Does ISR make good quality fuel injectors? I'm also curious if they are compatible with the Radium top feed fuel rail that I bought. I'm looking to buy some for my RB25det http://www.isrperformance.com/isr-performance-top-feed-injectors-750cc-set-of-6x/ and was wondering if this would be a good purchase. I'm shooting for ~400hp.

Yeah they look like they should fit no problem. 

I would think about getting something a little larger though, around 1000cc just to keep the option of E85 available in future. While those injectors can do 400hp on E85, they'll be close to their limit at that stage. 

Sorry can't say if those injectors are good or not, never heard of them. 

A set of Injector Dynamics ID1050x Fuel Injectors are only about $100 (USD) more then those ones and are a proven thing, I'd be looking at going with a set of ID1050x.

As as general rule I do not recommend buying any injectors that lack a diffuser plate. Also if you are concerned about transient fuel tuning you want to avoid the ID injectors, if you talk to Adaptronic they have mentioned that the wall wetting effects are much stronger with the pencil spray pattern used on the ID injectors when used in 4V DOHC setups because much of the fuel goes straight into the divider between the valves.

If you want to run E85 at all just go for the Bosch 0280158040 injectors, I believe NZEFI sells them with some adapters to be a direct fit for RB25DET with top feed fuel rail.

Google will explain it better then me, but roughly, e85 has a lower energy content so more is needed compared to pump 98. Expect to use an additional 20% to 30% more fuel compared to pump 98. 

It is worth running, but you just need to size your fuel system appropriately for it.

The Injector Dynamic injectors have a horsepower range of 800-1200 HP, 1000-1400 HP. Should I go for something within my range?

Get the Bosch ones ...they will operate satisfactorily at low flows as well as at maximum.

      You're making my point for me. 95 is not "premium". It is a "slightly higher octane" version of the basic 91 product. The premium product that they want people to buy (for all the venal corporate reasons of making more profit, and all the possibly specious reasons of it being a "better" fuel with nicer additive packages) is the 98 octane stuff. 95 is the classic middle child. No-one wants it. No-one cares about it. It is just there, occupying a space in the product hierarchy.

      98 and 95 have to meet the same national fuel standards beside the actual RON.  91 has lower standards (which are quite poor really), so 95 is certainly not 91 with some octane booster. It would be an easier argument to claim 98 is just 95 with some octane boosters. Also RON doesn't specify 'quality' in any sense, only the octane number.  Anything different retailers decide or not decide to add to their 95 or 98 is arbitrary and not defined by the RON figure.

      95 is just a scam outright. 98 is the real "premium" with all the best detergents and other additive packages, and at least historically, used to be more dense also. 95 is just 91 bargain basement shit with a little extra octane rating. Of course, there's 91 and there's 91 also. I always (back in the 90s early 2000s) refused to put fuel in from supermarket related fuel chains on the basis that it was nasty half arsed shit imported from Indonesia. Nowadays, I suspect that there is little difference between the nasty half-arsed shit brought in by the "bargain" chains and the nasty half-arsed shit brought in by the big brands, given that most of it is coming from the same SEAsian refineries. Anyway - if there's still anything to that logic, then it would apply to 95 also. 98 is only made in decent refineries and, as I said, is usually the "premium" fuel, both in terms of octane rating and "use this because it's good for your engine because it's got the unicorn jizz in it!".
