So here is a possible list of components for my turbo setup. Keep in mind that I am entirely a n00b at turbos and am open to all suggestions.

~600$ Turbo T3/T04e 50 Trim~500 Manifold (not sure which yet) log or tubular?~119 Walbro 255 fuel pump~250 Deltagate Wastegate 35mm (EDIT: or Tial)~427 HKS BOV~404 ($101 each) 550cc injectors~300 Greddy Profec boost controller~300 Apexi safc ~430 spearco intercooler

I will need all of the oil lines, all of the piping/hoses/fittings and a downpipe as well... but this is a rough sketch of what I may be looking at.

I would like to pull somewhere around 250 - 280 on stock internals for now. In the future I would like to go with more boost on a built motor, but that is far in the future. So what do you guys think? Realistic? Stupid?

Any reason in particular for the tial over the deltagate? I actually didn't choose the deltagate for any reason. It was more that I didn't know of much of a difference so I just chose one.

The Deltagate creeps and the Tial is cheaper.

deltagate is known to creep. pos stay away. which hks bov are you buying thats $400? is it made of gold? and to be honest with you if you wanna go cheaper you can. buy used parts. theres nothing wrong with that at all. i would buy the turbo new but thats it. a GREAT place to seek deals is over on http://www.honda-tech.com check out their forced induction classifieds section. thats where i get most of my stuff from.

j-z yeah after I posted that I realized that I could find an HKS bov for much less. I guess whatever site I was reading at the time listed it for about 400. i think I can get it for nearly half that.

When I actually start putting the kit together, I will probably buy used stuff. I wanted to give myself an idea of how much money I would be saving from putting together my own kit as opposed to buying one.

~600$ Turbo T3/T04e 50 TrimEbay, t3/t04b would be better suited for your application probably, of course that would depend on the turbo. But you can usually find them for 300-500 dollars, might save a few dollars. Then again, if you can afford a new one, its your best bet. That way you know what you are getting. Might be wise not to skimp on this one.

~500 Manifold (not sure which yet) log or tubular?tubular. jgstools log style, 230 or so on sale right now.Add 30 bucks to get the flange welded, so maybe 260 or so. 240 saved.

~119 Walbro 255 fuel pumpI got mine for something like 90 shipped off ebay, so thats 20 saved.

~250 Deltagate Wastegate 35mm (EDIT: or Tial)Tial 38mm off ebay is 230 dollars, thats another 20 saved.

~427 HKS BOV

HKS SSQV BOV off ebay is 175 dollars, so thats 250 dollars saved

~404 ($101 each) 550cc injectorsThats not a bad price, but you can often find 550cc nippon denso side feed high impedance RX-7 13B primary injectors for cheaper

~300 Greddy Profec boost controller

It would be nice to have an electronic boost controller. You can a profec B off ebay for around 200 dollars usually, but for your modest HP level I think you could probably get by with a decent 30 dollar MBC. So thats a minimum of 100 bucks cheaper, possibly more.

~300 Apexi safc

Thats about right for an safc2 off ebay, somewhere around 250-300 bucks.

~430 spearco intercoolerNow this one is too high... You can find a nice core off ebay for 250 bucks- that will get you a pretty darn nice unit, especially if its only supporting 300 hp or so. Thats another 150 saved.

Total that comes up to 680 by my addition (I'm bad at math so any errors, sorry) and with that money you can get your downpipe and intercooler piping, and probably still have money left over for MSD BTM, a wise investment.

Good points in andrave's post. if you want a centralized control point, you may want to look into getting an e-manage. it'll do your timing - no need for the BTM then. Add $200 to the SAFC cost for the E-manage with harnesses and support tool.

Or, you could add a Profec E-01. Mohdparts has this deal:

E-manage + Profec E-01 + ignition & injector Harness + PRofec E-01 Pressure Sensor Harness = $847

For ~900 bucks, you've got fuel, ignition, boost control, great monitoring, datalogging, etc, etc. that setup should take you to the 350 range, then you should look at standalones. but i'm sure you could sell the e-manage/profec system to another person when you're done with it.

i got my hks ssqv for 183 shipped off ebay from autowurks and hes a great guy. i've talked to him alot and he said they get great prices and might be wiling to do some group buys for us. but remember u also have to get the $60 steel flange and the $20 recircualtion fitting unless u do a blow through maf set up.

or i have my bosch bov that came with my nsport kit that ill sell for like $25 shipped

andrave- the rx-7 injectors are cheap but dont drop right in so u have to buy extra lil parts, nothin major, but still extra stuff to make them not leak.

everythign else people are saying is good especailyl about the boost controller

Hey guys, thanks for the replies. With my initial $$ estimates, I was below the cost for any of the kits out there. Now, Im significantly below. Thats pretty nice. ;)

However, being new to the electronics instruments for turbo applications, I am getting confused as to how these different pieces work together.

So, an E-manage piggybacks a stock ECU or a JWT ECU right? and makes a BTM unneeded? But is the BTM the same as a profec unit? And an safc will be not be needed if you have a profec? oh jeez, im confused.

profec is a boost controller, an electronic boost controller. Thats all.

E manage is a piggy back engine computer which can control timing and fuel maps, so it takes the place of BTM since it can control timing, and it takes the place of the SAFC, which is a fuel computer.

With e manage you will still need some sort of boost control unless you opt for the E01... and that deal jonny posted make that hard to resist, since a greddy boost controller, an SAFC, and msd btm is something like 200+300+150 or so, and then you would have all the controls in car with the E01.

could be a neat setup.

Andrave... thanks for the enlightenment. That makes things clearer in my mind. That mohdparts deal does seem nice.

I think ultimately I would like to hit a very reliable 300 hp. Im not interested in hitting the huge power levels because I want a reliable daily driver. However, smoking mustangs and camaros is on my wish list.

I will end up building the motor some time down the line to achieve the 300 mark. For now, I would be incredibly happy with 260 to 280 hp.

well right now I think you should decide to stick with something that you can grow with. If you get an SAFC2, you probably are going to end up having to change to a different management system once you decide to go for more power.Of course, if you decide to hack the mafs later, the safc2 could give you some adjustments.

As it stands, the emanage has the capability to control more and grow with you, but there have been plenty of people to make big power on msd and other fuel controllers.

Ok, so in your opinion, an emanage coupled with the profec e01 would be a pretty good setup and could take me into 300's with no problem?

I think that this is an expensive route, but probably well worth it in the long run.

I'm going with the Support Tool instead of the Profec E-01 for programming on my e-manage, but believe me - i'd rather have the Profec :D.

The only reason I choose the support tool instead is to save a little money now, since I already have a laptop, and I won't be running over the stock WG spring for a while anyways (.4 bar).

300hp will be cake for the e-manage. like Mohd Parts mentions on their site, there are Supras running upwards of 5-600 hp on the Greddy system. I believe you're looking at roughly 12-14 psi depending on situation for that; a good wastegate and the E-manage/profec will rock. 550cc injectors should be sized OK for the 300 range.

I'll agree that the price of the e-manage package (even the cheapie i got) kinda gave me pause when I looked at it. but i realized that yes, some stuff will be big-ticket items.

I'm just really glad that electronics aren't a 'wear' item. Properly installed, they should last forever, in theory. I'm counting on being able to pull my piggyback system and throw it on whatever car I get next, after the 240 gets a Tec3. :D

Yes this is true. Electronics such as these will last for a long time. I have been looking on ebay and you could actually get the profec e0-1 for 500 and an emanage for around 150... not too shabby.

you found an emanage for 150? dare I ask, where?I've only seen them as low as 250 plus shipping or 275 shipped... and thats with no harnesses (keep that in mind).I only need one harness, for ignition and injector control, and the support tool.The harness is no problem, since I have seen them pretty cheap, but the support tool, some guys want 160 bucks for!I'm hoping to get a package deal on it.

Well I found this:http://cgi.ebay.com/ws/eBayISA...50138

and this used one:http://cgi.ebay.com/ebaymotors...59615

Not too bad. The first says that it comes with the support tool as well.

if youre only shooting for 300 whp an afc will be able to handle your tuning. there are plenty of honda guys just using an afc for fuel tuning. you can pick a used one up for $200. this is the route i will be going to hit my 300whp mark. but if you plan to go higher later down the road you might be better off getting the emanage.

yes but AFC doesn't allow you to adjust timing.. and you can get a new e manage for 250 bucks or so...
