hi there, i know this should be in the stoker tech but i cant post there or anywhere else for that matter. anyways im just looking for some opinions and possable problems i might run into with my current setup as im getting it back soon.

for the most part the car is stock exept the following

2.3 stroker kit, eagle/wiseco
stage 3 shep racing tranny
fp3x cams with titanium springs and 1mm over valves, (no porting)
spec 3 clutch
fluidyne radiator
air cond, and abs elimination

as well as a few of the cheaper things to do such as the 2g exhaust mani and caliper swap and egr, and free mods.

just looking for some opinions on what i should look out for so i might be able to prevent it before the car leaves the garage. thanks for the time and effort
 
be prepaired for torque LOL

The only confliction of interest I see is the injectors and means of fuel tuneing... I have 780's and before I got my Eprom/chip my timing was through the roof and it knocked like mad .... even at VERY low boost (8psi). Meth helped ALOT.... but the best I could do with an safc was 8-11 counts.... and that is way beyond unacceptable at that boost level. :notgood:
 
I run a manley/wiseco/4g64 crank stroker with a shep stg 4 trans. I would STRONGLY advise DSMlink as well as at LEAST 1000cc injectors + pump + AFPR. That, fuel wise, should be enough to get you into the 10's without much effort, provided enough airflow and a decent driver/tuner.

.....and a turbo to match ;) I don't see one listed in the profile so I'm still going to assume it's 14b powered.

Stroker motors like big turbos. I noticed a HUGE difference in spool time when I built my 2.3L
 
i do have 750 injectors (1000cc seems overkill for my application) as well as an afc neo, i didnt wanna go dsm link because im planning on getting the aem ems system sometime soon. as well i dont plan on running any more than 8 pounds of boost (probably 5) for a while untill i get a FMIC so i didnt think knock should be to much of a problem.

as for the turbo is it going to be 14b power'd for a while i cant afford a turbo at the moment but i have researched the turbo options for the strokers and decided to go with a dual ball bearing 50 trim, the aim being quick spool while holding around 22 psi.

unfortunatly other that the fuel system (pump, injectors, afpr, and afc-neo) the car is mostly stock so hopefully with a little luck it will run decent enough to break it in, and by then enough money to get the rest of the stuff needed to make a beasty. i know it sounds odd to do all this without even an exhaust but i bought the car used and it hatched the engin like a month later so i got a bit spend crazy while the motor is out of the car.

thanks for the info and reply's

Tisk, Tisk, Tisk.....:toobad:

I see some issues here...
First off. (( The reason why I cant stop saying enough how safc isnt worth it for this level of mods... )
The problem with safc is when you compensate for bigger injectors past like 680s you run into timing issues because by tricking the ecu in thinking there is less air flow etc. you are increasing timing. Therefore you will knock easy even on low boost as the other guy was mentioning. This is why I dont care much for piggyback...
I suggest you get dsmlink hands down, but the aem one will work too and if it turns out you cant afford that like most of us, then get the keydiver chip like I did which is much simpler...www.dsmchips.com
I cant even count how many times Ive referred someone to get this damn chip.
Well it basically gives you awsome inj compensation to make any injector work like stock, and same thing goes with timing adjustment, airfuel ratio, and mass compensation and etc.
Also ive read that strokers generally need a little less ignition timing.
In addition you will DEFINITLY, need a fmic soon because heres another issue...
Your on a stock 14b, in which first of all the stroker will suck that turbo out of breath in no time... The stroker motor set up properly with cams and etc can make a e316g feel like a t25 on a modded 2g if you know what I mean... *( wont be able to hold bost for long.)
And to get to what i was saying, if you arent running exhaust or open dp or something ( I think thats what you said ) it will cause a shit load of boost creep unless you have ext w.g. or a verry good porting job done on your 02housing... There fore boost creep + High timing + no fmic + stroker causing the turbo to work harder to hold boost ( therefore hotter charge ) = a crap load of knock and a blown engine....
And to conclude hope you break your engine in with some good pulls to help seal those rings quickly (I broke mines in on open dp by the way with hard runs and perfect compression now.)http://images.google.com/imgres?img...totune+engine+break+in+secrets&svnum=10&hl=en
 
Wait I just noticed that when you said you dont have exhaust, you ment it just wasnt modified, i was thinking you ment you dont have a exhaust system on the car at all thats why I was talking about boost creepLOL. But i wont edit my post above because someone else could still use the info I suppose.
Well then your boost shouldnt creep like I was talking about, and try to keep the boost low because im sure your timing has to be way jacked up ( especially considering 1g maps are already very aggressive.)... Personally Id put the 450s back in until you get something to control the 750s properly.. With the fp mod you have and the stock gst injectors youd be good to run up to 15lbs on the 14b safely, and then you wont have to worry about engine damage.
 
i looked at those chips and ill probably get the stage 3 chip if that will help out as it seems to be the only major issue at the moment, thanks for the info it helps alot
 
Get the chip hands down.

I can vouch for the E316g spooling as quick as a modded stock turbo 2g..... as I have owned both.

I've logged as much as 43 counts of knock at 5 psi at 1/2 throttle without a chip and with my cam angle senser set to minimal timing. :notgood: My turbo is larger then yours and is going to give a MUCH cooler air charge (especually seeing as I have "the brick" (MKIV supra) for an intercooler)

You are not going to be able to control knock. I ran meth after looking at my logs and I still got about 3-5 counts at 75% throttle at 10psi before I got an eprom and had it chipped.

After the chip....

0 counts. No tuneing, and I'm not even running the meth currently. ;)

If only we can convince the rest of the safc world how much better the chip is and what unnessecary loops there going thru for no reason LOL...:thumb:

With this ( depending on how far you want to go ) you may not even look at aem ems nor dsmlink again because this will be the simplest, and by far cheapest thing you could do for a optimal tune without any adjustments and no headache...
So did you put your stock injectors back in yet... Im telling you, you dont want to drive that thing with those 750s. Take 96gsdsm's advice and mines.
Besides you said you were breaking in your motor right, well like the motoman tech said you dont want to break it in lightly, and you will have to with them 750s. A bunch of knock counts plus engine break in doesnt work out well.
 
Not to hijack this thread, but say if he did get 780cc injectors and the chip to compensate. Could he still use his safc to fine tune with?
 
Ok cool, thanks. I was wondering because i may be going in this direction soon ( AFC/Chip combo ).

With the chip it's like tuneing a bone stock, already factory well tuned car. Just a little tweaking here and there... add some boost. etc.

I've known people who have sold off their SAFC's and loggers after getting chipped because they felt that they didn't need to further the chips tune. (however you can always take a tune farther, they're just lazy) :rocks:

AMEN put the 450's back in untill yeu get it chipped. Turn the boost down. (or do what I did and completely remove the wastegate actuator. It still will be a little faster then a stock Honduh with no boost. :D

Get your 20 rough miles in to seat the rings... andthe other gentle 480 to let everything elce mesh toghether, Give her an oil change, pop those injectors and your newly chipped ecu in and crank the boost till it knocks. :thumb:
 
well i havent gotten the car back yet, i had my chop order the srping and cams almost 2 weeks ago, i thought they would be putting it back together already but i guess there still waiting on the cams for another 2 weeks or so, i am going to get it chipped with the stage 3/afc-neo combo while im waiting so everything should be fairly smoth right off the bat ... hopefuly

if for some reason i dont get it chipped by the time the cams come ill throw the stock injectors back in untill i get it as well i do plan on trying that motoman break in

thanks for the info and with a little luck i should have this thing running strong before to long, as well i think i need to get some arp head studs....
 
i currently have a stage v engine block wiseco .20 9:1 pistons and eagle rods. with those setups work with 2.3 stroker? and is it still the same as to the limit of boost using 9:1 with 2.3 stroker?
