Rep Power: 374

Ok, I'm going to start putting together a turbo kit. I haven't really decided though on what I'm going to do fuel wise. I was just thinking about getting the SF fuel setup. But later down the road I plan on building the bottom end and turning up the boost. So What else would need to be does to the SF fuel system to run high boost? If I remember correctly the SF fuel system is good for 12psi correct? Then you would have to upgrade the fuel injectors and fuel pump. But is that all? I really don't want to do a return style fuel setup. I'm putting together my own kit so I can save some money.

Heres what i'm looking at getting.

HKS Manifold
T3 or T3/T4 turbo
Greddy type 24 front mount intercooler
Tial 35MM Wastegate(not sure on what size spring)
Oil lines for turbo(not sure what to get though)
Custom down pipe
Custom pipping
HKS SSQ BOV


What else should I get besides a boost contoller, gauges, plugs, and a turbo timer? Does this setup look good?

I really don't want to order a kit, due to it taking 3-4 months to get.

Without a flange you can't fit a T3 on an HKS manifold, the HKS is made for a T25.

^^^^Thanks for the info on that. I thought that it was made for a T3.

Would the SF fuel setup also work good on build NA blocks? I mean also with bigger fuel injectors and fuel pump but it would be some what necessary right?

Dober is right. You'd need to re-flange the HKS Manifold for a t3 or t3/t4. But if you dont want to do that, you can always use a T28 turbo. The T28 will fit fine.

Jodster the oil lines that you would need or SHOULD get are steel braided lines. Don't forget you'll need fittings and couplings too. And you'll need a dump tube as well if you're goin external wastegate.

As far as fuel goes there are your basic two options and yes, from what I understand alcohol injection is used on race cars that achieve even higher levels of boost.

But IMHO I would like to upgrade the injectors eventually. There's just somethin that bothers me about havin 200 odd CC injectors on a turbo application.

Someone correct me if I'm wrong, but don't FMU's increase fuel based on the increase of boost? If so....then an FMU would not be needed on a naturally aspirated car. You can, however, convert the fuel system and use a fuel pump and fuel pressure regulator along with an AFC. But I think on an N/A car....the FMU would be unnecessary.

FMU=Fuel Management Unit? I dunno? I am Lost on the whole fuel system, I know I am getting the SAFC II but as for the fuel management stuff, bigger injectors....sounds good. LoL.

you are right! You know your stuff.

^^ cool.

So there's your answer Project2k2. An FMU (fuel management unit like u assumed) like the one SF offers wouldn't be necessary on an N/A car.

Ok so the HKS uses a T25 or T28 turbo. I'm just trying to add it up and see if if i sould go custom or order a kit.

go custom... do a return line setup of 300-400... still cheaper then Sf's system 500+ .

try' OBX's manifold.. it holds a t3/t4 flange i believe and it is also ready for an external wastegate.


AND you can buy Oil Line KITS ON ebay for about 60 bucks which include all the hoses, flanges and fittings for your oil feed and return.

also everyone seems to think that a bigger turbo is better.. but its all preference. i prefer a smaller one due to fast spool up. people will state that the smaller turbo's HP dies off at HIGHER RPM's and boost levels...
you drive a SOHC 1.7 .... a T25 is MORE then enough IMO.



back to ur questions.. weither u go SF or return ... if ur gonna turn the boost up high...sooner or later ur gonna need bigger injectors. get them sooner.

Who makes bigger injectors for us? I thought that you had to custom fit bigger injectors into our fuel rail?

A small turbo would be fine with me. I one day would love to build the motor and turn up the boost, but whos to say that I will end up doing that. For all I know, after I boost the car I might want to keep it like it is.

So if I get the HKS Manifold and a T28 or say a 16G turbo the SF fuel kit would do fine? I really don't want to do all the work on doing a return fuel style. And I don't think I have the no how to do so. I have seen the oil line kits on ebay.

Next question, should I get a turbo with an internal or External wastegate? Also, which kind of turbo should I get? One thats oil cooled and water cooled? Or just oil cooled?

Well...officially no one makes aftermarket injectors that "fit right into" our fuel rail. If you want RC's, DSM's, etc etc....you'll need to customize the fuel rail. (simply because they are too tall and will cause the fuel rail to bump heads w/the TPS) Or you can try and find other cars (like the STi) who's injectors are similar in height and size to ours (but they are +/- 550CC's so you'll need hondata, or emanage to trim the fuel).

You can use a t28.....on the HKS Manifold. It's simply a T25 Turbine with a T3 Compressor. Anything other than a T25 or a T28 you'd need another flange.

Most small turbos do just fine with an internal wastegate. But if you do decide to go with an external, you will need to flange that on as well. Again though, on a turbo the size of say a t25 you really don't need an external.

Small turbo for the 1.7, like OSOBOOSTED mentioned are fine. The difference (which he mentioned) is that the smaller turbo (although it spools quicker) will eventually stop making [more] power top end. Whereas the Larger turbos (although the tend to lag more/take longer to spool up) will make more power top end. But this is why hybrid turbos exist, and turbo lag can easily be cured w/n2o.

However, if you don't plan on making outrageously serious power (which you prolly wont unless you build that motor), I don't see why you shouldn't just stick to a smaller turbo. The t25...like they mentioned, is just fine for your application.

Edit: As far as "what kind" of turbo to get, I'd just go with a Garret (aka Air Research) turbo. There are plenty on Ebay and online in general.

Thanks again guys. Ok, now should I stick with the SF fuel kit, or get something else. I dont' really want to do a return fuel line.

Well then. You just answered your own question. If you don't wanna do a return fuel coversion, then an FMU and alc. injection is your answer.

 
Rep Power: 374

Do I need the Acl injection? I just plan on running 6-8 psi for now.

No.

hmm... how much are u willing to pay? maybe ill just do a return.

No you don;t really need the alc injection, but that's part of what SF offers regarding fuel management. I'm sure you can skip out on that option though. Before you do....read the post about alc. injection and make sure it's what ya want/dont want.

You want to sell your SF fuel setup? Give me a figure and well talk.

honestly im deciding weither or not to go return... its gonna cost alteast 400 to do so . so id need alteast that... plus SF sells the fuel system for 600 new so i duno.

i gotta talk to alex(boosted2k2) and see whats up with the return.

-8 feed and a -6 return line. i'd be happy to give specs if anybody wants them.
