The sport I picked up yesterday on going work

[h2ggv]

Thanks guys been having a look over the car and sdomething stange going on with the airbox plug and a split in the rubber tubing i have taped it up for now but i am not likin g the wires joined to the plug on the airbox any reasons this has been done.

That said had the car out for a drive struggerling for a few minutes then its perfect and it pulls like a train just holding back for the 1st 5 min

[Speedtouch]

Perhaps the PO fitted a Miller MAF or similar, and cut the wires to the AFM. You also have an extra air temperature sensor going into the side of the airbox.

The split trunking certainly won't be helping things!

What management is it running - standard Motronic, or standalone/piggyback ECU?

this taking form the sellaers add

M20 2.8 stroker with up rated injectors and cam. Afm delete and uni Q piggy back system on ecu. Running 210 BHP. Fully fitted by circuit motors. X2 Computers.

makes hardly no sense to me recipes are here for thousands he has spent on engine work

[Speedtouch]

I'm guessing the "X2 Computers" probably means the original ECU + the piggyback one.

I'm somewhat intrigued as to why the AFM wires would have been cut/spliced into if there is no AFM; perhaps the wires go to that extra air intake temperature sensor on the airbox, since the AFM has one built in, so if they removed the AFM, they would have had to wire in a substitute.

It had a nasty uni Q unichip bodged in by a well known tuner and when the car was with me for work i suggested throwing it in the bin and reverting back to a standard motronic set up with the AFM and get a suitable chip.

Adam then got Paul (paulshepps on here) to map it and got knows whats happened since.

Replace the split intake boot and see if that improves it but as i said to Adam, ditch the Uni Q shite.

Well known 'tuner' beginning with B?
Had one gashed in mine when I bought it years ago- got ripped out pretty quickly- crappy things

All that money spent but essential parts like a AFM boot is split.

No not bexleys.

[h2ggv]

im thinking that might be the way change the full lot from manifold back air box all the pipes and a new ecu.

That would be better if i could just buy them parts new gaskets as i can fit all that.

The car once warm is quite fast but just want all that shit out the way.

could i just change all that and ecu and off i go?

Why don't you just build a nice fresh m20b25 with standard everything

Selling all the leftovers would easily pay for it and you would have a better car in my opinion

If you really want some extra zing, build a simple 2.7 with a road cam , lighten fly, bbtb and chip. Lots of fun to be had

Thats what I would do

im not clued up on all that mate i wish i was if i can get away with the manifold and other stuff i would be happy with that

[jimbom30cab]

Mate, its easy, seriously buy yourself a complete 2.5 from one of the sound traders on here, the complete engine with all the bits. Many traders here will even provide a warranty.

Then take it all out, swap gearbox etc, fit new engine , set to work

All the info is on the net and wiki here

[bss325i]

What is your location?

i understand what your saying but if its something daft with mine its always a option i suppose.

i do like the power that the car has now just dont like the doddgy wiring and different parts

[Speedtouch]

Which ECU do you have? It's probably possible to refit an AFM and just fit a suitable 2.8 chip, removing the piggyback setup.

that sounds a good option take it my car at the min has no afm i would like to fit and the correct manifold and a afm ect ect

sorry if i sound daft its all a learning curve for me owned about 10 e30s too

[jimbom30cab]

Thats worth a try, put the standard b25 intake system on with a standard dme 1.3 loom, then add a chip to the correct ecu

Make sure the 2.5 inlet comes with standard injectors and fpr

dme 1.3 loom??? now im lost agin

[jimbom30cab]

Any 325i facelift, basically F reg onwards

[h2ggv]

Any 325i facelift, basically F reg onwards

why would i need to change the loom??

so i need the manifold set up then all the other parts to the airbox i wish one of yous guys lived local.

cheers for all the help

[jimbom30cab]

Changing the loom puts it back to standard, a known unbodged baseline

Or just sell it to me LOL

[Speedtouch]

Your existing loom should be OK to use - just tidy up the AFM wiring. And yes, your car appears not to have the AFM fitted.

Theoretically, removing the AFM when using standalone management such as Megasquirt makes it less restrictive, but quite often leads to the issues you describe of the car running like a pig at low speeds!

I suspect this is down to the venturi effect, whereby a 'restrictive' (narrow) inlet tract actually increases the air speed, leading to better bottom end torque.

Its starting to make sense now the wiring should be ok with the other plug off and heat shirnk.

whos best for all the parts i would need and a price cheers

dont wanna sell it sold my sport last year and wish i never.

This one handles like it is on rails and the power is nice but the feel for the car handling wise is great

[B7]

I have 325i inlets available if you need one.

[h2ggv]

I give up.

why do you give up?

[Maxtek]

i f00kin love this place ,just l@@k at all the help in 2 days ...

What bhp do standard M20B25 injectors go up to as you may need a custom chip to suit you uprated injectors rather than a generic chip for the standard ones.

Haha how did you guess?

[jimbom30cab]

Hi h2ggv

ref your PM, I would talk to Barry BSS325, on here for supply and fit of all the bits you need, he did offer his advice earlier.

[bss325i]

As I asked but got no reply, what is your location h2ggv?

[pacerpete]

As I asked but got no reply, what is your location h2ggv?

Oop north and he doesn't want to travel.


Adam spent / wasted many thousands on this engine build / set up.
I assume it did run and drive alright at some stage.

£7.86 spent on manky used bits and some hot tips from some of the zone experts are unlikely to solve the OPs issues.

The car needs to go to somebody familiar with what has been done, ideally the person who fitted / optimized it.

PS I wonder how many PMs the OP has had from benevolent zone types offering to solve his issues by swapping him a standard 325 engine for his pile of troubles
