so how do you drive backwards in the rain phil, sounds kinda dangerou

Whoa.... talk about off track thread!

This is about getting a 33 GTS-t to 900kg guys, lets be serious can we.....

I think you'll need to use GTR front guards.

just remove the guards altogether , not like they are doing anyting useful

Thanks for all the replies . I have read them all. Interesting and helpfull. The car has been stripped of interior parts and has no seats or carpets, sound insultion taken out. Have the sprint v seat ready to go in with harnesses. The air con will be removed next. I am considering putting a carbon fiber bonnet on after the air con removal. I believe these can save approx 8 - 9 kg. after that will remove sound deadening from boot, few extra interior parts to go. BTW how much will the air con on an R33 weigh? how much weight would aluminium radiator save?

Took the aircon out of my 32 the other day, everything in the engine bay came to 14.9kg.

Aluminium radiator weighs a similar amount to the standard plastic one, how ever the larger size means it will take more coolant and thus increase the overall weight.

i saved around 8kg in doing the rear quarter and windows lexan. thats in a 31 though.

if its track only how about

fuel cell

removing hicas +all lines

titanium nut/bolts +wheel nuts

rotor with alloy hats

bonnet boot and doors in carbon

smallest wheels your brake will allow (i think you save around 1kg a tyre a inch)

alloy/titanium pipe work

etc etc

maybe even going something like a LS1/X/2 or VQ35DE+t lot of weight saved in alloy blocks and ive seen a dude pick up the 6 speed out of the VQ35 under one arm!

depend on how serious you are i suppose.

does the R33 have the same plastic fuel tank in between the spare tyre well and the rear seat the same as the s14/s15? If so fuel cells difference can not be as great and where i have seen most people place them is higher in the centre of gravity.

As I see it, the front of gtst's is where most issues are in terms of easy weight to remove.

frp bonnet and guards are a no brainer. I have made an mould and pulled a set of Kevlar guards out, <1kg each. Front bar with splitter is still in the works.

Eliminate all the normal comfort stuff, sounds like you have done most of that.

The windows, reg etc in the doors saves 20 kg on its own. Trimming the extra fat off the steel door ends up lighter than carbon ones I have weighed.

I have seen an s14/15 strut front end in a 33. I question if the weight of a loaded car will flex the strut, but I am looking into this over the next week.

I think close to 1000kg is realistic and possible, that's where I'm aiming, I'm building it for 2A Sports which has a min wieght restriction. I'll be under so this way I can choose where it goes to balance it all up nicely on the scales.

Photos of front bar? :)

Also while on this topic, does any one actually know the weight distribution of Skyline models? (As in 60/40, 55/45 etc).

Has any one weighed one properly? How much weight from the front has to be removed (or moved to the rear) to bring out a better balance towards 50/50? (obviously would be very hard for a GTR with the extra weight over the front axles).

2nd pic from the top shows it. This is not suitable for a street car, it sits way too low.

Theres another pic further down that shows just how far the splitter protrudes.

track car only.

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
