EFR 6258 on a Stock S13/S14 SR20DET Exhaust Manifold

Well, as some of you are aware while retapping the manifold, which was supposedly made for this setup (citing issues of stock placement manifold NOT fitting with stock water lines), I broke a tap. I dropped it off at the machine shop 2 weeks ago and they basically gave me the run around and 2 weeks have gone by..........

This angers me as I distinctly dismantled the vehicle after my last event with the idea of getting the broken tap removed, the manifold returned and everything bolted up with a new tune 2 weeks ago.

With that said, I decided this weekend that I didn't want to wait on the manifold and took measurements. I luckily scored a free S13 SR20DET manifold and decided to go to work. In addition, I also picked up some banjo bolts from Kinugawa (14x1.5 to -6AN) as we all know the 14x1.5 to -6AN on the block WONT fit with the bottom mount stock manifold.

Long story short, IT FITS! In addition, the overall fitment was improved overall. This includes

1) Running a 300ZX BMC and stock hardlines, the manifold and turbo combo was much more easily maneuvered into the tight confines between the engine and engine mount
2) The v-band outlet clearance to the gearbox/engine block was much improved and clearance was increased about 0.5 inches
3) Stock heatshield can easily be clearanced to fit

This made for removing and reinstalling the manifold a breeze! I did run into two minor issues, but they are easily quelled

1) You CAN reused the stock T25/T28 turbo oil drain, but you will need a spacer as it hits the compressor housing (just use a different fitting. $10 for a proper barbed fitting)
2) Its a tight fit for the coolant lines (but that comes with a bottom mount turbo)
3) You need to clearance the stock based engine mounts to make this works (ala Nismo), Aftermarket mounts are highly recommended for this installation.

Anyways, here are pics. It actually overall fits BETTER than my prior manifold.

So in essence, if anyone wants to use a stock location manifold, just use a proper banjo bolt on the block and you are good to go!

I also decided to make new lines, so hopefully will have it back together in the net day or so!
