i got a poormans type r and i was wondering if i turbo the motor with that low of boost will i have to get a engine management system?

 

you need a fuel management system

 

generally 5-8 psi will be ok, but....you still need management. did you put the b16 pistons in your motor? high compression and turbo doesnt get along as well as low compression

 

the stock gsr pistons are still in the block. with that low of boost can i use a vafc for my management? also can i still use the stock injectors or do i have to upgrade them?

 

ok then your compression ratio is 9.8:1, which is boostable.

the vafc changes the signal that your map sensor sends to your ecu, which makes the ecu think you are running less load then you are and it advances your ignition timing. IF you run the vafc, use like dsm 450's or similar sized injectors and set the fuel values for your boost rpms to -30%. then u can tune from there. i will advise against this though, and to go to a rom program such as uberdata or turboedit if you are obd0

 

alright cool thanx blackeg . i was also wondering if i run 8 maybe 10 psi how much more hp will i get out of my poormans type r? i ran it on a dyno and i was at 168hp

 

a real rough estimate is that your car will make about 10 horsepower per 1 psi you run, so like 8 psi would give you an additional 80 hp and so on... its a really general way of thinking.

 

alright cool thanx bro
