    RPW 1.6 Litre Stroker Kits coming soon

    We are in the process of building a autocross vehicle for a customer who we are building the first of our 1.6 stroker engines.

    We will be purchasing a spare motor so we can offer exchange short motors in the future. These are bored / stroked out to 1.65 litres (To be exact) and are the perfect engine size to reduce turbo lag, produce very broad torque improvements etc.

    This particular vehicle will be getting our hybrid TF035/TD04 turbo upgrade, camshafts, valve springs and lots of other goodies. The focus is not on peak horsepower, our aim is around 280hp at the wheels at peak, around 17 - 18 psi boost. Our focus is to keep turbo lag very low, but have torque from 2000rpm all the way to redline to make this a killer out of corners and make use of its power to weight ratio.

    We havn't finalised pricing yet but will let everyone know when we do.

    We will be providing exchange short motors for those wanting to do there own head work, or a complete motor package up to there budget level.

    I will update some more information once we finalise this particular motor build but it will be a very exciting vehicle to drive. I am qutie excited about it.

    We have another vehicle we are also building for the same type of racing, but that will stay with the 1.5 litre capacity, but with forged internals and our hybrid TF035 turbo package as well. Although this customer is considering the stroker motor as an option as well.

    So we may have been quiet over the last two years but plenty has been happening. The majority of it has been customers slowly building there vehicles up with our staged packages, and we are now seeing these customers transition into what I believe these colts are best for - autocross rockets.

    Photos and more news to follow soon

    The upgraded turbo and manifold package all look identical to stock. I did take some photos somewhere but will have to find them. We designed it from the start though to look factory and fit up with factory components so for the majority of people, they would look at it and not think it any different to factory.

    You can just purchase the stroker kit of pistons, conrods, bearings and crankshaft and do the rest yourself. Camshaft profiles vary according to what the customer wants.

    Are there any parts for sale if i would build a new engine myself? Or just full packages from rpw?

    Like a set of Crank, Conrods and Pistons for the 1.7 stroker. What profile are the camshafts?

    Your first post says 'photos and more news to follow'. Specifically I was hoping for some photos of the you describe at post #28. The installed turbo on the engine etc.

    Haltech won't be but we are making our own full plug and play solutions for the vehicle. But it will be with a Haltech Elite 2500 ecu

    Will haltech offer the ecu as plug in?

    Just waiting on an updated file from haltech so we can complete the installation and then run the vehicle up and tune. We are also building two other 4G15 stroker motors now for other customers. Working on another design as well - a 1.7 Litre engine block upgrade which will use parts from our stroker kit.

    The turbo is our hybrid TD04 turbo that is a direct fit to the stock manifold (Or in this case our steam pipe manifold) and utilises the stock wastegate actuator and turbo exhaust outlet. We tuned a a stock 1.5 engine block with this turbo at 240hp at the wheels so with a stock turbo intake housing so with this new turbo which has a larger inlet housing, stage 1 camshaft and stroker motor, 280hp - 300hp shoudl e easily achievable.

    Blake is racing his colt with like 260kw at the wheels, and has never had an issue with the gearbox fith ralliart LSD fitted.

    Also what turbo you running?

    And price on kit?

    There would be no issues with the gearbox, especially with the quaife ATB unit fitted. Gertrag boxes are strong by there very design.

    how do you think the stock gbox will go handling the increased load once engine is up and running full power?

    Our test vehicle is now up and running and performing nicely. We did a very crude break in tune on the vehicle and feeding the larger turbo into the stock airbox with the existing air intake restrictions and limited boost to only 9 psi the new engine is already producing 185hp at the wheels. No real cam timing done at this time as it would be too time consuming to waste time fine tuning with the stock ecu. The new Haltech Elite ECU is going to be used to create a full plug and play solution for the complete removal of the stock ecu, as the Elite has full drive by wire control. No more laggy throttle

    Once the Haltech elite is fitted, new air intake fitted and some real tuning done and this vehicle will be very impressive. Will be doing a full write up on our website with some photos but honestly, if you looked at the engine bay it looks nearly identical to a mildly modified Colt with normal mods. Boost curve so far is nearly identical to the stock turbo / stock engine setup which is exactly what we wanted.

    Best of all, the engine bay looks very stockish nothing looks like it doesn't belong there from the factory.

    Feel free to ask any questions on this you wish.
