Single turbo guys...if you could do it all over again...what would you do different?
As many as you guys know...i'm getting closer and close to becoming one of you. (I realy can't wait
) Over the years, as i've built different cars, i've found that I usually end up buying a part. Then the part does'nt perform the way i want it to, or something...I mean it works, but you wish you had something else. So my question is, what would you have done differently if you could do it all over again? I mean like, instead of buying a to4e, you wish you would have bought a t04s....or a T-78 vs a Rx-6....you guys get my point right? It just does'nt have to deal with the turbo...but the entire single turbo conversion. Fuel pumps, injectors, fuel rails, bov etc...
What i'm looking for is to make 400rwhp on pump gas. CJ

If I had it to do over (which I will ), I don't think that I'd do what everyone else did / has done / will do. Go custom man... everything you listed was a kit. Do some research on what you REALLY want, then pick out the BEST **** you CAN'T afford... then eventually get it.
Like, if you're stuck on which fuel pump to buy, the $300 one that will do the job, or the $500 one that will support your power, plus a lot more, buy the expensive one.. cuz you know as well as I do that once the horsepower bug has bitten you, you can't get enough. You'll be upping the boost, or changing fuels, or switching out turbos... buy the BEST supporting hardware there is.
Buy the best ECU on the market... don't just SETTLE for something suffficient.
Don't run someone else's fuel map in your ECU. Tune your car, or have it professionally tuned with a wideband o2 sensor.
Make oil lines and fuel lines out of QUALITY SS braided lines with AN fittings.
Do your own work. You'll learn your car. You'll save money. You'll have fun. If you aren't interested in learning or saving a buck, pay a GOOD shop to do the work for you.
This isn't probably what you were looking for, but this is what I would do / am doing....

Well I haven't done it yet, but if I were going to, I would NOT get a T78. Why? Although it's probably one of the best FD turbos out there, everyone and their brother has one. You look in a magazine, and there is an rx-7 feature. Don't bother reading it, you know it's a T78 FD putting out 420-450 rwhp. Like Kurgan said, go custom.

Well I'm not saying it's a BAD choice, it's actually a very good choice to use a T78. I'm just saying that why I personally would not do it. Same reason I don't want to own a mustang, a cavalier, a civic, etc.

If i could do it over again, maybe I should have gotten a bigger turbo. Or if I had enough money and time, I would fly over to Japan and pick up a TD06-25g or an RX6B. It's ok though, I'm very happy with the set up I have now.

the innovative dual ball bearing T66 based turbo
I have gone through 2 turbo size changes. TO4E, TO4S, and next is the T66BB. Some have sugested that I go for the T70, T72. Maybe I will end up there eventually? I have learned allot on the way so I have no regrets.

So far from what i've gatherd is...
Big fuel injectors and lots of fuel. 850cc, and 1600cc with a realy big fuel pump. Perhaps even upgarded fuel lines. What size of fuel lines though?
make all lines out of Aeroquip fittings/line, that are oversized. (I would have done this anyways.)
Aftermarket ignition- I allready have a HI-6 laying around, so i'll probably use it.
Any advice on a fuel regulator?
Any advice on either to build my own turbo kit, or purchase everything seperatly?
At this point, I know the motor will be ported too.
Thanks, CJ
Also, should i get rid of the profec-B or not?

I agree with Kurgan. I have bought parts that I needed (turbo) and customize the rest.
Even though customizing and fabricating can be fun, it can be a pita if you are busy with work and other things in your life.
A bolt-on kit will help the ease of fabrication (if you're too busy or find it too challenging) and time.
Looking back, I would've gotten a kit to save time since it took a lot out of me to fabricate on my free time (hardly any recently).
Customizing or fabricating your own "turbo kit" or fuel set-up requires PATIENCE and planning (getting the right parts, finding the spec'd parts, finding out lead times on parts, etc).
You'll benefit by learning a lot, from details to basic concepts.
Pre-built "bolt-on" kits can save time and the work. If you're a turnkey guy, a turbo kit is an obvious choice. I'm sure you'll be just as happy if you select the right kit.
You can learn just as much, but you're not required to get into the details with a kit.
No, keep the Profec B.

Keep the profec B or trade me for my AVC-R 
Get an SX FPR
-10 AN lines from the pump is almost overkill in any application. I would stick with -8 or -6, but thats just me. Plenty of FCs out there making over 400 rwhp with the stock lines though...
850 primaries is a bit overkill, but can be done, but you may lack idle quality (or it may be very hard to get a good idle). 550 primaries and 1680cc secondaries is more than enough fuel for any of the turbos that have been thrown around in this thread... except maybe the T04R KAI, dunno about that one...
If you wanna be one of the 10 single turbo FDs at the next meet that all have a T78, go for it. If I were to choose a kit, I'd be going with the RX6 from APEXi.
What ECU are you thinking about?

The Ricer Eliminator
Hi guys, i'm new here. I'm weighing which single to get. Either the T-78 or the Apexi. I've heard that the Apexi doesn't have the top end of the T-78. Is that true? Basically, i'm wondering if anyone has a clear knowledge of the differences between the two.
I would like the usual 4oohp(more eventually) at the wheels.

If you want the top end of the T78 and the spool of the RX-6 get the GT35/40.. according to poweraxle it is a good mix..
I wish someone had a dyno char for one already!

I'm honestly a little scared Garrett right now. I've talked with a few people that said the bearing cartridges heat up VERY easily. I was pretty interested in Garrett prior to those conversations.

heres my 2 yen
1. the profec b is the simplest boost controller on the market, it works really well.
2. the apexi turbo basically feels like the stockers, the wastegate is open @10psi and 2k rpm, and the new kits fit with the air pump. its will make more power that the stockers, 310rwhp @10psi. they are not water cooled so you dont need a radiator you need a bigger oil cooler.

Is it possible to make 400+ rwhp with an Apexi?
If you want 400-450 rwhp, get a T78 or a T04S. Those turbos should do it fairly easily and they are perfectly suited for a road course (provided they are tuned properly).

The apexi turbo is very capable of 400rwhp on pump gas. I only made 365rwhp but did make a nice 352rwtq, and have since raised my boost to 18psi. However i'm still learning how to tune for better numbers "safely".
