The Engines
VW Golf - 1.8T
The little 1.8T is already a very good base with a closed deck cast iron block which has had plenty of development over the years, its strong and can handle power with guys overseas pushing 1000hp+ out of this application.
We built the engine following Integrated Engineering’s 700Hp engine recipe as this company has probably done more development on the 1.8T then anyone else in the world, however we have used a few parts from other companies to personalize the engine build to our taste and to make it suitable for track racing.
Block - AUM 06A 1.8T
Weisco Forged Pistons
IE Forged Rods
IE Block Girdle plate
BC Stage 2 camshafts
Ferrera Valve Springs and retainers
3 Angle valve cut
Balanced rotating assembly
All APR hardware

IE Manual cambelt tensioner kit
iAbed Baffled Sump
Grams intake Manifold with Grams 70mm Throttle body
Turbozentrum cast tubular Exhaust manifold
Borgwarner EFR6758 Turbocharger
While the engine is built to handle 700hp, performance target is a reliable 450-470Hp at the engine on 98 which is around 270-280kW estimated wheel which is what the turbo is rated for (450-500hp) and should be more than enough to put through the front wheels. We will also be building the fuel system for ethanol with flex fuel so an E85 tune using a Haltech Elite ECU will be in the works so we should hopefully be able to push this to 300kW wheel.
Honda Fit - K24 2.4L NA
While we said the 1.5L puts out decent power for its size, it just wasn’t cut it when going up against the 1.8 Turbo golf, especially from a cost point as the L15A engine hasn’t been developed enough in our mind to push a ton of power out of it, so a lot of parts would have to be custom designed. Instead, because these days with Honda’s its all about the K-swap, that’s exactly what we have done.
As JP is an expert with the K series engine platform, he already has a dyno proven all motor engine design that in a DC5 Integra made 200kW wheel on 98 and 230Kw wheel on E85 (which everyone mistakenly thought it was supercharged), the decision was to recreate this engine package but doing a few extra tweaks to improve on.
Block - K24A3
Increased compression ratio
Nippon Racing Forged Pistons
BC Forged Rods
BC Stage 2 cams
BC Valve springs and retainers
APR Head bolts
Type-R Oil pump conversion
Custom Head Porting
3 angle valve cut

Custom Ported ITR short runner intake manifold (To be upgraded to ITB’s later on)
JS Racing FN2 Headers
As the same with the 1.8T, the plan is to run this on both 98 and Ethanol using flex fuel on a Haltech Elite ECU, with a power goal of around 210-215kW wheel on 98 and 240-245kW on E85
