I actually had a gap between the injector and the intake hole - hence filing it down so they sat inside. A gap would mean unfiltered air etc getting in. Guess it depends on the car/set-up.

Glad it worked though!

Ok, back with some updates on the situation. I was out of town for a week with work so I couldn't test the car in all aspects. Last night I had a few runs with two of my friends, both E36 320i. One of them has the engine running perfectly with 15'' alloy with 195/60. The other one has problems with vanos, the engine does not run very well and has got 17'' wheels with 245 tyres. We usualy run from 50km/h to 180km/h.

Before the swap, I only ran with the second one, that is not working very well and has got big wheels. It used to go 3 car lenghts ahead. Last night we were perfectly equal two times till 160km/h, and one time my nose went ahead went ahead 2-3m at 180km/h.

With the first 320 that was properly running he went ahead 2 car leghts, I do not know if the car has resoft or any chip. Probably not. I wonder what the difference would have been before the swap. Shameful I guess

I still dream to the day when an M42 will beat a perfectly working straight six, of course without supercharging it.

I just installed these: 0280155710

Straight fit and very easy to install - even for novice like me. No signs of leaks (about 300 miles).

I bought them off ebay (remanufactured) and didn't realize I bought 8 instead of 4. So, I have 4 extra. Who wants them? (Asking $40 shipped in US or barter). PM me if interested (I don't always check forum, but PM will prompt me to immediately).

Any trick to separate the fuel rail from the injectors? I have the Fuel rail and lower intake manifold off the head and just thought I'd ask before pull the injectors and rail off. I should have a set of eight 155 700s coming this week (only need four) and taking the time to replace hoses and clean things up before they get installed.

I did pull the retention clips for the injectors, but don't know if there is anything else holding the base of the injectors in other than the friction of the o-rings.

Thanks!

Rich :cool:

As long as you have removed the small square clips holding the injector to the fuel rail, it's just a matter of pulling and twisting harder. Hold the fuel rail with one hand as close as possible to where the injector is attached.
good luck

Thanks Justin! Drinks are still on me... :cool:

I've found a set of Mustang Injectors on eBay, Bosch# 0280155710, pretty sure they're 21#, 4-pintle
will these fit a 1995 318iS???

Actually got the injectors off fairly easy. I had the lower intake off the head already so I didn't have so much leverage to pull them apart.

So, I shot both sides of the injectors with PB Blaster, let them set for 30 minutes, then used a pair of brake caliper compressors between the rail and the lower intake manifold to carefully push the rail off the first two injectors. Then used one of the brake caliper compressors to remove the third injector, then just twisted the fuel rail to remove the last one.

The original o-rings were very hard and using this method made it very easy to remove them without damaging the rail or my shoulder.

Putting many things back together today, I expect to have it all back together next weekend.

:cool:

With the injector secured on the rail with that clip, there is the 2,5-2,8mm between the plastic edge and the intake. The washer is not necessary because the injector sits nice and fine on the fuel rail and is also secured, but because I'm paranoid, I added the 2,5mm washer to eliminate the possibility for the injector to go too deep, just in that one in a million cases the clip fails.

The result is quite good, much more low end torque, different sound of the engine, more relaxed overall. Would recommend the upgrade.

I recently also installed these same injectors (cheap ebarf deal). I ended up losing the washers altogether since I expected annoying rattles and I just trust the circlips not to fail. So far they haven't. The increase in power and even more so in smoothness is remarkable. Best upgrade for the small budget imho.

Justin and I installed some 4 pntle injectors. there was benefits in MPG and throttle response

i�m thinking of doing this, but only if it doesn�t affect emissions. the car has to have it�s yearly TUV exam scam.
anyone do this in an area that has emissions testing?

papercutout · « **Reply #161 on:** July 29, 2009, 01:34:54 PM »

I doubt it spanish_pants, but it'll be a benefit if anything - more efficient fuel burn = less emissions.

All back together again. Seems peppier and way smooth. I'll see how it does over a week of daily driving vs. my thirsty 540it. :cool:

tjts1 · « **Reply #163 on:** August 06, 2009, 11:45:42 AM »

Nice work. Let us know how it does over the long term. Great pics too.

papercutout · « **Reply #164 on:** August 06, 2009, 02:14:18 PM »

Long term for me - definitely a little up on power and torque. Still definitely getting more MPG - ALWAYS over 300 miles to a tank, once as much as 350 combined motorway and to/from work! Done a few thousand miles on them now too.

Anyone else?
