Hey all, I'm trying to decide whether I should go high compression with my 200, or go turbo... so I'm trying to map out a plan for a relatively cheap/simple small turbo setup before making up my mind. This is just a street car, so I'm looking for good low/midrange performance and reliability, but I wouldn't mind taking it to a track sometime. My goal is to get near 200hp.
Here's what I've already done to the engine:
Bottom end - stock '66 200 (rebuilt), .030 over. Comp Cams 260h cam.
Head - large log with direct mount 2v adapter, 1.75 intake valves / 1.5 exhaust, 3-angle valve job and mild polishing, dual springs with dampers
Exhaust - headers to dual 2" pipes
Ignition - DSII with MSD 6A
Carb - Autolite 2100 1.08
Compression should be about 8.7:1.
Plan:
Turbo: I'm considering a TB0330 Grand National turbo... I can't find a map for it, but engine size isn't too far off and it was built for carbs. Appears to have an internal wastegate of about 7psi.
Carb: I'd like to keep my Autolite 2100 if possible. Do I need to do anything else other than putting in a nitrophyl float and get some richer jets?
Ignition: MSD makes an expensive boost controller that works with the 6a... but can I just limit my total timing with my DSII instead?
Fuel: At 7psi do I need to do anything special here? Can I keep running the stock mechanical pump, or do I need to go with an electric one?
Exhaust: Split the downpipe into my current dual 2" pipes
Intercooler: As a first pass I was hoping to not put one in to keep costs down. If I decide later to swap turbos and go with higher boost, I'll add one in. Would I notice a big difference without one at 7psi?
Sorry for all the beginner questions but I'd really appreciate any advice... I'd love to do this if I can convince myself it's worth it.
