i have a blown gsr motor and i wanted to swap in an ls motor into my car while i rebuild my gsr. is it a direct swap or do i have to swap ecu's also?

 

also wat about all the sensors that hook up to the gsr motr. will they all hook up to the ls motor?

 

anyone?

 

yes it is a direct swap all sensors and ll you can use the gsr ecu though i would neer recomend it

 

why wouldnt u recomend it?

 

because gsr fuel tables are different thn a ls ecu plus the added fact that the gsr ecu is a vtec ecu and teh ls a non-vtec ecu so you will have a check engine light. plus personally i think it's half assing it and here at Honda Evolution Motors Sports we try our best to not skip corners

if you keep it under 4k rpm you should be ok. anything over 4400 will make the run rich, because that's when vtec kicks in (more air).

 

its only temperary so it wouldnt be half assing it cuz im mean i gotta get to work some how to make money for building the new motor. but thats besides the point. so the bottom line is that if i stay under the vtec point, it will work right.

Yea , you dont wanna hit vtec , on that LS motor , slight chance you might blow the welds on the intake manifold

 

just get a LS ecu they are cheap

 

and the redlines are different so that computer will let that engine rev alot higher than the Ls ecu would , you might want to get a diff ECU cause even with an LS you will want to put your foot in it every now and then. Better to be safe than have 2 blown motors

 

i swaped my 99obd2 ls drive train into a 94 GSR, used a 93 ecu, worked perfect first try

Since he's putting in an ls motor and using a gsr ecu the gsr ecu will give him the vtec cel codes and therfore not let it rev till redline. Even if it didn't have a dual rev limiter u would hope he would be smart enough not to rev it to 8000 rpms, all about being smart and having will power.

 

just sell your gsr ecu and buy the ls one and have lunchmoney left over

 

why would i do that. i need the gsr ecu for when my gsr motor is done. im gonna see if i can pick up an ls ecu to go with the ls motor when i head over to hmotors to pick everything up.

 

well if your building your motor why would you keep your gsr ecu? and not get a chipped ecu

 

u have a point. i was plannin on keepin the stock ecu and runnin a hondata s100 on my built gsr motor.

 

i got one if you need it...either pr4 of p75 take your pick

 

i have a p75 obd2 ecu if you need, check my isignature
