***THESE ARE BUILT TO ORDER due to high demand average 5 week build time after recieving a paid order, all orders are non-refundable once paid***

After a ton of hard work we are proud to release the new BA/BF BOSS kits. These are our most complete kits to date and come with everything except fuel system and tune. Over 30hrs labour goes into fabricating each kit on intricate jigs! Rated at 400rwkw its amazing how easily these motors make power with boost.
They drive amazingly and sound like nothing else. Our work ute made 416kw@11psi on 98 with a completely stock motor.

We are offering these kits with a 70mm turbo 


The kit requires NO chopping/bashing of the cars inner guards/lights or battery tray and is as bolt on as can be. A fitting guide will be included but only someone competent should attempt installation.


Priced at $6484.50 + GST plus postage. Everything in the kit is backed by a 12months warranty. 

We can cater for drive in drive out conversions too from 13K inc GST. We have recently had a customers BA go 523rwkw with a built motor and the 70mm turbo on e85. ​


Due to fraudulent false chargebacks costing us thousands we have been forced to remove credit card/PayPal from our payment options. EFT bank transfers only. We appreciate you understanding.
