Alright, I just bought a brand spankin' new T04E. It is a 60-1 with an exhaust A/R of .84 and a compressor A/R of .60... I had originally wanted a 62-1, but this was a pretty decent deal...

Currently, I have just stock ports and a RB Turbo-back exhaust system...

Here's my questions, and there are many...

What size injectors will I need to run with this thing?
What's the maximum safe boost I can run?
Do I need to get a Haltech or some other standalone, or can I just get an S-AFC II?
I know it won't hook up to my exhaust and I will have to have that modified, as well as getting an aftermarket exhaust manifold, and I am going to get a nice, big FMIC. Now, what do I do about an AFM?
Last, what kind of HP do you think I will get out of this?


Oh yeah, forgot to mention: 87 TII.

 

If you're going to rebuild the engine soon, you could just run it with an S-AFC and some ghetto engineered tuning, then when it blows get a full standalone.

Matter of fact, just get the standalone.

 

Ok, so if I go with the stand alone, what do I do about an AFM?

 

Throw It In the garbage. You will not need It.

 

I thought you had to have some form of air sensor with fuel injection? What will take it's place? Silver, can you help me out with any of my other questions?

 

Do a search for speed density and the MAf EFI on google.com, you will find some info there that will answer your many question..Max

 

Your EMS will use a Manifold Pressure Sensor and possibly the TPS (depending on the EMS) to determine your engine LOAD (how much vacuum/boost).

It also uses Water Temp, Intake Temp sensors etc. to determine how much enrichment is required for cold start etc...

 

Ahh, cool. So, will I be able to throw out the stock computer then?

 

yes, thus the term "standalone" it stands alone

 

doesn't the stock ecu do like power windows or locks or something too though?

 

is that why my REAR windows haven't worked since I got a PowerFC...

 

Alright, so I will order a Haltech...
I am going to get 550 cc primaries and 1600 cc secondaries... That's what 1fastT2 runs with his T04B... He says it's overkill, but I figure I would rather have the extra capability than not enough. I already ordered a Walbro 255 lph fuel pump, and I am hunting for an FMIC right now. Any other suggestions?
By the way, no one answered me before... What kind of HP do you guys think I can put out with this? Also, what's the maximum safe boost I can run on 93 octane?

 

With some good tuning and about 15psi I would think somewhere around 370rwhp.

 

Yes, You will need a piggy back for your stand alone for the power windows and locks to work.

 

i have an xs to4e kit. the norm is about 15 psi. . . but it can produce higher numbers. ill be running 20 something psi when i wanna race the big dogs. haha. thats with race fuel btw. anyways, on 93. . . id run 15 psi. good all around street setup.

That is complete BS........ after removing the stock ecu and running stand alone.. every thing will still work like a normal car as long as you pay carefull attention to what wires / harnesses you remove. EVERY THING can work from your lights, guages, windows, wipers etc. Each have different harnesses from the main engine ecu. Its a lot of work to do it right, but possible.

I second that.

My ECU is gone...everything works

 

Um, Yeah, that was a joke.
Although, I'm not too sure what you mean about the different harnesses from the ECU. The Only thing I had To rewire where the wipers when I installed my E6k. All the guages are hard wired to the sensors.

Glad it was a joke and not missinformation, but i didn't know it was a joke and maybe the noob to stand alone didnt know it either. Correct, the main ecu harness on the pass side will need to be split for the wipers and there was something else there also, i cant remember. Also if you want a tach, that gets rewired also, and your water temp will need to be wired into a temp sensor also because the ems will be using the water sensor now. I drilled and taped a series 4 water neck and placed a temp sensor there for the stock guage and used the one on back of the pump for ems (engine management system). The stock temp guage is strictly for refferense, if i need to know actual temp i look at my ems display hand unit (Wolf 3d).
