Difference between rb20de and rb20det blocks

[skylinechef]

]Just wondering if anyone knows if there is a difference between the turbo and non turbo blocks. Im aware the pistons are different, but is there any other difference. If no one knows can they tell the measurments of the stock rods of a rb20det. And the crankshaft. Reason being ive got a non turbo block that i want to rebuild with forgies ready to put into a r32 so that its fresh, clean and strong. Im obsseive when it comes to reliability.

And also is there any other pistons you can use.

Please help guys and girls im desperate!!!!

I have the same blocks in my race car. They run 10.0:1 compression with the different pistons, but the rest i beleive is the same for the turbo block assembly.

10.0:1 is great for a street car, but limits your available boost pressure.

Valve springs could be of lesser tension than a turbo motor.

It would be good to really know for sure if the bottom ends are the same as the turbo engines.

There are no oil squirters in the NA block and you need to replace one of the bungs in the side with the line fitting off the turbo block.

Yeh thats true about the oil squirters, but I think they are only a benefit if you go circuit racing. It's not a real big issue in a drag racer.

They can be fitted with some slight machining to the N/A blocks.

I didn't bother fitting them when I turboed my NA motor. No real need.

thanks guys. Just have a n/a block and are about to move to sydney from ChCh NZ. Seling gtst. Want to build a strong bottom end for street car when i get back. Do yous reckon a n/a bottom end with forgies will hold up to say 220rwk.
