which one ? I have got a choice of using either of the turbos on a

rb 30 all I can find out is that the hks will flow 800 & the greedy 820hp apart from this will there be any marked difference, ie being a later design will the t 51 be more effecient & hence spool up quicker giving boost earlier ?????????????? or is the greedy the 'one' to use, cams are 280& 290 with 11.2 lift, bottom end is a giken 3 litre kit

help would be really appreciated, the only spec sheet I could find was this one, unfortunatly it tells you very little about the greedy.

You don't have the option to try different turbine housings to adjust the boost curve with the HKS units. Both are rebuildable so it's not an advantage either way. There are more options with compressor as well with the Greddy T88 series. The T88's also weight alot more and are physically larger than the HKS units. Is the Kai a ball bearing one?

I had a t88-33d on my rb25 - not much of lag difference between it and the gt30 ( knowing that both turbo's are completely different and the t88 being able to flow much more and was not bb). The t88 i had was a great turbo. Supposedly rated at 850hp?? can some one confirm the hp rating of t88-33d's.

I can recommend the t88 though i do not know much about the other turbo.

it's here, 820 hp

I have just been told that the diamentions of the t88 34 D are very similar to the kai, so if the wheel sizes are the same as the 34 D & it only flows 800 as opposed to the t88 34s 850 ,it is not looking as good as the greedy ? or is this a compromise & it spools easier?

so check this chart out, it gives the comparisons but I must admit I do not know what it will mean in real terms ? I see the comp ave on the 51 is higher ( whats comp ave ?) & all the sizes with the exception of the inducer major dia are bigger!(does this mean that it's got a bigger exhaust wheel) ? but on the other list It say's that the 51 flows 800 against 820 for the t8833d, what does comp ave mean ? what I am really trying to establish is which one, if any will be more road drivable ?

is the first list accurate at 800 for the kai?

      R34 power steering

      Thanks, plan is to drain all fluid tomorrow and do smoke test to find out the leak.   Appreciate your help and want to understand how the system work. So cooling is achieved by the long loop not any rad? The diagram seems to suggest it connects to somewhere inside the cabin and I thought that is a cooler inside firewall. If you look at the diagram it seems to show it connects to something inside firewall. I tried chasing it but not easy unless I take loads off   i am confident pump is good as fluid goes in and it gets soft( steering) but as soon as I turn engine off , loads of bubble come to surface and overflow. When engine is on , fluid level is below minimum but when off it shoots off and thinking it is sucking air in. I suspect aluminium pipe may have a crack line or whole   smoke test with no fluid should be a good start and if needed will remove the pump   In addition, the one going under the engine bay is high pressure line and one directly connecting from pump to resorvoir is return/ low pressure?   finally I searched and suggestion is to use dexron 2 but that is discontinued so bought dexron 3 as all research suggest it is compatible and shouldn’t cause any issues/ blow seals. I bought two liter of dexron 3 motul atf

      Don't worry about. Just don't try to drive hard enough to make boost and you'll be fine.

      Yes. This has already been said. It is a loop of hardline in front of the radiator. Because.... the pump is on the LHS and the steering rack hydraulic connections are where they always are on a RHD steering rack....on the RHS. The high pressure line goes down under the engine, along the crossmember, like it does on all Skylines. Don't just throw expensive braided hoses/other kits at it. Work out what is wrong and fix that.

      Still got the afm on the intake, clamps are shut tight, only loose hose is the one that goes from the j pipe towards the IACV, since it's next to impossible to find a factory hose and the barbs are different sizes (I'm still using clamps on this hose to try and help it seal on the iacv side) I've ordered parts to make up the hotside of the intercooler pipes, I'll plumb it in and see what happens in a few days I suppose The turbo's internally gated, can I just unscrew the tension rod to let the gate open?
