Can see a wideband sensor fitted in downpipe in above photo started installing the unit for that under dash too.

Started some wiring fitted looks mint pity you can't see it for throttle body..... suppose that is the idea. More to do just a bit of soldering to finish off and put in braided sleeve so it can shed heat. Discovered the ignition coils could flip 180 degrees bolt straight back on and wiring is basically perfect once unwrapped reaches dead easy and won't melt on wastegate, heat shield will be a good idea though. Airflow meter new location on right side of engine bay set up in photo.

Nah the throttle body and airflow meter sit right on top of it where filler cap was now. The cable bracket was 1-2mm away from it so had to move. Other side is actually fine just needs a funnel I suck at pouring anyway.

My crossover pipe ended up clashing with chassis rail has ended up becoming a stupid complicated thing only really so it fits the existing pipework locations..... I may end up chopping it off and have it enter just under the turbo instead of the collector, as I think it may end up been a restriction. Also time to fit the wideband sensor I bought ages ago off @Honda Ass Dragger and it integrating into the pcm.

Not much to see but have flipped rocker covers over so i can access the oil cap wouldn't want to top up hot but you get idea. New gaskets too billet cap so it doesn't melt.... Have started on wiring not ultra complex but coil packs need to move.

Apparently you can use LT parts on them like manifolds and lop 2 cylinders off. vvt sounds extra cool for a push rod donk. Saw a cranky one pop up on insty sounded fierce!

Have decided to do rocker cover gaskets while I have access and flip covers drivers to passengers side vice versa as the drivers side now has a throttle body on top and passengers has ample room between the downpipe and wastegate to get a funnel in. Bloody repackaging can see why they never did as a factory option.

Yeah I'll go nuts with heat wrap and make some shields. I'll build a box myself later on they cope ok at 400hp will stick a shift kit in asap ive already bumped line pressure up in ecu.

Back on track again everything that needs to go back in engine bay is there wiring has been started everything accounted for. A v6 engine bay is normally quite empty looking this one's bloody packed! Bonnet shuts exhaust now misses the air-conditioning components phew taken long enough. Hotside needs to come out again for some welding after re jigging the up pipe but that's a 5 minute job now.

Well first cock-up found.... up pipe from cross over doesn't fit needs a zig zag easy fix I just didn't account for the depth of engine bay when making on dummy block Zach stripped the exhaust manifold off for me and made a start on wiring for too surprisingly once unwrapped all but a few wires reached the drivers side where airflow meter and throttle body is.

The size of the hotside assembly off the engine is quite considerable and looks mental when you pick it up and turn it around to check things out. I'm very happy with my driveway cobbling together on this occasion

Now the exciting part bolting on shiny cool new stuff!

Look at all this space!

Had to re engineer the throttle cable bracket so it clears the inlet pipe made that work with the grinder that's been in naughty corner after bumper support....... Spritz of paint it bolted on and the cables even work in their new position although very long I think I can hide this by sending them under manifold.

Turned key on this morning primed fuel system amazing no leaks! Continued on with the inlet manifold flip managed to get that all squared away of course a few things no longer fit like the lid for the plenum. A few bolts no longer lined up some did its seen a lot of welding. A bit of filing drilling and slotting of some holes and it all went together.

This drag day It'll be fast or legal probably not both or broken. I'm surprised it's still alive it's done countless rips down a runway drag passes and road trips gravel drifts and alot of that was done running on kerosene It's earned its keep and some upgrades. Looking forward to some roll racing so I dont scatter the 4L60E all over track.

@Roman I've reached out to an Ozzie group on Facebook and a guy is running same size setup behind the bar requires some bends fitted but that's easy in scheme of things. It's just occurring to me as the RTV on my intake is setting I need to weld a AN6 fitting on my fuel rail for the new regulator..... shit. Pushing through analysis paralysis and fucking things up to see what the problems are surprisingly is some times an effective way of nutting things out.

Happily everything ordered so far fits injectors dropped right in, were a snug fit I haven't dare prime pump yet may piss fuel everywhere. Better add that to whiteboard before I go to far.

Here you can see I now have throttle body facing other side of engine bay this may or may not create a whole pile of new problems like wiring and throttle cables fuck it I will cross that bridge another day for now onwards and (Possibly) upwards.

So ignoring the elephant that is my Intercooler for now...... I ripped my happy running car to bits and started to fit parts from the internet, reverse plenum I kind of redid and my 850cc injectors

I've fucked around with gas shielded Flux core did around 90 metres worth on a big meatworks shutdown then had the thankless job of laying hard face on top. By middle of job I was as good as the old timers. Been experimenting with 8% co2 argon mix on tig lately mainly because a free G bottle is worth a squirt, no real ill effects thought it would kill the tungsten not really any different though im back about 5 amps from normal settings. Saving my pure argon for the stuff that needs it.

I might just go small less problems, this cooler came as part of the Tony's Turbo Garage kit i bought and chopped up. Can save this setup for non road events.

It blocks the top 120mm of cooler and is a big square tube... quite annoying

Second cock-up of my build picked up by @cletus ive chopped my bumper support and that was silly. What are my options? If i move the intercooler behind it the top of intercooler will be blocked and all of my air conditioning will be in way. I can fit a smaller intercooler and just suck it up and see if it limits air temps. Can I leave the intercooler where it sits now and fabricate a replacement bumper bar from tube that uses the intercooler as the collapsible section? Can get Dave Bray chassis shop to help out here (my preferred option) What's going to please a certifier more? It will see the track but I don't want it getting there on a trailer.
