My vs cam gtp was 310whp, My first xp build was 334 and ran 12.7 @ 110, my second xp car was 347 and ran 12.5 @ 113 (with no traction). My stage 3 heads/ cam build was good for 400whp, but got de-modded to a daily driver before I could dyno it or get a timeslip.
@killdac You may or may not feel a difference, but you will definitely kill a ton of KR and set yourself up to drop a pulley size or make safer, more consistent power on the pulley you have. Just take your time & make a smooth flowing, low resistance path for the air. You're definitely doing it right by porting the TB also! Just don't over port. Good luck!
@JoRoW99 Are you talking about the bolts that fasten the coil to the bracket? Yeah I've never heard that one before but thanks for the heads up. You should post up a video! What kind of 3800 car is it?
That's EXACTLY what I did to my blower in prep for my top swap. You should post a video about the results of you're porting. I used a Dremel to port mine. What did you use?
Just know that touching the silenceng ports has been known to decrease power And efficiency on M90's. I'd rather have a fast car then 1 that sounds fast.
@killdac Honestly the LS1 is a BIG ASS throttle body for a 3.8. Probably overkill for most setups over a 3 inch pulley. A ported stock one will net you some good throttle response and top end with your mods. And LOL at the modding bug. Man look at me... I'm a mess!
@mrsarcastis13 No problem, i just tapped the holes for the old screwed. Im wainting on injector connectors still so ill make a video when its done. Its a 2001 GP GT.
Nice. Well i subscribed to you're channel to keep and eye out for that video. Try a JY for a L67 harness and cut the injectors off that. Might be a little cheaper than ZZP.
@mrsarcastis13 Hey just a heads up, The screws from the L36 coil pack dont fit into the L67 coil pack. I just top swapped this weekend and found that out but ive never heard it before. so watch out.
@Maxmaj1q Do YOU personally do PCM tunes and Blower porting? I'm in Chicago, and I call everywhere, and they all don't know what the hell I'm talking about when I ask them these questions. Lmao.. I'm top swapping my Monte soon, so I'm just curious.
Word. I used pretty much the same thing. I'm gonna be posting a top swap video here in the next couple weeks. The owner of RegalGS.net forum is gonna have a little/local mod day to help me out with swapping it over.
