ya i agree.....

 

Maybe I didn't make myself clear enough! I have a 97 WS6 that I'm thinking of selling. I know I can get pretty decent money for it and I will be looking to get a 2000-2002 WS6. Now, I've heard some people say that LT1's have better low end but don't they fall flat on their faces after like 5500rpm? What RPM do LS1's pull to? The first mods I'd do to a LS1 would be FLP longtubes, cat-back(probably Borla or loudmouth), and a high flow air box(not sure what's best?). Now with those mods and possibly a new MAF, what kinda power and times am I looking at? Thanks again on helping me out!

A stock LT1 will fall flat at around 5500rpm, but put a good cam and you'll pull up into the upper 6000rpm range. Personally, since I got to pay off my car, I was considering doing an engine rebuild, but that's $2000 right there, I also wanted to swap in an M6, there's another $1700 for the tranny swap. So I said **** it and just get a 01-02 LS1 pull out with an M6 for $500 more, BMR K member, fuel tank, Hotcam kit, Global West front suspension, MAC headers, which are $600 cheaper than the AS&M and Random Tech setup I was gonna get. For about $1000 more total, I'll make an additional 50hp than my rebuild, and save around 160lbs on the front end including the Baer brake kit. I can also sell my LT1 setup for another $2000 and get those 17x9's and 17x11 with Michelin Pilot Sports I've been eyeing... damnit! PATIENCE IS NOT ONE OF MY VIRTUES...

CDN WS6...

I have headers, Lid, MAF & a couple of the free-type mods done.

I have my rev limiter set at 6500rpm. It's still pulling strong when I hit the limiter in 1st & 2nd (real easy to do).

Now, I know that the LS1 rod bolts & push rods don't typically like to do this regularly..... but everything else DOES!

The typical bolt on mods you suggested, especially with headers... should put you in the 12s easy.

You may want to concider these headers too.....



Good luck,

trader!! j/k, i test drove a 98 WS6 and could only tell a difference up high. i didnt trade in because they lack the low end grunt that the LT1's have IMO. but, it is your decesion, i would test drive on.

 

I just believe that a well built LT1 will take more boost and abuse than a LS1. The LS1 will very well be more friendly to boost than a LT1 when both are stock. The main reason I think that the LT1 will take more boost/abuse is because of the block. LS1 is aluminum, the LT1 block is iron, is it not? Anyone else comment?


CND WS6: I say you might as well sell the LT1 and jump on the LS1 bandwagon. I imagine I will be doing so in a years time.

 

Aluminium disapates(sp?) heat better than cast iron does, thus the LS1 should be better overall.

 

But aluminum is weaker than iron. Why else do some LS1 guys take the 6.0 litre engine out of a 3/4 ton chev and use the iron block it has to make a wicked twin turbo camaro/ta? I'm not saying everyone does it but i have seen a couple (one in the for sale forum awhile back). Just something to think about.

 

I have ī95Z and a ī00Z both are A4 w/323 and stock except for cat-backs. It is true that the LT1 has more low end grunt, but it doesnīt do much for you other than spin the tires and the LS1 can do that all day anyway if that is what you are after. But itīs in higher RPMīs that the LS1 shines and itīs not just the extra 5-600 RPMīs after the LT1 runs out of breath. The LS1 just pulls much harder from at least 3000. Sure the LT1 can be built to be fast but so can the LS1. For a basic bolt on car or even cam or cam/heads, the LS1 is going to be faster. How many cam only LT1 cars are puting down over 400 rwhp?

 

As I explained earlier, the LT1 is better for forced induction because the iron block is stronger and adds strength to the heads bolt seating as well the crank main bolts. The LS1 needs six-bolt mains to almost equal the strength of the LT1's four. I also agree with the use of a 6.0 litre truck block for a forced induction LS1.

 

Most turbo'd engine blocks are made out of iron. Look at the 3.0 Supra I6. They can make 900 RWHP on a stock block.

 

I bought my LT1 car last year before I really knew much about these late model Camaro's, I wasn't even looking at them when I found mine. When I did start learning, I regretted not getting an LS1 car, but my car only has 31K miles now and I don't think it's worth it to sell mine and take the loss. For my purposes (mild bolt-ons) the LS1 would have been a better choice, but the LT1 is still an exciting powerplant. I'd like to retire the Z from daily driver and do a 383 kit with heads/cam. LT1's ain't all bad! You'll just have to decide if paying to upgrade to LS1 is worth it to you.

 

The F-body LT1 has 2 bolt mains and the Corvette LT1 has 4. On the LS1 both the F-body and the Corvette have 6. I donīt know how the LS1 compares to the LT1 strength wise but I dobt that the LS1 is much weaker since GM takes considerably more power out of it. Aluminum blocks can be just as strong as steel it just depends on the design and aluminum is stronger than steel per #

 

Well, money is the true judge of how fast you want to go. To say modded LS1 beats modded LT1, not true.

Now if I had to do it again, I would have went LS1. But when I bought my car over 3 years ago, it was a great deal and I had seen LS1's at the track and they were running 14's. Maybe Ohio had a bad batch?

Now I want to keep my LT1 just to race guys in LS1's because most LS1 guys are very cocky, and that sorta pisses me off. I help out at my local dyno shop and every LS1 guy that comes in expects big #'s(same at track also)...well, only on the internet does that happen. Now some of the LS1's that come in are very strong for what little they have done and that is very impressive to me.

So now I plan on having a little old LT1 that looks bone stock, not very loud and if all works out, should run high 10's NA, stock salad shooters, 93 pump gas, BFG DR's, minor weight reduction, stock looking as they come and then spray a 150 shot on that....enough to give most a problem.

But yes, the LS1 is better.

 

i like the ls1 alot, and have alot of ls1-owning friends, but i hate the attitude that in the span of a few years in the 90s, GM put together the god of all motors that are all capable of insane times and power output and will crush almost anything that is just a few years older...
