mikeysupra Posted February 5, 2006 Share Posted February 5, 2006 short of a na-t turbo conversion or nitrous oxide are there any decent performance upgrades available, throttle bodies, intakes etc Quote Link to comment Share on other sites More sharing options...
mikeysupra Posted February 5, 2006 Author Share Posted February 5, 2006 or is it worth sticking nitrous on it or saving for a na turbo conversion? Quote Link to comment Share on other sites More sharing options...

Guest slow dog Posted February 6, 2006 Share Posted February 6, 2006 tubular exhaust manifold nos de cat ecu cams big valve head port polish up the compresion etc etc the list in endless mate i fitted gas to suprababe's car goes like furk mate only problem with it is that 50 pound for a tank of gas for 1 minute 30 is alot of money but worth the rush Quote Link to comment Share on other sites More sharing options...
mikeysupra Posted February 6, 2006 Author Share Posted February 6, 2006 do you know anywhere i cat get a decent de cat from? 1 min 30 of nos thats not good lol how bigs the bottle? Quote Link to comment Share on other sites More sharing options...
Faye Posted February 6, 2006 Share Posted February 6, 2006 Chris Wilson does decat pipes for the NA, as does I believe Paul Whiffen Quote Link to comment Share on other sites More sharing options...
Pete Posted February 6, 2006 Share Posted February 6, 2006 CW Decat on my NA - thoughts. http://www.mkivsupra.net/vbb/showthread.php?t=37357&highlight=decat Throttle bodies are an interesting avenue, but prohibitively expensive. Someone in the USA was doing it. I'd love to see it done. I know it's cheaper to turbo it, but the 2JZ-GE must be capable of some serious power without a turbo.

attilauk Posted February 6, 2006 Share Posted February 6, 2006 i would love to see someone make a good go at building a mad spec N/A 2JZ, just for the noise more than anything Quote Link to comment Share on other sites More sharing options...
mikeysupra Posted February 6, 2006 Author Share Posted February 6, 2006 yeah thats what i,m going for mate think de cat next on shopping list thanks for the help guys! does chris wilson have a web site? Quote Link to comment Share on other sites More sharing options...
mikeysupra Posted February 6, 2006 Author Share Posted February 6, 2006 oh has any one with a na put on a de cat and had a rolling road i,d be interested to see the power gain? Quote Link to comment Share on other sites More sharing options...
Pete Posted February 6, 2006 Share Posted February 6, 2006 does chris wilson have a web site? Yes...if you like pictures of Emus Seriously, he's never needed a commercial site as such as he gets so much work through recommendation. Quote Link to comment Share on other sites More sharing options...
mikeyb10supra Posted February 6, 2006 Share Posted February 6, 2006 or is it worth sticking nitrous on it or saving for a na turbo conversion? Forget the nitrous oxide.....read the horror stories on here for why not to use it....De-cat, cams and failing that a turbo is the way to go Quote Link to comment Share on other sites More sharing options...

JohnA Posted February 7, 2006 Share Posted February 7, 2006 short of a na-t turbo conversion or nitrous oxide are there any decent performance upgrades available... not really. Not if you use an accelerometer to measure the real performance hikes. (because extra sounds and self-convincing might well say otherwise) To get a decent performance gain from this engine you need to get a lot more oxygen molecules in (so you can pair them with fuel molecules and get power) Short of nitrous or super/turbocharging nothing can do the job properly. If it was that easy, Toyota would have done it already. Quote Link to comment Share on other sites More sharing options...
lust2luv Posted February 7, 2006 Share Posted February 7, 2006 Removing 200kg from the cars weight would be the approx equivalent of a 35HP hike on a stock NA, putting you not a million miles off a jspec TT's power per tonne when combined with a full decat, certainly more than can be achieved without using NOS or forced induction, and a lot cheaper too, if you can live without luxuries. Anyone tried it? With some of the tatty, ridiculously cheap NAs floating around these days, it'd be an interesting project. Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 7, 2006 Share Posted February 7, 2006 Removing 200kg from the cars weight would be the approx equivalent of a 35HP hike on a stock NA, putting you not a million miles off a jspec TT's power per tonne when combined with a full decat, It will probably need to lose a lot more than 200kg to come anywhere close to the TT's bhp/ton Very roughly, let's say that the stock TT is 1500kg and makes 320bhp. That's 213bhp/ton Let's say that the n/a only weighs 1400kg and makes 220bhp. That's 157bhp/ton Now even if that n/a is down to 1200kg and it manages another 5bhp from the decat, it will still be 187bhp/ton. You'd need to bring the weight down to 1 ton if you want to be competitive with a stock TT (which also has oooodles of torque around 4Krpm that a n/a cannot compete with) See it this way: a TT can do 40-100 in 10seconds flat. Get an accelerometer and try it with a n/a. You'll get an idea of how far apart they really are. Quote Link to comment Share on other sites More sharing options...
lust2luv Posted February 7, 2006 Share Posted February 7, 2006 Was assuming the jspec TT was nearer 1525KG and 310HP, allowing 75kg for a driver, and 240HP for an NA with full decat and exhaust, that gave 188HP/ton for the NA and 194 for the TT. Picking a 40-100mph test out of the air would obviously be playing into the TT's hands (c. 12 sec for the stripped NA I would have thought), a 0-60 test would be closer and for a lap of a track my money would be on the NA. Assuming that amount of weight could be shed, it would certainly be a more interesting direction to head I feel when it comes to modding an NA.

JohnA Posted February 7, 2006 Share Posted February 7, 2006 Was assuming the jspec TT was nearer 1525KG and 310HP, Are you implying that the JSpec is making 16bhp less than the UKSpec? oooooh you've opened a Pantera's box now allowing 75kg for a driver, That counts me out then and 240HP for an NA with full decat and exhaust, 20bhp from that? I really doubt it. Only if you use the exh supplier for pre/after dyno runs:eyebrows: Picking a 40-100mph test out of the air would obviously be playing into the TT's hands why pick it out of the air? You can bleedin measure it. 40-100 is handy because it avoids standing starts that are hard on the transmission, and speeds don't get too high either. It indicates real-life power delivery. Assuming that amount of weight could be shed, it would certainly be a more interesting direction to head I feel when it comes to modding an NA. But if you can shave half a ton from the supra, it won't be a supra anymore. I would just be a bare shell, comedy bucket seats and the engine block. You could have the same effect with nitrous or a turbo while the aircon is blasting in your face and the ICE is drowning the noise Quote Link to comment Share on other sites More sharing options...
lust2luv Posted February 7, 2006 Share Posted February 7, 2006 Well mkiv.co.nz quote 300HP for the jspec, but lets not go there! My point being, after an aftermarket exhaust and decat, people start spending four figure amounts on headers, cams, etcs to eek an extra 10HP or so from the NA, when you could get the same effect by shedding a bit of weight - spare tyre, tool kit, rear seats and sub would almost do it I would have thought. Obviously a turbo would give you way more power, but then you're talking £4K+, which is probably the value of the car! Quote Link to comment Share on other sites More sharing options...
JohnA Posted February 7, 2006 Share Posted February 7, 2006 It's gonna cost money to shed significant weight from the car, too. Replacement 'racing' buckets etc don't come for free, do they? Then you pay through the extra devaluation of the car - it won't fetch the same without aircon etc, will it? And if you want to set it for track use, then a n/a supra is totally the wrong place to start. Too big, too heavy and not enough power. It will never be an Elise, lol...

Need4Speed Posted February 7, 2006 Share Posted February 7, 2006 for a lap of a track my money would be on the NAOnly on a kart track! I reckon I could get an easy 350kg off but you'd end up with a car that's useless on the road. You won't have a stereo or a passenger seat or any sound-proofing or trim or underseal... and it'll cost more than a TT to do it. Quote Link to comment Share on other sites More sharing options...
lust2luv Posted February 8, 2006 Share Posted February 8, 2006 Re-read my post above, I'm talking about minor weight reductions being more cost effective than extensive NA modding - the rear seats are pretty useless anyway, and you could keep the AC (although I use it maybe once a year in this country). Likewise I'm saying it'd be interesting to see someone buy a tatty NA for £2-3K and rip it apart for track day use. Of course you could buy an Elise (but not for £3K!), but that's hardly the point is it? It's to try something that hasn't been done (AFAIK). This is a Supra owners club isn't it? Devaluation doesn't come into it - the minor weight reductions could all be reversed easily and compare favourably to pissing away £2K on mods that's add virtually no value to the car. The track car is dirt cheap anyway, it wouldn't be an investment. I'm hardly advocating turning your daily driver into an empty metal bucket with one seat in order to beat a couple of extra cars in a traffic lights grand prix.

JohnA Posted February 8, 2006 Share Posted February 8, 2006 OK, chill out now.... ........breathe in.......... ..........................................breathe out................ It's a good idea actually. It will create more traffic in the 'for sale' section, benefiting the Supra community, helping keep more cars on the road;) Quote Link to comment Share on other sites More sharing options...
