Big HP with Twin Turbos
Hey People, I need to know something. I have a 93 base model Fd3s streetported. I want to know if there is anyway I can make BIG hp with a sequential twin turbo setup. Any type of twin turbos on the maket that make BIG hp?? I love the way this car feels when i get boosted at higher RPMs as well as acceleration at low RPMs. Any advice will be helpful.

Do a search first this topic has been beaten to death.
As for your question the BNR stage 3 set have made 425rwhp in non sequential form if you left them in sequential they would make less. Check out GoodfellaFD3S he has them and swears by them. Your stock turbos should not be pushed pass 12psi or they will have a very short life.
There are a few aftermarket twin tubo kits that look now were near the stock set up. But I havent seen a good write up on there performance to say if they are good or not.

All the answers to your questions shall be answered by clicking on the links in my sig
I consider 500 motor hp/400 motor tq in a 2650 pound car big power
Edit: I run a parallel setup but seq should not lose much. An owner had the sequential setup but they were having boost problems on the dyno (go figure, lol) so they temporarily wired the setup non-seq (but with all the restrictions still in place) and the guy made similar hp at a similar boost to what I did.

well i consider 500+ hp big..in this car anyway. Goodfella, those numbers are impressive (to me) for twins but non seq. are there anyways to take two mid sized turbos and make them seq.??? custom fabrication?? hell, i don't know.......I just don't want to part with the sequential setup because i find it more fun to drive than a single

'heat from twins?' care to elaborate?

Meant the extra vacuum lines which cause excess heat in the engine bay due to lack of moving air and heat soak. He wants to keep sequential twins is what it sounds like, and for the numbers he wants to sustain, thats pushing it.
I personally don't see the point in running parallel twins. Just drop a big single in and be done with it.

This means you can run a tremendous amount of boost without killing thrust bearings.... this was in the add for the bnr stage 3.. it never says how much boost they are capable of holding without any problems.. just wondering...where is this guy located at???

Don't get me wrong, there is nothing wrong with a gt35r, dual bb t66 etc for the street. It's good to have options.

You'll also prolly want a ported engine to give a good powerband at that boost level.
Basically, parts and labor you're looking at ~$5000 in parts, lots more in labor, and that doesn't include the engine at all. Don't forget the appropriate brake/suspension mods to handle that kind of power. Budget $10k to $15k if you want to do it all the right way.
I've spent almost 7 years getting to this point. It doesn't happen overnight

More potential hp wise, YES.

Turbos for turbos, I would bet a single set up is pretty darn close to the BNR's. As price goes.Now I am not talking about fuel, spark, ECU, or drivetrain. You would need this with both. A-spec sells a non ball dearing kit for $2300 wich might lag comparably, but would have more potential in the long run. Keep in mind this includes a down pipe, I would hope that you would whant to get rid of the stock precat if you decided to run the BNR's, add in some kind of intake as well, for the BNR's.
So lets see.
Single kit includes:
Turbo, down pipe, wastegate, intake, oil and possibly coolent lines, and neccesarry gaskets to install.
Price: anyware from $2300-$3500+
BNR's $2350 with a good core, Intake $200-500, down pipe $150-300,New gaskets $100.
About a cost of $2800-3250
I can see that the potential of the single setup would be greater. The heat issue the previuos poster is refering to is all the castings that are involved with the stock manifolds tend to retain alot of heat, were as a good desighned single can have quite a bit of air movement around it, then add some exotic heat sheilding at an add cost ofcourse and you can get the temps down futher than you can with the twins.
Just my .02
Dont get me wrong I have yet to drive in a single turbo car, wich I will be driving my own shortly. I made 348 to the wheels on stock twins seqentially, and it was a blast to drive around town. I just needed a change.
My argument is soley on the cost issue.

Exactly. I'm hoping for around 340 on the stock twins running sequential before I go single and I really like the setup, but they just can't compare to a single setup, it may be a little more money in the beginning, but you'll get more potential at it down the road when you want growth, whereas its harder with twins.

so it would probably be a goo idea to just go ahead and do the suspension, brakes, order the engine managment, the boost controler, fule punp, injector, and like a turbo timer first before i go out and get the bnr turbos.. wheres a good place that would tune the car with car instead of just some shop that has a dyno and so called tuners... and if you know a shop that would tune and maybe even show me whats going on with the car...llike would let me stand around and watch... so i could learn a ffew things... that would be even better...

Don't worry be happy...

After looking at many Dyno graphs of singles... I came to the conclusion one would have the most fun (in the street) with some of stage 3 BNR's sep up sequentially.
I may head that way one day... Because a single is certainly out of the question (I live in Cali)
