After all the stars finally aligned, we managed to get Chris’s BF sorted with a G40, ecu relocation, fuse box relocation, a fresh set of 1650cc injectors and a built tailshaft, and it was finally time to see what this absolute gem could make, and then send it straight to power cruise 😎

Still rocking the cast Hypatec pistons and Spool rod combo that we use in 90% of our builds, we wanted to push this thing and see just how far it would go, and it certainly didn’t disappoint! 💪

We managed to squeeze an impressive 670rwkW/900rwhp on 27psi @ 7000rpm before running into a fuel supply issue, which I suspect is now coming down to the factory fuel lines becoming a restriction.

Even with an in-tank surge tank and twin 460 pumps, we’re starting to find the limits of the factory fuel lines!

670rwkW on cast pistons, and there’s still more left in it! Killer result from Chris he has built the motor, the zf6 and the diff himself and has been perfect since 🙌

Hey guys!

Been pretty quiet on the posting lately, but we’ve been busier than ever behind the scenes! Huge thanks to all our loyal customers for keeping us flat out, the support doesn’t go unnoticed! 😁

We’ve been smashing out a fair few Cruisers lately, and I’ll tell you what, these things make some incredible gains with the right tuning!

The best part is, you don’t need to go crazy with modifications to get some serious results. A good HD clutch, an exhaust to get them sounding how they should, and a safe, reliable tune makes a world of difference!

For all your dyno tuning needs, give Jarrod a call on 0431 412 380 or message the page to get booked in.

And if you’ve made it this far mention this post and you’ll get a discount on your tune for the first 1 weeks of November 💎

Stop leaving power on the table and get the most out of your diesel powered car.

Jacob’s xr8 turbo in to finally get the 98 side done on the pcmtec multi tune 😎 we did a muffler delete and fabbed up a side pipe for track days 😍

We kept boost around 12psi and managed to crack 411rwkw which is very stout for a 100% stock engine.

This combo is super super responsive with boost and Timing, and hopefully one day soon we can get Jacob to get this thing built so we can see what it really has to offer 😜🔥

None the less another car off the rollers and back with the customer.

Don’t forget to message the page for any tuning whether it’s stock ecu or haltech, diesel or petrol we have you covered 😎🙏

Here we have Angus’ Ford Maverick in the shop to finish off the fabrication work and get it ready for tuning.

Unfortunately, during first few dyno runs something wasnt right, we found cylinder 6 was down on compression, so rather than risk damaging the engine we’ve decided to hold off on the dyno tuning until the issue is sorted. That’s the gamble with second-hand engines sometimes.

The setup consists of a 6Boost T4 manifold, PSR G40 turbo, and boost control handled by a 50mm PSR wastegate.

Fabrication work carried out included:
✅ Custom 3” intercooler piping, powder coated black
✅ 4 inch lobster back intake
✅ 4 inch intake to suit airbox
✅ Custom 4” stainless dump pipe transitioning into 4” oval for clearance (was built to suit the 3 inch catback but it wasn’t up for his power goal)
✅ 4” exhaust system with a side exit (for now)
✅ 2” stainless wastegate plumbing with flex section incorporated to minimise stress and prevent cracking long-term
✅ Exhaust wrap to finish it off

Looking forward to seeing this one back once the engine issue is sorted so we can put it on the dyno and see what it can do 😎

Shoutout to Chris for always making me push this thing further than what it probably should go on 98 😅. We don't have easy access to E85 out here, and everyone reckons big power and pump fuel don't belong together on a Barra... but here you go 😎

This combo is one of Chris' 800hp packages that we've been fitting to plenty of cars lately. It consists of Spool rods, cast pistons, upgraded valve springs, ACL main and big-end bearings, Boundary pump gears and backing plate, along with the usual bolt-ons including a PSR Gen 3 3584, big free-flowing exhaust, 40NB 6-into-1 manifold, and the good old Kelford 218-B camshafts.

Once we got into the tuning, Chris' goal was simple — 30psi with absolutely no remorse 😂. In the end, I gave it everything I was comfortable with on 98 and landed at 28psi at 4000rpm, tapering to 24psi by 7000rpm.
We spent the day testing boost and timing combinations, doing around 30 dyno pulls, many of them back-to-back. The best result was 550rwkw and 1130Nm, with all the boost fed in by 4000rpm.

We knew we were well into the territory where things can go wrong quickly, but that's exactly why we wanted to test it. After plenty of monitoring, tuning via my own knock detection setup, and a final spark plug read that I'm happy with, this is where it landed 👌

My counter argument to anyone is to go and put 28psi into one @ 4000rpm and see what it does, it’s quite impressive

Hopefully in a few months we can revisit it with a G40 hanging off the side and see just how far we can really push it 😈

Keep your eyes peeled 👀

Well lookout we have finally acquired a new dyno!!! 😁😁

How exciting is that! It’s been a long time coming but I’ve finally made it happen and welcomed home my “new” dynotech chassis dyno, I couldn’t be happier. 😎

First off on the rollers was this 2022 2.4L Toyota hilux in for a remap, I’ve attached a photo of the before and after run with the torque and KW figures so you can see the gains yourself, this is definately a lot more responsive and better to drive for towing.

IF you have a diesel powered car/4x4, stop leaving power under the table and call us to get it booked in, tuned properly on a dyno and returned with decent gains around, it really is the best thing you can do for any modern 4x4 diesel vehicle the results speak for themselves, along with added power you will have better fuel economy aswell, so why wouldn’t you? Get in touch today and the JMC team can get you sorted. 💪🔥

Another JMCBUILT manifold to suit a Barra into an x series, cannot wait to see how this one sounds it has come up a treat

Hey crew hope everyone has had an absolute killer of a week like we have at the shop 😎

Just thought it is about time to do a bit of a post about the shop, I have been in here coming up to 2 years and I wouldn’t change anything that’s happened , but moving forward I am lifting my hourly rate for everything, this has been a huge problem in me actually being able to move upward and forwards.

My general rate is going to be $130/hour for all basics and diagnostics work etc.

My fabrication, elec and dyno rate is now going to $150/hour all including GST.

I personally guilt trip myself into feeling bad for people because of how much it has cost customers and then I always end up being the one that puts myself last in these situations, and for what? I should not feel sorry for someone that there race car costs them money, so does mine 🤣 and we still love it.

Unfortunately I have been my own worst enemy and NO ONE else is to blame but I will no longer be negotiable on anything. I have had to lower some of my standards on numerous small things to match budgets that should just be knocked back and I’m unfortunately not doing this anymore as this world is so toxic people will just blame my workmanship and not understand that the funds where not there so I am going to remove this completely.

I have included a few photos of some of the work that I have really enjoyed doing so have a bit of a look through and give me a like 🙏

And also, a huge thankyou to all of my loyal customers , I hope most of you can understand where I’m coming from and not have hate towards me , but if you do unfortunately there’s not much I can do I’m going to put my shop first 😎

I know that I put more effort into this then a lot of people and I have spent so much time getting to where I am it wasn’t just handed to me so on that, happy racing guys and keep it to the tracks 💪 I’m out

Recently I had baileys ba xr6 track car in for a handful of work , he bought this car and then realised it needed a lot of work we got a plan together and got it happening.

Started by fitting the following

✅crow cam valve springs

✅new genuine ford timing chain kit

✅intercooler kit built in house to suit the SC.

✅custom set of DUAL stepped 6 > 1 extractors customers request for F1 sound

✅ 3 inch extractor back exhaust

✅turbo smart big bubba BOV

✅ 2.75 inch pulley

✅ water methanol jet fitted to cooler piping.

I got it all finished and dialed in on the dyno, the cheaper intercooler was unfortunately dropping boost a lot as you can see via the dyno graph, red line is pre intercooler and the blue line is in the intake manifold so we unfortunately didn’t get the power we were after, but keen to see how it goes at the track and keen to see what we can do with intercooler later. The IATs were around 55 degrees before and now with the intercooler the highest I seen WOT on the dyno was 23 degrees.
