R34 Gtt Hi-flow Front/dump Pipe Issues (with Pics)

Hi everyone,

Any help again much appreciated.

I'm going with the advice I received here recently and going down the high-flow route. Turbo came off the car tonight, please see pics.

Current spec:

R34 GT-T manual

Intake - K&N-style pod thing

Turbo - stock, getting high-flowed next day or so (keeping stock housings)

Dump pipe - looks stock

Front pipe - Nismo "20020-RNR40" with a narrower section at the start

Cat - ?stock

Cat-back - 3" Blitz Nur Spec

Everything else - stock.

So as you can see my problem is still having a stock dump pipe and a narrower section at the top end of my front pipe (is this an issue?). :P

Question is, what are my options? Obviously need to go for a larger dump pipe and work my way around the front pipe issue if I have to as well.

I've searched the stickys at the top of the forum and the only suggestion seemed to be a custom option.

Any specific brands/models, or is custom the way to go? Plus, anyone in Brisbane (preferably Southside) who knows what they're talking about and you'd trust to be able to supply me with said bits this week?

Sorry for all the questions but if I can go in armed with knowledge from here plus what my mechanic tells me then I feel much better about the situation.

Any comments much appreciated! :(

Cheers!

I use a CES split dump they are in qld I think www.cesracing.com.au or something like that.

was good for stock turbo and now for GCG highflow.

with new turbo you need bigger fuel pump, new fuel regulator, best to get new injectors. 480cc nismo drop in easy. and a PFC to tune it all up. some say you need a z32 AFM some don't.

      My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.

      Which solenoid? Why was it changed? Again, why was this done? ...well, these wear..but ultimately, why was it changed? Did you reset the idle voltage level after fitment? I'm just a tad confused ~ the flash code doesn't allude to these items being faulty, so in my mind the only reason to change these things, would be some drive-ability issue....and if that's the case, what was the problem? Those questions aside, check if the dropping resistor is OK ...should be 11~14 ohms (TCU doesn't throw a flash code for this) ~ also, these TCU designs have full time power (to keep fault code RAM alive), and I think that'll throw a logic code (as opposed to the 10 hardware codes), if that power is missing (or the ram has gone bad in the TCU, which you can check..but that's another story here perhaps).

      Question for people who "know stuff" I am looking at doing the new intake like the one in the picture (the pictured is designed for the OEM TB and intake plenum), this design has the filter behind the front bar, but, the filter sits where the OEM duct heads into the front bar, and the standard aperture when the OEM ducting is removed allows the filter to pulled back out of the front bar into the engine bay for servicing, a simple blanking plate is used to seal the aperture behind the filter This will require a 45° silicone hose from the TB, like the alloy pipe that is currently there, to another 45° silicone hose to get a straight run to the aperture in the front bar Question: how will it effect the tune if I move the MAF about 100-150mm forward, the red is around where my MAF is currently, and the green would be where it would end up Like this This is the hole the filter goes through  Ends up like this LOL..Cheers

      Despite the level up question, actually I do know what that is....it is a pressure sender wire.  So check out around the oil filter for an oil pressure sender, or maybe fuel pressure near the filter or on the engine. Possibly but less likely coolant pressure sensor because they tend to be combined temp/pressure senders if you have one. Could also be brake pressure (in a brake line somewhere pre ABS) but maybe I'm the only one that has that on a skyline.
