Well I swapped margaritas at the beach and (2) 78° F beach days for spending a total of 30 hours in my garage this weekend.
It always starts the same. I open the garage and am greeted by my current non-running car, that will hopefully running in a few months.
And then I look to the right and a see another non-running car that will hopefully be running before I'm dead.
And then I look down and see the mountain of stuff I need to sell or scrap.
Somewhere in here is a 2.2L short block I need to take apart
First thing I did was ship my intake runners to Ermish so he could port map them to the head he's building. The red marker shows places where I need to grind down flashing or casting that has made stud/ nut clearances a pain. The runner extensions are 40mm, they lead into 40mm throttle bodies, which lead into a 45mm intake runners, which reduce to 40mm where it meets the head. I'm not sure if the 40mm to 45mm jump creates a ton of turbulence, but I'm guessing it's not ideal.
I've been told that the throttle body size effectively determines where your peak torque is going to be (smaller=lower, bigger=higher). My previous EFI LZ engine gave me 138 ft lbs to the rear wheels at 4,500rpm. With the 4:11 it would pull stumps from 3,500- 5,500 rpm and it was done by about 6,000. The original design criteria was a quick stoplight-to-stoplight car, and on great occasion it served me well
In looking back, a set of 45mm's would have been optimal, it think 50's are too big for the street.
Does anyone know if I can get away with using these 40's on my SC engine? I'll have to research this one...
I'll try to smooth these out a bit when I get my die grinder. Looks like they were given a quick pass the first time around.
Taking everything apart was fairly straight forward. I hope to remember how it all goes back together.
I used my dremel on this job and it spit aluminum everywhere
. I need a grinding chamber of some kind. I was wearing a pretty decent dust mask but still...
Question: Are these injectors too high up in the throttle body? They seem short.
I then turned my attention towards the 2.2 block. It's an 06W.
This thread has come full circle: viewtopic.php?f=30&t=14219
I cleaned up the deck (it's flat/ no warpage) and a few pistons.
Can I use any of these parts in the LZ conversion?
I was very surprised to see the check-ball had blown out. Can these get stuck in the block? Am I screwed? I have a remote oil set up from my race car I can run for the time being if that will solve anything.
This was also a bad thing to find (coolant mixed with oil), including a random washer sitting in the bottom of the pan.
More on this is tomorrow, but I also pulled the driveshaft, transmission, steering box, alternator, starter, and marked up the header for O2 and EGT bung placement.
All in all a productive weekend.
