Thought I would do abit of an update, Its been a while. Its funny when your building a car how plans change, goals change. Nether the less it has snowballed big time, I remember reading on the forum how everything will cost 2-3 times more than you think and will take double the time and thinking what a load of sh*t but as it turns out its true. The engine still hasn't been built im sorry to say, From what started as a basic bottom end rebuild, with a set of rods & pistons has turned into something much much bigger. Originally I had a modified / hybrid Holset HX52, Which I was going to run, But decided against it earlier this year, Sold it to a friend of mine along with the manifold, I was eventually going to pickup a GTX45 when the time was right. But a couple of months ago the local Garrett Dealer here in NZ was having a big sale, They had a couple of GT4718R's for $1700 New with a rear exhaust housing it was to good of a deal to pass up. Obviously with a such a big snail lag is going to be abit of an issue, I am going to step down the runner size on the manifold hopefully to combat some of the lag, Will be running the smallest rear A/R available (0.96) Should hopefully fingers crossed make 1000whp with ease, Having the billet crank will also allow me to rev it out more to take advantage of the GT47's powerband.
The Bottom end will consist of
CP Pistons 9:0.1 Compression Ratio
Spool I beam rods 7/16 ARP2000 Bolts
Spool Imports 4340 Billet crankshaft (Factory stroke)
Spool 10mm Girdle
ARP Bolts all round
Still undecided on the head, I am pretty set on a CNC port, But IMO it seems like abit of waste to do all this port work and leave the factory valves in there. From what I have heard the factory seats only cater for 0.5-1mm Oversize, And replacing 24 seats can turn into a very pricey exercise. Kelford cams here in NZ, quoted $85 for an aftermarket seat X24 to suit bigger valves nearly double what I had been quoted in AUS from similar cylinder head joint. I am thinking of picking up some Supertech Inconnel exhaust valves (1mm OS) and a set of 1mm OS for the intake also.
Also managed to score a GTP brembo setup here in NZ late last year, Which I was stoked with. 6 piston front & 4 Piston rear.
