I am looking through the pictures you sent me and as you use stock internals what happened here?

 

Well, when I first got this car we did a lot of research and development with different turbo combos that were available at the time.

 

The very first time I put the engine together, was with "super t28" turbos which were basically stock exhaust housing with bigger turbines stuffed into them. This is a bad idea because at higher boost levels they generate mostly heat. On top of that we tried to do some fuel tuning by ear at the track which was also a bad idea. I ended up with too lean of a fuel mixture which resulted in a nice hole in one of the pistons.

 

After that I switched to new greddy kit which worked pretty well. As you know this kit is not really meant to be for a street car. The wastegates are vented into the atmosphere(extremely loud) so you can't hear the motor. I learned my lesson about the quality of pump gas then and ended up redoing the exhaust piping to route the wastegates back into the exhaust. Now I can finally hear the motor again, because I want to hear the motor in case it pings or detonates. I also tuned the car on 100 octane and that was the ticket. About three years so far with a nice healthy motor that performs well pretty consistently.

 

Sometime you have to be brave and try new things. Sometimes they don't work, other times they do. :-)

This is strange as this was the very reason given to me as why we should not have them venting into the atmosphere.

 

 

Apart from the noise could you smell the fumes inside the car?

 

 

So when you broke your piston you just replaced it with another stock one and not forged?

No fumes inside. Yes I've always had stock motors.

Thanks Zo I forgot who said the fumes would get inside the car now :confused:

i said it would be a possibility & not a good idea for a road car ;)

CJ are you taking note?;)

piss off :slap: :rofl:

 

you really think i shoudl get them plumbed in - i have been thinking about it

You don't necessarily have to. But for me it was important because I can not trust pump gas and have to listen to the engine for detonation, if it happens. There's no way I could hear even severe detonation when the wastegates were venting into the air.

I don't see any gas fumes coming into the cabin unless you had holes in the floor of the car. The dump pipes are pointed to the bottom anyway.

On your pics they are not in like mine?

Aha I see now;)

 

Good god.. things have moved on a bit since the last time I looked in on 300zx-land. Hope that goes as well as it looks like it should when it comes back from the shop, be good to see more low 1/4mile times in the UK..

Yea this is Zhounds car running the same turbos in the mid 10s :bow:

Did you get your bigger throttle bodies in the end Macca?

Not at this mo,but the car will be having many more parts in the next few months.

 

Wait for it................................................

 

 

 

 

 

 

 

 

Looking at a six throttle bod conversion :shock:
