The $7300 is only for the FG stage 2 I think the B series cost a bit more. FGs seem to be a lot cheaper to make fast initially.

Correct, $7900 for a B series.

with a motor like that you will want to chase over 450rwkw. Go a full 4" zorst system else if you go a 3.5" that will be limiting your power outcome.

full built motor + goodies + to4z == 4" system

Thanks for the info guys. I could go for 450rwkw plus but this engine is going into a XF which will be roughly 500kg lighter then the previous BF it came out of. I definately think the To4z is the way to go, with either a 3.5 or 4 inch system strapped on will be a killer setup. the engine and box I picked up has all the stage 3 gear inside, stud and girdle and billet oil pump gear and the stage 2 gear strapped on also twin plate clutch. will be selling the I/C and piping kit and going for a plazmaman and aluminium I/c piping mad to fit into the xf, will be rolling and flaring the rear guards to run 11 inch wide semi slicks to get the power down.

Nice, should be a weapon at the strip.

Thanks mate, still a while away but I cant wait for the first drive

Mine is Nizpro Stage 2+ with a couple of extra bits. Yeah there may be better bits but I drove in and drove out and Simon is always there to answer questions and doesnt talk sh!t.

My dynoed at 372 but there was 12 - 18 kw of wheel slip which didnt get "added on"

In any case I know I'm fully EPA compliant and it looks the good to me. The driveability of the car is oustanding. Taking the kids to school its just a normal BF.

I do like the Plazmann coolers and my surge tank is a Process West. But I will NEVER say another tuner or another brand is crap but people seem to want to say that about Nizpro. Always amazes me.

Anyway mate, if you have a Stage 3 motor it will go like a cut cat if you do the right stuff with it. Call Simon, explain what you have go and he will direct you. You should probably take it back to them once you have it fitted as they will have the file on the engine and what has been done to what and willbe able to compare it to the original tune. Simon is blunt so be prepared for it but he tells it like it is.

Sorry if others disagree. I don't wish to get into a blew about tuners and who did what to who. I agree Nizpro stuff is expensive but I made my choice. The guy asked about a Nizpro engine. I'm just replying.

Cool, I have the build on another forum and steve I think from Nizpro actually got in contact with me to say exactly what was done to the engine, I had no idea when I bought it as a stat writeoff that anything internal had been done, I did get away with blue murder in regards to the price and nearly fell over when told how much had been spent on it. I will be talking to Nizpro soon once the engine is fitted to see where to go with the exhaust and turbo, am also considering some Atomic Cams to make the little bugger a little grumpy on idle. I wish I didnt have to be at work so I could get my butt home and have more time to work on the body to get it ready.

Sounds like a bargain mate. Really does.

How are they EPA compliant? Isn't the factory cat pretty on the limit anyway? So if your cat is even slightly more high flow (which I assume it will be) then that is illegal.

The stock tune is pretty close to just under EPA as far as I no, BUT once you start to add more boost and aftermarket tune you do start to see better fuel economy from them as the airflow is increased, that's until you lay your right foot into the floor. Ive definately seen some 350rwkw XR's getting around that have heaps better economy then stock
