how much to retard timing

[rco8786]

Ok, at a maximum of 10psi, 7psi daily...can i get away w/ using the distributor to retard the timing? if not, what would be the easiest way to do it and how much should i do it. I don't have the funds for a new ignition and all that good stuff. I will be running a T3 w/ safc, walbro, stock injectors(for a lil while).

I would not boost on stock injectors!

[:: orion ::]

Stock injectors will be maxed at or before 4psi with only an AFC - It can add more fuel IF the injectors are not maxed, but once they are at 100% duty cycle, it can do no more...

Only way to make injectors flow more is fuel pressure...an RRFPR is a decent cheap choice, but I'd reccomend getting some 370s.

Those will get you to about 250rwhp, or ~9psi from a T3 (maybe 10psi for 250rwhp, but that may be pushing it).

im going to use stock injectors with walbro f/p and fmu. with a max boost of 6or 7psi. i think this should be ok. i also want to know about the timing. i was going to retard mine 1 deg. i want to know exactly how to adjust it to exactly 1 deg. with the distributer?

[WDRacing]

At 7 psi just retard the timing 1 degree. When money allows, purchase a boost dependant timing controller from MSD or similer. They're about $130 I think. I'd suggest a knock metter, but if you can't afford a timing box, you probably can't afford a knock metter.

If you use a FMU you may want to invest into a fire extinguisher! I say this because of how much fuel pressure the FMU builds in the fuel rail and lines.This will only cost about 40 bucks and I would have one because my car cost thousands and I really don’t think I could replace her.

[rco8786]

Ya the injectors are only a VERY temp thing...and really this whole set up is. 10 psi will be absolute max for a dyno run or something, so 370's should be fine for me. Thanks for your help guys.

just make sure that your ECU (or whatever else you might be running) knows how to pulse your injectors correctly. You cant just change injectors and not worry about how they're controlled when you decide to upgrade.

[daniel240]

yea thats one reason i want to keep the stock injectors

[I am Technoman]

Humm the greddy e manage cost less than 300 dollars on ebay and 370's should only be around 100 dollars max! Oh and a new fuel pump is around 100 dollars so for about 500 bucks I can have a pretty damn sweet fuel setup that will take me to around 300HP at the flywheel humm ill go that route!:D

the safc will handle that won't it?

yes

Does the e-manage allow timing adjustment?

[daniel240]

how do you adjust the e-manage for the injectors?

[I am Technoman]

Does the e-manage allow timing adjustment?

Yes, but you have to buy the timing harness and i think you can also buy a MAP sensor so the E manage can see boost but that will not allow you to remove the MAF. It just can see boost and move timing.

[I am Technoman]

how do you adjust the e-manage for the injectors?

In the program that you run on your'e laptop or computer you can type in 370,440,720 get the point? And you can also tell it that you have a Z32 MAF!

[I am Technoman]

With a properly tuned E manage and fuel pump and a set of 440's you should have no problem boosting 12 PSI or maybe 14with good gas!;)

[DriFt3r]

How reliable is the emanage and is it worth the money?

[DriFt3r]

Do you guys think that its better then the jwt ecu? I rather spend $500 on the emanage if its better then to get a jwt.

[I am Technoman]

I know a few guys who run the e manage a love it! It really is a good fuel ECU for the money. BUT if your plans are to run 400HP or higher go the JWT or a stand alone I only want maybe 270 RWHP out of my car so the e manage is my choice.

[DriFt3r]

So if I am planning on more then 400 hp then the emanage wouldnt cut it? So its better to get the JWT then?

The e-manage would technically work...but if you're spending that much $ on your motor anyway you're better off w/ the JWT.

are you saying you're gonna run 10psi on stock injectors? or 370's. Im confused

[huguetpj]

Why would he? With the e-manage he has tune-ability... and at 400HP I bet that comes in handy.

[rco8786]

No no no...I wouldn't touch 10 psi w/ stock injectors. They will be *hopefully* pushing 7 for about 2 months....but most likely I will end up just buying injectors b4 I turbo anyway.

Ya I guess that's true..

[I am Technoman]

I think a JWT ECU and a E manage piggy backing it, would be sweet! 7K rev limit no speed cut, base map is setup for turbo and you can tune the JWT ECU with the e manage on the dyno! This would cost about 1,200 for all the harnesses and stuff.

This is what you could do.Z32 MAF upgrade without sending it back to JWT.Upsize injectors up to 720's without sending it back to JWT.Control timing for more HPAdjust A/F mixtures for the most HP without sending it back to JWT.Use sub injectors and harness for alcohol injection "big boost"Use the data logger to analyze and record what the engine is doing.

I would also like to have a wideband o2 sensor.This setup would be good to well over 500HP!

[huguetpj]

But then why would I spend my money on the JWT ECU since I can do everything it does (except maybe for the rev limit) with the emanage?

[I am Technoman]

I would really like to go faster than 120MPH

WD do you have any links to those boost dependant timing controllers?? Thanx
