new here and thinking about getting a Supra
Hi Everyone, I have been looking into getting a supra for quite some time and I have quite a few questions that I hope can be answered here. Let me start off by saying that I am looking to get a TT 6speed MKIV Supra. I will also give you a little insight on why I want a Supra and what I will do with it. First off I just want to state that the Supra is absolutely a sex machine and is one of the best looking cars in my opinion. I have always wanted one but it was impractical for a first car and now I have a slight chance to get my dream car. So enough chit-chat I will be keeping the car stock (or with whatever upgrades may come with it) for a while. I will slowly upgrade it but I am very young so money is a big issue. I just want a fast, sexy daily driver not a full race car. I want to be able to do weekend drag racing and maybe even autoX. I hope this does not boar anyone but I have a TON of questions and thanks in advance for your answers!
Well my first question is simple. What do I look for when buying a supra?! any rust spots any engine components that break or need replacing a lot? Any little tips for what too look at will help me a ton. Also I am wondering what a decent price is for a TT, 6-speed I will look at any years above 93 but most likely years 95+ because I will only get a car with less then 50k miles. Condition is also very important too me I will pay more for quality but I don't want to get ripped off. I have a few questions about what to do with my Supra. I was thinking of a single conversion because it seems cheaper then upgrading the TT. Is a BPU a good idea or is it better to peice together a single turbo setup. Also what is a good BPU or "parts" to get about 400whp and still be able to go over that easily. How far can you push the stock block and fuel system? Also I am wondering what top mph a stock or slightly modified Supra is goverend too I am assuming around 150mph? What do you have to do to by-pass the speed governer. How important is a upgraded ecu and tuning? does every small upgrade require tuning? What is better a stand alone or a piggyback or does it even matter? Also I have a few questions about modifing the supra. What is a good start too upgrading a stock Supra? Intake? boost controller? exhaust? Last but not least what all will I need to get 400rwhp? will 91octane still be able to be used at these HP levels? Also I want to aquire around 400whp but still have room to boost it up in the future. So what do I need? Turbo? Fuel? Internals? Piping? etc... Thanks for all your help I was thinking of just saving for a decent BPU witha few supporting mods, is this the best route for me to go for what I want, or is there other paths to take? All help greatly appriciated |

Several other items, such as cooling system components can fail, if the Supra was not well maintained. Quote:

Also, don't forget to increase your octane with race fuel when you increase your boost, or (like I said above) your pistons will get damaged. Note that the damage doesn't happen instantly, because the oem ecu tries to retard timing when it detects detonation, but this doesn't always happen fast enough. Damage over time is guaranteed if you repeatedly run high boost on pump gas. Quote:

Wow! Thank you for the great response to my questions. I would just like to say yes Auto Trans may be better but nothing is more fun then a 6-speed and I am not too concerned with drag racing, its just for fun. Autox would just be a fun thing but yes I considered roadracing although I havent looked into it very much.

Oh, I forgot to mention in my previous post that you can use a meth+water injection kit (instead of race fuel) to increase the net octane level, and safely raise boost. Quote:

Also I was wondering if you knew of any good shops to work on Supras in Vegas. I know Virtual Works is here but im not shure if they work on public cars or not. Thanks. |

 ) and not methanol.Methanol (or any alcohol) is a bit corrosive though (especially to aluminum)...so if you install a meth kit and then boost a lot, it's best to drive your car around for a couple of minutes afterwards to flush all of the meth out of your intake system. Quote:
Lastly, please note that there's a lot of other great information on the links posted in this thread: http://www.toyota-supra.info/forums/...ead.php?t=7287 ...many of the questions you asked above are addressed in more detail at those links.

my 0.02
I would recomend a manual transmition for any type of racing over automatic any day. Due to the way an automatic works you typicaly suffer a %5 power loss through the drivetrain. There may be a few good examples of automatics at the racetrack ,but the manuals dominate by far for a reason. I would also think the manual preferable for autox as well ,due to the fact that you can keep your transmition in the power band more ,ie. shift down to 3rd when going through a turn so your at the top of your gear when you come out and are in your torque curve. I've seen some pretty unlikely candidates hold their own on the track as well. A good suspension setup goes a long way. I have seen big ol' muscle cars turning rather competetive timeslips ,which I would never expect. Sounds like you have a pretty realistic dream to me and have given this particular car a bit of consideration. I think you would be very happy with it. Good luck and happy motoring.

http://www.toyota-supra.info/forums/...ht=auto+manual Any given driver in an Mkiv Supra Turbo in the 1/4 will generally be more consistent AND at least a half second quicker with an auto (vs. manual). In other words, in the Mkiv Supra Turbo world, manuals do not dominate in drag racing...they are significantly slower. This is not an opinion, it is a fact, repeatedly proven by the results of hundreds and hundreds of Mkiv Turbos at the dragstrip. Please don't forget that a bone stock mkiv tt does low 13s, and a bpu mkiv easily does 12s - I'm specifically and only referring to results achieved with this particular vehicle (i.e. not drag racing in general). Also, launching any turbo car with a manual tranny is very much an art. You're usually stuck launching at zero boost, depending only on your revs and driveline/flywheel inertia to get out of the hole. Then it instantly becomes a very fine line between spinning and gripping/bogging as boost comes up...modulated by feathering the clutch (since modulating the accelerator would almost surely take you out of boost again). It can take literally hundreds of passes down the dragstrip to get that process perfected...and in general, the 6spd looses so much time getting to the 60' that there's no way on earth to make up that lost time on the back end, even with 5% more power. Without serious drag-specific modifications like a 2-step rev limiter, nitrous, slicks, line-lock, etc. to assist him, an auto tranny would most certainly be a better choice for WhisPer if he wants to get consistently quick times at the drag strip. Fwiw, I do agree with WhisPer that a 6spd is more fun to drive, and if you're only going to the dragstrip to have fun, then a 6spd is a fine choice. However, pretty much everyone I know that goes to the dragstrip actually does care about the times that they get. Since WhisPer hasn't purchased his Supra yet, I'd suggest he should at least understand that he'll very likely be slower in the 1/4 with a 6spd (despite the additional driveline power loss). Quote:

 . Yes I agree suspension is very imprtant. Do you think some adj. shocks with a lowering spring would be sufficient or just a full adj. coilover system? I also might get a front and rear sway bar and a few strut bars.Also I was wondering how the clutch is on a mkiv does it hold power well? I hope so because now I'm driving on an aftermarket ceramic 6-puck with a lightweight flywheel and my 1st gear is next to impossible for daily drivng. |
