Alright folks, what am i looking at?

Im in the process of building an engine for my GTO. So far i got an LQ4 engine block. Next step is to order a stoker kit.
So what will it take to achieve a 9sec DD GTO? Yes, i said DD.
Anyone here been there with a gto? And yeah, no spray.

I know this is going to be a long project, but hey gotta start somewhere. Fire away!

Ps. If you are goin to reply, plz make sure your post is beneficial. Dont f up this thread with lame remarks, sarcasms and smart a** replies. Thank you.

First a "lame remark" you wont like. Just from this post I have to think YOU are close to a decade off from being knowledgeable enough to put together and maintain something like that. Kids come around with wild plans and don't want to be told they are unreasonable.

That said, you don't want nitrous, but only mentioned stroker and didn't comment on boost. Feelings on boost?
If you think NA is the ticket and that displacement is the key factor then give up right now.

Do a search on member "ptero" and do some reading about his build on his GTO. He has run in the upper 9.90s with a NA 454 stroker motor with all the goodies. He has managed to get the #s , but I promise you it was not an easy or cheap road to go down. To be a daily driver is asking a whole lot, guess it just depends on what your definition of daily driver is.

Its not gonna be a wallet friendly build by any stretch of the imagination.

All i said was no spray. I did not say no boost! My question was clear! What would it take to achieve a 9 sec gto w/o spray.
I dont see where in that question there is anything about wanting it to be n/a.
I mentioned stroker kit because that is the next thing on my build. I did not say i am looking to achieve 9 sec with only a stroker kit.
Congrats! Your post fits everything on my p.s. And its the first post too.

what tranny do you have ?if a A4 get a high rpm stall converter .consider a Texas Speed stroker rotating assembly.with a big enough bore get some ls3 heads .a fast intake mite be better then a stock GM ls3 intake.get a custom cam after you have all the main parts.you will need the right gears also.

maybe you could change the title to "I have a question but only give me answers I want to hear".

Why start with an LQ4 block?

BEFORE you consider the engine you need to decide on NA or boost.

I would guess you'd need 800rwhp with a D1 and meth.

And a built trans and rear obvi.

How practical is boost on a 408? Been told dont need to go big on cubes if boosting and that it is even counterproductive. How true is that? If at all.
My logic is if i go big bores than i dont have to get a big blower to achieve impressive #s. On the other hand, if i go with like the stock cubes than i would have to spend major $$ on the blower to achieve the same #s. How flawed is my logic?

Boost on a 408 is common, they are proven..

I would study up in the FI section, save your money...

Get ready to **** your gf/wife and family off for how much your going to spend on this project lol..

But if you have to ask what it will take to get your car into the 9's, and you want to skip 12's, 10's, etc.. Then you need to do a lot of studying...

It's a very involved build to get a car to go that fast and not break or blow up first time out..

You will spend more than even you believe.

Because you will try to buy the right thing the first time. You'll change your mind, and you'll buy something else absurdly expensive. Blahh.

im doing the same build, just with a lq9 block, 408 , and im not expecting 9's at the start lol, but some where mid to high 10's, im definitely boosting it, texas speed has nice rotating assemblies, im going with zo6 cam, ls3 heads, and either a fast intake or the factory gm ls3 not sure yet.

Freefallin

Weird! I just looked up this dude pedro that floman was talking about...he is in the 9s with basically just an ls2 base 454 and ls3 heads, fast intake, some exhaust work and i few goodies here and there. No boost no spray! Yet you guys are making it sound like its going to be an extremely difficulty thing to accomplish. Im confused :/

At a minimum you will need 750 hp to the wheels. No way is that happening with a N/A 408.

I know a guy here in Kansas that has a 454 LSX block GTO who runs a low 10's. But, it's not exactly a car you can drive everyday.

Its not going to be that difficult. You just have to get all your stuff planned out and buy the right stuff the 1st time. A 408 will be a good starting point. I would also go with the holley efi hi ram ls3/l92 intake and a pair of lsa heads. Because for boost your gonna need to be able to move alot of air. Are you keeping the irs or going sra? Running single turbo or twins? What trans are you gonna run? (4l60e 4l80e th400 t56 etc?) but as you already see either way people are gonna say what they want so just build your car your way and shoot for your goal.

A 454 LSX build isn't cheap...

Freefallin

ill keep irs and i havent decided on the boost yet, procharger or turbo? Still researching. Any suggestions?

Money+More Money+ Crying= 9 sec time slips. Basically gonna need a MINIMUM 750-800hp, built motor, trans, rear, and lots of suspension work. Even with all that it still may not give you a 9 sec slip.

What one or two guys manage to do has NOTHING to do with what a clearly inexperienced newb can accomplish.

That is why I made the the comment
