I was doing burble tunes before it was cool. My Volvo 240 made much better sounds with DFCO turned off than my E30 ever did though, and I'm not sure why. I could never get the M20 to do more than a couple of pops here and there but the B21FT would crackle and burble like my bike.

The imitation burble tune's coming on M cars are a very real thing. I've driven a M2c and if its between 2500 and 4000 you just tap the throttle (like you where pushing a button, it take no effort) and it makes pops for a few seconds. Its all show and its only there to make low speed downshifts cool. Its so fake, you can predict it every time, the period, loudness, and when it happens. I know the car has piped in audio, you really cant tell which is the fallacy right? Inside the car it sounds very good, and if you didn't know better you wouldn't know.91' 318is 90' 325is

GTI, Mustang, BMW, they all do it in one form or another. Either noise pipe, or digitally.
Whoever thought up that idea to start with should be shot.

There's a Renault (IIRC) that allows you to change the speaker noise to a Megane, Clio V6, and an F1 car. That's kinda cool.

The new "cool" feature BMW has put is like a Jedi control move on the car. It basically reads your hand motion and can do certain tasks... like turning the volume up/down ... because turning a knob was just too much f'n workSimon

Yeah it seems like all the new turbo cars (including BMWs) have burble tunes on them either stock or aftermarket. It's even a thing on the older cars (MKIV VW, E36, Z33, etc.) Not sure which came first but I look forward to it going away. Pops and flames are an earned byproduct of power. Under 3k, rpm they sound stupid.

Yeah, seems to be the case as of recent. E30 value appreciation has something to do with it probably. But ripping the M20 out of a perfectly clean car was never a good idea. So glad I recently finished my 24V swap... but it was an M10 auto so at least that.
Originally posted by ForcedFirebird View PostI've gained a lot more experience since, specially in the last 3yr or so. For comparison, in 2015 it took me larger valves, porting, headers, stand alone and ITB's to break 180whp, I now do that just mixing/matching/balancing stock parts, no porting or headers and using the stock ECU etc.Digger knows his stuff. He has sent a few stateside clients over my way when they are looking for m20 cylinder heads.
Would you care to elaborate on the things you've learned about building engines? There's some info that can only be learned from experience and I would assume that this is it.

Suspension work takes anger, a big fucking hammer, and a torch.

In other news, I said I would drive the Ninja 250R for another year, but went out and bought a thrashed CBR600F4 last night for $1000. It runs/stops nice, but the fairings are bad, it pops out of second gear, dash/headlight wiring is destroyed, and just generally needs a lot of love.Originally posted by priapismMy girl don't know shit, but she bakes a mean cupcake.Originally posted by shamesonUsually it's best not to know how much money you have into your e30

The biggest thing was moving the head machining in house. We had a race car in Finland about 4 years ago who flow tested the head after he got it, and it didn't match the numbers here. Couldn't figure it out at first, then realized it was the valve jobs being done at the local machine shop. We did all the flow research and bought the seat cutters to suit. Never thought anything of it since the cutters for the local's Serdi machine cut all the angles in one short. So, we did a little experiment and ported a head, flow tested it before and after bringing it to the machinist - it had lost significant flow. Now I use a machine that cuts each angle, one at a time which is a bit more labor intensive than a single pass on a Serdi, but as the old saying goes "The machine is only as good as the operator." Another big one was getting the perfect squish on the angular part of the m20 pistons/885 heads. Milling the head, torquing it down, measuring squish, then pulling it back off to get the perfect number. The m20 really likes .037-.039" of space between the head and piston. Then little details like weight matching all the components to within tenths of grams, double/triple checking clearances, polishing bearing surfaces etc. I guess in a nutshell, QC has been the biggest factor - stopped subletting out as much work as possible. There's a huge difference between caring and someone who operates a machine for a paycheck.
