Title: FD3S Non Turbo Engine??
Post by: shafster on October 23, 2008, 10:52:12 PM
i was speaking to a mate of mine who is a breaker and he told me he had a non turbo fd3s engine in. he was confused as it was a non-turbo engine and he\'d not seen one before.

i\'ve never heard of this before either

so, does anyone have any ideas on whether the fd ever had a non-turbo engine fitted to any of its variants? i thought they were all twin turbo\'s

The simple answer is no.
The FC3S had turbo and non turbo models but the FD always came with twins :D

There was an ReAmemiya FD which was for sale in the back of one of the magazines with the normal 13bRew in it but it was non turbo.  They are out there but never where standard of course :Giggle

Yes it is twin turbo (didnt I say that already?), the Turbos and control system are the same, but the engines are slightly different - what I dont know, apart from the exhaust ports.

Maybe other peeps on here can comment further....

On the 13b-re from a cosmo has larger runners in the LIM so can flow more.
Title: FD3S Non Turbo Engine??
Post by: BlitzBoy on October 24, 2008, 02:28:07 PM
Intake runners are bigger,But the Plenum is an older collector design wheres as the FD uses a Dynamic pressure design, Intake ports are bigger, exhaust ports are smaller then the REW, this was done to give more torque but less outright bhp, the bearings are better on the REW then the RE I have been told but need to confirm that.
So if you going to use a RE make sure you mod the exhaust ports to the same size as the REW.

The main benfit of the RE is that the plates have more meat and are bigger ports then the REW plates

and to be honest a modded REW and a modded RE produce the same amount of power

Garage R in Japan had a PP ported non turbo FD forsale a few years ago.  Basically the 13B without the turbos.  Looked odd as hell as so much empty space in the engine bay.  Cant really see the point in it myself but it can be done.

i\'ve seen picture of a PP 13b in an fd with some massive webers on top somewhere (no turbos of course). i\'ve always liked the idea of carbs on a rotary, something \'pure\' about it!

Post by: Kevin on October 27, 2008, 03:07:32 PM
I would PP & carb a non turbo FC but wouldnt bother with FD personally.  I know what you mean about pure though.
