Work Log: R33 GT-R

[speedracer1610]

I have a similar engine build my car made 591hp to the wheels. Nice work.

[NismoS-tune]

Mr Purplestreak, I believe we have met. Let me know if I'm correct...

Some random GTiR guy you may have run into
Anyway, let me know if you need help as I'm sometimes in town for work, I know a thing or 2 about GTRs.

As for your parts, have you bought those yet? If not here's my opinion if it matters:

-Forget the Cometic head gasket. Go Tomei or HKS.
-As for spark plugs, forget Iridium, if they ever foul, they are most likely scrap, plain Race coppers work fine and I run really rich without issues all the way to 9500rpm and I also use high voltage ignition coils so they're tough. They're cheap and can be ordered at NAPA, I'll get you the part number.
-Turbos, -5s are great but at 450whp, you're better off with SS or -7s as they spool faster and have been known to be able to go over 500whp where the -5s are laggier but good for more power. If you don't have those yet, I have a set available, they have less 2000km, ceramic coated (kickass) and are ported to improve flow. PM
- If your engine is showing low numbers on 5 and 6, I would be careful on making more power. It can make things fail easier and could cause more damage when boosting more. If you do find a tuner that will get you that power, don't tell him about the comp test. I had 165 across the board and a clean car but the tuner stopped at 300whp on -5 which means a stock GTR was faster lol.

2 cents.

Thanks, my goals aren't quite as lofty, but the setup should certainly be capable of that after an engine rebuild..

[PurpleStreak]

Of course I have met you and your GTiR!
Your advice was definetely heeded..

- I'm just getting assorted gaskets for the header and turbo, going no where near the head gasket yet!
- Marwan told me the same thing about the copper plugs, now I feel kinda stupid for paying $130 for spark plugs lol. BKR7Es, correct?
-I already have the -5s...At the time I was looking there were no -7s available, and I was split between the -5s and N1s..I decided to go for the -5s just because they offer more potential and I don't have to improve flow everywhere else to improve their efficiency over 500hp..I just want to use them as a stepping stone after a built bottom end and before a larger single.
-That's pretty much why I set my sights low..I'm kinda prepared in the back of my mind to do a rebuild in case things do take a turn for the worse lol...but at any rate I would like more power albeit with a safe tune. I'll do my best to convince them to not stop at 300whp lol..

Thanks for the input!

My lack of updates can be attributed to 3 weeks in China and 2 weeks of a wicked sinus infection! I've been holding off on removing the turbos till I manage to fit up the downpipe. But of course, the eBay downpipe doesn't fit..



Hopefully one of the two downpipes I bought will fit. Once I decide which one to go with, I can get the bung installed and get those stock twins out!

In other news, I got something I've been looking for a very long time from a good guy in Australia, a Pivot turbo timer!



It's not as flexible as my current TT, but it looks much better with it replacing the coin slot! ( as pictured below, ignore the damage on it)

[PurpleStreak]

Finally got some progress..I don't know how some of you swap turbos in a day, but gettign the stockers off is a royal PITA!!

I removed some of the ancilliaries from the -5s to attempt to fit the new coolant and oil lines. Removing this 'manifold' means limited access during installation and future removal; but the advantage is it eliminates some of the bulk of the assembly. The 'manifold' can be removed via the bolts onto the compressor housing and the oil and coolant banjo bolts:




The coolant return fitting threads out of the housing:



Test fit of the new fittings is a success. It won't be possible to install these at either end when the turbos are in place, but should be doable when the turbos are placed in the engine bay prior to bolting up the manifolds.




The oil drain on the rear turbo has to be changed to the new Nismo fitting for the separator, however this needs to be modified as the oil drain flanges are smaller on the -5s than the stockers.



As for the removal of the stockers, I had removed all the inlet piping last year.



I simply broke the coolant return tubes because they were in the way and it was not possible to get them off. Besides this, the oil and coolant supply lines, turbo supports, brackets, and oil drain line came off with relative ease. Overall, the front turbo and manifold came out with relatively less trouble..



The rear turbo was more of a story, due to the limited access to one of the manifold-turbine flange bolts provided by the firewall. The manifold and turbo had to come out in one piece. Access to the manifold was much better this time around though.



Of course, during all this time, because I didnt bother trying to get to the poorly located coolant drain plug on the block, I dealt with periodic coolant showers. I would like to install a little drain line off this fitting to faciliate easier coolant changes in the future.



Next up is:
-replacing manifold studs ( I damaged some of these during the struggle with the front manifold )
-match outlet port of manifold to turbine inlet port
-paint manifold with VHT Flame Proof ( since the heat shield bolts broke off lol)
-transfer all turbo ancilliaries from stockers to -5s

Nice car man love the color. It really suits the 33. What site do you work on? I'm at albian

Thanks! I work at Suncor Base Plant..are you in camp or local?

EDIT: Ah the grove, nvm

[Robin026]

The perfect color for a 33GTR, good luck with the car and updates.

Nice car! I wonder who owns the other R33 GTR Midnight purple that was sitting at Fraser Wharves last month. It had a CF hood and Sparco hood pins.. RHD maybe?

if it had 3 spoke rims chances are that was mine
