Lindsey gives you an option of either the #8 or #10 kkk hot housing on their super 65 & 75 turbos. Lindsey Turbos
Which turbine wheel do you think they use with the #8 option. Stage 3 or Stage 5 ??? What application calls for a stage 5 turbine wheel? Track? What spool characteristics can one expect with a stage 5 wheel?

those larger options are for 2.8 and 3.0L engines.

 

Well,
If your looking for huge top end and a lot of turbo lag (like 4500rpm spool up) then go with a #10 hot side (okay for the track). The #8 hot side is the same as the Turbo S in size. But with the Lindsey turbo, they have lighter internals so it will act more like a #6 hot side (stock turbo) as far as spool up. So, I would go with the #8 (thats what I have with a garrett T4 compressor) As far as stage 3-5, I have no idea. Maybe someone else can give us a lesson on what they mean by that. But for sure you will wait forever to get full boost with the #10 hot side. And for me, it's not how much boost you have, it's when it's avalible (the sooner the better).

 

No, they are not, they supply them for 2.5's also. When I spoke to them they would have been happy for me to run a 75#10 on my 2.5 when I said it was track biased. I went for a #8 and I asked about the 65. The reply was something like "it isn't as good as the 75 and there is no point going for the 65, it was in the catalogue before the 75 but in every application for the 65 the 75 is better". Given that they cost the same I figure they had nothing to gain by pushing me toward the 75 unless what they were saying is true.

In terms of how it is on a 2.5, it comes in quite late and very hard and it holds to 7,000 rpm no problem at all. I wouldn't suggest it as the ideal street turbo but for my track biased car that might go 2.8 in the future I think it was a good choice.

 

Maybe Bret meant ,they are better suited for a 2.8 or 3.0 street car rather than a stock 2.5ltr. A track/race engine and using the upper RPM's is something even more different.

 

thanks evil, yes I should have said "better suited" on a practical purpose. Fen even you went with a #8 housing.

 

The stage 5 wheel and #10 hotside are WAY too big for a 2.5. The LR Super XX are relatively not very popular turbo's so I am not sure how much information you will get on them here.

 

I thought by "those larger options" you meant the 65 and 75 but I now think you meant the #10 vs. the #8, so my reply was perhaps not correct in the way I believed it was.

I did go for a #8, and to be even more fair I went with it with a view to going 2.8 at a (not much, hopefully) later date. I actually talked myself out of the #10 though and Lindsey (dunno if it was Dave or not, didn't ask) were suggesting it's an easy swap if I change my mind. It is just the housing apparently. The recommendation when I said "track" was the 75 with #10, even on a 2.5 but I just thought there is no way a 2.5 needs the biggest turbo Lindsey offer.

To be honest I wanted something big but not too big for a 2.5 and I'm no turbo expert but as I understand it the 75 (and 65) is a TO4E based AIR60 compressor (which seems to get good support from people on here) with a KKK hotside so I didn't need to modify the exhaust flange. Trims I am not so sure about but I think they are deliberately secretive about them so there was nothing to research.

 

Hotside trim (stage 1, 2 3 and 5) are for the size of the hotside wheel. After the stages, comes N, O P and Q trims.

The bigger the trim, the slower the spool, but the greater the top end. Stage 3 trim is among the popular for street cars:

 

Hosrom - I swear if you post that Garret page ONE more time, I am going to fly over to UAE and kick you in the ***.

 

Yeah, i am over doing it, it is all in the archives anyway

Regardless, come over to Dubai, get you're self a camel ride, it is faster than you're car......in the sand atleast

 

 

"The stage 5 wheel and #10 hotside are WAY too big for a 2.5. The LR Super XX are relatively not very popular turbo's so I am not sure how much information you will get on them here."

I think you would be surprised just how popular they are. And yes I would know. And yes you would not.

Wes, obviously you have the number of units sold as you work for LR, what I am saying is, you DONT hear about yay here is my LR XX turbo much at all, what you DO hear about is, wow here is my Vitesse Stage X turbo, spools amazing etc, or about GT series turbos, or whatever...

I doubt I would be surprised at how many turbos with #10 hotsides and stage 5 wheels you have sold to 944 owners with a 2.5

 

NZ. You have pretty much reached the power of a stage 3 turbine on your car. To go past that you will need a stage 5 or larger.
