Gday guys,

 

I’ve posted this in other places online but no one has given me an answer to this question **(edit- also did a search regarding HICAS delete/HICAS solenoid here on SAU too and couldn’t find anything after a good look so apologies in adavance if it’s asked a million times and I missed it)**, is the HICAS solenoid required on a 32GTR after HICAS itself is deleted?  Just wanting to know since I’m in the middle of an underbody and subframe refresh.
 

The car already had a HICAS delete before I bought it and the two hardlines that go from the solenoid to the engine bay/power steering system were already completely disconnected and just sitting there open to the elements and unattached to anything, it’s just that the solenoid itself still had the brown electrical connector attached to it at the rear end of the car.  Happy to tuck it away in the back of the shed with everything else not needed that I’ve pulled off the car but if it’s still needed to be electrically connected to make a circuit to do something in the car I guess I’ll have to bolt it back in.  The car will be running a full aftermarket ECU and dash set up if that’ll help me to understand if it can come out so it could possibly be tuned around or have no warning lights on the dash. 
 

cheers guys, have a good one!

No wonder the engine bay solenoids were missing, someone probably wanted to change the oil filter at some stage.

Was there any flexible lines connected to that solenoid where the banjos are?

Legend, happy days. Already on my way to chuck it in the pile of crap I’ve taken off so far.

Negative.  The only thing holding the rear solenoid and two hardline pipes on was a couple of bolts holding the solenoid to the chassis and the brackets that ran up with the fuel inlet/outlet/breather hoses and rear brake line.  No flexible hoses attached to the solenoid at all, it has literally been doing nothing as far as I could see, was just worried the car would still need to have the circuit connected.

    • It would be well worth deciding where you want to go and what you care about. Reliability of everything in a 34 drops MASSIVELY above the 300kw mark. Keeping everything going great at beyond that value will cost ten times the $. Clutches become shit, gearboxes (and engines/bottom ends) become consumable, traction becomes crap. The good news is looking legalish/actually being legal is slighly under the 300kw mark. I would make the assumption you want to ditch the stock plenum too and want to go a front facing unit of some description due to the cross flow. Do the bends on a return flow hurt? Not really. A couple of bends do make a difference but not nearly as much in a forced induction situation. Add 1psi of boost to overcome it. Nobody has ever gone and done a track session monitoring IAT then done a different session on a different intercooler and monitored IAT to see the difference here. All of the benefits here are likely in the "My engine is a forged consumable that I drive once a year because it needs a rebuild every year which takes 9 months of the year to complete" territory. It would be well worth deciding where you want to go and what you care about with this car.
    • By "reverse flow", do you mean "return flow"? Being the IC having a return pipe back behind the bumper reo, or similar? If so... I am currently making ~250 rwkW on a Neo at ~17-18 psi. With a return flow. There's nothing to indicate that it is costing me a lot of power at this level, and I would be surprised if I could not push it harder. True, I have not measured pressure drop across it or IAT changes, but the car does not seem upset about it in any way. I won't be bothering to look into it unless it starts giving trouble or doesn't respond to boost increases when I next put it on the dyno. FWIW, it was tuned with the boost controller off, so achieving ~15-16 psi on the wastegate spring alone, and it is noticeably quicker with the boost controller on and yielding a couple of extra pounds. Hence why I think it is doing OK. So, no, I would not arbitrarily say that return flows are restrictive. Yes, they are certainly restrictive if you're aiming for higher power levels. But I also think that the happy place for a street car is <300 rwkW anyway, so I'm not going to be aiming for power levels that would require me to change the inlet pipework. My car looks very stock, even though everything is different. The turbo and inlet pipes all look stock and run in the stock locations, The airbox looks stock (apart from the inlet being opened up). The turbo looks stock, because it's in the stock location, is the stock housings and can't really be seen anyway. It makes enough power to be good to drive, but won't raise eyebrows if I ever f**k up enough for the cops to lift the bonnet.
    • There is a guy who said he can weld me piping without having to cut chassis, maybe I do that ? Or do I just go reverse flow but isn’t reverse flow very limited once again? 
    • I haven’t yet cut the chassis, maybe I switch to a reverse flow. I’ve got the Intercooler mounted as I already had it but not cut yet. Might have to speak to an engineer
