A bit of help and input please..

[toki]

Ok, I've realized I don't and wont have the money for an engine swap anytime soon, so it looks like I am going to just try and run a budget KAET here....so here is a list for what I think i'll be needing?

T28, T3, or T3/T4 Turbine - I'm sure i'll find one on eBay for under $400 (would the DSM T25 work for low boost, i'de say 7psi tops?)

Turbo Manifold - I really have no idea where to go to get this made, the only custom fab shop I know of in AZ sucks, and botched an order for an exhaust manifold for my friends KAE that took 9 weaks to get delivered.

Intercooler off a junked Volvo/Supra/? - Which is the best, which will be the easiest to work with, etc?

Walbro 255lph fuel pump - (This guy has them on eBay for $100 shipped, sounds like a reasonable price to me http://cgi.ebay.com/ebaymotors...33555)

Intake piping - Ok, i've been researching turbos for a while, but i'm still in the dark on how the plumbing actually works, so I dont really know if the intake piping replaces the engine intake, or if this is a seperate one, but from what I hear..you need one.

Downpipe (hotpipe/testpipe?) - are these 3 names for 1 thing? Could an exhaust shop fabricate one of these?

Oil (and water?) lines to the Turbine - Ok, again, I know how turbos work in theory but not in practice, so I dont exactly know where these run, but i'm sure i'll need them....how about a place to get them also?

Z32 MAF? need one?

Bigger injectors? need some? remember only 7psi tops here for now..5 is more realistic

Are there any other misc things i'll need? Flanges and such? I hear something need to be done with the throttle body?

I've been trying to pick up a copy of maximum boost so I dont have to ask all these questions, but not a single book store i've been too carries it, niether does our public library...I guess maybe I should just order one if you think i'm just too in the dark right now to plan/complete it? Thanks for reading the horribly long post and any help you give me.

wow, where do i start! well most KAs are running either the T04Es or the T04B most Es are running a .63 A/R and 50 or 57 compressor trim.fuel pump is a must.piping- all stock intake piping is replaced. u need a intake pipe feeding into the charger, then a hotpipe feeding from turbo to intercooler, than a cold pipe feeding from intercooler to throttlebody. its called a hot pipe cause its carrying hot air from the turbo, its called a cold pipe cause its carrying air that has cooled down through the intercooler. a test pipe is a tube that replaces a a cat which is strait through, allowing alot more exhaust flow. a downpipe is the peice before the cat or testpipe that leads from the exhaust side of the turbo to the cat or test. alot of the stuff i didnt not answer cause either im not sure or depends on they type of fuel management ur going to be running, figure out which way ur going to increase ur fuel supply and i can answer some more questions

[gyfer]

First, you need to find a turbo manifold and a turbo.http://www.jgstools.com/turbo/ sell a manifold for KA24E.Then you need to decide how to find fit the turbo into your engine compartment. ( Should your A/C still be there... mine is.)and your wastegate too ( if you plan to run external wastegate)

Then get a intercooler. Fit into car. Make sure your can put your bumper on.

Unmount your bumper. Start building your intercooler pipe. Is better off asking your friend to built it on spot. I don't recall anyone building a kit for us.

Make a down pipe ( from your turbo to cat, if no cat, to test pipe). I like my car to be quiet, so I route my dump pipe (after external wastegate) into down pipe.

After all piping is done, then you should start hooking up all your electrical and fuel stuff. Boost gauge, EGT, piggy back/ Z31 MAF / FMU ... blah blah.

I will hook up FMU, piggy back before all turbo installation, to make sure it works, and less thing to think "what the hell goes wrong" if your car won't start or idle. ( like mine.. )

Tips: if you look at your intake pipe ( the C-shape plastic ), just before the throttle body, there is 2 hose connecting to the pipe. The biggest one is your "air source" for "idle control valve solenoid"... you can't draw the air from atmosphere... it must taken after MAF. It took me 2 days to find this out. Oh yeah.. my KA24E is boosting now.. babe

Check out http://www.mostreetracing.com/forum under imports tech section. I posted some pics there for my turbo proj. Yes.. the piping is beautiful..... just put the bumper on last night. Will wash the car today, take some photos, and post it here. Don't be afraid to ask me if you have any KA24E question... I've been there...

[gyfer]

26 hose clamps from hardware store : $40 dollar10 U-pipe 180degree for auto store: $200 dollar8 rubber hose for connecting IC pipe from online store : $60 dollar30 foot of vacuum/water/oil line : $50 dollarHaving a boosting 240 KA24E : priceless

[toki]

hah yeah.

gyfer, could I see some pics of under your hood? I need to keep PS and A/C, and i've obviously never done this before so I wouldn't know how to place it..

[gyfer]

It took me looooong time to adjust the flange to fit the turbo the way I wanted. I have 1/2" clearance to a/c pipe ( near the pump ), 1/2" to a/c rubber hose ( I have to lower the metal hose on firewall ), 1/2" to steering rod, 1" from brake pump, and less than 1/2" from transmission due to my 3" downpipe.

You don't have to "done this before" to know where to put it. Get a turbo, and manifold, then try to find good clearance for it.

[toki]

heh, make it sound so simple.

As far as fuel goes, at what psi would I need to get some kind of piggyback for my ECU, or a JWT ECU (how much do these cost, I emailed them once for a quote but no reply?)

I'm thinking 550cc injectors would be the right size for 7psi?

[TurboKA37]

SAFC will go for bout 300, i believe the jwy runs about 600, and if ur only running 7 psi and dont plan on upping the boost anytime soon id go with 370cc injectors(remember Nsport kit runs 7psi on stock injectors although they are at a pretty high duty cycle) i think 370cc should be good up to 10 psi and can be bought for a couple hundred depending on manufacturer.

[toki]

would the 370 vs the 550 have any different outcome on emmissions? Atleast i remember bigger injectors being a cause or selling point on people not passing emmisions?

[Nathan]

You can get 370's much cheaper than that if you dont mind used...I see SR guys selling them for around 80 bucks all the time Or you can use them from a 95-96 300zx apparently My plan is to retard the timing about 2 degrees, run an S-AFC II, up the base fuel pressure a little bit and use a 1:1 rising rate regulator with 370cc injectors. I have no doubt that I will be able to run around 10psi with that setup and put down horsepower in the mid to high 200's

[TurboKA37]

i concur, i plan on doing a very similar set-up

[toki]

http://cgi.ebay.com/ebaymotors...33742

The tiny DSM intercooler, would this easily fit into the stock bumper and would it be any trouble to get hot/cold pipes fabricated to run to and from it? And would it even be worth getting, but remember low psi, 5-7...

[TurboKA37]

hehe did u see the side pic of that intercooler with the ruler?? they tried to trick ya buy holding the ruler up right in the middle of the ruler

[toki]

lol I dont think they were neccisarily trying to trick people...BUT ANSWER THE QUESTION RARG.

Edit: what about this turbo for low boost? http://cgi.ebay.com/ebaymotors...33742

I am an eBay WHORE...

[toki]

HELLLLLLLLLLLLLLLOOOOOOOOOOOOOOOOOO?!

[Stan-O]

Z32 MAF? need one?

Nope, Even with a JWT ECU they only program for the Cobra MAF for the KA

Stan-O

[Nathan]

I know someone running a 300zx maf with a JWT tuned ecu...so evidently they CAN tune for something else if you want them too.

[TurboKA37]

are there any MAF that can replace the stock 240 MAF without ecu tuning?

[toki]

how about this, since me previous question was vauge:

Do I need a new MAF (such as the Z31/32) with the boost I will be running? (5-7psi), or will my stock MAF be ok?

[erich]

The stock MAF and 370cc injectors run out at the same time, about 260 crank HP.I use a straight T3 from Turbonetics, 60 trim compressor, .63 A/R turbine with BB center section at 10 psi. I dyno'ed at 224rwhp which is about right as 224x1.15 for drivetrain loss is 257.6 crank hp.

only 224 rwhp at 10psi!!?? r u not running an intercooler? the nsport kit runs 7 psi and that has seen results of up to 240 rwhp.

[erich]

Of course I'm running a FMIC. That's what you should get on a corrected, calibrated dyno. I might be getting a little bit more (maybe 5whp) now because I had the idle air sourced from pre-turbo which give me a boost leak. That has been fixed and it feels a little stronger, but not much. You won't get 240whp with 370cc injectors unless you run at least 4 bar fuel pressure. There just isn't enough fuel.I always see people saying "I just dynoed 240rwhp at 7 psi" and I think they (or the dyno) is full of it. Seven psi is about 50% more air in the cylinders which should give you about 50% more power, assuming that the volumetric efficiency and air density hasn't changed (which it does under boost.) but since the air density is LOWER after the turbo due to heating and the volumetric efficiency is HIGHER due to boost it evens out pretty well. If you get 240whp on 10psi then OK, I can believe it with a better I/C and more efficient turbo.Just remember there is no difference between in 10psi @120 degrees in the intake plenum from a T3 or a T04E, a volume of air at the same pressure and temperature is equivilent no matter which turbo it comes from.

[TurboKA37]

i guess so but ive seen claims of up to 300 whp at 12 psi of boost on stock internals. of coarse he had an upgraded cam and some pulleys and such but 224 whp at 10 psi just surpised me after seeing so many people claim more hp with the same or less boost

[toki]

It's all about the tiny DSM intercooler that I posted up earlier, and no one commented on.

And instead of actually getting hot/cold pipes made, why not just use of those custom intercooler piping kits?

[gyfer]

toki : You should go bigger Intercooler. Is just too small :-)I will recommend a better fuel control than just a FMU after 5psi.

[toki]

but am i going to be able to find anything normal sized for cheap. I was trying to keep this under 1k, but a big intercooler could easily through it over that by alot...

[gyfer]

I have a saab intercooler.. cost me $100 ebay. Lot bigger than eclipse stock.. ( heard it doesn't flow as good... hey, boost it up then.. lol )

but fabricating the pipe for that IC is a bi.tch.photo here: http://www.mostreetracing.com/forum , look under importtech, smilling face thread.

[gyfer]

Seven psi is about 50% more air in the cylinders which should give you about 50% more power, assuming that the volumetric efficiency and air density hasn't changed .... Just remember there is no difference between in 10psi @120 degrees in the intake plenum from a T3 or a T04E, a volume of air at the same pressure and temperature is equivilent no matter which turbo it comes from.

I am TOTALLY DISAGREE with your statement.In a static air ( no movement ), yes, 7psi ( ~= 0.5bar) should give you about 50% more air VOLUME in same space. But we are not talking about statir air here. Air in the intake constantly moving. The PSI number is to show more air is "pack" in a same flowing air. You have to put FLOW into consideration. That's why Turbo is category into different CFM and efficeincy ( how much heat generated in the process of compressing air ) at different psi.

If above theory can't make your feel confinced : Is the 1.5" IC pipe make same HP power compare to 2.5" IC pipe , at same psi? Don't sound like it should.. right ? Why ? because it flow different.. yes, is flow that make different

And also, 50% more air DOES NOT mean 50% more power. It never apply, and never will. ( if it does, hell.. why are we learning physics for ? )

[gyfer]

toki, you have a HB ?

[toki]

Yes
