Need Help Choosing Turbo
I'm planning on upgrading my turbo soon and I cant decide between the XS T04s or the BNR stage 3 upgraded twins. My goal is to hit mid to high 11's and i figure this might take about 400whp. I know the BNR is the more cost effective way to go but is it capable of pumping out 400hp to the wheels? Which turbo has quicker spool up and less lag? Also if i were to get the upgraded twins would it have the same problems with reliability as the stock twins because of all the vaccum lines? This is my daily driver so i need something as streetable as possible. Thanks in advance.

Hmmm to4s is a single and the BNR stage 3 is twin, the twin will spool up faster than the to4s so you'll boost faster, however you might not get quite the kind of power youll get with the to4s...what else...Im not sure about the BNR doing 400rwhp because i havent researcehed it. I have a reccomendation and its that you get a GReddy t78 or t88 Turbo kit they both have the power to do 400 HP and the t88 up to 450-500~. there will be some lag, but you can compensate by getting an HKS SSBOV and Wastegate(External) and the Greddy 3 row FMIC you'll make up for the bit of lag by your hp gains and depending on driving skills, I hope this helps sort of, but in the end it's up to you, for now all i have to say is....

I will be going with the GT35/40, myself. It doesn't take quite as long to spool as the T-88 or T-78, but it still provides a great deal more power than the stock twins.
Also, going to a single will help eliminate some of the complexities of the twin setup (vacuum lines and such).
Just my opinion

The BNR Stage 3's have been proven. Dynoed at 414rwhp and trapped 125mph in the 1/4 mile. Thats at 17psi on pump.
Ask Wargasm about the T04S.
I would get a GT35/40 or the stage 3's. I dont care about the 1/4.. I just want top end. Crazy top end.

I'm not really a big fan of GReddy turbo kits and for the price of a t-78 I would much rather get a t04s from xs. The only reason i want to go with the twins is because its so much cheaper than the single turbo kits.

I think the 412 or appx rwhp # put out by SPOautos on the BNR 3's was also not really tuned yet.. If that's the case, could probly get ~430 out of them.

Whats up all. The Stage 3's are very efficient at a low boost level. They are perfect for pump fuel. Peek efficiency is reached at about 17.5 psi. The To4S garretts reach peak efficiency in the mid 20's. Great for race gas, and helified tuning 
. I am going for 430-440 rwhp on pump fuel with the stage 3's so keep your fingers crossed...

I don't believe in spending good money on rebuilt turbos (BNRs). Spend the long green, and get brand new Japan spec Type RS/RZ ('99) Sequential Twins. $2910 from Mazdaspeed Motorsports. $2600 from SR Motorsports. Reliability will be MUCH better, especially if you open-track the FD.

?I'm very happy with the Stage 3s. All the advantages of a single at a fraction of the price. Thanks Bryan!
