Something a bit different from what I would normally do: Noah dropped off his Supra in pieces with one request-install the turbo he supplied and get the car running on the standard ecu.

Making very sure he knew the risks of running on a standard ecu, I:
- installed and plumbed the pulsar g42
- supplied and installed a turbosmart 50mm wastegate
- supplied installed a cheap intercooler and fabricated aluminium piping
- fabricated a stainless dump pipe and screamer pipe
- fabricated the cheapest possible mild steel 3.5” exhaust with no mufflers
- installed a trans cooler, and converted to a supplied thermo fan setup
- did everything else required to run an engine that hasn’t run in years

Leaving running and driving, hopefully it gets a fuel system and ecu/tune very soon

Peter talked to me initially about tuning a very early Haltech ecu for his R31, which I politely said no to for various reasons. The car was built many years ago and reflected the typical build quality you would have seen at that point, which isn’t really up to modern day standards - very thick decompression plate, forged pistons but standard rods and no ARP studs etc.

We talked extensively about what route to go down and settled on me installing a Link Monsoon ecu in the car using the existing custom made harness it had in it with some additional sensors. I warned him about the typical issues that plague RB30 engines and we agreed we would leave most of it as is and just see how it goes, and made a booking.

Fast forward and when he brought the car down it was worse wiring wise than expected, and required me having to redo the entire harness. I also installed some Bosch 1000cc injectors at the same time.

Once done and with the engine running, we had the typical trigger issues associated with these engines, so we put a new crank angle sensor in and replaced the trigger disc with one with 12 + 1 slots which fixed the issue.

On the dyno running on dedicated e85, I was told to wring its neck, and it took 28psi out of the gt35 turbo to make 390kw before it maxed out the fuel pumps (twin 044). Joys of super low compression.

Either way it starts runs and drives so much better now than before.

John reached out asking for me to tune his Holden 5l/turbo 700 swapped Chevy pickup which he uses for towing, running a Holley Sniper 2 ecu.

I’ve found that everyone always swears black and blue with the Snipers that they’ve been on a dyno and tuned properly, but they are always set up on just the basic hand controller initial setup using the closed loop heavily and aren’t anywhere near where they should be, especially when the o2 sensor fails.

Coming in running very poorly, very rich and pinging heavily, it left running smoothly and safely, and will definitely use much less fuel than before.

Mitch brought his VK in not running to get the 308 in it going nicely.
It has a 390cfm Holley carb fitted to it which was all gunked up and wasn't receiving fuel, so it got:

A new mechanical fuel pump,
A rebuild kit through the carb and a clean,
Much, much larger jets than what were in it
Larger accelerator pump nozzle
Vacuum secondary spring change
Ignition timing set for maximum potential on 91 fuel

Leaving making 116kw with lovely and crisp throttle response

Dwayne contacted me a few years ago about tuning his Ford Fiesta rally car with an ECU Master Black. I didn’t hear from him for quite a while and then all of the sudden he walks in the door. Someone else had given tuning the car a crack and well when I had a look at what was on the ecu it’s no surprise it needed to have a new (upgraded) motor fitted.

Base timing synchronised to what the engine is actually doing, sensors scaled properly and the initial setup done right, the car now starts runs and idles, and makes a decent and very repeatable 119kw at the wheels

Minh wanted some intercooler piping made for his freshly wired GTI-R pulsar, and then to have it tuned.

I fitted up a PWR intercooler that he supplied, modified the inlet and outlets to suit more favourable piping, fabricated up some piping, an intake pipe, and made an airbox with an enclosed pod filter, all of which we then got powder coated in satin black.

Onto the dyno it went where the Pulsar 2867 fitted to it made a hair over 200kw at all 4 wheels, limited by wastegate springs.

The turbo in Troy’s rb25 powered s13 drift car that he had just purchased was much too laggy so he reached out asking for recommendations along with a tune to run straight e85 as it was running on e50 blend fuel.

After having a chat we decided on the route to go down and I supplied and fitted a Pulsar g30-660. While I was there, the injectors on it weren’t e85 suitable for the long run so I supplied and installed a set of Bosch 1000cc injectors too then on the dyno it went to tune the Link ecu it has fitted.

Wastegate pressure of 14psi made 322rwkw and 17psi made 354. Deciding that was more than enough we left it there. The awesome thing with this car is that it’s so well set up you can do 10 runs in a row and it will do the exact same power every time and run nice and cool. Big fan

Bryce contacted me about tuning his MK1 Golf with a 2L non cross flow engine fitted with Jenvey ITBs and an electronic actuator, and a Haltech ecu to control it all.

I balanced the throttles and found it genuinely straightforward to tune, without the usual intricacies of an ITB setup. I was also blown away by the smoothness of the power curve, something you usually don’t get.

After taking it for a road test I was also very impressed, 75kw might not sound like much but it makes very good broad torque and drives incredible.

A very cool car.

So it turns out I didn’t take any other pictures bar the dyno graph, whoops.

Jean chatted to me about wiring his RB25 neo de+t converted R31 skyline, and we decided that I would provide him with the combination I do all too often:
Link G4X Monsoon, CAN Lambda and a custom made engine loom and properly upgraded fuel pump wiring.

Proven combo.

He wasn’t chasing power at all just reliability, but I tuned it for higher boost also while it was in just so if he does want to turn it up at a later date he can without bringing it back.

Setup as follows:
Standard rb25de neo
Highflowed 21u turbo with 45mm wastegate off turbine housing
1000cc injectors
98 fuel

205kw on 7psi boost
244kw on 12psi I think it was
