When i bought my Z at the same time my best friend bought his 135I, i came from sivic si and he came from G35, well he mooded his bemer JB3 then JB4 chip we actually put them in together all i did to my car was changed all fluids And i do have the sport pakg also does he.
Now till this date am driving my N/A engine were his turbos now pushing 17psi after the JB4 install, well car starts braking, downpipe craked he bought a new one then intercooler craked he brought a new one then fuel pump went he bought a new one then in the same week me and him crashed our cars
1 month later we where back on the road.
two weeks ago his car died again starter went cuz his car keeps dying allover the place i think the pump is going again well i still drive my N/A after the crash and still drives like new and i got 12k miles friend got 14 k miles, i have to admit it the car makes lots of touque in low rpms than Z and makes aroung 450whp at 17psi wich is very nice, BUT when i let him drive my Z the first thing i hear from him is " man i miss this car, keeps reminding me of my G"
if u get 135i and mod it All i can say is hope u got a deeeeeeep poket, Me and my Z i still like it more than 450whp 135i, cuz it feels verry frigile to me where the Z is like GGGRRRRRRRRRmmmmm MRRRRROOOOOOMMMMMMMM yeah that feeling i like it more w/ my louzy 280whp
hope this helps pal, He still loves his bmw but weit till i get my twin slugs then gooodbye bemer in my mirrow hahhhaa
