a1awind Posted July 13, 2013 Share Posted July 13, 2013 i want to be able to wind out for acceleration and highway driving. with no tach... does anyone know what rpm the 2.5 5 spd 2wd runs out to in each gear? i.e ...whats the max speed in each gear?. also...does the 2.5 idle rougher than the 4.0? it seems like mine idles a little rough.

Geonovast Posted July 13, 2013 Share Posted July 13, 2013 Why not switch to a full cluster? Link to comment Share on other sites More sharing options...

88whitemanche Posted July 13, 2013 Share Posted July 13, 2013 Coolant temp sensor and oil pressure sensor Link to comment Share on other sites More sharing options...
a1awind Posted July 13, 2013 Author Share Posted July 13, 2013 Coolant temp sensor and oil pressure sensor my cluster has those. the only blank gauge is where the fuel gauge is on the model with a tach. Link to comment Share on other sites More sharing options...
Blue88Comanche Posted July 13, 2013 Share Posted July 13, 2013 Then its pretty much a direct swap. Just make sure you have the correct year cluster. If you get a cluster from a 4.0 it will need to be adjusted for the 2.5, but I can't really help with that Link to comment Share on other sites More sharing options...
Harley Posted July 13, 2013 Share Posted July 13, 2013 or buy a tach for around $35 Link to comment Share on other sites More sharing options...
Eagle Posted July 13, 2013 Share Posted July 13, 2013 Tell us what RPM you'd like to use for your shift point and I'll work up the speeds in gears. Link to comment Share on other sites More sharing options...
a1awind Posted July 13, 2013 Author Share Posted July 13, 2013 well...if i know redline rpm = speed in every gear...i can figure it out on the fly lets say hypothetically 3500rpm = redline so what I'm looking for is ( 3500rpm = 25mph in 1st, 3500 rpm = 35 mph in 2nd .....etc etc.) Link to comment Share on other sites More sharing options...
