NZ Performance Car - - Construction Under -

No scene em­braces the con­struc­tion side of things more than mini-truck­ing, with the mini-truck guys rev­el­ling in the dis­play of half-com­plete projects that fea­ture off-the-chart lev­els of fab­ri­ca­tion awe­some­ness — it’s built into the cul­ture, re­ally.

Twelve-years deep into the build, Wiremu’s ’84 Mazda B2000 is a mix­ing of new and old school, which is show cased by the ’80s pin­stripe and fac­tory beige paint­work, with a set of late-model Hilux steel­ies in ox­ide red.

Un­der the bon­net there’s a Mazda 13B built by Cur­ran Brothers Rac­ing (CBR) us­ing all-new parts straight from Mazda and packs a 200-shot of ni­trous, elec­tronic fuel in­jec­tion (EFI), an elec­tronic ig­ni­tion with Bosch coils, a Mi­crotech LT-10c, and an S5 fivespeed with three-puk clutch. “I al­ways wanted fuel in­jec­tion — it had to be an old ute with late-model fea­tures, like EFI and air-ride,” Wiremu ex­plained. Stay­ing true to the blend, he de­cided against run­ning an un­der-dash pedal setup, choos­ing in­stead to ex­tend the fac­tory booster for­ward, sim­i­lar to what you would see in an old Ford, which al­lows clear­ance for the front wheels and wild in­jec­tion setup.

With burnouts on his mind, the ute will run on E85 to help keep things cool while on the pad, de­liv­ered via dual EFI Hard­ware throt­tle bod­ies with 1000cc in­jec­tors that sit atop a cus­tom man­i­fold. CBR has been tasked with tun­ing, with the fi­nal dyno tune and set up of the ni­trous yet to come — there are whis­pers of some ex­tra port­ing if the num­bers don’t match Wiremu’s ex­pec­ta­tions.

As sug­gested ear­lier, the crown jewel of the mod­ern mini-truck is the chas­sis work, and this ex­am­ple in­cludes a cus­tom C-notch with cus­tom airbag mounts to hold the Slam Spe­cial­ties RE-6 bags, fed by quar­ter-inch valves and lines with two Vi­air pumps and a sin­gle air tank — the front cross mem­ber has also been mod­i­fied. The rear diff is con­trolled by a cus­tom three-link, se­lected over a four-link to al­low the fac­tory fuel-tank lo­ca­tion to be used to stop the tray from be­ing over­taken by a fuel cell or air-ride gear.

The B2K has just un­der­taken a com­plete strip down, with ev­ery­thing to be pan­elled and painted, with the well­side join­ing the party — although it’s been ex­ten­sively mod­i­fied to fit the new notch and wheel height — which will hide all that lovely chas­sis work. Not to leave any stone un­turned, the in­te­rior will also be fresh­ened up, and the B1600 seat will re­ceive a re­uphol­ster.

Wiremu hopes to un­veil the ‘com­pleted’ truck at the 2017 V 4&Ro­tary Na­tion­als, so keep your eyes peeled for it. Hope­fully, it’ll also be swing­ing on the skid­pan that day.
