M30 Turbo update thread ****RUNNING

[billgatese30]

look into those turbos toby.

i'm not sure about the bm's but i know a few of the beetle boys use vw passat deisel turbos on their motors without too much trouble

it could be worth a thought

[Eddy]

Hope U don`t resent me saying: U`r faking mad mate

this is gona tear up the concreate on your street


Hope you finish soon,I`ve been reading this with great respect to the owner

[glenn]

Already thought about that guys

they ought to go for that!

Would need to get the cars to the office in Tinwell (near Stamford) for the photography but could combine with a meet/race

only problem is i need to get mine finished first

when do you think you'll be finished toby?
'cos you could allways pitch them up against a real car

[Toby_Unna]

cheers all

Mr Gates. i'm pretending i didn't see these turbos and am trying to forget about it so don't complicate matters

seriously though. i think they're physically too big even if the wheel sizes turned out to be suitable. i was just tempted for a moment by the thought of a proper garrett instead of my cheap american thing

[Toby_Unna]

speak for yourself glenn! do you have a car yet, or a lovely engine and two engineless e30s

i'd have thought every magazine would want a feature on your car

don't be soft ya big girl

you know it makes sense

[glenn]

haven't made much progress yet mate (weather )
just thought if it was in a few months i'd have got it done by then

[Toby_Unna]

can safely say you've got a couple of months Glenn!

unless my megasquirt decides to build itself

[Jon_Bmw]

Seriously starting to take shape now.

Those turbo's could be Holset Hx40, 45's or even 50's and the americans do pay top dollar for them so you might be able to make some Ԛ£Ã”šÃ‚£Ãƒ”šÃ‚£'s outta of them Toby.

I'd be way to scared to show my ghetto install in a mag so a nope from me.

now thats an idea !

ALL the DIY 'charger e30s in one article........

[Davenotouring]

This is awesome!

Turbo'd E30s everywhere! Turbo'd M30!!!

[kam-325i]

Whats the diffenece then between a turbo for a petrol engine and Diesel engine?

A turbo is a turbo, aint it ?

[Turbo-Brown]

It is and it isn't.

I believe that diesel's turbochargers exhaust housings are manufactured from different alloys to those used in petrol applications as diesels run colder.

Other than that though, if you can find suitable ARs for the housings there's no difference (unless the exhaust turbines are of different materials too)

How's it all coming together Toby?

[Nick_TBMW]

What bout a turbo feature in TBMW

Maybe we can get some timing gear at an airfield and pit it against something really big and expensive like an M5/M6... bunch of Davids and a Goliath

Glenn, get yours fixed and you've got your own feature remember

[Turbo-Brown]

I'd be up for that, can't see my 260ish bhp being much of a match for 500 angry bavarian horses though

[Nick_TBMW]

Well I'm sure we could think of something interesting to stand off to

nick,
i've just been commissioned to carry out a V12 conversion into an
e30 touring for a fellow zoner which is going to take me a few weeks,
and then all my running gear is going into a M3 shell.
so i dont know how long these two projects are going to take me but
i'm not going to be doing much sleeping in the near future.
sorry for hi-jacking your thread toby

um, no probs Glenn

have i fallen asleep and missed a year or something

sounds like your considerable expertise is going to good use anyway mate! no more bronzitbeige 350 though?

[bigdek]

Come on then Glenn

Youve dangled the carrot

Who is the mad zoner getting a V12 ?

[glenn]

i'll let him tell you when he's ready, but i'll be starting as soon as the 750il
get's delivered.

toby,
allway's wanted to have a m3 shell and sorted one out last weekend,
so i'm not sure what's happening with the 'bronzitbiege' at the moment
and your choice of words cracks me up

have i fallen asleep and missed a year or something

[Batch]

I've posted a PM to toby but he has disapeared somewhere so maybo someone else can help me? I cannot decide weather to use 2 smaller diameter exhaust pipes on my 335-to-be or just not mess with it and make a single pipe bigger diameter exhaust? Let's say the area of crossection of the two pipes could be the same as of the one bigger pipe?

[bigdek]

use an m3 system

i used a standard 325 system ( for now )

Job done

[Nick_TBMW]

Glenn - please keep in touch mate

[Demlotcrew]

Im also interested in who it is?

S i m o n from wales?

Andrew

[bigdek]

that who i was thinking also

[Batch]

I won't get m3 exhaust because we have no e30 m3 in latvia, not even one. So the only way is to make it from scratch or modify some stock exhaust. I'm looking 4ward to making one from a scratch.

[Turbo-Brown]

I made my exhaust from scratch, it's not all that bad really

na andrew, guess who?
also wanted to try and quad turbo a v12

[Batch]

So maybe you can answer my question what to do: make 2 pipes of ~stock diameter or (it's much easier) make one but bigger pipe where two pipes from exhaust manifold come togather? Something like stock e30 320 exhaust only bigger diameter (so the area of crossection of the bigger pipe is equal or bigger than sum of two stock pipes crossection areas?)

[Turbo-Brown]

I went for two 2" diameter pipes which follow the same route as the original system, have a crossover in the same place, but only have one silencer which is at the back.

Tnx. Isn't it too loud?

[Turbo-Brown]

Tnx. Isn't it too loud?

It probably would be running normally aspirated, but turbochargers act as very effective silencers, so I have a nice muted burble (at idle anyway, no idea about off idle!)

[Batch]

One day on topgear i saw Clarkson mentioning some valve in exhaust that opens when you press throttle hard, something like this is uset in aston martins. They say that when it's closed the car is normally quiet, but when it opens you can hear the roar even 2 miles away

BMW 330i backbox has this valve

[dazleeds]

my mrs e46 323i also has this in the tailpipes

but havent noticed any change really in sound when flooring it
