Which should i do. Its become obvious my 60lb injectors are to big for my 2.9. so im dropping to a 2.8 pulley. Is that enough to feed my 60lb injectors or do i need to just max out a set of 42.5lb injectors? No more mods after this. Getting ready for a final tune

Which ones with a 2.8 60lb or 42.5lb?

 

60's and new tune with the 2.8

 

seems like everyone whos blowing #4 piston is using 60lb injectors, no one running 42.5lb'ers has blown #4 yet, right? seems like our fuel rail isnt big enough to hold the amount of fuel those things need at high rpms, so im guessing, because in no way am i an expert or very knowledgable on this for that matter, but if those things guzzle gas at such a high rate theres not much left at the end for the 4th injector, hhhmmm, my 2.85 has been running fine on 42.5 for, a year.

 

The fuel rail thing is complete speculation. No one has tested it so don't think I fuel rail will solve any problems, unless you are willing to be a test case.

I have been using a 2.8 with 42.5 with nitrous for over a year no problems. I keep my AFR in the 12's and use modest timing.

 

i totally agree its complete speculation, could be the fuel pump, could be it gets to hot while trying to make that amount of boost through the blower, however i feel comfortable runnin my 2.85 with my 42.5 injectors and have no desire whatsoever to push my blower to the point i would need 60#'s, i think too many people are tryin to make too much power off this blower, i would much rather go with some cams and a port an polish and a good tune, i think everyone is totally overlooking the capabilities of the ecotec and concerning on more boost, theres much more power to be made through the engine alone, take for example the k motor out the rsx, i got a buddy with a civic who did a k motor swap, completely stock setup, made an extra 60hp just off camshafts, springs and a tune, imagine how much more efficient our blower would be if we could make an extra 60hp off the engine

 

water injection and 42's

 

go 2.85 and 42 .60 is more then our week ass fuel systeem can handle.

 

well, your at about 1200ft above sealevel there....
id say a 2.85 would be the safer option.....
if you do ALOT of WOT runs....id say even think about a 2.9
2.8 can be safe, if your at higher alt....or you tune it well for it.
but its also right on the edge of injector duty cycle.

if you really want to do 2.8 or lower....id go 60s for safety

 

I think the other thing People are missing is Better cooling, They throw lots of Boost at it & No upgraded Cooling for the Intake which in return Creates Heat! I've been running a 2.8 & 42lbers for a year No Problems!

 

yeah but not about what happens at higher levels and if people are willing to answer back wtf should you care?

 

rules say does add to the site and it does. The forum is for sharing info and the more info on a topic the better. Btw the search button is a pos you can search 2.8 pulley and 50 threads about different random **** . The criteria for the searth is if 2.8 is mention in that particular thread it will give you that. It can be frustrating searching throught that ****. And this site is basically 50/50 on wether the 2.8 2.85 or 2.9 is safe for the 42 injectors so what is a few more opionions?

and obviously hes not a idiot he has close to 2k posts so im sure he did a lil searching...

Anyway, to my understanding meth injection helps reduce injector duty cycle so i guess if you really wanted to run the 42's and a 2.8 meth would help you.

 

yes info on this

is this true

 

Part of the reason the search function is a POS is because people don't stay on the topic of the thread. If you search you can find info on this rather easily. But now we have another thread that will show up on this topic to search through.

 

um, no.
water injection alone does not reduce idc's.
however, timing can

is anyone running with a 2.8 pulley and 42.5 injectors? Any probs???(only helpful one 8 pages long though...)

This is what I got for searching the exact title of this thread so sometimes its just easier to make a new one

 

You can run more timing with meth, in turn reducing idc.

 

So look through the 8 pages and not put your laziness and convince over the rest of the community.

 

Speaking of staying on topic. Mods your interrupting this thread. Come on. Thanks for the input guys. I searched. but newer info is better.
