Ken's z31 I wanna go fast build

I am Ken from the Seattle area USA. I bought my 1985 300zx GLL non turbo 5 speed in 2011 with the impression it had blown head gaskets which only an RB  swap would remedy. I replaced the bad thermostat and drove it for 4 years.

Opportunities arose and I purchased a wrecked 87 300zx with what I assumed was a stock rb20 silver top and 5 speed swap for $800 usd. Car had been sitting for 6 years after the owner wrecked.

Engine was siezed so I started to take it apart. What I found blew me away. 

Internal:

.015" over custom Wiesco pistons

spool rods

full balanced rotating assembly oil snout to pressure plate 

spec stage 3 6 puck sprung clutch and flywheel 

acl bearings 

hks step 1 cams 264/264 

adjustable cam  gears and greddy timing belt

bolt on:

rc racing 750cc injectors 

precission 5557e dual ball bearing with billet wheel 

z32 maf 

aeromotive fpr 

Nistune type 2 board 

The list of parts well exceeded my $800 paid for the siezed block. 

I discovered the heard was ported by a hydroplane mechanic. 

I have no idea as to what power the car made or what psi the tune was done at. All the info I have is the car ran for two weeks and then it was totaled.

Welded in a nipple for the iacc and Aacv as well as a flange for the synapse engineering synchronic bov.

Also a 3 core s13 radiator modded to fit and a custom made shroud for the 14" fan. Unsure on cfm but the shop who built the car for the previous owner had used an oem vgz31 radiator and shroud with this fan tucked inside very crudely. Lower coolant hose is fitted with a temp switch for the fan relay.

Also when the previous owner of my 85 had taken the car in for diagnostic the brilliant mechanic decided to dump head gasket stop leak into the system and I did not want to chance the  heater core to fail and fill my fresh rb and radiator with stop leak. 

My Z has modded knuckles, running s13 Lcas and tie rods with the rack moved forward 25mm to prevent over centering. Of course I have no pictures of my own parts. S13 coil overs front and rear and s14 tension rods. Welded diff and poly bushings but one day will have s13 subframe.

I will attempt to snag some photos in the day light.

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
