Toyota Supra MKIV build

This customer first came to DI Racing back in 2014 after his car underwent some questionable work by a ‘reputable’ Supra specialist in the UK. Upon inspection we found many loose AN fittings, missing nuts & bolts, exposed wiring and an overall lack of quality workmanship. We quickly fixed his problems for him by installing a Precision 6266 turbocharger along with other modifications. The customer came back at a later date due to worn turbo seals which had occured due to a lack of oil, so once again another single turbo conversion was underway – this time a bigger, badder Borg Warner S366 straight from BoostLabs in the USA. The car currently runs a comfortable 600bhp @ 3400rpm for street use. Here is the full spec list:
