These days the cars are becoming suprisingly faster. With turbos and just technology always improving.

But one of the top dogs on the streets in my opinion is the LS1. Even in its stock form these cars i still to can't seem catch. They have the top end power to make them just fade away from me.

Some of you L98/ LT1 guys on this board must be able to bully on these LS1(stock or mild mod) cars. So what does it take?

Another question... What would it take to make a L98/ or LT1 be on PAR with these cars...(firebird/camaro/corvette).

Its still fun getting my A$$ kicked buy these awsome cars! But pulling sleeper would be the Best!

 

your extremely limited by the intake on the TPI system if u are dead set on keeping a gen 1 sbc in your ride then a aftermarket intake setup is a must to let the car breathe over 4500rpm...now on the street tq is king and a good l98 with a decent cam , exhaust and intake setup should do good against an LS1 street light to street light...but there is far more potential in the ls engine and all it takes is a cam swap and hes once again out of your league. if u want to start throwing money into your l98 im not saying its not a wise investment but the wisest thing to do would be to sit down and make a pros and cons chart of a built up l98 vs maybe an ls motor swap. there will be plenty of guys pop in to expand more on makeing power with the l98. i just didnt want the cost involved and decided for me id take another route. good luck

 

I see what your saying. With the cam swap in the ls1. I have replaced the old tpi for a hsr. So im guessing im a heads and cam away from pulling on one of these cars. But on the other hand long term it would be nice to plan a Ls1 build. Im always interested in buying a wrecked 4th gen for interior, drivetrain...But i would most likley maintain the hsr and build a well balanced stout motor. Im a little intimadated with the idea of a swap. The fabrication, computer. But if i was to take this idea on, it would not be a stock ls1. Now that would be the best. And it would open a whole new world with aftermarket speed parts always being developed. Interesting idea...

 

When you had your stealth ram installed did you have your car tunned?

 

Yes i had to have my car tuned.
Installed the intake with stock tb. injectors and got the adjustible fuel regulator. Put it on the dyno ran like **** with no bottom end. Made copys of my 3 runs. After the shop i sent PCMforless all my dyno sheets along with other information about my car. Then they sent me a custom chip and it worked great... my fans even come on a little sooner and i recovered my torque.

 

Im planing a gear swap from 3:08 to 3:73. So from a dig im hoping to get a jump on these cars and hopefully it will be a bitch to catch me.

Does anyone have any et. # compairing a gear swap. Tryed to search did not find what i was looking for.

 

Heads, cam, exhaust and a little intake work we get 360-380 to the rear wheels with TPI and blow the LSX cars away.

Not to take anything away from them, but we are just bringing the tech. up on our stuff to match what they get stock.

 

Mod for mod, it's hard to compete. I own both, and they are two very different animals. Even though it's much slower, I still enjoy the low end grunt of my 91'. It's a great daily driver. The 2000 ran decent stock, and got awesome gas mileage. I never intended for the car to become what it is today, but it just kind of snowballed over the years.

Basically, I would say make your car hook and leave hard. And don't run an LS1 car from a roll. If you can get your car to leave violent - you'll shake up a lot of people with faster cars. And many of them won't be able to recover. Most of all, build the car to make yourself happy. I've always been told by my father, "There is always someone who wants to beat you, and someone who eventually will."

 

3.08 =8.742 to 3.73=8.604 in 1/8

 

no surprise given you have a stock cam and heads.

I am very close to stock LS1 6 speed but my exhaust is junk and I think I need better tuning.

I want the BBK intake to move up the next level.

 

Spent some time on LS1.com and most of these cars from factory run as good as 13:3/13:4 and Dyno around 280rwhp/ 305rwph some more some less.

I have raced a 2000 z28 auto from a dead stop total stranger (later said it was stock) we both left hard, it was dead even till mid way through 2ed gear. Then the top end of the camaro started to shine! I think gears will be a short term solution to make a great head to head race!

I will eventually build a 383 using AFR 195s 1.6rr, my current intake, as for the cam undecided... 112/.525/.525 unsure about the duration at this point.
Just a nice street motor with usable power (370rwhp)??? And a good shot of juice like 175 for the track. With all the supporting mods...

 

Gears yes, and a converter as well. Shift extension is where it's at. My 2000 bone stock ran a best of 13.46 @ 104 MPH bone stock, 26K miles. Gears weren't even worth a full tenth for me - 2.73 -> 3.42's. However, tires/converter/tune netted me .9 and 3.5 MPH. I picked up 24.5 peak from a basic bolt on tune. Most of the ET reduction was due to the converter and drag radials. Full bolt ons with an N20 tune was good for 12.20's NA in the summer heat. I can't stress enough how important a good converter is. Right now it would wake your car up even with your current gearing.

Just my worth brotha.

 

I need to go to the transmition shop in the spring anyway. To flush the tranny/ gear swap/ so ill ask about a converter...

Would a 3000-3200 stall work well with my current set up as well as a built 383 in the future(street friendly)? I dont mind spending money on this, but if i will grow out of it i would rather wait.

What brand and how much?(gears and a converter would be a blast!)

 

my daily driver is a 383 . Very street friendly. You just leave everyone from the stop light lol.

 

I think a 3000-3200 would work for now with what you've got, and you'll grow into it with the new set up. I would go with an FTI, long known in the racing world - comming into their own in the street car market. Dollar for dollar, a converter is about the best bang for your buck short of nitrous.

BTW - I have a 4400 stall in my 2000, it is my current DD. So anthything smaller seems VERY mild to me. A 4400 sounds insane to most people, but the car drives great. No complaints here at all.

 

There is no replacement for displacment and tuning your suspension so all the power gets to the street. Then you kill them out of the hole and wave goodbye.

 

if i were to use the foot break to load the 3200 stall what rpm might the car be able to hold just before the tires break loose. Sorry for the stupid questions. Also what is a fair price or how many hours in the transmission shop would it be for a converter swap??Thanks for all the advice, you guys have some serious machines!

 

Gears should DEF get more than just a tenth, even in teh 1/8. More than likely it was traction limited, or driver error. I know when I went from 2.73s to 3.73s (5.0) and 3.23s to 4.10s (Cobra), it took a long time to get used to launching with the new setup, because it is a lot more torque at the wheels once you release that clutch/transbrake. Shaved ~0.5 to 0.75 on each car, not too mention the streetability is much better. Gas mileage also increased, except on the highway since I'm sitting at ~3k at 80 mph in 5th gear, on each car.

If you're going to have the trans out anyways, you might want to see about changing the gear ratio for 1st to make it a little easier on the tires. When I blew the T5 in the fox, I had it rebuilt w/ a 2.95 1st, vs. the 3.27 it comes w/ from the factory.

 

LOL so true....aka or "There's always someone bigger and badder than you"
also from my father

 

For lt1 cars all it takes is a a bit of bolt ons and then they can take a "stock" ls1, but again if the ls1 gets modded then its not much a chance.

 

I've still got 3.27 gears, stock TPI from the TB to the base (be it ported by me), stock heads, stock cam, stock bottom end, high miles; I have beat TONS of LS1 cars in the 1/4. My car runs 13.4 at 101 on motor, most of the LS1's at Edgewater in Ohio are high to mid 13's. There are some 12 second runners, and a few nitrous guys but on spray my car does 12.2. The biggest thing for me was weight reduction and tires. I'll be really rolling on them when the stealth ram Vortec engine goes in. Trust me being the guy with a stock TPI engine doing 13.4's has its perks over being the guy in the 2000 Trans Am running the same times, people usually think I'm spraying it until I pull a spray run on them and the jaws really drop. Aside from the tires, suspension, and weight reduction I also swapped the 700R4 for a TH350 and a 3000rpm stall, TPI's don't like a ton of converter, they build monster torque so 3500 down should suite you well.

 

Its gona be like beating my older brother in an arm wresle!
Just to see the look on his face.
