    Fuck those DSS axles. The two ends have identical splines and look identical but one snap ring groove is slightly deeper than the other. Can't really see it unless you measure it- which is about 10 mins after you started trying to bash fuck out of it into the custom CVs fucking. Actually you may not have that problem- stock CVs?

    Yeah I just reused the stock CVs, the hub and CV upgrade was another US$1500. They'll now be the weakest point but I think I'll be fine with the power I have and not being for drag racing, I've got a spare pair of axles if I do a CV.

    Cheers. The race season starts in 6 weeks time so I'll be pushing as hard as I can to make the first event. I give myself 25% chance at this stage though...

    So with the sports sedans class, hows that work with putting a totally different engine into your car? No rules around what you can do manufacturer wise/etc, but you just race in a class based on capacity?

    Sports sedans are the most open category of touring cars in the country, and pretty much the longest running category. Essentially the cars must be front (or front/mid) engined & retain the silhouette of the car. Typically space framed with bespoke suspension and front/mid SBC Chev or Nascar motor. There are minimum weights based on capacity, aero rules and the cars can have a complete carbon/glass body.

    Yeah as Guido said there's a lot of scope within Sports Sedans, mine isn't close to the level of a state or national car. At the local level where I compete they don't get pedantic about the finer points of the regs so long as it's safe and in the general spirit of that category. My previous SR20 S14 was in Sports Sedans because it was just outside the requirements for Improved Production.

    Pretty much finished the fuel system. I couldn't find a fuel cell at a reasonable budget that I felt prevented slosh and kept the fuel around the pickup. I don't want to worry about foam breaking down and having had pumps fail, before I wanted to keep things as simple, reliable and lightweight as possible, so no surge tank and second pump.

    As posted earlier I designed and cut my own tank from 2mm ally which I then had welded. It incorporates baffles, return tube to the bottom of the cell and fuel level sender (ended up slightly different to this image, with the horizontal baffle on the other side of the fuel return).



    Sender & lid are attached with closed end rivnuts and I laser cut some gaskets to suit



    Magnafuel 74 micron bulkhead pre-filter, Protuner 525 external pump, 25 micron post-filter and regulator.


    Returnless system runs a single AN8 through the cabin with bulkhead fittings under the rear seat and front firewall using Fragola pushlock hoses.



    And done!

    Keep an eye on the magnafuel pump and inspect it once in a while. No idea why but quite a few people i know have them and rebuild them due to issues. Also see a lot for sale. You have quality pre and post filters, which probably is most of the issues

    Looks very nice. Where are you getting the Fragola fittings?

    Nice work. Are you still aiming to race early this year?
    Logical debate beats name calling any day. My Badges Of Honour so far in PF: Racist, Bigot, Islamaphobe, Numpty, Moron, Far Right Wing Nationalist, Far Fight Wing Fascist, "raving fucking lunatic", "dumb" & climate "denier". AND they are just SOME of the pathetic tags that I've been labelled by SOME here. HINT: Those labels are signs that the accusers have lost to logical debate.

    Maybe it's time for them to check some facts. Here's a good starting point: http://www.mostdamagingwikileaks.com

    I spent weeks researching fuel pumps and had a hard time deciding between Aeromotive, Bosch, Holley, Fuelab, Weldon and Magnafuel. It's not hard to find negative reviews on any of them but the Magnafuel rated well so I went with it. Perhaps I should hook up fuel pressure monitoring on my Haltech.

    All from Summit. I tried to consider every bend and length then ordered exactly what I'd need a few months ago. Almost got everything right. I didn't want to use China fittings and Speedflow were just too much for my budget.

    Yes hopefully I can start testing everything in March. There's just so many potential hiccups when everything on the car is new and untested.

    Oh yeah, lot of bad feedback on everything. You might be fine, as I said just keep an eye out

    The car has been at Classic Auto Electrical for the past few weeks and I picked it up yesterday. It was free of all stock wiring except for brake light plugs so he created a basic body loom (pressure activated brake lights, front bumper lights, wipers), installed my Elite 2500, modified the Elite LS1 loom to suit and bent up a tray for my little Lithium battery. I had a Deutsch kit from a PF group buy and various other switches, Bussman boxes, DTP plugs, plug mounts, etc that I'd bought for my previous S14, but there was still another few hundred in parts required. I'd probably just like to remake the switch panel in my own style, otherwise everything is very nicely done with twisted wires, thoughtfully routed, easy to access and disassemble.





    I had grand plans of fitting lots of parts over the weekend and this week but unfortunately as I was finishing unloading it off the trailer I herniated a disc in my back which dropped me to the ground and at the moment I'm basically an invalid. Once I can get moving again the next few steps for the car are to have an intake pipe made and a bit of a steering column relocation, then remove the engine again to have someone partially disassemble and check over it as I don't have confidence in the original builder who shafted me. The first event for my series that was meant to be in March has been cancelled due to the resurfacing of Morgan Park running well behind, so that has given me an extra 2 months or so.
