Hi all, i have a p10 SR20DE i use for club racing and its time to upgrade to a LSD box, but i want to go to the later P11 style box or VE box so...
1 I read somewhere SR16VE boxes have a 4.4:1 diff, this is much more useful to me so does anyone have any gear ratio info on 20VE and 20VE 6 speed boxes ?
Do the 6 speed boxes have good useable ratio's?
2 Are the gearsets as strong 16VE vs 20VE ?
3 Apart from axles to suit and switching to Hydraulic master cyl or converting box to cable are there any other issues to watch?
Also i plan to do a motor a little down the track and the options i have thought of are
1 Retain the std SR20DE, freshen it up and do cams, valve springs, cam gears, and skim the head for a bit more comp, maybe pistons.
2 Buy a (cheap) GTI-R motor and de turbo it, retain the quad TB's, freshen it up, new pistons to bring the compression up to 11:1 or there abouts. as well as cams springs and gears.
3 Buy a later (p12) SR20VE and 6sp package and use this for a start and do cams etc as budger allows
I will use an aftermarket ECU for any upgrade.
I heard the turbo motors have bigger ports but do they have bigger valves ? and are the quad TB's a good improvement for the NA motor ?
Im looking for a good power increase without spending mega money and not going turbo (it would move me up 2 classes in the racing and huge budgets, huge power are required to be compeditive in this class!) Im a mechanic so that side of things is not an issue.
I am not sure what you are saying, but you should go with the sr20ve with 8cw crank. The sr20de will never make the power of the VE and will cost more to try.

Right-o, since no one answered i spent the better part of 15 hours looking on the net and making phone calls.
I have the choice of a 16VE or 20VE motor and I will use the 16VE 5 sp box as i found the 6sp ratios which are basicly the same 1-3 with higher 4-6 which is no use to me.
I intend to use all stock Nissan parts except rings, bearings, rod bolts and gaskets
So what i am thinking is:
Block: 97 on JDM SR20DE with full cradle, oil squirters installed, redrilled for vvc oil passage.
Crank: as above 4 counter weight
Rods: Unsure here, are turbo ones worth it for the extra weight? if i get the 20VE i will probably use these rods, if not then SR20DE JDM ones will do, i have never herd of a SR rod failing any way. Will fit new ARB bolts though!
Pistons: SR16VE notched to clear sqirters.
Head: Now this is where the decision on the donor motor is critical, I realise the 16VE combustion chamber is smaller and the compression is right up, but haven't found any comparison on port or valve size as of yet. Also is it worthwhile getting a stud kit or are new head bolts more than adaquate? I may do some light tidying of the ports, but nothing major.
Cams: SR16VE. Should i upgrade the valve springs? Will i need Adj pulleys to correct cam timing?
Oil pump: VE from which ever donor motor.
Sump JDM SR20DE, slight increase in pan size with better baffeling around pickup (have oil cooler too)
Intake: Stock manifold to start with, but change to black top 20V 4A-GE (45mm) quad throttle bodys later.
Exhaust: Custom 1 7/8 4-1 headers into 2.5 inch system (I have mounted a new radiator where the A/C was, heaps of room for nice long pipes)
Clutch and flywheel: Current SR20DE high port lightened flywheel and button clutch.
Gearbox: SR16VE LSD box, may look at phantom grip if not tight enough!
Management: Microtech efi ECU, Taylor leads and Bosch coils
Does any one have anything to add, any problems or better suggestions ?
Pretty new to the VE motors, so help is appreciated
why would you go to the time and expense of installing the oil squirters and redrilling the block when you will already have a perfectly good block to start with?
you will have to use genuine nissan rings as they are different from other de rings and nobody in nz has them aftermarket.
if you want power and reliabilty for racing, use the 8cw crank and cradle and the de rods.
there are already a lot of built ve motors in nz , and some of them are used for racing and/or track days with good success, the sr16 and p11 box's are strong and dont seem to give many problems.
what class of racing are you doing and where do you race.
