since Im not doing anything yet, i dont have anything to contribute. Once we get some more people involved, i'll sticky it!

So lets hear these sexy VH's setups!!!

S14 (late) 240SX Chassis

Late (94) VH45DE with built bottom end (Ross/Manley/ARP) and stock heads/cams (GTIR Valvesprings will be the only definite change with the possibility of SS valves)
Custom intake manifold
Twin Turbo, GT35Rs
Engine management is up in the air right now, trying to learn all options before deciding.

BRETT Engineering GM T400 transmission adaptor kit
JW Trans and custom converter
Specialty-Z TT Flexplate (ring gear flipped to work with stock starter)

Modified rear IRS (DSS axles, SPL arms, HKS Drag suspension) I would like to backhalf the car and use a 9-inch, but NHRA Sport Compact ET Bracket rules will not allow it. If the car keeps busting up pumpkins I'll go solid axle and just run the domestic events.

I'm also trying to put together a 92 VH with stock rods and ross pistons for SC'd duty in a Z32. That's down the road though, the dedicated track car is first.

EDIT: sold truck, scored 90 300zx. vh, z32 na 5 speed, na rear end

Since you're going for drag racing you may consider swapping the Q45 differential in. Its an R200 as well but uses the same axles as the 300ZX TT, which are huge. Plus its a lower ratio, which with the turbo setup, should make you faster on the strip. If the diff itself has a hard time staying together you may considering trying to fit the TT differential, which is an R230. Translation... its slightly bigger than the Ford 9 inch

I can't remember if the subframes are different or just the arms. I know at the very least, the subframe design between the 240 and 300 are very, very similar, which would make it easier for the differential swaps.

I was unaware that the Q45 diff was an R200, I thought it was an R230 just like the TT-Z. I'm not terribly concerned with the axle size since Driveshaft Shop will be making me some axles that I shouldn't be able to break. The center section, as you mentioned, is my big concern.

A Z32 subframe is wider than an S14 subframe. The control arms are interchangeable, but the frame itself isn't. I'm sure if I bought a TT-Z subframe I could get creative and make the R230 work in the S14 subframe... we'll see.

I honestly don't want any ratio taller than the stock 4.083. With the TH400 gearing and the 28" slicks I'll be running, I'll be at 163MPH at 8000RPM in 3rd gear, which is exactly where I want to be. My goal is to build a reliable, consistent, low-9 second ET Bracket car.

nothing has happened on it forever

nissan s12 silvia/gazelle
vh45de rebuilt 10.0:1
slightly modified heads
balanced motor, studs
gt42rs 102 mm comp
motec m800, sard 850 cc injectors
2 speed powerglide

thats essentially it

Any idea the spline count on those axles?

Ahh, yeah... I seemed to space out the bracket racing part of it. :lol:

I believe 32 spline.

lol, no problem. Actually, your input prompted me to look into an R230 rear as an option, and apparently Full Race has done one in an S14 already. Their car has a 2JZ which necessitates the extra strength...

R230 rear in an S14

That may work out for what you want.

Excellent, thanks! I will definately keep that in mind.

Now I just need to find some SR20 inner valvesprings... (hint hint guys)

Was that a hint that the SR20DE heads are closer to the VH45DE than once thought? Or just that the springs are a good match?

There is a thread in this forum about using the GTi-R inner valvesprings with the stock outter springs to help with increasing the rev limit slightly and increasing seat pressure. They are a nearly direct drop-in to the VH, but no, that does not mean the heads are anywhere near close. I have seem both heads first hand and they are very different.

and the next project that we are sizing up, vh45de in 87 300zx. possibly turboed.

Long wait.... stupid old workshop

1989 Nissan 240 Fastback
Pulse converter single turbo manifold.
Cunningham Rods & Wiseco pistons.
ITB's
Dry sump & Vacuum pump
Skyline GTR 5 speed

1986 Nissan HR31 Skyline GTS-X coupe, fully optioned, with JDM FGY32 Cima VH41DE V8
Manual conversion, custom 4-1 headers, dual exhaust system, freed up intake, retuned ECU etc.

I'm ***king happy to have it going now, it drives so damn smooth and has power at all RPM in all gears, it's a wicked street car.

Future mods include replacing the engine with a professionally built (by a stockcar engine builder) VH41DE with VH45DE internals, light headwork, insane cams, and GTI-R inner valve springs... setup will be good for 450HP and an 8000rpm limiter. Will post up some pics & vids sometime.

Oddly enough I was going to use susuki hayabusa bodies before I had the custom ones done.
There will be 4 complete sets already spaced out to suit the VH45 port spacing on ebay soon! Even got the correct susuki coupling pipes and modded to fut standard bosch injectors.

same project heres. except difference car body. let me know your progress.

I can share my problems with you if you want for the front midship .

Sure. I'll get back to you in a week or so.

KA-T why settle for anything less?

definitely none of those statements are true.

if i remember correctly, superhatch is using the adapter to mate an RE4R03A trans bellhousing to a T400 trans.

Sean's motor has cast iron manifolds because it is a VH41DE...

The brake booster however, needs to be swapped out for an 80s Pulsar booster. I just found one recently, it appears to be a small enough diameter not to interfere with the head, but still long enough to drive the brake master cylinder sufficiently. I'll put pics up when I can be bothered.
