Thanks.

A 325i (885) gasket is the right bore size, but doesn't it have more water jackets? (think I've used the right terminology) Would that effect it? or should I use a 525ee head gasket? It's just that that gaskets come in sets here, and would be much easier just to get a 325i set. (I have the inlet man...

Sorry, off topic, but what head gasket do you use with the 731 head?

Will a 325i (885) one work?

There's one in Australia that I know of.

What about a Lexus V8? Twin Turbo'd.
It's a win-win situation, rice and a V8.

Double post

There's a few options.

To go on an 2.7 m20, think I'd be dreaming if I thought I could make 300hp. Even with headers and Megasquirt planned.
So to big?
They look a little more complicated than bike throttle bodies to. I might have to go down to a wreckers and check some out.

These are from a Toyota 4AGE...

They come in 42mm or 45mm (to big?)
Would it be to much work to add an extra 2, and make these fit?

The reason I ask is that these are reasonably inexpensive here in NZ compared to bike throttle bodies.

I'm in New Zealand

What are the throttle bodies from?
What size are they? (internal diameter)

Thanks
Antony

Individual Throttle Bodies.
What are people getting there's from, bikes?
What size are people using?

Has anyone used some from a Toyota 4AGE?

Thanks
Antony.

Thanks.

I'm taken my 320i into the mechanics this week to let it grow up, and gain an extra 700cc. (using the original 731 head). I've got all the parts (I think), have read HEAPS on the net (sometimes not a good thing, getting contradicting stories), but as I have limited mechanical experience I'm just aft...

New Zealand.

I'm also building a 2.7 in NZ

Where abouts in NZ are you?
Are you on bimmersport?

pics?

We love pics.

Thanks for your help, but thats the throttle body.

AFM = Air Flow Meter, Its the bit attached to your air box. Before the throttle body.

my 320i AFM and my (apparently) 325i AFM measure at 65mm? ????

????

Maybe it's different over here? (in New Zealand)

Hey

Whats the internal diameter of a 325i AFM?

Is there any difference between the 325i AFM and the 320i AFM?

Thanks
Antony.

I'm using the 731 head, forgot to mention that.

So I shouldn't need a vernier a?

Thanks
Antony.

Hey
I'm just building my 2.7 at the moment.

What timing belt are you 2.7 guys using?

i.e: would it be from a 525e or a 320i?

4.0 litre lexus V8.

280 - 300 hp.

Sorry riley, stole your thunder.

Hey, I'm doing a 2.7 aswell, and I was wondering if you need to change the sump, or is the 525e one alright?

late 323i cams are 260 degrees, and 325i ones are 252 degrees IIRC. So yea, 323i cams are better.

a lil off topic.

Is there any difference between the head on a 320i and a 323i?

There both 731 cast, I know the 323i has a different cam (260/260?), But is there any difference in the valve ports/sizes?

How time flies when your having fun

^fixed^

hey. thanks for sharing that. looks like some impressive work. i was almost convinced not to do it, and do an engine swap (which i'll eventually do anyways), but your project has got me thinking again. theres just not that many turbo m20b20 (even if there is a reason for it lol) looks sweet as man :...

different cams tho.

323i cam has 260 degrees lift. so you should get some improvement.

Someone please correct me if I'm wrong.

a guy here in new zealand has one (m42, in an 318is). 165 rwkW @ 13 psi.

and he's selling it here: http://www.trademe.co.nz/Browse/Listing ... =102539106

interesting to see how little difference the 2.7 makes in power. is the '/260' torque? Im sure it that is where it would shine.

has any one got any links maybe about b20 turbo's. it's more of an interest thing.

well my overall goal would be to have a 2.5 turbo (or 2.7 or 2.8, but unlikely as stroker parts are hard to come by/exspensive over here). it would be interesting to put the turbo kit on the m20b20 first, as i get funds for the M20B25. instead of getting the M20B25, and then the turbo:) i'm curious ...

hey (first time caller, long time listener) i was wondering if anyone has turbocharged an m20b20 in a 320i. i know, get a 325i, and turbo that (and thats the plan)...but i'm interested in what results these engines can produce turbocharged. So if you've done it, or heard of any, i'd like to hear fro...
