Beemerlad's M52 Chromie

A days work then?

[Daf318is]

I've got my brother hopefully coming up this weekend with the old man's welder so we can get an exhaust system sorted.

things still to do...

1- fit some new front flexi pipes ( I am sure I must have put the calipers on upside down on the wrong sides at the front as the thread for the flexi pipe is at the bottom on the calipers the way I have them fitted and the hose won't reach with the suspension not under compression)
2- fill & bleed brake system and check for leaks
3- fill & bleed cooling system
4- finish off wiring for electric fan
5- tighten up all exhaust manifold nuts
6- refit front ARB and lower the mounts slightly to clear manifold down pipes
7- test all lights etc and align front headlights (euro ones)
8- refit interior
9- shorten gear selector rod
10- general check over
11- refit washer bottle and other general shizzle under the bonnet
12 - couple of burnouts up and down the road

I think there is more to do on my car and I'm using it daily ! Shouldn't take long to do those little jobs now Lee!

[E30BeemerLad]

what do folk reckon about the need to use the x pipe which came with the S50 manifold?

If I can get away without using it, the job of welding the systems together is much easier as all i would need to do is lob off the front part of the 2 part 325 system I have.

Bits of pipe have just arrived from Jetex

[Daf318is]

Leave it off - simple is always best!

[Jhonno]

X-Pipes work though..

[Daf318is]

X-Pipes work though..

What exactly is this x pipe? And what does it do? I was under the impression it just crossed to the opposite side of the car

[Omi]

Also known as a balance pipe, it's a deliberately placed collection and turbulence-inducing section of the pipe designed to keep 'banks' with equal backpressure... Can also have a slight venturi effect, helping scavenging in conjunction with the backpressure. The torque curve can be shaped very slightly by it's location along the exhaust also. - In your application, Lee, I don't think it's really necessary at this stage. - You can cut your bodge out later and get one put in.

Mine has a fat Y around the factory distance, with the large diameter single pipe I already had from Blue Flame... AAS in Newcastle say this should work largely the same as a H/X pipe as they've dyno-tested 6cyl WTCC before to see if they could get away with the cost/lighter weight of a single titanium pipe rather than full twin system.

Cheers I wouldn't have thought it would make a huge difference to Lee's application seeing as the mani is off a different engine anyway but who knows!

[E30BeemerLad]

I may just go with the easy option as the down pipes from the S50 manifold end just near the driver side lolipop bush, with the stock 2 piece 325 system this routes itself along the driver side of the gearbox, so I'd just have to chop it where the S50 downpipes end and weld the f'ker up.



As said, I can use the x pipe later on if I feel it isn't working well enough but it may end up a single pipe system in the future with a rear mount turbo instead of a back box

[buster]

LEE, i didn't bother with the x pipe and still managed more than standard torque when dyno'd.

[E30BeemerLad]

Well little brother is on his way up the A1 as I type this, I've told him to bring one of his spare CT26 turbos from his Supra collection, just for measurement purposes of course

[DanThe]

Ive never bothered with an X pipe either, even on my latest exhaust which is a lot better than any ive done before.

[E30BeemerLad]

I think my X pipe will be donating the flanges and getting welded to the 2 pipes from the 325 system

I've used that excuse in the past - doesn't wash any more I'm afraid!

[E30BeemerLad]

well we have an exhaust system and a functioning gear selector.

Tipped £5 of juice in it and it starts but idles like a complete pig.

Hunts up and down, so think I'm going to have to start searching for an air leak or something.

Any M50 experts got any suggestions? I can't recall making any changes to the wiring or plumbing since I started it and let it tick over for 10 seconds about 6 months ago and it didn't idle dodgy then.

Any tests I can perform?

[Cook318IS]

will the ecu need to re-learn its fuelling if its been unplugged for so long?

[E30BeemerLad]

I don't know if these learn and it ticked over OK when I started it last sept after the rebuild

[monkey]

possably just a sticking idle control motor it may well get better , if not just clean with carb clean and oil with duck oil / wd40 . i found that to work on mine as the engine was sat around for a few months before i fitted it .

[E30BeemerLad]

disconnecting the ICV made no difference so it's possible it needs a clean up

[monkey]

probably just stuck or slow to move from not being used , cleaning couldn't hurt anyway .

[E30BeemerLad]

giving it a quick clean doesn't seem to have made any difference, I've started a separate thread for this problem in the engine swaps section

[E30BeemerLad]

Couple of pics of the exhaust effort
Welded the flanges from the S50 x pipe onto the butchered 325 2 piece system



It all sits quite nicely in an OEM kind of way and it's quiet

Coming soon(subject to engine behaving itself an N/A form)

At least the jap cars in the fleet are in working order

[jimerilo]

Good work Lee

When did you get the Supra?

James.

[daimlerman]

Come on Lee,just run 1721miles around Scotland in mine....

[E30BeemerLad]

Supra turd is my brother's, looks like shite but goes quite well

[E30BeemerLad]

Good work Malcolm, I'll get there eventually

[Omi]

Supra turd is my brother's, looks like shite but goes quite well

About the same as my M52 at the Pod...

[E30BeemerLad]

Not any more, there's a rather big snail about to get attached to it, but yeah his chips got pissed on a bit when you were running same/ better times at the pod

[E30BeemerLad]

Small update

Filled the PAS system tonight and then introduced some coolant to it, was a nervous experience filling a dry system from scratch, took ages before there was any heat coming out of the vents. I'm pretty confident I've got sufficient amount in the system. The thing is still idling like a pig, disconnected the ICV and it made no difference, so hopefully the replacement item that is on the way will sort the job.

Also got to figure out how to get the lambda sensor out of the manifold. There was 2 on the system. One on a downpipe and one on the x pipe. As luck would have it, the one which I have kept which is on the bottom of one of the downpipes is a different connector to the one on the car loom, the one which was on the x pipe has the right connector.

The blow torch was needed to get the lambda out of the x pipe. Trouble is there is naff all room around the downpipe to get a set of stilsons on, so I have 2 options, either get the soldering iron out and splice the correct connector plug onto the existing lambda sensor, or butcher the sensor so much that I can get a 21 or 22mm deep socket over the top and hopefully remove it, hmmm

I am an utter spastic and have put the front brake calipers on upside down on the wrong sides, so they need to come off and be swapped over and I need to get some new front flexy hoses.

She's getting there

[Dezzy]

Lee i fit exhaust for a living and lamdas are a twat. If you can get a 22mm spanner on and give it a few good licks with a hammer you will have a better chance than with the oxy. If you do warm it dont get it tpp hot. They are a fine thread and tend to all become one big mess with no threads left with too much heat. Shock is my first port off call with these little tw*ts

[E30BeemerLad]

cheers fella, I'll let you know how I get on

Sorry, forgot to unwrap those cams and have a look for the numbers for you

[Dezzy]

I need a higher rofile than shrick will do for me mate on standard internals and cats are £688 so think i am going to get kent to re profile mine for about £350. What do you reckon to kent cams? I have only herd good thing

[gcs325i]

How come your not running the powerflex bushes in the m3 position? and the exhaust looks good by the way.

Kent are a well established brand, never heard any bad news mate, it makes sense.

What duration are you going for? Yours is a non-vanos lump too isn't it?
