Just curious, how long do you think a Peripheral ported engine with a T66 turbo would last. And What would be some drawbacks to this. Im doing a lot of research on setups and i might build my engine as well as a seperate "prototype" engine so to speak which will be a peripheral ported engine but will be turboed. I dont know what turbo would be good to run with this setup, but i would say something like a t66 or larger (T04R/T51). Im curious as to what the specs might be on it such as power, etc. I would also like to know what you guys think i would need for this setup to run properly.

Search around. Judge Ito has a thread about one. It made something sick like 630 to the wheel on low boost.



Definately not a street application though. BTW, you are gonna need something alot bigger then a T66 to reach the full potential of the motor.

yeah, the pp has a lot of overlap so the key is low exhaust restriction. the ideal setup would be BIG on the exhaust side, either 2xt4's or a big t51/ta45

Those PP motor can't idle can they?

they have a really lumpy idle at about 2k



mike

For whatever its worth to you, I've seen two drag only cars turbo boost the PP. One was Sammy Benitez in the Mothers Performance 91 RX-7 (20B 7.4 @ ?) And the new project on the scene, Jose and Carmelos "El Duke" RX-3 (13B 8.7 @ ? on an easy pass). The RX-3 looks to have more than T-70 and the RX-7 turbo is so big it could be used at a meat processing plant! (lol) Sammy operates a performance shop & store on rte. 46 in north NJ, look him up. Good luck!

Yeah one of those guys is who Ito was reffering to I believe

do you think it would be smart for a street setup? It wont be technically the "daily driver" more along the lines of harcore racing on the street. Its just a prototype and im just wondering. If its not a bad idea, im going to do a bunch of things.

I think it would be better of to bridgeport it..

on the street you have a turbo so you can leave the porting mild and still make good numbers, if you pp you need to basically go all out other wise, it wont make power or be very streetable. ive never driven a pp, but i have driven a bp and you need to keep the revs over 4-5k before it will cruise smoothly.



mike

Not a street application. The guys mentioned above that are running a PP turbo setup have tube chassis all out drag cars. Just look at the times they are running.



A 8 second car doesn't belong on the street.

There is middle ground, cross port. To me if it drives it is streetable, some people think BP is unstreetable. Just depends on the person, all I know is a PP wouldn't lose that much!

cross port?

They drill a big hole into the rotor housing and match the intake manifold. I'll look for some pictures, there were some on here somewhere.



Over here they sell the manifold and the custom lower intake manifold for 220,000 yen. About 2 grand.

isnt that a pport?

Drill hole to match STOCK intake manifold?

streetable: you can give the keys to a normal human and expect them to dirve it without more than 2 instructions



mike

The crossport that I saw still had all the stock intake runners, plus two quarter sized holes drilled into the rotor housings. On most PP there is only one intake going into the rotor housing, this still has the stock one on the plates. Damn I need to find some pictures

ohhh a partial PP

Partial PP/crossport same thing, been in Japan to long. It's not PSI it's BAR, it's not turbo it's turbine.

I agree definatlly a brige port. https://www.nopistons.com/forums/pub...#>/BURNOUT.gif

How loud would the bridge be with a nice turbo, say t51

~110dbs (I'm guessing) (remember, dbs increase with logarithms, for you math guys)

Do you even have a car Nobuteru?Dont take that the wrong way,im just curious.PM me if you dont want people to know.

No, i do, im working on my turbo FC. Its off the road right now so i dont have to pay for insurance, etc. Im just asking alot of questions because i like to know as much as i can. Some of the things might seem far fetched, but i dont back out on plans. Chances of me running the PP turbo is more than likely not going to happen, but i just wanted to know the success, stats, etc of running that kind of setup. People seem to reccomend the bridge, and last night i heard my first brisge up close in person and i absoulutely loved it. I do plan on having at least one spare engine, and i will most likely have one bridged and the other one with a large street port. I want to use the street ported one first, use a decent turbo which might now be a T04B with a 1.15 turbine A/R and a compressor side of 60, P trim, divided housing and since its a garret turbo, i can always make it bigger. If i dont go with that, itll probly be a full T4 turbo, and ill go from there. I dont know if i should or even could go with the kind of power of the T51 because im not sure if the 13BT would hold that much power being that i heard when you start going higher, the housings etc wont hadle it. I was planning on using the street ported 13BT with this setup for a little while, then maybe moving to an 13BREW and using a much bigger turbo. I just wish i knew a way for the 13BT to hold that kind of power because the REW swap seems like its gonna be more than what its worth. If you guys know any ways, please let me know.

no more thoughts about it?

PP would be really hard to tune also, would need an great tuner.

do you? no...shut up







dude a PP like everyone else has said is rediculous as a street car....like - its track car material....i mean you can bring it on the street every once in a while



but dont ever expect something like - hey lets go to get some groceries in my PP --- ull most than likely have it pop on the way

That is totally untrue , A bridge port , or pp could be streetable , it all depends on the individual and how big your NUTS are, I myself drive a half bridged 7 with a T51 turbo (1.22a/rturbine ) as a daily driver and its completely streetable . https://www.nopistons.com/forums/pub...1047683473.gif

well yes they are streetable...any car is....its all a matter of do you really want to drive that car on the street everyday making huge noise smoke and getting 2mpg?

damn, 2mpg?? lol thats a little harsh on the wallet. Like i said, just some ideas. As of now, 99% sure im going with street port and T04 and some specialty items which shall remain nameless until it is completed.

2 Mpg ?, thats a gross exaguration , smoke ? , what smoke ? , leaves me to wonder if you even know what you are speaking about , have you even seen or ridden in a "big ported" turbo rotary. https://www.nopistons.com/forums/pub..._DIR#>/sad.png

you dont smoke at startup like every other rotary with no cats?



yes 2mpg is a gross exaggeration....but its pretty close too it...



i know what "i am speaking about"....it leaves me to wonder if ur not letting yourself realize that a pp big turbo car is streetable but really isnt smart...punch the gas in rain, spin

"punch the gas in the rain and spin" most turbo 7's can do this stock

hehe true

they had the 79 factory race car at the historics yesterday, mmmm it sounded soooo good, and yes it did smoke.



i so want something that revs like that



mikw

Actually , yes my car lets out a very light puff of blue smoke on initial start up which clears up almost immediately after it starts to heat up , this is because I use premix in my fuel.

"Punch the gas in the rain " , this is not only DUMB but irresponsible, I did that once when my car was stock and ended up at the side of the road , luckily there weren't any other cars in sight and I didn't hit anything.Weather you ar driving a stocker , a mild or wildly modified RX , a CICIV or a mimivan a lot of responsibility comes with driving.

When I punch the gas on the dry asphalt with 325 /35 /17 Pirellis in the back I get scared because the car begins to " dance " , I don't even want to think about what could happen in the rain.

If you are giving someone advice , please try your best to be truthful and accurate with what you say , If you don't know then say so, as I said I drive a Half Bridged 13B , with a massive TA51 on it every day , I even go to the market with it , my biggest problem is the ACT Extreme clutch which is a bit fierce in traffic , but hey its a modified car , you got to give a little here and there, one of these areas is your gas mileage , it gets worse ,but its alot better than 2mpg's .You have to decide what you want , there is no Free lunch in the world of modified cars , period.I bit the bullet and went in head first and am happy to say that I love my car a whole lot more now and no mild ported street port can even think about coming close to what my baby spits out at only 10psi (for now , I hope to got to 28psi soon) !!. https://www.nopistons.com/forums/pub...DIR#>/cool.png https://www.nopistons.com/forums/pub...DIR#>/cool.png

DuMaurier 7 let's see some pictures!

You are only running 10psi on a half BP, why so low?

Only 10 psi because I am breaking in after replacing those SHITTY HURLEY seals with the good ol MAZDA 3pc ones , as for the pics , I can never get those posted , but I am also a member of the EVIL forum and I go them posted there , i'll get the address and put it up here. https://www.nopistons.com/forums/pub...IR#>/smile.png
