I finally have enough to start the wifey's Turbo project. I was just about to contact Hondadriven and order the Greddy, then I come across the groupbuy for the apex for $1299. Which is the better system,and why? This will be for 5-6 psi with proper tunning.

1299 is a good price for the apex kit, thats prolly the lowest i've seen, if your only gonna do 6psi max then i would go with the greddy kit on the d16, the td04 15g spools much faster and since ur not gonna go any more boost, you would be fine with a greddy kit... my .02

Sohc Driver

Sorry..they greddy 15g does not spool faster....the apexi kit is superior over the greddy kit because it is a ball bearing turbo rather a fluid bearing turbo. You have faster spool up and make more power. Since it is ball bearing, it gererates less friction on the shaft and also the shaft is also lighter for the apexi ball bearing turbo. Allow for a better spool. Also the Apexi kit price has dropped because, its really what its worth. This whole time this kit has been over priced because it was brand new. The price has finally dropped to where it should be. I say go with the Apexi kit.

I'm gonna have to stick up for the Greddy kit for obvious reasons....my signature. A buddy of mine has the drag gen 3 kit and its pretty shitty. I agree with Sohc Driver that a ball bearing turbo is better, but his doesn't really hit till a little after 5k, allowing 1800 rpms of good power on his y8 before he has to shift. I think the specs on his turbo might have gotten fucked up.

M.A.R.C.

mmm damnit i wish this price was there when i pieced my kit together... oh well... I my T3 60-trim

Thanks, what RPM does the Greddy reach full boost?

civicudesire

Trust me I have owned the greddy kit on my y8 and have also had a ride in y8 with the apexi kit and I would say APEXI all the way. The quality of the kit and the low price on them now should be enough for you to choose apexi. You wont regret it.

I have the apexi kit and Im at full boost by 3000rpm. If i take off my boost controller im at full boost by 3400, and at around 4 psi at 3000 , full boost is 7.5psi.

Sohc Driver

an aquaintance here in oklahoma reaches full boost at 2500 on his D16y8 with the Apexi kit. 3400 seems damn high almost where a t3/t4 hybrid would reach full boost at. The greddy kit on the d16 usually reaches full boost around 2800-3000

Is your car tuned to run that boost? It seems to me that the apexi kit with no intercooler or fuel management or anything would cause problems very quickly...

p0gi

the cars an automatic. So it wont spool as fast because between idle -3000 rpm the torque converter is a dog and slow as hell. after 3000 the car pulls wicked hard to redline. as far as tuning, im running an msd btm at about 1/2 degree per pound, 450 mitsus, vafc and tuned with a wideband 02. I think i could run more boost. Ive seen boost go as high as 10 pounds coz of the boost controller.

Ok the type of turbo the Apex *Hatch Black Edit*.*I Will Purchase a Hondata* I just want to make sure this is Apex kits is something I regret. If it truly spools as quick as the Greddy I am all over it. The only other disappointment is no one has information on how to mod this Turbo for a 96 and up Civic. Which means I am going to be working blind hear with this kit, unless someone here has completed this installation before.

sorry my bad, i coulda sworn the greddy was ball bearing as well, my mistake anyways after i posted, i did some search on the apexi kit, seems like a good kit like everyone says...AND you can't beat that price...i should have waited

dabrown

Polo, How about the install for later year D16's. Will I need to modify any of the piping?

Daniel

what are you talking about? any type of forced induction needs fuel management. good luck with the stuck fuel sytem doing the job for you. You'll at least need some type of missing link/FMU setup or a piggyback computer to hook into the ecu.

and the kit should install the same as the GReddy, meaning everything will bolt up fine and shouldn't have clearance issues. the only thing i can see modifying might be the charge piping, but that's minor for the price you pay for Apexi's kickass kit on GBC.

Guys, does anyone know what PSI the apexi turbo starts to become innefficent? I was planning on going T3/T04e...but after seening the price on this kit,,,i'm tempted to buy it right now....

My goals are 250-300whp
I have hondata, and my engine will be built in a week or so.
CP pistons
Eagle rods
ARP headstuds
Cylinders will be stabilized
etc..

Will the apexi suit my needs for close to 300 hp? Also, i dont give a damn about spool up,,as long as it hits full boost by 4000rpms. Some of you have to realize, quick spool up is awesome, if you have the tires to keep the grip....
Thanks

I don't know the full specs on the Apex turbo but I would consider it a small-medium sized turbo, where a T3/4E is rather large so they're not really comparable.

FYI on my SOHC I got full boost (9 psi) by 400 RPMs with a T3/4B.

Same turbo on my B18B is spooling mad fast, y0!

I believe from what I've seen the Apex kit requires little or no modification to fit newer Civics.

And uh, yeah. Post your results from running a turbo kit with no fuel management since 5 PSI or less requies none

ill_take_one

Ok thanks for the info. are you referring to me in the quote? If so, i'll be running hondata s200b, 550cc injectors, walbro pump for fuel...

Anyone else?

edit: never mind hatchblack, i am a dumbass edit:
peace

I wasn't talking to you, unless your screenname is really dabrown and you said "Ok the type of turbo the Apex has does not really need to have a Fuel Manage Unit if you are only using 4-5 psi".

It was a joke either way, ah and damn you edited quick

for custom turbo setups and solid engine management!

boostsohfast

Like I said before I think my buddy got ripped when he ordered his kit. If I am correct, can't you get any trim you want when you order the apexi kit? I know my friend didn't specify when he ordered his.

Daniel

i believe it only comes with one turbo ... the IHI ball-bearing turbo and that's it. the only other options are the GT-spec intercooler and A'PEXi fuel management stuff.

dabrown

Alrighty Hatch Black!! LOL There is no way I would run any turbo without an FMU. If you noticed I put Hondata afterwards to make sure you guys understand I will use some type of FMU. I will edit that of course. But seriously I think I am going to get the Apexi I just feel bad because I have received so much help from Hondadriven I would prefer to purchase the kit from him. I am waiting for a response to see if he can get the kit for the same price.

well here is my thoughs on the two kits.

*if they were about the same price.... hands down APEXI kit over greddy
Both of them are top notch quality and figment issuse are perfectly. the greddy 15G turbo is great for low boost and street applications. The should reach full spool on a STOCK D16 before 2900rpms. Over and over people have made good power amount with this kit on a D16. They are great for the price. The turbo does loose power in the highend. For example some people have used the D16 greddy kit on B16 and LS/B20 motors it. it will spool up quick..realy quick(1800-2000rpms) But the downfall is that above 5,800rpms the power really dropes/dies off.

The APEXI kit is same as above ^^^^ but the manifold is stronger, turbo is better and quality with overall kit is slightly better! but to a turbo newbie you won't be able to tell the difference. the Apexi has a IHI p13 ball bearing turbo that is very efficiant and with the charateristic having great low end boost response as well as high end. The turbo will not die off even on B16 and other bseries motors. the turbo is the best part of the kit. however the turbo cannot be matted to other manifold (like the greddy 15G can bolt on to the HKS manifold) making a custom plate for the IHI turbo is really hard. The apexi kit should reach full spool on a STOCK D16 at about 2,650ish. Both spool up about the same but the Apexi is noticably faster. The apexi turbo can take about up to 16psi before it really runs out of steem & becomes less efficant.

*with a D16 a t3t4 will reach full spool at 4,500rpms not 3,500 it normanlly will take a STOCKB18b/B20 to reach full spool on a t3t4 at about 3500!

*The apexi kit is able to push out 300whp but it would really be maxing out the turbo. If you really want to get 300whp get a turbo so that you'll have room for upgrade. If your goal is 250whp + plus maybe little more when you get the common "Boost Bug" (when you want more and more boost;hensce the term boostaholic) You can easly do 300whp with a BUILT D16! BUT when it's fully built you might was well get a larger turbo and push 20psi. for your case i would get a T3 or T28 not the GT28. the T28 is larger than both GT28 & the apexi turbo and will do 300whp with less boost and still reach full spool by 4,000rpms.

Another great turbo for the D16 is a GT28... which is about the same compared to a IHI p13 turbo, just that it's a ballbearing Garett and has a T25 turbo flange than is MUCH easyer to find a manifold for.

* fellow honda-tech member made about 250whp and 240tq on a bone stock B18a and the apexi kit at 10psi with FMU and sms. he just got hondata and should be running wayyyy better numbers.

i got the 92-95 greddy kit, didn't need to modify any of hte piping...also got the fmic type 24 i believe... had to make a few mounts but it was no big deal, EASY install
