4.3L turbo- FROM JUICE TO BOOST :)
okay looking to turbo the blazer after having run juice for about a year-
Only gonna run one bank of cylinders which will make the engine seem like a 2.15 Litre engine to the turbo so im thinking about an SRT-4 turbo or a T25 turbo to spool from like 2800 to 5500redline- do you think this is feasible?
Some misc ****-
using stock manifold flipped
moving battery to the back
Front mount intercooler
Some Questions-
1.)Not much to upgrade on the fuel system on a 4.3L (cause you cant) so i am wondering if an MSD inline boost fuel pump + a vortech FMU and a COMPLETE tune will be enough for the fueling- looking to run 8 to 9 psi intercooled
2.) since im only using one bank of cylinders will either one of those turbos be suffcient? - SRT-4 - 2.4L and DSM 2gen- 2.0L- i would like a little lag so the SRT-4 sounds good 2 me- Looking for 400whp later on- so should go with a bigger turbo?
3.)i see guys using WGA on all the SRT-4's can i just use a Hallman MBC to tone the boost down?
4.) What about getting oil to the turbo- i assume since its up so high i dont need any pumps or what not correct?
5.) want mandrel bent pipes where should i order a set from? summit? jegs?
6.) 8 to 9 psi = 60 or 70whp? + im gonna spray on top another 50hp

Dont just put a turbo on one bank.Run a pipe over from the other side to join them and get a bigger turbo.Your fuel setup sounds fine as i imagine there isnt alot of choices.You cant lower the boost on a wastegate with a boost controller only raise it.You run a oil line to the turbo from a pressure source like tee the oil pressure sender etc and oil gravity feeds back down to pan so line the turbo up so it will drain.Mandrel bends you can get from a sponsor on here http://store.racing-solutions.org/

Lets not be a FLaming GAY BuTT Sex Morphidite Jew.......I really mean quit being a ******... 
It already has a crossover pipe just run it up to the turbo an for fuel system just put in a fmu an it will increase the fuel pressure an dump the amout of fuel you will need for your 6 psi boost. Y do you wann use nos when you can just turn up the boost? Just basic questions
for the newbie

-heres the deal- i have stock 19lbs injectors that are a poppet style injector there for are unupgradeable- therefore only allowing me a max of about 10psi and thats pushing it- + stock fuel pump is not that good thats why im putting the inline booster pump in- But yeah i will probably end up doing what you said- Just gotta find a turbo that is suitable-
