IRP raceported engine with tension bolts, 2mm RA seals, OMP removed. Took a while but they finally got it finished. Was worth the wait. It's fed by a t04r and 850/1680's. I still have 1200 miles of break in so that's why my piping isn't hooked up.
1993 RX-7 R1
I heard you have pistons, that sucks.
Glad you're happy with it John, definitely post some videos of the engine idling
I'd recommend hooking up the turbo to the intercooler and just use your right foot as a 'boost controller' for breakin
Every man shall be held accountable for every one of his actions. The question is not 'if,' but 'when.' 1995 BB PEP (35k miles), 1993 BB R1 (12k miles), 1993 VR R1 (124k miles), 1993 VR R1 (RIP), 1990 triple black vert (167k miles)

That look nice! Are you supposed to leave the turbo like that? I thought that might over spin that turbo since it's not pressurizing an IC/IM.
Over spooling could only happen if the turbo was extremely small. It wont over spool because the turbo isn't pressurizing the engine. Since the engine isn't receiving any boost pressure, there's not enough exhaust energy or load from the exhaust to over spool the turbine. It's just like holding revs in neutral at say 7,000 rpms. The turbo will be spinning but there isn't enough energy from the exhaust under those loads or conditions to over spool it. If that were the case then you would be making boost pressure just by holding a sustained hi rpm rev while sitting in the driveway (which wont happen with a turbo of that size on this engine). Makes since?
94 Touring 5 speed 108k original miles finally blown. Date of death 11/11/06.

NA 20b now running and sounding beautifully.
Engine moved back 5 1/2"
All fabrication done by me.
Test and tune time.
