Morning all

I feel so dumb asking this question as i did 4 years working with these things but is the Trust T78/T88 manifold actually a twin scroll manifold?

We are upgrading the T78 turbo to a Precision Turbo 6766 and want to make sure i get the right housing

The manifold and turbo appears to be split pulse/twin scroll as it is divided, but i had this idea in my head that it needed to have separated, twin wastegates to be a twin scroll manifold

Help would be greatly appreciated as i am about to put a deposit on the new turbo any day now

Thanks in advance

Brad

Does not have to have twin gates to be a twin scroll. Just needs the single gate located in the right position. At work can't full explain.

All the t78/88 manifolds I've seen are twin scrolls.

Thanks Josh

I have neevr actually looked at, or thought about, twin versus single scroll turbo's and now that we are going to swap the T78 for a 6766 its something that has been asked

I nitially just said an open turbo, but glad i looked as i would have made quite a costly mistake

If you have a TS manifold and can get a suitable TS turbine housing then you should have gains low down.

At the top end the divider might cost you a little.

I would go for the TS housing since you have a suitable manifold and enjoy the better response.

    • 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.
