suggestion on a turbo for my d16
 

hey guys i got a d16z6 with eagle rods and srp pistons... i am boosting this i am just seeing i found some nice t25 flanged manifolds and stuff just wondering what a turbo would be for a quick spool but still good to maybe 400hp i am lookin to run around 300-350 but maybe leave some room if i want a hair more.... then also i found a nice t3 t4 turbo set up.... what kinda turbo ya thinkg would be good for that set up?......maybe a 50trim with a ar63 to help carry the boost?

i am a super noob with turbos so any help is good help thanks guys

400hp is a lot to achieve.

Best advice is to use the search button up top before you get banhammered.

Re: suggestion on a turbo for my d16
 

If you truly want quick spool and 400whp you'll need a Ballistic Concepts chra. If you just want 400hp any combination of a good sized t3/t4 will do you just fine.

Re: suggestion on a turbo for my d16
 

t3/t4 60-1. I have one forsale

Re: suggestion on a turbo for my d16
 

Holset HY35 or HE351CW / thread.

+1

Re: suggestion on a turbo for my d16
 

Holsets are your best bet for bang for you buck. All depends on what you want to spend. If you search you'll find a Super Budget build making over 400 off a holset and cast pistons. Take a good look into the forced induction section.

Re: suggestion on a turbo for my d16
 

holset FTW. and it will want more then you do so its a good turbo

Re: suggestion on a turbo for my d16
 

Yeah but Holset isn't fast spool. IMO fast spool is about the same as a factory turbocharged car. So if you want that kind of spool and the size to be able to make 400whp; then you'll have to get the Ballistic Concepts chra. There are lots of journal bearing turbo's that can make 400whp, but they don't spool as fast as a stock turbo. Even with a T3 turbine; the compressor is still much larger and takes longer to spool. I guess it really depends on what your definition of fast spool is.

Avoid the T25 flanged ---- for anything more than 325 whp. I dunno, a GT2871R might do the trick, but the Garrett GT3071R with T25 turbine did nothing but spool super late and leave very little usable powerband, due to the turbine restriction you'll make at most 410 whp off of it. You spool 2000 rpms quicker off of a run of the mill T3/T04E with .63 AR turbine housing, and it makes more peak power too.

Holsets are good bang for the buck as well.

nice i think i may go with a t3t4 .50trim with a 63ar? or somthing i guess i will be getting full boost some where around 4k? if i am lucky....that way i got some room to play to maybe make high three hundreds....

and say i buy this t25 flanged kit is it a bad idea to use the adapter plate to a t3 flang?e

Re: suggestion on a turbo for my d16
 

You will be getting boost by 3000, 10+ psi by 3500.

If you go GT3071R with T25 flange you'll get this, which is bullshit powerbandwise even if it wasn't twice the price of a brand name T3/T04E:

Re: suggestion on a turbo for my d16
 

so what excatly is the t3t40E campared to the t3t4 60-1 and Holset HY35 or HE351CW is there anyways to explain this to a noob... and price ranges for these turbos new....

my friends knows quit a bit about turbos so when is show him these ideas and stuff he will better explain to me as well to...

thanks for all this help guys

T04E compressors are going to be .50 (popular on D16 and Mitsus and others), .54 (rare, used to be seen on LS Drag kits), and .57 or .60 which you see a lot of on B-series although they don't spool much later on D's. 425-475 whp turbos, inexpensive, robust. Try to get a stage 3 (the most common, incidentally) turbine wheel with .48 or .63 AR turbine housing (I'd go .63... spools marginally later but chokes top end flow a lot less). I really think one of these is the turbo for you, they aren't super expensive ($575-ish new) and with the recent economy woes you can find real deals on them if you are careful and only buy from reputable people.

I'm going to tell you about the others you asked about, but it's for you to understand not because I think you should run one:

The 60-1 is a T04B compressor good for 550-ish. It's an old design, but a very good one, which is why it's still really popular. They spool a bit later than T04E, even when married to the exact same T3 hotsides, because the compressor is bigger and heavier and due to flow dynamics and stuff.

You can think of HX35 and GT35 as similar, albeit more modern, compressor designs; comparing 60-1 vs HX35 vs GT35 is really easy in my mind. I really don't like GT35 due to price and how poorly it spools (only thing worse is GT30, spools just as late but makes less power :1) but it's more efficient (makes more power) than HX35 in the lower boost range. Both HX35 and GT35 have larger/laggier turbines. The HX35 is not very popular because, despite the great prices on them, they are physically massive and don't always fit correctly on the average shelf manifold meant for a T04E/GT35/common-sized turbo.

awsome well i think i will be going for a t3t4 turbo probably a .50trim with a .63ar or somthing.......but if i get this litle greddy kit i am just going to try to run the piss out of the turbo and have fun... and then look for a up grade probably get a adapter plate for a t3 flanged turbo

Re: suggestion on a turbo for my d16
 

on a side note, is the easiest way to tell the trim and ar of a turbo just to strip it and measure?

or do all you turbo experts out there just know what the ---- looks like

Re: suggestion on a turbo for my d16
 

Meh, a bit of both. Sometimes pictures mislead you, while there are a lot of the really popular units there making up 75% of what you stumble across there are literally a couple thousand possible combos.
