Compressor Specs?

get a bigger turbine wheel!

and maybe a 60-1 compressor wheel ?

look at jason's turbo pick to give you an idea …

Yeah I've read the turboupgrade.html page and all of that, I'm just interested to see what others think also as those are the specific choices that have been given to me by the place I'm getting to build it.

the TO4E will be more DD friendly, TO4S if you consider more power

tips? dont get too wild with the ratio between comp/turb and itll be smooth

Yeah that's what I meant by matching, I figured you'd have to keep the diameters between both wheels as close as possible to maintain the pressure ratio. Plus going by this picture here the T04E looks like a tight fit as it is. I dont even think the T04S would fit in the stock location.

The turbine wheel is Stage 2, so any recommendations on compressor wheel besides the 60-1? Anyone with experience using a few different sorts care to explain the pros/cons the 60-1?

You should be more concerned about the wheel than the housing. The size of the wheel is going to change the way the turbo feels more than anything else. An E and an S cover are just the housings. Do you want a 3 inch inlet and 2 inch outlet, or a 4 inch inlet and a 2.5 inch outlet? The holset HX35 comes with a compressor housing very similar to a garret S housing, and I have used a t66 with an S cover in the stock location.

What horsepower do you want to make? Pick out a turbo that will make the power you want. Don't pick out a turbo without a power goal, and don't pick out a turbo based on where you want it to spool.

I realize they're only the housings, it's just the details I need to specify as I was given the option of either housings so I have to make a choice. I think I'm going to go with the T04E just to keep things matching as best as possible. I'm finding out about the available comp wheels now, any suggestions as to what I should be looking for? This setup isn't for crazy power, this is for my 89T which is just a street car so I'm looking for 350-400rwhp max in the future.

This isn't a "I need a turbo, what should I get?" thread but more a "I know what turbo I want, I have a shop to build it, now I need to know exactly what specs I should get" thread lol

I would stay away from the stock turbine housing. It sounds like a holset would be perfect for your application.

A bit too much bullshit involved, I need easy. I have a custom turbo setup already in the works for my 86T, I just want a simple solution for this car.

I can get a stage 3 turbine wheel, but it wont use the stock housing. It will be a 5 bolt housing but they can provide the matching flange, should I do it or is stage 2 good enough?

If it's too complicated, don't do it. There is nothing worse than putting parts on your car that make it perform worse than you wanted than if it was stock. Picking the wrong turbo will be just that.

Take a few days to decide the hp levels, the rpm range, and intended usage. Those three things are not complicated or hard. From there people can guide you with minimal effort on your part.

Yeah I have been on this for a couple of days already, there's alot more bullshit than I realized with these hybrid turbos. I'm trying to keep it as simple as possible for this car so it just bolts up and off I go.

So far this is what I have decided,

T04E a/r 0.60 (I could go with 0.82 but again, not bolt on)
Compressor trim 60
Turbine a/r 0.63 (stock)
Stage 2 Turbine Wheel (65mm wheel base/55 trim turbine wheel)

I was wanting to go bigger, but after talking to a few people I'm going to get butt hurt on boost response if I do and considering this is a street car that will be a deciding factor so I'm trying to maintain as much of a balance as possible. The T04S housing looks so darn cool though! :P

I'd like the boost response to be good, anything under 3,500rpm-4,000 is fine by me really. As for HP levels, nothing crazy around 300rwhp is fine. Intended usage? To kick Skyline asses, even more than I do now that is! Oh I mean, street car!

That turbo I was telling you about that my buddy is torn as to if he is selling or not, is a TO4E housing with a compressor wheel that will do 500whp. It runs a StageIII turbine wheel with a .63 a/r. He runs the OEM W series turbo engine and has absolutely NO problem with that thing spooling. Full boost of 16psi by at most 4k rpms, and when it comes on, it comes on very strong (mainly due to the B/C he uses). A stage 3 with a .63 is still very small on a 3 liter engine. I think nissan should have went with that for OEM instead of as small as they did. I highly doubt anyone would have been disappointed with boost response.

As I said above I can get the stage 3 wheel, but it no longer fits in the stock housing and I'll have to go with a 5 bolt and then use a matching flange so it bolts up. No big deal really, I just wasn't sure if it was neccessary. How far should I take it though? Should I also get the t04e overbored to fit the 60-1 compressor wheel? Wouldn't that coupled with the stage 3 wheel reduce spooling time significantly then? Or should I just go with the stage 3 turbine wheel only? I know this is noobish shit, but this turbo will be coming all the way from the U.S so I dont want to cock up the specs.
