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

Dom built a fresh TB45 for his patrol with a brand new turbo setup also. Powered by a Haltech ecu, it had some great wiring and an individual ignition coil conversion done locally and then came to me to be tuned.

The thing made some impressive power through gigantic 35s, an easy 248kw at the wheels at 16psi. I wasn’t keen to push it further due to lack of information on the exact specs of the build so we left it there

This r33 was one I have actually tuned and done some work on before a few years back. It has changed hands since, has been plagued with electrical issues and sat as a result for quite a while.

Finding out that the ecu it had in it was water damaged and causing a lot of problems, and that the company that made it no longer exists gave only one real option: new ecu.

The loom was in pretty poor condition near the ecu as many of these are due to various extras people have poorly added and removed over the years, so we opted to not use a plug and play ecu, instead wiring in a Link Monsoon ecu and CAN lambda and repairing the wiring at the same time.

This proved to do the trick with the car making 234kw at 15 psi on 98 fuel, and to top it off now it also doesn’t randomly die when driving

Due to the very early arrival of our baby daughter, RM will be out of commission for the next few weeks. If you have a booking already the appointments will stand otherwise please leave a message and I’ll get back to you once things settle down into a bit of a rhythm.

Thanks for the understanding!
