For those interested

I will be modifying my Tahoe. Going Turbo on the stock 350 before I do the complete pro-street build. Probably stock cast internals while I'm broke. If I can get some speed-pro forged pistons to fit then I will go with them, since they are only $30/pop with wrist pins included. All depends on how much I have to save for tuition and how much this job at the ford dealership is paying out. Goal is no more than 400 on the ground on a single. Considering Holset hx35w or T6x. I'm only sizing right now and planning, but if yall want to see the pics of plans I have thus far, let me know and I will post them up.

if you had the 427 (and 60K) this would be badass...http://www.lingenfelter.com/pack_suv_427h2.htm

Sorry if it seems I am having a convo with myself, this was pasted from another site I visit.

I started this over at turbomustangs.com, so some of it is a copy/paste. I'll update it when I have something worth saying.
JUST starting, but I figured I would let yall see what I was doing. Also, from what i have seen, not many projects like this has been done before, so I figured I would give those few interested a place to look. This is an extreme budget set-up and will take some time, so yall bear with me.

*1998 Chevy Tahoe with 5.7L Vortec 5700

*Factory stock besides exhaust, rims/wheels and a stereo.

Just in the planning (mental masturbating as some say) stage right now. I was considering a T04E-60 but decided it would be too small as a single. This is what the foam is modeled after though. As you can see, even with a larger turbo, size will probably not be an issue. Especially once I move the battery to the rear.

6" X 7" X 8"

^ With Air box and ducting pulled up.

^Ideal position.

^With some gentle messaging (sp?) of the lines in the compartment, I think I will be able to come up with at least 4-5^3ft of working space.

Please excuse my rudamentary design criteria, I lack the petty cash($10,000) to pick up a copy of AutoDesk Inventor or something of the like for designing. I'll make some official designs when I return to school after spring break. The exhuast is already routed to the pas side, so I think I will do as I saw somweone esle do. Keep the drivers side manifold the way it is and just cut off the exhaust and fab up a pipe that will connect to the custom ps manifold. I will be doing some research into airflow charicteristics, as I do not want to choke the turbo with a shitty exhaust mani design.

*Img rights of the creator. Image was linked off of the turbo bible.

Just looking over it and wanted to say sorry for the poor image quality. Twas a cold, late night and I was all alone. Updates along with questions and plans will come soon. Any and all comments are very welcome.

Thanks for looking!

Randy

And yes, that TT427 would be awesome, but I think I could do just as good with 1/10 the money. May not have all the goodies, but the power would be there.

Save ya moeny and just build it once, and a turbo doesnt sound like all that great of an idea on a stock motor,pending on boost I guess,but the cast crank anit gonna last long if u are bilding a nice powerful motor

the budget turbo build usually includes some corvette headers turned upside down...keeps you from having to buy/fab some tubular manifolds...

It's easy for some to say build it once. //content.invisioncic.com/y282845/emoticons/crap.gif.7f4dd41e3e9b23fbd170a1ee6f65cecc.gif

Boost would be no more than 11PSI with forged pistons. If I run the stockers then boost will be lower, around 9 until I can afford to get the machine work done or buy appropriately sized pistons. Even if I were to double the power though, from what I have been researching on crank tolerances, cylinder pressure and crank tourque, I think it would still handle it for a while. With only 400, I think it will be fine until I get the money to replace it or the money for my World/BigM.

Also, I don't know if you read, but I won't be racing much. The mtoor won't be built for it, don't have the money to drive there either

If I go twins, then I will look into that. If I stick with a single, then I will go ahead with my current plan. As for fabrication, I actually want to fabricate the parts. Some may hate fab but I love it. Maybe I'm just different.//content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

you can just run a cross over pipe from the drivers side mainfold to the passenger...id get some pics, but im lazy.

Got ya covered

Tis my plan, but it will require fab to create the PS/ final collector. So either way, I have to fab something. Which is cool for me //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

adding any kid of boost to basically stock internals (yea I know, forged pistons) will only cause more havoc later... //content.invisioncic.com/y282845/emoticons/eek.gif.771b7a90cf45cabdc554ff1121c21c4a.gif

Motor won't be used later , and I'm not gonna be driving it in a way that will cause problems, until it is built in order to handle it.

 

[RandyJ 10+ year member]

And also, with support from seevral old geezers who were roots blown on basically stock motors , and a large mustang crowd that is turbod on stock motors, I feel confident that the motor will hold up with the build/useage I plan for.
