Default More paint restoration!

I took a while to look back and decided to get rid of the marks left from the sticker bombing (which got clearcoated)


So I kept on going deciding to also blend in the old repairs, starting with the A-pillar repair


And the repaired window section, 1500 grit -> motip spot blender -> 3000 grit, turns out old clear coat is much harder than the single stage but I think it turned out okay overall




The other side after this treatement


Couldn't wait do did the blended parts, so I gave them a quick polish, lookin good


With the holiday's finally here, I decided to go surfing (at a safe distance)

It was luckily pretty quiet


Last week was spent polishing the rest, pretty happy with the results, it won't ever
be perfect but this should do after some wax



I also finally updated the landing page for the sake of the new ones, since it was as old as the thread Rebuild on the xc90 calipers coming up!

Default camber and freshenup

To get prepped for the install of the new brakes the tapped struts to receive the adapter bracket received a rebuild, and the new yellow koni's


Starting with the removal of the totally destroyed dust shields (custom aluminium ones will be made in the future)


After which the steering arms got a delete, since the txr roll steer kit removes them entirely from the equation


Continued with scraping of the rubber coating and some sandblasting to get them prepped and ready for paint


I also made this little tool to torque the strut tops, two old hex bolts, 5mm plate and a file did the trick



With the struts themselves sorted, I moved to deal with the annoying issue of the txr plates shifting which I solved by welding them into place (I chose 50% ackerman to try as they adjust from full parallel to full ackerman)


I found out later that the new bolts supplied with the kit are grade 10.9 compared to the stock 8.8 and are tightened to 105Nm with some locktite for good measure, which explains part of the problem Also bought and freshened up this lot for the new setup:


And fixed my previous camber modding sins by using the drill press and measurement this time around


I used the original front studs from the old plates which seemed better quality and pulled in better than the aftermarket replacements, as I stripped the other set trying to pull them in to the drilled holes, whereas the volvo ones went straight in


Pretty content with the result!



I also got around to testing some prototype valve setting tools I made or myself and my brother


Installed the rear distributor delete plug


And got the plate I got lasercut to keep it there installed as well



The upgrades made a big difference, the car feels much more stable now, the 50% ackerman was a bit strange at first, but in high speed corners the added grip when pushing is definitely noticeable. With the new lsd rear axle in the works, it should also be better in low speed corners, with less front end push making the ackerman change noticeable due to the locker

A week after the holidays I swapped out the aussie locker axle for an open diff 3.54 from a low milage diesel, selling off the other axle to a friendly driftkid


With the funds I bought this 'Racing Diffs LSD conversion kit', it was a bit of a pain to install, but seems to work and it's a whole lot smoother than the aussie, it should be good for around 25% continous lock and is said to be able to reach 50% under heavy loads. We'll see if it lives long term, and does well on track.


I also got a set of 235/45r17 Vredenstein Ultrac rear and 225/45r17 front for the new wheels and mounted them by hand with a friend in under an hour, much better than the usual motorcycle tires


The rear wheels were now slightly rubbing, so I decided to sacrifice my rear wheel arches with a little cut and bash (gently)


Weirdly enough the car now appears to need more low, we'll work on that, since the circumference is still the same so good enough for now I guess


Whilst modifying the rear fenders, I discovered some of the previous owners 'repairs' so I'll have to get the welder out, whilst recoating the arches after the bashing


My Chinese intercooler piping also arrived, and it appears all should fit with one extra coupler to adapt the 13c to the 2.5 inch piping

I also got all the calipers together and the cast iron bits stripped down for the xc90 brake conversion.


The sandblasting cabinet got them perfectly clean ready for a coat of midnight black epoxy paint


The rear calipers got a full rebuild and the booster a strip and paint with rustconverting primer


I used the silver permatex grease on all the machined area's which got left bare during the painting process


The rebuild calipers with their stainless braided lines came out really nice


I also took the master cylinder apart to check the seals and give everything a fresh coat of brake fluid compatible grease for the new install


I also took the time to get my crack free manifold sandblasted and coated in heat resistant paint

So I finally got the front calipers installed, they stop incredibly well, the new booster is also a very welcome upgrade with a more progressive pedal response


I started with the removal of the old calipers


And realized after bolting on the new stuff the lines had to slightly be altered to work, so I modified the brackets for the brake lines and the lines themselves for the single piston setup, with the normal triangle crossover since I have the old 2x3 port brake divider


First time using this tool, it took some learning, but I managed okay with making the new lines from the removed second ones for the front setup


The braided brakeline was a little short, but I made it work okay, this being at full droop, without binding


The rear brakelines are a bit longer and will follow the trailing arms to get new connections under the sills


I also revised my rear break setup for the n-th time, to something I'm finally content with


Which has the working e-brake from the xc90 and an easily serviced caliper adapted to the axle retaining cap bolts, for which the steel version should arrive somewhere next week

Thanks! I'm pretty happy I found them, they were previously owned by a drifter, but the guys at the garage where I got them balanced were amazed at how straight they were. They're a bit heavy, but really solid so that's a good thing

Have you tried the LSD on track yet? Very curious about it.

Not yet, on b roads it's been well behaved, you only really feel it when the back starts to step out like it should. I might get it on a track in November, there's a session at Assen circuit planned

The steel for the rear brakes arrived a few weeks ago


I added some welds to the parking brake stoppers


Got all of it fit up to check if it was correct, managed to not break a single tap whilst creating the m10 threads, although the stress in the steel was noticable


Got started on the aluminium dust shields (2mm thick sheet)


These turned out pretty good, just need to make a tool to roll the edge, I have some bearings and 3d printer v-wheels so a solution should be easily made. I'll just have to now make the attachment for the brake shoes and get them sandblasted tonight ready for paint


The front dust shields have also been made to approximate size, I'm just waiting to finish my 3d printer enclosure to be able to create certain parts in abs without warping of the material, to create the original seal surrounding the hub's bearing

A few weeks ago I sold off my second intercooler and tubing kit and exchanged it for all of the silicon hoses I'll be needing for the turbo engine, only the cooling silicone left to go.


With the new wheels a spare had to also be sourced, so I got one of these 17 inch v60r spares on the advise of Lankku.


I also got around to sandblasting and welding up the last bits for the rear brakes, so the parking brake was now part of the assembly


With a very warm autumn day, I got onto the process of bolting it all on, and hoping I got my tolerances right


Starting with the parking brake cable replacement for the correct type for my new setup, which required this little ziptie trick to get the pin into place


I was in luck and everything received a bit of love from the torque wrench and loctite. The aluminium dust shields required a few changes so those will follow soon


For the rear brake lines I mirrored the original design from the fuel tank side, and connected it up after a new connection was added to the copper line. New brackets will be installed as soon as I receive my rivet nut tool

I'm currently running the oem pads on the calipers, as the size of rotors should keep heat to a minimal and bite is decent. I'll be looking at printing airducts from the fog light splitter I have laying around to add some cooling, and might invest in EBC pads and rotors as they are available, but only if the oem's start to fade

Finally march again, so I got the car back from storage, and immediately put it on the dyno with a fresh tune I worked out at home during the winter. Great thanks for klr142 for providing his mappings, they helped a lot in getting it worked out!

I switched to more appropriate 218cc ev6 injectors off my brothers second b6304, and burned a chip for a e-fan enabled tune to work with the 984 casing I had laying around. I ended up making 135whp at 190Nm, which suprised me greatly, pretty stoked on this last hurray for the N/A engine of this chassis. It will be sold off, or end up in another project eventually



Dyno plot below, without lambda unfortunately, as we couldn't get it to work with the volvo S shaped exhaust tip, which I will change soon. Pretty nice and smooth exept for the start around 2000 rpm, possibly an issue with idle/temperature enrichment and the high overlap of the K-cam. I might slightly modify that still, as wel as raise base idle rpm a bit to 8-900, but all in all the tune starts and idles nice, and is well behaved.


To repeat a small summary of the setup for reference:
10.3:1 b230k with stock 530 head
kg004 aka k camshaft
buchka wasted spark
218cc ev6 injectors
bigger J-pipe with turbo exhaust system
Chipped lh2.4 (own tune)

Default The fixlist

In anticipation of what it coming for the car, I got myself a turbo gauge with a Dave Barton front, ready for boost


The car itself received a thorough cleanup after storage, and I decided to get it back to classy, by getting rid of the stickers, and cleaning up the look by doing an antenna delete


Next up fix the 50% ackermann and put it back to 100% where it belongs with the stiffer sidewall


If you run these, clamp and weld in place to avoid movement, and torque to the specified spec for the stonger bolts they come with. Volvo spec will make these go loose on you due to the difference in bolt grade!


I also use the winter to make up these ezk chipping boards, which do not interfere with the chips already on the ezk like those of others. A few demo's are out, and after a solid bit of testing, I'll start selling them to those interested.


Next up, longer brake lines for the xc90 conversion, and a little shuffle of the brakelines. I now moved to RR, FF split on the junction block, as that felt safer. I put the front of the junction block to the rear brakes as I read that the bores on that end are smaller. My ABS booster has equal pistons sizes, so that should now result in the correct bias. From testing the system, it appears to be correct now.


Whilst bleeding the system, I also got to installing my KL racing braided clutch line, as the stock line was slightly expanding under the sachs racing cover plate. I even had enough dot 5.1 left to bleed both of my mountainbikes, rad

Default Turbo time

From my engine building thread, I finally finished the turbo engine, ditching the twin turbo's for a single 13c for now, with a custom 18t for the future after run in


It left my room in all its glory after 2 years


And received some vaseline loving to get the automatic transmission support bushing out


I made a little wooden jig to get the whiteblock internal, redblock external m90 transmission rear flange of to get to the seal and replaced it


The shifter seal also got refreshed


Along with all other seals


The lever balljoint also got replaced as well as its counterpart and shimmed by 4mm for the dogdish flywheel I'm using


Old engine came out, as did the old trans, heading for slovakia after a re-seal to Simon, along with all other goodies for his turbo project


The flywheel and clutch look mint still, given the trashing it receives, pretty good for a little sandblast flywheel cleanup before install


P.O. of my m90 internals hit the front of the splines where the pilot rides with a hammer as it appears, so I spent an hour carefully getting it back to spec with a diamond file


The new engine received the usual coolant bypass at the back of the head, to save the heater core, and to make the back of the head run cooler, due to the blocked port that used to go to the carb manifold in early b230's


And it's in


Only two casualties, due to me having to take the engine out twice past the grill retainers, with the crane not being on it's longest setting and the head hitting my expensive wasted spark ignition module, due to me not removing it like an idiot



I quickly put in oil, cranked it without spark until it made pressure shown by the banjo on top of the turbo, and used the old NA tune for now, with the NA intake to get a first start going. In short, it lives!


Next up, get the air filter, maf and intercooler tubing made up




On the to do list:
- {Chip my spare 984 and 148 ecu's and transfer buchka spark}
- {Extend maf wiring}
- re-tighten crank pulley bolt
- Mount intercooler properly
- Make new intake support braket and 2x2 coil bracket (now fits on back of head with defender engine mounts)
- Fresh fluid in trans (old one used for storage)
- Adapt exhaust and get that deal sorted
- Put in coolant, bleed system, shim power steering pump forward
- Run it in to temperature then retorque headbolts, put in T cam \w reshim, flip camcover plug.
- 50 km accel/decel run in
- fresh oil and filter (15w40)
- 500 km run in period
- fresh oil and filter (15w40)
- Add boost, hit dyno, zandvoort circuit
