L67 or v8?

[Jamiejamie]

so at the mom I've got just a ecotec 6 with a few mods. I know it would be alot easier to just buy an 8 instead Of an l67 change over but it seems like so much fun to do the conversion. If I were to do the conversion and work it a bit it would cost me more than to get the 8 but can anyone give me an estimate on power if I did the conversion but upgrade the l67 with cam and rockers, manifold insulator, intercooler, bigger pulley upgrade, supercharged heads, double row timing chain, hydraulic roller lifters, air to air intercooler plate and a tune and top it off with a 3.9:1 LSD, shift kit and bigger stallie. Know it would be heaps easier and cheaper for the 8 but think this would be a ball. Can't decide...love to hear from people who have gone down this road.

Going down the cam, intercooler, boost, exhaust path seems to get around 220rwkW and a shitload of torque. Have a look on l67torque.com and see what power those guys are making with similar mods

worked L67 will still get owned by a stock LS1

^^Brutal honesty^^

Take that advice an chersih it.

[GEN3RATD]

obviously its much easier to swap in an L67 and it wont be a slug, just in no way shape or form get your hopes up that you will be able to keep up with stock LS1's, and probably regret your desicion down the track when all your mates buy LS1's.

[Jamiejamie]

Not denying that, I know that, it would still be cheaper to buy an LS1 and do some work to it than to do everything I've mentioned above. I would love an 8 but would also love to build up an L67 for the fun of it regardless of power differences. Will more than likely go with an LS1 though.

[rbk_212]

its true if your looking for speed and your gonna engine swap you want an LS1.

But if your more just doing it for the challenge and experience of doing the swap and modding it all that jazz you were talking about then go the L67 if you think youll enjoy it more

I must state for the record though V8 sound, torque, tune ability and credibility all day long over a barge old iron six

[Jamiejamie]

Agreed. I wouldn't swap out my engine for an LS1...way cheaper to just buy a whole new car.

[GEN3RATD]

if it were me, id just sell your car and buy an LS1, then once youd have that, sell that and buy a turbo 6.

Couple of small mods on the l67 will have you eating the 5.0l for breakfast.

who said anything about a 5l? totally irrelevant...

Couple of small mods to the RB26DETT and you will be eating 1JZ's for breakfast

about as relevant

definately right,

i just assumed you were one of those people thats like mega attached to their car and wont just sell the thing to buy something better.
Depends on what your looking for from the end result really

[VR028]

Refreshing to see some people with common sense on this forum.
As above, You will never look back and regret buying another car with an ls1 already in it. Huge time and money will be saved

i know what you mean, the amount of people that think its feasible to do a LS1-T56 swap for pocket money astounds me

Jamiejamie, this forum is membered by what would appear mostly 8 cylinder fans so im not surprised at the sided responses you've received thus far, and these types of threads always end the same. If this is your wish to build a worked L67, don't be put off by those that doubt the potential. Comments such as "a worked L67 being owned by a stock LS1" is not quite the case at all. I often wonder whether those that downgrade a worked L67 have actually ever driven one before passing judgement??? A quick L67 is certainly not a cheap path to take if done right and built to last, but is definitely loads of fun.
Don't get me wrong, I love a nice V8 as much as the next guy, I just find it amusing the path these threads always take.
My 2c anyway...
Cheers

there you go champ. if you arent one eyed a ford XR6T will eat most V8's and L67s assuming you get the right mods.

The "a worked L67 being owned by a stock LS1" comment surprised me a bit too. After driving my mates stock auto VX SS I can say my little l67 with mild mods is easily as quick to 80 km/h, and feels far stronger low down in the rev range.

No doubt if he had an intake, exhaust and tune the LS1 would eat my l67, but in stock form its another story.

have alook on you tube at l67's dragging v8's...

ok then, theres a very small majority of owners of LS1 owner who actually keep them stock. exhaust/cam/tune against an worked L67, i know what id put my money on.

[wana s' charge stock vt]

what time does a ls1 with cam,exhaust, tune, run down the quarter mile???? (just roughly) 10,11,12,13sec????

[GEN3RATD]

too many variables, auto, with a big cam and stallie to suit, OTR and maybe some 3.9's will pull low 12s on street tyres high 11's on slicks all day long

[ucwepn]

Both engines were choked at the factory for durability and for later model power upgrades, if you spent similar amount on each the v8 would always win but it comes down to personal preference, I was looking at some scv6's when car shopping but i went with an 8, happy with my choice as long as the thing hangs together lol. scv6 probably the more durable unit. All comes down to what you want choose carefully and do allot of research.

gee's dude
so a ls1 with auto, big cam, stallie,otr,3.9's,exhaust and tune only does low 12's?
wtf does a 'stock ls1' do then ????? lol and how slow do you think a worked l67 is??? high 15's??
