Re: LS turbo advice needed...
Also, alternator. If you are running a 4 prong alternator, get this.
https://sloppymechanics-com.myshopif...-combo-harness Plugs right into your alt, and right into your term x harness. DONE. No more alt. bull**** to worry about.

Re: LS turbo advice needed...
Does the Term X use the connector for the coil harnesses or does it have each individual coil connection? Thinking of relocating the coils off the valve covers and wondering how hard that might be to do as far as the wiring goes.

You can absolutely move the coils, you just will have to lengthen roughly 8 or 10 wires per side to wherever you are going. Im doing this now. Debating. I have the holley valve covers that cover the coils but i keep getting the wrong ones. First ones wouldnt plug in, 2nd ones are to tall for the cover to fit. Debated just moving them all together.

Re: LS turbo advice needed...
This is a fabulous thread, thank you guys for all the knowledge! I am just about to get started on my LQ4 turbo build.
Have any of you looked into or know anything about the kit CX Racing offers? https://www.cxracing.com/turbo-kit/t...10-6772-IC-RAD Also, lyrikz, what did you end up doing with your coil relocation? I would like to move mine as well. Hook it up with some pics if you got em! Last edited by dag19; 06-04-2020 at 08:26 PM. Reason: Updated CX Racing Link |

for a turbo app, if E85 is available in your area...I personally would run it. Plan your pump and injectors accordingly if you plan to use it

Re: LS turbo advice needed...
I would like to run E85 since I hear you get more out of it that way. The trick will be finding somewhere that sells it around here in western NE. Where at in the fuel system should I mount the sensor?
For injectors I intend to go with Deutschwerks EV6 95lb/hr injectors. I was looking at a Boyd's Welding tank with an Aeromotive Stealth 340 fuel pump. Would that system suffice? |

I'm on stock HG (not even MLS) and TTY bolts and I run 12-14PSI on the street, but I usually pull boost back to 10psi mid summer when it's 100 degrees in Central TX. I also have a wideband readout going 24/7. Seriously buy the Terminator X though. I'm on a megasquirt MS2 and I've been eyeing the X for a while now.

sorry didn't see this till now. If using a return style system the sensor you'd want on the return side...it's 3/8 line size. If you are running dead head setup you can run the supply fuel thru the sensor if needed...but if you are planning larger supply lines -8AN then the sensor would be a restriction. I'd skip anything Deutschwerks and look for a real Siemens or Bosch injector, 80#/hr that 340 pump sounds good...I've also used Walbro 450 with good success on E85

Re: LS turbo advice needed...
No worries, I appreciate the input at any time!
I do intend to run a return style system. I haven't decided on supply/return line sizes. I assume what size comes out of the tank will be my limiting factor and just stay with that size throughout the system. Good to know on the injectors. Is there a big price difference? Or its a moot point due to the quality of Siemens or Bosch? |

Re: LS turbo advice needed...
Siemens 80# are in the $400 range for set.
less than DW and higher quality (thank GM or Ford for footing the R&D)

Re: LS turbo advice needed...
Stupid question...or really a verification of what I think I've figured out...to use Siemens Deka injectors you'd need the mid length 48mm style for an early truck intake? Looks like the long version is if you are using a car style intake. And wouldn't it be better to go ahead and get the EV1 connectors? The Multecs don't seem very common. The Terminator offers several connector options. And where can you reliably get the genuine Siemens injectors to insure you don't get the fake knock offs? Still seems like the 60lbs would get me down the road fine, 80's would be a sure thing but there are all sorts of rumors out there about idle quality with 80's. Plus the Term X software only lists the 60 in the drop down menu. Any experience with the Deka 80 and the Terminator system? Thanks for all the great advice!

Re: LS turbo advice needed...
I'm using the 80# Deka 'long style' on a magnuson supercharged 6.0L
I felt the car idles just great, and low speed drives great. Sorry I do not have experience with TermX system...to know what it works with. The knock offs area real problem...I have set of 60# knock offs now in a car...and they have to be swapped. Can't get the AFR where we need it, they don't respond like they should. Idle sucks...no atomization. These were sold by "TRE" The Racers Edge. Total junk. this place sells real Siemens stuff: http://www.siemensdeka.com/product-c...uel-injectors/ depending on the year and type intake you are using, if you have an injector out of it just measure the length from o-ring to o-ring to determine if you need short, mid, long (37/48/60mm). otherwise mockup the rails and try to get a measurement. For connector style, this would be driven by your harness connector choice. if your harness has the USCAR connectors on it, get the EV6 connection type. USCAR type connectors are the ones with gray or green plastic CPA that you seat after they are mated. Earlier EV1 type use the metal wire clips in them, and the latching features are on the sides of the interface. There's likely more choices in the later USCAR type EV6 in my opinion

Check out SnakeEater injectors. I just ordered their set of LS3 style 1500’s. Owner is a standup guy and stands behind his product. They are super affordable and are flow matched to a 2% variance. Hell Holley just updated their software to include SEP’s flow data onto their system. |

Re: LS turbo advice needed...
I'd be vary wary of any of these aftermarket injectors, after what I am seeing with the TRE stuff. Yes your car will likely run if you get the flow rate close in the table, but not as well as it can. also if one sticks open, you quite possibly lose an engine (hydro lock).
I looked at the latest DW 95lb. and they do seem to be using a genuine Bosch injector EV14 series. so that product from DW should be decent

Re: LS turbo advice needed...
another question...at the time it seemed like a good idea to run the wastegate to it's own tiny muffler instead of looping it back into the main exhaust but I'm wondering if the injection system will or won't like this? Will it screw up the AFR readings or will it be ok?

Re: LS turbo advice needed...
Anyone have experience with Ballenger Motorsports? Looking at getting the Deka 80 injectors from them and they appear to be reputable.

Re: LS turbo advice needed...
Anyone want to share their real world experience with crankcase venting / pvc system with their ls turbo? I’ve searched and there sure are a ton of ways to do this. I’ve seen huge lines from each valve cover to a breather tank and the pvc deleted, I’ve seen some try to use the stock pvc system with a check valve and a catch can, or some use the Mighty Mouse can with pvc built in. But I’ve also heard of people blowing smoke or pushing out dipsticks, etc. Just want to know what you guys have run successfully on the street. Thanks…Mike

Prior to venting the otherside it would hiss on shut down so I knew I needed to vent it. No problems with this set up. Cost me $20-30 bucks.

Re: LS turbo advice needed...
A question for anyone familiar with the terminator x…the instructions say the fuel pressure sensor is optional. Is there any real advantage to running one?
