Stu Jones’ ‘4AGTE’ Star­let

NZ Performance Car - - 4 & Rotary Nationals 2017 -

Stu has owned a de­cent hand­ful of EP71 Star­lets over the years, pack­ing a range of the en­gine it­er­a­tions of­fered — 2E, 2ET, 4E-FTE, 5E-FHE, 5E-FHTE, etc. — and you could say that he has be­come some­what of a knowl­edge re­cep­ta­cle for all things Star­let. The ex­am­ple fea­tured here was pur­chased as a low-kilo­me­tre white Si with the in­ten­tion of fit­ting a 5E turbo en­gine. Then, as all good plans are hatched, when shar­ing a few brews — in this case with Glen Becker, who built one of the first big-power 4A-GTEpow­ered KP60s in the coun­try — it was de­cided to throw a 4A-GE into an EP71.

The ini­tial build took a few years due to “bud­get con­straints / slack­ness / booz­ing / work”, said Stu, but would even­tu­ally cul­mi­nate in an AW11 big-port 4A-GZE run­ning a T04E turbo, a Link G1, and a gag­gle of other bits. The street tune made 195kW on 16psi and man­aged to run 13.01s at 123mph (198kph) on street tyres on an un­prepped track. Be­ing a slap-to­gether build, the en­gine took a beat­ing and even­tu­ally gave out af­ter los­ing oil pres­sure at Pukekohe. Its re­place­ment, which took some years to get sorted, con­sisted of a 20-valve­based en­gine fea­tur­ing a new in­let and exhaust man­i­fold, the “orig­i­nal an­cient” T04E turbo, a TiAL wastegate, and a new Link G4+. That combo ran the car into the 13.10s but had a few trig­ger­ing is­sues and blew the TRD LSD. Stu opted to switch the turbo out for a Gar­rett GT2876R and V-band hous­ing, which runs at just over 17psi and has set a PB of 12.1s at 113mph (182kph). The tim­ing re­mains con­ser­va­tive, and Stu hopes that, with a bit more tun­ing, it will run into the 11s on the same boost on a prepped track, with the New Zealand fron­twheel-drive Star­let record in his sights — 11.75s — set by close friend Kris many years ago be­fore re­tir­ing the car.
