Swedbricks' 360 Rallycross project - 'Gebakje'

Did you manage to sort new nuts for the GAZ front inserts.
On the clutch/flywheel is there a good option available https://www.classicswede.org/shop/360-turbo-flywheel-conversion-kit-with-clutch-240mm

Yes I contacted GAZ directly and they were able to set me up. Do you have 27mm sway bars in stock still? Looking to do some further work with PU on the suspension eventually, I also emailed you I believe

I have a good few of the 27mm anti roll bars in. Might be worth resending that email. Make sure it is to dai@classicswede.co.uk

Decided to get some more track worthy belts and deep dish wheel

And some budget friendly steel framed buckets for now

Got to stripping out the shell after fitting the wheel

Cut the cage I got into bits and started piecing together a half cage from the remainders

The rear shock towers will get tied in, and I might add an additional cross support and front bars to reinforce the main hoop

Next up stripping the sound deadening

Got a air hammer as a tip from Borrie, with my shed being at freezing temperatures, no need for dry ice

The front seat mounts came with M6 retainers and wouldn't be adaptable to the new M8 seat rails, so those got removed along with the sound deadening.

In the process I uncovered some rust in the wheel wells, and at every jacking point. Nothing that will be hard to fix however.

In total the interior came in at 100kg, with an additional 26kg of sound deadening for the part that I didn't vacuum out, getting the car to an approximate 900kg. I'm aiming for 750-800kg, such that I'll be able to be competitive in the semipro class with around 200hp allowing me to keep the car N/A.

FYI I just used a bunch of WD40 and a wirewheel to get the remaining residue off.

Thanks, I've been using thinner and a rag which works but slow, so I'll give that a try as well!

Got some bathroom scales:

It appears I'll have to do some thinking on where I can drop more weight, underlined are weighted, the rest is an educated guess

 

[classicswede]

Clutch and flywheel you can save around 7kg converting to the flat flywheel.
Glass is heavy and big saving to be had changing to plexiglass

 

[Swedbrick]

That should help, I checked the side windows already, which were 20kg combined, with the rear that would be 10+kg in saving. The front is required to be glass by regulations.

As for the engine, a header and going with itb's and a small alternator and underdrive pulley will also help a bit hopefully icm the flywheel. It's all in the front so a double win. 25kg would be pushing it though.

Iirc you've adapted 200sx coilovers in the past right? The front struts weight 16kg each, and setting the rear up with coilovers and a 4 link should also cut some weight.

Getting it to sub 900kg would require more cutting and carbon however, so adding a turbo might be more economical. The kg8 camshaft claims up to 240hp, but I'm not sure I'm willing to spend on an 8v to get it there without power adders

So with the interior stripped, time to start on the driveline given I'll wait for the weather to improve before doing the welding/painting

Got the transaxle in, which was quite a process, given the bellhousing didn't fit through the tunnel. Got it in the end though

The transmission brace requires these M10 bolts, which on my 340 chassis were not present, so some cutting was needed

Whilst under there I also got the old seatbelt mounts removed for the future 360 gas tank conversion

Got the engine in, also quite difficult, not a 2/7/9-series for sure, space is really tight, and I forgot to drop the subframe. I might just drop the entire drivetrain next time.

Given the engine was still on blocks, I looked towards the stock 360 engine mounts, which are hanging strangely. No straight lines exist on the framerails, and normally theaded holes would get a plate to the rubber mounts from the top.

Decided I hated this design, grabbed a set of old 740 mount with diesel rubbers. The old subframe already had mounts, so I moved those to work.

I also found this threaded hole nearby for a m10 retainer, so I added an additional brace. The frame was pretty rusted, so welding was pretty awful.

Pretty confident the new setup will work, and I have more space for activities now under the intake, which is nice. I can also switch to defender mounts and shim the engine around a bit if needed as well now. 360 mounts are NLA, so all good things

With the engine in place, time for some induction. Printed up these PLA prototype adapters, ordered fillamentum AF80 for the final print along with the lockpad, hopefully that will fare better than my previous Vinyl 303 attempt on the pcv system which cracked due to thermal expansion.

Got the GSXR 750 throttles mounted

Finally welded up the throttle shaft

Made backets for the fuel rail as well and painted it all

All mounted up, throttle cable bits are still underway. I'll modify the original to suit, given I have one with the end broken off

For those wondering, both fuel rail and filters are tight, but it just fits

Also got a new tool!
