Half Bridge Turbo Suggestions

[BlitzBoy]

Got my EGT probe fitted this time for this years fun, are you fitting pre turbo or post?

[AshRX]

post in downpipe. Wont be assssssss acurate but will help big time

got told pre turbo can eat the probe away very easily.

[BlitzBoy]

yeah it does shorten the life, hopefully it will last long enough to map to 1.5 BAR

[AshRX]

should be just hope it doesnt snap off in the turbo housing lol

right turbo off this week to take all the measurements

Hi Ash,

It may to sit down and decide if you want driveabilaty or out and out power from your car,

With the smallish hot side your present Turbo has I would suggest it should spool up quicker than what it is, so it may well be the way the engine is ported that is causing "your problem"

If you just want the car more drivable then maybe a TO4Z will help (Mark has lots of experience with these) bearing in mind Chris Impey ran 10\'s on one of these, or another to consider is the GT40 on a T4 flange,

I would however stay away from the GT42/ GT45 family as you will end up with a higher boost threshold than you currently have,

Hope this helps,

Don\'t forget also the with a different Turbo the positioning may be different as well, needing at least a different down-pipe fabricated

Clive im running a GT47 at the mo and the T51r Kai and SPL are same size as what i have. I have been told by a reputable turbo company that the GT4202 is the same size as these. Turbo is coming of today for all the measurements to be taken. Just hope i have enough room if i have to make a few modifications

Ash this is what a proper GT47 Turbo should look like(pictures below) and what it can do on highly tuned cars

wish mine looked like that :rollin

have massive front housing on mine and a lot smaller rear. Spoke to Garret and they have no listing now for it so it was probably a hybrid. Not cheap to repair.

Getting told so many different turbos to get just not sure what to do lol

The engine was built by John and RE:Worx as the potential for a 10 sec car with the RE engine and half bridge, polished this polished that. Engine is fine no problems there. But i do use it on the street and so I have to take that into account. Its not a daily drive so can bear with a bit of noise and uncomfortable drive.

Dunno what to do :Nono!:Nono!

I would suggest something like this,ball bearing version:Thumbsup!
