B C Posted December 2, 2012 Report Share Posted December 2, 2012 if you are like this guy and know what you are doing you could have yourself a reliable turbo m20 with little lag that screams on the track.A turbo M50 will make a little more power with less boost than an M20 and might be the better choice if you want to keep the internals stock.If it were me I would probably do the M20 just because I feel that if the heat of the turbo caused a cracked head or if the bottom end blew out, another healthy M20 engine could be dropped in for hardly anything.

Rowleym Posted December 3, 2012 Author Report Share Posted December 3, 2012 Aaah. So I have to pay 800$ for my sisters laptop to be fixed. I really need some persuasion. Is there any stock piston/rod/crank setup that would get me some damn low cr? Like around 7? Still might go m50 but I don't know yet.

Rowleym Posted December 7, 2012 Author Report Share Posted December 7, 2012 Little update. Bought a m50nv. 130k on it supposedly. Need to track down an oil pan and stuff. Also sold my hx35 to GunMetalGrey, and he gave me a swap brace. Pretty excited. Cool dude. Quote Link to comment Share on other sites More sharing options...

Nick_08 Posted December 7, 2012 Report Share Posted December 7, 2012 (edited) I'm a little late on this post but, a stock m20 with stock head gasket, ARP's, stock intake manifold, and hx35 12cm will easily give you 400+ whp (with a good tune)...It's proven to handle 1 bar (350whp) all day long. If you grenade it, no big deal.Also, TB size doesn't really matter when FI. Most either o-ring or weld, m20's weak point is the head gasket pushing out into the coolant channel. Specifically cylinder #6 (hottest). Unless you plan on detonating, you wont get far. GL with your new m50.

GunMetalGrey Posted December 7, 2012 Report Share Posted December 7, 2012 M20 on a stock head gasket will not make 400HP, nor will one without built internals, they take a little bit of boost alright but they don't make much power per lb of boost.

Ryan... Posted December 7, 2012 Report Share Posted December 7, 2012 If he's got the same car as I last remember, Nick's been running a boosted M20 for some years now. I dont remember the details anymore, but I almost bought a kit off him in like 08 for my bronzit sedan Quote Link to comment Share on other sites More sharing options...

Sent from the future. Or my phone, who knows. Not trying to thread jack OP I'm also not sure if it's against the rules to link another forum but here goes... Here is just one instance. I know he isn't using the stock head gasket but he is using shitty MB head bolts AND stock internals...93 octane. Stock motor w/ 208k miles. head was rebuilt @ 185k (valve job minor port cleanup stock cam/springs) Metrick Blue bolts and Cometic MLS boosted for over 20k. 437whp/380ftlbs on 20psi http://www.e30tech.com/forum/showthread.php?t=112167 This thread has a couple turbocharged m20's (with dyno charts) slightly different setups. A lot of them have stock m20's pushing 400whp easily. http://www.e30tech.com/forum/showthread.php?t=113066&highlight=m20+turbo+dyno&page=2 It's been done and proven... Again OP, GL with your build.

Rowleym Posted December 8, 2012 Author Report Share Posted December 8, 2012 Im totally not against m20's in anyway, and I'm totally open to constructive thread jacking. Thanks funny. I had an hx35 12cm and literally everything else to turbo my m20, but for some reason, I went m50. I think basically because for the future, I want to be making big power, and I think that the m50nv is a pretty good base to start? I also like higher revving engines. Welding my head+Oring was over 400$ at my machine shop. Not only that, but I had to pull the engine anyway, so why not buy an m50 for 300$? All i have to do is arps, and mls for a decent 400. I dont know. I'm not saying anyone was right or wrong. Quote Link to comment Share on other sites More sharing options...
GunMetalGrey Posted December 8, 2012 Report Share Posted December 8, 2012 A LOT of other stuff goes with putting in a turbo, I have a pretty good link selection going on right now for all the feed lines, oil blocks, return lines, fittings, injectors, all kinds of crazy freaking suff.If you have any questions with the swap or anything else for that matter do let me know, I have done it a few times now Quote Link to comment Share on other sites More sharing options...
Rowleym Posted December 9, 2012 Author Report Share Posted December 9, 2012 The only thing i have left to buy is intercooler piping, oil feed(I have the fittings), do i need to relocate the oil filter? Most people did with m20's. And i have to hook up my oil cooler. Thats about it. and buy mounts and stuff.. I will definitely let you know though Quote Link to comment Share on other sites More sharing options...
GunMetalGrey Posted December 15, 2012 Report Share Posted December 15, 2012 Get injectors yet? I might have a set of freshly rebuilt 42lb'ers Quote Link to comment Share on other sites More sharing options...
Rowleym Posted January 8, 2013 Author Report Share Posted January 8, 2013 No I have 42lbers. Anyways. Little update I guess? I've been finishing up my Volkswagen recently, and tearing into my father son project. We pulled the tub off the frame in the cj7, looking to buy a YJ tub, powder coat the frame, run new brake lines/fuel lines, rebuild the brakes, add about a 3 inch lift with some fender flares to hopefully put some 35's or maybe 33's. Re-ring and bearings for the AMC 360 coming in, carb rebuild(that was a first for me) and I guess that's about it? I will be finishing the heap before I put time into the bimmer. I have lots of time for the bimmer, but My father and I are taking a trip to Colorado camping when I graduate so I want this bitch to be done. That is all.

Rowleym Posted January 15, 2013 Author Report Share Posted January 15, 2013 Little update. Sold the DIYPNP and wasted spark setup in like 10 hours. Bought ms3x with Jim stim and 80# Injectors. I'll be running cop on the m50 with sequential injection. Me gusta e85 Quote Link to comment Share on other sites More sharing options...

Rowleym Posted January 15, 2013 Author Report Share Posted January 15, 2013 Haha I wish. I'm actually just shooting for around 400, but I'm using e85, so I need around 30% more fuel! Quote Link to comment Share on other sites More sharing options...
