The versatility of this product is incredible! We knocked up some intercooler water lines, and a set of valve cover breather for a tough streeter yesterday,

All symmetrical, all run into 90 degree bulkheads in the rail, flush and fresh! Can’t wait to see them on!

We make hoses and lines for all applications, street and strip, race and cruisers! Brake, oil, water and fuel, we have the solution for you!

After a few broken weeks due to commitments in Darwin, we are back full swing delivering to our customers! Motors, plumbing, all round repairs!

We’ve got a heap of plumbing to get done, a few wingless motors to finalise and send off, and some new builds to spec!

We are also now stocking Wix Racing 51060R filters, we use these on our personal and built LS engines, as well as the most popular applications for open midget and sprintcar motors!

Get in contact today if there is a way JM23 can help your program!

Hump day Plumbing! Got this wingless kit knocked up for one of the best in the business, prime minister Egan.

This is all you need right here for a current spec wingless car,
3 x -8 water lines
Power steering suction
Power steering pressure
Fuel in and out.

Tailored for the 47 specific, but you get the idea!

John trusted us with the majority of his off season build, and anyone who knows that car, it’s easily the pinnacle of the class!

We sell brand new Genuine Siemens injectors to all our wingless customers, but we also clean, service, flow and flush your current or spare sets of injectors!

Don’t get caught out this season with a dirty, poor set of injectors jammed in the back of the toolbox! Send them to us for a service before the new season

We also service all types of injectors, not just limited to wingless applications

You don’t want them to look like this!!

It’s been a busy busy 6 weeks here trying to get everyone’s motors serviced, repaired and built for the coming season, LS and wingless!

We also do a lot of street and strip engines and hose maintenance as well, so we are a very very time poor shop!

This is a quick one for wingless guys who don’t like to CRC or WD40 their engines after use, just do it, please. It will thank you for it. Methonal is a very dry and harsh fuel, with little to no lubrication, marry that with your 7 year old paper air filter that lets in 40 cubic tonne of dirt per race, and you’ve got yourself an hour glass bore, a rusty cylinder head and a set of seats with 40% leak down.

Use the WD40, life gives ya nothing, use it

Sundays are normally for rest, wasn’t the case for us this week! Got a heap of plumbing done, ready to head out the door this week for a great customer of ours!

Clean, sleek black/gold combo and some wing ram/valve hoses to finish off!

Off season is in full swing, let us know if you need any BMRS plumbing for your program.
Brake, fuel, oil and water lines all done in house!

We’ve been quiet on socials lately, as you could imagine with off season in full swing, guys are getting their programs updated and freshened, resulting in a very busy schedule! This week has been LS nation, we have 6 in the shop at the moment! Small repairs, big changes and a bit of R&D!

Had a ct525 we did a freshen on, small changes and a few tricks, on the dyno yesterday to get run in and some very impressive numbers! Had another getting some head repairs and some valves replaced, as well as a spring and retainer package to maximise valve train stability!

A big couple weeks coming up with more motors being dropped off, more cars needing plumbing, and more dyno!
