so i am 3quarter done turboing my lsj and the saab intake manifold i have i cant find a map sensor that fits mmy lsj stock map is to small the hole to big?? wtf? what map do i use for this saab intake manifold??

 

The normal GM late model MAP. It also happens to be the same map that is located on your blower right next to the throttle body. You will have to re-scale your map to have it work since it is only a 2 bar map (15 psi limit) TO get more you have to find a 3 bar GM late model map.

 

i dont think i have that on mine i gotta check im not too sure

 

All balts have it on the stock blower.

 

Are you referring to the SCIP sensor?

 

i think he is one of my sensors we took off/ is not being used currently.

 

ANd when you use it you'll also have to put an iat sensor somewhere in the intake stream after your intercooler. Then splice the connector from that map and that iat with your stock tmap harness, using the same ground for both of them.

 

sweet thanks a ton guys, idk the map position on the underside of the saab IM is to big my stok map sensor dont fit so imma try some sort of gasket or o-ring to fit it. and any idea were to find these 3bar map from gm

 

leafy you got no clue what you're talking about you're talking about the scip sensor which gets nixed in a lsj turbo swap, the map is on the intake manifold.

 

I thought the same thing lol, the SCIP sensor cannot act as a MAP sensor its the supercharger intake pressure sensor, most turbo LSJ guys get ride of it and turn it off in HP tuners, although i have heard of it being run, certain turbo LSJs dont like running without it.

 

in order to take this sensor work on a stock lk9 intake manifold you have to build a spacer bracket to hold the sensor and use an additional o ring, imo just buy zzps already modified one

 

Yes but he's using the saab manifold. SO you take that sensor, cut the connector out of the harness, cut the TMAP sensor off the harness and wire that connector to the map part of the tmap harness. Then wire a separte IAT sensor onto the IAT part of the TMAP harness, you will have to share grounds between the two since the TMAP only has one ground for both sensors. I know because I did the exact opposite wiring when I put the blower on.

Or you could just wrap the TMAP in electrical tape and then shove it in the plug on the saab manifold and drill and tap the saab manifold for the 8mm bolt that holds the TMAP down. This way is a lot more ghetto and a lot less correct.

 

i did i bought the already modified one bud, idk ill look tomm when i go in but the hole was still big?

 

no

take a picture and post it up man

 

Ya take slowlines advice and post a pic, I believe on the zzpp modified ones the map sensor is located on the bottom side of the mani, your using that one correct?

 

it should be on the top right of the intake manifold if you are facing the motor..

 

might be on yours, not sure, but all the new ones i know they're welding into the bottom
