180sx Vh45

[GTRsean]

Those crank pulleys are done up real tight for a good reason. The oil pump is chain driven from the crank, but the sprocket on the crank is not keyed like the timing chain sprockets. Make use torque it up to the recommended values. I think it's about 270 ft/lb. Apparently it can cause issues if it' done up too tight too, have a search on NICO, heaps of info there.

No probs. Thanks for the info, I'll have to check.

I learned that the hard way on my 26, chewed the crank keyway and key out due to bolt coming loose (not enough ftlbs=350).

Even more so with this setup then, otherwise no oil pressure?!?

[Chrispy]

Yep, too loose = no oil pressure and a spun bearing VERY quickly.

[GTRsean]

PICS= interesting topic lol.

It's fun spending other people's money!!

First up brand new os gikken competition twin plate, with sprung center. I was going to use and exeedy type flywheel and clutch as we have a near new one on hand but the owner wanted fresh tougher stuff!

5 Stud conversion kit. Got this because, the choice of wheels opens right up, and fitting bigger brakes and discs from the skylines is a lot easier to do. I redrilled the previous 5 stud discs to 4 stud, now it's bolt straight on! Pull the dust cap, remove the split pin and get a 30mm socket on the nut. Spindle just slides off, too easy! New 5 stud spindle on, with a new split pin, dust cap on, disk on and bolt the caliper on.

Just need some s14 5 stud rear discs because silvias/180's don't have drum type hand brakes like the skylines.

Just the rears to do later. Just 4 bolts at the back of the hub assy to undo, instead of 4 bolts with a big nut like the skylines. My GTR 16's fitted to the front, and front guards are going to go back to stock as per owners request.

[GTRsean]

Got more stuff back now. Water pump and gearbox bellhousing, adapter plate and fasteners.

Adapter plate fits sweet, and no need to space the flywheel etc.

Clean gears!, and spigot bearing fitted after pulling out auto bushing.

Adapter plate fitted to back of block.

Adapter plate bolted in and flywheel fitted.

Clutch installed and clearance around starter hole.

Bell housing test fitted after grinding bumps off inside of bellhousing to clear ring gear, starter bolted on with spacer plate.

A spacer plate for the starter motor was needed as we used a turbo flywheel, which is bigger in diameter than a non turbo flywheel.

[GTRsean]

Bolted up gearbox after fitting new input shaft seal etc.

Here's the auto trans crank bushing, also had to chop a bit off the end of the input shaft due to machining of bellhousing.

Test fitting of engine and gbox, and view of the eng mounts. Still have to weld in the rest of the mounts.

Under the car....

Neat fit!!. Also have to get a smaller brake booster to clear the cam cover.

The clutch cylinder is hitting on the cam cover so it'll have to be moved up.

You can see how far forward the eng mount is compared to the crossmember mount.

Once a booster and flare spanners are purchased more stuff will get done.

[GTRsean]

To sort out the engine mount misalignment, went and got an R32 front crossmember to line up the mounts better.

Yet to switch em but it looks like it'll do the trick.

[Chrispy]

Good stuff! I'm digging those UAS engine mounts, I might change mine to those too...

And a Pulsar brake booster might fit. You're running close with the clutch master too

Have fun making the extractors

[GTRsean]

Thanks Chris, the mounts are pretty rigid, the engine didn't move when I removed the eng crane!

Well here's what was done most of this weekend:

Removed CA18 crossmember, and fitted RB20 crossmember, now the power steering lines are out of whack.

Engine mounting points now line up, moved engine forward a bit to suit, now the shifter will fit through stock hole as well.

Changed the clutch master cylinder, brake booster and cylinder for more compact items, clutch master is R31, booster and master cylinder is an r33 non abs one.

Fitted new chain guides, oil seal, water pump etc.

Measured up and centered engine and gbox for mounts to be made up. Cut up the steel plate to required shapes for each side and Mig welded them up, then painted. Mounted to engine urethane mounts then, bolted them to engine and crossmember.

A side bonus for me was when I crawled under to size up the gbox xmember, I thought I'd try the stock CA18 manual original xmember for fitment, the bloody thing bolted straight on the chassis, and lined up with the VG30 gearbox perfectly!!

Pics:

Extractors I won't have time to do as I have to head overseas soon, so the owner aka Farch will have to sort it! Check these collectors out though, I told him to get these! work of art!!

[boxheadmr]

Looks like a great build, what is the weight of the VH45 compared to the SR20 ?

[GTRsean]

Roughly 20kg more than the SR20DET setup (intercooler, turbo, piping etc). So it's not bad.

Engineer came around to inspect the car and he was very happy with everything so far.

Gearshifter is in and tailshaft is in. Pics to come soon, once the extrac-tam-mators are in lol.

Farch can't wait to drive it lol!! Still a bit to do.

[Sanouske]

As soon as i saw the vh45 in print i just had to have a look. Seems they fit reasonably well in these vehicles compared to the 300zxs seen in another forum. Bonnet bulge much Chrispy =P

Love the engine bay of that canadian drifter. Fine work with the intake pipes.

[BezerkR32]

this is a conversion close to my heart.....great work guys. it will be well worth it. trust me.

[GTRsean]

Exhaust is done, twin 2.5inch into a single 3inch, with twin cats, 4 into 1 headers.

Finished the main wiring to get the engine running, had to cross check the 180sx and vh45 wiring codes and fix a couple of wires, so now it starts and runs. Sounds sweet!!! I'll put up a link to youtube soon.

Also fitted the alternator and made some brackets to attach to the block. There is clearance!

[GTRsean]

Youtube link for vid.

[GTRsean]

Finished the cooling system by cutting radiator hoses to fit the outlets on the block and radiator. Also got a belt that fits the alternator, just needs thermo fans. Adjusted clutch pedal and took it for a quick spin with no brakes or seats!

Just the handbrake to pull it up. It sounds tough and goes hard, and no traction lol.

Putting up more youtube vids.

[GTRsean]

The instrument cluster needs to be sorted too. Tacho needs to be recalibrated for the v8 signal, and the speedo also needs to be adjusted.

[GTS_Kid]

basically it started when i got my ca tuned again and it got 225kw and on the way home started making tapping nosies at part throttle and lost power, when i got home an hour later it looking like i had done a main bearing. after riding around in GTRseans R32 all of these years i was getting sick of torque of the ca, as a joke i said "why don't i just put a v8 in it." and sean sugested that he's up for a challenge and if i organised the engine and equipment he would help me with the making of engine mounts and all the unforseen things. after a few visits to MRC who is putting a twin turbo VH45 in his R31 and lucky enough had a stock vh45 and auto gear box that had just been put in a 300zx, and doing a few measurements to make sure we fit between the rails i had an engine and gearbox sitting in my garage and a ca18det with no where to go (ps pulling apart and selling)

the following pictures are of sean and me test fitting the v8. we are currently ( by we i mean sean) trying to complete the custom bell housing to suit the 300zx manual gearbox i bought for it.

niccce!

[GTRsean]

Farch might actually post something about his car one day!, instead of me.lol.

[farch]

thought I'd comment on my own car lol. I'm very impressed at how responsive the engine is, can't wait drive it somewhere other than the driveway.

[farch]

Farch might actually post something about his car one day!, instead of me.lol.

lol, very funny...... hey wait why I'm i talking you on the forum when you live next door?
