Turbo Parts list

[sykikchimp]

I am planning to run a modest turbo setup. Max 10-12psi, probably 6-7 psi daily driven.

This is the list of components I have put together that I would need.. Can you tell me if this would work or if I'm missing something?

Fuel:
370cc injectors 95+ 300ZX Turbo
jim wolf ecu
Walbro Fuel pump
Adjustable FPR.. (is this necessary??)
Turbo/intake/exhaust:
turbonetics T3 (maybe you can make a suggestion here.. I would like quick spool, but I don't want to push the turbo beyond its limits when pushing 12psi)
Revhard Manifold
Tial 35mm Wastegate (maybe you could make a suggestion here too?)
2 1/2 downpipe
Exhaust -possibly 80mm 5zigen
starion intercooler (or equiv.)
Custom IC piping
Oil Pan with 1/2" fitting for oil return
Feed oil from 1/8" BSPT fitting attached to oil pressure sender. (maybe there is better way?)
Other:
Spark plugs w/ 6 cold rating
Gauges: Boost; Air/Fuel; Fuel Pressure or Oil Pressure?
Random Fittings, and SSteel braided hoses..

This is to get me going.. Later I would get an Electronic Boost controller, and turbo timer.


Any suggestions as to different parts that would work better or equal?, or parts I missed? Would help me out greatly! I feel it's about time to get serious about this project.

u dont really need the regulator- its covered

sounds great though
i have a turbo for sale if u want it $550
t3/t04b stage 3 turbine wheel, .48a/r 60-1 trim and thermocoated
perfect for fast response and low boost applications

[sykikchimp]

Very possible on the turbo.. did you buy it new?

[Jeff240sx]

Hey, do you have any idea what that setup is gonna cost you?  And no,  you don't need a FPR, since you have the JWT ecu on your list.
A T3 would get you plenty of boost, since z31.com says it is good on a 3.0L v6 up to 14 psi.  And this is a lot more air to push than our 2.4L.
I would get a t3/4 though.  It just seems like the thing to do.  Since you will have the JWT ecu, and intercooler, if you get a larger turbo, you will have room to upgrade.
A lot of people get a turbo bug, and gotta go faster.  Duy, PSI240sx, Boosteds14, Chris May.  They are all switching or switched their turbos.  Cuz you'll realize you can go faster, after putting $1k into your car on pistons and rods and injectors.  Then you crank the boost, cuz you're a guy, and thats what we do, and you'll hit the limits of a T3.  Better to have a larger turbo, proven on Boosted's car to run 22psi, than pay $xxx.xx for the t3 and have to find a t3/4 for more $$$.
On a side note, I think I will have 5 gauges.  3 in a HKS Din-sized panel and stick it in the slot under the radio, and 2 on the a-pillar.  The A-pillar will be the most looked at ones, BOOST, and Oil Pressure.  Cuz a gain or loss in either will blow a car up.  Then in the Din Panel will be a Fuel pressure, EGT, and Oil Temp.

Jeff,
What turbo you gonna upgrade to when you sell the t3/4b?
-Jeff

[sykikchimp]

Boosted - what did your car start to spool at? &nbsp;when did you reach max boost? &nbsp;When should it reach full boost at 12 psi.


I think I would rather have smaller turbo for now so that I'm NOT tempted to turn up the boost. &nbsp;But I may consider the T3/4 anyway

Yeah I realize it's a lot, It would be put togther peice by piece by piece.. &nbsp;And I would buy a lot of it used, and off ebay etc.. &nbsp;I think I can do it for about $2000.

The money is one of the reasons I asked. &nbsp;To see if you guys had any cost consious options..

wouldn't the engine blow from changing fuel pressure? are you talkin about detonation from lean/rich? if so, isn't a a/f gauge more important? Please enlighten me with your knowledge. Also explain other gauges too..(like effects of high exhause temp)

chimp, I say you need a bigger MAF then the list will be complete. And you should get turbo timer first before, say, turbo upgrade. I would do the booster control too... so you can feel higher boost from original turbo.. &nbsp;

thanks

i am getting either a to4r from my friends supra or a t60 new! not sure yet, i have to see how much turbo lag i will get and have to take a look at the compressor maps.

he does not the need a bigger maf because he is using 370cc injectors with the jwt upgrade.
u need a bigger maf for more than 12psi and the 50lbs injector setup by jwt

[sykikchimp]

Ok.. After pricing some stuff out, I think it would be cheaper to find a used internally wastgated Turbo. &nbsp;
Any ideas?

[rancid240]

I was told that an 81-83 280zx turbo would be good for my sohc setup...but i think a universal t3 would be much easier to find, since tons of cars carry them. &nbsp;also, i was told that for DOHC you need an AR of .63 or higher, but dont quote me on it. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/lookaround.gif" border="0" valign="absmiddle" alt=':look:'>

[mbmbmb23]

BOV, high-flow cat, K&N, new hangers for aftermarket exhaust, forged pistons & rings, cobra MAF, metal head gasket (if anyone makes one for the KA), porting and polishing??, new fluids for engine, compression check & heavy duty weld the starion FMIC, shipping and handling costs for shipped parts.

Thats all I can think of. Sorry to be nit-picky.

Dude, you're a nice guy and all, so I won't flame you for bieng *helpful*, and I won't flame you for not reading, either.
But please do read next time he says the words "MODERATE boost" and "Complete for $2000."
I know that z31s have a t3 turbo on them. &nbsp;And they are internally wastegated. &nbsp;
I am trying to talk Rampid360 into a cost-effective turbo setup. &nbsp;z31 turbo, rebuilt $300. &nbsp;Custom made manifold (he knows people) $200. &nbsp;Bosch BOV $35. &nbsp;Turbo Timer $30. &nbsp;Boost, EGT, and oil pressure gauges and pod $140. &nbsp;Pipeing can be made from radiator hoses and an exhaust shop can make a downpipe for $100ish. &nbsp;That is like 6.8 psi (stock internally gated boost pressure from a z31) for $805. &nbsp;But the stock fuel system can't handle near 7psi, so you gotta somehow lower the internal wastegate pressure, or add injectors and JWT ecu for another $800ish, and then you have a barebones $1600 turbo system. &nbsp;How do you think you can do your setup for $2k. &nbsp;Please let me know, so I can pass it on to him. &nbsp;

Sorry, I was quoting in my last post, and couldn't read this post to answer. &nbsp;
I would like to have redundant systems in my car, just incase. &nbsp;Cuz I like my $3k turbo and $10k car. &nbsp;And I like to drive it.
Anyway, a breakdown of gauges and what they do.
Boost - Duh
Oil Pressure - If a line blows, the oil pressure will drop. &nbsp;If you keep driving without oil pressure, you have now cooked your turbo, and possibly seize the engine. &nbsp;If it increases (dunno how it would) it would blow a headgasket.
Fuel Pressure - Just like to know.
EGT - Exhaust Gas Temp. &nbsp;Kinda like a A/F meter, but I think it's better. &nbsp;An A/F meter goes by a scale of 11 - 17 or so, and is hard to tell how your engine is running. &nbsp;But exhaust gasses can change by tens of degrees really quickly, and thus would be easier to read and rely on. &nbsp;If the gasses get hotter, you are running lean. &nbsp;And if the temp gets colder, you are running too rich.
Finally, the Oil Temp. &nbsp;Since our cars are 3.5 quart + filter in oil capacity, we have one of the smallest oil capacities per liter of engine that I have EVER seen. &nbsp;And a turbo is going to increase that temperature by at LEAST 20 degrees Celsius. &nbsp;And anything over that would necessitate the use of an oil cooler, that isn't in my planned 3-month budget. &nbsp;And if it rises extremely fast, it is a backup, and means I am probably loosing oil from somewhere and my other REALLY IMPORTANT gauge is not functioning properly.
If you have any other questions / comments / complaints on this post, post here. &nbsp;Also, if you have any ideas of other gauges I would need, let me know.

[rancid240]

if he can get SOHC manifolds, i'm interested for $250. he can keep the $50 profit.

one question that i've been pondering...once you ahve the turbo and manifold bolted in, wont you have to tow your car to the muffler place to get a downpipe made?

[Jeff240sx]

Nah. &nbsp;I intend to hook up some flex hose, or if it will work nicely, 2 45* or 90* bent exhaust pipes from AutoZone, and hook them together, and let it run open, just before the cat. &nbsp;And drive 45 miles like that to the mandrel bending shop in Sarasota. &nbsp;Hopefully not getting a sound pollution violation on the way.
-Jeff

[sykikchimp]

ok.. lets modify the list with prices for the Initial setup:

Stock injectors ~Free
Walbro Fuel pump ~$115
Vortech 10:1 FMU ~$140
T3/T4 from Buick Grand National ~$350
Tial 35mm Wastegate - ~$250
Need a custom manifold I want to spend $200-300. &nbsp;Can you help? &nbsp;Thing is, the GN manifold flange is a 3 bolt center inlet.

Custom downpipe w/ flange made to cover wastegate. ~$100
Intake piping I could make myself out of several prebent pipes and elbows for ~$50
Random Hose's connectors, and fittings ~$150
~~**Can you tell me where your getting these:
Bosch BOV ~$35
Turbo Timer ~$30
Gauges ~$140
I'm Contemplating leaving out the Intercooler initially, b/c I'll only be running 7psi max

total = $1660

Depending on if I can run the internal wastegate, I could drop the tial, and it would cost $1410

[sykikchimp]

I found some T3's from ford thuinderbirds for 250 too...

Ooops.....missed the part about "under $2000".....thanks for not flaming me for that. &nbsp;Under $2000 huh....well.....scratch off all the "internal engine mods" I listed. &nbsp;I was a little helpful....he's got a BOV on the list now <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''>

[Jeff240sx]

Do you have money now? &nbsp;Just part to buy a few things off ebay? &nbsp;Cuz here are some decent items to think about getting.
For the gauges, I was thinking the 3 that you were looking at, AutoMeter, and $40 each, with a $20 gauge pod.
Tips on MAKING you Bov.
DIY BOV #1 &nbsp; DIY BOV #2
Here are places that sell a bosch bov unit.
Compu Parts &nbsp;
Jackson, New Jersey &nbsp;
1-888-779-7710
~$27.50 plus shipping
ABJ Auto Supply &nbsp;
Mention SOGI &nbsp;
1-888-885-3500 / (617) 776-2978 &nbsp;
~$25 total!

The only way that I could help with a manifold is by giving you my s14 header, if you have an s14, and letting them cut mine apart and weld on to it saving you downtime vs. using yours. &nbsp;But RH manifolds are $400+
If you're looking at a t3/4 from a grandnational, you should really think about boosted's. &nbsp;You dont know how the GN was taken care of, and how many miles, but I am sure boosted know everything about his turbo. &nbsp;But its not internal wastegated.
Turbo Timer. &nbsp;
Build Your Own Turbo Timer (Have good knowledge of Electronics.)
$30.00 turbo timer with 20 hours remaining
But yeah, check ebay for cheap electronics. &nbsp;Like I paid $113 for a $160 turbo timer there <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=''>
Anything else?

[sykikchimp]

$550 is more than I want to spend on a turbo, otherwise I Probably would pick it up.

I need a manifold.. &nbsp;ugg.. &nbsp;I read some really crappy stiff about the revhard off FA so I think I might try to stay away from that..

Thanks for the other info too! &nbsp;That helps.

[rotaryknight]

If you are gettin a A/F meter donot get the Autometer one....it's just a bunch of moving lights.

The only A/F gauge that is worth buying is the Tomei. &nbsp;It's truetime analog so you can see how your exhaust gas is really moving...how fast it gets to lean.

This is comming from a FD owner where a/f is way more important than on any other car.

Yeah. &nbsp;A few people have had it crack.
When I ordered my turbo and manifold from DA, they said that there was a backorder on the revhard manifolds, because they were redesigning them. &nbsp;I have seen pictures of the old manifolds, and mine, and mine seems to be a lot thinker, and not as large. &nbsp;
And I was thinking about how they crack. &nbsp;It seems really hard to. &nbsp;They are cast iron and one-piece construction. &nbsp;And 7 psi isn't really too much pressure. &nbsp;I can hold my finger over my friends boost controller line, which is 8 psi. &nbsp;And it doesnt take ANY effort at all. &nbsp;So I really don't know. &nbsp;Perhaps they were running lean and heated the manifold WAY up then it got splashed with water or something and cracked. &nbsp;I just don't know, but by the looks of mine, it will be with me for a while.

[s15dude]

I'm not sure how much it will cost (around $200-$300), but my dad and I are going to make a log style manifold for the DOHC motor. &nbsp;After I am done with school (may 15th), I am going to start working on this. Custom flanges should not be that hard to make, I will keep you all updated in the next few weeks. If someone near San Diego has a SOHC car and needs a manifold, we could do that too, but you would need to come to our shop so we could make a templete from your stock exhaust manifold.

[sykikchimp]

http://www.jgstools.com/turbo/thk.html

Its a Log manifold kit .. Seems like a better/cheaper alternative to a Revhard. &nbsp;Just have to find a welder..

[s15dude]

Thats pretty much what I plan on making, but I will be making all of the componets myself. Cool info though, I would recomend going to a highly skilled welder for that, cuz if you don't do a good job, the welds can crack/break.

[Jeff240sx]

Thats basically what the new revhard manifolds look like. &nbsp;The finished part. &nbsp;Anyway... good luck sourcing the parts... and keep me posted on it, either AIM "Sleek S14" or PM.

So I'm presuming you also replaced your O2 sensor with a wideband one, and a compatible controller? Cuz that's the only way you're gonna get more accurate readings.

[sykikchimp]

I've heard that a Voltage meter can actually tell you a much more clear picture than an A/F meter
