Good Day all
Ive got a 89CRX Hf with a JDM GSR in it. Very reliable and fun. I am considering a Jackson Racing Supercharger. I'm using Hasport mounts. If anyone has this combination can you tell me how much modification is needed to the Master Cylinder, rear frame and also what to do about the heater hoses and heater valve. Can this be done without relocating the heater core?
Thanks in advance, Ken

 

it surely can't be much or any mods needed to use it seems like replacing the intake manifold

 

It is in fact a little more involved than you think.

OP: Have alook at this huge thread. You'll find the answers to all your quesitons, as well as a bunch of people running the exact setup you are proposing.

Can anyone guess a t HP numbers with 5 or 6 pounds boost? Its a JDM so it has like 10.8:1 compression ratio, Iam wondering if this is a good thing or bad. I plan not to go over 6 psi as I'm not intercooling.... yet hehe

 

here you go, your welcome ;-)

A good 230 hp with 440cc injectors a few bolt on- short ram ,headers ect and dyno tune, your comp. is fine. i tuned a n.a gsr motor with a 11:9 comp!! with a jrsc @5psi= 230

actually i think the jdm gsr's are at 10:6 compression which from what i read is near optimal for a JRSC, not to high and not to low. let me know if you have any questions on the build, oh and good luck with the alternator pulley clearance....that ***** a biaatch!

 

I was wondering about that. Does the JRSC come with a bracket to relocate the alternator inwards? It almost looks like it has to cuz the belt that runs the alternator is on the outside most groove on the alternator and the SC is run on the inner grooves. That being said, the outside groove still has to line up with the inner groove on the crank pulley. which means if it fits now, it should fit later. So, the alternator is relocated toward the rear of the engine by the width of the SC pulley grooves ...Yes???
