Twin turbo 350z build.


TT350

Recommended Posts

All thats wrong with it is a loose manifold and a few age related bits and bobs that would be there, modified or not. 

 

I think anything like this is normal when it comes to modified cars. And lots of people do give up. I think about it too. 

 

But I feel that satisfaction comes from the long journey to realising a dream or goal. 

 

Not to mention it's my hobby as such. A hobby is an ongoing thing. 

 

Plus I really enjoy owning the car. It turns heads and sparks conversation with complete strangers. No other car I've owned has sprinkled little bits of those moments on the cake of ownership.

 

To be continued......

I quite often think of throwing the towel in when mine throws me problems all be it not that often Thankfully.  And I have done a couple of big Euro trips hassle free so it's fairly good for a modded car 

I've promised myself once I pay my morgatge down to a sensible amount I'll treat myself to somthing nice quick and just maintain it instead of spending time fault finding.

Untill then ill keep on modding :lol:

When it all comes together, it'll be good. 

 

I'm really looking forward to turning up the boost. It'll breathe new life into it. Literally lol.

 

380bhp right now so, 580bhp should be doable. I only gained 80bhp over standard when going turbo so 200 more bhp will be wild. At first.

 

Loose manifold is causing horrendous fuel economy. Just far too busy to fix it as it's my daily.

 

Thinking of getting a bigger FMIC and bonnet vents with enclosed air boxes directly the vents.

 

No doubt someone will be along to tell me why that will cause my car to explode though.

Is there no half sensible garages that you know off who could fit some gaskets, they dont have to be specialised, shouldnt  be a long job and would help no end :) Surely even a day on the bus to work has got to be worth it to sort that?

 

So what boost you running at the moment?

 

Are you suffering with high ait's to be thinking about a bigger fmic?

I think it's just because the manifold is buried so deep and the amount of guff on top of it. I'll have a trip to a few garages next weekend. The cost isn't even the issue, it's the down time. The garage I've been using is so slow. 

 

But yeah, will have a trip to a few garages next weekend. 

 

Yeah, the FMIC I've got that came with the kit isn't very big. Half of it is blocked by the oil cooler too. It does get very, VERY hot under the bonnet.

 

I heard of this zircotec coating that vastly reduces heat escaping the manifolds, etc, by a fair bit. That'll be worth looking into.

Get the torque app for your phone and you can see what ait's are, no point spending money if the intercooler is doing its job, even if the under bonnet temps seem high  and intercooler looks blocked, ait's might be good, :thumbs:

Well OEM bumper alone is not so big for FI. If you have AC still, AC radiator it is also restricting flow of cool air. 

My turbines are powder coated and after a new bumper and Seibon vented hood things have improved

peturbokitz.jpgThanks guys.

 

I was thinking about a vented hood. Also, enclosed air boxes around the intake filters with additional vents above them or in front of them so that the engine is sucking in cold air directly from the outside. 

 

You can see in the picture where my intakes are mounted. I was thinking vents in the very top half of the bumper in front of each intake with some kind of tubing coming from them directly into the enclosed boxes that I'll have fabricated. 

 

Wrap the intake piping in heat wrap to fend off heat soak. Ceramic/zircotec the manifolds and turbos. Vented bonnet.

 

I think I'll still go for a bigger FMIC. Cut the centre section louveres out of my bumper for less obstruction.

 

A whopping big FMIC grinning at you looks cool too, I think. 

 

I so want to nail these niggles because they're nothing serious but, there's just no sense in not ironing them out. Attention to detail. No one can say I skimped on the build lol.

 

Anyway, with our long winter and how suddenly the weather has changed, I have really noticed the power drop because of warmer air. 

 

I noticed the garage had only used water as my coolant, so today I drained it and got some antifreeze/coolant from Halfrauds and just went 50/50.

 

Guys, I've been considering, when I get all this nailed, selling my engine, turbo kit and clutch as a package and funding an LS3 conversion.

 

Has anyone on here done one? 

 

Are there any advantages or disadvantages?  The noise is a big advantage!!

 

Picture now up.

I don't I understand; why spent time, effort and money fixing something just to sell it off immediately? If you're going to sell it, why not do it now?

 

Wasso did an LS conversion (Don't think it was specifically a 3 though) with the Zed Shed doing a fair amount of work on it. There's a thread in here somewhere.

Not many do understand me lol.

 

I get bored quickly and my mind wanders. Of course I'll see how it goes once it's all sorted.

Trouble is that even if you do sell up and go V8, you’re still going to be spending a lot of time fault finding and dealing with niggles, so if that’s what’s getting you down about this build then it’s not going to be eradicated by swapping for a V8 kit :)

No, the niggles wouldn't bother me. It's par for the course. 

 

But, V8 sound though. Love it, especially with a big set of cams in.

 

In all likelihood I'll stick with the turbo VQ35. I'm just sounding off, getting opinions. My car is my hobby.

Boost is 4psi at the moment.

I reckon once you get yours fixed and sorted you’ll be as happy as anything, and forget all about wanting a V8 swap in the Zed.

Most likely!

 

I forget how good it sounds when there no leak/loose part in the exhaust system.

 

I hope I can properly get bay temperature down and intake temperature way, way down.

 

Is there enough room in the wings to mount the filters? Some vents in the side would look cool.

Sorry, i know i have asked but what are your ait's?

 

I totally get going fi and modifying being a hobby, got to spend your money on something and sure its better than drugs etc but, if you want a V8, buy a V8, i cant believe there isnt a V8 out there that doesnt float your boat for a 350z + V8 conversion. I get why Wasso did it, he had access to Keyser, so respectfully it was a lot cheaper than a garage doing the work at £50 per hour!

I wouldnt draw too much comparison to under bonnet temps and ait's, if the intercooler is doing its job they might well be fine and dont forget an intercooler is only effective when in direct air flow, i.e moving, if you are below ambient temp its doing ok, of course running turbos you could always get water/meth injection, more power (if mapped with the water/meth) and keeps down aits, win win ;)

This is where you need your filters to go:

Yeah. This.

 

I hear bad things about CAI but, surely that's only applicable for NA cars that actually have to gulp in their own air.
