Turbo Charger Question!!!

[HottRodZ28]

Im thinking about buying a turbo, now i did have a powerdyne SC and i loved it but it was too much of a hassel when it came to motor maintance, and i dont have the time anymore due to the fact im in the Army, So i was looking into the STSturbo and i was wondering what should i do with my stock heads??(replace the internals to better ones??) , and what type of cam should i put in it??, i have 75K on the motor so i dont really want to rebuild the motor unless it blows , how much boost could i run on the LT1 safely but i want the car to move, Now through STSturbo i can run 7lbs of boost with their setup, could i go as far as 9lbs but with their methonal kit and of course PCM tunning ???....thanks

My opinion is that a turbo system would quickly turn your stock internal parts into itty bitty pieces. It's one thing to bolt on heads, cam etc.... but the stock pistons don't tolerate alot of boost even with a fresh engine. You've got some miles on yours. Not that it couldn't withstand some boost, but for the dough you spend, it would be nicer to be able to run some decent boost and have the internals live. My advice is that if want a turbo, which I love..... You better put in good pistons, crank and rods. Then it's wwwwweeeeee! That way it will do it repeatedly.

Or go with this...



Got that pic from GNTType.org. I love that motor

how much would boost would be acceptable , because i did run 6lbs (5.3~lbs) with the SC, because i would limit the boost if necessary until things GO with the motor, cause i do need to wait a little longer if i choose to do internal motor (pistons, crank, ect), considering if i do that ill be spending some real money along with another tranny to handle this power, i just want to come home to a car with some boost and power considering the army isnt all fun and games, unless im playing with my M4...
Thanks

the stock pistons can handle at least 4-5 psi, there are some that managed to run a pound or two more. That is... until the ring lands crush. These pistons are built for a normally aspirated use. If you want to add the turbo first, you can. Believe me when I say you want to keep it at 5 psi or less. You have to use good fuel too. Whether Mars aligned itself with Venus or some magic charm spell was cast, turbos will at one time or another manage to overboost. Unless it's computer controlled, it WILL happen and that's where the damage is done. Keep it conservative until you upgrade the internals. There is also something to be mentioned with bearing clearances. What is used for higher rpm and naturally aspirated should not be used in a lower rpm boosted application. Make sure your builder (or you) knows what is correct for the intended useage. Now once you get everything in order, it can make some wicked power. Better have a good rearend and tranny. As a comparison, my Buick 3.8 V6 handles 24 psi. Haven't had it on a dyno yet, other similar combos are in the 650 lb torque range. It pulls like a bear. The first full pass got me a 10.91 and was summarily tossed from the track due to not having enough safety equipment. The difference is that motor is built to take that kind of boost. Do that with a stock GN engine and it's literally blown apart much like what would happen to an stock LT-1 (don't ask me how I know) , just with less boost. The bearing clearances are different, the rings are different, rotating assembly is all forged, 0-ringed deck/heads, block girdle, etc.

There are guys that will push a stock motor with more boost, but in the end it all comes apart for a rebuild in a relatively short time. Usaully at the wrong time too. Hope this helps.

Thanks man!!!.....SAme thing was said by my tech. and im goingto go with the rebuild first, might have it at 8.7:1 compression and ill have all the goodies to just handle BOOST nothing else, in specific for the TURBO setup (stsTurbo) I like the rear mounted idea plus its a new idea and ounce i finish my project ill have pics, videos, dyno charts, 1/4, to prove that its a good system. All matching parts like cam, heads, ect ect ect ect ect will follow the engine ....... Now the only thing im worried about is the damn tranny, i just had the P.O.S rebuilt and now i dont know if it will handle the 10-15lbs of boost im going to stuff in the engine Oh well ill blow it up (ill have fun!! )and ill put a ________???? please help fill in the blank! The rear i dont know i have an Auburn rear with new bearing and superior axles, girdles, so i guess it should hold with the stock 10bolt cast ....i guess ill see what happens....Overall thank Joe you helped out a lot and this time ill give my camaro the attention it needs

Also look into these guys for a kit. I agree with all the posts about build for boost. Thats why for now I'm going on the the bottle.!!!!!

Very nice. Just wish they had some pics of the kit installed on an F-body. Looks good on the Impalas. But, I think I'll stick with my current turbo setup myself...

Your rear end has a decent chance of holding up unless you use DR's then its just a question of when will it go. And I'm not very experienced with A4's but if you would want a manual this may be a good time to get one or their are kits to have your A4 really beefed up or go with something like a turbo 350 would hold up well.

I give the sts guys credit for their kit. However, the price seems too steep for what you get in the kit. My plan is to go with either the PTK Front mount turbo kit, or a LE2 H/C package. Check out the link, prices seem excellent.

Oh one more thing what should i put as a stabilizer for the oils and fuel in the camaro, i offically took the camaro off the road for construction and i took so parts off like alternator , fan, radiator , battery, alternator bracket (broke it opps over tightened the damn bolt!! ) but im shipping out for about 6months but ill leave any exposed parts covered and taped to minimize any futher rust, oh what about my damn brakes, rotors, calipers, what should i do about them??...i never let my car sit for more than 4weeks without starting or driving. any suggestions?

[HottRodZ28]

WOW thanks again, jezz you guys really look after one another with F-Bodys, living in NY youre basically on your own cause there're A$$h0le$ around here that only care about their own ride and just want to smoke you. Plus the number of Rice rats are as high as the count of a 500lbs bag at the china buffet. Its really pathetic , but do you know any other tubo kits front or rear mounted?
Thanks
