If he's "porting and polishing" the head for $660, then he's really only waving a die grinder over it briefly to clean up a few casting dags and that's about it. Either that, or he's got no idea what he's doing and he's just going to hog it out. Refer to my first reply on page 1. I reckon a decent porting job can consume $2000 easy.

thats what i thought thats why i posted that up to show the quote broken down a little -

then i was looking at this -

http://www.lewisengines.com.au/rb-nissan-1/

step 1 and 2 this seem like a good price,

but i am seriously considering this

http://www.lewisengines.com.au/rb-30-25-torque-monster/

Looks like no porting on that one though , try supeflow heads at Liverpool I've seen a rb25 he was doing looked pretty good to me, wherever u go I think you are within your rights to see examples of work. Like in west ends case I know they do some of jems engines but I doubt they will tell you that. Ask who ever you go with exactly what porting and polishing you will get for the price

buy my head, it will save u alot. i got a fully prepped 25 head sitting on my workbench, fully machined for a 30 bottom end.

was gonna use it but i dont know if i can be assed to rebuild another motor.

just get urself a new set of lifters and ur good to go.

i have a garret 35/40 at the moment but considering a change..

looking to run 360kw - 420kw.. may never get that hight but best to build motor to handle

Looks like a stock head would be fine with some Tomei cams

forget porting..my 26/30 makes 400 rwkw with 35r with stock head and stock rb30 block.

just buy this

or lash out and get the forged version

    • Hey guys, Just want some advice on r34 GTT ac system. Since I’ve owned it, the ac compressor, doesn’t matter the set temperature or ambient temperature, runs for around 10 seconds then disengages the clutch, then re-engages everywhere 30 seconds or so and keeps repeating this.    is this normal?   I had it recharged today as it was slightly low and thought it would fix it but still does it. it cools fine in summer even prior to the recharge, except for the usual warmup when stopped or in traffic (still yet to wire overheat fan to on with ac)   any thoughts would be much appreciated 
    • To plug the hole. The engine plant may not have known whether the car it was going into had a gauge or not. It was a long time ago and the integrations might not have been fully modern. Or they might not have cared because the extra inventory and processes to save a few cents on the sender might have cost more anyway. But please tell me you are not still confusing the idea of a pressure gauge sender, and an oil pressure light switch. The switch will be out there. In a separate hole. Probably with only one wire running to it. Running the light.
    • Blower needs to go low on the exhaust side, displacing the AC and PS, which you have to decide whether you want to keep and how and where to relocate if you do. Electric option for PS is, at least, helpful. Sadly, there is no workable 12V electric AC of any value. Whilst the blower is the last compression step before the throttle, and so it might seem a good idea to have it near the inlet manifold (as mentioned above), you probably want it to go through an intercooler first, so, having it on the opposite side of the car facilitates that air flow path. The turbo discharges into the blower, so proximity of the turbo's compressor outlet to the blower's inlet is nice. But then you might want to intercool that too, before boosting it again....which would probably be a ball ache. Routing pipes out to the front and back could be a bit shit. If there was room for (at least) a small (but preferably larger) water to air core on that side, then that would probably be the best approach. I guess a reasonable alternative would be to locate the blower where the alternator is (more or less, associated with the inlet manifold, per Matt's thought), and somehow incorporate a water to air core into the manifold, sort of like they do for modern blown V8s. The big difference here though is that those V8s have only the one throttle (upstream the blower) and only the one compression step (the blower) and no need for too much in the way of bypass/blowoff valves. Whereas in a twin charged 6, you do need to think about one or two bypass valves associated with the 2 compressors and you would prefer to have the intercooling done before the air has to pass through the throttle. You'd like the throttle to work approx the same no matter what the compression is doing. But if it is located in hot air stream before a cooler, then sometimes the air will be real hot, sometimes it will be quite cool, and the throttle mapping/response will be quite different between those two cases. The throttle, if sized for hot air, would be too large for cold conditions. It's all a ball ache.
    • Package SC on exhaust side. Remote mount turbo. Still a fair bit of room when you get creative on the inlet side of the motor too. Especially if you can get really creative with the welding, and effectively build it into the bottom of the inlet manifold. Would definitely take some design work, and some trial and error, to make sure flow works well still! Might be easier to just start with the Nissan March though... All the work is already done for you...
    • I'll sit down and get a post together 😁
