Sequential Turbo or Turbo+Supercharger... are they possible?

Hi guys. FYI- i searched for a good 25 minutes and only found a few things on the matter. I'm wondering what would be the setup for us US lancer owners. I was torn between deciding on a sequential turbo system (not really a twin per say) with one large and one small turbo, thus getting rid of lag and having spool through a wide selection of RPM's...or... going with a massive turbo, a Garrett or the likes combined with a supercharger to spool it up at lower RPM's to provide power all through a variety of RPM's too. I'm not realy sure if either would fit in say... an ES, or which would be more cost effective. I do know that it would be better than having say just a twin turbo system in an I4 which would do all of very little for the cost of it. I thought one of these setups would make a lot more sense and provide A LOT of power to the wheels versus the other ones. Nothing beats a nice stage 2 turbo no doubt, but i think one of these alternatives would give the lancer a good shove in the right direction. Anyone with some experience feel free to correct me to hold my hand in this...

yes id say for the amount of money it cost to just beef up internals you could get just a normal Turbo or supercharge.

also think that these 1000+hp supra's etc run on turbo only. not both. Just "many" reasons why this setup is rare. is because its not worth the bang for the buck.

^yes, but are they not one monster of a turbo? i would want to beef up the internals of any car i'd plan on turboing just to make it live a lot longer and in my mind atleast be stronger, more reliable, etc. Does anyone have a gander as to the cost of either of these options?

for a custom turbokit around riips SDS.... you're probably looking at 10-15k for the cost of the system, management.... then on top of that the cost of new internals and having them installed. You'd be around maayyybbe 250whp for the cost of this. and power throughout the rpm band? Have you ever heard this word.... Trim? If you get a turbo just to run around 9 psi up to 6,000 rpms..... even a t3/t4 with a small trim.. would get you spooled around 2500 rpms.... that's definately low enough. if you go any lower you kill driveability because if you're always in boost your gas mileage is going to be terrible. However, if you wanted to do a custom single turbos setup..... Pistons: 400. Rods: 800. Install... 1200? Custom Turbo Setup... Let's say 4500. Fuel pump, injectors, management, tuning... let's say 1200. Spending 8100 at half the cost of a sequential, or supercharger turbo system, and being able to run up to 18 psi in a lancer and have 300 whp... or what was that, 308? ( omarboy) Priceless.

Trust me, just pick a nice sized turbo, beefier internals, management and you will be way happier than doing a sequential anything and you will have just as much whp.

At 28 psi, I estimated I had about 375 whp in my Mirage, and the guys who I keep up with, most have between 350 - 420 whp on just a single turbo. Although I personally think whp is just a bragging number (ask all those 1000 hp supras running 10s and 11s, and then ask Lancerman who has about 475 whp in his Mirage running 10s), that amount of whp would keep you happy and DEFINITELY shock the world.

10s are fookin 10s no matter how you look at it. As long as you can keep up with those cars horsepower does mean ****! Just get them to the ground and lose weight, and wamo, SUPRISE!

building a turbo kit around Ripps sds might be the dumbest idea yet? wuts the pt? if u r gonna go supercharger+turbo, u go with a roots style blower rather than a centrafugal. the blower ripp uses is a vortech unit, which is a centrilfugal which has similarities with a turbo. they both build boost as rpm rises. so to use a ripp kit and a turbo is prob running like a large turbo. u will c all ur power above 3krpm. and what do u have before that? u use a roots blower because i get instant power off the throttle. its not as efficient as a centrifugal but it has i advantages. it builds up alot of power down low. u create X amount of boost right away than tappers down at higher rpm, than ur turbo will kick in from 2500 or whatever.

imo, it would be a complete waste to run both setups. yes it would be awesome, but its far too costly (unless you truly desire to invest that much), however it will not be as much as N1te was estimating. you might as well just choose one and stick with it, it will ensure a much more reliable daily driver. since several have been speaking of supras, i have to add that they are the most overrated cars there are (maybe not as much as skylines though), they produce ungodly amounts of power, but most can't get it to the ground as well as several other things such as that ever so steep pinnacle on thier dyno charts. they are pretty cool cars, but just not the best bang for the buck, sorta like this setup that you want to do.

Twincharging is impractical and expensive. If I were to spend all that money/time/effort it sure as **** wouldn't be on a Lancer.

lol except they are one of the most mod friendly cars that exist with a bulletproof block that can take up to 950hp on stock internals.... ur right, overrated.... and yeah a lot of the high hp supras run 10's even if u throw on a hundred more horsepower, but look at the insane trap speeds.
