been thinking of getting a new turbo , so whats the best mods to get these to work at there best , cams head work etc etc .
car will be standard bottom end 70mm airtec cooler 55siemans will be using the twin scroll mani aswell
cheers

 

Mine made bonkers power just on a std 4x4 engine using a proper twin scroll manifold. it Made 469bhp and loads of low down torque. It would run 530bhp if I did the head, cams and pistons with long studs. (And no doubt last a lot longer)

 

cheers bud , what was it like on the standard 4x4 box

 

After mapping Mark Shead gave me the keys and said to use it in low boost only (420 bhp and similar torque) as he said the box would not last long. As I drove away he said "I would get an Oppliger or Bara box on order now" (My box has done 36k from new) I drove the car home and did less than 200 miles before the first motion shaft began to clank and 2nd gear then clonked, I had not tried high boost and I hadn't launched the car at all. I now have a Skyline box with 2wd and 4wd options on an ETS pro controller and I have fitted a Supra rear diff with billet case and then I got bara to build me a strengthened quaife front diff so hopefully it will now take the torque. I have since tried full boost and it is mental. I do not believe the std box will take the low down torque. There is a 2nd hand bara box on here for Ł2800 in the for sale section.

 

I would be looking at a Hart/AS inlet plenum to make the most of the turbo and ex manifold

 

I have added the hart inlet after mark did my mapping, I can see that the air flow in to the engine looks to have a better path and people say that even a spacer on the std inlet makes a difference but I do wonder if the inlet will make any noticeable difference next time the car is mapped?

I had my inlet zircotec coated to match the exhaust for colour more than anything but they suggest it can help to protect the inlet temps but in theory it could also keep any heat in there too.

For me I think getting the best intercooler in there would be the biggest improvement as the inlet temps were holding the mapping back, I wouldn't want any more power or boost yet though until I have it long studded and a good head gasket and rebuild.

 

loving turbo new high tech

 

i think when they bolted one to rods it added bhp

 

What management you using?

 

yeah the top feed intercooler by SpecR will see an improvement in bhp and torque too for the same or less boost.

Gonna be knocking on 500bhp at this rate
