Engine out. That looks serious! Hopefully serious upgrades not seriously broken.

After my upgrades, I am sitting at 360 awkw @ 20psi. I did a subset of the original plan. The main thing is just how much nicer the car is to drive with modern injectors, better ignition and e85.

All preventative thankfully...

-head gasket

-head studs

-oil pump gears

-general inspection

-and engine bay respray

 

what turbos you go to make 360 @ 20psi?

That sounds like some good items to tick off before more go faster bits.

Still using -9s but 2psi more plus e85 etc.

good results, definitely could pump a few more psi in there now you're running E85 if you wanted.....

25 psi if you have head studs, head gasket etc shouldn't be too much of an ask.....

That's a lot of power for -9's, especially only at 20psi.  What other mods do you have?

Performance stuff:
Plazmaman intercooler (the smaller one not 100mm)
1000cc injectors
Walbro 460
AC Delco coils

Other stuff that may be relevant but probably marginal benefit:
Built engine
Trust front pipes
Apexi exhaust
Apexi pods

Are you still running factory intake piping?

I got this divided charge pipe made not too long ago, if you are unsure about buying a whole intake piping kit.

Are you running any cams?  

I'm still running factory air box, so maybe that's my problem.  Or maybe because I'm running R35 injectors at factory fuel pressure.  I read somewhere that R35 base fuel pressure is 1 bar higher and that's why it can get that much power out of 570cc.  Not sure if that's true.

Just to clarify, the power output is based on e85 and not 98.

My cams are factory.

I recall reading that the air box is good for 400kw. I just felt like hearing some more whoosh.

As for the injectors, mine were rubbish and needed to be replaced regardless of any power goals. I thought that you needed a higher cc rating than 570 to support e85 (on an RB26).

ye 570cc injectors will get you nowhere near 400....

Mine should be fairly close to your modification list once finished @Robzilla32, only I'm keeping factory airbox but i'll be running some mild cams and slightly larger turbos...

My goal is 350kw without e85, that's why I thought the 570cc would get the job done.  I rarely drive mine and a full tank would last 2-3 months, so I can't really run e85.  I also thought running R35 injectors with R35 AFMs should be a friendly combo to Nistune. 

Getting closer at 315kw during my last pull.  Bought a 76mm Plazmaman but yet to install it, still waiting for my tuner's dyno to be repaired...

      I can believe it if you're getting air into the pickup. Cavitation is tremendously destructive for pumps.

      I think the pic in the first post is another car, and post 7 is OP's car with standard arms and swaybar swaybar swaybar. I can't tell what brand the silver coilovers are, and even if I could I don't know whether the spring rate is OK, if you can find a brand on the shocks and numbers on the springs that might help. Also, if you can measure the ride height from centre of your wheel to the guard that will help with advice too as handling suffers if ride height is too low

      In the first photo you posted, the colour of the control arms are the signature colour for Ikeya. Same for the swaybar, signature colour for Whiteline.  I like Hardrace, they also do hardened rubber bushes if your car is mainly a street car.  I like GKTech as well, but they use a lot of rose joints in their stuff so might not be the best choice for everyone.  The system might have been good back in its day, but it's a prehistoric system now. I suspect that most people have removed the HICAS as they want the car to do what they want to do, not what the car wants to do. From what I also understand, it isn't consistent in it's behaviour on track so it's hard to trust the car/know where its absolute limits are for track use.  Having said that, I think the HICAS eliminator kit was the first thing I installed when I bought my car. I don't personally have any experience with the HICAS system on a race track.

      Thanks for the info. Didn’t know I had aftermarket control arms already? Will talk to my garage. What brand would u recommend if I want to play around with my camber more? I would think my camber is around stock level right now or more negative now due to lowering with coilovers. I will be lower her again 1.5 cm to get some more.    also why does everyone like to remove the hicas system? Is it because most don’t work properly anymore or ppl just don’t like them. Mine is functioning as it should be right now.    thanks for the good info
