VH45 s14 S/C

Man I just read through your entire thread on zilvia and on here. I have to say that this is the greatest build thread ever! VH45 is certainly going to be the new bandwagon with builds like this.I need to scrape up the engines fast!

I've got some spare phase 2 injectors if you need them...

Thanks. I have to find out which one(s), if any, need replacing. I did a quick consult troubleshoot turning off injectors and couldn't find any one that changed more than the others. I wish whatever it is would just break so I could find it....just not in the middle of nowhere please. lol

let your car idle for a bit then just pull your plugs and see which one has fuel on it or smell the tips then you will be able to find it! alot easier than pulling everything down untill you absolutely have to!

Post by **tmorgan4** » Sun Nov 01, 2009 8:52 pm

I'm not sure if your cars are set up like mine but it's a huge pain to pull the plugs!!!

passenger bank in my vh s13 wasnt too bad to get to...drivers bank however brake master and booster had to come out for sure.

thats wierd, i can remove all my coils and spark plugs with out removing anything..

Post by **Carl H** » Mon Nov 02, 2009 10:55 am

probably has to do with mounting, my engine was mounted level with the xmember while i think the mazworx kit places it lower than the xmember...correct?

Don't really know how the engine can be lower than the crossmember?

Good point, bit of a brain fart there...

Yeah that could do it. FWIW, I can chance my plugs with the booster in as well, on both the S14 and the Z32.

Me too.. just takes some creativity with the order you put the socket on, extension, and eventually the ratchet. But it's not that bad. Takes some finagling.

Thanks for the help guys. Haven't been home in about 3 weeks, been working. Also getting ready to move to Houston in a week or two. One of these days I'll get some time, parts, tools and a place to dig into it. I just know something isn't right.

The first VH I had in there was like butter smooth. Typical with the VH, you couldn't feel a thing inside the car. But this one has a vibration that is consistent with rpms, unfelt at idle and WOT and seems to richen up the fuel from time to time. I ran BG44K through it first miles and the idle would creep up every so often, telling me they were dirty. It finally leveled off and was good from there out. Ran the piss out of it racing a SRT-8 and the idle jumped up 500 or so and hasn't come back down, exh smells much richer than before, especially in the morning.

I may just get an entire set from Deatch and be done with it. I'm the kind of guy that will replace any part that is believed to be less than normal. If I have one injector clogged/bad, the rest are sure to follow eventually. Just sucks they are so damn expensive new...

You are my hero...I have been eyeballing the superchargers for the mustangs for sometime and now here it is. Attached! Thank you thank you thank you...Now I know what I have to do for the Z45.

just out of curiousity what rear end are you running....been following this pretty closely as im hoping to put together a similar setup in a new project...

Jerry has the J30 read (3.96:1) right now, but last I spoke to him he was considering the G50 Q rear (3.54:1)

thats freaking awesome!!!

Post by **T45** » Tue Nov 17, 2009 10:33 pm

His 450 could use a TTZ or Q rear end, the blower just melts those 315 rears, I would say through 50-60 mph easily. lol

that should help the top end...

q45 is the way to go TT rear is more involved than the q45[diff,z and q45 axles,,new driveshaft or flange]

Post by **Steve Lloyd** » Thu Dec 17, 2009 11:52 am

Q45 and TT rear ends are the same, unless you are talking a 97-01 Q45, then you still need J30 axles.

Post by **Loch Ness** » Thu Dec 17, 2009 12:06 pm

the rear cover bolts are different

u do realize that the diff is kinda offset

No, they are NOT the same. Please stop spreading misinformation.

Q45 90-96 is an R200V 3.54:1 with 6-Bolt high spline count output flanges and a large 4 bolt input flange. It is a BOLT IN upgrade for S chassis cars when using one Q axle, one Z axle, and TT hubs. It is stronger than any stock s chassis/J30/Z32NA rear.

Q45 97-01 is an R200V 3.69:1 with 5-bolt low spline count output flanges (came as stock S chassis) and large 4 bolt input flange. It is also a BOLT IN upgrade for S chassis cars. It is no stronger than any s chassis/J30/Z32NA rear but it has a taller ratio that is the same as Z32TT.

Z32TT is an R230 3.69:1 that is much larger than the R200. It physically does NOT bolt into an S-chassis car. The output flanges are the same bolt pattern as the 90-96 Q, but the input flange is a 6-bolt CV style joint.

gs14 - Any upcomming plans to upgrade the fuel system? I'd imagine your OEM injectors are near 100% duty cycle at that HP & lambda.

I had trouble finding aftermarket side-feed injectors that would flow the amount of fuel I desired, so I ended up fabricating a new intake manifold that would support top-feed injectors.... It was a PITA because the manifold project was the first time I ever welded aluminum and had to learn along the way. Fortunately, I could probably make another (better) one in 1/4 of the time now.

Are you running an aftermarket fuel pressure regulator? It would require some ingenuity to adapt, however it would probably be an inexpensive and much simpler method of increasing the engine fueling. Raising the base pressure from 43 psi to 65 psi would give you a 23% flow increase, which may be good for another 1-2 psi of boost.

Great looking setup!

Wouldn't one of the Nissan aftermarket adjustable regulators work just fine? I'm using a factory fuel pressure regulator off of a VQ30. The one that came with my engine was completely plugged and the performance shop across the street dug up an old one off a VQ that was identical (on the outside, anyway!!!).

Post by **Jeff Taylor** » Sun Dec 27, 2009 5:50 pm

Yeah, true.

Well i am already running 65 psi rail pressure and i see 100% duty cycle in the upper rpm ranges, i am running the timing a slight bit conservative on the top end will pretty much after 5500 rpm.

As for the aftermarket regulator, any nismo adjustable regualtor such as those for s13 sr20dets, the most common one available, bolts right on to the vh fuel rail with just a little rerouting of the stock return line.

As for upgrades, ive already confirmed that nismo/tomei as well as subaru injectors fit into the vh45 series 2 rail with no modifacations. Now that christmas has past i will have a little more money to spend on the car and will be upgrading to 750cc injectors and an external fuel pump with -8 feed lines and will be dual feeding the rail as well.

The maf is also slated to be upgraded to a ford lightning unit as at 6500 rpm it pegs 5.114 volts. So after all this is said and done ill be uping the boost a bit.

Great to hear. Will the series 2 fuel rail bolt to any VH45 ?
