NA, supercharged, turbocharged and then V8 swapped, this Toyota ‘HPA86’ has seen its fair share of spanners over the last few years.
With essentially a ‘stock car spec’ 450HP Toyota 1UZFE V8 under the hood and the core modifications done before our ownership, the HPA GT86 has an ever-growing list of parts and ‘to-do’s’ in order to build it into a class-competitive car, and also the team's skills along with it. In the previous owners hands the car saw its stock FA20 power plant supercharged, then turbocharged, and finally removed and replaced with a stock 4L 1UZFE V8 engine with an R154 5 speed transmission fitted behind it.
300HP wasn’t quite enough though, and it later received a modified 1UZFE which has the VVTi system removed in favour of a CNC ported head, more aggressive cams and valves to match, stronger H beam connecting rods and a GM LS V8 intake manifold. Stock pistons and a 10:1 compression ratio were retained in relation to the specs the 1UZ’s used in stock car racing adhere to just for ease of purchase etc for the previous owner and also leaving the car able to run on pump gasoline.
Electronics were fitted by HPA some time ago, and include a MoTeC ECU with the Toyota 86 engine swap package, meaning all factory subsystems are retained and in use. Due to this car being street legal this was a requirement, and although we have taken things further in the last 12 months the car is still actually close to road legal with namely the aero and TTi GTO 6 speed sequential gearbox either needing paperwork or removal to turn this back into a ‘grocery getter’.
Plans are underway to partner with Hartley Engines and Motorsport to once again update this chassis powerplant with a 3UZFE based build, giving us a little extra capacity and power without there being too much for the current tyre size to cope with.

This is why the VVT-i 1UZ is highly underrated. Rev limit increase and increased horsepower without boost, also means no weight added from a turbo or supercharger.

From the gate the 1UZ has the ingredients to make it a race spec engine. Has a reserved compression ratio with overbuilt internals. Not to mention a nearly completely balanced rotating assembly. So when bumping up compression and giving it some breathing mods it's no surprise that this block can push out these numbers.

Absolutely sick build Ive been a big fan since i first saw it. Can you guys offer any insight on what you suggest in the search for more power on a budget with this engine? I’m currently planning my build for a 3uz swapped is300 drift and time attack car. I know fitting an m90 or m112 blower on it is common but it seems like a lot of money and complication for power that could be achieved NA. I also worry about how much power the weaker 3uz rods can hold and when a dry sump becomes necessary. What are the weak points reliability wise and what would you say are the first things to do when looking for more power?

Hello High Performance Academy, I'm an amateur driver and I recently bought the Cusco Type RS 1.5way LSD for my 86. I'm wondering if you decided to keep the stock settings or did you reduce the number of preload springs and/or the number of activated friction plates? Thank you, the videos are amazing!

[@hpa101]

Yes we have deactivated a plate on each side. We find these diffs to be a little too aggressive as setup out of the box which tends to cause mid corner push and corner exit oversteer.

How would running vvt not help , even just to help widen the power band by 500 rpm or to pick up some tq at lower rpm as , you could limit the deg if it works on the old 20v system , so as to have no V to P contact , Any chance of a dyno graph and one with foot pounds please 😄, Am I right that all the development of these engines are with in race rules , valve lift and compression

[@hpa101]

The engine typically operates between about 7000 and 8700 rpm and VVT really would offer limited advantage. The other issue is that given the lift and duration of the new cams, there's very little room for them to be advanced/retarded. The juice simply isn't worth the squeeze.

We didn't build a good chunk of the car so it's hard to be specific. Over $100k would be conservative though, particularly when the original owner went through multiple engine configurations before settling on the V8.

Sorry, I don't get the downshift entirely. Does the ECU time the blip to happen after the dog disengage, before re-engage? Or do you rely on the assumption that downshifts will only be done under closed, or nearly closed, throttle condition?

[@neomeg2232]

Same time. Technically the blip probably starts happening first, unloading the gears and allowing them to disengage, and the rest of the blip it's engaging the next gear.

@@neomeg2232 ha yeh i'd still like an HPA response but you pointed out that the blip will unload the box and that solves most of my confusion

[@hpa101]

The timing of each component of the shift can be very accurately timed through the MoTeC ECU. In most cases you actually want to begin the blip before the dogs disengage because when you're off the throttle the dogs will be locked on the overrun faces and the blip aids disengagement. With a manually actuated sequential we have less control because the shift barrel is moved by the driver. In a paddle shift system we can time the barrel movement independently of the blip/cut etc.
