JC 13b Star­let

NZ Performance Car - - 4 & Rotary Nationals 2017 -

Long-time read­ers will re­call Andy’s KP Star­let ap­pear­ing on the pages of NZ Per­for­mance Car back in 2006 (Is­sue No. 119). At the time, it packed a 5K set-up for cir­cuit rac­ing, but it saw lit­tle track use be­fore the power bug bit. Af­ter a friend con­vinced him to do a ro­tary con­ver­sion, all things pis­ton re­lated were sold, and, within days, Andy was the proud new owner of a JC block.

All the fab work to marry the two to­gether was car­ried out by Chris at CageFX, and the stock en­gine was set up us­ing a stock Se­ries 5 turbo, which made 190kW at the wheels and ran a PB of 12.7s be­fore de­vel­op­ing a gearbox is­sue. While the box was out for re­pairs, Chris ac­quired and strapped on a GT35R, then slapped it all back on the dyno. Un­for­tu­nately, that combo “was hit with dyno-itis and the en­gine blew up” ac­cord­ing to Andy. Once the pain had less­ened, another JC block was sourced, and, as he was crew­ing for the Dat­a­logit FC RX-7 drag rac­ing team, Steve and Alice of­fered to strip the new en­gine to check its health and make sure it was go­ing to be OK with the big­ger turbo. Of course, this was when some­one sug­gested that if it were ever go­ing to be ported, it should be then. In fact, most of the parts used are iden­ti­cal to those used in the FC, so it’s geared up to hold some se­ri­ous power, and the driv­e­train suits, run­ning an FD RX-7 five-speed backed by an XC Fal­con drive­shaft and Hilux LSD. Jacky from Jtune was en­listed to get things run­ning right, and the combo now makes a re­spectable 225kW on 9psi. It’s also helped Andy lower his PB to 12.3s at 128mph (206kph).
