in your n/a as in n/a what. . rb25?? alloytec??

Does anybody know what a stock vz (or with min mods like exhaust, cai) will do down the quarter. .

I know my old vl, stock RB30E did a 15.9. .

Im guessing a vz will do a high 14- mid 15

I've been hearing good things with turbos on the VZ engine, apparently they're pretty good when the compression is dropped.

The alloytec motor is the same as saab uses in the 93 aero...V6 turbo. The saab version is an awesome motor.

lol i hit redline at like 70/80ks in my 33, with turbo box. was an NA, but not anymore....

lol mine still na im going to do the turbo conversion..my gearings a bit tall so it takes a long time for my car to wind up

When I went to the drags with my friend (who owns a VZ SV6 = alloytec 195 3.6lt) he ran a 15.9 but the biggest let down with those cars is the clutch it slips far to easy. He had a bit of an exhaust upgrade but not much. If they had a decent clutch, light flywheel, zorst and short diff ratio (3.7 - 4.11) they would reel off a low - mid 15 down the quarter.

The best I've got out of RB30DE so far is 15.5 @ 91mph, but that was with a shit diff ratio (now have a 4.11 spool) so no traction over the 60ft with the single pegger and it was still rather warm, my motor should be good for a mid 14 as it sits.

I have both... a VZ storm with 3.6ltr Alloytech and an R31 with RB30DE.

Even on a basic running in tune the RB30DE is far more responsive and generally better all round than the Alloytech.

id have to disagree with you on that.. and yes i have owned both as well... the VZ pulled like no tomorow from 40ks onwards and was definately faster in a straight line race..

Maybe mines a dud...? Uses more fuel than a 5ltr Monaro,5.7ltr SS and 6.0ltr SS. Even Holden cant explain whyit uses so much fuel... They have tried tuning, injectors, FPR, sensors, the list goes on and on...

Doesnt matter how I drive, whether towing a trailer or completely empty I just cannot get fuel consumption down to reasonable level.

Mines is very flat off the line, pulls OK to about 110ish and falls over after that...

My RB30DE on the other hand...

Have you guys ever dragged a VZ Executive on a 3.08 diff, headers, hi-flows......... custom tuned (not by a tuner who just does it quickly in 1 day). They will eat a skyline for breakfast (if tweaked properly - not even near potential).

Your right alloytechs are good above 4k .......... tune them up (not avg tune).......... they flog a sv6.........

Mines strong off the line, once u get out of the 1600rpm (spark advance -1's) ....... (which I have for fuel econ) ......... the car plants into the road and takes off...... When I hit my 4000 range the torque jumps like 3-5% instantly on mine......... it's just like a turbo, suddenly engine free immediate pull even when going fast up the range.

I raced a few skylines, mostly N/A........ flog em everytime. One I come across was a R34T? ....... white, better looking them most, it had a mad exhaust, obviously all custom seemed like it was turbo......... he thought he'd be a smart arse........ so we didn't really drag, I just stayed in first gear and kept crusing up n then he decided to plant it......... second later I was gone....... smoked him. I think alot of skyline owners dont know about the above 4000rpm on alloytechs.

I respect skylines tho as u can do them up immensly....... but just like alot of commondore owners.......... they dont and hence they get wipped.

By now, most know the alloytech engine has been deemed a "torque monster".

PS. Funny thing with the turbo skyline i dragged, normally even tuned i thought it'd get me......... but that day i decided to adjust my ve tables, optimal engine torque and air demand for torque........... and pumped up my 4-6k rpm range......... and it seriously even stunned me how quickly i owned that guys face.

Alloytechs are very explosive, lots of fun tuning them............ as long as keep at it, u turn like a slug into a v8 effect off the line into a turbo feel above 4k rpm.

Personally I'm waiting for the SV6's to come out with direct injection.......... they'll be lots of fun in the coming years.

lol.

I have to agree tho, those sv6's are a good engine.

I raced one too ages ago - when i had a massive misfire issue. and we were pretty even but he slowly pulled away. However, I could hear him fully revving out 1st and 2nd, where as I didnt rev much(around 5-6k only)

Next day - took my car to soichi and found:

* crap plugs

* coils arcing

* timing retarded to 12 instead of 15!

* boost solenoid f**ked - causing massive creeps to 15psi.

Now, after new plugs, setting the timing, taping up the coils, and adding my MS-IBC ebc, the car was a different machine. It pulls harder then my mates 200rwkw 25t.

Now I just want another run with that sv6.

      S1 rb25/s14 starting problem

      By 25zenki · Posted

      Harness is for a s1 Rb25det, and it is engine and lower harness.  the old harness had broken off plugs and was in very rough condition/exposed wires and splices etc. it is not able to be put back on the car, I could visually inspect to see if they had rewired any pins on the ecu plug. The fuel pump definitly isn’t turning off it’s an external pump and very loud you can hear it. Will look at the other harness tonight, am also going to pull the fuel rail and watch the injectors spray, will update here with what I find. Pretty sure at this point it has to be something to do with injectors because car will fire up on starting fluid and cas is clicking the Injectors. Fuel pressure is steady 43psi

      Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom

      By 25zenki · Posted

      I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off.

      I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell.
