New 26 Just Dropped In

[Crans]

Just dropped in a 68k Rb26 with HKS 2510 turbos into my 32 gtr. She started up really easy idled really really rough and blew alot of white smoke. This finally cleared so i guess it was just oil from the engine sitting around for a long time.

Heres the current problem. It is really really slow to free rev takes ages to get to even 4k. Stabbing the throttle does stuff all compaired to my old rb20.

Taking it for a test drive tomorrow to see how it goes.

Now I know there is one problem the CAS was loose. We have set the timing to where it idles the best and tightened it up. Want to get a timing light on it but cant see how with the coil plugs.

Any ideas on setting timing and the possable problem?

you can still use a timing light to find the base timing id say its either CAS or maybe the timing belt now put on properly possible skipped tooth?

Where do you hook the timing light up too? i doubt its skipped a tooth on the timing as belt is well tensioned and was not removed being a 68k engine it should be due for replacement yet.

Taking ages to spin up is probably due to timing too retarded, so that maximum combustion pressure occurs after TDC. Using a timing light on RB-series engines has been covered numerous times.

Did you get the injectors cleaned before you installed the engine.

[Crans]

Retarded timing was my first guess. Running some injector cleaner through it with the fuel. Being a 68k engine i didnt think a full clean would be needed.

Ill do a search for setting timing

... Running some injector cleaner through it with the fuel. ...

Pretty much a waste of time, if the injectors are already dirty. And if the engine has been sitting around for a while, who knows what condition they are in?

[Bliksem]

Injectors can varnish up, happened to me when buying some second hand ones. The only fix was a proper clean at a specialist. From memory the timing light works on the white wire on the coil pack loom.

[Crans]

Hmm ok ill rip them out and get them cleaned aswell

Run a HT (conventional coil lead) lead between the coil pack and spark plug and clip the timing light on that.

[Crans]

Gonna give the lead a go tomorrow hopefully works and fixes up everything

[Crans]

Timing gun attached and working. Just need to be 100% sure about setting the timing.

Idle at 950rppm timing should be set to 20deg BTDC

From left to right what does each mark represent? I think i have it done right but just want to make sure.

Have searched through the gtr service manual but at 300 pages i haven't found anything yet.

Cheers for the help

Details are shown on page EN-11 of the genuine service manual......28 pages in from the start of the manual (well, it is in my electronic version)

[Crans]

Don't know how I missed that part. OK Timing set now. Issue with coil pack fixed and she now seams to be running alot better.

Al tho its now blowing a heap of white smoke when i give it a bit of throttle. Smells like oil burning. Could it be oil in the cooler pipes from the old engine?

[TwentySix]

LOL !

[ali-turko]

dosnt sound to promising, white smoke is not a good sign

[GTScotT]

comp test before u go any further at least

[Adriano]

Just because it has 68k, dont assume anything, my gtr had 53000 genuine km, and 2 cracked pistons

[Crans]

May as well update this even tho car is gone.

White smoke was from a massive build up of oil in the cooler pipes from the old engine.

Engine problem was due to dodgy silicon joiner that would only open up under boost. Car ran perfect after this.

LOL !

what is with people diging up old threads for no reason but to put LOL or something stupid in them.
