sorry didnt see your question last time im up north hartlepool.bss325i wrote:As I asked but got no reply, what is your location h2ggv?
Im not expecting to fix it with a 8 pound part the car still drives fine just has a 3 min holding back stage like something is stopping it.pacerpete wrote:bss325i wrote: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
might be that wonder why the 320 inlt is on it tho text adam again no replySpeedtouch wrote:Sounds like it may be an issue with the cold start map, quite a common problem with aftermarket engine management installations.
My Tech 2 325i Sport had Megasquirt fitted by its PO, and had such issues, but once up to temperature, was OK.
I suspect most tuners concentrate only on achieving the best performance with the engine up to temperature, and ignore the cold starting requirements!
cheers i will order that new pipe see if that does anythingpacerpete wrote:The 320 inlet will hurt power but it will NOT cause intermittent running issues. Air leaks are the biggest cause of poor running on most engines, standard or modified.

What does it read when you suddenly open the throttle wide?
There's still the mystery of the 2 litre inlet manifold.
cheers will have a look see what i can find thanksSpeedtouch wrote:You could probably use the standard 325i one; it's also used on the M30B35, which knocked out 220bhp, so should suffice for your engine.
Perhaps your existing BMW one is kaputt...
I will have a good look in the morning see what i can see.Brianmoooore wrote:There's a BMW FPR on the fuel rail that can be seen in the engine bay pics. Vacuum port is just left open, and presumably the fuel return port is blanked off somehow, otherwise it would be leaking fuel.
Sounds like he already explored that avenue...h2ggv wrote:Tried to run the normal fuel pressure reg if that's what its called disconnected the red one but once the car was all back together it wouldn't run. so had to connect the old one back up.
yep took it off it look fine to me still wont startSpeedtouch wrote:Sounds like he already explored that avenue...h2ggv wrote:Tried to run the normal fuel pressure reg if that's what its called disconnected the red one but once the car was all back together it wouldn't run. so had to connect the old one back up.
I wonder if he has an eta block with a 2.0 head and inlet mounted on it!Brianmoooore wrote:There's still the mystery of the 2 litre inlet manifold.
Why would this or just the manifold still no answer of the original ownerQuaser wrote:I wonder if he has an eta block with a 2.0 head and inlet mounted on it!Brianmoooore wrote:There's still the mystery of the 2 litre inlet manifold.
The car was originaly a 325i forgive me if i sound daft any location for this markingQuaser wrote:A common engine conversion - easy route to 2.7 engine
Eta block with 2.0 head - if it was a lazy conversion - the complete head and manifold may be used instead of upgrading to 325i manifold - check the casting on the head - is it 885 or 731??
Speedtouch wrote:That'll probably be an '885' head then - there should be an '885' stamped on there somewhere, near the 2.5 circle.
