R33 RB26dett into R32 GTR

[BOoStEr]

I need to know if this is a straight swap.

If I need to change the ecu is the loom the same?

Is there any thing else to be considered?

[BOoStEr]

The original engine died due to oil-pump failure. Is this an unusual occurrence? Any idea what might have caused it as the history of the vehicle is unknown?

[blind_elk]

Don't see why it shouldn't be a straight "unplug dead engine, plug in new engine".

The oil pump seems to be one of the few short-comings of the Nissan RB-series engines. I'm led to believe that the securing bolts tend to work loose (from heat / cool cylcing), then oil can be pumped out the gap, so not all the oil lubricates the engine.

[BOoStEr]

The failure in this case seems to be due to the drive gear cracking in the corner of the flats.

Yep this is exactly what happened to my mates rb20. The securing bolts worked loose , had no oil pressure, engine died.

[BOoStEr]

Has anyone heard of a problem with these gears splitting?

Is the oil-pump drive different in the R33 motor ?

[Skyrine-Dave]

can i have your dead rb26 for free?

[BOoStEr]

ROFL, not mine to give.

[ph1]

yep, a common problem in the r32 rb26, the oil pump drive is longer on the r33/r34 crank to rectify it.

[BOoStEr]

Thanks ph1.

So, anymore on whether this is a straight swap?

[Guest tigersharkr33]

it is straight swap,but you have to rebrogram the old ecu.

[BOoStEr]

Thanks tigershark, What's different about the motors that it needs remapping? Could I use the R33 ecu or is the loom different?

[Guest tigersharkr33]

there is no diffrence,i meant that you have to reloom it,the engine is the same,but the ecu and the loom is diffrent.because it is newer version.if you check with apexi power fc you will see that the part for the r32 is diffrent with the part of the r33 as well the r34,but everything can be done,check with mick at http://www.tilbrook.com.au/

he will help you.

[BOoStEr]

O.K., so they changed the loom and ecu between the R32 and R33 but if the motors are identical wouldn't a R32 ecu and loom run a R33 motor as well as it runs a R32 motor?

[Guest tigersharkr33]

it will do the jop.

[Mr R32 M-Spec]

is that something you should check regularly. can I tighten the securing bolts myself? where is it located

[JimX]

How long does it take with no oil pressure to kill the engine? I'm going to keep a closer eye on my gauge now, and check the pump bolts in my upcoming service. Just as soon as someone tells me where the oil pump is

Hi JimX you asked .......

"Just as soon as someone tells me where the oil pump is"

Front of the crankshaft behind the harmonic balancer, lower cambelt cover, cambelt, and cambelt pulley. The oil pump bolts to the block and the front part of the sump bolts to the oil pump. The radiator has to come out before you can get to all this stuff, plus the belts, covers and pulleys.

I reckon it would take you a full day to remove everything, check the bolt tension and put it all back.

Lesson, tighten the bolts properly and use locktite. Do it right, do it once.

Hope that helps.

Ye gods, I think I'll just wait for it to work itself loose. Are there any warning signs that your oil pump is falling out?

How long after the oil pressure light comes on does the engine kill itself? You'd also have to be worried about a hot turbo cooking itself with an instant shut-down of the engine if you've been driving it hard.

Hi JimX, you asked

"How long after the oil pressure light comes on does the engine kill itself?"

By the time the light comes on, it's too late.
