9 second Supra?
 

Well i finally have the money to get my dream car, but just one question. What mods do i put in an MKIV to make it a 9 second car. please post the mods and what the final car's price, horse power, torque, estimated 1/4 mile time, est. 0-60 time, etc. would be.

Here you go...but note the following: Very rough estimated prices only...using only brand-new brand-name parts (i.e. no cheap ebay crap, or fumbling with used parts with no warranty)...major items listed only...also assuming that a reputable shop already experienced with Mkiv Supras does the install:

• $25K for mid-mileage '94-'97 mkiv supra tt auto, in good shape (no salvage title)
• 1000+hp-capable fuel system: $2,500 + $700 install
• 1000+hp-capable turbo kit: $5k + $900 install
• 150 wet shot direct port nitrous kit: $1500 + $1000 install
• Upgraded 2jz-gte internals (eg. connecting rods & bearings) and headwork: $4K (parts) + $2k headwork + $3K uninstall, machine shop work, reinstall
• Race Cams $1k, install included in previous bullet/item
• 4-row fmic: $2K + $500 install
• 4" exhaust: $1500 + $100 install
• Full race intake plenum & TB: $2K + $1K install
• Complete SP400 Tranny Swap kit (no overdrive): $5500 + $500 install
• Carbon-fiber Driveshaft $2k
• N/A Brake conversion: $1K + $300 install
• Drag Coilovers: $2K + $400 install
• Drag Rims&Tires (Full Race Slicks & 'Skinnies'): ~$3K
• Standalone ecu & dli/cdi: $3K + $500 install + $2K tuning (yes, at least $2k for tuning)
• Race Fuel: about $500/barrel
• I'll let someone else do the math to figure a total...

Even if you're a crappy driver (which you may not be, but just covering worst case scenario), this setup gets you in the 9s (1.75 or better 60's, and I'd guess about 140 mph or so). It'll put out about 900rwhp (this is the equivalent of about 1100rwhp through a 6spd). Note that a truly gifted driver could get into the 9s with less investment, but the list above is a guaranteed 100% for sure 9 second setup.

Also, NB: Although a roll cage & other safety gear is desireable, and probably required at most tracks, I haven't included it because the car will (as per your only stated goal) run the 9s without these safety mods.

i think that comes out to be $49400 WITHOUT the car. ehhhh that's a lot

Is that all? ;) Yep, 9 seconds (guaranteed) doesn't come cheap, IF you're talking about doing it with a car like the Mkiv Supra that will also handle like mad in the twisties. Also note that a gifted dragracer might even hit 8s with this setup. ...but if all you care about is straight-line acceleration, then building up (for example) an older sold-axle Mustang will get you to the 9s for significantly less $.

Fwiw, about the least-modified Mkiv Supra I know of in the 9s, did so with a 100% bone-stock longblock and a fuel system, T72 turbo, ~75 shot of no2, cams, racing clutch, fmic, vpc+gforce modded ecu, 2-step rev limiter and bfg drag radials. The gentleman driving this setup was a well-known, naturally gifted & very experienced drag race driver. This is typically what I'd call a 10 second setup (for any moderately experienced drag racer) ... but note that effectively launching any turbo car with a 6spd is almost an 'art' rather than a science (i.e. it's not easy at all to learn to do). In theory, another less-expensive way into the 10s would be using a bpu++++ Mkiv Supra, a 'built' oem auto tranny (~$3,500), slicks and a huge direct-port shot of no2 (note: robust electronic controls and extensive tuning would be highly recommended to safely/reliably run that 'huge' shot of nos)...

Lastly, note that in general, $50K in modifications to an Mkiv Supra really isn't that unusual. Imagine (for example) if we wanted to take the 9-second Mkiv Supra we built above and ALSO make it full NHRA-legal safety equipment AND show-ready too! Throw in a roll cage, 'chute, custom interior, custom sound system, widebody kit, high-end paint job, chroming and bling parts in the engine bay, etc. and we're easily deep into the 6 digits including the cost of the car ... anyone that has been to a national Supra meet (eg. Tx2K5 or SILV) has seen several Mkiv Supras 'done up' like this, with huge inve$tment$ in modification$.

ok, thanks for yer suggestions :D i guess i am a fairly good driver ;) been usin my turbo ctr for around 5 years

What's a "turbo ctr"? Is it a Porsche? If so, what kind of times do you run?

heh, no, my first car was a civic type r w/ turbo kit...if its not too much trouble, could u post what brand and type i should get for those parts? :-\

I wouldn't suggest piecing this together. Imo, you really should be working with a shop that can properly engineer the entire package for you...so that it all works together and the results can be guaranteed. In general, most of the parts I'd recommend come from JUN or HKS...and the SP400 tranny comes from Sound Performance. If you'd like to PM or email me I'd be happy to get into more extensive detail...

yeah, i was thinking of asking a shop and tell them the general parts u told me, and they maybe suggest another part, and put it together, :) thanks pwpanas for yer help! i might email u sometime

Ok cool. I know a good mechanic in Arizona that I'd recommend when you get ready to go ahead with this project...

It is not just about the horsepower but the driver.

Agreed, but if you've got a 950rwhp Mkiv Supra Turbo with a TH400+trans-lock, nitrous (for spool-up), and slicks, the d@mn thing is pretty much point-and-shoot. Getting it into the 10s would be child's play, and 9s only a matter of practice after that. In truth, it'd actually be an 8 second car, but THAT would indeed be highly dependent on the driver.

In addition, I'd point out that although the driver's skill is a significant factor in drag racing (up to let's say 10%-25% of the time component), in roadracing the driver's skill is many times more important (probably closer to 50% of the time component).

Why 2jz-gte?
 

After reading your post pwpana, and being a bit of an ametuer enthusiast, i was left wondering why you would fork out an extra 10k for a TT model when your putting in aftermarket parts to replace existing turbo, exhaust, etc.

Im sure there would be a short answer but as i myself am considering modding a supra id love to know as much information before i begin the project, thanks in advance ;)

Here's my short answer, for a start: It all depends what you want to do with the car, and how much effort you want to spend. If you want an all-around performer that can be regularly street-driven and can also run 9s ... and in addition you want to minimize the overall work you have to do to get the car into the 9s ... then you probably want to start with a TT. Of course, the oem TT already comes with the much more capable 2jz-gTe engine, which is very different than the non-turbo engine. This means the ecu and engine harness is very different as well. The oem driveline and diff is more capable in the TT too.

On the other hand, I agree that if you're planning to build a stripped down racecar that will be trailered to the dragstrip and it's equipped with fully 'built' and/or aftermarket parts, then you might as well start with a non-turbo, or even a salvage chassis and go from there...

Yeah i thought it might go something along those lines, thanks for the reply mate :)

buy most parts from TRD. i just find it alot more reliable. most tC owners buy their superchargers from TRD as well as headers. get a cat-back exhaust, cold-air intake, just the basic needs to produce 50-100 hp gain =/
what else can i say w/o looking under the hood of your car.

Rofl. TRD doesn't make most of this stuff...mainly because the Mkiv Supra hasn't been manufactured for several years. In fact, I'd be willing to bet that TRD doesn't even make enough bolt-on parts to put a tC into the 9s...and that was SupraFTW's question: "What mods do i put in an MKIV to make it a 9 second car".
You probably shouldn't say anything else (on this topic) imho...SupraFTW was asking what modifications would need to be made to a STOCK '93-'98 Supra Turbo in order to get it to run 9s. The only thing you'd find under the hood of a bone-stock supra are the bone-stock components. What else would you expect?

TRD uses aftermarket parts and puts their logo on them. For example, TRD struts are manufactured by KYB.

go to trdsource.com
trd manufactures parts

http://www.trdsource.com/toyota.asp

type in the model (supra), year, and engine (turbo)
then look down and you see a table. hope i didn't lose you already 'cuz we're almost done. at the right side of the table, you see a list of manufacturers. read it for yourself.

trd actually makes much more but they rarely update their list. if you go to your local toyota dealership (supraftw) you can ask them there or you can just call them.

as a matter of fact. trd does produce superchargers use the same site and look up tC's. all you gotta do is read magazines. or have friends.

i dont know where you are getting these outrageous prices but for those kind of prices they better come with gold plating and a good blowjob

Rofl I'm sure you can get better pricing for civic or rustang parts from bubba's knock-off mild steel header & exhaust press-bending service. Unfortunately, quality parts (that fit and work properly & reliably right out of the box) for an ultra-rare $70K GT Sportscar tend to be a bit more pricey.
