Is It Safe To Drive The Car Hard

Hi everyone,

I have just put a set of Garrett -7s on the 34 GTR, with HKS boost controller to 1 bar, stock injector/fuel pump/fuel rail, with full WELDINA NE-1 exhaust.

Before doing that the injector is about to maxing out about 1 bar on stock turbo.

My question are:

* Is it safe to drive the car hard for the current mod? (new mod's on the way)

* What is the consequence of maxing out the injectors with a bigger turbo? is it going to damage the engine in any way?

* What happens if I increased the boost to 1.2 bar with stock injectors?

The car is not even on road yet so all these questions are hypothetical. however I would really appreciate if I get some answers.

Thanks.

Maxing out the injectors means that they cannot flow or add any more fuel to compensate for the increased air flow when u turn up the boost so the engine will lean out and guess what.....BANG!!!!

Turn down the boost to 10-11 psi and u "should" be good until an injector AND ecu upgrade

Thanks!

Got pfc. 550cc injectors are on the way. are they big enough for -7?

Also wondering which is more harmful to the engine: too much air or too much fuel?

"Give me your R34 GTR, you don't deserve it." :/

Seriously...

550cc will be good enough for pump...if u have plans to go E85 u might need to go bigger

Too much air with not enough fuel....as in your case

lol we all stay up a bit late...

Bosch 044 + 550cc will be the fuel set up.

E85, is it road legal? i'm not sure just asking...

      Exhaust silencers/varex exhausts

      By PotatoCake · Posted

      Yeh... literally every time i jump on a forum, see an instagram post or see an engine bay at a car show, i get an idea and add it to my 'to do' list. So what started off as, hey can u just make a couple of intake hard pipes because my dumbass bought the wrong apexi kit, blew out into a 2 week job including braided brake lines & custom bash kit for the front lip haha.  Getting Luke from A4E engineering to make a full custom exhaust with a controllable aes dump valve so i can actually switch between quiet and loud, because right now its just loud all day every day. Then after that go and get the tune redone flex e85 & 98 as i get bugger all milage from e85, makes going for longer drivers difficult

      Car looks clean as. You ended up getting quite a bit done 😂  So what's the plan for the exhaust?

      Rb25det vs Rb25de rods and crank are same?

      By GTSBoy · Posted

      The only Neo rods that were any different to any other RB25 rods were the DET ones, and they were the same as RB26. Here is a Neo DET rod. O5U part number visible. Here is a post in a thread here on SAU with evidence from someone who has done this before. There are photos in the thread of normal RB25 rods.

      Magnetic Drain Plug Snapped in Half

      By joshuaho96 · Posted

      Sure, but why assume that will be the case forever? And why assume you'll be able to do an oil change to swap back to a stock drain bolt before that happens? And does it even matter when I change the oil at fairly short intervals? Life can be funny sometimes and unexpected things can happen. Like breaking a collarbone so you can't do any work on your car for a few months but the oil change is due so you have to take it to somewhere and hope they don't do something stupid like stacking the new drain plug washer on top of the old one.

      Do u know how to identify the rods are rb25 or neo ones? Can u look into the pics and tell me is they de or de neo ones. Its confusing becoz my motor has de neo head but block is 25de 75t, so really confusing me about rods, crank.
