Rb20det To Rb26dett

[PhatMike]

hey everyone ive found a reasonibly cheap imported r32gtr and im thinkin about buying it and doing the engine conversion in my mazda b2000.i currently have a rb20det in their with the rb20 box with an old link ecu.

is the rb26 any bigger than the rb20?would run it with standard turbos,gtr sized cooler,3 inch exhaust etc(just the basics) what sort of power would you expect?also would you wire up the standard ecu or go aftermarket? anyone thats done a rb20 to rb26 got any tips on what needs to be done?

any help appreciated cheers mike

standard r32 gtr with catback and pods make 280rwhp. Rememebr GTR has factory front mount, i would b using this rather than an aftermarket one. Also u will need an rb25 box (bolt straight in) cause the rb20 box will also bolt straight on but it is alot weaker. The gtr box will be no good to you as it is for 4wd.

and you can use the gtr box, just got to cut and shut the trasnfer case. been done by alot of people. GTR boxes are alot cheaper then 25's and just as strong.
