Looking good. Have you thought about doing a turbo swap instead? The stock bottom end in the L28ET is good for 300rwhp and it's a fairly simple swap.

Are you talking about the sheet metal? If so there isn't anything available to my knowledge other than a parts car.

So the moral of the story is have lots of clamps....

Looking good

We sell rebuild kits for the stock harness which includes all the main connectors in the engine compartment. You could also splice in a new harness to an old connector but that's kind of Mickey Mouse.

TonyD is probably referring to the Electromotive 280ZX turbo race car with 1100hp in the 80's. Impressive to say the least. I think the headers look fantastic Xnke. I'm sure the marks from the mandrel bender will have little effect on the performance.

We can do. The problem is the stock ECU main connectors are not available

Just run some extra wires from the fuel pump to the meter and put it on the dash, etc and you can monitor the voltage as you drive. You can use a small gauge wire as you are drawing a very small amount of current in the meter. You can check out some of our projects at www.mackaypowerproducts.com Running a stand alone EFI system is the ground work for optimizing the performance and fuel economy of your engine. You also have the added benefit of being able to monitor what is happening as well as data logging and analyzing after your run. You could also for example add a fuel pressure sensor to the rail and monitor your fuel pressure which would make resolving your current problem a lot easier.

Adapter cable plugs into the stock body harness to connect to the 81-83 style relay kit.

A relay is an on/off switch. If you give it a signal to turn on its on (unless of course you can supply enough current to turn on a relay which is less than 100mA). Check and verify what you think the problem might be. If you suspect power to the pump then check the voltage at the pump. We do a lot of custom relay and fuse block assembly that plug into the stock body harness for MegaSquirt and other stand alone EFI systems. For the 81-83 we reverse the control logic and run the stock relay. On the 79-80 with the larger relay we make an adapter harness and drive the fuel pump directly through the large fuel pump relay near the headlight sensor in front of the passenger Strut tower.

Looking good - keep at it!

Since you are in California I guess it's an average price but for the rest of the world it's a steal. You guys are spoiled when it comes to old Datsuns

If you are hyper miling then you can likely get 30mpg. Comparing 1980 technology with 1993 technology isn't rally apples to apples though.... you are way further ahead with a 1993 MR2 4 banger than a 1980 6 cylinder developed in the 1960s....

Absolutely it's something that could be done of course. You would need some sort of cam sensor if you want to run full sequential spark. If you are happy running a wasted spark setup you just need a crank sensor for spark timing. You will have complete control over the timing and make whatever curve best suits your engine. The nice thing is that you can always upgrade down the road to injectors of you want to add that. I recomend running an LS coil of some sort as they have a very hot spark and the ignition driver is built into the coil.

We can build pretty much anything. We did an LS1 in an S14 putting down 400 rwhp. You could run MS as an ignition system but if you are going through that effort you may as well take full advantage of an EFI system and run the injection side of it as well. There's a reason manufactures run EFI in modern cars as you can have the best of both worlds - max performance and max fuel economy - just depends on how you use the throttle

So after almost a year of building MegaSquirt harnesses and pre configured MS units I've finally had a little bit of a lul in the action which let's me have some time to work on a complete custom body rewire on a VH45DE swapped 240Z. You can check out some of our builds at www.mackaypowerproducts.com

There isn't anything as satisfying as overcoming adversity

Oh yes! I've been waiting a long time for this post - Woohoo it's alive!

The stock system is designed to run at 7 psi with the stock injectors. What do you think happens with the stock injectors and stock fuel management when you run it at 25 psi and no intercooling? Its not so much the scalding air - its the extreme lean conditions and detonation that would be the problem. Surprised the thing runs at all....

S13 coilovers

So what's the latest and greatest with the rear swap kit?

Interesting for sure. The things we do know make a difference I'm not sure if you've done yet - wrapping the manifold, turbo blanket a at least the down pipe makes a significant difference first for performance and secondly for keeping temps 8n the engine bay down. Secondly ducting to your intercooler will have a significant effect on its efficiency

You'll want to go through the 1983 FSM and follow the trouble shooting guide. It will find 95% of most of the problems with the stock EFI system. Have you done the basic stuff like timing, new cap, rotor, wires, plugs, replaced old vacuum lines, compression and fuel pressure test, etc?

I keep looking for the "like" button

Yes we are at www.mackaypowerproducts.com if you want to see some of our builds. Just finished off an LS1 swapped S14 240SX which we will hopefully be posting some pictures/videos of soon as well as Dean's VH45DE swapped 240Z.
