That swap depends on if I want to use it as a DDor weekend driver.

For DD - m50 with extras
For WW - m42 turbo

I love physics.. Taking my last engineering physics class this semester!

[Thizzelle]

And to talk a bit more physics, we're doing Newton's laws (basically second) right now. Which is hard as hell when ALL you have is F=ma and you need to find the applied force necessary to accelerate a bobseld with a 0.10 coefficient of friction to 60km/h over 75m on a 6* incline.

it will become all so clear when you are older and have to repeat it in college
all the way up to Physics 4? I hate school

If I have the patience, I'll just wait until someone can comment on the quality/reliability of that turbo setup. One of the biggest things that I really don't like about the m50 is that you need s50 cams for it to really be worth it, and just those cams and a chip with them is going to be $500+ for not a whole lot of HP gain. But without those cams I might as well just swap in a healthy m20 for like $750 and call it a day...and then again with all that, is the power increase really worth the work and added weight? The answer to that is likely no.

That's a lot of pointless rambling, but it's part of what I need to consider. S5x would obviously be by far the best decision, but then that's about 2.5x the cost of either of these things.

cary, what is the gasket brand? and bolt brand? that could have been a head bolt torquing issue.

Don't bother with turbo, it is not legal.

Swap in an m30

gay!

sysly the m30 is the biggest waste of time and money that could you do to an e30.

S5X or GTFO.

The m30 is a fraction or the cost of an s5x.

We are talking about best budget swap for vivek, not the best swap. Turbo m42 sounds dumb.. m50 with extras just doesn't seem worth it. Do s50, but that is just more expensive.

The m30 can be done for the price of swapping in an m20. It is also a lot faster, and has same old simple technology.

[Vivek]

Fuck that, too heavy (along with like 20 other reasons not to do it). It would be awesome, but in my eyes there's a reason it's not an especially popular swap. Every time I consider an m30, I look through Frank's guide and the desire quickly goes away.

Yes, turbo's are illegal, but I'm just wondering if it may be worth the risk. I'd have to really weigh out the pros and cons of each.

If Danny sees this and wants to chime in a bit about his ref ticket that'd be cool. A turbo will be relatively easy to return back to stock, as long as the whole referee process isn't too terrible.



Edit: but I'd like to know more about swapping an m30 for the price of an m20. I sold an entire 94k m20 driveline with an LSD for 700 bucks.

[golde30]

Don't remember the HG brand, but I think VR. Headbolts were OE new, I never reuse head bolts.

Now, turbo m42 properly done would cost a lot more than an s52 swap. M42 are not exactly bulletproof to begin with, and are also on the high side for compression. So forged pistons, rods, and cosmetic HG for the short block. Then manifold, turbo, piping, fuel system and standalone= $$$$. M20 however is bulletproof, you can boost the shit out if it with just an upgraded HG and bolts. S52 can be had for $1500 nowadays, what's the problem?

[Cabriolet]

the m30 is a joke. it weights a ton, costs a ton to get up to muster, has no real power, is not documented very well, is harder to get parts for and under preforms in mpg, kW/liter and is lower power out put. anyone that has done this swap is retarded. i wouldnt even do it if someone even payed me to do it.

save the money do it right the first time.
hens the reason im going to do the EVO3 conversion on my s14.

[Vivek]

Turbo m20 is also an option, but that involves both an engine swap and a turbo which is basically twice the money, work, complications, problems...m42's have forged rods and (of course this statement is up for discussion) you can lower the compression enough with a thicker HG to run low (sub 10psi) boost without blowing anything up. That'll be a bit over 200whp from what I've gathered.


Eric-would an s5x be the only thing that you would consider doing it right? Or are turbo setups also good options?

[golde30]

Evo3 is cool, but its not fast. I raced an evo3 spec m3 owned by a millionaire, and I walked on him with a bone stock s50. He was not happy, at all. For the money spent, he coulda had a euro s50b32.

The m30 and m50 are very close in weight, and I actually think the m30 weighs only 20lbs more. The m30 puts more power down than an m50. Biggest downsides are the old tried and true technology it posses, the gas mileage, and the look. Oh and you need a new tranny

You should bring it over to Dan's shop if you want serious upgrades. Sonic Motorsports on El Cam in roadnn Mountain View.
