BLG Engineering

A few in-between jobs completed recently.

◾️ Coilover and wilwood setup for a MK2 Es**rt.

◾️ 626 tune along with port matching manifolds, rewire of the dizzy/coils and other small tidy up work netting a nice 184hp at 9300rpm from the unknown history 12a bridgeport.

◾️ full 3” exhaust for a skyline along with a 38mm plumb back wastegate and removable section, promuff muffler in raw finish and 4” tip.

Another job complete and another happy customer, we had the job of designing, fabricating and fitting these tool box’s to a flat deck ute. Filling in the gaps and being practical we think they look pretty good and will do the job perfect. 👌👌

Couple jobs completed this week, a pair of Rx3 Coilovers and a Large radiator been sent out, along with another cooling system fabricated and fitted on the Rx2 we are currently building.

Another shortened and built hilux diff complete and ready to be sent to Auckland. This one was fabricated to bolt straight into a 323 hatch and utilises our wilwood rear brake setup, a built and shimmed L*D head, splined axles, mounts and brake lines to suit. 👌👌

Josh dropped his little hatch in for some fab work, we completed one of our full cooling systems consisting of a triple pass radiator, 80mm thick oil cooler, 100mm thick intercooler, EWP and AST. We also fabricated our new designed exhaust manifold housing the new SXE363 and 60mm turbosmart wastegate, 3” intercooler piping with plazmaman clamps and turbosmart BOV, along with a few other cool little touches.
Josh is planning to finish some of the basic plumbing and assembly then drop it back for a fuel setup, wiring and tune.
Look forward to seeing this little beast on the dyno 💪🏻

We have just finished up the exhaust on Karls stock car, running tuned length runners, one of our designed collectors, and our new prototype re-packable race promuff muffler allowing it to be run as a muffler, straight pipe or repacked if needed. The new combo sounds amazing nice and deep with no horrible cackle like some others.
Next we will put it on the dyno to see the gains with the fresh motor and new exhaust setup 💪🏻💪🏻

A little job in the engineering bay we completed for the local Tree Nursery, we were tasked with designing and fabricating a dirt mound that attached to the front of their polythene roller.
We designed the mound to be fully adjustable in height, width, angle and three point linkage adjustable. It was put straight into operation and is working perfect. 👌

Here it is, after man hours together as a team we managed to pull our R&D motor down, inspect and change all internals, changing from Batty rotors to High Compression RX8 rotors that have been extra lightened and balanced, Clearanced Crank, Oil Mods, New Stat Gears and Bearings.
We assembled with no other changes to see a true back to back test from 9.0 compression to 10.0 compression.

A day on our dyno we gathered data on the engine, and to our surprise there is no gains in the rotating assembly, however we are down 10hp across the complete rev range with the only noticeable variation is the engine compression differs, possibly due to sealing and RX8 type side seals, or limited run in time of the new seals.

We completed many runs changing timing, timing splits, increased rpm limit to 11,000RPM, with no gains and consistent runs of 315hp

This engine uses 46mm D ports, RX8 Rotors, All new Mazda seals, One of our 58mm intake setups, tuned length and matched exhaust, One of our high flow mufflers, Haltech Elite 1500 ecu, EGT Sensors, Wide Band Sensor, Oil Temp and Pressure, Fuel Temp and Pressure, Coolant Temp and Pressure, we also fitted a Vacuum sensor to the Throttle Body for testing purposes.
Haltech IGN-1A coils, IC-7 Dash.

With this information we can now use this to support our customers decisions, with our next testing will be port size and timing using the same engine base.
👍👍👍

Playing catch up on jobs over in the engineering bay, we have finished this aluminium gate with rollers and track for a local customer. 👌

40 Silage bales - Flynn’s Fundraiser | Trade Me Marketplace This Auction is for a unit load of 40 bales of silage, all bales were donated by farmers around our amazing district to be auctioned off to fundraise money for ...

Our Engineering side had a busy few days completing some much needed repairs to this old conveyor, we had to remove the hopper and belt, replace all the rollers, brackets and adjusters. Also fabricate a new main guide roller with new bearings along with adding some strength back into the rusted main frame.
This should keep the old girl turning for a few more years…… 😂

We have had Shauns RB25 180sx in for a heap of fab work, wiring, first startup and tune. Completing the intercooler piping, catch cans, dump pipe with external gates, under car surge tank, adding in a DBW setup, all plumbing, sorted and finish wiring, sensors and dash along with a heap more work we completed the first start up and break in tune only to find a few issues with voltage and ignition supply. We fitted a new 140amp alternator kit, VR38 coils with Hayden and myself tuning we managed a nice safe 268kw on 17psi. 👌👌
Shauns project has been a work in progress for a few years, he decided to drop it off all to be completed in house and can now drive it out (minus a few panels 😂)

Couple more small jobs ticked off this week.
1.) Another set of our front coilovers using our camber/caster tops, these are heading off to be fitted into a Rx2

2.) Finished up the oil catch can and Radiator over flow tank for Haydens Rx2. Catch can using our flush breather style and Mazda logo cover plate.

3.) A new oil cooler for our Rx2 as the old one was overdue for replacement and was our prototype for rear mounting them with fans mounted.
Now using our new cores we have seen a decrease in oil temps on the road and the rear mount setup works perfect.

Mitchs DX was back in for a facelift. We just finished up converting the square front to the twin round front end. Some will know this isn’t a straight forward swap over. But how cool does it look now 💪🏻💪🏻

Epic time with Billy Hol Charlie Stanaway misfiRE
Dyno runs, skids, and sharing all the stuff we do here. 👌👌👌

We finished up this 13” brake kit, coilovers and shortened hilux diff for a 323 wagon. This is the first time we have setup our wilwood 4 pot rear brakes with mechanical handbrake to tuck in behind a 13” wheel, this took some extreme fitment testing and machine work to get correct. Now to be sent off so the customer can fit it all into there 323 as a direct bolt it setup.

Patricks Capella went straight through certification and is now all Legal, we received great feed back from LVVTA in regards to our work and car setup involving the engine, driveline mounts and setup, diff install with chromoly rose jointed 4 link, our coilovers and wilwood brake setup, full exhaust and in house mufflers meeting noise requirements and many other parts of this epic rotary conversion making this a true drive in drive out build.

We are super excited to finally release our own injection throttle body setup, this has been in design and testing for almost 12 months now, most testing has been done on a flow bench with numerous different styles, designs, and injector positioning, we have finally created a setup that has the most power gain and movement of air. A challenge was to have single piece shafts, due to thermal expansion we seen the blades always changing causing inconsistent returning and changing idles.
We can supply these in 56mm 58mm and 60mm bore sizes. Incorporated is 4 x injector ports and prevision for sensors, NOS ports or vacuum port.
Another feature we wanted to offer is the changeable length velocity stacks, these can be simply set to long or trimmed to have short depending on your setup or tuning capability’s.
These are a direct bolt on to the IDA manifolds and we will soon to be offering with a IDA style k&n filter setup, along with a full Haltech ecu package to make a simple plug and play injection upgrade.

Here is another of our radiators, this one is for Nigels rx7, we also had a tricky task of fabricating a radiator shroud and brackets to support the fans been used. Cant wait to see this installed and his car back on the dyno 👍👍

Its been a busy couple months, but we managed to finish Mitch’s little DX over the weekend. It came in running a stock 12a with a sidedraft carb setup and a poor working fuel setup, after pulling down the engine we carried out a nice street bridgeport, all new genuine mazda seals, new bearings, clearanced crank, new exhaust, fuel tank and setup, 48mm EMPI carb, one of our Rad/Oil Cooler setups, new wiring and a heap of other bits to make this a reliable streetable car.
After running the engine in on the dyno we managed to get a solid 221hp from the little 12a Bridgeport, a nice achievement that our setup is working well 💪🏻💪🏻

Eddie dropped his JZX100 in for some fab work, we fabricated a intercooler to fit in around the factory a/c, intercooler piping that required no cutting of the car to fit, modified a supplied exhaust manifold, 3.5” dump pipe and half section of the exhaust, twin 38mm wastegates with plump back pipes, fitted the new precision turbo along with a few other small jobs.

We finished fabricating and fitted this aluminium dog box for a Ranger. Twin dog compartments, tool boxs with lids and a tie down rack on top. It fitted perfect and locks down onto the wellside using a adjustable turn buckle setup. This will look even better once its been powder coated black.
