Good update man, thanks. What are you thinking of for getting air into ze motor? Looks like quite a bit of room to get some sort of cool air intake - they say on an N/A motor that type of thing is very important... It should suck air from a cool spot and not meet much resistance on it's way into the motor. That's what they say I think... :-)

Hey Mickey Mouse,

I've not given it much thought yet, I think for the 3rd of November I'll just chuck a pod filter on the end of the MAF sensor housing, so long as it runs! Once everything's running l'll go back over a few things and tidy it up.

So eventually a cool air intake in front of radiator perhaps? There's so much airflow under the bonnet that finding cold air probably isn't much of a problem!

I think the specs for the 350z said the factory airbox added 3hp in ram-air effect alone!

Yeah man fair enough eh. Good luck for the 3rd - it'll be hard yakka but good to have a deadline eh. Exthiting times.

Nah you prob don't need to go all the to the front of the radiator eh - should be plenty of cool air behind it - at least until you fit that carbon fibre undertray eh... :wink:

When you get your pod it's worth spending the extra on a K&N, you look at all the tests and the other brands will either flow poorly or let in heaps of crap - even the exxy Jap brands are no good.

You know your car will have around 300hp per tonne, should make it pretty quick - 0-100 in under 5 secs... Should be a bit of fun.

Fuck I can't imagine how fast 0-100 in 5 secs feels like! The fastest car I've owed is this one with the L24. Something tells me my wheel sizes wont support very good 0-100 times though, might need to go bigger.

The deadline is pretty tough, but I've been without the car long enough thou so having the deadline is great for motivation. And Pais is sweet with all the shed time if there's a deadline involved for some reason.

Might as well get a K&N one, they're not that expensive when you look at all the other crap I've bought.

Oh you mean wider rubber right? Not bigger wheels - yuck. Meh - it's only first gear wheelspin... More traction at launch just puts everything else under more stress.

You know once Pais has a ride in it, she'll be calling for a roll cage right?

One look at these calculations and you might be thinking about a cage yourself!

Yeah, wider, not bigger diameter. I can get wider tires on the current wheels, so will try that first.

My word, 4.1 seconds is madness. She's already very keen on a cage. I suppose it makes sense. I'd like to have a harness bar with it so I can run harnesses when I'm at the track. But my seats aren't designed to work with 'em so not sure what to do there, I quite like the look of the stock seats so don't wanna replace them. I've seen people cut holes in their seats to accept harnesses, might be the go if I get an upholsterer to do it...

Orrrrr replace them with some classic racing seats if I absolutely have to.

Phew. Glad that's what you meant. Methinks the arches will be too tight right? Hmmm dunno how it would look with wider tyres - not the same!

Yeah no point in a cage without harnesses - you don't want to be bouncing around in there should the unthinkable happen.

You might have to man - your seats don't even have headrests right? Stock seats and no cage will be just fine for tootling about on the street tho aye.

Will the engine be ok oil wise on ze track?

There's actually a fair bit of room in the arches for tires, I can definitely go wider. Dont wanna go mega balloon spec thou.

I may have to just get racing seat. But if I do I'll get something classic looking. This is the stock seat with 4pt harness but without holes for top straps:

This is one in WGTN with holes cut somehow:

edit: yeah the engine should be OK oil wise at track. 350z's don't seem to have any issues.

Yeah side bolstering would be nice actually... You do slide around on those seats. A race seat really would be better.

I just don't like the look of 240's with race seats and roll cages. Prefer it looking more street.

Hmmm.

Anyhoo, I'm probably getting ahead of myself. ho ho

Both myself and zep got ahead of ourselves when doing our engine conversions/builds. He ended up with race seats and a half cage, I ended up with a stripped car and race seats. All when the original idea was just to give the cars a bit more power. Don't lose track of your original goal just because it's going to potentially be a fast car. You want it to primarily be a cruiser and occasional track toy, not the other way around. An old car is never going to be the safest thing around, but that's not what they are about. Plus people still manage to kill themselves in new cars with 5 star ancap ratings, so providing you drive with care and don't get too carried away when not on the race track the engine isn't going to put you anymore at risk.

TL:DR - just slap the engine in and go hooning as is

You're totally right. I really want it to be a old japanese street car, which is a bit of a giggle at the track. Definitely don't want it to become awkward and too track oriented / uncomfortable.

I'll just stick with standard seats/belts. Half cage is still a possibility later on. But I'll go hooning first!

True dat. Harnesses definitely cross a line.

One of them removable half cages might be a good compromise - to keep pais happy. :-)
