where is ur turbo setup from?
i beleiver im going the sp route after talking w/ larry the owner he really knows his stuff, and very specific to our cars sc300


anyone going to NHRA @budds creek? im reallly trying to have my car ready for it, at least the engine ill worry about my stereo later

 

Computerwiz... I'd go to Toyomoto for the exhaust manifold, downpipe, and intercooler and intake plumbing. You can source the stock TT intercooler, ABV, and TT fuel pump your self. You can also spec out the turbo yourself and save here. I forget which flange type you need on the turbo, it may be tangential or centered, forget which. You'll need braided steel hose for oil feed + appropriate Aeroquip fittings, plus you'll need a length of reinforced hose and fittings to tap into the stock fuel lines. The oil drain hose needs to be pretty large diameter with fittings on both ends, and you'll need to drill out a boss in the lower block of the engine. (not as big a deal as it seems, although you have to move the oil pan to one side, this is a PITA). You'll also need a REBIC or Haltech injection controller, a boost gauge and A/F or EGT setup. The manifold takes a standard Turbonetics Delta gate external wastegate, and I'd start with a 6 pound spring and then move up to a 10 pound spring. On the turbo, if you're staying with lower boost and stock compression like me, you'll need a turbo that thrives on low boost. This would be a T60-1 or an SP60. You could probably run a T62, but may not make any more power at low boost (may even make less). At this point the Ball bearing option is not needed, but ceramic coating and tuff turbo options with larger shaft is recommeded. If you go with a 60-1, I'd recommend .58 A/R and P trim compressor wheel. Mine has 0 trim, which is great for spoolup, but I'd like more top end out of her.

I'm probably forgetting something here... This is just off the top of my head.

!!!!!NICE EMAIL ADDRESS!!!!

 

Now if only he would return my e-mails.... Any ideas on how much those parts will run me?

SR

 

What I'm saying....is that if I can get all the parts I need, for $4k or less, I'll but them now! I figure about that is what it's going to cost me to build a custom supercharger kit, and I would rather have a tried-and-true product for the same price.

Forgot to mention.....after seeing the Bomex kit on a couple other cars, now I'm not so sure if I want to put it on....I would have some major ground clearance problems when I go to slam my car. Anyone want a Bomex kit? lol

SR

 

Lance never answers e-mails.
You'll have to call him up.
He doesn't answer the phone, either, so you'll have to act like you know him on the phone, otherwise the person that answers will say he's not there. You can get plenty of info from whoever is there, though. Just keep calling until you get a live body. They're all fairly knowledgeable.

 

i think you should spend your money on the toyomoto kit and BPU's... the interior/stereo/kit can wait...

 

LOL. A S/C on a 2JZ? LOL. If you know so much about cars and super chargers just get a turbo from SoundPerformance and put it on your car yourself. Super chargers are wimpy. Especally on a iron block engine. Super Charger on a civic causes little HP increase but thanks to the weight of the car that's all they need! You have a hevy iron block engine. Turbo will do more for you and will be as reliabile.

I remember a post on supraforums.com about some guy wanting to supercharge his N/A supra. He's been poked on because of that post ever since.

 

hey SC300T I'm a future owner of a SC300 and I'm 100% sure that I want a turbo... but I want a decent one...

I see in your sig that you're running a T60-1... I've heard several references of that particular turbo before... is that a T04E w/ a 60-1 compressor wheel? or a full T60 turbo?

My goal is to run a ~120mph trap speed without NOS...
I'm not really sure what kind of power that would be on a 3600lb SC300... but I'm pretty sure its possible...

Does toyomoto sell more than just a T04E-flanged manifold? like a T60-flanged manifold?

and one last question I have after all my reading of these forums...
What is keeping people from running higher boost? I know the 2jz-ge can take more power than a measley 400rwhp... is it because of the 10.0:1 compression level? too much heat from a smaller intercooler? not enough fuel? too much timing?

thx

Huh? If I know so much about cars and superchargers then WHY in the hell would I get a turbo? That doen't make much sense to me....

***** anytime you see "SC" in this post, I'm talking about SuperCharger....not the Lexus SC. *****

I don't want a turbo. I don't want the problems of a turbo, I've had both turbo and SC cars before. I like the ease of installation of the SC. No oil lines to run from the block, no tapping of the oil pan, no modification to the exhaust and cramming lots more of high-temp. stuff in the engine bay. There's no way you can tell me that one of those turbos is going to last 100k miles under hard driving. I've seen SC's do this.

Iron block? What in the hell does the make of the block have to do with the type of forced induction?! 8psi with the same intake temp is the same, wheather it's turbo or SC. Intake temp is the key. Most people that put on SC's don't do any type of cooling to the air. Most everyone with a turbo does. This makes a HUGE difference. Imagine having your turbo kit on, but without the intercooler. That's the setup most of these SC's have. If a turbo with 10psi and intake temp of 150deg adds 150hp, then a SC with the same stats will also add 150hp. The only difference there is the SC will be pulling some HP off of the crank, lets say 10 - 15hp. So true, at the wheels, the SC will be making 10hp or so less, but I will take that tradeoff to the turbo issues.

I'll for sure have an intercooler on it, or maybe put an air-to-water aftercooler on the thing, which will GREATLY reduce the intake temp. Then I'll be able to raise boost to what I want, and get the power I want.

Plus I'll be doing all of this for under $3k....even cheaper than the F-Max kit.

SR

 

Heh. A good turbo setup won't give you any of these problems. We'll have to race when I get a turbo on my car.

 

I think a supercharger of the size you're talking about to run 10psi is going to be generating more heat than the turbo... wouldn't it?

I don't know what kind of bad luck you've had with turbo cars but I know of plenty of turbo cars that have LOTS of miles on them...

plenty of SupraTTs, 300zxTTs, RX7s (even with their detonation-sensitive engine), VR4/TT Stealths, etc
Buick GNs, SVO Mustangs, Turbo T-birds, etc

all of these cars are very very long lasting with a turbo (with exception of the RX7, but mainly it being detonation-sensitive; and the engine costs $1000 to rebuild and is easy as hell to replace)

I don't know of many supercharged cars that last a really long time from Japan except the MR-2 Supercharged... other than that; the performance-minded supercharged cars in Japan are almost nonexistant because they use a turbo instead... why do you think that is?

Its your choice though
If you want low-end grunt thats cool; but a supercharger of any type reeks on top end; which is a turbo's favorite spot...

You know why there are no turbo cars in Top fuel right?
when they were first making it; they made 5x the amount of power with 3/4 the size of the engine and only a 20% mix of nitromethane instead of the 100% mix they were running in the supercharged cars... there wasn't a drivetrain that could hold it; and before they found one; NHRA banned turbos from the top-fuel cars because of the ridiculous amounts of power they were making...

that may be a bit over of what you wanted to do; but turbos are so much more efficient with their boost levels... to get a supercharger to run 10psi and make 400rwhp on a previously 160rwhp car; thats 240rwhp more; not 150rwhp, you'll need a huge supercharger and definitely require an aftercooler... not to mention the turbo can make a lot more power by giving more fuel and simply turning a ****... i know for a fact that if i built a 400rwhp Lexus that it wouldn't be enough for me after about 3-4 months of driving it; i'd want more...

you're deluding yourself if you think you can build a SC kit that will make as much power as a turbo kit built for the same price.. i don't mean to sound like an ******* but its pure and simple truth on these cars... if there was no turbo manifold readily available or anything then it would be different...

 

btw, why did @home close port 80 on your cable modem? thats fucked up man...

i never had any trouble with them for my website

 

LOL...
Computerwiz --- Ahhh...You have so much to learn.

I'm assuming you're talking about a centrifugal supercharger... Your 10psi will give you a PEAK of 10psi at max revs. What do you get at say 3k rpm? 3psi? How about 4000rpm? 4-5psi? These thing have NO POWER under the curve, and are just good for a top end spike.

Let's say I set mine at 10psi... What do I get at 2000rpm? 3psi. 2500rpm? 8psi. 3000-7000rpm? 10psi.

You set yours at 10psi, and I'll set mine at 10psi. Any wagers on performance potential?

Lets say you want to go to the track and whoop some ***... I dial up the boost and add race gas... Can you do that? No way.


Turbo 2JZs go 100k ALL THE TIME!!!
I've put over 35k on my 130k engine with absolutely no problems whatsoever.

 

every person says the same thing....let's see what happens when I get my turbo....i'll race you with my turbo. Just so y'all know....I DON'T CARE. I'm tuning the car the way I want, for my style of driving. I'm not planning to make it a "race" car, rather much the opposite. It's all daily driver, with some added race qualities. Everyone talks about how you don't notice the turbo-lag, etc. Well once you've driven SC'ed cars you can tell the difference in throttle response between the turbo/SC.

I've already agreed that the turbo would be a better application if I was going for all out power/quarter times. I want power for daily driveability...lower RPM power....no spool up time....etc. If you haven't driven a SC'ed car, go drive a Jag XJR. You'll see what I mean. You feel the power INSTANTLY.

SR

(flame away...lol)

 

Yeah but power instantly isn't all that great; i think instant power can be a problem without a limited slip rearend... if you're up in the revs you will feel the power instantly and traction will be less of an issue (although still there due to no LSD)

as for daily drivability; a turbo car making the power you're talking about will be more reliable than a SC car and also get better gas mileage... the engine will also last longer because overall there's less stress on it
