** Apexi B-Series Turbo Kit Review **

[integlspwr2k]

Motor: Car: 1992 Honda Civic Hatch Back Si First Gen B16 W/ GSR Trans & GSR Distributor Stock Block & Stock Head. Nothing internally changed. Turbo Kit: Apexi B-Series Turbo Kit IHI P13 ball bearing turbo compareable to a t28 .86 a/r yes that does have a jdm t25 turbo flange but the nut/bolt is aranged slightly different. Apexi Silvia Intercooler Apexi BOV Fuel: DSM 450CC Inecjtors W/ Resistor Box Walbro 255LPH Fuel Pump Ignition: MSD 6A W/ Blaster SS Coil ECU: Uberdata ::Tuned By Gary Miyasato:: Basically this kit is very RARE from what I know. The kit was originally for a Integra Type R but piping was cut & welded for a 1992 Civic Hatch Back With B16 Engine. Cars Best Quatermile time was: 13.7@104 10LBS of Boost (Running AFC HACK, Before car was tuned with UberData) Will post pictures of the car later on today. If you have any questions about the turbo kit, Charlie Moua or I can help you answer it. -integlspwr- Here are the pictures that everyone requested.... Modified by integlspwr2k at 4:49 PM 12/26/2003

Very impressive.... I wanna know how to contact the person who tuned it using Uberdata... I'm about use Uberdata in a few days...

how much boost?

10lbs of boost.

Great job Edgar!
I'm jelouse of that rare apexi kit for Bseries...... LOL

Unfortuneanly this dyno graph does not how the torque cruve of the street beast but one can only imagen how nice and flat it would look.
I belive this setup made 250whp and 175tq @ 10psi

I have always been a fan of streetable setups for turbocharged cars. I mean i love seeing dyno charts of 400+whp setups and seeing the crazy linear pull of power from 5,500rpm to 9,000rpms from a sc61 but for my needs and daily driving fun I think small turbos onwes. Everyone is going with t3t4 and the new turbo fashion is Precisions turbos. Every other dyno chart of t3t4 and hondas are so commonly done. I really love seeing other people use other turbos that give different results.

From the looks of it I think you should be able to boost up to 12psi on 91 octane if the weather drops a little. Your netting 250whp so 280whp at 12psi would not be unreasonable at all. Hell 250whp is crazy for a damn street car, most people ride around in d16(120whp) b16 (150whp) b18c1 (165whp) and think their car is fast enought......... just to put into perspective. Even if you had a DRAG III KIT tuned hondata I highly doubt you would of gotten better number, if anything same peak power with more like 160tq.

I'm glad to see some good numbers from this kit. Back in the days people were some what ragging on Apexi kit cause of the price compared to Greddy sohc kits but what they did not understand is the quality material of the manifold and the kick ass IHI turbo! This turbo kit I think is hands down the best street setup made open on the market. The power delivery that it produces are very nice yet not crazy. The pull and powerband it gives out is very much like the smoothness of a NA motor or a ideal small turbo givin from the factor for that motor. I'm not saying its better than garrett, precision, turbonetics ect... just saying it's what I have found best for street use on a broad veriety of honda motors..... all this is IMHO

glagola1 made:
238whp and 226tq on stock LS 10psi
268whp and 247tq on stock LS 14psi
integlspwr2k made:
250whp and 175tq on stock b16a2 at 10psi

I hope to be the 1st honda-tech member to have it on a stock GSR. I'm thinking about concervative numbers such as:
235whp & 175tq @ 7psi
280whp & 205tq @ 10psi
300whp & 230tq @ 14psi



Thanks Edgar for the Apexi dyno chart. I have long waited to see it on a dohc vtec motor since I saw glagola1's LS dyno chart!

just so we all no.
when did you start & reach full spool @ 10psi ?

what is your vtec cross over set at...... power is so damn smooth, it's hard to tell

when did you get PEAK torque?

[norcalcrx]

Decent #'s for Uberdata. You underestimate the Greddy kit though. It can make power when done right. Belive me i know. Congrats it looks fun to drive.

[integlspwr2k]

I edited the dyno graph to show torque also...

So it now shows both HP and Torque..

The car was tuned again for 6 hours straight but unfortuatnly the car was in a roll over accident a few hours later at a open track event.

From what my friend (the guy doing the driving) with my tuner, the pull was even stronger on the top end, and the turbo spooled a 1000RPM's earlier.

Btw the engine was a B16A, the first generation B16's.

haha i saw your thread.. You my friend is and exception!
Also for a stock d16 yeah the 15g is plently!
If you had and Apexi kit on your setup and retuned I can promise you would make more hp & tq.

but take for example a
STOCK B16a1
greddy 15G kit
FMIC
obd-0 PR3
tuned by hondata by a really good tuner
The owner of this car is a honda-tech member too...
****** @ 10psi he only made 209whp and 165tq with power flating out and slightly droping off at 7500 to 8200rpms. I've been talking with him and I belive he's switching over to a t28 .86a/r which will make it near identical to this dynochart BUT it should make more topend over the P13 IHI apexi turbo.

[Jkan2001]

Wow those are kind of weird torque numbers for that whp. I had the apexi kit with the RHB5 for my sohc and i made 176/173 wtq on 8 psi with the hack. I'd think with a quick spolling bb turbo you'd make almost equal wtq and whp. Good numbers though and nice trap, and yes the apexi bb kit's produce REALLY quick spoolup. Notice the peak whp is before 5000 rpms which i thought was a bit odd (this is how i was able to beat evo8s, s2000s, and a 94 nsx with an instant torque jump from the beginning of the race) It also netted me a 8.5 in the 1/8 mile

haha your tq is the nearly the same as the b16.... funny and true. This is why many people dislike the b16.... torqueless monstor.
Finding a turbo that will allow fast spool with out restricting the topend is very hard to do...... but i'm sure you'll agree that the P13 compliments the motor's TOPEND ablitity to breath as well as working nicely with the little displacement of 1.6


BTW that's a nice ass d16 street/mild setup bro!

[SiRkid]

d16's ahve longer strokes..more torque

that thing seems to be hitting full boost awefully late imo.

where did you get the kit from?

can we get some pics of how it looks

[martinscott]

What makes this car interesting, the kit was first purchased by my friend w/a ITR. At 12psi, the car only made 220whp w/ a afc and fmu. Integlspwr2k car was originally tuned on the street via integlspwr2k's ass dyno. The dyno plot you see are the results of the street tuning. I drove the car and did not like the response in the low and mid range eventhough the top was killer, me and the tuner spent 9 hours tuning on the street. If you like the old dyno #'s for a p.o.s. kit, you should have felt the car after we were done with it. 7psi @ 3000, full boost @ 4500. Put it this way, we loaded third gear and when it hit 6200rpm, the tires began to burn out!! not bad for a 1st gen b16!!

Can you keep A/C with this kit??

Yes you can keep AC and powersteering with this turbo kit.

I wanna see pics. Im so anxious. Plllleeeaaaseeee

what model number is the turbo

yep, the injectors and resistor box made those numbers. The numbers are suppose to be higher like martin scott mentioned in a previous post.

He was thinking 260 or so.

From the looks of it I think you should be able to boost up to 12psi on 91 octane if the weather drops a little. Your netting 250whp so 280whp at 12psi would not be unreasonable at all.

Even if you had a DRAG III KIT tuned hondata I highly doubt you would of gotten better number, if anything same peak power with more like 160tq.

This is a sweet set up. I haven't seen an apex b series kit anywhere. But you can definitely get the same #'s from a drag kit. I was making 247 whp, 173 tq with stock injectors with an safc @8-9 psi.

[martinscott]

tslag- you're right...I bet the car could make close to 280whp on pump. but 250whp on the street is not enough. I've seen a stock gsr on pump make 330whp@10psi. now that is a fun car!!
