The Ricer Eliminator
So, If I want 400rwhp, I have to have a ported engine? Or, is that just for the Apexi?
I don't want to run insane boost, as I have blown 2 motors in 3 years. It seems like i'll have to run higher boost with the Apexi than I will with the T-78.
Even though i'm constantly hearing of different turbos, logic always seems to bring me back to the T-78. I figure that it is better to have a bigger turbo not have to work too hard to make the power, rather than have a smaller(faster spooling) turbo have to work hard to make the power I want. I would like a little reliabilty, even if it comes at the expense of a little responsiveness.

I was very interested in the Rx-6, before i found out you had to get apexi to rebuild it...and no one in the states would touch it. I also wanted a bit more top end...so i started to think about the to4s. All the people i've talked to via PM said they love there little t04s. Have'nt realy heard of anything bad about it so far either. So, at this moment the to4s is the turbo i would like.
My buddy at Excessive motor sports (Ralph Friend) has a realy nice dyno with all the toys to go along with it. He seems to like the plug-n-play ecu. So i'm either thinking AEM (A little while after the release date...so they can work out any bugs
), or the tried and true pfc. Ralph likes the pfc, as last i heard he put down 530rwhp@22psi with it. Not to mention....i've done one standalone setup, and i realy did'nt like doing it to much. Kinda a pain in my opinion.
I'm don't know to much about the different manifolds and stuff. Whats the difference between a undivided, and divided manifold when it comes to spool time, hp, and what ever else?
I'll add the SX FPR to my list
How about Bov? I don't realy want anything to loud. Infact quite would be best......any suggestions?

pp13bnos: My understanding is that you can vent the BOV to the exhaust or back into the intake of the turbo, and it won't make noise. It only makes noise if it's vented to the atmosphere.
I got to ride in a hella powerful 300zxTT, with the bov vented to the exhaust - you could hear the turbos, but you couldn't hear the blowoff valve at all.

I'm back to the Apexi again. I would go T-78, but I need to pass emissions(with air pump). Ma. is getting tougher with emissions all the time.
I guess i'll just see how much power I can safely ring out of a stock unported motor with the Apexi. Maybe i'll port my next block.
Here's a question. Does porting the motor, make it weaker or more unreliable than unported? The only reason I ask, is that a lot of places have a smaller warranty on the ported ones.

Yeah, I was referring to the 35/40 bandwagon... I can't remember who it was, maybe Greg, referred to the mass flocking of purchasers and how you could sell a chrome ***** just cuz it's pretty... or something like that :P
Reguarding ball bearings. From what I've heard, again, from what I've HEARD, it was the turbonetics (and their knock off manufacturers) single ball bearing turbos that were having problems. Garrets have been running dual ball bearings and single ball bearings with little to no problems (from what I've seen). If anyone on here has personally crashed a garrett ball bearing turbo (single or dual BB), please post and tell us your story. I know several people that have destroyed the turbonetics (and turbonetics knock offs) ball bearing option within a month or two of purchase... JUNK!
pp13bnos:
Manifolds, i think you mean exhaust housings. Divided Vs. Undivided, well, its just that. A divided housing has a split down the middle of the exhaust side that hooks to the manifold. It runs two seperate, but parallel pulses of exhaust to the turbo. The idea behind this is that with a properly engineered exhaust manifold, an exhaust pulse would always be hitting the turbo, one after another... not losing any velocity "falling into a bigger chamber". The undivided housing is just that, one big opening from the exhaust manifold to the exhaust wheel. A divided turbo with a divided manifold (which btw is very easy on a rotary since we have 2 exhaust ports... well, most of you do
) will create better response. It has been said that if you run a divided manifold and turbo setup, you can raise the A/R one or maybe two notches and not notice a difference in lag, but gain the high end HP that the larger A/R brings... ie if you are running a cast iron undivided HKS exhaust manifold with an undivided .96 A/R on the hot side of the turbo... you could switch to a divided manifold and divided 1.15 A/R housing, make a lot more power up top and still have the same response. So the story goes...
As far as a blow off valve goes... you can't really go long. The only one I've heard of problems with is the Blitz SSBOV. I would get a Greddy Type S. It does make noise, but like stated, you can plumb it back into the air box to reduce the noise... plus this one has a threaded outlet on it so you can screw in different "horns" (which I've yet to see, does anyone know where to get these) that are suppose to let you tune the BOV sound to your tastes.

3 Rotor huh? I'll have to look into that
On another note:
I was unaware that the RX-6 turbo was having a tough time breaking the 400 rwhp mark... I may have to re-evaluate my stance on that turbo... I always heard that it was a good 450 rwhp turbo with stock twin spool up time... But, I don't own and FD so I never really looked into it.
When I go single turbo next year, I'll be going with a PT-88, which is a standard T-Frame turbo (like the T-72 or T-76), but with a machined compressor housing and a Thumper-88 88mm intake wheel on it... should make some good power. The Grand National guys are making over 1150 hp with it... not bad.
