E85 gains with vq35de?

Hi everyone, 

Just bought my first Stagea a few days ago, a 2005 350rx.

Just wondering if there is anyone here running E85 on the NA VQ engines, and whether there is much gain to be had?

My last car was a turbo mx5 which was running E85, and that saw noticeable gains.

 

My to-do list of mods will include (but are not limited to):
-plenum spacer
-z-tube intake
-exhaust
(any other easy recommendations are welcome. don't want to go too expensive)
 

 

Thanks,

Nic

Ok well then you could pick up a few KW but given the difficulty of ensuring a constant supply of E85 you would probably want to run a dual fuel set-up which may make the whole project uneconomic.

On an NA motor designed for 95/98 it'd be a bit of a waste as you'd be increasing your fuel consumption and cost (in comparison to running 98) for zero / absolutely minimal benefit from the extra octane. There are a few people around that have done this kind of thing on the turbo models but on a stock NA the drawbacks and cost significantly outweigh any benefit that you could expect.

On the other hand if you are planning on fitting forced induction or going for big compression at some stage it would be a well worthwhile bit of work!

Your list of to do mods doesn't include an ecu or piggyback... So by the time you do that plus flex fuel, it's not going to be a cheap exercise for very little gain.

Do a proper exhaust, use the E85 money for exhaust manifolds (coz they're cool).

      ugently need expert / experienced opinion

      By GTSBoy · Posted

      There are certain tasks, like replacing head gaskets, where it is very much best to already know what you are doing, and if you are not already an expert, then the next best thing is to have an expert around to help it get done. Little annoying checks and steps that are easy to forget or not interpret the results of properly, etc etc. It is hard to convey that to someone as a lesson prior to taking on a job, because there can be a whole list of "if you see this then it means that", or "if this is what you find then you will need to do these other 4 steps first". All the little bits of knowledge around sealant choice (ie, sealant at all? or no sealant? sealant only in certain parts of the gasket? sealant for this type of gasket but not that type of gasket? etc etc) cleanliness checks and methods, surface straightness and finish checks and methods, etc etc, all combine to mean that people who have done many of the same type of job will struggle less to get a good result than someone who hasn't done it before. I've been around this stuff since forever. But I will still consult with my expert(s) before taking on the big stuff with higher risk profile.

      Well if I end up having to do the head gasket I will certainly find the necessary tools and instructions before beginning... Let's hope it won't come around.   Definitely. Depends on the job but I think "if you want it done right, do it yourself" applies almost every time

      Can you at least move to a location without so many ladders, black cats and mirrors precariously propped up ready to be knocked down? Or buy yourself a 1 ton bulker bag of salt to drag around with you. Just, you know, sling it over your shoulder?

      RB25 Oil Pump Regulator Washer???

      By GTSBoy · Posted

      Meh, what's the worst that can happen? If is is supposed to have a washer, and: the spring retainer seals reasonably well on the surface, maybe just allowing a little bleed of oil out, and the spring does not coil bind when compressed that little extra bit, then the end result will be slightly higher relief pressure setpoint, and no other noticeable effects.

      Weirdly I see a flat washer on aftermarket pumps but as you said it doesn't seem like new OEM pumps have it. EPC doesn't break out the regulator as a separate component either. I'm guessing if the pump came that way it's safe to use as-is.
