Well this was my FI list
G35Driver - View Single Post - My FI List - tell me what you think :)

I now have an opportunity to get a used 100k 03 Vq35DE engine from a 350z
Blowing white smoke so needs some work but since im rebuilding i dont care!

I just need some help in knowing what to buy, I have pretty much spent the whole day researching and reading.

I am going to inspect the engine on friday to confirm no major damge to heads and cylinder and if not ill buy it. Here is what i currently have on the list to buy:


Wiseco Forged Pistons with wrist pins and locks 96.0mm (+0.020" Over Bore) 8.5:1 These ok? should i go for higher compression or what? Forged/non forged
Eagle H Beam Rods with ARP rod bolts
ACL Race Rod/Main/Thrust Washers & Washers
HKS Head Gasket or Cosworth Head Gaskets (i wont know what size until head has been machines) and is it true cosworth are rebadged comtec?
ARP L17 head studs or ARP L19 head studs. I will def not go over 600rwhp, can you buy used or new but opened L19s? i heard they break easy when used again or not stored correctly???
Rev up oil pump
Welsch plugs (need to be replaced when engine is acid bathed)

Brian Crower Valve Springs or Brian Crower Valve Springs and Retainers ?? Do i need to pay double to get springs with retainers ? for same price i can get s/c hand JWT ones

Machine work
Head recon
Bore and hone
Deck block
Compression test
Crack test
Balancing
Crank regrind

Questions:
1. Do i need any other gasket other than head gasket?
2. Do i need main studs or are the stock bolts ok?
3. Do i need to change water pump?
4. Do i need a bigger throttle body
5. Do i need new timing chains and tensioners ?

Is there anything else im missing?

I know ill need new clutch, throw out bearing + pilot bearing + ss line

But what about fuel, if you didnt read other thread then i got
600 DW injectors
300ltr DW pump

My aim is to have a really well build engine that i know can handle 550-600rwhp but that will only run at 450-500

Heat: What parts of the Turbo kit should i wrap? ceramic coat (engine builder said dont bother with ceramic, just wrap with DEI titanium wrap, from the bottle of intercooler to the turbo). ??

Am i missing anything?

Cheers guys :)

...it sounds like you're on the right track. Except, the title of the post is a fallacy; It's never 'done'.

lol i know its never done but it will be alot more long term!

So 8.5:1 is fine i have been told, and yes forged.
Cosworth are not rebadged Comtec but im going with HR OEM gaskets to try and save some $ to use in other areas, they are good for around 680HP i believe
Studs im still looking for L19 s/c hand, i think i found some so ill get them.

I will def get valve springs, not sure about retains, lifters or new valves, i guess it depends on the condition.

I will inspect the spark plug tubes, if no oil then valve cover gaskets should be fine. HKS come with manafold gaskets so i dont see what other gaskets i need, throttle body i will check.

Water pump will be replaced or rebuilt

Throttle body size is fine im told

and new timing chain and tensioners will be ordered

Still unsure about main studs vs using stock ones

ACL mains aren't that expensive.
I would stay away from used L19's. get new L19's or HR studs
HR gaskets need some grinding on the block but are a good option
HKS gaskets are proven
You will need a engine gasket rebuild kit
Replace the water pump
If paying for reco the heads then might as well get cams, retainers and springs

Thanks !
I will most likely get HR studs then and HR Gasket, the HKS Gasket and L19 studs together will be better but only if going over 600 and that wont happen and the price difference between the 2 is vast !

will get new water pump

hi R6n350GT
get " coolant bypass" instead of changing water pump
and dont buy hks/cosworth head gasket instead buy oem hr Nissan gasket rebuild kit
since hks/cosworth head gasket and oem head gasket r both 0.7 mm
good luck
