The Garrett Gt30r Thread - Lots Of Info And Q's

Well done Andrew. This is going to be very interesting to see what it produces, and more importantly - how it delivers.

Presumably running the cast HKS manifold, what size gate are you going to use?

Awesome, this is going to be quite interesting

Hi Dale

It has the standard HKS gate for the cast manifold with the divided port feeding it. I am not sure what size it is.

Slight hiccup this morning getting the oil pickup sorted on the engine so it might be delayed a bit unless something simple works.

38mm i think they were...i got one here, if anyone knows where i can score a hks mani i will use it..

[Dale FZ1]

How well does this baby fit up in the engine bay for clearances? I seem to recall issues with engine mounts for some owners previously.

[wolverine]

It will fit in fine since there is already another GT30 turbo on there now. The engine mounts needed to be trimmed a whisker but otherwise it goes on fine.

The oil pickup has been modified successfully so only an hour or so wasted.

It looks like it will be Monday at the earliest that it will be fitted now.

standard hks gate is 38mm on the cast low mounts.

very interested to see how it goes. i have the larger 1.06 T4 ATP housing with the same manifold but havent had a chance to get it on the dyno yet. Atleast fitment should be a little easier with the T3 housing.

And things get more interesting. Do you have the exact same turbo, just with a larger turbine housing? Engine spec?

These two are going to be worth watching.

56T 3076, used to have the .82 IW housing on the standard manifold but swapped it for a T4 1.06 T/S ATP housing and hks cast low mount last year, at the same time as going to a 30det. motor is a standard 25/30 with the usual shit. havent driven it much with this turbo setup due to other engine issues but it made noticeably more power than the old setup. hard to compare spool times when so much was changed at the same time but the 1.06 housing wasnt noticeably laggy and it made great torque everywhere, loved timing a lot more than the old setup aswell.

[Harey]

That sounds like an awesome setup! 25/30 with 56T 3076 with T4 1.06 Twin Scroll housing, awesome reponse and great power. Keen to see your final result and dyno sheet.

[JonnoHR31]

it'll be a long time before that happens, having some engine troubles and havent found any motivation to touch it for a few months now....
