Get a copy of last month's HPI mag (No. 51 with the gold Supra on the cover). It has an article comparing the three generations of RB26s.

the later the engine the more power you get out of it as quoted in hpi no51 its a good read

everything has pretty much changed at the microscopic level it says

Not sure about 32 - 33 differences, but there are a few when going from 33 -34.

First there are slightly different camshafts.

Second the 34 uses ball bearing turbos which can run about 1.2 bar fairly easily and also make a good power increase compaired to a similiar setup on a 33.(The 34 I sold was making 1.1 - 1.2 bar with just an exhaust and I think the restricter removed from the boost controller.

Don't know too much about the differences but like someone said above there is an article about it!

Personally I found the HPI had *no* detail of the changes....just their note that the later cars made more power.

yeah but they wrote alot about nothing so i still read it lol

5. Stronger valve springs

6. Better dumps

7. Better cat

8. Lighter/stronger pistons

9. N1 oil pressure relief valve

10. Squish zones in the combustion chamber

11. Coils
