yes, are you looking for L67 injectors?

**suitercrew** · 01-20-2016

Yup

What are you willing to pay? I have a set of flow matched L67 injectors from zzp that have like 5,000 miles on them I might upgrade to 42lb.

**suitercrew** · 01-20-2016

Well i have no idea what a good price is or what flowmatched even means

Well I paid 150 plus shipping flow matched means they put them on a machine and basically pick out sets of 6 that flow the same so each cylinder is getting the exact same about of fuel.

**suitercrew** · 01-20-2016

Hmm well dang id hate to pay more for injectors then i did for my whole m90 haha. Ill probably pass unless you start feeling pretty generous!

Haha okay.

**suitercrew** · 01-21-2016

So when i redo my heads i was thinking of putting in stiffer springs because ill probably pick up some 1.9 rockers later down the road. I dont know much about valve train though so would there be any downside or upside to installing stiffer springs on stock rockers could i tune my shift points higher or something??

Also do i need an l67 map sensor or how does that work?

you need an L67 map sensor and a wire harness conversion to be able to plug it in. I have an extra map sensor that I would let go for 20 bucks, and you can have the bracket that bolts it to the supercharger, but shipping is going to be more because the bracket is bigger than it needs to be. Map stands for manifold absolute pressure. the way a supercharger or turbo works is that it increases the pressure in the manifold, so the atmosphere gets sucked in more to fill the void created by the increased pressure, and a 1 bar map sensor doesn't have the capacity to measure the increased manifold pressure, while an L67 does because it is 2 bars. you can get the wire harness conversion from caspers electronics, and maybe someone can chime in if you can just find someone doing a partout and have the map sensor wire harness cut off and spliced/soldered in on your car.

you should be fine running a heavier valve spring on stock rockers, but I'm not sure I would mess with the shift points until you actually do the rockers. some people suggest the 90lb valve springs, while others suggest 105 lb.

Don't you just fill it up until it starts coming out?

zzp sells the small 4 ounce bottles, so you end up needing 2

Ya i was reading all the top swap forum and i didnt see any mention of needing a map sensor but i was looking at the vaccum diagram for the sc and was trying to figure out how that would work. I thought the map was clipped on to the fuel rail? I also have the sc bypass actuatorbut not the bypass solenoid, but i heard you dont need one if you just run a vac line to somewhere there sees only vaccum. Is there any other parts im forgetting?

map and its pig tail is what you need. cut and splice the plug in place of yours.

**suitercrew** · 01-21-2016

How far down should i cut the wire since it moves locations do i need an extra foot of wire or just a couple inches?

**Scottydoggs** · 01-21-2016

id take as much of the donor pig tail as you can. where you mount it really dont matter, as long as its plugged in and has a vac line to it it works. but you dont want to see it on the front of the engine if you dont have too.

**suitercrew** · 01-21-2016

Ooo ok that makses sense now. My lim i got yesterday didnt come with the bolts but i heard my l36 bolts are the same and i can use those is that true?

**SgtMarshal** · 01-21-2016

a foot is plenty, better to have more than less. you can always trim it again if you want. it doesn't really matter how you have your vacuum lines set up as long as everything gets plugged in.

lim bolts should be the same, probably would be a good idea to clean the threads so they go in easier and don't lose their torque.
