N/A MIKE

I think Im going with a R33 intake manifold, adapter plate, RB26 itb's, runners (undecided length), bell mouths, maniflold type plate (with bell mouths nicly set in), and im thinking CARBON FIBER manifold and 4" intake pipe down to a Q45 afm (or 2 ) and massive pod in a cold air box. I think I will run individual vacume hoses to a colector to use for brake/fuel pressure, Im going to see how the gtr's get around this + idle. Im doing it on the cheep for now as I think me jobs going up the s#!tter . No job = more tinker time in shed :laughing-smiley-014: More tinker time in shed = less cash money for toys Less cash money for toys = less things to tinker with in shed Less things to tinker with in shed = god forbid more time spent with the misses (this has its good and bad points, lets not forget wink.wink) More time spent with misses = will lead to arguments over unenployment and it will just spiral down from there realy Found a thort inspiring page in the states though http://www.rossmachineracing.com/intakepartspage.html filled my head with ideas Insperation from BMW and honda

when I put my foot down I dont want the itb's to have to go looking for air through th intake pipe and filter, with a larger plenium there lots of air in it to feed itb's, beter responce??, thats my theory, if anyone knows a beter plan im all ears though. Iv herd a few bad things about those greedy copies, like ports not lineing up well and very rough casting which causes problems, and in one case a gap in the casting, looked like a crack.

Yeah thats just what iv been looking at, max re-grind 8.3mm lift and 273deg, or something like that, im prety tired . Im glad the Q45 worked out for you mate, Iv been alitle woried that it wouldnt messure on idel + now I think it will work mint with the RB26 itb's, mite ditch the RB26 plenum idea now, found out thay only 4.1L volume, I think I want a minimum of 6L. May look at a custom alloy or fiberglass/carbon one, perhaps shape it abit to get a larger volume. ---- SORY MY TIRED ASS MISTAKE, MAX REGRIND OF STOCK CAMS 8.3mm lift and 255 duration---- Check this link out http://extrudabody.com/ got some neet ideas.

see my other post to get a beter idea of what im doing. http://www.skylinesaustralia.com/forums/It...cu-t206781.html

Any run one on an N/A?? 2.5L or 3L Im alittle worried about low air speed readings at low rev/ideling.

The way I was looking at it was similer to having itb's with a cold air box (the gtr plenium) around them, with a afm messuring the air going in to the box (plenium), if you get my drift , the Q45 being bigger and giving less resistance into box(plenium). Iv done alittle resurch into plenium ideas and the rule seams to be 1.5x air in plenium than in engine i.e. 3L engine/min of 4.5L plenium, sound right?. Looked in to trumpet design and length alittle to, jury still out on that though. I haddent realy thought about the AFM and low air speeds, any one played with a Q45 on a N/A???, when I did my GTS25 I was woried about keeping the air speed up into the cilinder head from the tb (standerd over head plenium). I just assumed with itb's close to the ports this would be less of an issue?. Im in NZ, so legal smegal RB26 heads are expensive over hear upto the 2k nz mark (no intake or exaust), compaired to R33 RB25de's around $300 nz. I can get a RB26 throttle setup and plenium, inc addaption for the R33 head for around $1000 nz I will be trying to keep the cost resenable, planning to use minimum safc, E-manage or ultimate. Cam gears ,no vct, sticking with standerd cams and get head checked but no head work for now, going to get my rb30 rods and rb25de pistons checked, if ok will use those + new rings ,block checked, if ok acid diped/painted and lightly honed, crank checked and balenced and a crank coler installed then put back together with new berings, oil pump, water pump and what not. Going to get a 4WD sump adapter from Pro engines, there real nice units. And plonk it all into a R23 GTS4, hopeing to be a real nice driveing car, im not super fond of turbos, twin turbos is a diffrent story but a diffrent price bracket to. will run in with RB25de injectors and standerd ecu(maby safc if I go with Q45 afm), but will up to RB20det's and looking at E-manage unit after run in.

Just to point out that I don't want to use the Q45 AFM for more kw's, more for less restriction upto the rb26 buterflys, hopefully not losing any of the responce of the ITB's. (saveing my self from sum smartarse overkill comments )

Guess I could ditch the trumpets, use an RB26 plenium modyfied to 100mm intake, run 100mm alloy tube down to a Q45 AFM and a big pod in a cold air box??, and use a apexi SAFCII to tune it all together

Hi guys Long time reader First time poster. Im building a rb30de and have costed out an rb26 individual throttle body setup, Trumpets, RB26 throttle bodys, RB26/RB25 adapter all for a good price. My question is how to run an ECU with no AFM and individual throttle bodys??? If I linked all the intakes together (with an alloy pipe T'ing into each intake or a custom sandwich plate which links them all together) between head and butterflys, would this equel the pressurs across the cylinders/intakes and enable me to run a MAP sensor at one end or the center?. 6X MAP sensors, one behind each butterfly?. I could put one MAP sensor one the worst cylinder and tune all 6 to that one? (not realy my idea of a good plan). Or am I making this all to complicated and theres an easy way past this?. Cheers Mike
