New here & im kinda stuck/ need advice.
So i live in hilo hawaii ive got a 1992 eg hatch w/ a b18c1 750cc injectors gtx3071 billet wheel turbo water/meth injection nothing crazy.
Anyways ive had a ebay turbo Manifold that came w/ my turbo kit & i could see it coming from when i first installed the kit but the manifold had cracked so i re welded where it cracked wich was right around the collector & then ordered a cast iron top mount manifold. & when i got it in the mail first thing i didn was port & polish the runners then painted.
couple days later its in the car all ready to go everything is all the same as far as the tune turbo wastegate etc. after i installed it i took it out for a test drive and man.. there is absolutely no power!! Compared to the cracked cheap mani from before it used to put you in ur seat and once vtec hits ur stuck to ur seat.. now with the new cast iron top mount manifold it feels like Im driving w/ a trailer no torque no power what so ever its almost like im running with the intercooler piping diconnected. As far as the spool up sound and boost gauge i know im make boost.
The car is tuned on crome i have the RTP and moates hulog and as far as the basemap i can change whatever i need to instantly. But i feel like the car should be alittle better right ? Now that u have a manifold thats not cracked ?
