450sx part 2

[irax]

older 4 cam v8 just get called quad cam, mostly because that is what they were called at the time. to say a car had a quad cam motor implied that it was atleast a v6

[gsracer]

Heres some pics, surprisingly it only took a few hours of fabwork and bracketry. All i need is an intercooler and a tune and i can drive it, intercooler is en-route, tune is what im missing/ dont know where to get.

Good thing that car has a DOHC motor. The guy you quoted was right. A "quad-cam" car with two heads is still a DOHC setup. Just as how a "twin-cam" car can still be SOHC (i.e. SOHC 4.6 liter modular motor). Quit bringing up stupid stuff in this thread.

And I totally agree with southerncross. I can't wait to see this beast in action!

hey mate, as i said via pm. i think ya car is tops. i've been hesitant on what set up to do on my s14 (twin turbo of supercharged or trumpets). this however has made me a bit more happy cos i now know it'll fit.



this is my s14 i'm building. and i also got the mazworx kit. but because i'm in australia, and we drive on the other side of the road, i've had to get rid of clutch master cyl/booster.

but one thing i wanted to ask you, wanna send me the brackets for ya charger (my welder broke) LOL

best of luck with the build champ. i wanna see specifics on the charger and dyno results

[bardabe]

your an animal.

[redline racer510]

how bout having the best of both worlds and twincharging the ish*?

[OBEEWON]

Holy macaroni.

[gsracer]

all the bracketry and oil feed are done, intercooler is also mounted, tommorow intercooler piping, blow off valve and oil return.

pics of pulley and belt arangements

I saw that you're trying to figure out what the hell to do for a tune. I recently installed a Gen I AEM EMS in my miata that's making 18psi on a stock long block with a wipple. The price on the GenIs has dropped to around a grand for a brand new one since the GEN II just came out. It looks like all kinds of people are using the honda boxes on all kinds of custom projects (part number 1050 I think). This is possible because all of the sensor inputs are fully configureable. For example I'm using RC injectors, GM 3 bar, and a GM air intake temp sensor inplace of the mazda stuff. Just tell the ECU what to expect and you're all good. Plus the AEM has fun stuff like programable traction control, integral 2 step, and great logging software that is included at no extra cost. It would be some work, but it's an affordable solution.

damn too bad this wasnt ready for last weeks fun in the rain lol. that would have been sick to slide around the big loop.

[gsracer]

sicbastard i already ended up going with nistune, and ill be trying to fine tune myself, with help from a friend

todays work, intercooler done

[SicBastard]

IC routing looks f'n perfect.

[Sileighty_85]

Sick Build Brah.

How is the light output on those headlights?

[gsracer]

wooh, what a day. i cant tell you the countless hours i spent doing the simplest of tasks, 2.5hrs to do the oil feed line, due to the proximity of the headers, frame rail, crossmemeber, motormount and steering, it was a nightmare, i had to weld up a tool just to get the damn thing out. needless to say everything is done. The ecu should be here wendsday and all i really have left is hook up the blowoff valve.
on to the pics

3 inch intercooler piping FTW!!



Everything back together









Welded a bung to the timing chain tensioner window access point for oil return.



Back side of the supercharger





Some vids

First crank up of the engine with boost, untuned of course just idling

YouTube - Vortech supercharged Vh45de s14

Ofcourse i couldnt resist myself, plus i needed to see how much it was boosting, so i pulled about 8-9 degrees at the CAS, and bumped up the fuel pressure, no incar unfourtunatly but you get the idea

YouTube - vortech supercharde vh45de s14 first drive



Well since i pulled so much timing across the rpm band plus bumped up the fuel pressure, plus being untuned it pretty much ran like crap, very sluggish and bucking and hesistating, really bad that is up until about 5500rpm, then it screams, theres so much left in it ofcourse once the tuning is done, but i feel like its gonna be a monster, fwiw boost hit peak of 8-9 psi at 7000rpm, im gonna go one size down on the pulley for now.

Special thanks to Abe for helping, and steve for the tuning.

[xpertsnowcarver]

Hell yea, get a smaller pulley!! I wanna see it do AT LEAST 12psi

[gsracer]

i mean less boost lol, i think im gonna max the injectors at 8-9 psi

[Slammed Assassin]

damn this build is so sick!

[S13SILVIA|E46M3]

This car is KickAss. Makes me want a VH real Bad!

[2forty less]

sick cant wait to see it friday night

how are you going to squeeze an air filter in there? that looks awfully tight between the blower and core support

[sil80 monster]

sooo clean, i love it!!!!!

[bardabe]

real nice, lets see that Dyno Graph
