We're getting closer and closer!

Production is underway and over the next couple of months we'll be sharing more info about the tensioner design and testing as we get closer.

Price and ETA will be shared towards the end of May.

We're busy bees in the background trying to get these ready ASAP so bear with us and hold tight a couple more weeks until we're able to share more info.

Here's 2 spicy red heads to start your week!🔥🌶️

These two 698s are going out this week both destined for BAs.

This isn't any 1000hp. This is a properly optimised package to give you a wide power and without sacrifice.

Most customers opt for stage 4 cams with their 698 to allow them to retain VCT and really maximise the high velocity ports on the 698 heads. Even though we've improved flow significantly with these heads, we prioritised velocity to increase the engines efficiency and therefore torque across the RPM range.

To chat 698 or other engine packages have a browse of our range and contact us

How's that for first start!

POV, you've just been born and identify as an Atomic 698 GTA. You've been primed with fresh zinc rich mineral oil, fresh copper plugs and a filter to get rid of all that engine placenta or whatever.

You're alive but not quite awake. A nearby Haltech gets the signal and gives you the kick you need to fire up for the first time. A quick check of pressures before we hold your RPM up high to get you warm.

You find your feet and after a few hours and several tests, you're ready to finish being run in in your new home (probably a muddy patrol or something).

By now we've recorded your ring gaps, bearing clearances, compressions hot and cold. We've tabled your oil pressure and confirmed your vitals look good! One day we might have to remeasure you and compare your stats to see how you've grown.

Maybe you'll go on to win red light GPs, chop your owner's mates at roll racing, and maybe even jump the light one day at a big race.

All we know is we've put a lot of effort in to make sure your life is trouble free and if you have any major issues in the first year, we'll fix you right up. When the RBs try to bully you, don't slip on their oily blowby, when the 2jz tease you, remember that the small dogs bark loud but don't bite hard. Show them what you're made of 💪

Go make boost, shoot flames, and slap limiter (respectfully)! Please don't come back unless you want more power, but send us photos and videos of yourself having fun.

All the best,
xoxo Team Atomic
