This post will be long, but should include pertinent information needed to help you help me. I am a noob at this, and am looking for veteran experience. I am building a motor for a '99 GS DC4. I have been saving, but need some help laying out a road map for the build. The motor will be a completely seperate build from the motor that is currently in the car. As far as budget I am in no rush as I want to do this right and am willing to continue saving to do that. I am OK with putting in the money to do that as long as I will see results from that investment. I would appreciate you guys and gals advice and constructive criticisms.
Goals:
First and foremost I want this motor to be streetable, long lasting and reliable as it will be a daily driver. That being said I will probably do more preventative things than neccessary to ensure this motor is not completely pushed to it's limits to reach my goal. I am shooting for around 400hp but would settle for more. The car will rarely see the track. If it does it will be the drag strip (mostly 1/8 mile tracks around here). The car will basically be a street toy, so I want to make good power between 20-90mph. I don't want a motor that doesn't show it's true potential until you are already cruising 60mph on the highway, because this will be useless to me.
Subjective plans/ Ideas:
I am planning to go with a B18C bottom end fully built by Laskey Racing. I chose the B18C after talking with Mike Laskey himself about my goals. He said this would be ideal for a street car because it already has the plumbing for oil squiters, etc. I am also thinking about an 83mm bore, because it will give me room for rebuilds down the road, but still make good power now. I have heard 9:1 compression would be good for my goals, but I honestly don't know. Also you can choose between Manley or Pauter rods on his build. From my research I am leaning towards Pauter.
Advice needed for the entire head. For the head I am stuck between a GSR and B16 head. I believe the B16 head flows better (correct me if I am wrong). I am unaware if this head will bolt directly to the B18C bottom end without creating issues though. Whichever head I choose will be sent to Portflow to be machined. As far as valvetrain I am at a complete loss. I know Portflow deals with Supertech a lot, but have heard this is not recommended for street cars. Again, I am looking for power and longevity. Cams, clueless on what would be ideal.
I am definitely going with one of the Edlebrock IMs, but don't know if the Performer X or Victor X will be more suited for my build. I plan to have it port matched to the specs of the head as well. Now obviously this leads me to finding an appropriate sized throttle body.
Turbo ideas. Well, I know the t3/t4 is popular for street driven cars, but i have also heard a lot about the GT30 and GT35s as well. I am interested to hear what turbo you all feel will suit my needs best and why.
Any more questions to help narrow down things, just ask.
RECAP:
reliable
longevity
streetable
around 400hp
majority of power seen between 20-90mph
not tracked, street toy.
