Ive seen these things poking around the net and i was wondering if anyone has driven one? Or know much about them they claim there is no lag i find it an interesting set up.

I can't understand how there would be no lag. The exhaust has to travel from the engine to the back of the car, spool up the turbo's, and then the boost has to travel all the way back to the front. With all the plumbing I would expect not only massive lag, but loss of boost pressure, poor turbo performance due to lost heat, early turbo death because of how far coolant and oil has to move...I just can't understand why anyone would run a system like that.

Yeah it kinda goes against all turbo tradition the thing is most of the people who have actually driven one claim to like them. They also have a bunch of kits so they much be selling some....either its a solid product or they are good at peddling snake oil.

I bet running oil lines for that would be a blast...

Consider me a skeptic then. If I get a chance to drive one and see for myself that it's a great system, then I'll eat my words, but for now I think it's junk.

I'm with you but forever an optimist

Yeh, that directly defies the common methods used to cut lag. Lots of air in those pipes to compress!

I found this article in super Chevy. At least its little info from an outside source.

Remote turbos work! When sized right.
Generally a smaller a/r than front mounted becuz you're not running big boost.
It depends on what you want.
Lower boost (good- no race gas and bad- not as much HP) and no intercooler and the associated plumbing.
The oil lines really aren't much of an issue as you use an auxiliary oil pump.
This setup makes the most sense to me when dealing w/ an SVX.

i don't doubt that these systems improve performance... i just personally don't understand why you would go through the same if not more effort than to just build a regular (better) turbo system

Better would be subjective. More potential HP w/ front mount.
You wouldn't have to necessarily build a lo comp motor w/ remote, becuz boost is generally <10psi. Which makes tuning easier. Weight distribution would be another reason. As well as no custom exhaust manifolds. It's WAY easier to install one of these than a front mount, even if there were a kit turbo system like for 'stangs and camaros.
Also you can return to stock for smog inspections. Cuz other than the oil pump and i/c piping, you can yank the turbo in no time and plug stock air cleaner on.
I've been have this same discussion w/ myself for the past yr as I'm working on a turbo system for my 68 Pickup.

If I was going to be running low boost on a turbo, like 7 or 8 lbs, I would just go for some NA performance mods.

Standard turbo:
-custom up-pipe
-custom down pipe
-custom bracket for turbo "just in case"
-oil filter conversion flange
-lines for the above
-a small amount of custom air piping

vs:
-custom exhaust system
-custom annoying air filter setup that requires constant checking and fear of driving in rain
-custom mandatory bracket for turbo
-oil filter conversion flange
-extremely long custom lines for the above
-LOTS of custom air piping back to front with no where to run it

...watch out for them speed bumps.. driveways... well lets, put it this way, my fist can still touch the ground while touching my car

add a pipe under that!

do what you want man, i'm just saying.
also the bulk of any added weight with normal turbo would still be behind the front wheels.. you'll need an intercooler for either arangment to improve, MORE so with the remote system due to the fact that you're essentially baking the air on the return trip

I guess it all depends on what your level of confidence is for customization... but really if you can do one there isn't much reason you can't do the other since they will both require the same skills to customize for the svx

Schralper · #15 03-09-2008, 02:07 PM

Yep to each his own.
There are WAY better options than an SVX to turbo, if HP is your goal.
If a fast SVX is your goal, go w/ a built N20 motor and then a manual tranny.

But the fact is that there is no custom exhaust w/ remote. You could use your stock piping. The custom turbo bracket is an exhaust hanger like OEM.
Oil filter conversion? You just need an oil feed and return line. Generally stock drain hole for feed and then a fitting part way up pan for return. No intercooler unless goin full race. The cold side piping is the i/c. The tuffest coldside feed would be up to the MAF/TB's. But the whole lack of tuning options, unless running a standalone ecu, would deter me on ANY turbo for a SVX.
