Just playing around without trying, we got around 5 seconds... With 4 seconds of that being an extended burnout.

look in the videos section.

I've casually ran it against a 2002 Z06, and If for some strange reason the SC300 can hook up, its neck and neck 0-60 with Z06, which puts it at low 4s. Jeff has a 6spd and LSD in his SC300 and he said it easily keeps up with any LS1 off the line, which is pretty good. Of course after you hit 2nd gear in the SC, those little things like Z06s fall into the rearview mirror pretty quickly.

Overall though, unless you have the LSD or drag radials (at the track or steet), you'll probably give up a small lead to the average Z06 in the first two or three seconds.

 

Scott, only problem is my car is an auto, the conversion can still be done though....correct?

 

Yeah LSD swap can still be done

Though I'm not sure if the ratios will be similar

I've been thinking of getting the LSD from the Supra N/A for now until I do the 6-speed tranny swap... just to keep the mph correct on the speedo

is there a way to fix the error that will show up on the speedometer?

 

How much (safe) rwhp can you pull out of the state 1.5??

 

stage 1.5 will get ya over 400rwhp...Jeff

 

so this would be better than putting a turbo on an IS. I dont know of any kit around that price that will pull that much hp out of an IS. I mean, for 6-7.5 i can get a turbo (so they say) from PHR that will pull about 320-350 rwhp. Thats still not as good as the one for the SC though! I thought the SC300's tranny would only hold 400??

I know that I am probably wrong, im just curious! Thanks for the info!

 

My 5spd has withstood well over 400rwhp in a constant basis and over 500rwhp when on race gas... I don't pop the clutch, I don't shift hard and I don't run slicks or Drag Radials, though... If you're hard on the tranny at this level, it will not last. If you're gentle, it will last for quite a while... My 60ft time at the strip (2.2-2.3) reflects very gentle launches and very limited traction from the all-season tires and open diff.

PHR does very good work as well, and their kit will make as much HP as the Toyomoto kit with the same turbo. I'm sure PHR is being conservative when they quote 350rwhp. Toyomoto quoted 330-360rwhp with the 1.5 kit that I got, and it actually does the 360rwhp that they quoted if you turn the boost controller off and just allow it to run 9psi... I got the AVC-R with RPM dependent boost control and dialed in a little extra on the top end (above 5500rpm) hence the 423rwhp. Those runs were on pump gas. I think 400rwhp is possible at 10psi with dead-on air/fuel ratios and optimized ignition timing. With an extra 6psi and race gas on my runs you'd add another 75-100rwhp to the 423.

 

How do you think a 350 rwhp IS300 would hang with a 400rwhp sc300. Do you think the weight would make that much difference??

 

This is not true. The HKS stainless manifold is WELL over $1200 for the TT.

Here is a link to typical pricing on it...

http://www.suprastore.com/hksexmant0st.html

The SP Manifold is $2600 and comes with your HKS GT Spec Wastegate, Manifold, and high temp coating, and a 3" shorty downpipe!

From most places on the internet just the manifold/wastegate is @$2200. This does not include coating, so for $2600 you get the manifold, modified to fit our motors, 3" downpipe, and high temp coating. Also, mine was the only one to my knowledge that you had to modify the throttle body because mine was the first. They have changed it slightly since then so that the turbo sits slightly lower and closer to the motor so you don't have to do that at all.

Once again, I am not saying the toyomoto kit is not quality, I am just saying that if you have the time and know how you could put together a MUCH nicer kit for the same money. You base it on there manifold, and add nicer pieces that what they give you. I honestly don't even see how it is questionable.

I also meant to ask...how much hp will the 2jz-ge engine hold???

 

ethan...im not bashing sp at all..they make great products....but all companies have to make some money to survive...toyomoto kit isnt a rip off.....and is fairly priced and has been the same price for YEARS......and i dont think anyone could put together a "MUCH" better kit......i think the kit is top of the line..and has proven its worth and reliability......for years and on many cars.....Jeff

 

a 350rwhp IS3 wouldn't hang with a 400rwhp SC3... it'd be almost as fast, but still far from even

the 2jz-ge is said to handle about 700-800rwhp before it needs to be built vs the 2jz-gte's 1000rwhp

 

Thanks...im just trying to see what my best bet is going to be. I love the way the IS's look, but for the money, you get more hp out of the SC's.....im confused

 

remember IS3s have a lot more emissions equipment junk on them than 92-97 SCs do

thats the bulk of the problem right there

 

I will still probably go with the IS. Just because I need a little more room. All I really have to do is swap the tranny for more hp. Which that is 9k that I don't have right now, but I am pretty sure that 350 rwhp will get me around right now I will just have to see what the future holds i guess
