383 stroker turbo questions

I am new here and I am wanting to try to put a turbo on my 383 stroker. I don't really know too much about turbo's, and everybody I know that races run blowers and I want to be a little different from them. What I was wanting to know is first off will my engine be capable of having a turbo with the current parts I have? My motor is a .030 350 with a 383 crank .010main. I have Pro TopLine Lightning 23deg aluminum 220 heads with a 72cc. Scorpion roller rockers with .0100 oversized harden pushrods. Comp Cam 274 int./286 exh. with 0.487 int./0.490 exh. lift. Edelbrock Victor Jr. intake (1 inch taller) with a holley 800cfm double pumper. Holley blue electric fuel pump. Hedman Husler headers. A hamburger 7quart oil pan, and a pete jackson noisy gear drive. I think thats all. In case it wasn't obvious I am only 21 and I am just getting to where I can afford to do stuff and I wanna learn more. I am open to any suggestions. I am hoping to get about 375hp out of what I have now without a turbo, but my main question is can I have one with what I have now? Anybody got any suggestions on about how much hp I may have now? Thank you any help is greatly appreciated. sorry if I forgot anything. I have never learned anything from someone that always agreed with me.

I see a few things that need to change for a turbo. The cam is out the door. It would be fine, but you need a cam with 112-114 lsa and I dont think the comp has that. I am not sure what your CR is, but as long as you are not over about 9.5:1 it should be fine. Higher than that and you would have to run race gas. The carb would have to be modified a little and you would need a fuel pump capable of 6psi plus however much boost you plan to run. Usually it takes an EFI pump to get this. You then need a boost referenced FPR like a Mallory 4309 or similiar. Then you just start piping.

I have been through this so I can answer most of your questions.

do you have a forged bottom end?
pistons ,crank, rods?
if not I would go with the smallest boost possible.
I got a 383 with a F1 procharger in my 69 camaro.
I didnt have forged lower end and paid the price of a new block.
(cast crank blew apart)
So after 4800.00 I got a new lower end with all forged parts and car is a rocket now.

Sorry it was late lastnight and I forgot about the bottom end. I believe I have a forged crank with eagle rods and keith black flat top pistons. I also forgot to add that I have a set of March serpetine conversion kit pulleys on the way and should be here sometime this week. Thanx for the help, everybody else I have asked at other sites tried to degrade me and make me feel stupid for even askin a question. Once again thanx

I have to hijack here for second. hey DAWG I'm curious about the F1 setup your running. Any track times? How much boost? intercooled or non? Approx how much HP you putting down? I'm in the works of an F1R on my 406 just got the engine tore down for a piston change amoungst other things.

Work_n_progress It would probably be alot easier for you to bolt on a supercharger kit if you want boost. I would have gone turbo but it seemed like a bigger pain in the *** than just bolting on a procharger kit with directions included. Not to mention turbo seemed more expensive & more fab work was involved than just bolting on a procharger kit. But if you want to be different go with it.

I took the easier route because I didnt want to run into many complications and can get a good amount of power out of a blower.

planning on doing the same...

hey folks, im new at this so bare with me for a sec. lol

i have a 79 z28 camaro w/ 383 stroker as well that i bought already pritty hooked up as far as the motor, but the problem is i have no clue as to wat parts are in it besides a cam, pistons, roller rockers, full exaust, rear end, and gears...

the guy showed me dyno print outs that he pulled in the car right after he dropped the motor in and it was pushin a lil over 425hp to the wheels. but i want more from it so i wanted to go twin turbo on it, but im not sure on what all i would need for the setup.

wats tha minimum size turbo needed to actually "feel" a difforence?
is a intercooler needed?
where would i go to get the piping done?
besides turbos, intercooler, wastgates, and blowoff vaulves. what else is needed to have a complete setup?
wat is belived to be better? rear setup where the turbos are closer to the fire wall or front setup where there towards the front bumper?

i was a tuner freak as well b 4 but i never got as far as a turbo upgrade but ive driven friends cars that were turboed and loved the whole experiance of it.

i hosistly just want a great street car. strip times arent too important to racers here in las vegas. ive already beat a 09 challenger twice in it but he still kept up with me by about a half a car length, i wanna murder em next time 1 steps to me at a light thoe! lol thats why im doing this upgrade.

thanx for the help, and sorry for the dumb questions but im still a newby to turbos and muscle cars all together,lol.

Rather than hijack this thread, start another with your questions.
