NZ Performance Car - - Inside Line -

One of New Zealand’s long­est-serv­ing im­port drag cars, the Mazs­port FC RX-7, has seen a few dif­fer­ent en­gine com­bi­na­tions over the years, but none as se­ri­ous as what now sits un­der the bon­net. The car has un­der­gone a ma­jor rebuild over the off sea­son, as owner Brian Con­nell put to­gether a new 20B block us­ing a Tur­bosmart cen­tre plate and new-de­sign Pre­ci­sion En­gi­neer­ing three-piece crank. The oil­ing and cool­ing sys­tems have also been re­worked, along with a full re­wire to com­bat the charg­ing is­sue the car suf­fered last sea­son. But it’s the turbo that’s the crazy bit, it’s a 98mm GEN2 Pro Mod item, the lat­est tech­nol­ogy avail­able from Pre­ci­sion in the USA, and a unit that driver and tuner Tony Markov­ina had sit­ting at home.

To give you an idea of this turbo’s ca­pa­bil­ity, the 20B made 611kW (819hp) at the wheels with next to no boost. Tony told NZPC, “The car can make as much grunt as any­one else can, but it’s an old chas­sis and just can’t com­pete. We are ba­si­cally us­ing it as a test bed for a fu­ture project, aim­ing to get some re­li­a­bil­ity,” This car is a piece of im­port drag-rac­ing his­tory, so the team wants to keep it that way, which is also why he has re­fit­ted a stock RX-7 dash and re­verted to the old livery . But that’s not to say they aren’t hop­ing to bet­ter the cur­rent 7.84 at 286kph PB.
