Topic: which engine for the crawler

[boggerunner]

if i dont use the rotary engine, its gonna be up for sale along with the rest of the car, its an 86 rx7 and it even has an intercooler, but i think the rotary doesnt make enough torque, and my truck might be too heavy, what do u guys think?

rotaries are cool and lightweight, but not very practical for crawling.

here is the 22re

and the new 13b

the 13b si really cool but it isn't a torquey motor at all.  I would stick to the 22re if you aren't going to smaller motor.

Yea the 13b isn't a crawler type motor. Now if you were going to be flying across dunes then it would be sweet. High horsepower with little torque not too mention the 9 grand or so redline

22re is tried and true, a couple mods to get alittle more HP and you are good to go.

i already have a couple mods done to it, punched 40 over, flat top KB pistons, 9.7-1 compression 3" intake ported head, pace header, dual row timing chain

Trucks too heavy for a 13b... crawling's about low down torque, not top end horsepower.  Buy a beater vw and throw the 13b in the back. The 22re has (for its size) quite a bit of grunt at low rpms and is far less likely to leave you stranded on the trail or anywhere for that matter. Yes the 13b's can go a long time, but when raped they need rebuilds somewhat frequently. Rape the 22re all day long, it'll beg for more. 

Somewhat offtopic, but when did people forget that rotary engines only perform well in very light cars? Apparently mazda forgot, since the new rx8 in ass heavy for a rotary. Yeah yeah yeah, it's lighter than all the competition, but it's still not light enough. And where's this new rx7 I've been hearing about for years?
