Dyno Comparison For Each Part Added

Yes, this car drives better and handles better than factory thanks to the HKS coilovers, along with having around 100+ more rear wheel power than original. This will be more than enough for our customer. For the past 12 years or so, he had countless visits to the Mazda dealer trying to figure out the LIM gasket issue, so the car was down around 150hp due to no boost. When I gave it back to him last time with the 254rwhp, he was amazed. He will be picking it up this Friday.

We do not have emissions testing in our state. The Lambda/wideband are perfect even leaner than the factory ECU, which is documented in this thread. Everything else we do not test for and do not need to.

In this thread from last month I did back to back testing on just the HKS twin power install. https://www.rx7club.com/3rd-generati...rison-1103125/
As I said there:
Doing that back to back test is actually what gave me the idea for this thread.
As I said there:
Any changes to fuel, air or ignition should at least have the AFR's verified, if a substantial change is noted then a tune is required. The car above was already at the shop for tuning, the first run the AFR's were stable but the ignition was not, installed the TP for the next run and the AFR's were still within acceptable range. Then proceeded with tuning the car.

Changing those parts doesn't affect emissions when the engine is warmed up.

IAT's stayed in check, never really got over 56C, that was with back to back manual load runs during tuning. Let it idle for a few minutes and they would drop down into the 40's. Nothing like the stock air box and IC where I see above 100C regularly.
It should be noted that the hood is always open on the dyno and we have some incredible fans.

100C!?
Would have been really interesting to see a back to back with the open intakes vs the stock (or modified stock) airbox with the upgraded intercooler and PFC in place, just to isolate the IAT change from the intakes. Not complaining; I know you couldn't test every possible combination.
Only wondering about that because I recently replaced a similar "hot air" GReddy intake with a modified stock box and was surprised I didn't actually see much difference in IAT.

Correct, unless I wanted to spend a month doing nothing but testing different combinations. Which I really do not have that much time to donate considering there are 15 customer cars in the shop. This is why I laid out the project from the beginning without the option for swapping stock parts back on.
I have found the IC to be the biggest problem with IAT's. Open air intakes allow the engine/turbos to breath properly, then it is up to the IC to bring the temps down. Not surprised that you did not see any reduction, I would be willing to guess that you lost a few HP however.
If someone wants to send me a modified airbox I will do back to back testing against stock and an open intake the next time the opportunity arises, logging IAT's. I will even start a whole new thread dedicated to it.

Talking about IC, I see there is a Greddy unit on your website that retails for around $700, but I did not see if that is a stock mount unit or a front mount unit.
I am on your website right now putting a budget together to do all this to my car to hopefully get similar results.

Greddy does not offer a SMIC through distribution, they may still offer one direct. Greddy has some strange rules when it comes to the parts they allow distribution to offer.
All the Greddy intercoolers on our site are FMIC's with exception to the V-mount kit.

We install a lot of Pettit Cool Charge III's for twins and even on some single turbo cars. It does however require the battery to be relocated, which this particular customer did not want to deal with the maintenance of a drycell. The Pettit CC III limits the intake that can be used also. Here is another one of our customer's cars with it installed.
