2011 ms3

So what's your end goal?
How big is the big turbo and don't you think that a smaller turbo would be sufficient and more fun?

Turbo Manifold

This turbo is a BNR s4, it is "the biggest small turbo" so im on the same track as you user

why not go for a small fast spooling turbo thats almost always in boost? especially in an FF car

Here is the link to my youtube if you guys want to see some progress I have made so far, right now im waiting on parts from corksport (tranny mount) and a catch can from damon motorsports to come in. Im heading up to AWD tuning in dallas Tx today, be back saturday with dyno event video.

The BNR s4 is a good choice for fun guys, it will hit peak boost at 3500-3600 RPMS, and is good for up to 450 hp and 450 Torque, The k04 turbo I had on there is too small and ran out of puff, It made 300 HP and 360 Torque before i started this build, I plan to gain 100 hp and 40 torque and thats tuned down since i dont want the block to explode.

Nice dude, what have you got right now for suspension and exhaust? Those are the two mods I'm looking at next and I've been really curious for input; I want to go cheap on my coilovers kinda cause I basically just want to not feel monster truck status, go down a couple inches but my one buddy is telling me don't cheap out on them. What do you think? Also is your k20 blown or just upgrading it for the power and selling the k20?

according to the stats, the thing comes on around 3250rpm and hits max torque at 4000rpm

honestly you would want somthing that comes into boost around 2800rpm and peaks at around 3800-4000 rpm that way you have more usable power and arnt bogging down when turning from stop signs or on tight twisties

according to the sizing info the extruder is 76mm which is going to produce a sizeable lag on the low end meaning that na cars will definitly get a huge jump on you from a dead stop

if anything you want somthing a little smaller and instead opt for lightweight flywheel, lightweight pulleys, lightweight wheels (RFP1) and any engine modification that will increase low end power and make for faster response
