Blunttech e12 LSx / t56 swap

[jakeb]

Started on putting the engine harness back together.

Lay it back on the engine and start plugging wires in.



Pull them together and tape every time a wire goes in or out of the loom.


Just keep going along


That's a lot of wires....


Looking better....

steve, where is all that money coming from? dope project i didn't know about it!

I got an advance on my allowance. But for the quailty and work involved Jake is very reasonable.

It's got to be from the countless satisfied cocks, i mean customers.

Hey you!!!!!!!!!!!!!!!!1

Nice work as always Jake getting close

Plugging away...

O2 bungs fully welded and the remainder of the exhaust is painted with high temp paint.



Throttle cable bracket


Where it connects to the e12 lever. The throttle lever on the e12 normally is much lower and pointing down. It actually pushes when you push down on the pedal and uses a bunch of linkages up to the throttle body. For it to work with a cable it needed to pull... I was able to rotate it so the arm was pointing up and make it into a puller.



Then it loops around the intake.


Where it hooks to the throttle body


The coil for cylinder #7 had to be moved a little bit


GTO engine covers...they will need a little trimming on the drivers side to fit but they should work nicely

Should be this coming week.

Looking great Jake When do you think youll fire it?

Saturday lunchtime update.

Hard to really get pictures of this..but it all the high pressure lines from the power steering pump to the steering rack and the hydroboost. The T you see here is the return from the steering box and then from the hydroboost.



Lines coming off steering box


Connection at the pump


Oxygen sensor bungs tacked in...just need to fully weld
Drivers side..


Passenger side...added an extra here in case I want to log some data with my wideband and HP tuners.


Shifter coming up through...using the stock camaro stuff for now.

[ACHTUNG]

The spline count would matter for the clutch.... No spines in the end of the engine. Unless i am understanding you wrong. You want a t56 made for an ls1 and not the lt1 tho. Also make sure your lq4 is not an early one as they cannot be used with a t56. There is a removable spacer at the back of the crank. The early lq4 had a longer crank. I think 00-01 was the switch over.
Don't get a 99 or early 00.

No, I was confused. It is the clutch that receives the trans shaft. I get it now. I actually have a 2005 LQ9.

Nice comparison. I decided to go with the LS3 intake manifold with the 90mm cable TB only because I decided to run L92 heads.

On a totally different topic: do you know the LQ4's crankshaft input spline count? I'm sourcing a T-56 but not sure what spline count is needed for them to mate (the engine is at my friend's shop so I don't have access to it tonight).

[jakeb]

Small update...
Here is the difference between an LS1 intake and LS6 intake. The LS6 is on the left. They look the same on the top but on bottom the LS6 is flat...it is bigger on the inside and good for 15-20hp on it's own.



On the engine


Power steering/hydroboost lines are made


Other things done or at least figured out but no pictures of...
throttle cable
power steering/hydroboost return lines (they have to T into each other)
Drivers side exhaust manifold bolted on for the last time (I love putting things on for the last time)

The tach works off of an output from the GM PCM and hooks up to the tach just like the m30 did. There is some reprogramming needed on the PCM side but it is easy to do in HP Tuners.

For the coolant gauge I use the m30 coolant sensor and re thread it from m14 down to m12 in a lathe and put it in the plugged port in the passenger side head coolant passage. GM drivers and passenger side heads are both the same....just flipped from side to side.

The speedo is covered above...

The oil pressure gauge uses a s10 pressure switch in the stock GM location with a m16 to NPT adapter I get from summitracing.

I will also add a CEL light in the cluster as the e12 did not have one. There are a couple open spots to add a light.

I think that covers it. Let me know if you have more questions. Feel free to post, PM, or email me jake@classicdaily.net

thanks
