'only' 600hp good luck be sure to post pics after tabooing

Ive done quite a bit of research on a remote mount turbo, they do work but you do suffer a bit in spooling time/boost see at the throttle body. You have to run a oil pump and a decent one runs 250+$. Also alot of the time I see v8s/v6s merge the headers and then bring the exhaust back up into the engine bay for the single turbo.

Good info Jgood.

I've been doing ons of research on turbo'ing my m60 and most of it is pointing me in the direction of a rear mount. Deleting the spare tire or even cutting it up to use it as a housing will be much easier than squeezing and fooling around a tight 90 degree engine bay.

This fall I will be installing AC in my car as well so there's that.

Another plus for rear mount will be the fact that you'll need either no intercooler or smaller volvo/audi/saab type intercoolers that will fit in the brake ducting area.

The m60/m62's will need very good tuning so more research on management is a must. There is never an easy answer to these type questions.

I've ordered all my stainless exhaust and will be building a pretty much bolt on style system. Getting my management setup and tuned NA will be my main priority.

I was previously interested in a remote mount turbo, and posted a bit about it a few months ago. I came to the conclusion that it wasn't a great idea (for me) for a few reasons.

1. Not only do you have to plumb extra piping, but you need to plumb oil lines too. And since the turbo is so low and so far away, you'll likely need a scavenge pump so you don't kill the turbo. Lots of extra critical parts hanging on the bottom of an already low car...

2. Exhaust gases are much cooler, and therefore slower moving, by the time that get to the muffler. You'd either need to reduce the turbo compressor side size, or the exhaust pipe size. Still, it's going to take longer for the decreased exhaust pressure/velocity to start spinning the compressor wheel.

3. The charge piping is much longer, and will have a bunch of bends to get to the throttle body. You'll lose considerable boost. Maybe up to 5-6 PSI if you're trying to run 10-12. Turbo and piping sizing becomes extremely important, and you'd really need to experiment.

4. All that charge piping, all of those connectors and clamps, inches off the ground. I think popping something on the charge side would be a frequent occurrence.


Here's a good post from someone who experimented with a rear mount setup. He had access to a dyno, lots of knowledge, and parts to swap, which most of us don't have. You can see what kinds of issues he had, even with a kit designed for that car. Imagine what you'll come across building your own!

Also plenty of room for a supercharger if you want something more streetable and less likely to murder you. May not be able to use the ESS/VF e34 kit brackets, not sure. I'm trying to figure that out still.

Pretty neat to think that that car is now this car ....

Oh lord, the sound a m60 must make with a turbo. I want.

Maybe I need to retract my statement about the twin turbo being too difficult... I didn't realize there was room for a bottom mount turbo on the drivers side. Here's a guy who did some amazing work to get a twin turbo m62 in his e30. (link is translated)

I think I'd still do a single turbo, but now that I know there is room for a bottom mount, that is the way to go! Just pipe the drivers side over to the passenger side. Seems like it would be way easier then a top mount. Just throw together a log style manifold for both sides (very easy) and pipe the exhaust out right where you normally would for an N/A m60, modifying the engine mount arm as necessary for clearance. Much better then trying to run a 3.5+" pipe over the wheel housing and around the strut tower.

Now I'm tempted....

STS style twin tarbo. Fuel cell it and put the tarbos where the fuel tank was.

Sure, more piping, lag, etc, but when it hits, you're fucking dead anyways.

[bradnic]

holy shit.

justin are you gonna SC your M60?

[MJCRO]

Holy crap. I take it back, go for it OP.

But hmm, very interesting. This gets me thinking to do something with B30.

No one on here has turbo'd or supercharged an M60/M62 in an E30 (at least not that I've seen any).

There's a bunch of both. Plenty of room.



A single turbo is going to be FAR easier. There just isn't room to get a downpipe out the drivers side, unless you want to just pipe it out the fender (that would be amazing, don't get me wrong). Best bet is a single turbo on the passenger side, pipe the drivers side over in front of the oil pan. Then the downpipe can go over passenger side wheel well, down through where the battery tray is and out the back.












That guy has wheelspin in 6th gear.





Also plenty of room for a supercharger if you want something more streetable and less likely to murder you. May not be able to use the ESS/VF e34 kit brackets, not sure. I'm trying to figure that out still.












You could do an awesome stealth mode setup and put a S/C where the A/C compressor would go.

When are we doing beers / Gentlemen Jack?

Is it this week or next week?

And yes, I'm a cnut, but I'm a good cnut.

Next. Gis email, will add it to list.

There is a white s62 twin turbos floating around but not much documentation. Im only looking for 600 hp with is easy with a single turbo I know. Ive been reading on twin sequential turbos one and one big to help spool the bigger turbo and help with the lag. Plus the fact that not many have done it makes me what to
