850cc injectors mounted, sr20 rail made to fit. They should give me some headroom for more boost later.

 

Plenum is done, I got a little carried away on the top cover ;-)

 

I believe a plenum should be a minimum of double the engine volume, so at least 4L for a big bore 3t (~1950cc) not sure about the max volume? The bellmouths / trumpets should never be flush with plenum wall / floor, they should be raised. The reason being the slowest moving air is always at the boundaries of a plenum / pipe and the fastest at the centre. These might be too long, but they are the shortest dhla/dcoe ones I could find. The 4th cylinder opening is roughly half way in the plenum. Ideally theyd be slightly shorter and have a full radius instead of half radius.

 

Plenum volume can be between 1 and 2 x the engine capacity, 2 x usually used on engines producing well over 2 hp per cc.

 

Hypertune plenum

 

 

handy little chart, number 11 is what i was referring to.

Thanks mate, I remember seeing a chart similar to that quite some time ago, I guess these trumpets would be closest to #9 with the back edge of #3?

Been a while since I've posted. Put some solid hrs into getting it running but had a run of bad luck.

Had an injector die, bricked my ecu, lift pump failed and wideband died.

 

Despite that, I got it running (no wideband at time of video) yet to tune it.

Made some pretty big changes, removed the coils and igniter module and replaced with logic level COPs to diagnose a miss / breakdown of spark. But it turned out that I just needed a 10k resistor on my VR sensor... ah well.

 

Ive also changed the turbo to a gt2560r, running a techedge O2 controller and switched to e85.

 

Have road tuned it and its hauling ass, quite easy to break traction in 4th without much provocation. Very happy with the results, the only thing holding me back now is the clutch can't cope with the big increase in power.

 

I have a 1g-gte 225mm flywheel and bellhousing and a w57 here for it. I have gone with CI's ga70 225mm sprung button clutch. This setup should be spot on.

2560 and e85 is some nice progress, will be a little weapon.

Thanks mate, even at 8psi its already a handful. Once this clutch is in I'll bump it up to 14.

Damn this thing is cool!

Great work on all the changes since the NA setup, any updates?

Hey mate, yeah lots and lots of work since.

 

I'll put some updates up once I get a bit more time, but for now I'll just put up a picture :y:

Lol snowballed is am understatement! Let us know what you're up to when you get the chance.

A few updates for you guys.

 

Built a side pipe for it, this is it idling.

First time drifting it since the turbo conversion, track was really wet.

 

Later in the day, drifting in the dry:

 

 

 

 

Testing the rear bumper cam

 

 

 

It violently transitions between traction / no traction and over / under steer, I think mostly due to the spooled diff.

 

Makes for a pretty fun ride :D

 

And this is the actual turbo setup being built for the 3tgte, a Garrett GTX3067R Twin scroll 1.01 rear housing.

Aiming for a lot of boost, hoping to hit 400rwhp :D
