OK people the engine is finally in!

The fuel rail,fuel lines,injectors,coils,pumps,power steering and lines are all done.

All of the harnesses,plugs and connections are done also.

Just have to do the vacuum lines and move a few things about. Aswell as the gearbox and tailshaft.

Had the engine in and out 3 times as the external oil drain gave a bit of grief clearance wise. A small patch of the firewall was "massaged" back an inch and then painted. Turned out really good in the end.

Pics will be up next week :domokun:

EDIT: BRIDE seat is in too.Man that thing is snug :O

NICE! Been keeping a real eye on this thread, will help me decide on whether to keep the GT30R/RB25 combination :P How hard are you going to push the tune when you do it? It'd be rude not to crack the 20psi mark!

14psi for the run in tune,and 20-22psi for the full tune.

22psi is alot of boost to run on pump fuel. See how the motor likes it on the day,though i would like to see how much i can squeeze out of the turbo before we settle on a good reliable tune/boost setting.

Ahh yeah sounds like a good idea, on both levels :) 22psi is pretty much where I'd be going high boost as well. 20-22psi is high but really a safe limit for pump gas, so long as you have a good tuner etc - I know people running way more than that, but they are certifiable.

Really looking forward to seeing the results on 20-22psi, it should go very very well.

29psi with a GT30R?

DOH I was a bit slow on editing it, I was just talking about boost level in general. No, not on a GT30R - there's probably no point going over 22psi on your setup... sounds like just the right level :)

Well after 2 days of trying to get the gearbox on,its finally on.

But i had to remove all of my hard work and pull the motor out again!!! :D

For some silly reason the input shaft wasnt going in properly.The splines would align but stop about 10mm of being flush with the block.

So the decision was made to pull the motor out....again....for the 4th time.

Off the car the input shaft wasnt going in properly, so i removed the clutch,had alook then tried to align the clutch plate as straight as i could.

Clutch back on still didnt line up. As i was about to give up i just gave it one more half assed attempt and donk! Slid straight in.

Which kind of pissed me off because i didnt do anything different to what i had been doing for the past 11ty billion hours.

So then the box and engine went in together,which was very stressful.

But anyway the engine and trans are in,with all the ancillaries. Tail shaft will go on tomorrow.

So a week or two from now ill be getting all the piping done and she'll be ready for a drink of oil and the install of the Haltech.

Then fired up :banana:

should instal the haltech wiring now while your loom is out, i got a LTX12 that im installing before i put the motor in, however im also getting the engine tuned and run in before it gets into the car lol.

acually, when you put the engine back in with the gearbox attached, did you have any clearence issues with the oil return 90degree bend comming from the back of the head?? just thought about it since you have to have more of a angle to get the box in... unless you got a high engine crane and jack the car up a bit.

Safe boost pressures come down to if your within your turbo's efficency range, and if your tuner can tune the car accordingly. Highest boosts ive seen and experienced on 98 octane was was 30lb on a 2jz making a little over 500rwhp (GT35R), and a RB3025 with 32lb making 625rwhp(custom T51 varient). 4th gear traction loss at 180K's, yes.

If your engine has the forged pistons and rods to support at least 100hp per cylinder whats holding you back...

Im buying a flying lead for the Haltech so its plug and play.The oil drain was a bit an issue but we managed in the end.

We will see how it goes when the engine is run in,i wouldnt like to boost it over 22 psi as my comp ratio is slightly higher than standard.

The GT3076R when I looked for and chose one looked like it'd be best used at around 22psi on a built RB25DET so there isn't a huge amount of use for it over that. Its a nice not overly laggy turbo on an RB25 so with 22psi there should be a huge fat power delivery, it'll be wicked for a road car that can do drag and track. Just because the engine CAN make 100hp/cyl doesn't mean you are obliged to - it just adds one part of the equation to get what you want out of it.

Highest power pump gas/power per litre car I've been in was a still 2litre EVO 2 running a .82a/r GT3582R running ~2bar of boost putting down just under 500whp (125whp/cyl), way faster than any daily driveable 4cyl street car should be.

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
