it, the m50 breathes better and makes more power out of the box. That means you would need to run less boost to reach your power goals with an m50 versus an m20. If you chose to do a vanos motor that helps you even more=)

Boosting stock compression on the m50 isn't an issue either. If someones looking to run in the 400+ range then they are lowering compression to a more suitable 8.5 or 9 but for an m50 running 10:1 on 8psi is not a problem to easily make 350whp.
Why do you keep talking about adding meth?

Okay so I have a holset turbo with t3 exhaust side split pulse that I will be using. I will need to run 15psi+ as it wont be efficient below that. I will definitely have a twin scroll manifold.
I am talking about adding meth because I'm not going to use a headgasket spacer, and I'm not going to use forged pistons. This will take care of the compression ratio issue. This will only be a 300$ endeavor though, so its not terrible.
Okay so I think I might just do 24v, simply because I have the entire swap sitting in my garage..... and I'm getting sick of trying to find an m20 motor for a reasonable cost for reasonable miles.
So I guess that means its time to get used to the timing and O ring the block/change the head gasket?
I'm guessing the head gasket/timing stuff will cost me close to 300$ for the materials? I already have the bolts I'm going to use, and I will O ring the block with SS welding wire I have.
Anyone think I should mill down the stock pistons to lower compression at all?

Paging Snap. When are you going to CAD model and recreate the Racing Dyamics 24v M20 head?
I know you've thought about it.
