You're moving right along there.

 

If you see any Z31 turbos in your junk yard, grab the turbocharger. I believe you can use those on the L28. Also, grab its ECU, MAF (na Z31 also), and the crank angle sensor out of the dizzy of any Z31. Do a Z31 ECU swap. Its cheap and a much better system. You can try to see if the electronics you have work... but mine still don't after cleaning them up and repalcing every major component.

 

I like the new wheels. Keep at it. See you in Port Townsend on the 19/20th ??? :)

I have that Z31 turbo its pretty cool it has a water cooled bareing section. I would shell out 3-4 hundred bucks for megasquirt. get some bigger injectors too. Maybe use your short block from your N/A engine that way you have a little higher compression and a better responce off the line but if you go that rout you will need to put an Intercooler, and while you're at it port your intake manifold for the 60mm TB off a 240sx. If you are looking for close to 250 WHP or so those are some of the things I would do to get into the range. But it depends on how much HP you want, and how much cash you are willing to spend. Good luck and keep us posted .

 

P.S. Great post! :burnout:

still have to wait for gaskets .parts store didnt get them in .also they dont have the manifold to turbo gastket ..do i have to order that from MSA ??

Only after i get turbo motor running , will add on my 240sx throttle body and ported intake. mabe a z31 ecu setup... i have found it best to get a older motor up and running strong befor you start boosting it up a bunch..make sure everything is in working order.then do some mods and see how she takes it ..

tomarrow is another day .mabe i will get something good done with it :icon10:

wow, project seems to be moving at a good pace.

 

I agree though, it's always nice to get questionable parts working before you go and modify something that would put more stress on it and such.

 

Oh, and you meantioned a 5 speed conversion. Your ZX didn't come with a 5 speed? I didn't even know the ZXs had 4 speeds at all, and i've seen a fair amount of them.

Nice job. The car is comming along nicely. I wouldn't bother spending time on painting the exhaust manifold though. Unless it's a real ceramic coating it won't last much past your first run..

I figured that much on mine. I used 1200 deg white paint. It still looks perfect and I've driven over 1200 miles on it. (turbo)

Looking great!

 

For all your gaskets you can get them cheaply off eBay or from http://www.roadraceengineering.com - thats where I got mine.

 

I would recommend Jet Coating your manifold, too late now as you have it all painted...but its a better coating that will keep the heat in the pipes and last a VERY long time and good to 2500F

 

Here is what their hottest coating looks like (also avail in black). This is my current project as well:

gray tryed to get the intake off that junk yard car yesturday...it was on a 78 280z with a n42 head ..

IT wouldnt come free .

ex bolts are striped ..so i said hell with it ..i wanted that intake just becuace i thought it wouldnt have a EGR but it did :icon50:....

so after reading some other posts. i striped my turbo intake and will be going with the 60mm throttle body setup ..i ported out the front with a little grinding wheel ..going to get a long wire wheel and do a lite port thought out the hole inside . found the post on not needing the spacer so iam going cut and tap my 240sx throttle body arm make a gasket , and just use a coupler for the j tube ..
