Shane's 260z to 400z Nissan V8 2+2

Taken from my intro thread:

8/3/11

Car is a 260z 2+2 1975

The car itself only has some rust in the front cross member, the rest of the body is straight. seems to be no rust in the floors or theres some bog on the car but havent played with that yet. It has a brand new bonnet and flutes, new panel under the windscreen. The engine is a holden 5lt V8 with aussie 4 speed that has a few goodies, 2x 45 webers, edelbrock manifold, oil cooler etc.

My dad bought this car a few years ago but never got a chance to do anything with it. I have just purchased it from him and plan to do somthing!

To start off with will sort out the body and get some paint on it, then start fidling with the rest to get it running.

decided the 308 will go,

i have a rb30e bottom end, and a complete rb25det. Could be looking at an RB30D w/ triple webers.

few pics from when it was bought home:

9/3/11

got a few pics of it before, slid it around on the dolley jacks and now ill be able to work on it.

Dummy fit up the front lip from my brothers Z (which he is on here too acdc-5, he has a black,caged, track spec 260z 2seater in the build) also the flares. i think he has a spare of the front lip so ill be using one, although i wont have the diffuser and the canards like this one does

18/3/11

Some more work tonight:

Pulled off the guards, bonnet, hatch, hung them up out of the way

Started to pull the engine out

all out.. took like 15mins hahah

Looking at the engine more and more and theres all sorts of bits on it, has pushrod guides on it, Exhaust sensors, big oil pump/filter/cooler, edelbrock torquer manifold, havent pulled the cam out but i'd be betting its aftermarket.

Heres a pic of the RB30e which has no head, bottom end is supposed to be all good. Also RB25DET which needs rings, so plan is to put the two together at least. The figure out how im going to do fuel

(can see the VH41 and my brothers Z here too  )

Looks like you have all the stuff there to do a RB30-25 DET. These are a pretty good engine and should yield some pretty good power, might need some chassis bracing if you go above 300HP though.

Looks like a good straight shell there, good place to start.

I've got shed envy.

Look forwards to seeing the build

Simon, you're not the only one.  I found myself looking past the car to take in the panoramic shed views ... and the 'borrowed' road signs 

trust you to notice them  :P. they are pretty cool signs at that

hahah yeah i love the shed

Some more work this arvo:

the car is completely stripped down now, the only stuff left on it is the crossmember/struts and rear subframe/struts + wheels to roll it around

now going to finish packing away all the stuff so i can put it back in its 'bay' and start prepping the car further.

oh and because i change my mind every day, the latest engine incarnation is RB30DETT. I have everything i need.....

looking good rb30dett crazy

whats the user name mean stance ae86 ?

His name is shane c... Dont remember what the 86 means though

I see you have a set of N1 exhaust manifolds for an rb26

Are you going to run an rb26 head on that now ??

I would stick with the rb25 as it has hydraulic lifters and is  a lot less hassle

I always thought the general consensus was that the solid lifters were better then hydraulic ones? Thought that was the reason why people chose the RB26 head over having to modify an RB25 head to solid lifters.

Sorry, just actually read your post (take foot out of mouth). Didn't read the "Lot less hassle" part.

Yes they are better if your going to track race your car etc.

Personally the amount of time people really track there car I dont see they are worth the hassle.

Modern hydraulic lifters dont pump up like the old holden days

Welcome back Waxhead. Long time no hear.

Thanks guys

just going to use the 25 head i have. My brother is using 26 head on his hence the reason i have the manifolds.

Although i keep looking at this damn VH41 to put in the Z 

Those flares look like they come from a kit, not ZG style flares. Are you still planning to use them?

go the vh.......

i got 3/4 the way there and stopped, went for the 34 neo 25,

still had alot of fab to do but didnt want to butcher the car too much,

now i have a 2nd 240, which will be butchered as its not fantastic to begin with.....

still goth the vh45 too, just sitting there teasing me also.....

I believe the neo 25 has smaller combustion chambers and so with the na 30 pistons will make a very nice street engine.

I am using an rb26 head on mine with the 30 na pistons and it gives it 8.2 its ok because it a 30 but 9.0 or closer would be awesome

what was that about changing my mind? oh yeah..

i now have a Y40 , from what i can see there is a couple of guys in australia with Y v8's but i think they were Y44? Eitherway i have both haha

fun fact i have in my collection right now: 2x E15ET, 2x RB20DET, RB25DET, 2x RB30E, RB30ET, Y40, VH41DE, 2x Y44, 2x VH45DE

Want to run the manifold sitting on it with the two webbers yummmm

Excellent. You have until Wednesday to get it running

daaaamn i better call Xzibit

If you go with fitting either y44 or y40 use set back plates as per jags that runs 350 chev install guide

When I fitted y44 to my car with angle modified std mounts to cross member mounts car was always a pig to understeer need that v8 as hard on the firewall as u can get it

And dont expect a power house unless u do some internal work

Mick

hey thanks for that, when searching on the net your car was basically one of 3 that was popping up.

Ive got the motor just sitting there on the mounts which the guy originally had the 308 sitting on, sits ok but i would like to get it further back like you say. Only thing visibly a problem would be fouling on the steering rack. Do you have any other pictures of your car, ive basically only got 1 or 2 pics i think.

Not expecting powerhouse at all, but the engine will definatly be re-opened. The motor was apparantly rebuilt but i have no idea to what spec so ill have to measure it all up. The ports have obvious porting/polishing. Probably will just get a freshen up, and maybe a regrind or 4.4 internals. Either way i hope the bonnet clearance is sufficient to run that manifold adaptor and the two side draught webbers i already have.

Have also seen someone running a GM HEI dizzy, ive got a dizy with points but no cap, havent attempted to find one not sure how hard it might be. Ive got a parts catalogue on the way (i have two H252 Presidents which are Y44E) so might be able to find a few parts with the connections i have at nissan.

Other than that i will have no problem making up exhaust manifolds or any other flanges etc as i have all the machinery on hand (CNC plasma etc.), Carby's will be easy, fuel pump is there.

Like i said i have a spare Y44E in the donor president although being injected only so many parts are going to work. I do need to find a balancer and work out the manual conversion.

I dont have a spare box for this (only on the donor president) and wasnt really intending to part the box as i wanted it as a spare for the complete president.

But from what i can find out the L series box bolts onto the auto bell housing.

Any other info you could help with would be awesome, i did notice you had a gasket set at one point, where did you source that?

Have loads of photos Happy to email some to u send me pm I ended up selling engine and most bits to guy in WA he mainly wanted it for extractors ,gasket set and the manual conversion i made up

Id be worried about your twin carby set up height wise as when i had mine i fitted 600 holley double pumper and before i fitted bug catcher i had to make aircleaner to fit under bonnet Holley fits straight over std manifold bolts just needs adaptor plate

Think i still have a dizzy cap and rotor button would have to check in my shed I ended up fitting pirranha electronic ignition to dizzy

I used celica 5 speed with the y44 auto bell housing left flex plate on and fitted 240z pressure plate and flywheel to v8 with hiace clutch plate Dont think l series box would fit from memory did look at it but that was over 20 years ago found celica better fit and it stood up to v8 good

I ended up taking fuel pump off and using holley blue Full Gaskets set i got from importer in melbourne but he has since closed

Let me know if u need and other info or help

Mick
