Guest joph Posted August 21, 2008 Share Posted August 21, 2008 Hi Guys/Girls, Probably a bit of a naive question because I havent brought a Supra TT yet, so I dont mind getting hammered for it as long as I learn :0) Do you have a feature on a Supra Twin Turbo where by you can bypass the turbos?

SilverSoop Posted August 21, 2008 Share Posted August 21, 2008 Why would you want to do this Joph?? Do you mean a TTC?? (True Twin Conversion) Quote Link to comment Share on other sites More sharing options...
JustGav Posted August 21, 2008 Share Posted August 21, 2008 No, is the easiest answer.... It is possible but it wouldn't be a simple solution and certainly wouldn't be cheap. As to why, I can sort of understand the logic, start off getting used to the car and then bring the turbos in once you are used to it. Good logic, sadly can't be done. I'm sure someone will make some comment about getting an NA. Quote Link to comment Share on other sites More sharing options...

stevie_b Posted August 21, 2008 Share Posted August 21, 2008 I've often wondered this. So peeps here are saying that the turbos can't easily and safely be fudged to produce no boost? The OP's question could be taken in 2 different ways: 1) stop the turbos spinning altogether 2) allow them to spin as normal, but don't allow them to push air into the engine. This is the one I'm referring to in my question. PS I already have an NA Quote Link to comment Share on other sites More sharing options...
Wez Posted August 21, 2008 Share Posted August 21, 2008 Please dont tell me this is to save on fuel You could wire the wastegate open Quote Link to comment Share on other sites More sharing options...

PS I already have an NA Yeh but why on earth would you want to stop the turbo's when the purpose of the TT engine is to force induction into the engine by means of 2 turbo's. Stopping the Turbo's cant do much for the engine... So, i would get an N/A when it's just naturally aspirated... Quote Link to comment Share on other sites More sharing options...

This is the one I'm referring to in my question. PS I already have an NA You could just fudge the wastegate but i think there would still be an issue with J-Specs as the wastegate isn't big enough so just as he is getting used to driving it as an N/A he rev's to over 4000rpm, 2nd tubby comes on and he flies into a ditch sideways. Not sure about this though as the wastegate should be ok as long as the boost hasn't been tampered with lol. The turbo's aren't the problem though, the driver is. Its all about your right foot and getting over excited. Quote Link to comment Share on other sites More sharing options...

SilverSoop Posted August 21, 2008 Share Posted August 21, 2008 http://www.mkivsupra.net/vbb/vbpicgallery.php?do=view&g=1769 Ahh, thanks again Gaz... :-) That is interesting though, i didnt think you could stop the tubbies on the TT as basically, that's the engine's purpose... I stand corrected... :-) Quote Link to comment Share on other sites More sharing options...
Flip Posted August 21, 2008 Share Posted August 21, 2008 Could just pull the intercooler pipe off the throttle body and replace with a cone filter - the car would be hopelessly overfuelled and run like a pig of course... but the desired effect of no boost would be achieved!

Rob Dublin Posted August 21, 2008 Share Posted August 21, 2008 (edited) Possibly a traction aid? Button on the dash that stopps the turbo kicking in around town/roundabouts. Simple solution in that case would be RLTC. Bigger balls another solution Edited August 21, 2008 by Rob Dublin (see edit history) Quote Link to comment Share on other sites More sharing options...
Scott Posted August 21, 2008 Share Posted August 21, 2008 Yeh you could but why buy a TT if you don't want the Turbo's to work?? I'm just guessing here but its the only semi logical explanation i can come up with. He wants to have a TT but has never driven a RWD car let alone one with upwards of 300bhp. He wants to be sensible and decides that it would be better to learn to handle the RWD with limited power before going the whole 320bhp hog. His 2 choices are either to buy an N/A then progress to a TT (waste of money if your aim is a TT and you can afford it just now) or work out a way to limit the power until he is ready (wanting to negate the tubby's). IMO there is no need to drop the power of the TT as it is still controllable via a varied right foot. If you know whats under there simply don't press it until you are confident. Going from an N/A to TT comes with the same risks, the grin factor Quote Link to comment Share on other sites More sharing options...

Going from an N/A to TT comes with the same risks, the grin factor Yeh i see where you're coming from but the usual route is upgrading from n/a to a TT... Surely though, it cant do much for the TT, if the turbo's because that's the way the TT is designed... Im probably wrong but, it's just the way it sounds...

If you had the money to buy, insure and run a TT... would you buy an N/A? I know i wouldn't. If the only thing holding someone back is fear then its a missunderstanding of how a car works. Yes the TT can get you into trouble quicker but only if your not being careful. At legal and safe speed's there is no difference between a TT and a corsa, cept the TT would brake better and the corsa would be getting 50mpg.

Yeh i know Scoster but im thinking that because the way the TT engine is designes, it cant be good to cut them out...surely... Or you could drive at low revs and not hit boost until you are ready... ;-) Quote Link to comment Share on other sites More sharing options...
