best size/kind turbo for this FMIC
 
My FMIC I have is 29x18x2.5 and I actually have this turbo coming in (T61) and I have reason to beleive that this combo may not work to good. I am and will make this FMIC fit, but what kind/size turbo should I get....im not too thrilled by the T88 wanting something better. I want to be able to do 35psi max and run normal at 15psi with good spool. Suggestions?
Jeff :D

Besides the obvious (like, post in the correct section :) ) size the turbo for the engine, then size the intercooler. Intercooler size doesn't affect turbo sizing.

So your saying having a stock turbo and that size IC wouldnt defeat the purpose? I mean im just wondering what would be a good setup, and I thought I could post this question here...

Intercoolers = Bigger are better.

HP would go up with a bigger intercooler regardless of what turbo.

35psi is ALOT of boost dude, you got everything else set up right? Injectors, fuel pump etc etc?

rx7passion 12-09-01 02:17 PM

its all about flow, 35 psi from a t88 would be different than a stockk 88 turbo at 35psi. but as far as i can tell the diamentions and a t61 should work fine. but 35 psi from that turbo i dont know about, if it was a t76 or something overly insiane you could....:)

TuRbOfAsT87II 12-09-01 02:44 PM

Well I was planning on running max boost all the time, but because this is a rotary and I havent really explored what the engine can handle as compared to the conquest tsi, Then I want to tone it down a little bit and run 35psi in big races or drags or something. As for the other mods accomodating what boost I plan on running, im getting so far what I found, but then again for some of the stuff im not too familiar with yet. Such as I want to get some stuff from www.racingbeat.com such as the race rotors and the peripheral housings, but I havent taken the motor apart yet and I dont know how many peripheral housings are in there lol. And when I read about the race rotors I need some kind of weight things to balance it out, and I need them off of the 88-89 I think.I havent decided on injector size yet.getting all the obvious good hoses and wiring bla bla bla. Apex seals or whatever. intake, exhaust and all those goodies. beleive it or not i will not drive this car after its all done until I have a immaculate leather interior in it lol. well thats the jiff

Eh...are you for real? Do you know much about rotors?

Man I'm not trying to be a dick but you have no clue as to what your doing. If you really want this kind of set up you need to have a shop do it for you because you are not capable. Just being realistic.
35 psi on a Peripheral port does not equal driveable. Your talking about a set up makeing well over 600 hp if done right.
What kind of car are you putting this in?
If you really want a motor with that much power you should go 20b. It would be a lot easier, more driveable, and more reliable to make that power with a 20b. And if your serious about what your talking about then obviously money is no object.

There are 2 rotor housings in your average rotary. There aren't any peripheral housings in a stock engine. A p port is a port modification done to rotor housings.

yeesh, 35psi on P-ports... a T88 would possibly be too small :eek:

um, moderators? anyone? bueller? bueller? i think this thread belongs in the single turbo section... granted we're being helpful and all 'cos that's what we're like, but this really isn't 1st-gen related and is probably not getting the exposure the situation demands.

but that's jus' me.

TuRbOfAsT87II 12-09-01 05:39 PM

Well I do know what im doing in the turbo area, as I do have a turbo car back-ground. And learning the rotary will not be difficult at all. And as for the definition of "streetable" streetable is an opinion not a fact or direct HP at the wheels or anything like that, if I had the money I'de make a 800hp street car, it makes no difference to me. I will stick with the 13b not the 20b, if I wanted the 20b I would have bought it you know? im going for something unique here, something original...im not going to follow in someone elses steps to get HP I want. And I have a 87 Turbo II to answer the other question. And I did post this in the 2nd gen. thread I do not know how it got here actually I will re-post it in single-turbo sorry for the inconvience, but just because what I want to accomplish is going to be difficult does not mean I have to go have someone else do it im sorry, im going to do everything by my-self.

If you go the route you say you're going, I could become a millionaire from selling you engine parts.... :)

TuRbOfAsT87II 12-10-01 08:53 AM

Well im not an idiot, so you probably wouldnt make $0.01 off me:eek:

I think he means you'll be mulching engines on a daily basis.

High boost on a rotary needs some severe tuning. One good preignition and thats it. ZOOM ZOOM BOOM. :(

rotorhead 12-10-01 10:27 AM

nobody here is trying to be offensive... we just don't want to see you go through so much work to have the darn thing explode on you! honestly, i know i'd rather hear the cool success story you'll write when you finish. but i'd suggest doing a LOT of reading up on the rotary first. its a wee bit different than a piston engine. talk to the turbo guys, they'll know from experience what you can work with. and as far as streetability, i think everyone might mean that below 4k, you'll have no power, and above it will be a rocket. great on the track, but a supreme pain in the ass in stop and go traffic.
good luck!

TuRbOfAsT87II 12-11-01 03:09 AM

Well, I know that I do not know everything that I need to know, but im not going to buy something and throw it in before knowing the consequences and procedures, and what else to do to accomodate for these modifications. I appreciate you advising me not to blow her up after I finish it lol. I'de like to atleast get acknowledged into a magazine when Im done...but my cousin will be in one soon after his car his done...damn him.
