Not many engines better then an Rs Cosworth YB
This ones freshly rebuilt and is very big spec for an NA engine. Great torque curve and still making respectable power on twin weber carbs.
It’s already been fitted to the Mk1 es**rt as you will have seen in the last Youtube vid 🙌🏻

This video shows the different leagues of #FAST!! On the right is our Stripped out 600+HP Astra Gsi hitting the 8k rev limiter. and the camera car is my good friend’s 950+Hp Evo 9 with the beautiful straight cut gearbox whine! which was king of the streets at the time. For perspective i have a video of the Gsi sitting side by side to 180mph with a 800HP V10 Twin turbo RS6 so it shows just how ballistic the EVO was.

What better way to test the new cooling system overhaul then doing some test hits on the hottest day of the year? A few months ago this car was a mess but most of the issues are sorted now, now we can move on to setting up the chassis properly. This is only 27psi so plenty of room for more boost and race fuel 😈 On the left you can see a very nice stripped out Black Civic EF racecar that wanted to race but unfortunately never had enough Vtec..
