Well thats a lot more than the Getrag which was only intended for engines with a max of 190 ftlbs of torque.... yet many people run twice that in some of these engine swaps.

So these friends with 600 rear wheel Hp (I guess thats about 700 hp at the flywheel right?)... what kind of engines are these in what kind of cars? How much money was spent to get them to 600 hp and run on on highways all the time in Mexico? So your car has around 400 horse power? what kind of engine is it? What kind of modifications were done to make it handle 400 hp???.... Just wondering

you can not use a normal V8 kit on any LSx motor. i got a estimate from archie and for everything you would need to put it in my manual car would cost $5,685. now that price did not include the wiring, do more money you would have to spend, and also the price of the motor. i think $25,000 might be to low after you have ordered all the estras like alt., ac, dry sump (if you kept it just like how it is in the corvette), ecm and wires. but i was just adding up one day and came up with $25,000 with out a dry sump and doing all the work my self.

Feel the need to doubt everyone?
Windsors. These cars are (for the most part) rustangs, some of them are turbocharged, some are supercharged, and some just use nitrous. Generally speaking, I don't ask my friends how much money they have in their setups. My buddy Brandon snapped his crankshaft on his old supercharged setup and is now going with a large single turbo. His new setup consists of "a Dart sportsman 331,JE pistons, eagle crank, all the good stuff inside,AFR 205 heads (out of the box),custom cam made by HPP (local performance shop),spyder intake ,160 injectors ,F.A.S.T.,PT-88 with a a/a intercooler,3.55 gears moser kit(the works great kit bought it from jdperformance.com) ,built AOD for now then to built 4R70W"
It'll be over 1200rwhp and he is still planning on driving it to a couple of meets. If you want to know how much that cost, do the math. They don't really run in Mexico , Seeing as how you're in Texas, I'd figure you'd have caught on to that. Mine? Its also a rustang, 302, stock turned crank, TRW pistons, Twisted Wedge heads, TFS stage 1 cam, GT40 intake, and a Nitrous Express wet kit. I'm on my fourth transmission and just paid $1500 for a built tranny and converter that I know will handle up to 600 rwhp. I wish I had heard about this trans. shop sooner. Also have a 8.8 rear(stock with gears), subframes, roll cage, etc.
-Since you were just wondering.
-A couple of my friends showed up to the dfwstangs fall cruise(Nov 12, 2006, @ Kennedale). There are some pics here. Winner ran a 5.72@120 with a 1.28 60ft on 1 stage. It was the ChevyII surprisingly enough, someone asked him how much $$$ he spent and he said it was personal. That's why I don't ask my friends.
If you want to take a look, here's some pics from the cruise. http://www.truestreet.net/photos/.

A stock V8 can handle 400 HP

A boosted V8? No such thing

No need to apologoze

The only people who doubt really dont know any better.

A good example is lightweight Lug Nuts and a Carbon Fiber Air Freshner...................you know who you are out there.

A 10 sec daily driver???? Thats

Most gearheads spend $$$ on a car.

Wow, I find it really ironic that your screen name matches my car . I suppose you're right on the doubting part. I'll keep wrenching .

All valid points btw, a + for you.

Just make sure nobody mentions what can be done with a Grand National and it still be a "daily driver."

What? Seriously? People honestly believe that a 4 banger boosted to 3x it's original power level (or any engine built beyond it's original intention) is going to be as reliable (in a daily driver sense) as a larger displacement engine that is designed for 100k miles without major service? Come on now... race engines are rebuilt regularly for a reason.

Just like so many other cars out there, 9 second 1/4 mile car, still streetable to boot with great idle qualilty. You don't see many Civics out there that can do that!

Seriously, if I had the $$, I'd pick up a GN, a guy drove one out to a local GTG a couple months ago and it was so clean

Having owned a GN/TR, a 9 second GN isn't $$, it's $$$$$$$ and totally undrivable in the rain.

Guess what I bet if i had unlimited money reserves I could EASILY make a -9 sec car that even idled nice!
Its all about how much money you put into it the technology is there.

And Whats nice about the LS7 is that when they figure out boosting em were going to see daily driven 1500hp corvettes
a simple cam, pistons, headers, intake, will net you over 750hp

Of course I wouldent exaclty trust that much power in a fiero it would probably tear the trans and frame to pieces.

Whoa! Hold on.... "Simple cam, pistons, etc."

Pistons, simple? Not exactly cheap, and you have to tear apart the bottom end to do it. If I remember right the big problem is the computers in the cars....I haven't read up on them in the last few months but last I heard people were just switching to a LS1 computer? c6 Zo6-supercar in its own right


TK, what made it totally undriveable in the rain? Open the wastegate, directional tires with decent tread....and some sandbags .

this might be correct, however I witnessed a mule live the other day & it was supercharged, Not 100% sure what series LSX it was, but it wasn't the Caddy's motor... and the big money is on it being bet on it being offically named the the Blue Devil.

Probably me!

It was fine on straights but just trying to turn a corner was a challenge as I would roll into the throttle a little (around n round and sideways we go....).

I loved it but didn't drive it enough to justify keeping it.

LOL. I know what you mean, I'm guessing the rear end was really light like my old vert . RIP.
