Rb26 Blown Head

[i hate rav 4's]

Hello all,

As the title suggests, I have a cracked head on my 92 r32 GTR. I'm not very mechanically minded (being more than 2 moving parts involved) and was wondering what the better option would be: a new motor altogether or getting another head? A balance between cost and not having re-occuring issues. Probably shouldn't have bought anything from Bankstown, but any import would be appreaciated.

Depends.

If you rebuild then at least you will know the condition of the engine overall.

It may be cheaper to buy and drop on an RB26, but you'll be relying on the word of the seller... and in most cases if it's an RB26 it's probably got a history... that being said, you could always end up with a good one...

Do you know if the head is cracked or just the head gasket gone? If its cracked then youll need to buy a new head, if the head gasket is gone you could just replace it, or if its damaged the motor in some way then youre stuffed

In all honesty, for the price of an rb26, you could do a basic rebuild and know you've got a good motor. Hell, you could even have a forged bottom end for the price of a decent rb26 if you know where to look.

Also keeping in mind, replacing a 32 gtr motor with another 32 gtr motor is a disaster waiting to happen. I would recommend r33 motor or if you have to go with 32, at least get an oil baffle plate and some sort of oil feed restriction as thats the most common thing letting them down. Yes the 33 and 34 motor suffer from the same issue however not as extreme, plus the age of the motor is another issue, and not knowing how the second hand motor youre buying was treated... I believe the 33 and 34 also have a slightly different crank and a different oil pump from memory.

Bottom line, for the money of a replacement r32 rb26dett (roughly 4k + removal/installation) you can get:

CP forged pistons

Eagle rods

Piston rings

Wrist pins and locks

ACL race bearings

ARP complete stud kit

Cossy head gasket

N1 oil pump

Oil restriction mods (depending on what you want to do with the car)

new timing belt etc... (if needed)

engine in/out, a bit of machining if you need and assembly.

And even then you should only be looking at around the 3.5k mark... this is just for a basic bottom end jobbie. Again depends who you go to for all this work and how much they charge to do it all but if you look around or know people you could easily do it under 4k.

Depending where the crack is and how severe it is, there's every chance you can weld the head.......we used to do it all the time with great success.
