e30 M50 Manifolds

[DanThe]

If I had a tig welder id be on a refresher course and investing in a pipe bender quicker than you could say one thousand pounds

[Jhonno]

Bash them out at £800

[Mattp87]

well moan about them copying...but to be honest what other options are there...ship a rhd e30 to belgium to make a manifold??
and if your after 8BHP more spend 3x the price but most people want them to get the engine running in the car, not for power gains??

hot tuning have not confirmed anything since anyways...but it is christmas i guess!

[DanThe]

That louise bird is on holiday so any response will be delayed

[Mattp87]

thts what i thought, dont have my car...or the engine atm so having a manifilds hardly a priority.

Barry,climb down from that high horse of yours,do YOU think that I would have put £200 of my hard earned into something that does not work? I could not justify £650 on a BTB2,but was prepared to try £200,and I stand by my 'arse dyno' claim that my home brewed 2.7 runs better and uses less fuel(read runs more efficiently)with the hottuning manifold than it did before fitting.Pre fitting I was returning 31.5/33mpg,after fitting the Hottunning manifold this has improved to 34-37.5mpg.If you doubt my fiqures,check with those zoners we holidayed with in Scotland last April,they saw the OBC numbers.AND my car left the standard 325i's for dead climbing the mountains,I was not hanging around.... would suggest you join us next year and prove your claims.

I've proved the Facts Malcom have you? No.

You forked out £200 because £650 was to expensive for you. How did you know the HT one worked?! No on had proven anything untill Simon posted his before and after results.

Of course your car should leave standard 325i's for dead, ITS A 2.7!!

I'm not on my high horse, i'm just coming back "all guns blazing" at all the people who slated the BTB2!

Read my post again,Barry,all the facts are there.If my engine is using less fuel,it is more effiecent.Fact. Anyways,this is a disscussion,NOT about hottuning v BTB2,but about weather or not we can get hottuning to manufacture an M50-E30 manifold. I have confirmed that my welding skills are not really up to the task,and my wallet is not really up to the Fritzbits item,so a sensibly priced alternative is required.My M50 conversion is much the same principle as my 2.7 conversion is,I am looking for modern engine design fuel efficency more than outright power,this touring that I am playing with I plan on being one of the cars I shall be using in my retirement,yes,I am that old!!

The bottom line is that you jumped on me for putting the HT mani down.

Your facts are about what?! Fuel economy readings on your OBC?!

What is the priciple obective of a six branch manifold?! To gain more power, not improve fuel economy! This may only be a bi-product, not what this particular item is designed to do.

FACT is i've proven the HT to be the poor imitation it really is and now that i'm trying to inform everyone of my findings (this is what this forum is about after all!) so people dont waste their hard earned money on something they think will give them more power when it clearly doesn't, some people dont like what i'm saying because deep down they know they potentially have wasted £200-2500!

Dyno your car Malcom and lets see if it makes more than the 189bhp it did at that BMW5 forum RR day we attended.

I would like to see some more before and after results for the HT mani!

[daimlerman]

Please keep on topic!!

[bss325i]

Please keep on topic!!

But it is on topic!

Someones approached HT to do an M50 manifold so other products they have made is relavent.

I have said all i need to say on the subject, i'll let the facts do the talking from now on.

[DanThe]

I can just see Barry's forehead pounding away as he types


HT 6 branch may be a poor/cheap copy of a properly designed/manufactured one but isnt that the good point? So we can have someone to produce a cheap off the shelf manifold that will bolt on the engine 'and' a 325i system?

Without cheap copies/imitations, how many of us would be using computers, or watching christmas crap on widescreen.HD ready/bluetooth enabled tv sets.. There is expensive, and there is exorbitant.
Best part of a grand for a manifold, is it made from the Gold Gordon Brown knocked out ?

But it isnt on topic because this is about making the conversion easier and cheaper, NOT making power out of the engine.

so theres about what 4 people interested?

[Jhonno]

Surely that is the point of the conversion?!

It isn't making it cheaper either..

Maybe but if it doesn't perform as well as the original then whats the point?

BTB2 for M20 engines is £638 not a grand.

There is no m50 original straight fit to preform against and some of the modified efforts I've seen posted don't look that great as it is.

[Jhonno]

If you mod the steering coupling you can use the standard manifold..

I was talking about the M20 manifold.

I can see a point in having a a manifold to use as a straight fit when using an M5x in an E30 but HT need a manifold to copy!

[gcs325i]

Ahh I've only seen modified non cast manifold and down pipes.

[Mattp87]

its cheaper than buying the btb2 manifold?

[bss325i]

If you mod the steering coupling you can use the standard manifold..

Is this what you did?

[Jhonno]

No I'd already done mine the 'standard' way when I found this out..

[DanThe]

If you mod the steering coupling you can use the standard manifold..

With an E36 rack? I dont think so, and its not really going to line up to an E30 325i system is it, there is no 'original' as such, the done thing is to chop and weld a pair of M52 manifolds which means no two cars have the same gas flow rates

[eko]

I know of atleast 3 M50`s using solid/modded couplings with no problems

[DanThe]

With untouched manifolds and E36 racks Tony?

[eko]

With untouched manifolds Tony?

All have been chopped to clear but not as much as when the standard coupling is kept.
To be honest I think they would clear but would be very close fit,too close for comfort?

[eko]

Mine and OBs are with 36 racks the other is standard E30.

BTB2 for M20 engines is £638 not a grand.

Yes, but their e30 M50 manifold comes in at a grand.
which is what was being discussed here. Also Frizbitz at £750 to 800.

[Jhonno]

They dont do an M50 manifold.. They do an S50 manifold

[daimlerman]

They dont do an M50 manifold.. They do an S50 manifold

This was another concern I had,the Fritzbits fella was claiming on the 'phone that M50/S50 'are just the same manifold requirement' if I am spending £750 I need to be sure the thing is correct for my application!! I have not spoken to BTB,but I am informed that it is nessesary to be sat down at the time...£1500 is the rumour I heard,just for the manifold. These prices sent me back to the garage with renewed determination to create my own 'masterpiece'.As I wrote earlier,if Hottuning,or anyone else,can come up with a sensibly priced manifold,I will be at the head of the queue.

12345kevin has an M50 and a Fritz mani, speak to him.

So, out of interest, how much is this manifold ?.

It,s ok , i,m sitting down.

[Jhonno]

The M50 and the S50 have very different sized exhaust ports, and one manifold which is optimised for one, wont be for the other

£1k is the figure from BTB I believe, or just over now..

Hayward and Scott did a complete manifold and system for £1500 for Karan's S38 chariot, which is the same that they quoted me for an S50 setup..

Dameon payed just over £2000 for the BTB manifold and system for the S50'd touring i bought from him.
