The BMW E46 V10 sequential gearbox conversion has reached the next stage as I begin the install. The DCT came out without too many dramas and as soon as I've finalised a few details, the flywheel and clutch can go away for balancing, the driveshaft design and production can begin and I can look into how I'm going to make the rear crossmember and plumb the oil cooler. The exhaust that is currently on the car is definitely not up to the task of making the most of the engine performance or most importantly the sound that the V10 should be making at 8000rpm. Hopefully I can talk the owner into letting me sort that out. 😁

Just posted my latest You Tube video. Have a gander and let me know how crap it is. Looking forward to some of your "feedback" 😁

I hear that you want to convert a BMW S85 V10 to work with a Quaife QBE69G six speed sequential gearbox. Good choice! You've come to the right place. These videos show the parts that I've made to do just that. Bellhousing, block to bellhousing billet CNC adapter, flywheel, clutch etc. If you want to see more follow the YouTube link below to see me run through the entire process. Thanks. Kerry.

Last week I finished the cage in my customer's BMW E92 M3 trackday car. TIG welded, chrome moly 8-point cage attached to the shell wherever I could to create the stiffest and safest structure possible without using any more tube than neccessary. Because it's road legal I kept the side intrusion bars quite low to make it easier to get in and out of when it's being driven on the street.

1x Main hoop - done. 2x A-pillar bars - done. Now to install the rest of the jungle gym.

The most important and difficult tubes in any rollcage in my opinion are the main hoop and a-pillar bars. If I don't get these dead right I'll pay the price in time and presentation for the rest of the job. I have to keep thinking ahead to how the rest of the cage will come together so I can finish the job happy that it is the best cage I can put into this car to suit the customer's requirements. I'm very happy with how they've turned out. They fit really tight against the car so I can attach to multiple points later on and I've tucked the a-pillar bars as high and wide as I can to give as much clearance as possible to the driver's head. Anyway, plenty to carry on with. More updates to come.

I usually say no to anyone asking me to fab a roll cage now, I've done more than enough over the years, but occasionally I'll say yes as long as it's something interesting. I'll happily put a road legal track day E92 BMW M3 into the "interesting" categorie. It's going to have an extensive chrome moly rollcage attaching to the chassis and body wherever I can and will all be TIG welded. I'm on the Motorsport New Zealand Recognised Manufacturers list which means MSNZ have seen plenty of my roll cages over the years and like what they've seen. The customer wants to have the stock dash back in it when I'm finished which adds a little complexity in terms of exactly where to run some of the tubes but shouldn't be a big deal. Pulling the dash and all of the electronics out, and then back in again on the other hand will be a drama. The job involves more than just a cage though. I've already installed a lightweight flywheel and twin plate clutch and have also completed a full air-con delete, a bigger job than it sounds. Removing the AC pump, heat exchanger and all of the plumbing involves pulling half of the engine bay apart to gain access to everything. That's all done now, time to start throwing the tube on the floor next to the car atsee what it looks like at the end. There's a cheeky little easter egg in the corner of one of the images. BMW V10+six speed sequential dog box+E46=😁Stay tuned peeps.

First time on track after a very long, ground up build for a customer's Alfa Romeo GTAm restomod.
