Lots of work has been done, changed the brake booster, custom fitted one from some Mitsubishi pickup, fitted nicely on 1" willwood brake master cylinder. Sorted out the gear mounts and downpipe, some dropping in the front on right side it bottom out already seems like fenders flares might not be installed properly or some other issue.

 

Installed custom door sills

Some work done in past few weeks

 

Changed the coils, plugs (thought plugs were changed in previous workshop), installed GPS module for the autometer speedo as had problem in getting signal from the gearbox and also installed the autometer fuel center unit.

 

Plugs, no idea how the car was running and even tuned on these, I did ask the workshop when installing other things to change it got back to them and they said politely ohh we forgot

Nice photos, I like the ones with the Burj Khalifa in the background. I spent 5 months in Abu Dhabi in winter last year, had a great time, gutted I didn't get to go back this year. I lived at the Yas Marina Cicuit and loved all the car action, F1, drag racing, drivng on the F1 track in a few different cars, drifting in one of the big car parks outside the track, not to mention all the nice cars you see in Dubai.

Ok project moving in another phase Engine SWAP. As people on some forums know I sold my current setup with everything including radiator, ecu etc.
 
I was planning for a while to swap RB25/30 NA setup but after reviewing it a lot  working with different heads and lack of upgraded cams in some heads dropped the idea. Moved to VQ35DE/HR for which wiring is a bit of a pain but then couldnt find HR engine and where I found with online wiring service (2k$) and engine cost over all project costs jumped.
 
So in between talking to few installer came across something unusual and interesting taking it as a challenge.
 
VQ30DET, its a rare engine same quad cams but block is much stronger then VQ35 and low compression as it comes with a turbo from factory. 
 

 

The 3.0 L (2,987 cc) VQ30DET is a turbocharged version of the VQ30DE. Bore and stroke remain the same at 93 mm and 73.3 mm respectively, and it has a compression ratio of 9.0:1. It produces 270 PS (200 kW; 270 hp) and 271 lb·ft (367 N·m). From 1998 onwards, it produces 280 PS (210 kW; 280 hp) @6000 rpm and 285 lb·ft (386 N·m) @3600 rpm.
It is fitted to the following vehicles:
1995–2004 Nissan Gloria Y33,Y34
1995–2004 Nissan Cedric Y33,Y34
1997–1999 Nissan Leopard Y33
2001–present Nissan Cima F50
 
As per some forums stock engine is running on 5-6psi and gives around 280hp and turbo can go easily upto 14psi before playing with the wastegate and power can go upto 350ish but still needs to be checked, as people are running cars upto 500whp on stock block and its holding great so there is good potential in the engine. Being a destroked version compared to VQ35 its revs better as well. One other things which my mechanic said engine is without VVT so can change the cam gears as well if needed along with cams maybe for future.
 
After looking for a while found one here, as per Air flow meter clips seems like came out of 2002-2006 model Nissan Cima here it is

Bought the whole things with 8 speed CVT gearbox lol, and engine mounts sway bars and most importantly ECU and harness.
 
Was lucky found a CD009 gearbox out of 2006 JDM 350z as well.

Covers removed from engine

img2013051501654.jpg
 
There will be alteration needed in cross member, whole exhaust manifold on engine and might need to move the turbo a bit as well.
 
I opened up the engine so do some colours and for some porting the exhaust and intake inlets, engine was clean but too much slug inthe oil sump seems like car was running on those 30k limited oil, but compression came out good. Only problem was turbo came out broken one fan was missing so will change that from the shop got the engine. 
 
Fan was chocked and one side one is missing, as for the size seems bigger then RB25 turbo more like GT25 series size.

Will be installed once engine is all cleaned up

 

Removed the old engine and engine bay came out messy, thinking of painting a satin black or sating finish golden while its empty, any suggestions?

Engine mounts are in works, which is the tricky part will update how it goes.
