Ok I'm putting it out there to see what you guys can come up with.
I have $2700 left to spend on her and have a few options.
I know what direction I'm thinking but would like a couple opinions.
Here is where I'm at.
4.2 come bottom end 8.2:1 comp.
Smallish cam.
Stock heads with heavy springs.
Pacemakers + System.
Ported maf and tb.
Mildly ported manifold.
Mildly ported m90 2.8" pulley over driven crank. (11psi @2000-5600rpm)
240kw @ 5000rpm
460nm @ 3300rpm
Running gear is.
Th700 St2 2400 stall
3.45 lsd. with over sized rolling diam tyres = 3.23:1
Will need retune regardless of what I do so lets call it $1500 budget, can be stretched a bit.
Problems are little M90 running very hot and cam too small.
Solution are....
#1. Bigger cam + port heads $1800 ish +9hrs
#2. Bigger cam + IC $2100 ish +7hrs
#3. Hi ratio rockers + port heads $1600 ish +6hrs
#4. Hi ratio rockers + IC $1800 ish +5hrs
So Power+reliability V work+cost?
Opinions please.
