i decided to try to redo my Autometer shift light by 3d printing a new "guage insert" to hold a LED shift light and the shift pill.   Starting to work though the component sizing/

Biggest vacuum leak of all time!

So my engine was sent to the machine shop this week, and I was dead set on a 800 whp boosted build. However, I am contemplating just going for 450 whp NA, so I am curious on what combination to get there and still be a daily. So far I have collected that I will need:
243 Heads
Fast Intake or what can I reach power wise with my LS1 intake?
Cam (not sure on what spec, researching it now but open for suggestions)
I am sure I will need valvetrain to go with the cam

Since the block is getting bored over, I can do a bump in compression too so open to suggestions on this as well.

So all in all, I am researching now but wanted to open up a thread to see what others have done and any information to help clear the water on if I want to resume the boost idea or just get the car running faster and go NA. This will be going into a FD RX7 with a T56 tranny with a 8.8 irs diff. Anyway, any info is appreciated and I appreciate the help.

which flange is the driveshaft for?

4.10 or 3.9

Stock diff in a JDM 1993 Efini soooo... 4.1?

Check out the wiring diagram here:

The diagram you need is on page Z-24.

BTW this diagram is shown in the "General tech how-to guides" on the NoRotors site.

It looks like the easiest way to trigger the relay is to break into the Black/Red wire at connector X-11. If you want to bypass the clutch safety switch, put a jumper wire in the A1-04 connector.

Please note: I've never worked on an FD, I have an FC, I'm just going by what I see in the wiring diagram. FD experts may want to chime in here.
