did all stock rotary 95 rx7's come twin turbo?

i KNOW at least 1 person on this board will know....

 

Yes they did, Pretty freakin' cool huh. Too bad it was the last year for them those cars are sweet.

oh well, i lost the bet... i thought some of em came single turbo. a guy at school has one, he told me he runs mid 12's, i told him i wouldn't race him...

edit: until i get the z06...

 

yeah from what i know the newer years of them could only come non turbo , or twin turbo..

single turbos would most likely be on the older versions, or newer versions converted to a bigger single turbo..

 

I was just wondering (i'm not an RX7 expert) but is the turbo on a rotary engine the same as on on a normal engine. I thought I read some where that the turbo was in something like the transmission ??? or something like that. If I could just get a reply out of RX7Speed that would answer all my problems.

lol who ever said the turbo is in the transmission is an idiot. It's exactly the same induction on a rotary as it is on a reciprocating engine.

 

Thanks, zerotosixty I didn't think that was correct but I just had that thought in the back of my head bugging the crap out of me, you know how that stuff is.

yeah, I hear ya, especially when you can't find specific answers. Happens to me all the time when I'm trying to find equations for my physics courses lol

 

damn it you found me out


just shocked we have ANOTHER RX7 post


and to answer your question yes ALL cam with twin turbo stock

in 87 when they came out with the turbo stateside it was single only making around 182hp at 180tq

in 89 (still a second gen) they made some imporovements and upped it to 200hp and around 190tq

then in 92 no US rx7
93 they cam back with a vengance though

all twin turbo 255hp and 215tq
and only 2700lbs
oh yeah R1 package will handle just as well as the new z06 vette.... and this R1 was only made in 93 ....






I want one

 

after 93 if you ever find a stock non turbo rx7 I would like to have it´s addy and how much it cost cause that would be the first one I ever heard of

 

the turbo works on the same theory that piston engine turbos do

but they changed things around with the second gen turbo (don´t know a whole lot about the twin turbo setup on the thirdgen) there was a twin scroll on the exhuast side so at lower rpms it would kinda be like running smaller headers.... this way it keeps the exhast gas velocity up helping to spool the turbo (faster your exhuast gas is the more energy it has when it hits the turbine) then at a high enough rpm it would open up a seond scroll section to allow for more flow and since the turbo is already spooled up your not going to get that turbo lag you would by just bolting on a big turbo.

it was mazdas way of making the best of both worlds


small turbo by allowing quick spool up
and large turbo by allowing more flow throughout the turbo system reducing boost and hp robbing pressure inside the exhuast stream.


also since the exhuast port on the rotaries allows for a really strong exhuast pulse they changed the turbine blade shape


most of the turbines are shaped something like this (

yes that ( is the shape of the turbine and the exhuast gas hits it at a right angle like so ( <<<

on the rx7 turbo since the pulse is so strong (almost instant full open exhuast port rather then a pistong motor with a slow opening exhuast valves) it would have someone the same shape but rather then being fully curved it would curve the top section of the turbine blade but the bottom where the exhuast would leave the turbo is just straight.

this was also doné to help relieve pressure in the exhuast and help the turbo spool up quicker....

mazda did there work on the little turbo motors on these cars


hence why I am buying another turbo motor


check sig

 

How much did those cars go for?? The Twin Turb model

 

a simple yes or no would've been fine....




j/k thanks for the info

 

depends on year and be it touring, base, r1 or r2


book for a 93 rx7 with the R1 package is around 18k in perfect shape


but you can find them for around 12k-20k
