Now whether I decide to stick with the turbo route by the time I have the money I have no idea but obviously low boost is required untill you rebuild the bottom end. I was thinking about doing the motor in stages for financial reasons, since I may or may not have money to do the topend at the same time, so I figured keep the top end stock and build a stroker, most likely 383, now I assume the only downside to a 383 turbo with a stock topend is no higher rpm power probably above 4500rpm until I decide to put money into the topend, which is perfectly fine with me. BTW I would be building the stroker after the turbo was on. Another question is how will a stock LT1 cam work with a turbo, now that may be a vague question depending on my turbo and the setup i use but if there is anything to say about it please do. Seems like my only other expenses would be a clutch, dyno tuning, and I cant think of anything else at the moment.... Is this worth attempting if I cant do it all at once, I have heard of some good numbers coming from stock heads so I figureed ide ask..

 

You will definately need the new clutch. I burned the stocker the first ride after the turbo was in. and that was on the stock motor. I ran the stock motor for over a year and a half. I made the Hp TQ in the sig for the stock motor. After it was rebuild time I upgraded the turbo, the intercooler(s), and did heads/cam and I picked up 170 Hp and 136 ft/lbs of torque. The stock cam will work, but is not optimal. The valve springs on the stock heads are also very week, I'd replace them if keeping the stock heads. If your keeping the top end at least get a new cam, upgrading heads later will not be a problem, though you may need the cam to be upgraded then as well.

What turbo Kit are you going with (please say PTK )

Lt4fd - I think that will be a fine route and plan you are taking. I know on the higher HP turbo motors (2000HP) that turbos respond to stroke more so than bore keeping the same ci, so the 383 is a good idea.

Im positive you won't be limited to 4500RPM by the stock heads and cam by adding a turbo. Im sure it will make good power to 5500+. Give me the stock cam specs and I'll give you my opinion on it. Basically if there isn't much overlap it will work fine. I prefer having more intake duration than exhaust for a turbo cam and having 0 or negative overlap.

Also what kind of power are you wanting to make with this? What turbo?

 

Sounds like you have most of the bases covered here.

Stock head issue..
I don't see it as a problem cause boost will cram the air in just make sure you have a decent intercooler and it can get alot of air across it. (I am not fond of the intercooler in front of the rad at all (ie turbo tech, QTP, CAS etc..)

I would seriously look at the Pro turbo kit rather than Turbo technolody with what you are building I just don't see the system supporting the hp levels you will be hitting.

My 383 single Turbo Tech turbo setup was making stupid tq and ok hp. Only thing I look back on and regret is that the system just needs to be modified so much to work fantastic. Things are just too small.

I have seen people use the stock cam but If you have the engine all apart it isn't going to be that much more to put a diff cam in or even possibly grab a used one. Seems more and more people are running turbos these days so the parts are coming to the market more.

What are your down the road power goals?
What is your budget?
Daily driver?
I would seriously sit down with a turbo company (innovative or Limit engineering and discuss turbos with them. See what they recomend for your car.) Some people think there is only 2 turbos (60-1 and t-76) which is far from the case and to get your turbo working in the sweet spot will make for alot more fun.

Enjoy the research it is alot of fun to do.

I would suggest that you run a aftermarket DFI system to make life alot easier on you.

 

Wow I hardly remember asking all that I was soo tired, surprising that it was actuallya valid coherent question.....anyways... Yes I was thinking about the PTK system since you get the option of choosing the turbo you want. I would think a dfi stand alone system would be great but im not sure at what point it would be necessary and a lot of $$$ dunno what ill be able to afford, maybe add that once I dive into the motor work and keep the stock pcm while running low boost on the stock motor. Yes this will be a daily driver and my budget is unknown but I do know it will take a good while to save enough unless I get a second job which im looking into. As far as power levels go I really dont know, how ever much I can get away with while staying reliable enough to drive daily to and from work and joy ride of course, and not get tooo hideous gas milage, and what ever the pocket book will allow of course..... sooo vague

 

As far as power level goes the more cash you got the higher u can turn up the boost. You want to have some type of power goal. Because you are going to build up the bottom end around that.

 

Well I figure ATLEAST 500rwhp eventually, have to do more research to see what it would take to have a daily driven 600+rwhp car from there I could decide if I could ever afford all of that. I mean I dont want to spend money on a forged crank if its not necessary same with H beam rods, but Ill just have to do some more searching. Thanks for the replies
