Need Help with Turbo Upgrade

[CBGuamRealtor]

First off, I'd really appreciate any help and advice offered.

Just swapped in my S14 SR20DET into my Zenki. My stock turbo is blown...sounds like a helicopter except with a high pitch grinding noise.

I am considering a turbo upgrade. Considering the GT2871R (leaning more towards the .64.) Any other turbo recommendations that will not require too much fabrications is appreciated.

*Which actuator will be most reliable for DD? RS / R / HKS?? Or any other recommendations/advice?

Purpose for car and expected HP range: Street/Drift ... Reliable DD 350-400hp on pump gas. (Turbo must not only be responsive in the mid-range but also has to have good top end power.)

I am looking to include injectors (550 or preferrably larger), fuel pump, fuel pressure regulator, and Apexi NEO. ECU will be on the future mods. Depending on availability of tuners in my area.

I apologize for such a LONG post but I want to be as detailed as possible with my build... here's my part list...I have a pretty conservative set up...please no flaming.

My parts so far:

ENGINE:Z32 MAFTomei headgasket Tomei rockerarms stopperHKS SSQV (older one i think)Greddy SPL (?) FMIC KOYO radiatorHKS actuator off my stock turboGreddy 08 platinum plugsTomei exhaust manifold?? with heat wrapGreddy Hot pipe (on the way in)

SUSPENSION:TEIN inner/outer tie rodsTEIN tension rodsTanabe front/rear strut barsSway bars (I forget the brand) Suspension Techniques? neon green colored.Full poleurathane bushings kitPoleurathane Subframe bushings (on the way in)Cusco Zero II (on the way in)

VLSD 5-lug ConversionGT-R 33 4-piston front / 2-piston rear brakesSteel Brake lines (on the ways in)S14 4-piston brake master cylinderNISMO underbrace (on the way in)

PARTS NEEDED IMMEDIATELY:-TURBO and necessary items (injectors, fuel pump, APEXi NEO (Buying off a friend for $360) and fuel pressure regulator.-Electric fans (3000 CFM minimum/ 12in)

Anything major I'm missing or forgetting??

FUTURE PARTS LIST:-Clutch-Other arms (rear camber etc...)-ECU-CAMs (notch top compatible)

Again, I apologize for such a long post but I really need to get my car running....over 10k in and still down. I truely appreciated any help/advice offered.

Thanks

550cc's are max on any safc so you might reach 400whp on race gas and 300ish whp on pump gas. I use altima dual fans and only turn on 1 becouse it will over cool my coolent ! For street/drift your right the gt2871r will be my next turbo! 64 a/r becouse its better to have 30 more foot pounds of tourque now than 20 topend hp later!

[CBGuamRealtor]

Would larger injectors still work with afc's? Just in case I wana upgrade to a stand-alone ems in the future.

Ive heard that SR's are prone to overheating...whats the standard fan specs?

Weather where I live is on average 85F year round.

I agree that the GT2871r may be a good turbo upgrade. I have yet to find out tho. Is this one of the those turbos that you quickly outgrow?

[CBGuamRealtor]

Does anyone know the difference between the HKS, GT2871R, and GT2871RS??

HP and torque numbers with the HKS turbo?? Price range is around the same with the GT2871R...what are the differences beside brand?

HKS GT-SS Turbo Upgrade S14/S15 SR20DET

Thanks ahead for any input and info.

******EDIT: Anyone using the Cusco Zero2 for the S14?? Will they accomodate street/drift purposes?? thanks agn

550cc's are max on any safc

any more and it wont be 100% fuel tuneable. If you can blow $1420 on a turbo maby you should look into a apexi power fc or stand-alone ems due to alot better tunability !

[CBGuamRealtor]

Yeah, did a little bit of homework on the Apexi Power FC...I agree this may be a better way to go for the long run with bigger power in mind.

Unfortunately, I only have a $4k budget to get the car at least running.-GT2871R .64 with HKS actuator $1400-550 SARD $600-Fuel pressure regulator and pump $300-Cusco Zero 2 RE $1800-Apexi Neo $360-Thermo stat ????-Electric Fans ????

I will purchase all these parts within the next week or so. I have a friend who will be going to Japan to bring back all these parts except for the GT2871R. PLEASE LET ME KNOW IF ANY OF THESE ARE OVER PRICED.

Thank you

As far as SRs being prone to overheating. That's really not that big of an issue on a daily. During long, high RPM issues, the pump can cavitate a bit. But so long as you have a good radiator and good fan setup, you should be good to go.

I personally wouldn't spend the money on the cusco struts. You can get KTS coilovers from SPL for about 1100-1200 and they're are the best deal on a great performing coilover out there.

Th price on the 2871 and HKS actuator sounds about 100 too high to me. Most places I see the turbo going for 1200-ish and the actuator should be $95-ish.

Get deatschwerks injectors. They are some great injectors and won't break your bank. If you're overly worried about price, go with top feed style. JGY makes a top feed rail designed specifically for the SR intake mani. You may want to double check if it will work on the S14 mani though.

I was unaware that there was an RS version of the 2871. The S usually denotes that something special is on that turbo that requires some kind of annotation.

[CBGuamRealtor]

Thanks for the advice. I will look into KTS coilovers. I currently have a single e-fan on. I hope it can do its job, I'll have to keep a close eye on the engine temps.

I may be wrong with the GT2871RS but I think you answered my question tho. I may have mixed it up with the GT-RS by HKS?

Thanks for all the advice so far and I appreciate everyone's input and help with this.

I think hes talking the T28 style compressor housing 2871R. Deatchwerks is a good company for injectors. Ive been running them for a couple years now. Dont waste your time with the SAFC. At least get an Enthalpy or JWT ECU tune if not a standalone.

[abubika345]

I saw that you had clutch on your future mods. I would get that when u get the turbo. Go with a good 6 puck (a tad harsh for street use but i love the feel) I have a competition 6 puck and for the price its taking quite a beating and is still like brand new

[SleepR 240sx]

In my opinion an SAFC won't cut it for that kind of a setup. You need to be running at least a ROM tune. Preferably dyno tuned by someone who has experience or a standalone system. Tuning is what makes and brakes the motors. Sure you can run the SAFC and the car will run, but you'll be doing yourself a massive favor by getting a real tune. Save money later by doing it right now.

Other than that, I think 740cc injectors would be good for that kind of a setup. I think you'll be maxing out 500's sooner than you think, and if you ever want to raise the boost you'll have some room with the 740's.

You better have a clutch that can handle the power your talking about as well. Stock won't cut it. At least a stage 2.
