This may be a dumb question but all the numbers are for before TDC, correct? How much are you asking for your msd setup?

Thank you for the response. My 280z is an absolute dog. I can't keep up with a Geo Metro if I tried! How did your car drive with that setup? Did you have any issues with detonation?Also, did you leave your vacuum advance hooked up or did you plug the ports?

Hello. I have a N42 block with a P79 head which apparently lowers my compression to 7.8:1 according to http://datsunzgarage.com/heads/ . Through my research I've found many people who did this conversion tend to lock the vacuum advance and set timing to 22-26 degrees advanced. I've also seen one or two people set theirs at 15-17. They all pretty much have stock turbos and front mounts. My question is where are they coming up with these numbers? I've just read a topic on here about detonation where Tony D and Gollum I believe but up some interesting information. With that being said I want to avoid detonation as much as possible. Currently I'm using the stock n/a efi with fmu, wideband and front mount. Megasquirt will eventually be had once I get more comfortable with the installation and tuning process. Thanks, Matt

How is the setup holding out? Do you have any more pictures?

Thanks guys!! I'm not sure what I'm going to do yet. I just bought a washer dryer set because my wife demanded it lol. That money was supposed to go to my coilovers and wheels but she put a big X on that.

Here's my baby with a broken leg lol.

Lol. Thanks guys for the help. Since we are the topic of red neck engineering I made a bandaid until I can get new tubes. I welded 4 small tack welds evenly spaced around the tube. Then I went to home depot and bought a 2 inch high density rubber plumbing cap. I drilled a hole through the center for the strut and t clamped the cap making sure the clamp was under the 4 welds. I took it on the worst road I know and hit some good size bumps. Got it home and jacked up the front and it didn't budge. It's memorial day weekend so I gotta have to roll up to barbeques lol.

This is one side. The other side is much worse. It's a long bead but I already grind it off

He welded the entire gland nut, threads and all. I already removed the driver side but when I got to the passenger side it was all welded. I'll post a pic

Previous owner did this for some reason. What are my options? Do I really need the gland nut?

a 50trim works well with displacement up to 2.4L. If you plan on only running 10psi you should be fine. It s when you run more like mid 20s you'll notice the 50trim will run out of breath. You will also be creating more heat. I had a 46 trim on a 1.8t running 28 psi. It was fun but the 46 was under sized for the power I wanted. I could've got the same power at like 15 psi on a gt30. Remember hp doesn't snap rods the torque does.

T3/T4 turbo is a vague description. What trim,AR and wheel do you plan on using? A 60 trim will flow much more than a 46 trim and depending on the AR, boost will come on at different rpm ranges. 10psi on a 46trim is no where near the horse power of a 10psi on a 60trim. You have to look at the flow charts to see what matches your setup.
