Re: Nissan Z32 VG30DETT M24/T25 Passenger side turbo Punto GT

Cinquecento wheels on a Seicento?

Still not sold so doing little jobs.

The intercooler pipe is a bit of a mystery. Why have a turbo with a 50mm outlet and a front mounted intercooler with a 50mm inlet and standard pipe with funnels going in and out of it?

It's like trying to blow up a balloon through a drinking straw.

So I have mocked up a 50mm pipe and will replace the duct-tape with weld tomorrow. ;)

After all the effort I've put into making my GT as quiet as possible. I guess one of my neighbors still doesn't like me leaving for work at half five in the morning.

Air rifle pellet through my tail light. :bang:

An inch to the left and it would have been a new screen.

Lucky I keep spares handy eh?

Welded up the 50mm intercooler feed pipe...

...and found some wire re-enforced 50mm hose at work...

...in theory this won't expand, contract and pop off like the conventional silicone stuff.

We'll see if it works. ;)
 
I was a little concerned about the new pipe. It's 50mm and Stainless Steel reinforced but it's a high pressure water hose rated at 110'C. Can it handle the cold side of the turbo?

Had a quick Google and found the outlet temperature from the turbo should be around 140'F

140'F is 60'C so it should be okay. I'll see if I can get some 50mm Silicone pipe just in case. Glad I wrapped the downpipe. ;)

Maybe the flat spot was caused by minor boost leakage from somewhere.

So all fitted and I can't say if having 50mm from the turbo to the intercooler has made a noticeable difference but I hav also fitted some BSA light weight wheels and they certainly have. Steering is lighter, acceleration improved (even though the wheels want to spin on boost) and braking is something you do instead of think about a few minutes before hand. 195-45-15's instead of 205-55-15's have thrown the speedometer out again. 30 is now 33, 40 is 45 and so on. Even though the car is only 10mm lower she feels less like a Land Rover than before. Almost like a car.

On the sale front. I have someone coming to see my GT Sunday and if that's a sale I have another Punto in mind.
 
I arrived at work without issue but was greeted by the smell of burning plastic. :bang:

Then I remembered I work in Wisbech so that's completely normal. :devil:

The new pipe worked brilliantly and this morning even though I'm sure it psychosomatic the engine was simply perfect.

Why sell it when you are having so much fun??

Sadly the car has a major problem. I love the idea of it looking like a shed with a bit of lump under the bonnet. We all like a bit of stealth right? The suspension is terrible but the car handles really well. The engine has gone from a cement mixer though a loudhailer that I was embarrassed to drive to one of the best Punto GT/Uno Turbo engines I have ever known. No, the problem is; none of it wasn't my idea, my build or my vision. Even though I own and have done a load of work on the Punto it has never really felt like my car.

That's the thing about "unfinished projects". Do you strip them apart and start again or finish them off? I should have ripped the Punto apart and started again from scratch but because I have been using it as a daily driver this wasn't an option. All I have done is repaired problems and made a few improvements.

Time to move on.
