When your car is done i would love to go for a ride to see how fast it is compared to my slow lex .

Take it from a guy who owns fast cars and just bought a 93SC300 slow mobile. My Supra would run circles around the SC300.

 

Sure no problem, although I am building up the 2JZGE platform to see how far I can go with it. I did at first opt to do a complete engine swap with the GTE but decided to lower compression with 3mm MHG and ARP studs and put the BG63 on it and 3 row FMIC with 720 HKS inj and fuel rail. I do believe this setup is going to crush some serious but. Only if this car was a bit lighter. I may end up taking out the back seats also. But again in stock form a SC300 is no speed freak. Any car can be made to run fast, its all about how much you willing to spend. A T78 is a very nice setup provided you ahve the rpm's to go with it. That was my first choice, but decided to go with quicker spooling.

 

First of all, an SC400 is not slow. 0-60 in 6.9 is nothing to be ashamed of, and it can be made much faster easily. "Anything slower than 5.0 seconds 0-60 is slow" are you kidding me?! Like 2% of cars come even close to that!!

 

However, yes, camrys are pretty slow, but they were never meant to be fast. Remember that if a car does 0-60 in 8 seconds or less it can be classified as a sports car. As far as luxury goes, it must have a certain number of features and have a base price of $35,000. (This is 1992 stats i speak of.) Keeping this in mind, an SC400 is both luxury and sports, but a little more luxury than the sports, its true.

 

Just a note - taking out the back seats won't save you much as they're mostly foam. The bigger savings would be getting rid of the front seats (they're HEAVY!!!) But then, you lose a lot of the luxury that's a Lex...

 

okay if u guys think that a camry doing 7.1s from 0-60 is coool. check this out!! a stock is300 does a 13.7, its a sedan luxury and a v-6 and ties the ls1!! man i wish i could trade in for one of those!!! does anyone know how THAT is possible.





BIG ONKER


ps- lexus rules!

 

We cleared up that camry doing 0-60 in 7.1 seconds... it was all a falacy and could never really happen. as for an IS300 runnign 13.7 stock, thats also impossible. They run about 15 stock. Drag racing isnt really where the IS does best, but in the autocross they tear $hit up, capable of twists and turns that would put most SCs to shame.

 

Doesn't your supra weigh 3500lbs too?
Ive seen some nasty sc300's that would tear up a supra (stock)..

 

I took my car to a dyno yesterday, and MAN these cars are SLOW.....

First of all, I'm in Colorado, so I have a 5500 foot altitude detriment, but check this out...

Corrected HP is 152, and torque of 150

ACTUAL HP is only 125, with torque of 123.

Holy crap, but a honda could take me at this point. The car runs perfectly, no missing, no hesitation, and the air/fuel ratio was excellent on the wideband o2 they were using, so no problems there.

Now, the reason I did this, was to get a baseline on the car, for when the turbo kit goes on in a month.

Today (If it doesn't rain) I'll be taking it to Bandimere speedway to see what 1/4 mile time I can get out of it.. I'm betting 17's to 18's.. sheesh.. (18.79 is the estimated 1/4 mile time at this site... http://www.fantasycars.com/derek/quartmile.html)

But, on the other hand, it will be EASY to double my horsepower at this point, eh? And then it estimates I'll be able to run a 13.3 in the 1/4 at 350 horsepower. Should be interesting.

 

Guys I am a new owner of a SC300 so don't get me wrong , i am not bashing the 300, heck I love the car as a matter of fact, but I also know the true potential this car has in stock form. The car is just but slow stock. Now this is my personal opinion so don't hate me for it. The SC400 is also slow to me, but again these are cars built to cruise instead of tear up the 1/4, so they are excellant cars to own, and the potential for more power is there no doubt. I have been blessed to own both a SC300 and a MKIV TT 6spd. Both cars are great but very different when comparing performance. The Supra out of the box is a true sports car. The SC300 must be bulit up to go fast, this is all I am saying. Once I am done with my 300 I do hope it break into the 550 range. My goal is 550rwhp and 500+ torque. The 2JZ is proven to be one solid power plant.

 

SC300 doing a 17-18 1/4? NO WAY!!! The SC300 non turbo completely stock with automatic could do it in 15.8 no problem, SC400 in 15 seconds flat, so give yerself some credit man!! My freinds stock civic hatchback 106 hp NON-vtec inline 4 could do it in 17.2, are you saying you cant beat that?

 

Yes, I'm saying I cannot beat that, as a matter of fact, I made 4 runs. 18.5@76mph, 18.4@77, 18.3@77 were the first and best 3 runs. No wheelspin, traction control turned off (Although it wouldn't have made a diff).

First off, figure on missing out on 1 second simply because of altitude.. That means a 17.3 best chance at sea level.

Second, this torque converter is KILLING me.. Damn, I was getting 2.8 60' times on every run.. No wheelspin, just no guts till I was about 20 ' out of the hole. Looks like I'll be getting a bit of stall speed goin' on... I'm thinking something along the lines of 2800 stall.. Maby 3000.

Oh my god.. I hit the scales after my first run, and with me in the car, weigh's in at 3800 even.. (I weigh 175) Holy crap that's nuts! I refuse to remove items from the car strictly to lighten it up. I wanna run high 12's fully loaded, and with the 2jz, it can totally happen.

Another thing, would be to get a supra rear end with posi, for when I do double my horsepower, as I'll be roasting a tire and still slow at that point.

Finally, if you think my slow times, are my fault, I've won 4 drag racing trophies, in heads up racing with my Eagle Talon, which I ran for about 3 years.. A first place quick-8 in Oklahoma in 1998, a runner up in the 12 second class brackets at the same race (I hate bracket racing.. It has NOTHING to do with drag racing) A 2nd place heads up in the Street-8 in Bandimere in 98 also.. 2nd place at the DSM shootout in Norwalk, OH in 97 in the eliminator class.. I have about 150 low 12 second run tickets at racetracks from Denver Colorado, Oklahoma, Ohio, Florida, etc... I know how to race, so just wait to see what happens when I get the turbo on.. I expect to knock off 5 seconds right off the top, and we will see from there.

 

Knocking 5 seconds off your 1/4 time will be an arduous task at the least. Do you realize a second in the quarter mile is an absolute eternity? I still cant for the life of me figure out why the hell your car is going so slow... it must need a tune up or something, an SC300 doing the quarter mile in 3 seconds longer than it originally did must have something critically wrong with it.....

I'll be racing my SC400 soon... its strong and fast, I'm hoping for a nice mid-15.... one I get the ECu rebuild from lexuspros.com I'll hope for a nice high-14, and that'll be all I plan on doing for perfromance, for a while anyway. My freind with the 92 civic hatchback already put down a $500 bet on me.... but he plans on getting a vtec head and single turbo... I bet I could still take him if I remained stock....

 

Well, my car dyno'ed at 152 corrected HP. That means that my 18.3 was pretty much right in line with what the horsepower estimates suggest.

Its actually pretty easy to knock 5 seconds off of a car's 1/4 mile time. It only takes 3 things... 1. horsepower/ torque, 2. traction. 3. money

I will be running a T61 or so, which has 600 hp potential. With the thicker head gasket the car is getting, 400 to 500 HP will be a relatively easy thing to gain. That is the horsepower part. A 2800 stall torque converter will be going in, creating the torque part.

I'll be putting a Supra TT rear end on the car, so posi will apply power to 2 rear wheels. I'll have a pair of Supra TT rear wheels on, with 285/40/17 drag radials, so traction will be much better.

I'll be putting approx $6000 into the car over the next 3 months, so the money is available.

Going back to the horsepower calculator, a 3800 lb car, with 400 HP will run a 13.1 1/4, thereby knocking 5 seconds off the 1/4 mile time.

I also am suprised that the car is as slow as it is in current form, but I have 2 1995 SC300's, and the one I took to the track is marginally faster than the other one, so that tells me the car is suffering the standard mile high atmosphere sickness that all cars up here do.

 

When I say taking time off yoru 1/4 mile time being difficult, I take into consideration... the dragon tque converter realistically only removes 0.3 seconds from you 0-60 times, and 0.35 from your 1/4.... thats it. Those are the actual numbers, you'll never even get a half second from it... the onyl thing it improves is launching, so anything beyond about 10 mph will not improve. The Lexuspros full ecu upgrade with timing and fuel mixture is more worthwhile.... about a half second or more 0-60 and close to 0.75 -1 second 1/4. And this upgrade adds more punch to all speeds, not just launching. So consider the ecu costs 1200.00, the TC costs 900 plus install anywhere from 300-700, and you shaved a full second off your quarter for about $2500.00. You could throw in a catback exhaust for an extra 500, though I dont think its that much of an increase. I dont feel its worth spending that much money, three thousand dollars isnt really pocket money. Modding can be tough, I just went the easy route and bought a car thats already fast, and just want to do one or two things to make it remain competitive with my primary adversaries, which at this point seem to be turboed integras and 3.2 TLs!!
