whats the biggest inj. I can get

littleredstroker · Nov 13, 2011

I have had some issues gong on and they have gotten worse. slight miss turned to major miss when cold turned to very hard start then to no start unless its plugged in. motors got 165k on stock inj and Im thinking (unless you guys have another idea) its time for the fuel shooters.

My question is this, with mods I have done what are the biggest Inj I could get without having to go with a different turbo. And which nozzles 100%-200% are better for what reasons.

I am gonna ditch the sinkership and get a TS 6pos and run single shots also.
Its a daily driver, tow rig up to 15k, and do some pulling at local fairs.
any advise/info will be appreciated.

238/80. Add a 38r and be done with it.

I'd go with a 238/100s and get it custom tuned accordingly. Gives you room to grow also.

Cold compression check might be in order....

thought of that.. Its hard to explain but once its running It misses, after warming up and a little driving its like one or 2 inj just POW miss goes away like the flp of a switch. and a very slight miss all the time.

IF it was cold compression wouldnt it gradually go away?

Just trying to save you some heartache when the injectors dont fix your problems.

Just check it.

I didnt mean to sould lke I was being closed minded. I want other ideas. How do you check cold compression? and how do you fix it?

Check your compression when the motor is cold, fix= refresh

No no...your fine. I just ask that others do a little diagnostic before blindly changing parts. Injectors are not a part to change...just cause....there expensive....and you need to be sure that is your problem first.

ok i get what a cold compression test is. what i mean is how do you do it. and if it was a compression issue what would be the way to fix it ? for 165k it seems like that would be early for a compression issue. it has never once smoked a lick of white which from what I read is related to compression. Injectors have been on the back burner for a while now and ive finally got the time and $ to do it so im gonna. thats why i wanted info.

Exactly, at $1800+ I'd make damn sure that was my problem first. I'd also check your uvch, make sure everythings plugged in.

why 80% now? :lookaround:

SouthFlstrokin' · Nov 13, 2011

If your not smoking white, you prob have another issue. I would look into your hpo system

littleredstroker · Nov 13, 2011

I have adreanaline with not even 10k miles I put a new ipr when I did hpop and icp about 3 monthsa ago. What else is there. 455cc...sounds good lol

do you run injector cleaner in your fuel???

My parents pickup had a bad miss and when cold if you reved it up to 1750 to 1800 rpms it would just stop right there and blow lots of bluewish white smoke. BUT once it wormed up it would all but go away.. So we started running some injector cleaner in the fuel AND it whent away completly col or warm it revs all the way up AND no longer smokes....

Could be just dirty injectors. not bad one just dirty..

A set of 160/80 injectors will bring your truck to life. They are relatively inexpensive and aren't 'too much' for still using the truck to work with

littleredstroker · Nov 13, 2011

I've used standedyne treatment but that's not really a cleaner as much as it is additive I think. What's the different nozzled do, what are they desined for. Besides emptying faster

:whs:

I was thinking more on the lines of a 200/30 just because they have the larger P&B's and it will let your adrenaline be more efficient in the time of need.

ullover:

If you really want to keep the stock turbo that is. Plus, if you do decide to keep the stock turbo plan on getting a ported compressor housing to take care of the surge.

Edit: But before you go dump money on upgrades make sure new injectors will fix the problem. It'll be a sh!tty day when you put them in and it's still happening.
