Recommended twin turbo setup?
Hey guys,
Long time reader, first time poster I'm in the process of getting rid of my evo (just waiting for the check to clear!) So, essentially I'm on the market for an FD come springtime, but trying to source/order parts while I don't have car/insurance payments.
Enough wasting time. I'd like to setup an FD for the track, and would like to keep the twin turbo setup. However, I've yet to find any recommendations on upgrades (yes I searched, but came up with nothing). Can anyone offer advice on this? I'm not looking for some insane numbers, I'd hope to hit the 350-450hp mark with all supporting mods. Any help is appreciated.

IMO, I would stick with the stock twins for a while. If you are building a track car, you'll have more to upgrade other than the turbos.

Like Mahjik said, there are many many things you need to take care of before you think about upgrading the turbos (like buying the car just kidding.) To support 350+ hp, there are fuel mods, engine cooling, ECU upgrades, and lots of other things to consider.
That being said, if you want to retain the twin setup, the most widely used option is the BNR Stage 3 twins. They put down more than enough power for the track.

No doubt in my mind I'll need more This wouldn't be my first build, but first with track times in mind vs an aggressive street setup. I guess you could say I have the car mapped out overall in terms of suspension, aerodynamics, braking, fuel, safety, blah blah blah... there's just a few area's that I'm stuck on. Turbo's, are the main thing I realize I know nothing about. Looking at different sites and seeing the xx A/R, xx trim is almost another language to me.
The only issue I have with stock twins is lag, I'd prefer to go with something ball bearing (unless the lag isn't as bad as I have heard). When do they typically reach full boost?
Another reason I'd prefer to avoid them is if i'm not happy with 350rwhp, all it would take is higher boost, and a new tune. Or run separate maps for street driving vs aggressive. I have a feeling this will be the case once the build-up time comes.

Also, keep in mind that a ~350rwhp FD and a good driver can deal with C6 Vettes on road courses. Its a different car and doesn't require the monster HP numbers which other cars rely on....

Hmm. My understanding was large singles were used more for straight line / highway runs / dyno queens. I always worried that having a large single while taking a turn could spool faster than expected causing an unexpected loss of traction. Granted that throttle control will also play a big part, but I'd always prefer to be safe than sorry. If this isn't as big an issue as I think, maybe I will go the single route.
A buddy of mine in thailand recommended the hks t51r if I went single... but isn't that setup made for higher numbers? (ie, 600+?). I've also heard good things about the gt35r... I know these work wonders with evo's and 240s... but how do they fair on an FD? Would anyone recommend these over the BNR stage 3 that vegas recommended?
Sorry for the barrage of questions, but thanks for the great info

Is lag an issue? Sure a little. However, on a road course, you don't spend a lot of time in the lower rpms. That's basically one of the keys of being a good road racer is the ability to keep your car in its power range all around the course.

so if someone wanted to run a single turbo for lets say autocross where the mid an high rpm's are usually maitained youd still want a turbo to be able to react at low rpms just in case.
so what im asking is what would be a good setup ie... boost controller, turbo, down pipe, etc....

Autoxing and road racing is something completely different. With autox, you won't be in the high end all of the time, the tracks are too tight for that. With road racing, we're talking about actual race tracks, not cone courses.

I'm grumpy tonight so I am gonna say it: man you didn't search crap.
There is TONS of info in here covering the exact things that you have been asking. So far your q's have been very general so a quick search would bring up much more info than just creating a thread. Upgraded twins pros and cons?, singles too laggy?, what turbo(s) is better suited for my application?... It's all here.
Ok now that I busted your ***** here are some links:

Junon, click the dyno link in my sig. I was running BNRs in parallel, so they were laggy. BUT, you can run them in the stock sequential setup and have a killer powerband. At $2350 they're inexpensive, relatively speaking. You can make 400 rwhp, with 3000 to 8000 rpm power. I wish I would have run my BNRs sequentially, I would probably still have them on the car.
Otherwise, for your application I think the GT35R or 500R (35R variant with higher boost capability) are good choices. If you go much bigger (T-66/T04R/Greddy T-78/HKS T51R etc) then you are looking at more of a straight-line car with poor sub-4000 rpm spool, which won't realize it's potential without c16 race gas.
