Chad fitted those rims today great fitment on the front still have a little room too

Yeah I should start looking for some 18" rims that will fit over brembos that are reasonably light (track use only)

keep your ear to the ground Steve & others please......they'd need to be between 9" & 10"

not quite, as i told you the cam timing was due to the TDC marking on the cams being out several degrees

I have read however that some belts do stretch, however this is only during acceleration and only by the very smallest margin - once the belt is running the cams on a standard or decelerating speed they hold their shape - spoke to several mechanics about this and they agreed it was all a theory that whilst true, didn't make any bearing upon the timing of the engine as a whole

-D

Edit - to add to petes post, why bother porting it at all? the gains are negligible and not worth it unless you're chasing that extra 1/10th a second around a track - waste of money on a streetcar but if u got the coin to spend a couple g's to get 5 extra kw then cool

Must disagree with this Ben...I had a supercharged L20 in a stanza at one stage and my mechanic had the exact motor except his had a ported head and it went much much better, there is some gains to be made in the head, like Luke said if its off do it why not

i think it depends on the motor too - some come out of the factory with pretty well designed ports... ill have to think about whether its worth doing - i'd have to see how much porting on its own costs on top of polishing and all the rest - all comes down to how much money is available ;P

Na Chad slightly different but that's cool there not a forever rim

will do Pete

[Carbon 34]

as I said to you the other night Abe before I had to rush off, light porting ie. removal of lips and ridges etc are fine to do at home but any major porting should never be attempted without a flow bench and the ability to cc the ports & chambers...also, get the seats machined (or inserts replaced) after, not before cause I've seen too many slips of the stones and burr bits ruin good seats

agree with Pete

you port,polish,cc heads for many reasons besides max KW, like removing any spots that could become "hot spots of carbon build up" to remove a possible weak spot in the casting due to harmonics of the engine hitting resononce from excess casting runners

not to smooth out the intake to a polished level, fluid dynamics is better with the little sand marks in it still. minus burrs of course. on the exhaust it's another story, smooth is best to keep the air from tumbling,creating turbulence plus to remove any cast flaws on the outside for the above reasons, and to make them look nicer when installed.

with care you can do a pretty damn good job at home of MOST of it , without changing the shape of the runners and thin spotting the head coolant jacket area.

clean up coolant paths as well, and of course oil control

check for cracks around the valve seats in the port runners near the valve seats

really if you know anyone in town who has a fluid /grit porting machine like squeezing gritty toothepaste thru the ports , can't remember the name of them,,, lol those work a treat

if this gives you an idea of the cost,, in USD for RB26.... DIY can look pretty damn good if you have any clue how to do it.. which I'm sure a lot of us old farts know..lol

Offer still stands. My works are fairly light, cheapish and dead square inbetween 9 and 10. You can come try them to see how they fit.

[skwiz]

Is that an automotive way of telling me to harden the f**k up?

yes. Just hit boost a little harder. you won't hear the belts then!

[typevu]

Yay or nay?

[Madaz]

I like it

[Carbon 34]

Nay, needs to be smaller font and overall, but concept is better then any of the others

Wouldnt know where to start. I have absolutely zero mechanical skill. Wouldnt want to stuff it up. Rhemac does sound good for the price tho

got any pics Adrian....what offset are we talking and maybe PM me a price

My BITSUS Customs air/oil seperator just arrived, personally delivered by the man himself in the GTR

That "dent" is there for a reason, it's to accomodate the crossover pipe on an RB25, check and you'll see what I mean.

As for the Gates belts, yeah, they whine, comes part and parcel of those belts I'm afraid and it's well documented.

If you're going to get it ported, go to Rhemac, speak to Mark. They are the guys to see, do awesome work, reasonably priced, know their shit and best of all, right here in SA! They did my 26 head, came up sweet!

So that dent is meant to be there?

[heslo]

Sure is, re-read what I said and check it on your covers too. You'll see what I mean

[Bl4cK32]

anyone know the cheapest / best place to get an apexi pod filter kit for a hcr32?

Spot on, its there to clear the bottom of the throttle body/hose
