Top Feed Rail In R33 With Stock Plenum..yes It Can Be Done

[Dose Pipe Sutututu]

yes that rail will be a little harder to fit, but what size injectors (height wise) did you buy?

[SkudR33]

3/4 length injectors from deatschwerks without the cap. The bolt is like double the size it should be and the guy from rocket industry reckons I got no choice but to cut the bolts and bracket.

there's your problem... if you use that rail you will need 1/2 length.. if you used the rail I used you can use 3/4 length

FYI the aluminum adapters that come with the Aeroflow Fuel Rail kit may not fit with the O-rings as provided by Aeroflow. They are simply too fat. You may need a smaller O-ring to overcome this problem. I am in the middle of working this out at the moment!!

That is 100% correct. Mine didn't fit at all after many attempts. I just went to an auto store and bought some o-rings!

So after being recommended to go top feed rail, injectors ect instead of buying side feeds...

Im now looking at the issue of the FPR.

Scotty sells a stock FPR adapter, has anyone used or know of anyone who has used it?

Would it be my best option given that the only reason Im considering an aftermarket Reg because of the new rail.

I've done heaps of searching but have only found people going all out with new rail and FPR

[Pauly The R33]

I got an adjustable Sard Fpr and sourced a gauge for it to set me back about $160 all up. Anything Jap and adjustable and you should'nt have an issue

I used Scotty's FPR adaptor, and it works fine.

Two years onwards on E85 and sometimes 98RON and the injectors are tips are spotless... nevertheless will get them cleaned and flow tested just for science. 

Since the upgrade, I've fitted a Radium Fuel Pulsation Damper (FPD) as well as upgraded to a Turbosmart FPR1200 to stabilise fuel pressure and pulsations/oscillations. Has made a significant difference in the VE table, I'm now able to smooth it out where as before it had certain holes in it where it needed heaps of fuel.
