I didn't post much info about the engine anywhere. But compression is 8.9:1. Traction with boost by gear is awesome. I running twin 4 port solenoids and 3lbs springs in each wastegate. In first I got the boost down to 2.1lbs and it actually hooks up on my 295 street tires. I have 325/40/18 drag radials in my garage waiting to go on..im going do that about a week before I go to the track though. However, on 16psi (checked through data logger) I spun from 109-123 and the speedo settled back down to 114mph..so the higher I go in boost the less predictable it gets. The scary part is..its hard to notice because the car is stiff so it doesn't pull to either side at all. Also, I don't have any updated pics of the front end..but I cut the old one out and completely redid it. I was able to get the stock hood latch to work and it bolts to a bracket that bolts to the intercooler so its easily removable.

I did the ARP 3" wheel studs and the caliper/rotor/stainless line..all in all it was pretty straight forward. My rims are RPF1 18x9.5 with a +18 offset (+38 with a 20mm spacer) and they fit perfect with absolutely no room to play. The top of the caliper has >1mm clearance but the face has more than the brembo. Im gonna finish them up tomorrow hopefully.
For some reason the calipers look the same size but they arent even close.
(don't mind the fact that the calipers are upside-down. I managed to some how do all four corners that way..haha) Im running endless RF-650 brake fluid.

Yes, the wastegates respond MUCH better with the twin solenoids. No matter what I did last year I could not get boost steady with the single solenoid.. It would ALWAYS spike and slowly drop off 3-4psi by the end of every gear. Now I get a little spike in 1-2 and VERY small spike(.5psi) in 3rd and 0 in 4th now.

wastegate only needs soo much volume to open the valve, after that its vent out the other port. Those ports can only move so much air. So my guess is that the single solenoid couldnt vent enough air from the turbo. That could cause a boost spike because the gate cant cycle the air fast enough upon spool
2 gates on a single turbo would only be necessary if the single gate was too small on too big of a turbo running too little boost

Perfect. But yes im running twin gates because they were easier to package and with the 4 port solenoids I can run my 3lbs springs up to 30lbs. I get 2.9psi in first gear lol(no wheel spin) to 4-5 psi in 2nd, 10 half way through third, then 14-18 in 4th(it spins hard if I try anything over 16psi right out of 4th)

Im pretty sure im going to be putting the car up for sale soon. Since I can't really get what I should out of it (id be looking for no less than 45 for the whole car) ill be selling it for 25k minus the engine/transmission/wheels/boost controller. (thats 20k less for 10k worth of parts lol) but the car will come complete with stock wheels aalong with the turbo kit and everything needed to swap another engine in. You could find a stock LS2/T56 for 5k on ebay and youd have a a pretty bad *** car pretty damn cheap. Im going to do another RX7 I think..and im keeping the engine for it.
