IIRC the car came with an LS7 but its not a z06 car
I would just start with an LQx block or even a 5.3 block for a turbo setup
5.3s have INSANE wall thickness

It's tacky. Roush mustangs are a joke.



So the previous owner put an ls7 in it? I wouldn't put an iron block in a vette. That is 110lbs they don't need on the front end. For another $800 you can build an aluminum ls2 or ls3. They are plenty strong to well over 1000hp. The 5.3 is a great bang for your buck using stock parts. It's no place to start for a max effort type of build. I have a 390ci LQ9 in my formula.

I saw him at the car show after he sold his C5 and he had that c6.
I noticed it was not a real z06 and asked him and he said yea your right but it has an LS7 block
Not sure why the car ended up with an LS7 block.

Dont they have stock block 5.3s making 900+whp?
By stock block I mean stock everything besides headgaskets and bolts
Not sure how much power stock LS1s are making but I dont think its in the 900+ range

More specs on the LQ? Heads? Auto car?

how are roush stangs trashy?

i understand stage 1 and 2 is pretty much a waste, but stage 3 roush mustangs arent too bad?

545 hp, not the most, but not bad for a 50ishk car.

Because it can be done without all the bullshit roush signs all over the car

You can just buy a supercharger and have more than 545hp
starting with a 420~hp engine and gaining 125hp from adding boost is pretty shit. Thats what just over 25% gains?
I know they are designed to last ect but other kits work better and cost less

true, you also pay for the name and shit. i agree with that its more so of a waste, but some people like the idea of having a "special" mustang.

It's weird someone would spend 15 grand on an ls7 to put in a c6.

They do, but it isn't something you would want to rely on day in and day out. At 650-700whp they are much more reliable. The piston ring land area is the weak spot on all of the cast piston lsx engines. To make that power on stock pistons you have to open up the ring gap. The factory gap is not set for the heat of boost. Once you do that you will be good until the rods bend or you detonate. It only takes 1 time to fuck it up. E-85 or race gas is the secret. Lots of people get greedy on pump gas with high iat's. It's been proven that the block and crank in any lsx is good for over 1000hp. The factory cast pistons and cracked cap rods are not.

Aiming for 4 digits at the wheel on kill with a yet undetermined t6 flange turbo in the 88-91mm range. E85, huge injectors, all that jazz. It has a built t56 in it now converting to 4L80E. Needs a rear end. Probably going with a Midwest chassis fabricated 9" with a spool and their suspension. Street car. The engine is together and in the car but it isn in storage. I haven't had time or the space to work on it in 2 years. I've been dealing with things called priorities or something I forget. It will be a while before I get to finish it but I'm not worried. I have no plans to sell the car. I drove it to high school with h/c/I and its payed for.

Yea not sure why roush has "stages" kinda stupid
Here is a company that is way better than roush could ever be

There is the problem. The body kit is hideous to me as well. it's the opposite of clean. It's really not special when it just the name. Anyone could have gone in and bought one.




They do some good stuff on the gm side too.

Nice
4l80e only way to go on a turbo setup
I have ran E85 in a number of cars great stuff for the price
That one guy with the insane fast fairmont with a 5.3 swears by not regaping the rings on his JY 5.3s but I think he is insane
That much heat you need the extra space for the rings to expand
We ran wisecos in a supra build and gaped the rings to blown/nitro spec(according to the card) and it had some of the highest compression tests seen on a supra(was a high compression e85 build but still)
It had so little blow by there was no need for a catch can. Had open valve cover even at 23 psi it was barely blowing anything out of the vents at all on the dyno
Not sure why people are scared of running big ring gaps

My fbody has gone mid 10s on stock rear end 3rd gen that weighs almost nothing. Also its on footbrake T-brake would kill it. Yea with a turbo LSx you going to need a new rearend in a 4th gen.
People have ran into the 10s on the 10 bolt right in a 4th gen?
