Saw a guy with a varex dosing down the road into the servo. Sounded awesome fully opened. I complimented his car and he said it was a 3.5 inch inlet into a 5 inch cannon. He closed it and it was dead quiet...probably less than stock. He said he pulled 320 on the dyno and had cams. I might look at this option shortly.

Just had a quick look at the Varex and it's 3.5" OD, which is not too bad, taking a stab the the wall thickness of the pipe would be 2mm or less, you're left with approximately 85mm or approx 3.3" ID which is still some difference from the

run of the mill 3" exhausts. Would be great for temporarily deterring the wrong kind of attention!

Spoke to a few varex exhaust installers and they recommended not going down that path. They said the 3.5 inch canon had inherent issues when closed. They said when fully closed when cruising or in peak hour traffic, they became very hot because the gases were diverted through the muffler 3 times before the were expelled and they recommended that you would have to continually open and close the valve to help it cool down. This heat issue was causing overheating and failure of the valve motor. The larger oval type muffler did not have this problem. So I suppose it best to stay away.

I finally found the courage to comp test this engine. Turns out it's not TOO bad but definitely could be better.

155, 155, 160, 153, 153, 148.

No 6 gets me a little worried, might ask Trent to keep that cylinder nice n rich when it gets tuned.

Is that a huge issue? I thought it was only if it was around 10% out or so.

Mine came back as 155,150,160,150,155,155

Not a huge issue, 148 is getting pretty close to 10% though. Even so, as long as I take care driving it until I have money to get it tuned, should pose no problems.

    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful         
    • Legend. I ended up finding the facebook account of the owner of the first car i sent but sadly he deactivated the account. I think you’re right in saying it’s some sort of well done custom job. Really appreciate your help anyways.
