Hm, while I also dislike the idea of the FAST spacers going on the bottom of the injector, it doesn't seem like many people had problems using them, and I figure I'm just using stock injectors and not expecting to make any sort of big power.

I'm curious to know what you're saying about them not fitting though. They looked to be the exact right height to me.

The link I posted a couple posts above. The reasons the fast ones suck is because they can potentially alter fuel spray pattern And spaces the nozzle farther away from the intake valve. Those parameters are calculated for in the pcm. Long story short just buy the spacers that go on top

Btw the oil bypass can be ordered at improved racing.com

I dont like NOT having the keepers on the injectors. I made my own adaptors to incororate the keepers.
The reason FAST designed there adaptors to be under the injector is for satefty and liability. there is a vacuume on the underside of the injector and 60psi of pressure on top of the injector. FAST did not want the blame for a leaky injector adaptor spraying fuel over the top of the engine.

I'm not talking about the fuel injector spacers.

You cannot use a non DOD valley tray with DOD lifters.
Search... Search....Search....

Just a friendly hint. I learned the hard way

I am about to do the ls6 intake swap already the intake and tb adp and injectors can i use the fuel rail in the link above?

So I started to tear the car apart yesterday figuring I had 4 day weekend and word be a good time to do the swap. Well I gathered the parts and started into it. Then realized I didn't grab my OPSU. Which lead to search and turned up nothing. I have no idea where its at, so I need one. If anyone has a spare let me know.

Edit: I meant DOD sensor, nor OPSU

Finally getting the VLOM all welded up and remount mount OPSU for the LS2 intake swap if all goes well this weeknend i should have it all together and tuned.

This was a expensive venture because the first time i got it welded up at the shop the OPSU bung wouldnt clear the LS2's gigantic neck so i had to follow fieroguru's way of things and and cut out the OPSU out the top alltogether and remount it where the oil cooler block off plate is..and then take the VLOM to get rewelded...smh however if you plan on doing a ls2 swap You will need to do something similar, just dont make the same mistake with valley tray (vlom) that i did all the grinding and reworking myself everything inside that oil passage has been smoothed out and worked over for maximum efficency.

here was the first valley tray



reworked it to this









grinded the in the neck to far in and had to patch it. damnit...

pics of the plate that will be replaced for the OPSU relocation






all done







And just in case y'all needed sizes

Adapter for oil pressure..I had to thread I to 1\4 npt and then use a 1/4 npt to 3/4 npt adapter I found at Lowes in the air compressor fitting section

The Allen head set screw came from ace and is 3/4 by 10 , which is what I used to plug up the dod sensor hole

In case you need to know how I reworked the oil passage I did so with a angle grinder , a 1/2 inch drill bit and a dremel with a metal brush and beveling tool.

LS4 swap

iTrader: (1)

I swapped an LS4 into my 88 Fiero GT along with the entire drive train and electronics. My contribution to this thread is the LS6 manifold I swapped onto the LS4. You can do this swap with the LS4 components on it. I have seen lots of ways to do this swap but none of them used ALL of the stock LS4 components. So I tried to use as much of the LS4 as possible. WELL, the truth is that I only got the LS6 manifold and did not wont to spend the money on a bunch of other stuff, so I used what I had.
I used the stock LS4 TB, fuel injectors and fuel rail along with ALL LS4 components.
I made all of the swap components myself and it looks basically stock.
I will remake a set of fuel injector spacers because I think these are a little to high.
The LS6 manifold works VERY well with all of the LS4 stuff on it. I had it Dyno tuned with a "cold air intake" and free flowing exhaust system.

Can I put all the truck pulleys & stuff on the ls4?

so i bought another valley tray just for the sensor and soon found a problem. not all trays and not all sensors are the same. I somehow lost my old sensor so i needed a new one to modify. I didnt know the DOD trays came different so I just bought one on ebay. Well here is what I ended up finding.

old tray on top & right, new on bottom & left





Old sensor type is a straight pin configuration



New pin type is half moon



old solenoids are non-removable



new ones are removable




So I guess my question is which one of these would be the correct one for a 06 LS4? I know this got changed in 05 and 06 from 07 and newer on most LS applications. Im hoping just the new one will work and all I need to do is modify the temp sensor area like I had the other one done and Ill be good to go. Anyone shed some light on this?

Dom87SS

iTrader: (3)

ok that answers that. I'm bit unsure about the sensor thing and how you blocked it off. I was under the impression you need to leave it hooked up or it would run in limp mode. Im a bit lost as to what you did with yours, unless its just tuned out.

secondly, do you think I could remove the board that plugs into each solenoid and just swap it out that really would make my life a whole lot easier?

91parkave

iTrader: (4)

Taking off the gasket underneath IMO is a neccesary evil, In order to chop the OPSU and reweld at the angle you need to clear the intake neck. The heat from rewelding and debris will get everywhere and possibly destroy the gasket as well, not something id be willing to do for the little work involved. You could use the older one you have as well, since i t has screws and is easily taken apart.

Yes my DOD is tuned out so theres no need for the connector to be in place

Dom87SS

iTrader: (3)

my tray is already modified for the OPSU. I you look at my first pic you can see its now on an angle pointing out instead of up. The intake neck clears it after a little clearancing I did last year. The DOD solenoid sensor is my worry that it wont fit under the intake so it needs to be modified. What I was wondering is if the long black strip that plug into each solenoid is separatly removable so I could swap my straight sensor board off my G8 tray with the half moon sensor board I just bought. Sorry if this is confusing.

91parkave

iTrader: (4)

i couldnt answer that as i never had reason to take that off when i had mine apart, and its installed on the car now, i know with the old ones you can but not sure about the G8 one, im sure theres a simple solution though.

Dom87SS

iTrader: (3)

So the board on the solenoids is not removable. So its down to 2 options for me.

1) get a G8 DOD sensor and modify it to use with the already modified tray.

2) modify the new tray and the new sensor.

Ideally I'd like to do #1 but will do #2 if I have to

damn confusing ls4 engines and all the changing between years and vehicles.... im really wanting to do a ls6 intake swap on my 09 impala ss

Dom87SS

iTrader: (3)

well a real attempt was made at getting this finally done to my car...and hit another road block.

I didnt have the connector modified but wanted to see just how much clearance I needed to make for it. Plus I wanted to get framiliar with the removal /replacement of the intake and VLOM which I now see is a breeze.

heres the modified VLOM installed

[IMG][/IMG]

LS1 intake fitted on with the connector removed. It was good to see my TB adapter will work. I think im going to make a heat shield to hang off the bottom side and block some of the rising heat from the crossover.

[IMG][/IMG]



So I put the LS4 intake back on till I could get the connector modified but figured Id be a head a few minutes by leaving the modified VLOM in, which would be the case if there wasnt a problem. But once I fired the car it stared leaking oil immediately around the bolt head next to the OPSU at a steady pace. So I pulled it all back apart and put the original one back in and then found the issue. One the inside of the hold the bolt passes through in the VLOM there was a hairline crack that the pressure from the OPSU area was forcing the oil up through. The upside is I have 2 other VLOM's i recently bought just for the DOD sensor on them so I took one all apart and am going to clean it and have that one modified and I'm having a buddy who does race car wiring do my sensor up. So hopefully in the next few weeks Ill be able to slap it all together and finally be on my way to having something accomplished.

Will an ls2 throttle body bolt onto an ls6 intake manifold? I currently have an ls1 manifold with an adapter for an ls2 TB and just got myself an ls6 manifold for 150 bucks. So im going to be using the ls6 manifold instead of the 1.
