The bottom end handling 1000hp is 1 out of 20,000 VH45's. I havent seen a dyno chart either. I'd build it and get that out of the way.
Taking chances like that doesnt make sense for what you're already prepared to do.

After having seen Nyloc's post regarding the Nizpro speedboat having all custom internals, I'd definitely consider using H beam rods & forged pistons for durability... a Nico member originally posted that he'd been in contact with the guys at Nizpro and said that they'd left the engine stock in their original build.I'm not so sure now how much credence we can lend this information until it has been confirmed as fact or bullsh1t.

Hi folks  Major update on the project front. The S15 has now been stripped back to a bare chassis and sent to RS Fabrications in banbury to have all the preperation and fabrication sorted. I dropped the engine off this very morning so they can mock everything up and test fit it in the car. I have ended up going with a VH45 engine with Z32 gearbox, flywheel and clutch with a custom one off bell housing. See the pics 
As you can see, the majority of the original chassis holes have been sealed up and the entire floor pan has been seem welded. from the underneath. They have not done the strut towers as yet, but they should push on with that stuff as the cage goes in. The slight bit of damage at the front end has also been fixed, but i don't have any pictures as yet! Hopefully the next update will be pictures of the engine in the car for it's first test fit. Exciting.

| Quote, originally posted by Guishnu » | Hey there folks,
I have spent ALL day reading this section of the forum. You have no idea how hard it is to find information on the VH45DE engine. What a fantastic forum. Thanks! Anyways,
Im one of the drivers competing in the European Drift Series (D1 Great Britian) over here in the United Kingdom. For the last 2 years i have been running an S14 (with an S15 front end) with an HKS stroked SR22 DET engine. For next season (if i get my arse in gear), im hoping to build an S15 with a twin turbo VH45 engine. I seem to have the majority of the information for the build, the only issue i have at the moment is sourcing some stroger con rods and some stiffer valve springs. Any ideas? Are there aftermarket options available? As you folks seem to have a whole lot more experience than me on building and specing these engines. Would you mind giving me some feedback on my planed spec and letting me know what you think? VH45DE Engine (out of 92 Nissan Q45)
[list]
[*]Polished and finished head (looks pretty good as is)
[*]Re -profiled cams (256- in 256 out)
[*]After market or stiffer valve springs
[*]Ferriday copper (ringed) head gaskets
[*]Dished, forged pistons
[*]Aftermarket con rods
[*]New bearings, seals etc
[*]Custom- twin inlet plenums
[*]Twin VH45DE throttle bodies
[*]Twin SARD Fuel Rails
[*]SARD 850cc Injectors
[*]Custom exhaust manifolds (T25 flange)
[*]Twin Garrett GT2835R Turbo's
[*]HKS External wastegates with screamer pipes
[*]Exedy Twin Plate Clutch and Flywheel (Z32)
[*]Z32 Manual Gearbox (with adaptor plate and custom propshaft/gear linkage)
From what i have read, cooling could be a big issue with this engine. So i propose running:
[*] Twin Setrab 260mm oil coolers with Spal fans
[*] RB25DET (R33 Skyline) Koyo Alloy Radiator (with twin spal fans)
[*] Transmission cooler (another Setrab item)
[*] Fuel cooler (a mocal jobbie)
Any other ideas?
Not quite sure how to setup the intercooler etc. With two turbos and two plenums. Is it worth while using two intercoolers? Or am i just adding weight... Opinions? Fuel System:
[*] Twin bosch fuel pumps
[*] Forge Motorsport Twin swirl pots with
[*] Walbro Scavenger pumps
[*] Forge Motorsport Fuel Cell
[/list] Apart from the obvious engine mangement issue. Have i missed anything vital? Or does anybody have any feedback/input etc? Im shooting for 800whp with a 9.1 compression ratio. My theory is that if an SR canrun 400whp easily with a 9.1 compression rato at 1.2 bar of boost, then a VH should be able to do 800whp at well under 1.5 bar. Or am i living in la la land  If any of you are interested, here is a picture of my current car
 Thanks very much in advance!

Looks like your shop has some spiffy tools. What happens to your drift vehicles once you move on to a different car?

They get sold
The S14.5 in the picture there is for sale at the moment. It's got an HKS 2.2ltr stroked engine and some very funky turbo setup we developed here. Runs 380hp at 1.2 bar and around 450 - 470 when running 1.8 - 2.0 bar. Serious bit of kit! Used it as my competition and display car for 2006/2007 Shameless plug, but i will ship to the states Car advertised at £13,000 - which over there converts at around $25,000 thanks to the shocking exchange rates at the moment....

Hi Folks, sorry for the age between updates but I have a monster one here to keep you all satisfied!The most recent update:
Cage is in, chassis leg/front slam panel is fixed. The front and rear arch tubs are complete – all in all, it’s some of the best fabrication work I have ever seen. Pictures speak for themselves really...

And the one you have all been waiting for!
Engine and gearbox have been fitted into the chassis, cross member/cradle have all been fabricated, so this is how it stands as of today! As you can see, it’s been mounted as far back and as low as possible. I don’t know about you guys, but now the engine is in I get the feeling that this car is going to be very mean. It just looks almost evil sitting there. Weird. Cross Member Fabricated to take engine + more power
 Engine Mounted in Chassis (underside view)
 Gearbox
 Steering Rack Position
 Engine IN!
 Good fit, still loads of space around it
 Mean Shot
 Im a bit pleased…

Mean!!!! You certainly pulled all the stops on this one didn't you :pMy motor sits about as far back as yours, but it looks like you've got it sitting a little lower. Reckon you could take a pic from the side man? I'd be keen to see how low the gearbox and bellhousing hang as a result of the engine being so low. Oh... and check swaybar to front pulley clearance too, you may end up needing to go custom with the swaybar. Top notch, you should blow the competition away with your setup _b

Company is RS Fabrications if Banbury, UK. They do a lot of work for the ProDrive WRC Subaru's etc. They are a very serious company who spend a large chunk of there time building competitive GT cars. Seriously cool bunch of guys who REALLY know there stuff.

Without doubt... those are some extremely neat welds! These guys must dig your project to do such nice work on it!| Quote, originally posted by Guishnu » | | These pictures should answer all your questions buddy!!! |
Nice gearbox mount! If it's not too much trouble, can you take a side-on photo of the underside, lining the chassis rails up horizontally so I can see how low the bellhousing hangs relative to it?

with that mad nasty cage a strutbrace almost seems silly...
curious to know more about the adaptor plate, got any specs?
also i see that the xmember has been spaced down...i assume this is not only to lower the motor but correct the suspention geometry since the car will be nearly on the ground?

 It looks like you've got some serious fabricators on your hands. I'd guess some of those pieces were designed by an engineer.

Why, this is way too cool for a site like that? Man, that dude can weld some f-ing metal. Did you have the orange S14 with the exhaust canister coming out the quarter?
