fairly simple setup we were at the dyno for an hour we could have smoothened it out , but this is what we have for now. I think it had more in it too, but time for some track time! This is in a 1991 civic dx four door.

stock jdm sohc zc (very similar to d16a6 88-91 si engine)
Mfactory catch can
dsm 450cc injectors
tuner toys 14b feed and return oil line kit
full stainless log manifold
3" downpipe off the turbo sectioned wastegate (reduced turbulence)
K-teller full 3" straight through exhaust with high flow cat
dsm 14b turbo (oil and water cooled)
6061 2.5"aluminum charge piping
4 ply couplers with t-bolt clamps
Turboxs Vport blow off valve
22x9x3 front mount intercooler
jdm zc lsd transmission
Custom euro drive kevalr clutch (sprung full disc capable of over 400 ft.lbs)
poly urthane bushings all around
PIC fully adjustable coilovers 10k and 8k?
autometer sport comp 2 boost/vacuum gauge (30/30)
91 civic si manual cluster
Converted to 5 speed
converted to obd1 (p28 ecu,obd1 non-vtec distributor, obd0 to obd1 conversion harness)
obd1 to obd0 distributor jumper harness (made from spare harnesses)
Walbro 255 lph pump
slim fan on single core 92-95 rad
battery relocation


Maintence:
valve lash adjustment
ngk v-power heat range 7's
throttle body service
decarbonized engine
cleaned iacv
re set idle adjustments
rewired fuel pump
compression tested & leak down

How much boost are you running?

quicksilver1689

prolly a good amount considering its a 14b turbo, nice budget build setup

sorry i didn't make that clear 11.8 psi and i think i could lower it some and make the same power because i think the timing was still conservative.

thanks, yeah it shaped up to be pretty good my goal was to hit 200 ft.lbs , but we got 198 ft.lbs on the baseline pull after just a street tune. He was driving it for 8 months before we were able to get it on the dyno.

LOVE THE SIMPLE SETUP! godd power looks like a fun powerband. pics of the car????

thanks, yeah i should get pics of the car up of the car soon

why only rev to 6.4K ?

looked like a killer graph until i looked down at the rpm.

It doesn't have a vtec head, however you could probably rev it out to about 7K if it is making power. I rev mine out to 6800.

It's nice to see another sohc zc making some power.

zex_cool

i rev'd my y7 to 7-7.2K back in the day. stock is 6.6K i think.
if its like a a6 head, it should have some sturdy springs. 7k aint ****.

i dont see it making more power but it would make for even a broader powerband. either way

Drew Peacock

THe sohc zc's don't really like high rpm in my experience get pretty noisy after 6krpm.

Nice result and the lsd l3 gboxs are rare.

well the small 14b seems to plateau at about 4500-5000 rpm and the torque seems to be falling off up top. To make the car more relaible we want to keep the revs down but still retain good power band so shifting he won't fall out of it. If he shifts at 6500 rpm he would have to fall below 4250 roughly. I am pretty happy for the tuning portion only being street tuned and then dynoed for an hour. The base pull was 213 hp @ 198 ft. lbs in gernally the same power trend. The goal to begin with was 200 ft.lbs and i was not really concerned for the hp.

yeah we were lucky enough to get that trans from a dohc zc swap the was in the car before. It really is an awsome transmission in my opinion and thumbs up that its lsd.

willyboyK20

good setup.
Any plans on ignition upgrades?

Also are you guys running a 3bar map?

zex_cool

ignition upgrades ??

stock dizzy is good for 500+whp

yeah we are running a 3 bar because it was given to me for free. No plans for ignition upgrades.

ARC 55 let me know if you find a good cam for the sohc zc. I am on the look out for one.

KingOfQB

You Can rev Higher y7 uses vtec valves springs and retainers

d16 has its own better than the other non vtecs besides y7 but 7k on stock will be fine

HiProfile

I'm curious why the torque plateaus between 3.3k and 3.8k, too much/too little timing in the lower boost columns? I always try to tune with as little boost as possible, then max, then places in between if I have time.

Aside from that, looks like a good deal of power from a 14b and a stock non-vtec motor.

quicksilver1689

yeah it does have a very nice powerband, im diggin the torque. didnt notice it was a non-vtec motor, bet that helps contribute to the torque. never understood why but the non-vtec motors typically have high tq numbers on par with hp.

hondaLovin

good numbers for a little baby turbo.

lmao you must of had a bad sohc zc or something. i have a sohc zc and it loves to hit 7200 rpm. and its not noisy

OP: anyway great numbers and simple set-up i love it. glad its non vtec man people swear that the sohc vtec's are the only ones that can make good power. glad your being different.
