pulse Posted July 22, 2003 Share Posted July 22, 2003 Hi all, I'm probably going to get shot down in flames but.. I have a (basically) stock jspec RZ auto. With a budget in mind, what would be the cheapest and easiest way to remove ~a second or so off the 0-60 time? If you have any ideas about prices, I'd like to know that too. Would it void my JIC warranty? I'm assuming others from here have the warranty from there, I don't know if it allows for modifications.. And if any of the traders on here would like to quote directly for the job, please pm or email me. Thanks! -p Link to comment Share on other sites More sharing options...
eyefi Posted July 22, 2003 Share Posted July 22, 2003 use powerbrake launch technique, thats pretty cheap Link to comment Share on other sites More sharing options...
Scooter Posted July 22, 2003 Share Posted July 22, 2003 one sec off 0-60mph........i don't think this is possible for reasonable money. There is less than 1sec between a standard tt and moderately modded tt over 1/4 mile (eg my old standard tt 13.875 Matt H's old auto just under 13 secs), so shaving a sec from the 0-60 is gonna be tough i would think. Doubt ( but am prepared to be proven wrong) that leon's, christians etc would be a sec quicker over 0-60 Link to comment Share on other sites More sharing options...
pulse Posted July 22, 2003 Author Share Posted July 22, 2003 Hrm. A friend is telling me that by fitting a cold air intake and a new exhaust from the dump pipe to the tip, increase the boost to the max. possible without changing the intercooler would do it fairly cheaply. I don't know what he knows about Supras, and I know I know nothing What do others think? -p Link to comment Share on other sites More sharing options...
outatime Posted July 22, 2003 Share Posted July 22, 2003 What about a 'Max Power' AND a 'Fast Car' sticker? Should put you in the low 4's... I dont think knocking a second off 0-60 is possible without major spending and some drag radials. RLTC will help get the power down and a lot of practice launching would be an idea. The Supra doesnt really find its feet until 40+mph, so 0-60 is not really a good reflection of its performance. Link to comment Share on other sites More sharing options...
Willson Posted July 22, 2003 Share Posted July 22, 2003 BPU + race gas and what eyefi said should help. And reducing weight, ie. stereo, interior, air con etc........ Otherwise get your credit card out And you'd have to ask JIC, they are helpful though. Link to comment Share on other sites More sharing options...
Faye Posted July 22, 2003 Share Posted July 22, 2003 I've got a JIC warrenty and when I asked about mods and what it would do to the warrenty they said that any mods wouldn't be covered but standard parts would be. Best checking with them though ( as I didn't go into what happens when a non standard part causes a standard part to fail ) Link to comment Share on other sites More sharing options...
Scooter Posted July 22, 2003 Share Posted July 22, 2003 There are cheap 'BPU' (search) mods that will give very noticeable improvements in the cars performance if increased power is your goal, but not improving other areas concerning fueling and cooling i.e. making do with a poor IC (not saying yours is but it could be) etc can lead to engine meltdown (literally). There are some nasty examples of the potential problems on the site. I would advise searching and reading as many threads as possible. Possibly helpful 'Keywords' Boost gauge, boost controller, restrictor rings, fuel cut, decat, high stall, fuel pump Link to comment Share on other sites More sharing options...
Guest Martin F Posted July 22, 2003 Share Posted July 22, 2003 Originally posted by outatime and a lot of practice launching would be an idea. That will always be the best bang for buck in improving your 0 - 60 times. Link to comment Share on other sites More sharing options...
pulse Posted July 22, 2003 Author Share Posted July 22, 2003 Hrm, you mean I'm going to have to learn to drive?! Dammit Cheers for all your thoughts I figured it probably wasn't possible to do cheaply (or I'm sure more people at the meet last weekend would've modded their car), but hey - worth a shot My main reasoning for wanting to do it is not so I can actually increase my 0-60 times, I don't intend on racing.. but a friend of mine has a TVR Griffith 500 HC, and I'd like to feel some of the raw 'oomph' you feel out of that when I put my foot down in the Supra Granted, though, the Griff 500's 0-60 times would slaughter a stock Supra's (it's 3.68s on the one I'm referring to, having been modded a bit) Btw, I was thinking roughly 1000-1500 pounds to do this, figured I could get a good few bits replaced with that. Ho hum. Thanks -p Link to comment Share on other sites More sharing options...
Guest Martin F Posted July 22, 2003 Share Posted July 22, 2003 Originally posted by pulse Hrm, you mean I'm going to have to learn to drive?! Dammit Please don't think i was being totally sarcastic (unusual i know!) with my response. It's well known that the weakest link in any car tends to be the driver rather than it's technical performance. This is more so on a track, but even on the strip practice will help immensely. Also we all know that launching the Supra to the best of it's capability is no easy task. Link to comment Share on other sites More sharing options...
pulse Posted July 22, 2003 Author Share Posted July 22, 2003 Originally posted by Martin F Please don't think i was being totally sarcastic (unusual i know!) with my response. Oh, not at all I know I'm not a drag strip driver, I am better at speed manouvering rather than just flooring it from a green light. I've never really tried drag racing, I enjoy nice driving more than just accelerating as fast as I can. By the same token, I was kind of hoping if there was something I could do to strip a second off the 0-60 time, it would be of benefit in the 70-120 margin too (ie, overtaking) Ho hum cheers -p Link to comment Share on other sites More sharing options...

Guest Terry S Posted July 22, 2003 Share Posted July 22, 2003 I doubt any of the big power cars are that much quicker than stock to 60 purely due to traction. Link to comment Share on other sites More sharing options...
Paul Posted July 22, 2003 Share Posted July 22, 2003 Originally posted by pulse what would be the cheapest and easiest way to remove ~a second or so off the 0-60 time? Drive it off a Cliff ?? ok, I'll shut up Paul Link to comment Share on other sites More sharing options...
AJI Posted July 22, 2003 Share Posted July 22, 2003 Bleed valve for about £50, FCD for about £70.... that should get you on your way. Boost upto 1.3 ish and you'll probably be close to getting a second off...... turbo life will shorten though Link to comment Share on other sites More sharing options...
lust2luv Posted July 22, 2003 Share Posted July 22, 2003 Originally posted by pulse Drive it off a Cliff ?? That'd be 0-60 in 2.7sec according to a quick rough calculation on the back of a fag packet. Bragging rights wouldn't last long though, dependent on the height of the cliff.

I wonder if that'd beat a proper bike.. probably not, more wind resistance in the Supra, the bike would fall a fraction faster. boo -p Link to comment Share on other sites More sharing options...

Terminator Posted July 22, 2003 Share Posted July 22, 2003 Power to weight is the problem, getting all that mass of the MKIV moving takes a lot of torque. TVR's weigh as much as an egg box so they always going to be very quick off the mark. But they have to say running long enough to achieve a quick 0-60. Reliability is often an issue. (I have a friendd who services them, very often.) A well maintained MKIV will go forever, well at least 300,000, with out much required. It all depends what you want out of the car, mid range on a lightly mod MKIV is pretty stunning. If you want sub 4, 0-60’s get another car or re-mortgage the house.

qaisar Posted July 22, 2003 Share Posted July 22, 2003 if its for the strip how about drag radials, like someone said traction is gonna be ur worst enemy for 0-60 (or if u ask matt h for the whole 1/4 mile ) Link to comment Share on other sites More sharing options...
eyefi Posted July 22, 2003 Share Posted July 22, 2003 if u wanna spend money, the best off the line mods have gotta b higher stall TC and cats out with powerbraking. i reckon that'll come close to a second off a bog standard start and feel quite aggressive from the passenger seat.
