BOSS APPROVED!
Need some more advice on turbo build.
Need some more advice on turbo build. Ok well i will be receiving a bare block in about two weeks, then i am going to polish the whole block(everything will be polished heads intake valve covers etc.) i am not in a big hurry just building at my own pace and making everything perfect. Then i am going to order the pistons, rods, and crank, i am wanting to keep it at the stock bore and if i do change the displacement it will be no more than a 383, since i am wanting to turn 8000rpms. So what bottom end setup would work best for me?? somewhere around 9.0-1 compression? Id like to be able to push about 18-20psi and i want to keep a/c and p/s so i was thinking the STS kit will it put out this much boost?? Also i want to run 93 octane on the street and like 104 or higher at the track so if i get a boost controller can i run lower boost on the street and be safe with 93 then up the boost at the track with a higher octane?? I will go ahead and ask, what heads/cam should i use with a turbo? like i said im just planning ahead no big hurrys but any advice will be helpful and i havent even started so LET ME KNOW WHAT I SHOULD DO, if something sounds stupid just tell me befor i mess up.
I am also aware that i am going to have to upgrade the fuel system, so like 60# injectors, fuel pump and more than likely an inline boost a pump as well as fuel lines.
I guess thats all i have to say so go ahead and critisize im all ears thanks guys/gals

i think you should read up a whole lot more. but imo you should have a 6.0 liter iron block with no more then 370ci inches at 6,500rpms or if your really set on 800rpms i'd throw 4.8 crank in there and i think that makes it like 328ci. 8-8.5-1 compression would be better. AFR heads or better to hold the boost. you can make 650rwhp no problem with a 370ci and 10psi on pump gas and have way more fun then a 1000hp dragcar. to handle 18-20psi you are talking thousands more then to handle 12-14psi.
thas why im posting first, im not so set on 8000rpms but it sure sounds sweet ya know. what im trying to do is keep the stock bore and change it up with the crank rods and pistons, just want something to handle some boost and around 8-10 street, 12-18 strip. for some reason i just think that a smaller cubic inch will hold up better.
put your money in an IRA dude...for real you have no idea what it takes as far as talent and money goes. u think 8000 rpms sounds sweet and you THINK smaller cubic inches will hold up better. don't worry about the $4500 bucks you'll spend on a short block let alone the heads (2500+) rocker setup for 8000 rpms...over 1000 easy, the intake n throttle body a 1000. and 60lb injectors? your smoking dope man more like 72lbers (500 bucks) at least. hp tuner at the least to tune everything is $550 plus someone who knows how to use it is another $200 bucks. a fuel system for something like that is easy over another 1000. you want a turbo? $1000! you want intercooler and pipes a thousand. plus someone to do all the work to install it all. oh and then your transmission breaks $3000 right there for a good one, then your rearend breaks need a 9" $2000. save your money man. i'm not picking on you just giving you the facts, these guys on here don't play and even still most of them don't know what they are getting into
First off I would establish some rwhp goals, not boost goals. Personally I would keep the stock bore and stroke if you plan on going with a turbo. As for the STS kit, I dislike everything about the kit. Just not my style.
Budget at least $15,000 for a forged short block and a quality turbo kit along with a decent fuel system and upgraded driveline.
Good luck,

Well its a project, and i was figuring around $10000 money wise. As far as installation im doing it all myself, the only thing i didnt really figure in was the transmission, but i figured the rear end would have to be replaced sooner or later.
heres what i had
Crankshaft(Callies)- 1600
Rods (Callies Compstars) 600
Diamond forged pistons- 650
Total seal rings- 200
Oil Pump 180
Cam 232/240@.050 .595/.608 lift 115 lope seperation 400
lifters 200
Fuel pump (Wallpro) 160
Fuel injectors 500
Radiator 300
Thermostat 60
Heads(possibly reuse mine) 2000
STS Turbo 4200
Total 10,650
That was my original setup which was like a 383, i just remembered i need an intake also unless the ls6 will work.

What kind of hp numbers do you want? LS6 intake is good up to 750-800rwhp of boosted power. Stock throttle body is fine for that too.
Your fuel pump will need to be a 255lph MIN, but most likley you'll need 2 and lines.
Forget reving to 8K. You'll make a stupid amount of power by 6500 anyways.
Also forget these "haters" talking about hondatech. At least you sacked up and asked the questions. That's the only way to learn. When you make crazy power, they'll look more foolish.

. nah its all good, i expected the comments. and thats the only way im going to find out what i need, anyways the project is still a go so ill see what happens.
As far as hp id like to see 600-650 maybe more.

Hey man, I went through the same as you when i first signed up here a while ago. i wanted a procharger or turbo set-up and once reading a TON of stuff on this site its just such an expensive route that I decided id start off slow then maybe down the road go turbo or s/c. Id suggest, since you already have money into a heads/cam setup that you simply forge your bottom end and either stay 346 or go 383 if you really want and spend the rest of the money on a transmission, 9 inch rear, fuel system, and a direct port nitrous setup (say spray a 150-200 shot). This would get you to around 600+ rwhp and would be a beast and youd have the rest of the car setup to handle the power. Also, it would be a lot more fun on the street as you would at least have some chance of getting traction with the heads/cam/nitrous setup whereas with the turboed 383 once that turbo spooled and you hit boost you would boil your tires. Not trying to talk you out of a turbo, just there is soooo much more that goes into it, including massive amounts of suspension work to get that kind of power to the ground. Good luck though with the buil and let us know what you end up choosing!
