Car Choice...
 

Well I'd like to introduce myself my name is Nick first off. Second I'm glad to be here. Here's my dillema...Right now I'm in the process of selling or trading in my 97 Svt Cobra and I will be in need of a new car soon. The 3 I'm looking at are:

04 Cobra
Acura Nsx
Supra TT Mark IV

The problem is, I can't decide what to get. Personally That would be the 3rd mustang I've owned and as much as they are in my blood and passion, I'm bored and want something rare and different. The Nsx is a very rare car in my area as is the Supra and for shock value alone I would love. What I'd like from you all is as much info on a year I should be looking to get specifically,prices, power, weakness, motor specs (internals) etc on the Supra and even some pro's cons of each car if you didn't mind. I'll even start..

04 Cobra - Factory underrated and usually dyno around 360 rwhp. S/c'd and 6spd. BUT Independant rear is terrible for the strip unless beefed up, and usually clunk out around 500 hp

Nsx - Rare around here, awesome look, and just as fast as my current car now. BUT not turbo'd, very pricey and hard to find something really decent.

Supra TT Mark IV - I know almost nothing about them other than they are rare here and are damn quick :). Twin turbo's are my selling point which I've always wanted a TT'd car. The car to me seems setup for the option of going to bigger turbo's from the factory but I could be wrong. The Targa Top option is definately something I'll be looking for though. BUT not sure on the forged internals part, if the 6 spd's are reliable/rear ends as well.

That's it for now everyone. Like I said I know nothing about these cars and want to learn as much as I can before I decide on what to buy. Thanks and I look forward to everything you have to say.

Have owned 6 mustangs..
 

1. NSX forget it if you are over 6 foot. Slow car for the price. 14.5 - 14.7 is what they do in the quarter mile at Seattle International raceway. (I stood there and watched) My 94 stang did that stock.

2. I have owned 6 mustangs.. great straightline car - have to put a few thousand into the suspension to get them to handle.. low resale value - not put together well.

3. I am going to buy a Toyota supra this afternoon.. :-)

I'm actually 6'2 lol so yeah a bit of a problem then. Yeah my cobra is great but mustangs are too common and boring to me to own now...Just to work on because it's my job. But as far as a Supra goes the style of the Removable top/roof is just so appealing to me. Its a nice design I think. Anyone else?

I thought Nsx's ran 13's as well?

Anyone else want to chime in?

Supra, all the way. Alot more fun and way more possibilties with the supra. With the NSX parts are very expensive and rare. But with the Supra parts are common and not quite as expensive. Looks better too. As far the conversion from American Muscle to Import Power, that's your call. Good luck! My votes for the Supra.

brother, you asked the wrong site that question. of course everyone will say supra here. dont get me wrong though, those are awesome cars, and anyone would be proud to have any of them.

for the mustang, too popular but big market
nsx, very rare but i dont like anything other than a frountmount motor
so my choise is of course the supra. one of the best motors out there. there is no arguament that the block is very well built. there is a growing market for these retired cars and because they are rare and growing rare, their resale price stays constant. if you got the option to get the tt 6sp model, you better get it before someone else does. you wont be unsatisfied. and if you dont like it, you can sell it to me :bouncy:

Yup that will be the choice 6pd TT Targa Top model :) I figured if it's what I wanted I could just sell it and get something else. But as far as switchig from american to import, never bothered me, Im not a typical mustang guy. I have respect for anything fast and the potential is endless.

Re: Car Choice
 

Didn't the Acura NSX only come with an automatic tranny? What a waste. Buy the Supra 6 speed, I'll bet its lots more fun!

No!
 

To the last poster: Hell no! They came manual as well.

To whoever said NSX's ran 14.7 stock - Dude, you have no idea what you're saying. The stock time is around 14.0. It's a 280HP car, and it's not nearly as heavy as the Supras are (either MK3 or MK4)... yeah, you have to rev it up to get the power, but still, 14.5-14.7 can only mean one thing: VERY SHITTY DRIVERS were at Seattle bro ;)

I once ran a stock NSX with my 300ZX TT, I was at stock boost and drove poorly (missed a shift), and it got me. It ran 13.7 ... I think he had aftermarket air intake and exhaust, but that was it.

Anyways, NSX have their own reasons to be so desired. All that power from a tiny 3 litter engine, normally aspirated.. it's something to admire. Also, it's ability to take corners is just breathtaking... u guys seen the videos where the NSX keeps ahead of the 2 lamborghinis in the 5 lap run? Those japanese videos are the best. NSX would clearly screw those Lambos up in the curves, but then the V12 caught her up in the straight line and in the 5th and final lap beat it, aww :( ... NSX is not a slow car, specially if you have to turn. But if you wanna drag or street race, yeah, I reckon the V8's will eat it alive.

Supra MKIV TT is awesome stuff. I know stock it's in the 13.6's or so so, but it's not it's stock numbers that impress everyone, and it's not those numbers that have made it grow so popular... It's how easy and simple it is to gain another couple of hundred HPs... Very easy. The engine is very well built, with stock internals you can handle a heckload of HPs... 700 or so? More than I would ever want. And I repeat, this is with stock internals.. just buy big injectors, good intercooler/pipings, big turbo, wide exhaust and a boost controller :P .. if it's ur daily driver, just run it at stock 9psi or so, and you'll have a 13.0 (or so) 1/4 mile daily driver.. but with the push of a button (say, upping to 18psi), you'll be eating vipers :P .. And remember, this is with botn on parts, without opening the engine itself... cool, huh?

I talk too much, heh! ... Go with the MK4, you wont regret it.

To be honest I want a nice fast daily driver. I mean I plan on keeping it twin turbo'd just probably bigger turbo's/piping/intercooler etc. I dont know what it will take in these cars to have a 10 second car I'm guessing 550-600rwhp with a good driver?.

Anyone else?

My suggestion, go to Hondas site and pull up the NSX.



Costs more then(considerably), weighs more than(noticable), produces less power than(dramatically) a Corvette.



You can pull the cars up on Hondas site.


BTW, my info is about a month or two old.


I don't like the NSX platform. They.. don't do anything for me.

Hrm...
 

NeverFastEnough: When you said you wanted a "fast daily driver", I could've guessed many things, but.... you want a 10 sec daily driver? Lol, that's kinda funny.

Yes, I'm guessing you'll need over 600 hp @ the WHEELS at least, to get there... but I might not know what I'm talking about.

There is a guy in z32power.com with a 300ZX as a daily driver... he can do 11.something, I don't remember how many HP he has, but I think it was over the 600 @ the wheels.. he even made a custom made little fuel tank with race gas (high octane), and with the press of a switch, BOOM, the fuel is drawn from that tank instead of the normal fuel tank. Insane stuff. Wanna know the best part of it? He runs the STOCK wheels! Hah... 16" I think... with semi-slick tyres I think, Nitto or something, don't remember.

Want my honest opinion? Whoever drives a 10 sec car daily, is nutz! =P It takes a lot to reach those 10 secs. And it's just not HP... then you gotta make the car take off nicely from the line, coz you'll wheelspin like a madman. :P

Actuallly, TT's are generally more suitable to V-config engines (v6,v8,v10, etc.). The thing that makes the MKIV Supra's TT special is the fact that they run sequentially. Other than that one fact, there's no significant difference between the performance of two small turbos or one turbo twice the size on an inline-6 engine.
Sorry, there are no larger-than-stock TT's available from the factory. In fact, there are no sequential larger-than-stock TT's available from anyone.

The internals are already forged (or close enough). The generally-accepted reliable max on oem internals is 850rwhp through a 6spd (i.e. 1000hp at the crank). The 'record' single-dyno-pull on oem internals is near 1100rwhp (about 1300hp at the crank)

Yes ... in fact, over 1250rwhp (produced by 2jz-gte's with 'built' internals) has been repeatedly & reliably run at the dragstrip on through the oem 6spd and the oem diff. Iow, the entire 6spd driveline (other than the oem clutch) is rock-solid. The oem auto tranny isn't quite as beefy, and does need upgraded internals above about 500rwhp.

So I could even get the TT car and even just make it one big turbo. Turbo lag would then come into play obviously just don't know how much it would cause. This is all great info guys keep it coming, I dont even know if ill be comfortable in a supra but Im going to wait until my 97 Cobra is sold before I start looking. Its either this car or an 04 Cobra now which would be a great car but there are so many around here and Im starting to bore with them. I do understand the idea behind the sequential TT setup what I meant was that the car is setup TT'd from the factory so going with bigger turbo's wouldn't be that much of an undertaking. Sorry for the confusing post. Hell Id be happy with an 11 second daily driver and then I can turn it up to try for 10s on the weekends at the track. Something like that in my area would be a car no one would go after I know that. Mostly stock/slightly modded cars 12 sec+ and bad mouth'd drivers.

The driveline on this car seems almost limitless for what I want it for, but am I correct in saying the stock 2jz driveline differs greatly from the 2jz gte driveline?

If you converted to a single turbo, additional lag may not be as big an issue as you might think. Note that there have been some advances in turbocharger technology since mid-to-late '92 when the Mkiv Supra's oem twins were spec'd. For example, if you got a modern-day single turbo that was exactly twice the flow capacity of one of the oem twins, there would be more lag than with the oem twins operating in sequential mode, but less lag than the oem twins operating in parallel.

Unfortunately you're wrong there. The Mkiv Supra's oem twins are two very custom twins squeezed into a very tight configuration. Replacing them with a bigger pair while still preserving the sequential operation is just not feasible.

Yes. To be more precise, the 2jz-ge driveline differs greatly from the 2jz-gte driveline.

Cool man your really helping me out. Personally I didnt like the idea of the "sequential" anyways. Seems as if there would be a slight or even larger downtime where the boost drops for a bit then spools back up with the second one. What size are the stock turbo's on them now? I was thinking of going with a 60-70mm single and just keep the boodt at a low/moderate level for around 400 on the street which I used to do in my 89 mustang gt, and that was great. But come track time I want to turn it up a bit more to around 500+ if possible.

Toyota invested a LOT of resources to make the sequential transition as smooth as possible. There is a separate actuator for the prespool...and the oem fuel & timing curves have been extensively 'tweaked' too. Oh, and it doesn't spool back up with the second one after the transition...it spools back up with both.

CT12B's.

You don't need a 70mm turbo to make 500rwhp...a 60 would be fine.

Would a 60mm handle putting the car within 9 seconds of a 1/4 mile as long as the driving/rest of the car is supported with the proper equipment to handle the power.

No...not unless you're spraying LOTS and LOTS and LOTS of nos too...

I was under the assumption 650rwhp is good for at least high 10s with the right driving/all else. Arent the 60mm's from Hks/Greddy good for 750 max..or is that Flywheel max?

Your assumption is correct.

1) HKS/GReddy don't offer any 60mm turbo kits for the Mk4. Only the HKS GT wastegate is 60mm, coincidentally.
2) The smallest HKS turbo (T04R) and the smallest GReddy turbo (T78) are both about 67mm. They're good for about 675rwhp-700rwhp through a 6spd without cams, and about 725rwhp-775rwhp through a 6spd with cams.
