t3/t4e 60-1 turbo... what injectors??

[snowmansdsm09]

So I just got my hands on a new t3/t4e 60-1 turbonetics turbo.
I need to know what injectors would be my best bet for this setup??

I just ordered a tubular manifold, external wastegate and 3'' downpipe for it...
I plan on putting in my VENOM Sheet Metal intake manifold the same day I do this swap.

I was thinkin along the lines of 720cc injectors???


Any suggestions would be nice... thanks




KEEP IN MIND, I've read this turbo produces 800cfm... but I have not confirmed that 100%

950's. Bigger is better and having low IDC's is better than maxing out smaller injectors and starving for fuel.

Buy once and do it right,

I use 70% of my 850's on a 3052 turbo, 255 Walbro and -6 feedlines at 25 psi. I would not go any smaller than that....there is no advantage to it.

Keep in mind the piggyback won't work alone. You will need either injector compensation via a chip or dsmlink.

Ain't that the truth!

 

[snowmansdsm09]

Ok wow, I wasn't expecting someone to say 900cc injectors.
I thought the max would be around 800cc or so...

DSM link has to be used??

I have SAFC and MAFT - could I just use both of use together?

Whats the max boost I could run on the 550cc until I got the Injectors and DSMlink????

 

[olmytsi]

Dsmlink isn't required. You can get a chip which still requires a 95 eprom but it's cheaper than dsmlink. With the chip, you keep your afc/maft to make the fine adjustments. With dsmlink, you sell the afc and can keep the maft but leave it set for stock injectors.

Here's why you dont want to use piggybacks. An afc or translator doesn't actually lean the car out. It just lies to the ecu by hiding airflow. So you flow 20 psi worth of air but the ecu sees very little air and thus gives you ALOT of timing. Too much timing on pump gas and you will knock, even on race gas. So imagine lying to the ecu for REALLY big injectors. You would get insane amounts of timing.

Dsmlink or a chip makes the correction at the ECU itself so you get the stock timing maps at wot and the car runs ALOT better. I have 660 cc injectors and I went from an afc to dsmlink and my car runs WAY better and not just at wot.

Good Info...

Eprom ECU's are going for a pretty penny right now though! :-(

Will the Chipped Eprom run just as well as the DSMlink??
I know I have to get the eprom no matter what...


How much boost can I run safely on the 550's?? 12-14psi??
(until I get bigger injectors and ecu chip/dsmlink)

 

[olmytsi]

The chipped ecu will work well if all you are looking for is injector compensation and a stutterbox along with the other little mods it gives you. Dsmlink is all that and offers alot more so it's really up to you. Keep in mind you can sell the afc before you get dsmlink since you can use the translator to keep the car from running pig rich 'til you get dsmlink.

Are you saying you have no logging capacity? Why did you waste your money on a tubular manifold when you need fuel mods? You're doing things ass backwards, I would hold off on intalling the turbo until you're ready.

 

[tstkl]

Hey, let him do things backwards if he wants to (thinks of himself with that damn smim). If your going to run 550's, log your idc's and once they hit around 75%, thats what boost you should use. (that way, when your in higher rpm ranges, you should see around 85%, and worst case senario you will see like 95%, then you can turn it down) have a friend ride with you watching your idcs and just test things out, starting at the lowest you can go. Feed your wastegate with a pre intercooler boost source, with the shortest vac lines possible, and no mbc to start things off. If your friend starts seeing too high idc's, well I guess your s.o.l.

Personally Im getting 1000cc injectors and a chip, seeing as Im tired of staring at 98% idc's shaking in my boots. If I get any knock as of right now, Im kinda screwed because I can't add any fuel. You can try turing up the base fuel pressure (with either an adjustable fpr, or crushing your stock fpr a little) then compinstating with the afc/maft, but the problem with that is it adds timing because its taking away airflow. I thought going from 37psi base fuel pressure to 46psi base fuel pressure would help, but the airflow I took out just caused my car to add timing, and it still knocks, unless I dump in 100+ octane gas. Do it right the first time and chip your ecu for huge injectors, or get dsmlink and get some huge injectors.

I have a logger, I just wanted an idea of max psi i could run so I could start off safe.
I'll get the injectors and I'll upgrade back to a 255 pump again.

I'm thinkin I might just go dsmlink when the time comes for all that....

I'm doing all this ass backwards because I wasn't expecting to put the turbo on until I had everything I needed, but its killin me sittin here on my table.
Trust me, I know I shouldn't put it on.... but temptation has gotten the best of me.

 

[snowmansdsm09]

How do you log IDC's on a 2g???

 

[olmytsi]

Dsmlink logs Injector Duty Cycle on 2gs. Not sure if any other loggers do it.

 

[snowmansdsm09]

So while I have 550's and Only a logger, what should I log to keep me safe while using the 60-1 ???

 

[andymoraitis]

Run low boost, and look for dips in timing that would indicate knock. If you had an EPROM ECU or Link, you could see knock directly and tune out of it.

Log your IPW and do the conversion here. http://web.archive.org/web/20050228072055/www.taboospeedshop.com/IPW2IDC.htm

I'm planning on using the FIC 1150's with my setup, but then again I'll be running a bosch 044 and few other things. I wish I could use the 1600's but those are like a shot in the dark in getting a set that will be streetable. I dont trailor my car to the strip. but if worse came to worse I'd use 8 injectors.

I fully support dsmlink, and cant wait for V3 to come out, it is worth way more than they charge for it. I'm about to purchase a 2nd dsmlink for my other awd. But yeah I agree with the guy above, if you dont have all the fuel requirements for the turbo, just tune it for your injectors and run low boost but honestly, at least get a set thats bigger than 850's before you start runnin around boost happy with this thing

 

[snowmansdsm09]

Ok I decided I will end up buying the 850's...

But I need to get the eprom and dsm link first i think so I can actually have something to tune with and not have timing issues.

Will this setup be streetable??

Currently this car is my daily driver, I also own a Z28 but its just not as fun to drive so it's about to be sold.

 

[olmytsi]

Yes it will be fine.

 

[snowmansdsm09]

alright guys, thanks for all the comments and suggestions.

I'm feeling alot more convident in what I'm about to do.

Thanks again

[snowmansdsm09]

ok guys... I'm startin to get nervous and question why I'm putting this on before I do the neccesary supporting upgrades.

Since I can't log IDC's... how do I log IPW's????
I checked my tuner'stein and I don't see that option...
ObdGauge doesn't have it either....

I need to know exactly what to watch so I can put maximum safe psi w/ my 550's for now.
Timing... ( I know )
Anything else????

 

[tstkl]

umm... if I was you I wouldn't be worried about running the most boost I could with that set up. Just keep it low and safe until you get dsmlink and those 850's or whatever. I would be really surprised if tunerstein couldn't log ipw, so just log everything and look for the one thats in the right units and if you still don't see it, seriously, leave the 60-1 out until you get dsmlink and larger injectors. I personally won't be changing my turbo until my car can support one twice as big (overkill... but thats just me)

if you can't find ipw, don't risk it, just sit on your hands and wait til you get dsmlink and larger injectors, I can't stress that enough.

Interesting....

Hey, let him do things backwards if he wants to

 

[snowmansdsm09]

Well i got everything installed 2 weeks ago, been tuning it.

Right now I'm hittin 16psi, 21 timing advance at 6700 and still gettin .97 volts on o2.
So it seems I'm still running rich...

The car is really scootin though, I love this turbo.


Should I turn the boost up another 1-2 psi or just lower my fuel some more????
