Greddy Plenum Clearance Issues On An R33 Sedan

[Kandikid]

Hey People

Just finished pulling the engine out my coupe and dropping it into my sedan.

Problem is because of the diff shape of the fuse box, the stock TB wont fit (pulley fouls on it fuse box)

Im not using the std greddy adapter i had a slim line on that was machined up, so i didn't have to change the throttle cable.

Can be seen on the front of the plenum

Now before i go off and buy a genuine adapter,
i want to be sure it will actually clear it? (every one ive asked from all the places ive spoken to so far, just tell me, "coupe and sedan engine bays the same" and well thats not the case.)

OR

Can i just bolt an 80mm throttle body straight on? without catching on the fuse box? (coz ive found a nice black one to match the plenum.
and if i do this should i need a retune (i know i prob sound like a retard, but it make sense to me that if im increasing how much air gets taken into the manifold, then the values are going to change)

thanks, and hope this makes sense

if the std throttle body doesn't clear the 80mm probably won't either, have seen a few converted cars with the throttle body on sideways so the cable pulley was on the top

Would it work with the std adapter? Mine has the normal adapter and I still run the stock cable

I dont know if the sedan will work with the standard adapter.....thats what i wanna know before i buy one lol


I might try flip my adapter round and see if i can mount the TB on top, just not sure how that would work with the cable pulling on an angle, it might come out of its rail on the pulley when on full throttle...

Using the standard T/B on my Stagea - managed to move the fusebox a little and removed some surplus material so pulley doesn't touch.

I did manage to flip my tb and it fit, will just have to put a clamp on the cable (peddle end)

but still not to keen on the angle that its being pulled at...

KiwiRS4T - would it be possible for you to get a few pics of what you did and post em up for me to have a look see.

thanks

Just cut a piece out of the bottom case - the lid is unchanged but removed for the photo (must clean my engine bay!)

oooh kay, wish i'd seen that before i pulled the adapter off and cracked all the powder coating -_- lol.

I'll give that a try tomorrow while im home,


thanks
