ok here is the specs on this one..:stick:
the car drove in the shop with a weber 48 IDA and a racingbeat headeron his freshly streetported 13B motor for a turbo conversion
the car is a 1985
the motor is a 85 4 port 13 b streetport consisting of a 13b SE motor, using 4 port 12a sidehousings.
the intake manifold is a 91 turbo that has been welded up and re-drilled to fit the early 4 port motor.
the turbo is also from a 91 that has been upgraded on the cold side to a t4 housing with a 60 mm compressor wheel(good for 350 hp)
turbo prepped distributor, 2 MSD 6A units, Magnacore ignition wires, with B10EGV spark plugs complete the ignition system
Fuel systen consists of a weber 48 DCO thats been turbo prepped, with a nice ROTARYSHACK turbo plenum sealing it ip.
fuel pump is a stock SE unit that delivers more than enough fuel thats regulated by a mallory #4309 unit(boost refrenced)
exhaust is a 3" custom downpipe thats connected to a 3" straight through magnaflow muffler
non intercooled
this car HAULS ASS on 8 psi using 91 octane pump gas

P.S. i spent 6 hours cleaning the engine bay, i wanted to scream!!!!! :owned:

P.S.S. thanks to coldy 13 for helping me put up the pics, i forgot how:doh: :smoker: :allcho:

Engine looks very nice. Did you polish the rotor housings? Little detail work with some wire ties and doneski. What is the car in front of the lift to the left?

680RWHP12A 10-22-03 07:19 AM

yes the rotor housings are polished along with the front engine cover, and the transmission bellhousing!
the other car is a 72 rx2 thats also getting a 13b turbo conversion

Very Nice. :drool: :drool: :drool:

Looks very nice. Especially with the Red Accents.


When I'm done with IoTus's car, I'll post what I did with the Throttle cable. I made a bracket and mounted it on the carb hat. The carb hat was the perfect length away from the throttle linkage to mount the bracket. It actually looks good, and you may even want to think about making them like that!! It might save you a little extra time in the long run.

I should have his car running by the end of the week.


By the way, thanks for coming through with all the parts!!


One last thing... where did you get that piece of silicone tubing coming from the turbo up to the pipe that goes over to the carb hat? I think that would probably be better than getting 2 90 degree elbows....

79+80+84_rx-7 10-22-03 10:29 AM

you got that nice racing beat strut brace hangin over a cherry picker, lmao


nice work btw....

web777 10-22-03 12:19 PM

Do you have a BOV on it? How loud is the car? I had mine 3" straight to an ultra flow and it was fricking loud!

Gregs 10-22-03 12:24 PM

that rubber hose looks similar to the hose on eclipses running from the turbo the the IC...

Real nice work Robert. Someday I'd like to drop my REPU off @ your shop for the same deal + intercooler.

What's the anticipated lifespan on that motor?

Glad to see more people using Magnaflow mufflers.

i cant wait for the pics of IOTUS car! glad to hear its almost running:bigthumb:


i get the silicone connectors from my turbo supplier

ioTus 10-22-03 02:23 PM

You know what, i still ahve the stock turbo 90 deg. bend from part of the stock setup. we can use that as part...

Directfreak 10-22-03 03:17 PM

Great Setup,

An intercooler would be nice, but that's nice and
simple.

And that would be where? In my garage or in your car, maybe? I hope?


BTW- I'm picking up the new Alt tonite.

nlc1179 10-22-03 06:46 PM

that looks pretty sweet robert. what the hell is up with it being auto though. i would think someone like you would know not to have an auto rex. matts turbo project is sweet. i love riding around in his car. if his clutch ever starts gripping, its going to fly like a bat out of hell.

Siraniko 10-22-03 06:54 PM

its not an auto. thats only the shif knob. i think its hurst shift knob right?

firstgen82 10-22-03 07:25 PM

I like that rx2.............
hey robert, when u coming up?

XLR8 10-23-03 04:58 AM

The pics are gone now..........sounds nice though.

I'm confused---"the motor is a 85 4 port 13 b streetport consisting of a 13b SE motor, using 4 port 12a sidehousings"

So I could take 12a side housings and turn my GSL-SE 6port engine to a 4port? Would I use a 12a manifold when going carb?......so confused:)

Siraniko 10-23-03 08:12 AM

the gsl-se 6port motor can be converted to a 4-port by using the 12-a side plates or the old 13-b 4port plates. And any 4port 13-B intake manifold will bolt right up. now, if you prefer to use a 12-A manifold, there are several places where you can get the "12-A to 13-B adapter plate." Call Rotary Reliability & Racing or Powerhouse engineering (now called www.mazdacomp.com) they run appx $150.

Siraniko 10-23-03 03:16 PM

680,
Looking at the GSL-SE, the owner of that car is from R-Power right? I remember Sidepex building his engine.

looks like a TII intercooler elbow to me

fcfdfan 10-24-03 08:45 PM

Always interesting to see what you are up to, Robert.

But when the hell are you going to start selling a "Rotary Rodent" T-shirt. How is your mascot, anyway?

81projectrx7 10-25-03 04:36 AM

Yo Robert... very nice project, but when does the NOS get put in? :worship:
I can't figure out if its manual or auto like others have mentioned. What is it?
Hope there is a nice set of tires on there to control that monster!
I need that carb, whats up with the credit card machine?
