DD700 Package 700+bhp



Our DD700 package is designed to give a reliable and effective 700-730bhp, depending on specification, by strengthening the engine’s internals with forged pistons and con-rods, replacing the original turbo and manifold with our own big turbo kit, improving the fuel system, fitting uprated cams, valvetrain, porting the head and offering a complete Syvecs ECU replacement.

The price is for a drive-in, drive-out package and includes all labour, fitting and mapping.



Our price is based upon the car being healthy and already having a suitable intercooler. Some intercoolers on the market do not flow well enough to make the power.



What our a few of our customers have to say their DD700 packages:

“I heard about Devil Developments and the new ECU they was using called Syvecs. Syvecs helps get the power down for a much better drive and is packed with features. However, my turbo was running out of steam, so Lee suggested fitting a Precision 6466 turbo, Nortech tubular manifold and 60mm wastegate. Along with a ported and flowed head, bigger valves, forged engine and Airtec Stage 3 we are currently seeing over 800+bhp at 1.9bar, or 798bhp on a hub dyno at 1.7bar. The car drives perfect, no lag, reliable and boy does it go. I can’t thank Lee and the lads at Devils enough. I wish I could turn the clock back and go straight for this conversion. Unfortunately it’s taken me 4/5years to get the car to the power I been after, along with folders and folders of bills costing over £50,000. Is there more to come, you ask from the guys at Devils. Hell Yer!”
