BoostFrenzy

I just bought a 2002 Z06 has AFR 205 heads, LG G5X4 cam, full exhaust, built driveline, 3.90 rearend, suspension, brakes, slicks, cage etc etc

is it fast? YEP

is it streetable... NO!

It made 475whp at finishline performance and you COULD street drive it, sparingly, but I took the FD to work and it's so much more civilized, if any of you guys are contemplating the swap, leave the engine primarily stock and boost or spray it, these engines are a bucket of **** all built naturally aspirated

I'm already selling it after 2 days of owning it, back to the drawing board for a civil 10 second car

"A bucket of ****"? Wow, haven't heard that one before Can you elaborate a little more on why it's no so streetable? Pretty cool you have both cars

xthephilx

The LS1 people...tend to not really give a **** about what is said about the swap here, so I'm not really sure where you're going with this.

How streetable would a 475whp 13b be anyway?

A 475rwhp z06 not streetable??

LOL

Sorry man but that was funny. I think maybe you're trying to complement us FD owners?

And please elaborate on how unstreetable that car is to you. Cause i think that was an opinionated comment.

my twin turbo 5.0 mustang was very streettable at over 650 to the wheels...that cam probably had a ridiculous lobe profile and was a thumper, and probably had a 2500-redline powerband, made for track, not street. yes you can make a v8 non-stretetable if you keep its efficiency in the upper rpms..for drag racing...( you did say it had slicks..so..im sure thats what it was meant for...

a moderate street cam with an idle -6500 operating rang and supports intake wtc. will make for a very streetable ls motor...a Z06 has an LS6 (new ones have the LS7), that makes about 450 stock at the crank. that's all you need, the cam can stay the same up to over 600 hp I'm sure. Intake, exhaust, heads/valvetrain maybe, ignition, and you'd be well over 500. a good tune up to 600 surely.

Atleast you have AFR heads, there should be an instant 100 hp increase over stock alone. AFR = best in the damn world.

a lot more streetable i would think. The LS1 would have mad torque and power everywhere, pretty much all the time. It would have that crazy N/A throttle response and probably a pretty wild idle. The 13b would be extremely civil unless under boost, and could idle perfectly fine with a streetport. off boost would be pretty much stock. Thats just the nature of turbo vs. n/a

475 RWHP is not some crazy 1200 RPM idling .650 lift engine in an LS1; I've ridden in much faster cars that are well within in the limits of what I consider streetable.

The "suspension, brakes, slicks, cage etc etc" is more likely to leave a car track-only then a simple 475 RWHP motor, assuming the tuner knows what the hell he is doing.

Then again, I suppose some people are pansies, so that could always be the case here.

DCrosby

I's ay the same thing someone said to me, when I posed the following question on an 800RWHP 13B FD

Response: Yes if I was to floor the gas and hold it down, ever heard of "Partial Throttle?"

My at the time dumbass response: I guess you have a point....

Just because you have an Enzo doesn't mean you have to drive i like an idiot up and down malibu, and claim a german national wrecked it for you.... most people that have those cars (weight /hp) know better...

NOPR

You certainly know more about Lsx motors than me, so I'll take your word for it. I've never even been an LS1 with that much power so i wouldnt know, but I've been in some big turbo 13b cars and I know they are perfectly fine driveability wise off boost.

Thanks, I needed a good laugh.

I'm not a huge fan of low torque motors, so I tend to gravitate towards positive displacement blowers (namely screw-type) but I do agree that a turbo car (this isn't really 13B specific) can maintain very nice street manners and still be explosive up top. Modern turbochargers and electronic boost controllers can do wonders to drivability, and artificial displacement can do wonders for horsepower.

edit: I'm not intending to imply that all turbo motors are low torque output; rather that I like to have massive torque right off idle. I tend to stick to tracks that are straight lines with a christmas tree, so they suit me well.

^ +1 for lysholm superchargers.

Sr20fd3st

was that meant in sarcasm or what? and on which part?

If I hadnt had experience building V8's I wouldn't make any of the statements I did.

There's also been 1000 HP+ streetable LSx motors. They are very tame, unless you build them improperly so it's just a lumpy thumpy valve seat destroying vapor locking piece of ****.

that LG cam is huge. why not swap it out for a milder one?
remove the side bars on the cage.
put cats in the exhaust.
that should make it more mellow for the street.
the pics you showed me of the hot yellow z06 look great. give it a shot.

Sr20fd3st

yea definately throw in a mild cam. what are the specs of the cams in there now? high lift with fast duration?

digitalsolo

iTrader: (2)

That just doesn't make sense. A very tame LSx isn't making 1000 HP+. I'm a huge LSx fan, but the simple fact is that no "tame" street car is making 1000 HP, it's not happening.

A big turbo car can be detuned to run on the street, and make 1000 HP when tuned up, but then it's not a 1000 HP street car, is it?

Sr20fd3st

by tame, i mena tame in the world of 1000hp cars. actualyl i think it was the guy who does all the fuel maps for GM. the head guy or whatever..saw it a while back. had a corvette and it was fully built with a blower, but it was streetable and pulled 1200 hp, was an ls6 motor. but then again thats from the leading fuel engineer or w/e at GM.

"Intake, exhaust, heads/valvetrain maybe, ignition, and you'd be well over 500. a good tune up to 600 surely."

"there should be an instant 100 hp increase over stock alone. AFR = best in the damn world."

Does horsepower fall free from the sky in your world?

jimlab

With enough cubic inches and forced induction, it's possible.

Let me fix that for you

The only thing uncivilized about my LS1 is the low end...skating sideways after taking off through 1st and 2nd scares the children

Pat McGroin

Driveability is dependant on what a person thinks is streetable or not streetable, it's different for eveyone.

Heck, you have guys in Australia street driving 540whp LS1 cars NA! Maybe it needs a better tune or some ITBs.

Sr20fd3st

fine then goto afr and see what happens when you bolt a set of their heads on a stock mustang = 100hp over stock instantly.

oh yea what happens when you put those heads on an ls6 with 450 hp along with a full exhaust, upgraded igiition system, fuel, intake, and a good tune? easy 600. come on it's not that hard to grasp.
my 5.0 mustang turbo was smackin 650 hp and 750 torque at the wheels.
it was a full build from a bare block and blow-through carbureted with 9:1 compression. that setup with a highly tuned EFI system would have put down much larger numbers. There is nothing unreasonable about stating an ls6 motor with bolt ons and a proffesional tune would put out 600 HP comeon...

Sr20fd3st

now see, that ls1 just dropped 540, and your saying an ls6 cant? christ...

jimlab

Doesn't matter, since we're not talking about Mustangs.

Really? Then why isn't everyone doing it?

Good for you. Once again, we're not talking about Mustangs, turbocharged or otherwise.

Only if you can't tune a carb for ****.

Unless you've been buried under a rock for the last 10-15 years, you should know that EFI and carbs make about the same maximum power when properly tuned, all other factors being equal. The only real difference is fuel economy and drivability in climate extremes.

Reality says otherwise.

Reading isn't one of your strong points, is it. Since when do bolt-on LS1s or LS6s displace 412 CID?
