This all started cause a gearbox broke,

I think it was actually 4 but that's in the past and right now if I want to drive mine I go to the garage and turn the key :)

And when yours wasn't running, I could have wandered out the back, pushed the boat out and rip skidz too. Your car was off the road for a similar time wasn't it? ?

The car was pulled off the road running. I could have whacked a stock box in it, replace the turbo and it would have running within a couple weeks.

Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

Can't remember it was a few years though  was about the same time you broke your engine I think

Ok ladies simmer down.

Time to start taking bets on the power figure.

Apparently 480 AWKW was the most power out of a 8374 awkw (out of an Evo) Scott has seen on his dyno.

Nick (3.0/8374) went 461, 24 psi

Pete (3.2/vcam/8374) went 457awkw, 25 psi tapering back to 21 psi (120,000 turbine speed).

I don't know. It's all dictated by that magic 127,000 RPM turbine speed. What will be more interesting will be the boost level that it'll need to get there. Going off the -5 setup, it went 441 at 19 psi. Realistically, I should have just left it there.  Boost level I'm gonna peg at no more then 25 psi, tapering back down.

i know another evo making 450kw 8374 .92 internal gate at 36 psi

why stop at 25 psi

Because of turbine speed.

127k max. If it reaches that, the turbo is done, irrespective of pressure. 

Its no secret that these things have certain parameters to keep within, just like any mechanical part.

What speed are you at with your 30 or 32 psi?

and you know 25 = 127k?

is it to keep them alive or are you saying it wont anymore power beyond 127k

i was about to turn mine up to 34psi haha

No I don't know 25 psi will equal 127K. It was an educated guess... I could be well off. We will know because the speed sensor will be going back to the ecu.

Hopefully the wheel doesn't end up out the back of the exhaust. You're bloody crazy to turn it up that much without knowing what it's spinning at. Not the turbo's fault it if fails.

      I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed

      Recommendation for engine oil funnel spill free

      By MBS206 · Posted

      I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.

      Fuel Pump Control Module & Dropping Resistor

      By EndZee · Posted

      Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
