I thought I'd give another little update as to what I'm up to...
I've been a little distracted recently as I'm moving in with the girlfriend (yup, she has a whole world of car parts in the dishwasher to look forward to!), helping my dad to fix up some cars to sell, and helping the girlfriend with a house extension and picked up a little summer toy which consumed my only garage space... As such not much progress has happened... this weekend my dad had a car collected for auction, so hopefully I have work space again!
Which is handy as the FedEx man (eventually) arrived today with this...
Thanks to one of the guys on the 4GM Facebook page who knew I was looking for one (Are you on there Nathan?) who found this on Ebay for me. It's a TRD supercharger off a 4.7 2UZ.
It comes with nearly everything I need top hook it up, including the 9th injector, extra pulleys and brackets, and a Unichip to help with the management side of things.
It looks like it has been painted blue, (with red pulleys and bypass actuator) then stripped. I imagine it'll end up Red and black ;)
Unichip and P&P loom (for a Tundra lol) I've not checked the plugs and pins yet... I imagine I'll need to hard wire it in (I don't think I have room for the P&P kit!)
I also picked up some fuel rails from a Landcruiser Amazon (Petrol ones are rare here in the UK, and I have found one being broken.... just after ordering the oil filter housing from the US lol (still not arrived) I might ask if they want to sell me the sump...
The circuit board is a Bluetooth serial port. Yup... I want to be able to map my gearbox shift points by Bluetooth!
It's not all great news... It had a long way to come from Hawaii.. unfortunately, even though it was very well packaged, the Bypass actuator mounts have taken a pounding (hopefully straightenable) and worryingly the Pulley has a slight dent that I didn't see in the Ebay listing, so it must have happened on the way. The belt still fits without touching, and turning it everything sounds smooth and even, and carefully looking at the pulley there is no lateral movement at all to suggest that the shaft is bent. There is zero noticeable play in the snout! so hopefully that will be ok... I am known for being a bit fussy though.. so It's going to bug me. (Maybe I'll ask the 3th gen V8 guys if anyone has one that has upgraded to a smaller pulley?).
I also have a Fresh TRD Thermostat (71 degree.. still on the way from the US) and Denso IK22 Iridium cooler plugs ready to fit as recommended by TRD/Unichip.
I now need to decide if I want to run the 9th injector and get that mapped, or not bother and uprate the other 8. I have heard that with a modest upgrade (say 315cc, I'm 250ish now) the Factory management will cope at everything but full throttle in closed loop mode, then (safely) over fuel slightly at WOT, which will in turn be dialled out by the Uni chip as part of a complete map... Alternatively I can use the 9th Injector, so "off boost" the ECU map will pretty much run as factory, and kick in that when needed...
The other issue I have is SPACE!
I specifically wanted this supercharger kit, as I know I had no hope of fitting anything else. I needed to retain the front intake as My intake tract is set up to go to the wrong side (because twin batteries and right hand drive) and this setup is pretty clever in how it runs the charger "upside down" in the V, to keep it as compact as possible.
That doesn't totally cover it though, as it IS taller than the factory intake, and I do have my "ram air" scoop feeding the airbox which hands down.
I measured the factory inlet to the top (not including the air feed) from the TOP of the bottom Flange, The supercharger in the same way, then the Supercharger from its highest point (annoying bolt near the back.. grr) and the clearance at the lowest point from my intake.
I got these results:
Current Clearance 2 1/4"
Current Manifold Height 7 1/4
Combined Height + Clearence9 1/2"
SC height 10"
SC height with bolt 10 1/2"
So I have 1/2 of an inch to find if I can remove that bolt, or an inch at that point if I can.
That's a bit disappointing, but I should be able to find that by modifying (or redoing) my cold air intake.. I was thinking of building a new air box anyway. (and that's a better option than modifying the engine mounts, sump, headers to lower the engine)
The best bit is how I measured it
Lid for some spray de-icer, and a lump of butter on top.. build it up and keep slamming the hood until it touches!! Slamming it is kinda important, as it flexes about half an inch.. so this is accounted for. - Hopefully that will also account for any engine motion.
So starts the next phase... with more bits of LandCruiser, and a bit of Tundra from Hawaii!
The question is... Shall I do it "crinkle red" like the existing inlet manifold... or gloss enamel red?
Just kidding!
