Hi all,
Just wanted to put this up as it's been in the wings for a long time but now they are finally in.
Pretty sure this is a first for the GT-R.
My car is at Litchfield's in the UK waiting to fire for the first time with these in place. It went in originally for a forged engine build but in the process the turbos became available and having read about these for years in other vehicles I was really keen to be a guinea pig for them. The car previously had stock manifold garretts. Can't remember exactly which but they were Litchfield stage 5s making 770bhp at the flywheel and 710lbft on stock internals and 93 octane fuel.
Main advantage to these is meant to be spool. They have a gamma titanium exhaust wheel which reduces boost threshold and significantly reduces transient response. Like for like they out spool garrett along with many other advantages.
Basically BW started with a clean sheet and designed an aftermarket turbo from scratch with a wish list of all the features they'd like to incorporate into a turbo for people like us who mod their cars. I'm led to believe that the likes of garrett gt ranges etc. are simply evolutions of oem turbos complete with the compromises they bring.
I've gone for the smallest option in the EFR range which is rated as a 450-500hp turbo. Am hoping for almost stock spool. It's the 6258. I did have the 6758 originally but really wanted the smallest possible as I am chasing ultimate road use rather than maximum power. In truth, the these are the only two sizes available currently that can be made to fit and they are only rated 50bhp apart.
For my present phase of gtr (my12 btw) these have been shoehorned into the one piece stock manifold and exhaust housing and the stock nissan compressor cover as this is currently the only way to make them fit. They are much longer than the equivalent garrett which is probably why no one has managed to fit them yet but litchfields have worked a little magic with the help of turbo dynamics in the uk. Sadly doing it this way means they won't be as efficient as the stated power output but it's all we can do for now.
After sema, I'm expecting an external waste gate version of the exhaust housing to be available (sometime before the end of the year) which I intend to use along with litchfield's cast log manifold (also due for release) as the combination of these means the extra length of that set up will be offset by slightly different pipe work geometry. Given the test results of the log manifold combined with the proper exhaust housing I'm hoping it will spool like a mofo but also go on to around 900 on what you'd call 93 (we call 98/99).
I'm expecting some nice pictures from Iain Litchfield which I'll post later today.
Sorry for the two step post but I had time to write this now, and won't when I post the pictures.
