Internal wastegates are always a compromise, (except with the new BW turbos). They never flow well as the exhaust gas cant turn 90 degrees out of the wastegate port when its doing supersonic speed through the nozzle. Making the port larger will only mask the problem, I have also tried grinding the port to allow better flow and it made no difference in that case.

Plenty of gt3076s with internal gate make decent power and as for internal for stock turbos lol stao doest have a problem making well over 300 with internal

never said it cannot be done, but u clearly have never been down this path yet. some ppl like to learn the hard way :)

I was done that path with my old rb25 with a gt3071 on 270rwkw internal Gate and also a gt3540 internal gate on my rb30det making 346rwkw

Like I said I'm not goin to cry if I only get 290rwkw the mafia made that on 17psi with the sump pipe I bought of him which was custom made separating the internal gate and exhaust and made 315rwkw with meth injection with no mods done to his turbo

and i dont have a ex gate setup on the car atm im just buying a external gate gt3076 swapping the rear housings as i bought a dump pipe to suit

worse case ill just weld the gate closed and blow a hole on the rear housing for a ex wastegate :)

So gtscott do u think I should just buy the Garrett wastegate?

If you have the option get yourself the garrett big can item :thumbsup:

Apparently they help spool on a little earlier, but I honestly didnt see a problem with Mick_o's one (his is the small can they normally come with)

    • A few small updates since the previous post and lessons. I decided to do a little interior light upgrade on the 110. I quite like the iilumo items, even if they're a bit of a premium over other brands. You'll also note the Stedi Fogs, that will go into the S15 fog lights as I needed to match the bulbs since I got the new ones earlier. I hope they fit as the body is quite a bit longer than your normal bulb.  Annoyingly, I managed to trip the fuse, which normally wouldn't be an issue until I located the fuse. I can't say I've ever come across this. I had lucked out that someone nearby had a spare, but oddly enough Toyota dealerships seem to keep this in stock. I ordered some to keep in my stash and as luck would have it, someone else nearby tripped the same fuse so I passed on the favour.  I also did a little service on the 110 ahead of some additional work coming up. It's been annoying that Goleby's stopped carrying this particular HKS filter for the 110, so now I need to keep them on order from Japan. I also took the opportunity to install a bash plate and number plate riser. The plate riser is such a cheap but nice fix to help really tidy up the car. I'm tempted to now also replace my headlights, on this car. Both items were from Project Aero.    I also needed to replace the rear tyres on the 110, and after trying to get it aligned learnt that I need to replace some bushes in the front end, so that's next.  Closing out this update with a nicer picture as always! 
    • Yeah mate, never miss it.
    • Any going to watch World Time Attack at SMSP this year?
    • Appreciate the correction on the "ground", that will make a huge difference to looking at this. That makes complete sense about AF70/AF71 which is what I had come down to being the issue, one of these. I'll have another look in the ignition wiring when I get a chance next week. I'll also make up a jumper wire for running that AF73 test.  ECU is fine, relay itself is fine, pump harness is fine and the pump itself is fine. I am going to upgrade the Walbro 255 anyway with a DW300 I have since I need to replace the fuel sender and I'm going to upgrade the FPR with my chasebays kit ready for new plenum/injectors/dbw, but I'll get this working first. That's why this is so frustrating.
