its a r34 gtt with a r33 gtr head and 3L bottomend.

i left a message on your ans machine and sent a msg to your mobile about my specs trent but here is is again.

rb26/30

gt35r .82

18psi

standard oem cams

standard valve springs

intake port matched and polished to runners

3.5" dump

3.5" straight pipe exhaust

5" cannon

cp pistons

spool rods

9:1 comp

cosmetic head gasket

china brand fmic with 3" intake side pipe 2.5 exhaust side pipe (my guess as to the problem but no proof or expertise to back it up)

Nismo Twinplate Coppermix clutch

splitfire coils

340rwkw

to be honest trent ive called a few shops and like the forums everyone seems to have different opinions as to why it wont make more then 340rwkw regardless of how much boost i dial in.

psi drop on cooler

head flow

valve springs

cams

rather then spending money on things i dont need i would like to get the car tested and what ever it needs, i can replace.

1st post - you wanna just start porting/polishing

By the 4th post you want to actually check whats going wrong... AMEN.

After 12 months of us all (in FI section) telling you to get the current setup checked by a knowlegeable professional, it seems you are finally coming around!

Stop with the "I want to change stuff" and start with the "I need to FIX my current setup first".

We've been telling you for ages to get the cooler pressure drop & valve springs checked... :D

No offence with the above, I'm just totally at a loss as to why you've still not done anything that anyone has recommended for over a year

Trent - before looking much more into it, go over this guys past thread history and have a read of what people have tried to help with so far.

15mins reading will save you hours of rechecking :)

ash i just wanted to talk to someone about my porting and polishing options and wether or not i do really need it. i dont think you can fault me for trying to find out what i should do from a expert. but your right i have taken my time in seeking help but its not easy for us uni students. money isnt that free. although i do want to say sometimes to fix things i do need to change things.

moving forward though as i said id just like to talk to a professional on what the next step should be. Because really if i dont need springs why should i buy them. so i have officialy taken your advice and am seeking out experts to get my setup checked.

ive contacted Rob @ sab automotive, and i wouldnt mind getting trents throughts on things to.

cheers

hmm i will listen to message when i get to work in the morn and check all the threads for things that have been covered. (was offsite all day today, out west actually)

being a 26 head it should be fairly straight forward. Just quickly whats the exhaust cam wheel set too?

im not sure that was ever changed trent as its still running the standard oem rb26 cams.

Put a better quality intercooler in. Drop in some poncams. 360+ kw :D

the problem is that people people have made close to 400kw on standard cams. so really if its possible i dont want to waste my money on cams and lose out on bottom end torque, which is really where i want it all to be.

most likely ill need a 100mm intercooler.

With a 3ltr it will take a bit of cam compared to a 2.6, either way it is NOT the cause of your problems currently.

Depends on what work gets done to the head etc as to what specifically you put in there.

Yes you can play the uni card dude, but you don't build a 400rwkw setup working 4hrs flipping burgers @ maccers :P

You don't need to change anything ATM to fix whatever issues you have, simply because you don't yet know what is wrong.

    • I know you don't want to hear this comment, but I can't not say it.  I just can't see 200kw being worth the time and effort. Its like guys with NA cars, putting in headers/exhaust/tune for a massive 20% jump in power. Great, the slow car is still slow and you're down $10,000.  My vote is leave it NA or price in a gearbox upgrade and shoot for at least 300KW, preferably 350KW+.  Now you have a NC that will try to kill you from time to time and will be exciting to drive
    • Ah yep. The main message I want to pass on is, try not to get scared of ghosts when thinking about knock/knock detection.  What I mean is, healthy engines make noise. Knock is also noise. Your knock sensor and ECU combo are trying to determine bad noise from good noise based on how loud the noise is. The factory knock sensors and ECU are not good at doing this.  Modern ECU's are pretty decent at it, however I'd still say that you would want to verify that if your ECU says it's knock, that you actually listen to it and confirm that it is correct.  Are you familiar with the plex knock monitor?  https://www.plex-tuning.com/products/plex-knock-monitor-v3/ I expect you're the type of person that would be very keen to play with something like this. It is great knock detection and you can pop some headphones on and listen to what's going on.  Knock that you've deliberately induced in low load low RPM areas is not really putting anything at risk and is a great tuning/learning/verification tool.  I just thought this was worth mentioning based on the way you were talking about setting up a base map and the Haltech base map settings. There are better ways to spend your time then chasing ghosts and worrying about detonation in scenarios that it is crazy unlikely to encounter it.  I was also wondering, what ECU are you planning to get? Will it be long til you pick it up?
    • This came quicker than I thought. It ain't even 2025 yet.
    • I somehow quoted my post instead of editing it. I regret nothing.
    • STOP GOOGLING FAB9 MAKE BORG WARNER EFR KITS FOR THE NC. THEY PACKAGE AN EFR 6758. DO NOTHING ELSE. CAPS INTENTIONAL. THE BEST RESPONSIVE SETUP EXISTS FOR YOUR CAR, AND HAS BEEN PROVEN FOR QUITE SOME TIME NOW. IN B4 "BUT I WANT EVEN MORE RESPONSE, IN A SIMPLER, MORE RELIABLE PACKAGE" WHICH IS A LS.
