Guest B-Dub Posted April 19, 2012 Share Posted April 19, 2012 Seeing as I havent even bought my supra yet & i'm still looking for the perfect one, I wanted opinions on which to get? I've been told by a few mates that i should get a single turbo manual as its less to go wrong and i could get more out of it.. But surely i could get more out of the twin turbo and sure too i'd have more fun with it? What do you guys say? Quote Link to comment Share on other sites More sharing options...
Josh Posted April 19, 2012 Share Posted April 19, 2012 Twin turbo = 2 small turbos, topping out at 450bhp Single turbo = 1 large turbo, topping out at 1,000+bhp Aftermarket twin turbos, the same as the single turbo. Quote Link to comment Share on other sites More sharing options...
Ricky49 Posted April 19, 2012 Share Posted April 19, 2012 You will have to get a stock Twin Turbo or a modified single turbo or modified big twin turbo. Quote Link to comment Share on other sites More sharing options...

Noz Posted April 19, 2012 Share Posted April 19, 2012 Twin turbo = 2 small turbos, topping out at 450bhp Big Twin Setup OR Big Single turbo = larger than stock turbo(s), topping out at 1,000+bhp Depends on how you want the power delivered. There is no difference in what power is reachable. Quote Link to comment Share on other sites More sharing options...
spikedjack Posted April 19, 2012 Share Posted April 19, 2012 You will have a lot less hastle with a stock or bpu'd motor than you will with a single turbo'd car someone has built. Quote Link to comment Share on other sites More sharing options...

There is no difference in what power is reachable. Not that this member will be building a 1000bhp twin but I am not sure this advise is that sound, how many very big twin kits do you know and they tend to be much more expensive to build when you do get them Would be good to know the members age, budget, experience of rwd, aim of build etc Quote Link to comment Share on other sites More sharing options...
Noz Posted April 19, 2012 Share Posted April 19, 2012 I just copied post #2 from Josh and included big twin set up. People dont consider large twins its just BPU or Single too often. Quote Link to comment Share on other sites More sharing options...
Rob_Mitchell Posted April 19, 2012 Share Posted April 19, 2012 I agree, to build a decent big twin motor like lee's srd supra, its got to cost more than just going single? Quote Link to comment Share on other sites More sharing options...

Nic Posted April 19, 2012 Share Posted April 19, 2012 (edited) The MKIV Supra came factory fitted with 2 relatively small turbos, these operate sequentially ie. the first turbo spins up and then at just over 3Krpm the second turbo comes online, this gives good low down response plus good top end power. As standard the TT makes around 320hp, but with simple modifications (click -> BPU) removing the catalytic convertors and upping the boost it's possible to raise the power to around 380-400hp. All single turbo MKIV Supras are modified, ie. the stock sequential turbos are removed and in their place is fitted a larger aftermarket single turbo kit, these can vary in power - depending on the spec of the turbo, engine and other supporting modifications - from anywhere between say 500-1000+hp. Power is not measured by how many turbos are fitted, it's about how much air the turbo(s) force into the engine. So you could have 2 small turbos that flow less air to the engine compared to one large turbo, likewise you could have 2 medium sized turbos that flow more air into the engine than one larger turbo. If it's your first Supra I would look for a standard twin turbo Supra, start by having a read through the threads below. http://www.mkivsupra.net/vbb/forumdisplay.php?60-Basic-Supra-Guides Edited April 19, 2012 by Nic (see edit history) Quote Link to comment Share on other sites More sharing options...

stevie_b Posted April 19, 2012 Share Posted April 19, 2012 Hello B-Dub, OK, reading between the lines, I'm guessing you didn't realise that single turbo mkIV supras are highly modified, bespoke cars. Toyota never made mkIV supras in single-turbo format. I'm also guessing you think twin turbo systems can deliver more power because there's 2 turbos instead of 1. This isn't generally true, but it's an easy mistake to make. I thought that when I first joined this forum. If you want simplicity (in terms of the engine being standard-ish) and reliability, go for a twin turbo. If you want lots of power and are prepared to pay several thousand pounds more for it, go for a single turbo. Quote Link to comment Share on other sites More sharing options...

Guest ugp Posted April 19, 2012 Share Posted April 19, 2012 The only issue with big twins as it's twice the hassle to fit, and when it goes wrong, twice as expensive. Quote Link to comment Share on other sites More sharing options...
tkddav3 Posted April 19, 2012 Share Posted April 19, 2012 single ftw! but jumping into a single turbo rwd car for the first time. your gonna boot it (as i did) and can easily take the wee wee and you will end up in a hedge driven annything like a supra before?

Graham1984 Posted April 19, 2012 Share Posted April 19, 2012 Get a NA and cry your eyes out instead. In all honesty if you have never driven a RWD car before then both the TT or single options may be having you visiting the local ditch and catching up on the current state of the Nhs care system sooner or later.
