just ordered a weber 34/34 DGEC

[2kredz3]

I got the cable to work and open the carb 100% I had to loosen the bump stop on the pedal itself. It feels good and strong but i am still loosing spark above 4k, i suspect its an issue with one of the coils. is there a conversion kit to make it use just 1 bank of plugs, or maybe to make both plugs fire at the same time?

[2kredz3]

Nice, i blew a head gasket today. turns out i wasnt loosing spark, rather loosing compression. front two cyl are 185, 182 psi rear two cyl are 82, 82 psi. sigh

checked the valves and all appears to be good, no damage to them. used a little video camera thing to see inside the cylinders and it looks like the head gasket blew between the 3 and 4 cyl (hence why they have the same compression)

I think it was caused by the removal of the vacuum boost valve which relieves vacuum pressure on decel. since i removed that when i installed the carb it makes sense.

anyway, i am going to start another thread for the head gasket rebuild.

sorry bout the head gasket man...

as far as the plugs go... you can just run your intake side and get rid of all the exhaust side stuff... just plug up the holes and all... no conversion needed

i personally run the pulstar pulse plugs.... they are sex!

[2kredz3]

Whats sex about the plugs? i have some fairly new bosch single plantum plugs in it now.

[PEZi]

the spark is 1,000,000 watts!!!!

[2kredz3]

lol, what is a stock plug?

[PEZi]

a base cheap pos plug (like the ones auto parts places have deals on all the time) are 50 watts

holy crap, thats $100 for a set of plugs. ($200 if you replace all 8)

could you tell that much difference? seriously

[PEZi]

i noticed a huge difference... but then again i was running old BS plugs before so i dunno if they'll make a big difference over a good plug... i got them for free so didn't care

basically to answer your question... when your current plugs go bad replace all 4 intake ones with the pulstar plugs... and the exhaust (if you keep the exhaust plugs) with just a good plug like the bosch

[2kredz3]

interesting

do you have any engine bay pics to show off? curious what others have going on under the hood.

[PEZi]

stay on for 10 mins... i'll go snap some, load and post

[2kredz3]

aight, im on all day so its all good

I work for a BMW speed shop running the front counter so needless to say i am bored sometimes.

[PEZi]

here ya go

[PEZi]

i'm in the process of deleting and re-routing wires and hoses to make it look better... but she runs great!

[2kredz3]

nice, your truck was white from the factory too eh. . . lol.

okay, well i am going to go put the new slave cyl on the truck while i have lift time.

[2kredz3]

i'm in the process of deleting and re-routing wires and hoses to make it look better... but she runs great!

I am doing that as well, you can see how much i have taken off in the pics. . .be carfy with the vacuum s*** (as i just found out) there are a few things that the truck needs to make sure it doesnt blow a head gasket.

[PEZi]

yep white it was!

i just need to move some of those wires and hoses around... i want a cleaner looking bay!!!

then i need to actually clean it too lol

[PEZi]

i'll be getting rid of the washer fluid reservoir soon... i'll leave the wipers until i have another car tho

[2kredz3]

mine didnt work when i got the truck so i removed the resevor (full of muddy water looking stuff from the 80's

[PEZi]

mine works just fine... but i don't really need it anymore since this is no longer a legit daily driver

[2kredz3]

yeah i get gas literally every other day so i just wash the windshield when i fill it up iv put 30k mi on it in a year

[PEZi]

mmmm... gas!

i love the smell of mine! the slight smell of amsoil and e85 mixed with the shell v-power....

[2kredz3]

your running e85 in your truck

thought this was interesting on the Z3 boards

Quote »I'm with you on this.. it decreases our mpg while destroying fuel system components.

Typically a gasoline delivery system will use Nitrile rubber for seals and hosing. However, Nitrile is completely incompatible with ethanol. So, despite what anyone might say to you, trust me on this as I am the expert, ethanol in your gas will deteriorate your Nitrile rubber components. Period. The recommended rubber material for use in ethanol delivery systems is ethylene propylene, and of course, ethylene propylene is completely incompatible with gasoline. So it boils down to this. There are two readily available inexpensive rubber compounds that can handle either gasoline or ethanol, however, neither of these two compounds can handle both, in any amount. There are options though. There are two materials known as "Hifluor" and "Perfluorinated" rubber. Either of these materials can handle both ethanol and gasoline. So why don't auto mfg's use them? The problem is two-fold but I bet the first thing that comes to mind is this.. Hifluor is roughly 25 times the cost of Nitrile and Perfluorinated is roughly 300 times the cost - essentially, the hoses would end up costing far more than, say, the engine block itself.. The second problem is that neither material has any abrasion resistance so using them in a dynamic application like, as a shaft seal for a fuel pump, is completely out of the question.. So, what's a manufacturer to do? Keep using the Nitrile and instead of them footing the bill for a some crazy expensive rubber components in the fuel system, they'll stick you with the repair bill every so often. Besides, that option only puts more money into their pockets..[/quote]

i run a blend of it... enough to get it up to 93 octane (we only get 91 here)

i've been very careful to make sure i don't put too much in and destroy the components... and i've kept an eye on them as well

[PEZi]

and as far as e85 goes... its awesome!

i know many people that did full e85 conversions and make assloads more power... depending on the make of the vehicle you need to do certain things tho... for subies all you need is bigger injectors a fuel pump and a tune... you can get an alcohol friendly one or a regular one that you replace once a year

on the downside... BMW's + e85 = fail

those cars really don't like running on them... methanol is do-able... but not ethanol

yeah dude, BMW's that get their tank on e85 come in with stripped fuel pumps and failed injectors. had a brand new 335i in here the other day with 3k in damage from e85. sigh

[PEZi]

yeah... aftermarket everything is the only way to go for BMW's... and the computer i've heard is still hard enough to program for it that its not worth it anyway

there's a few 240 guys in CO i've talked to about it... with easy programmable cars you just throw in the bigger alcohol friendly parts and tune... few of them have been running it for over 2 years with zero issues whatsoever

[2kredz3]

lol, you should hear my truck now. when its idling it sounds like a big block chevy with a came loping at 500 rpms. im only running off 2 cyl lol, great i have a 30 mi trek home in 45 min.
