RT Posted September 23, 2012 Share Posted September 23, 2012 Ok so my capri was originally a manual, then I put a V8 with auto box in it and certified it. now I've changed it back to manual. No cutting anything to put change the auto to manual. I've heard that I can just pay for an adjustment to my cert plate rather than having to re-certify the whole thing?

cletus Posted September 23, 2012 Share Posted September 23, 2012 Trying to mount seats in my car. The 'reputable' aftermarket rails that i have bought are garbage and: A) sit too high won't let me sit far back enough in my car. If i eventually want to cert it anyway, can i make my own seat rails out of 3mm steel, in the same fashion as the brackets on my side mounted racetech seat? I'll be using the OEM mounting points in the car, but the rails will now just be made out of steel plate measuring approx 500mm x 60mm rather than the aftermarket ones i have with their bird shit welds. Car will most likely have an authority card by the time im ready to cert, so i'm not worrying about sliders at this stage (and it's a two seater anyway) if you have an authority card, the seats can be fixed, if not then the drivers one must be adjustable. you can make your own rails. are your belt buckles mounted off the seat frame?

I've heard that I can just pay for an adjustment to my cert plate rather than having to re-certify the whole thing? last time i asked lvvta if we could do that they said the only thing we can do a plate 'adjustment' for is a wheel size change. otherwise its a re cert. only have to look at whats been modified since last cert, so its not too hard, still expensive though seems to be the latest thing that cops and testing stations have been super tough on lately too, cars that dont match the cert plate 100%. had a guy the other day that was certed for 18'' wheels on a gtr skyline, put original wheels on to go to the drags and got pink stickerd for it.

Main issue was regarding home made seat rails. But as long as thats all good, should be able to make it work fine. Quote Link to comment Share on other sites More sharing options...
durty Posted September 26, 2012 Share Posted September 26, 2012 Random question If you got some Mad Sick Adjusties and wound them so they were captive and just above 100mm then welded the shit out of the adjustors so they were no longer adjustable would you still need cert?

cletus Posted September 26, 2012 Share Posted September 26, 2012 yes you would need cert Quote Link to comment Share on other sites More sharing options...

Seedy Al Posted September 28, 2012 Share Posted September 28, 2012 Can I use 5mm plate to make engine mounts? hearts Quote Link to comment Share on other sites More sharing options...
cletus Posted September 28, 2012 Share Posted September 28, 2012 of course you may. design of the mount bracket is just as important as what its made of . what is this for, your diesel van? Quote Link to comment Share on other sites More sharing options...
Seedy Al Posted September 28, 2012 Share Posted September 28, 2012 Na, 2jzge into Crown I dont think it will be to hard to do. haha Quote Link to comment Share on other sites More sharing options...
beachlander Posted September 28, 2012 Share Posted September 28, 2012 Just got a new car yesterday. Has a certed exhaust. At the moment it has twin tips after the muffler, however they angle up and have blacked out my bumper. If i chop the tips off and weld straight tips on, will i have to get it re-certed?

JoKer Posted September 28, 2012 Share Posted September 28, 2012 sounds like a noise level cert? or is it a LVVT cert same as adjusties etc? Quote Link to comment Share on other sites More sharing options...
cletus Posted September 29, 2012 Share Posted September 29, 2012 technically any mod after the cert voids it. where is the sticker stuck on? Quote Link to comment Share on other sites More sharing options...
mikey Posted September 29, 2012 Share Posted September 29, 2012 I've had to cut a section out of the stock crossmember to clear the front of the engine I'm swapping in. The crossmember no longer is used to support the engine. I was going to box this up with 3mm plate is that legit? The original steel is around 1.5mm thick. Stitch weld or continuous? Also what dimensions should I make the trans mount plates I weld to the floor? Stitch weld sweet? Thanks cletus; legend. Quote Link to comment Share on other sites More sharing options...
beachlander Posted September 29, 2012 Share Posted September 29, 2012 Sticker here, which is why i thought i could get away with it as its before the bend And why i want to change it Quote Link to comment Share on other sites More sharing options...
TTONEFOURTWO Posted September 30, 2012 Share Posted September 30, 2012 Question: Is it legal to swap an S14 silvia crossmember into my corona to use the silvia engine mounts etc. The one thing that needs modifying is the holes which go through the chassis rails are 130mm apart and the factory ones are 80mm apart (aprox). Can I just drill the new holes in the chassis rails and bolt through as normal? I realise this will have to be certed. Thanks! Quote Link to comment Share on other sites More sharing options...
KKtrips Posted September 30, 2012 Share Posted September 30, 2012 You will need to drill the holes and put crush tubes in too.. Quote Link to comment Share on other sites More sharing options...
TTONEFOURTWO Posted September 30, 2012 Share Posted September 30, 2012 So with crush tubes welded in it will be sweet? Might be easier to just change the engine mounts. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted September 30, 2012 Share Posted September 30, 2012 It was an observation of fact what you would need rather than a big tick from the cert side.. I'll let Clint confirm that side though. Chances are you would need to see what you are proposing to confirm it. Also is the suspension or steering tied into the crossmember? There would be a lot more science going in to that than just swapping it if that was the case.. Quote Link to comment Share on other sites More sharing options...
cletus Posted September 30, 2012 Share Posted September 30, 2012 good chance it would be a LOT easier to make new mounts. in theory you could use a complete silvia crossmember/rack/struts/brakes. it would be a fair bit of work both in mounting it all correctly and setting it up. potentially a lot better handling and braking if done right.
