Whats The Max Rwkw U Can Gett Out Of A Rb26 With Stock Bottom End


Recommended Posts

Had 350awkw whilst on stock bottom end, when we pulled it down (due to oil pump failure) it was still in perfect condition

Don't doubt that you could make over 400kw, but I'd imagine you'd be running some risk

This is a question that often belongs in the 'say what I want to hear' / ' I can't afford to run the powerful car' category

If you want to rely on the old stock engine in the old stock car then the limit is really around/just above where the stock turbos run out of puff or the size of your bank balance. You see, if it matters that the motor breaks then you have the lower limit of power. Alternatively the question is answered; power level = 'lets see if it breaks' when you have the finance not to care.

Someone I know ran a 10 with an unopened old stocker. If you have another motor waiting and own a car trailer then you have nothing to worry about.

The ideal is to look at 300rwkw or under and do as much as you can to make that power with the least strain on the old motor.

Further up the power level is a list of stock bits that will also fail according to application.

You have a R32 GTR.

Motor is what, 16 years old now at a minimum.

What MAX power can you make? Probably over 500rwkw for one dyno run.

Reliably however, 300-330rwkw would be a pretty good limit to set given the age of the motor

Other than that, its the age old 'how long is a piece of string'. Some fail at less, some more.

If you cant afford the rebuild, then dont chase power (rebuild = min $12,000 round trip including turbos etc etc)

i would say adding another 100 would be safe. i am conservative with rb26 cos i think with my pockets.

i have seen them with around 400 but its not an everyday car its driven once a month maybe. at 300alkw u have a very zippy car on the street and running very little risk.

With the stock turbos you should be able to make about 240rwkw without blowing the ceramic turbine wheels to bits.

Or go for some GT/SS's and provided you have computer/injectors/fuel pump you could be looking at 300-320rwkw on a reasonably safe 1.2bar.

With 1 bar boost on stock turbos, i made 265rwkw.

How long the stock bottom will last depends on how well the engine was maintained.
