I just ordered 2 t3/t4 turbonetics 60-1 hi-fi turbos the other day to go along with my SFR TT kit (this is going on my Z) . Now i am kinda wondering if they are going to spool to slow for my taste. I went with them due to the fact that they were recommended by the kits designer, but these suckers are big for a twin setup (capable of over 1100whp big!!). Any opinions?

BTW i ask this question here because 90% of the people on my350z are idiots. The ORG= tmfw

 

If you wreck your Z I call dibs on the engine/tranny/brakes

Whats your HP goal? Most guys seem to be breaking alot of parts at the 500-600WHP range w/o built engines. Then again I've just started looking at the better threads at my350z.

Seems like you bought some pretty large turbos. I hope you've got a built engine waiting for them!

I wouldn't have gotten the SFR kit but that's just me. There's no point unless you are planning on making over like 700-800whp which I doubt. I've got quite a bit of experience with 350Z turbo kits, I've worked on and driven a number of turbo 350Zs APS twin, greddy twin, aps single. The power with the APS and greddy twin kits is instant, and I do mean instant. With the SFR kit, it won't be.

Sounds like a moot point though since you've already ordered it.

 

Thanks for the input guys,

I got the kit from Julian@MRC. It had everything required except:EMS, Injectors, Turbos, Wastegates, BOV, and intercooler. After getting everything it still ended up being cheaper than the greddy and APS kits(about 1000-2000 dollars cheaper). Also i got to choose all the parts i wanted which was something i couldn't do with the greddy kit. I really wanted the greddy kit for years but i would have ended up replacing alot of the parts that are in the kit.

I'll eventually end up building the motor, but that is not in the near future

 

Wait, so what WAS included in the kit, just the piping lol. How much did you pay and what components did you get for EMS, injectors, wastegates, etc.

 

I would think twin T3s would be what you would really want without going to the more expensive GT series turbos. I will be interested seeing how it turns out with the T3/T4s though. Considering that is what most VQ30 people used with a single turbo I just think it will be too big for your taste.

BTW do you still have those cam adapters. I need to start on the 240 soon.

 

I think it was mostly the manifolds and some of the piping. I think he only wants about 400-500whp. Something streetable, but he will probably change his mind once he gets it together and starts boosting.

 

The manifolds, all the necessary piping, wastegate dumps, oil sump pump, oil return and feed lines, all necessary fittings, clamps couplers, and hardware.

For all that i paid $1800 shipped.

As far as the rest of the kit i have:
Utec w/ map sensor and boost control solenoid (had it for months now just never installed it)
Getting DW 650cc injectors (care to give a discount )
Walboro 255 ($100)
HKS SSQV BOV ($175)
2 Tial 38mm wastegates ($400)
Turbos ($1700)
Down pipes ($400)
Intercooler ($1000)

Counting the price of injectors brings the total to $5975

 

That's a pretty nice price, I hope the slower spooling doesn't bother you. I don't have anything to do with deatschwerks, I just help mike promote his product because he's one of my good friends and it's a good product. talk to him about pricing.

 

What kind of $1000 intercooler are you buying?
Where are you buying a $175 HKS SSQV?

 

I hope it's not an ebay knockoff.... tests have shown that they leak.

 

Got the bov from a sponsor on my350z. The intercooler is a sfr intercooler with a spearco core.

 

good lord that's an overpriced IC... if you didn't purchase it yet I'd think again about it.

 

i am ordering it next week. I looked around and it is hard to find something that matches it. It has a vertical draft core with the inlets on either side of the bottom and the outlet on top.

 

you should contact bell intercoolers and see what they'd charge for a similar setup. it might not be cheaper but it can't hurt to try. their stuff is top notch and they will do any crazy custom shape you can imagine.

 

Why the hks ssqv? If your going to get a valve that is not able to be recirculated, why not get the tial 50mm unit?

 

thats what the charge pipes are already setup for. It already has the flange welded on.

 

If he was SC like his Maxima then yes a TiAl would be a lot better, but there is nothing wrong with a HKS SSQV for his setup.

 

Wow I thought I was the only one that thought that.

 

First, are they T3/T4 or 60-1's?

60-1 HiFi is a T4.

If they are 60-1's, The spool on those is going to be terrible. Turbonetics uses that turbo for thier single kit. 2 of them should spool around 5000rpm. That may be a slight exageration but not much.

 

Hey Chris, Just because it is the cheapest setup does not mean that it is the best setup for you.
It might be worth it to spend a little more for a setup to get something that is more reliable and produces more efficiant power. Don't cut too many corners and end up with something that you regret doing again.
Do I need to remind you of the Maxima?

 

Aside from the choice in turbos and possibly the over priced intercooler (very well designed, but still over priced) I don't think he is cutting corners. I tried to tell him not to go too big for the snails.

 

I just said that because others are saying that their are much better kits with quicker spool ups and better more effeciante power gains for a little more money.
I would hate to see him get into the same mess that he did before by saving a little of money and regretting it later. IE cutting corners.

 

The two are not mutually exclusive though I can see why Turbonetics' website might lead one to believe that - I just went and read their website and it made me think that too, but I've seen 60-1 hi-fi t3/t4s with my own two eyes (saw one on monday infact on my buddy's girlfriend's del sol) so I know you can purchase them. "Hi-fi" is just the name turbonetics gives to their T04E style compressor housing, as opposed to the T04S style housing. It's a little misleading because "hi-fi" might make one think it is better than standard, when it actually makes the turbo flow a little less than the 'normal' 60-1 with the T04S housing.

these websites sell them (just ones I found with a quick search)

contact these guys they do alot of the FI work on g35s and 350z's in the NY area

www.vinnytenracing.com

 

I'm pretty sure he lives halfway across the country unless he moved and didn't change his location under his screenname.

 

Yeah he lives in LA, so NY is not close to him at all. Atlanta or Houston would probably be the where he would go if he doesn't install it himself or locally.

 

for the money you have spent so far, why didnt you get like an APS or GReddy TT full package?

 

Sorry guys been out of town so i haven't been reading up on this thread.

First off imo the SFR kit is the mother of all kits when it comes to the Z. This kit cost almost 8,000 off the shelf so its not like it is a ebay turbo kit . Now i am not saying it is better just because of the price, but it offers more out of the box than some of the other kits. This kit, unlike Greddy or APS, use a tubular equal length manifold which is a big plus based on my knowledge.

Now i will admit i thought the turbo selection might be on the big side, but after talking to tim (designer of the kit) he talked me into getting them due to the fact that he has them on his Z (w/ stock block) and he said that the lag is not that bad. I also talked to a guy who had a g35 w/ a greddy kit who has rode in tim's car before and he claimed tims car pulled harder than his g35 which has a built motor and is making more power than tims car. The larger turbo can also serve as a form of engine protection also if you think about it. I will be able to make more power at less boost than say the greddy turbos thus reducing the thermal load on the engine.

Also the intercooler did seem over priced, but after searching for a identical match it isn't as overpriced as i thought. Trying to build a custom one will only save a couple hundred bucks and wouldn't be worth the headache.

 

I think you're buying into other people's hype way too much. Each kit has their pros and cons, but the tubular manifold thing, in THIS case, is nothing more than bling. They (if done right) flow more and help the thing spool faster. Unfortunately your turbo selection totally counteracts all of that and you're going to spool far slower than greddy or APS and ultimate flow is a non-issue because you're a) going to be on a stock block, and b) never going to be shooting for 1000whp anyways even on a built block - the turbos and manifolds on the greddy and APS kits offer enough flow to get you into the 700+ whp range - only above that will you see the SFR kit start to excel in ways the APS and Greddy kits fall short .

The thermal load thing is malarkey as well on a stock block - you need to start going above like 20psi to start getting those turbos out of their efficiency- again a boost level you will probably never ever get to so why's it matter if you have turbos that can flow 500hp each? at normal boost levels like 8-15psi, the smaller turbos on the greddy and APS are probably more efficient and you'd have less thermal issues with those than with SFRs turbo selection (not that either one is going to be a definitive advantage over the other in that respect.) You will never see any sort of discernable temperature difference at boost levels a stock motor can handle.

If you're happy with your purchase then that is really all that matters but you asked for opinions on your purchase. Area under the curve is what matters and in that respect, Greddy and APS both destroy the SFR kit. At the same boost levels on a stock block, an APS/Greddy setup will hammer an SFR setup. I just looked at dynos of the SFR kit and it looks very laggy, the dyno's on SFRs own website are not seeing 9psi of boost until like 5000rpm...

 

No don't get me wrong, i am open to opinions. As you stated thats why i started this thread.

I knew the kit wasn't exactly setup for midrange power, but i got it for a great price and hopefully i will be able to use its potential one day. I was just concerned w/ how laggy it might be for the time being(while on stock block)

 

Hey gabe, whats up!

Actually this kit (retail cost, but not what i paid) costs more money than the greddy and aps kit and is of better quality IMO.

 

*update*


The kit worked out great. Had to modify the frame rail a little in order to fit the big ol snails. Overall though i am pretty happy with the power curve. Not to bad for 7.5 psi

 

Congrats! Full boost at 4500rpm's.

How much HP do stock 350z's put down? (Trying to see the $$/HP ratio)
Did you still get it all done, including install for 6k?

 

on that dyno the revup puts down about 230whp.

No the installs and parts cost WAY more than $6,000. I ended up upgrading a lot of the parts i intially had. Figured might as well do it 100% right the first time.

 

nice numbers, spoolup was just like I predicted it'd be. glad you are happy with it.

Wizard, based on what I know about 350z turbo kits and install prices, I'd say he was more like in the $10k - $12k range for the parts, install, and tuning, perhaps even more (I have never specifically priced the SFR kit like I have the APS and Greddy kits).

 

. Guess I assumed you would install it yourself, then have it professionally tuned.

So much for your 6k parts budget stated in post #8. Happens to everyone. The classic "If I spend just a little bit more, I can get xxxxxxxxxx and be done with it" syndrome. Glad you're happy with the final results.

 

i don't know if he installed it himself, those figures were assuming he had Forged do all the work.


and come to think of it, I think he said he got a really good deal on that kit, so his actual price might well have been lower than what I estimated. but assuming that's a kit that costs 6k-8k with any extras, that's what I'd assume for a build of that nature done all at a shop.

 

yep my estimated figure went a little over. I ended up getting assigned to a project working out of town so i wouldn't have been able to have the time to install it till like Feb. I decided to just drop it off at sharif's and letting him do everything. I am glad i did since he ended up having to modify the **** out of everything to get it to fit right.

Here is what i ended up having installed:
SFR TT kit
CJM fuel return system
walboro fuel pump
RC 440cc injectors
Utec w/ map sensor and remote switch
Innovate Wideband 02 guage
HKS EVC 6 boost controller
Solid Motor mounts
Clutchmasters 6 puck clutch (sprung hub)
Stainless steel clutch line
Tein Monoflex coilovers.

Overall the car feels Totally different. I basically went in with a fairly stock Z and now the car feels like it is deffinetly track worthy

 

The sedan will be getting the JWT kit once I get my house. Great job Chris. I guess in another year you can drop in the built motor. Have any idea what you want? I am going for GTM Stage 1 block with GTM stage 1 heads and FCON managment system. Basically a $20K build but I only want to do this once.
