Some guys from georgia have made a couple e46s, just arp head bolts, rod bolts and they push 400-650hp. These videos are so nice and inspiring, makes me want an e46 to turbo 😂
@@Sir-Kay arp is a company that makes bolts, head studs are installed in the block, they are stronger than the stock ones, to prevent the possibillity of lifting the head, rod bolts are, as in the name, for tightening rod caps to the rod around the crankshaft… they just reinforce the engine. The “proper” way to boost an na car would be to install stronger pistons and rods, but rod bolts and head studs can be installed to do a “cheap” build, it wont make it as strong as forged rods/pistons but stronger than stock
Only thing that contributes to head lift and overheating is the stock thermostat and thermal switch that bmw used, the car runs a little too hot... changing them for lower temp ones while a radiator upgrade with electric fan is the finishing touch. Then voila no head lift/overheating. (Forgot to mention turbo blanket and exhaust wrap Help more with this, keeping an engine cool while making power is key, why e85 is used as well, cools as it is injected, so yeah, keep spinning the Chinese choochoo boi :) )
true enough! Thanks for contributing useful info. I’m running of course a turbo blanket, I was hesitant on exhaust wrap for the manifold because I’ve seen some warp under the extreme heat (cast manifolds though) although I have sleeves for both the drain and feed, heat taped the engine cover (right under the exhaust) and plan on wrapping the hood dump. I’ll be running no hood for a while so heat soak is greatly reduced. I run my fan once it hits about a quarter on my temps
@@straightsixracing Definitely the right way to go, Even e36 m3 guys upgrade this stuff to make the car last. Also Like you have said before people with unopened engines have made alot of power, reason being the head bolts and studs stretch after torquing, so keeping temps down with a good tune = happy car (Applies to any car). Also I believe those cast manifolds crack because there are no stress relief cuts in the metal, you can do that yourself and they will be perfectly fine. Plus your abs module probs wont die!
Turbo building my E30. I’m 12k £ in right now. Had to buy a M54B30 330i manual. Stand-alone ecu. Turbo kit. And a few other bits. And a lot of labour. Should be done soon then onto tuning. I’m hoping for 450bhp 😁
Very nice vid. I want to boost my M54B30 too, but in germany we have very strikt laws. :( I read you can buy a cooler from like mishimoto so the engine doesnt get to hot.
Dude that’s bad, i wanted to move to Germany and get a masters degree and to pick a car and work on it at spare time, reading you comment blowed it all off
from what i've read / seen, theyre so strict, but there are companies that make legally modifications, but they are very expensive because they had to go through a long process to make them legal.
Love the video and the insight on turbo-ed E46. I own a 325i, love the chasis, but looking for a little more power. This is definitely the route I'll be taking. Thanks :)
I know this vid is 5 yrs old but if anyone’s seeing this that has a turboed e46 what oil are yall running ? Haven’t really heard or seen many people talk about this
I’m about to do this to my 05 330xi. Do you think I should beef up the axles first? It’s very reliable, but I also know that more power=more problems…. What are your thought?
Ok so what need some links or a video reference for the m50 intake manifold swap on m54 engine, I’d prefer to go with an aftermarket one instead of the one one. Thanks in advance!
yo hi man, i know this video been uploaded a long way ago, and i saw u saying something about m5425 block with m54b30 internals, is that for real? i mean in the country i m from, taxes for big engines are hella expensive and i was thinking to put the crankshaft, roads, pistons everything from the b30 in the b25 block. about the head i m thinking the b30 is the way to go. what u say? it s possible something like this?
Le 6 cylindres bmw adore le compresseur bien plus simple qu un turbo a installer le régler et tout un compresseur tu le monte et tu monte la courroie point mort aux
so you would say the e46 motor despite running high compression is turbo friendly? considering low boost. I would love to turbo my 330 im not looking for crazy hp
I am curious, after setting up a turbo on your car (it does not come with a turbo from factory), is it possible to make it street legal? Here it is impossible to pass the annual car check up even if you have a CAI
Illinois is very lax we only have emissions and I exempt myself from that, other than tickets by police(which I’ve never had even though I’ve been pulled over) there’s no enforcement on modification in Illinois as whole.
4 thousand i can do this for about £1500 n thats buying a standalone ecu aswell n few other parts as this is what im going to be building just have to search for all the parts needed
honestly i agree, but things add up fast, i say if you can set a larger budget and have extra money when youre done go for it, thats what my whole build is about :) also i cant weld, so some extra expenses go there
For all the main parts needed plus a surge tank and fuel lines and few other little things all my prices came up to £1401 but urs is a cool build man love watching your videos
3Timese46 I’m a lucky guy ahha! I’ve been looking around for a while, always on Facebook searching, a local page there was an e36 for sale and it included the kit, so I asked how much he would want for just the kit, he said 450. I said I’d help him find a buyer if he’d take 350 and he said alright! I sent the ad around and tried to get people to buy the car, he was cool he also gave me an m50 intake manifold, m3 e36 axles and some other stuff with the turbo kit for $350.
So it believe the m54 already has an MLS gasket (unlike m50 and m52) but the studs/headbolts are torque to yield meaning the fastener is stretched a measurable amount. One thing with boosted engines is they can knock or predetinate witch causes peak cyclinder pressure to go way up and can over come the stressful of the fastener or the aluminum threads in the block. Studs are a must, the stock one are inadequate for anything over 8psi they are easy to bur in to you only have to remove the valve cover. Sure you can get 600hp on a stock motor if, it will lift the head soon enough
@@chrisrobinson7395 ARP is the only company that really makes aftermarket head bolts it's actually a stud conversion instead of bolts and they're reusable they're also 12-point instead of 6 which means they'll be less likely to strip and be able to handle higher torque loads I believe the stock torque to yield is 90 ft lb with 180° and these handles something like 130 or 140 ft lb to be charged properly so that right there says something about the clamping force of the head to the block
Catastrophic effects? More than likely not. Reduced MPG, reduced longevity of cats(if still on the car) and possibly more chance of carbon build up. Overall If done correctly, a simple “pop” tune (fuel overrun enabled // injectors spraying extra fuel AFTER throttle is closed) isn’t harmful but does have some minor negative effects. If you mess with ignition timing, there can be loss of power and more. I had a burble / pop tune on my e46 naturally aspirated for a while, gas mileage wasn’t significantly reduced, more than likely me engine braking / revving more caused it. If you want it, go for it, I know many new cars (Ford Focus RS, Mercedes C43 etc) have a sort of burble tuned from the factory.
I ran cats with an aggressive burble / retarded ignition and I pulled them, weren’t blown, drove/ drifted with that tune for months, it will eventually kill your cats, I was more worried about them overheating and starting on fire lol.
600whp unopened is horse shit. 450whp mark even m50/m52 ringland fails, e85, meth, whatever. b30 ringland and piston design is especially prone to this due to bad oil ring design. bullllllllshit
I've learned from owning a 04 zhp. To get a 93 Honda civic hatchback, get a k24 motor throw a turbo on it and you will make more power then what you would of made with the bmw
