Ok i Bought a 96 gsr with a blown bottom end so i figuered it was a good time for a b20 vtec setup. So i got a ls vtec kit slap everything on and ran the stock ecu on it. Cranked it on and broke it in but it seem to have noo ***** wat so ever. And when the car gets warm it would studer at mid rpms. Any help would be appreciated..

 

Stock ecu is your problem.

 

why would you think running a stock ecu would be a good idea?

 

At the time thats the only ecu i have. What ecu should i run or do i have to do anything to my stock ecu?

 

You have an obd2 ecu which is not chipable. You will need an obd2a to obd1 ecu conversion harness and run a chipped obd1 ecu with a correct basemap. Then get it tuned.

 

agree with that!! find another ecu bro

 

I took it to my boy's shop and he ran the hondata s300 on it and he all ready had a basemap ready. I ran the car it had a big improvement it did not studder any more but i felt that it was still very underpower my boy agreed with me. But he blamed it on the head he told me it would of bin a better setup with a b16 head.

 

did you actually tune it?

what is the actual setup beyond a gsr head and b20 block?

 

The gsr head has nothing to do with your problem. Tune it for once

 

Jdm B20 block 99 gsr head skunk2 intake mani meagan racing resy. And dc headers

 

tune it

 

Alright, ill take it this week end. Thanks for the help guys. Ill post the outcome of the tune once i get it done.
