Anyone have a passenger side tail light trim without the light that they are willing to sell and ship to me? 78 280z. Im in Idaho. Thanks!

Ok, I found them at datsunspirit thank god! Hard to track down those things. At least standard size is. They wanted quite a bit of money for em, but thats the price you pay for a hard to find item I guess.

No you cant. Not standard size. Ebay shows them but when you buy them you are refunded because they dont have them. Tried it already.

If nobody has any can anyone point me in a direction to find them as they are impossible to find as far as I can tell so far.

I am looking for a standard size btw.

Like the title says, I need a piston out of a 81 to 83 280zx non turbo. This is the flat top piston. I only need one and I don't care if it is attached to a rod or not. Let me know what you have!

Lowrider....can I see a picture of your external setup? Did you weld it to the exhaust manifold?

It doesnt now, I cut the gasket out. I think it really is the size of the wastegate hole here... My goal is around 18psi...but to do that I will need injectors. Im going on the z31 turbo injectors at the moment.

I want to avoid an external setup if I can. I made a 1/2 inch hole between the scroll ports, and bored the wastegate hole a little bigger....No difference. So, I will try and bore it more, but I really just dont think the hole can be made big enough. I also have a bit higher compression, 9:1, so maybe thats contributing to that. Seems to climb to about 14 or 15psi now and stop. I guess thats an improvement. Thanks for the input guys, Im going to bore that hole a bit bigger if I can and see what that does.

Thats raises a great point Leon. However it is the stock downpipe flange that was on the turbo and the stock internal gate flapper. Yes the flap does open, however I did remove the dp flange and saw that the gasket was warped a little. For some reason they made the gasket the entire surface of the flange instead of just the outside. Im gunna try drilling out my hole, drilling a 1/2" hole to the other scroll side and cutting out that section of the gasket to allow the gate to open more. Im out of ideas if that doesnt fix it.

So I turboed my Z and added an HX35W to the mix. I changed the actuator to the internal gate for a 5psi spring that I will later control with a boost pressure controller. Heres the deal.....the internal gate doesn't seem to do anything at all with my boost pressures. I can apply 5psi of compressed air and the flap opens with the actuator, but when I get it on the road, it just climbs like there is no wastegate at all. Its not creep, as I have heard that this internal wastegate will creep a little, because it doesn't even attempt to regulate the pressure. As in it won't even slow down at all. Just 0-12 in a blink of an eye, then I back off. The turbo is a twin scroll, and I am using the stock single scroll manifold. Looking at the wastegate hole in the turbo it seems like the hole only effects one side of the scroll.....anyone think this has anything to do with it? I have searched and found nothing so far....

Yeah thats exactly what happened.

I verified with a degree wheel....I think I might have found the issue though.... Aside from total advance, I was on the track today and noticed I was getting a misfire in lower and lower RPMS. I looked at everything spark related and found number 6 spark plug just sitting on the plug not snapped in....hmmmm.... I snapped it back in and needless to say I need back on that dyno. It's been running with 1 intermittent cylinder which would explain why it was starting to misfire at around 5800. There was too much resistance at that high of an RPM because the plug wire wasn't snapped in....strange, I don't remember not putting on a spark plug wire right... I figure after advancing the total timing on the dyno as much as I can, if I want more power.....well....there are options...

Here are some pictures of my cam card and the dyno run...the cam is custom. Sorry about the card being dirty, I spilled coffee on it and cussed like you wouldn't believe. The lift is 432ish at 1.5 to 1 rocker ratio and duration is at 264*. As far as the distributor...I have a CAS style distributor from a 280zx turbo with a 300zx wheel in it. Like I said I can control my timing to anything I want through my emulator at the EEPROM. And yes I have flattops
