You just had to bring the bolt cretins into this didnt ya, but i had already throught about them and got them covered.

Every one knows if you hang full cans of WD40 around the shed it sort of works like garlic and vampires. The garlic bit worked on the missus so i have high hopes on the bolt cretin cure.

forget fairies, find yourself some underpants gnomes. we all know they work all day, searching for underpants yay, they won't rest till they find underpants.... and so on. they are very hard working providing you can deal with them singing that song non-stop.

I have my engine sitting on the floor in the garage and it looks like the biggest pos that was ever made.

Just looking at all the bits n pieces all over the place makes me nervous to touch anything.

Day 15!

i was down to the last can of beer i had used in vain in my turbo fairy trap. The very last can, nothing else but the makers name and that was written in french and partly obsucured in blood from my torn up hands.

Thought i better wipe some of the blood away with an old rag before putting it out of its misery. And bugga me if the beer can genie didnt pop out offering me 3 wishes.

Wish one, please please put the turbos back on me car, poof .....all done!

Wish two, Return all the beer the barstard turbos fairies drank while demolishing my engine bay. Poof ...........full fridge!

Wish three, stock up the other fridge so i can at least temp the pressure plate pixies to come and replace my clutch as it aint gunna hold on too long with 455 AWHP after dyno session today.

WHOO HOO

yep all at .9 bar so i still have a bit to play with i would think just flat lined at about 7200 when wastgates opened. We did higher runs for what it was worth but we add some more fuel just to be safe and have AFR's mid 11's.

BIG improvement came from adjusting the cam timing was about 40 to 50 more HP depending on how hot the car was on its run. But just so much more agressive on ramp up really big difference mid range.

Gee I hope this is not part of the fairy tale - 455hp.

Nah - well done. Big effort. It almost makes the pain worth it.

Let's hope mine goes as well. :)

yer not to sure about the figure myself or how you calibrate a dyno dynamics 4 wheel dyno. but either way it performs sooo much better

But what a difference in performance...my hands dont hurt half as much as they did early last week.

I dont know about the figure produced but the tuner didnt seem interested in the graph reading much at all. didnt move his eyes from the wide band or remove the det cans from his head, really didnt give a rats about the figure.

Pay some-one else to do it...If your not a mechanic...

Cost approx...$500 to $600.Engine in..."don't make them take it out cause their lazy."

This will cost another $500

The extras such as new copper washers/bolts/gaskets/oil and water lines"if needed"

can cost though.

Great explanation / DIY Turbo replacement for a GTR..

Old thread i know. ...but..pretty sure removing the whole engine to do a more thorough job isnt being lazy, its called do it once and do it right

I will be removing my engine before I put myself thru this kind of pain and suffering, I know just from looking that there is going to be many tears

Very funny writeup.

This is the solution though. There's no way in hell I would attempt to pull all that mess down with the engine in the car!!!

To add fuel to the fire, I can remove my BW 8374 EFR completely in about 45 minutes. There are 4 nuts, 1 V-band clamp, 1 hose clamp, 1 vacuum/boost line, and 4 AN fittings to/from it. All very very accessible.

But in all honesty I did contemplate staying twin for a long time. But I DEFINITELY would convert to speed density (Haltech or other) by removing the MAF's remove ALL BOV piping spanning from the driver's side of the car over to the intake piping and change them for BOV's that don't open under part throttle, and just simplify the inlet / outlet piping in general. I think half the hassle is simply getting TO the turbos. I can't imagine trying to find a boost leak in that mess.

It can be done in the car and works without issue. How is it anymore thorough? Totally unnecessary to remove the engine!

    • The stock one will outperform any aftermarket standard position exhaust manifold. If you don't believe me, do a back to back test (same turbo, same boost, same timing) and you'll be super surprised.
    • Any recommendations on a decent replacement manifold that doesnt break the bank or require additional mods for the stock turbo setup? I figure if I'm going to pull the manifold off anyway to fix the studs might as well replace it. 
    • So I checked the turbo out today. Very minimum play at all just enough for the oil to take up when it's running. I did find an exhaust leak at the manifold. 1 stud all the way in the front is missing and the one all the way in the back is broken off. Front has visible signs of an exhaust leak. I'll fix that soon but that's not my problem still.  I also found that the nipple coming off the turbo had the hose capped off and a hose ran from the j-pipe by the bov going to the wastegate. I removed that hose and capped that nipple and put the turbo nipple hose back on the wastegate.  There was a ton of oil residue all through the charge side of the intercooler piping going to the throttle bodg. I'm thinking that's from the pcv. Doesn't seem to be coming from the turbo that was all clean on the pipes side.  Haven't had a chance to check fuel pressure yet, haven't had time been having to pull a lot of doubles at work. I did pick up some carb cleaner to clean the iacv but wanted to make sure I had a fresh gasket in case the old one rips when I pull it off.  I'm waiting on a MAF that was supposed to be here today but delayed to Monday. Have a double Monday and Friday and work all of next weekend so going to try to find some time in the middle of the week to try that out. Did about a 10m trip around the block today and towards the end the issues were coming back. Fingers crossed on this MAF but if not just going to throw a fuel pressure gauge in and see where I'm at.  Did notice today that I can definitely hear the injectors pulsing. Very audible clicking coming from them. Assuming that's normal? Should also mean CAS is functioning somewhat properly. After it warmed up when I started it the intermittent misfires came in again. Did start doing that before it was fully warmed up. 
    • This morning I carefully reinstalled the manifold and started looking at a couple of things I need to do.  Heat wrap arrived sometime today so I popped into the shed with the missus dishwashing gloves and started wrapping the first half of the dump and the screamer/plumb back.  Once I do the second half I'll be able to final fit the turbo and exhaust up.  Also pulled the harness out today and started terminating it at the ECU end. A connector is done, just need to run the remaining wires that arent in the harness - 12v, gnd and couple I/O
    • A31 is pretty much the same thing without HiAIDS I mean CAS, no improvement lol. Not to late to send it.
