This will be my next swap

It all depends on how deep your pockets are. I personally know of a 73 240 that has a 2300 maggie supercharged LS2/T56 that will be coming up for sale soon. The car was stripped of it's driveline to be repainted and checked over for any signs of cancer because a bubble was found on the bottom of one of the doors. Luckily, that was the only spot on the entire car. I know, hard to believe and I wouldn't have believed it either had I not seen it for myself. Anyway, the car is now being reassembled to be sold. It has almost everything you are looking for with the exception of a wide body kit and roll cage. Dyno sheet available to show over 500whp. It won't be cheap but would be a great start to what your overall goal is. if you want to know more about it, shoot me a PM. Joe

What do the plugs look like? Have you started with a fresh set? IMO, when you are trying to set a base tune, you will be going through ALOT of plugs. Post a pic of the condition of the plugs, buy a few sets of new plugs, make sure you 100% accurate with your trigger wheel offset calibration and we can start from there. Joe

This ^ !

I just realized I never updated this thread for people who were following. Well the problem was always timing. The biggest issue was the way the Quad Spark was wired. The way it was wired, coil 2 was in coil 1 position and coil 1 was in coil 3 position. Obviously that left coil 3 in the 2 position. When I was setting trigger offset, I was checking when plug number 1 was firing which was firing when cylinder number 2 should have been. Following? I know, a huge cluster f. I only found out what the issue was when I tested just 1 coil. I tested coil 1 and low and behold, cylinders 3 and 4 fired! I ten check the others and none fired the cylinders they were supposed to fire. Now I could have just moved the plug wires around but that would have been too easy. So I rewired the QuadSpark the way it should have been. After that, the got the plugs firing in the correct order and then reset the trigger offset and the damn thing fired right up! So yeah, I'm now an expert on wiring this damn thing lol. Now to finish up the tuning which I have been slacking on.

I figured out ignition offset. Got that set now. It was actually 66 degrees lol I just got the injectors back from being cleaned so I know they are working but I'm really at a loss now. I can get the engine started but lets just say it isn't running correctly. I threw in a set of fresh plugs and it started a little easier but then the AFR's went way lean and there was popping out the exhaust, caused by a miss. Pulled the plugs and this is what I find. I've also attached the log file of the start. Any ideas??? 2019-06-06_00.41.37.msl

Ok so a little more information. The TEC CAS mount put the CAS at 84 degrees after the missing teeth at TDC. So I now have 84 degree set for missing tooth #1 angle BTDC. I originally had this at 66 degree as that is what I had it set for on the TEC. I figured that would do it but not quite. What are you guys using for crank advance and can anyone share their ignition table? Thanks Joe

Yes. Appropriate cylinders are firing. Waiting for another set of hands to check base timing with a timing light. Hopefully today.

Hi Guy's, Man am I having trouble getting this thing to run using the new ECU. A little background, the car was running fine up until I decided to "upgrade" the ECU lol It has been running for over 10 years using an Electromotive TEC II. Switching to a MS3 Pro. I'm using all of the same sensors that I used on the TEC. coils are DIY's 3 pack running in wasted spark mode. First attempt, it started but didn't run very long and was pig rich. I looked at my old TEC tune and noticed the required fuel was a lot higher on the MS3 so I dropped it a bit. Same situation, started, but didn't run for long, maybe 4-5 seconds. So now I start troubleshooting from scratch and find the first coil in the pack isn't firing so basically I'm running on 4 cylinders. Gotta be it! Not quite. To make this part of the story a little shorter, the Quad Spark that I received was defective. It had the output going to that pack grounded so if the Quad Spark was mounted, no spark to 1 and 6. Now I have a new QuadSpark but she still won't run. Spit and sputter but that is it. Since I am using a trigger wheel that I mounted to the balancer for the TEC, I'm starting to question myself on where I have the pickup mounted. I'm sure the pickup was mounted at the 11th tooth after the space would put it at 66 degrees but..... Did everyone else have this much trouble getting their MS3 to run? Joe

Sad to say, I haven't been on Hybrid in quire a while. I came back after being one of the originals (anyone remember the mailing list?), because I tried to update my turbo 240 from a TEC II to MS3 to take advantage of all the new stuff that the MS3 has to offer. So what did I learn so far? I should have left well enough alone lol I had the TEC running very well. The MS3, can't even get it started! This old guy either forgot way too much or has a lot to learn. Maybe both! Just figured I'd post this here after searching for a while to give you guys some laughs Joe

Hey Bob, good to hear from you! Unfortunately, social media has caused a tremendous decline in the amount of traffic HybridZ now sees. Your best bet would be to list this on one of the many Facebook groups created for the S30. Also, depending on your final number, the setup might just end up in NJ :) Glad to hear you are still Datsun involved! Joe

I'm still here as well but like I do every 8-10 years of so, the Z's have taken a back seat to another ride.

Not sure if everyone here has heard but we have lost a wealth of knowledge on Z cars. John Coffey had a fatal motorcycle accident yesterday. RIP John.

No can do. I'm using hubs based off the 300ZXt and have moved the rotor and therefore the caliper outward to fill the void created by using the 350Z wheels and their +33 offset. The hats are for a 55-57 Chevy and work fine lol

You have 12 bolt mount on your hubs? Lucky dog! I only have 8 which greatly reduces my rotor choices.I was limited to 13" rotor because of this

Do you mean the leather shifter boot? If so, I used the boof from a 2004 Mustang Cobra and mated it to the console. Fits perfectly!

255/35-18 on 350Z track rims. No issues.

Lucky? I don't know if I would call you lucky as this is the first time I have ever seen a rollpin back itself out! Glad you didn't have to pull the trans to get her back together. Happy Thanksgiving

We're still waiting for your driving vid!

This. I'm sick.

Keith, Are you married to the 28 inch tire? I think a 25 inch tire and a 3.9 diff should get you close in 6th gear. You have a GTO trans right? that's a .56 6th gear. Joe

One thing I've learned from being on this forum for since the begining is this guy ^ really enjoys his Z! Ain't no sitting around saying "I should have", "I would have", "I could have". Nope, Keith does it! Joe

We dropped a 2300 on an LS2 in my friends 73. Bone stock with the exception of long tubes and the huffer. It made 503 on a dynojet and has yet to be tuned. She's not even breathing hard!

I think the reason there isn't one already available is because it can't be done for that price. The problem is the chunk of aluminum needed to make the billet cover costs $350 by itself. Adding bosses and or different stud spacing is not a big deal and I'm sure can be done without additional cost. Joe
