RE: I need a head job - Legend - 07-04-2010
What are you looking for overall ??
Is this a full race motor or an upgrade?
I'd hazard a guess that your looking at 3-4k on that head for those mods.

i figured as much,
i have a wet nos system which i run on the track but engine has to be streetable when system is removed
basically I want to make the nos system a little more safer when we increase the nos jets which are currently running 60hp jets
bike is currently running fine touch wood but would like the same to ring true when we up the anti
thanks for your interest
oh by the way is this a job for local engineering firm or overseas
regards

Save your dollars and buy a turbo'd gen 2
alternatively you can contact Jamie at SR Pro for all the specific engine work !!!!!!

hey there mate with the laws of the land a turbo would attract way to much attention
The bike has to appear stock as a rock!!
I would hate to pour a heap of money into a turbo only to have it impounded
and as a daily ride its a matter of when i get pulled over, not if i get pulled over
as for upgrading to gen 2 i have been told i can put a gen 1 rear end on so a this may eventuate at some stage but for the moment my line of thinking is i have poured way to much money in into the gen 1 to start all over again so i focus on the what i have got rather then starting from scratch again

So you still want to go ahead?
I can quote something closer to the mark if you want, but it won't be far off the mark.

RE: I need a head job - GRUNTMAX - 09-04-2010
Have you got your own flow bench Leonard ?
I do not.
Gen 1 ported intake This motor made 200rwhp stock bore.
.100 80.4
.200 159.5
.300 223.0
.400 246.5
STOCK GEN 2 Intake
.100 85.9
.200 163.3
.300 224
.400 244
.435 247 ( retainer hits guide)
American Busa engineer's porting Intake Gen 2
.100 87
.200 165.8
.300 230.7
.350 254.1
.400 266.1
.435 268.5
If one cylinder is down on power, with CNC machining, they know it is not the porting and that takes a variable out of the equation---however----if your doing it by hand porting tools---just CC each port, then trim em all up to the highest port CC number.
Pity the Thai Head Polisher has gone on holidays
This Busa was a 300 rwhp S & R Pro Intercooled Turbo.
Hardly a Pig Magnet due to the exhaust stack. After all, how could they complain, more volumetrcly efficient, more economical, low emmisions.
Unfortunately, it went to Heaven
& the rider went to hell. Not quite back yet though

A "Used Head".
Is it "Straight"?
[attachment=9305]
Oh, forgot to mention, if your really worried about the pigs
emmisions standards & ya S & R Pro Turbo Busa, you could always get Jamie to bung one of these muthas inline in your exhaust stack system. Totally over the top 100% LEGAL. Fuc* Em !"There's more than 1 way to skin a cat"

RE: I need a head job - BLACKZOOK - 11-04-2010
i would expect the rods to be the limiting factor for future upgrades not the head. Bigger valves are a waste of time on yuor setup.
RE: I need a head job - GRUNTMAX - 11-04-2010
Bruce is correct, I reckon, as stuff all cc increase.
Stainless Stock Size Valves / Ferea
Carpenter Valve Springs
APE Retainers, Valve Guides & Seals
Porting
But like Bruce says, a hell of a lot of strain & sudden load on the stock conrods when you bung a bit of nitrous in.
Crower Conrods from NLR Systems
Oh, if it is a Gen2 Head, you'll probably be right with ya stock titanium valves
RE: I need a head job - Legend - 11-04-2010
If it a Gen2 then the first thing to replace are the titanium valves.
