Did you flush the evaporator and condenser, replace the expansion valve with an r134a unit and replace the dryer? Charge the system with 2-4 oz of pag oil. Pull a good vacuum before charging for 15-30 minutes. Do you have some high and low side pressure readings with the ac on?

If your trigger is set on toothed wheel your trigger wizard will not be available. What type of trigger are you using?

Alright, Thanks. I just finished the install yesterday and wow was it easy! The car fired right up. As soon I my transmission swap is done I will update with further results.

I've played with the launch control quite a bit. I think the problem is the large turbine air ratio on my turbo. I'm hoping this new converter will help. I don't think it'll stall more than 3000rpm though... So about the cam, will the .500"/272 be a good choice or am I thinking too big? I want a winning car here. I'm planning on getting the Isky 7005-12 springs and 1624-st retainers. Roger280zx, have you done any porting to match your cam? How do you like it? Thanks

The steel liners are round. The p79 and p90 have mechanical lifters. Other than lifters and exhaust liners the three heads are the same.

The converter I just removed only stalled at 2000 rpm. Hopefully the one I just installed will get me to at least 3000. I think that's the reason my launch control isn't working as effectively. My turbo doesn't start pulling hard until 4500rpm.

We race down pit road at Atlanta Motor Speedway and there is no timing system. If I had to guess 60' times I would say about 2.50. I really just need to be able to build boost on the line which I cannot. Here is a video of the problem I'm having. I am also using launch control, cutting sparks and timing.

I would be ecstatic if I could run a 7.1. What type of intake were you running? That cam is a lot smaller than I thought it would need to run that time. Thanks

Hello. I'm looking for suggestions for a cam grind for a L28ET in a full weight 280ZX turbo. I will be regrinding a stock camshaft so I'm limited on LSA. The car will be a 1/8 mile track dedicated race car for now. I need this car to accelerate a quickly as possible. I just installed a TH350 transmission w/4000 stall to help build boost on the line. It also has the stock R200 with stock ratio (3.45 or 3.54?)The car has a P90 head on it now but I'm considering an N42 that I have to boost static compression a little. I'd like to port and polish the head and have the complete head with cam to just swap out. I'm thinking about .500" lift and 272 advertised duration...? Any suggestions? Are there any tricks say with a split pattern cam? Maybe more duration on the exhaust?...less? Not sure...What about advancing or retarding the cam? Right now, with the stock cam the car is completely out of breath at 5500 rpm. I'd like to pull hard to around 6500rpm. The turbo is a TC4305. It should be up to the task. I'm also having some intake runners machined for a custom intake that I'm building. I'll start a separate thread on that later. Thanks.

I'm using D14 to a 330 ohm resistor to the bip373 to a single coil. I guess I will have to change dwell in the ini file. Is that tricky? Also I already ordered the custom trigger disk for the L28ET that you sell. Can I still use it with a single coil? Will it make any difference? I will not be using wasted spark at this time. Thanks

I'm trying to eliminate my spark blowout with an MSD 6A box. Can megasquirt send a proper signal to fire the MSD box? It appears that the new MSD boxes are now digital. I found these instructions http://www.megamanual.com/ms2/msd6a.htm So I just connect the white wire from the MSD box to pin 36 of the DB37? Is that it? Will I still have control over ignition timimg? Thanks

Question about dampers: why is the early 75-76 damper smaller than the later (1983) damper? Is there any advantage of one over the other?

A good video to watch on YouTube is the one about how Ford started using turbo chargers in formula 1 in the 80's. They learned a good lesson about harmonics. Steve Morris runs engines without a dampener. I'm wondering if it's the huge supercharger belt the does the dampening?

I'd be willing to help get your car going.

Nice! Thanks.

A pictures says 1000 words. Any picture of this mod? Seems that my Z is only seeing the drag strip these days and I really want to make this mod.

Can someone post instructions on how to pin the shaft?

It looks ok as long as it stil mics within spec. The fsm should have the spec.

You have to pull out the oil pump and rotate the shaft. Just finger tighten the bolts and test fit the distributor until the rotor points straight ahead.

Your oil pump shaft must have been installed 180 out as long as the distributor wasn't tampered with.

Ok. I'll try that thanks. If it doesn't work then I'm switching to wasted spark.

Also need to know what engine management system you have.

Msd 8202 Turns ratio 100:1 primary resistance .7 ohms secondary resistance 4.5 K ohms inductance 8mH max voltage 45kV peak current 140m A spark duration 350uS

I absolutely fit the job requirements and live close. I just can't work for that salary.

Ok. Thanks. Do the voltage readings look ok? My dwell is 3. What would you recommend?
