Congrats on the magazine coverage. Well deserved.

I love this car so much! Thanks for bringing it back with so much awesome!

Congrats Doc, i'm loving it.

True hotness brotha...

9th picture down is now my desktop pic. That is what the inside of a car should look like. Well, the whole damn thing is freakin' beautiful. Very inspirational. Thank you.

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.

Quote:

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.

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.

Looks like a really interesting project. Good luck with it,

I would do gloss black (murder to keep clean) but would make all of those pretty parts pop even more. Chip Foose uses this method on almost all of his designs and I love it.

Gearshifter braket needs goood 4-5" of cutting to come in place of stock hole as well.

Crossmember is touching the crank case but will move the engine down another 3-4". Will alter the cross member might make a new one and move the radiator close to engine along with AC condenser and Oil cooler. Intercooler will be in same place as before might be longer pipes but wont be close to hot oil cooler.

Parts already ordered will be here in a week's time
1. Griffin Double Pass Radaitor 19" X 24"
2. 16" Flex-a-Lite high majic 3300 CFM puller fan with shroud would need some shroud work, going with single big fan then twins as last time.
3. JWT clutch and flywheel combo
4. Moshimoto Intercooler
5. Moshimoto Coolant reserviour tank

Also converting to power steering as feeling wise stock wasnt that good and crossmember is in works so would be easier to do now. so got these
1. Used 2000 Subaru forester steering rack
2. New outer tie rod ends for 1998 subaru legacy/impreza
3. 84 toyota celica inner tie rod ends
4. Whiteline steering rach & Pinion mount bushes
5. Energy suspension stock steering rack bushes
6. Moshimoto Power steering bottle ;)

There is a DIY to install subaru forester steering rack using celica inner and legacy outer tie rod ends, lets see how it goes.
