Or was it just blocking airflow? I'd just let it block that top section of the intercooler, it will probably still do some cooling in that section.

It blocks the top 120mm of cooler and is a big square tube... quite annoying Quote Link to comment Share on other sites More sharing options...
RXFORD Posted March 30 Share Posted March 30 Is an Gtr style intercooler an option? Shorter but quite wide. Instead of having the outlets of the end of the tanks, have them exit back toward engine. Or just run a smaller one so you don't have to change piping but have a water/meth setup as backup? Quote Link to comment Share on other sites More sharing options...

I might just go small less problems, this cooler came as part of the Tony's Turbo Garage kit i bought and chopped up. Can save this setup for non road events.

Jeffs_Emporium Posted April 3 Share Posted April 3 Wanting to IRS convert a low spec (solid rear) 80s toyota mark ii/chaser/cresta. They have the same floor pan and I have taken the braces between chassis rails and outer sills for the subframe pickup points from an IRS parts car. Is this a straight forward swap with regards to cert if using factory parts? 57071/2 are the braces i kept still attached to section of chassis rail and outer sill for correct placement while im here do i convert rear to take an s13 rear coilover (beef up trailing arm pickup and put strut towers in rear) 1 Quote Link to comment Share on other sites More sharing options...
cletus Posted April 3 Share Posted April 3 i cant see a problem with that if its all factory parts, and the work is done well, welding is good, sealed and painted etc 1 Quote Link to comment Share on other sites More sharing options...
Metalhead96 Posted April 4 Share Posted April 4 Dunno if its come up before but i read on the lvv fb page that someone said that guard rolling is no longer legal in regards to wof? Reason being that it "structually affects the vehicle body" and thus is now a cert issue? Quote Link to comment Share on other sites More sharing options...
ul9601 Posted April 4 Share Posted April 4 semi-related, how much of the guard has to cover over the tyre/wheel for it to be legal. most guards are widest at the top and tapers in down at sill level? Quote Link to comment Share on other sites More sharing options...

Measured from top of arch as far as I know. Won't be many arches that don't curve inward. This part of the PDF covers bolt on flares, but if if you just have unmodified body, then measure the same way and should be good. I'm sure Clint will confirm yeah / nah. https://www.lvvta.org.nz/documents/infosheets/LVVTA_Info_05-2020_Tyre_Track_Protrusion.pdf this one shows factory body better vs tyre tread, only shows front/back profile with top of arch used as reference https://vehicleinspection.nzta.govt.nz/virms/in-service-wof-and-cof/general/tyres,-wheels-and-hubs/tyres-and-wheels#tab2 3 hours ago, Metalhead96 said: Dunno if its come up before but i read on the lvv fb page that someone said that guard rolling is no longer legal in regards to wof?

Front guards for example tend to just bolt on, so I can't see how they would link that to being structural. That said, people will probably ruin guard rolling too, by taking the piss and they will have to bring in rules. Had to flare mine to get enough clearance through full suspension travel for my cert. Didn't even come up as a mention when I explained how I got the clearance. Double skin in rear of mine so fold it over doesn't really change much. Front couldn't do much as bolt on single skin so weak as fuck arch. 4 Quote Link to comment Share on other sites More sharing options...
Popular Post cletus Posted April 5 Popular Post Share Posted April 5 Modification threshold specifies guard rolling as not needing cert.

kp60nick Posted April 9 Share Posted April 9 Question regarding plating chassis rails for welded in tube crossmembers. I made a cardboard template of what I wanted the plate to look like but once I made it and bent in 90⁰ it lost length and no longer spans the whole height of the rail. Is this a problem should I remake plate? Picture for better explanation. Quote Link to comment Share on other sites More sharing options...
Adoom Posted April 10 Share Posted April 10 Do I recall something about proximity of things like fuel line, battery cable and brake line to the propshaft when routing under the car? Or does it not matter where I run them as long as it's secure, not going to hit the ground and can't touch things that move or spin? Quote Link to comment Share on other sites More sharing options...

I had to fit a driveshaft hoop to the diff end on mine as the fuel line could’ve been taken out by a damaged driveshaft if the rear uj let go. my fuel line had to run along the side of the tunnel Quote Link to comment Share on other sites More sharing options...

Probably fine, by the time there's a weld there it will be pretty much at the bottom 1 1 Quote Link to comment Share on other sites More sharing options...

I usually recommend running them away from the driveshaft where possible, as a rear loop on a solid axle car is (a) hard (b) looks stupid (c) not particularly effective Not quite as bad on something with IRS Quote Link to comment Share on other sites More sharing options...

The driveshaft hoop will be something like the red scribble. The sides of the tunnel and front seat area has two 'floors' with a cavity for some reason so I was planning on bringing the hoop mounts forward to the chassis box section. 3 Quote Link to comment Share on other sites More sharing options...
