Diff 1.5 or 2 way. Use crown wheel & pinion gearing suited to the particular engine you're going to run

Tyres

Radiator + air guides

Brake pads/fluid/lines + overhaul calipers

Clutch + braided line. Lightweight flywheel.

Adjustable suspension links front + rear

Coilovers front + rear

Pay to have someone setup your suspension properly if you don't know how / want to get running sooner

ROPS

Seat + harness

In-car camera for use as a review/training aid

Spend time running it like that and learn to drive with stock power level for a season or two. Add up the costs above, IMO those are the things required for reliable, safe track running. If this is your first track car, you do not want/need 300rwkw. Plenty of fun to be had <150rwkw

Personally I would be doing these:

- The usual mods (exhaust, intercooler, pod or panel filter (your choice).

- Oil cooler

- Good tune

- Coil overs

- Sway bars

- Strut brace

- Decent tyres

- Brakes (rotors, pads, oils, braided lines etc)

Do a track day with these mods and then see how you are going.

Suspension, brakes, seat/s, harness/s, tyres, oil cooler, a real catch can, ROPS, replace all bushes, 1.5, full service on all the oils and fluids, to start with.

Dont overboost it and dont run it on the limiter

Is it going on a trailer or stay regoed ?

Remove all unneeded fat, carpet, deadener, A/C, trims.

Is the car stock or modified ?

Money to burn ? carbon everything, full strip rebuild, aero, dash, flashing lights and bells and also whistles, see the superlap site for details

i have an R32 - which im thinking of turning into a track car.

what mods / work would you recommend? (dream big guys and gals - would rather do it right and spend extra $$ than have a half arsed effort)

thanks

Look at existing 32s that are going fast at the local track here ie. sub 1:15 kind of lap times - and learn from them.

Dont build a christmas tree, they are rarely fast.

bugger all that! do what i'm doing and chuck an ls1 in your 32.

much cheaper, lighter, just as powerful and you can be a trend setter, not a follower.

besides that how much fun can you have with instant torque?

    • Thanks for that, I'll check it all out. I can always do the brakes last anyway if its a problem.  The 16's are super cool, if they do fit I'll cruise around with them for a bit.  
    • Well, that's kinda the point. The calipers might interfere with the inside of the barrels 16" rims are only about 14" inside the barrels, which is ~350mm, and 334mm rotors only leave about 8mm outboard for the caliper before you get to 350, And.... that;s not gunna be enough. If the rims have a larger ID than that, you might sneak it in. I'd be putting a measuring stick inside the wheel and eyeballing the extra required for the caliper outboard of the rotor before committing to bolting it all on.
    • OK, so again it has been a bit of a break but it was around researching what had been done since I didn't have access to Neil's records and not everything is obvious without pulling stuff apart. Happily the guy who assembled the engine had kept reasonable records, so we now know the final spec is: Bottom end: Standard block and crank Ross 86.5mm forgies, 9:1 compression Spool forged rods Standard main bolts Oil pump Spool billet gears in standard housing Aeroflow extended and baffled sump Head Freshly rebuilt standard head with new 80lb valve springs Mild porting/port match Head oil feed restrictor VCT disabled Tighe 805C reground cams (255 duration, 8.93 lift)  Adjustable cam gears on inlet/exhaust Standard head bolts, gasket not confirmed but assumed MLS External 555cc Nismo injectors Z32 AFM Bosch 023 Intank fuel pump Garret 2871 (factory housings and manifold) Hypertune FFP plenum with standard throttle   Time to book in a trip to Unigroup
    • I forgot about my shiny new plates!
    • Well, apparently they do fit, however this wont be a problem if not because the car will be stationary while i do the suspension work. I was just going to use the 16's to roll the old girl around if I needed to. I just need to get the E90 back on the road first. Yes! I'm a believer! 🙌 So, I contacted them because the site kinda sucks and I was really confused about what I'd need. They put together a package for me and because I was spraying all the seat surfaces and not doing spot fixes I decided not to send them a headrest to colour match, I just used their colour on file (and it was spot on).  I got some heavy duty cleaner, 1L of colour, a small bottle of dye hardener and a small bottle of the dye top coat. I also got a spray gun as I needed a larger nozzle than the gun I had and it was only $40 extra. From memory the total was ~$450 ish. Its not cheap but the result is awesome. They did add repair bits and pieces to the quote originally and the cost came down significantly when I said I didn't need any repair products. I did it over a weekend. The only issues I had were my own; I forgot to mix the hardener into the dye two coats but I had enough dye for 2 more coats with the hardener. I also just used up all the dye because why not and i rushed the last coat which gave me some runs. Thankfully the runs are under the headrests. The gun pattern wasn't great, very round and would have been better if it was a line. It made it a little tricky to get consistent coverage and I think having done the extra coats probably helped conceal any coverage issues. I contacted them again a few months later so I could get our X5 done (who the f**k thought white leather was a good idea for a family car?!) and they said they had some training to do in Sydney and I could get a reduced rate on the leather fix in the X5 if I let them demo their product on our car. So I agreed. When I took Bec in the E39 to pick it up, I showed them the job I'd done in my car and they were all (students included) really impressed. Note that they said the runs I created could be fixed easily at the time with a brush or an air compressor gun. So, now with the two cars done I can absolutely recommend Colourlock.  I'll take pics of both interiors and create a new thread.
