i at least want to get the turbo brand new...since its the main thing haha. but i got a question excuse me if its dumb, but is the turbo powered just by vacuum? or is something electrical going on?

haha nevermind, when the throttle opens..air gets sucked in spooling in the turbo then spinning the turbine...then BOV blows the **** out when the throttle closes....all this is allowed by the internal or external waste gate allowing a certain PSI to flow thru. thats determined by a boost controller.....

does that pretty much sum up turbo for dummies?

 

^^i feel like im missing something right there ^^

also, i dont think i've seen this asked before....since the boost is determined by a controller, what if you set the controller at 0psi? would the intercooler then work as a huge cold air intake? or would the motor still react as if the turbo was engaged?

 

i have another question. i know that turbo mani's have a place to bolt up the turbo, but do they also have a place to bolt up on the exhaust? or how does that work exactly?

 

You don't "need" a controller. Controllers are used to trick the wastegate... usually to keep the wastegate closed longer so you can generate more boost than the spring in the wastegate is rated for.

Reading your short turbo description has me a little confused... not sure if you got the concept right.
Inside the turbo there are 2 fans connected together by a shaft. When you spin one fan, the other turns. As your exhaust passes over one fan it begins to spin the other - it's not yoru intake creating the spinning action, but your exhaust is doing it. The more efficient manifold you have then the faster you will be able to spool a turbo.

Just about right except for the boost controller. True, you can use the controller to do this, but the WG is the main factor in determining the PSI.

 

yea i wasnt exactly sure on the turbo process, i wanted to see if i fuller understood but i dont yet. i want to understand something fully before i decide to get involved with it.

if the WG controls the amount of PSI, how can that be adjusted? i dont want to push over 10psi since im going only about 200hp.

 

So 200hp is what your goal is.

10psi is irrelevant at this point.
The psi required to make 200hp depends on the turbo you go with.
The efficiency of the turbo is what you need to be concerned with.

When you settle on an turbo you change out WG springs or diaphram actuators to regulate the psi to get within the hp range you are looking for.
Of course you can fine tune that with a controller.

 

yea thats my goal.

how about the T-25 our of 1st gen eclipse? i saw it on homemadeturbo.com and it was used with a stock d16a6. no HP results tho...

i dont want to be insanely fast, this is a DD. im going to pick up a b18a or b18b LS block sometime and SLOWLY build that thing up. Then get the head later.

also getting a spare d16a6 block "just in case".

 

A Jackson Racing Supercharger was in my head for a second.....then QUICKLY out of my head when i saw the price tag hahaha. Screw that.

 

ok well it looks like im going with a T25 1st or 2nd gen turbo, intercooler from a dodge conquest or mitsu starion (whichever i can find at pick a part), then a STD manifold.

The T25 2nd gen in internal wastegate so all ill need is a BOV, some piping and vac/oil lines and i'll be good to go!

i HOPE to have most of these things by this weekend.

 

here is a craptastic pic i just took...its kind of dark but this is the EF as of now
