Hey guys, i have read the other rollcage thread but it didnt help me. I already have a 4 point cage but need the front half done as I plan to go a bit faster than I origionally thought. I plan to run low 9's high 8's in a vl calais using a 26/30. Im trying to do as much work as i can myself as Im a plumbing apprentice so funds are quite limited! I thought the best way would be to be buy the front half kit in chromoly from Mcdonald brothers racing as i cant bend anything myself. The problem is I didnt get the rear 4 point off them so dont know how its going to match up.

1) Is this the best way to go about it?

2) How do i notch the pipe when butting up to the existing rear cage? What tools will I need?

3) What welder can i use to tack it together before i get someone to weld it properly? I have an oxy? Would that be suitable just to tack it? What filler rod?

Thanks

1) probably not the best project with out all the tools but if u do than fine

2) pipe notcher or in you case a grinder , die grinder and a program i this section called tubemiter

3) tig with moly filler and oxy to heat "cherry red"

cheers

also depends on what tube your going for, im pretty sure you can use seemless steel, but with a thicker wall .. you need to read your rule book - im guessing ANDRA - to get exactly what materials you need.. and to ensure what you already have is still usable.

if u plan on anything under 9.99 theres a mininum 6 point full weldin roll cage chromoly is usally material of choice as its lighter than mild steel and aluminum is a no no

but check andra rule book for your time bracket (et) and make sure its the new version as rules to cages changed about 2 year ago

The back half is bolt in and I want the front half bolt in aswell. I know it will be hard but it can be done. I will be racing at calder and they are fine with bolt in cages. Im a bit pissed off that its not up to andra specs though as Ive already paid 1700 just for the rear. Its not up 2 spec in 2 areas - it is bolt in, and the rear 2 points mount to the top of the wheel arch.

      Would be good in your car I reckon Johnny. Have seen reports they don't seem to love circuit use and sustained high RPM, but there's so many variables and implementations it's hard to tell fact from fiction.  All that said, is it worth it in this car given how you feel about it? Probs not?

      R34 GTR Front Diffuser/Guard Liner questions.

      By Duncan · Posted

      I don't know specifically. I *do* know that it is very likely that historically most/all undertray replacements remove the inner liners and people just run without them. When you are hectic (or serious) enough to really want/need a different undertray, you are probably also running wider, taller or different offset wheels and the guard liners are the first thing that rub (or as I said in the other thread, they blow out at high speeds anyway) Of course, that is before the pricing went nuts on R34s, nowdays it is much more likely people want/expect to retain the liners to protect their overall investment

      Haven’t had a chance to drive it properly yet. It was rwd and pissing down rain when I drove it home and now it’s in the air with the so I can change the oil. Going to do the  gearbox oil while I’m at it as well, may even do the diffs

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      On 12th June, the mechanic could not figure out what the issue was, but the car seems to be flooding with fuel. He was suspecting the tune, thus referred me to a tuner. Although the tuner is not familiar with Nistune, last Monday (30th June), he came over to try and re-map it. Despite the tuner trying to completely stop fuel, it kept sounding like it was pushing fuel. Tuner ended up suspecting either the ECU or Injectors. I do not believe the ECU or Nistune is the issue, as the Nistune software reads and communicates properly. Today, I removed the (new) injectors to see if they are clogged or leaking. Surprisingly enough, after those 3 days of driving, injectors 2 and 3 look very blocked. You can see the difference in the picture. I blew a bit on 3, that is why it doesn't look as clogged as 2. I am still unsure if this is what is causing the no start issue, but I am now feeling that I may have bought the injectors and Nistune without the need to do so, as the problem seems to be coming from somewhere else.
