Hi guys

Just wondering how good the R34 GTR fuel pumps are as i am about to fit 750cc injectors and power fc (keeping standard turbo's for now) and have been told the GTR factory pump will be more than sufficient for this (by an actual tuning shop who you would think would try talk you into fitting a new one for they're benefit)and are good fuel pumps to over 300kw which i wont be getting near with these mods. It would save me fitting an aftermarket pump till i'm ready to upgrade turbo's AFM's etc. Can anyone else vouch for this or has experienced the GTR pumps limits/performance?

Thanks

I have to ask... Why you are putting in 750cc injectors with stock turbos???

Stock injectors will flow more than stock turbos can make. So sticking with stock injectors would be a far smarter idea, and keep your 750cc items for when you actually need them.

A GTR pump can flow 380rwkw no problem, been done before by two people i know.

Infact there is conjecture as to whether or not the Nismo pump & OEM GTR pump are actually the same part - as there is evidence to suggest they might well be. Wouldn't be the first time Nissan have branded the same part with a different part number and price.

The only thing sticking point, the "OEM" GTR one costs much more than a Nismo replacement, so it makes sense that people just buy a Nismo item.

***HOWEVER*** the pump you have now, is 10 years old or there abouts. I think for a $300 part, it's simply a risk not worth taking. I'd be swapping it out with a Nismo or a Bosch pump. Nismo being easier to install and a bit more expensive. I would honestly change it for piece of mind.

    • The brakes are all stock bar some DBA slotted discs and the EBC pads and braided lines. The car has brake ducts as standard but they're kinda pointed in the general direction of the brakes rather than really getting at the heat source. I guess I should hit it with an infra red thermometer after a session and see what they're at.  100%! Its just a curiosity more than anything. As I said, high temp brake fluid was such a track day rage back in the day. From people I speak to at the track and threads on here everybody has their own take on it but I'm not gonna scoff at spending a few more bucks. 
    • I've always approached this as, price is comparable between low temp and high temp fluid. Just put in the high temp fluid. I've not going to lose any sleep thinking about could I have saved $20 on brake fluid that is going to live in the car over the next 2 to 3 years. 
    • Nah, the creases were pretty large, and the sheet metal is pretty thin and hard to work out, time alone is in the hours to fix, and would probably have more bog than I would be happy with In other, more happy news, I gave MX5 Mania a call and they have a few clean boots available for $400 a peice, I've contacted Fineline and given them their contact details, I'm a idiot for not thinking of them sooner
    • That really depends on how hot the brakes get and how much of any heat is transferred into the fluid. That really makes it at least a vehicle specific question, and more than like a specific vehicle specific question, depending on what brakes (ie stock, bigger rotors, different calipers) or even what pads are on it. And then there's the question of cooling air. Is there plenty stock? Is there no special cooling arrangements stock? Has some/more been added? In other words, I think you have to do the experiment to obtain the data. And if you;re worried - tie on some ducting?
    • In all the track days I've done over the past few months I've only had 1 issue with braking and thats with my current EBC pads (can't remember the colour, but they're not a track pad). I don't *think* I have had issues with brake fluid getting too hot, my understanding is that when that happens you will have quite noticeable brake loss - which I haven't had.  I'm using just regular ol' Penrite Super DOT4 fluid. I use this fluid in everything and my cars always seem to stop so I see no reason to change, except ... for the 335i. I need to do a fluid flush and was thinking about my fluid of choice and wondering if I should consider using something more high temp? Its not a super fast car by any standards but I'd hate to do a flush and then find myself with no brakes when I get. to Wakefield.  I guess, my question can be summed up as "How fast do you need to be driving to need higher temp brake fluid?"  I remember high temp fluid was considered a must have back in the day when I had my GTR.
