I just purchse a 95 Honda Civic hb si. The car currently have a 98 ITR swap with a 00 ITR tranny (w/ lsd of course). AEM short ram intake is the only mod that had been done to the car. Everything else is bone stock with stock gsr exhaust manifold and stock si exhaust.

Here's the thing, i been searching all over h-t forums for good set-up for itr motor and did't come up with nothing. I even tried googling it...nothing. I tried a b18c1 (gsr) search and found plenty of set-up for that motor. Im just kind of fed up getting flamed by asking nooBi question like "what kind of header should i get" or "would this skunk2 IM make my car faster", stuff like that. I mean i did my research and stuff and know plenty about my motor (b18c5). But i guess not enough.
So, can someone with experience or who have delt with this motor tell me what should i do to the motor as far as performance goes. Did't really set a goal yet but if anything im shooting for mid to low 13's. Don't really have a budget since im not planning to do all this at once. Just when ever i have extra cash.
So, this is where it gets hard for me since imstill a nooBi and this is the first motor that im going to "build" i guess. I did many research on the ITR motor and notice that alot of stuff that we normally would replace on other motors like the b16 and the b18c1, the itr already have it upgraded. Like intake manifold, i went off and ordered a skunk2 IM. Later on, i figured that the Skunk2 IM is very similar to the ITR IM. That is was really only an upgrade for the B16A. It is listed for the B18C5 because it shares the same head casting with the B16A (PR3).
...waste of money.
Then i went off to buy new clutch and flywheel for the car and later found out that the ITR clutch and flywheel are already upgraded the way it is and it was just pointless for me purchasing those stuff.

So heres where i need the help. What can i do to my car to make it faster w/o buying pointless parts thats not needed for the itr motor. here was what i had in mind with all the research i did

-hytech replica header
-test pipe
-catback exhaust
-tuned the motor

currenty have a chipped obd1 gsr ecu in it
vtec engage at 5700 and redlines at 8600. What ecu can i buy to make the vtec kick in sooner or should i just get a vtec controller
thats the only thing i can think of with as much research i did. im sure there is more i can do i just need to know what.
i hope someone can take me seriously and help me out.

thanks in advance h-t, anything would help.

Flamer would be ignored, im here because i need help and not afraid to admit so.

 

bump.

no help...anyone?

 

ok lol. thats alot.

i have a 98 spec swap in my 00 hatch. the mods im using are as follows.

head was ported and polished by alaniz
buddy club springs
buddy club retainers
new oem valves
new oem seals
head was milled a lil(i dont remember how much)
buddy club spec 4 cams
4.9 final drive in the tranny
comp clutch stage 3 clutch
hasport stage 2 axles
skunk2 fuel rail
310cc injectors
toda header
stock intake manifold just port matched
maxbore 68mm throttle body tapered to 65mm
p28 ecu with hondata s300
theres more but i cant remember right now

the car made 208whp and 156lbft

i love this motor. it doesnt wanna stop going lol. when tuning i stopped making power at 9600rpm so i shift at about 9800rpm.

all on a stock bottom end with arp rod bolts.

 

how much was it running 1/4?

 

i havent gotten a chance to go to the track yet. it should atleast pull a 13. its a cx hatch with nothing behind the front seats lol. i think with a set of slicks it could be in the 12's

 

damn. that must mean my chance of hitting mid/low 13's are pretty slim then.
considering im going for a daily driver with complete interior and ac, ps and cruise control.
not to mention that its a si too.

 

I have a 96 jdm b18c5 in a 91 si street car with full interior and I don't have
a lsd yet my best time on motor 1s 14.5 at 95 mph, on a 75shot dry zex kit
I went 13.6 at 101mph. You might break into the 13s as is with a good launch.

 

My build
97 b18c
stock head
skunk2 springs and retainers
skunk2 stage 2 cams
310cc injectors
aem fuel rail
2 layer headgasket
68mm throttle body
intake manifold port matched
JDM 4-1 header
not yet tuned but tuned with chrome when ready.
Im hoping for at least 190hp at the wheels

cause u have no lsd in your tranny and you dont have a 4.7x final drive either. if u had the 98 spec tranny you would be a lil quicker. what elevation are you at? because with a 75 shot dry u should be in the low 13's maybe even high 12's with slicks. something isnt right with your setup.

14.5 just on the motor isnt good (no offence). i was pulling 15.1's consistently and a all time best was a 14.9 with my d15b7 motor.

my built gsr motor first time out with my babying it pulled a 13.1 at 108mph and the block is still a 1.8L

 

I don't think I want the 4.7 I drove the motor with that tranny and just cruising on the freeway at 70 the revs are at like 5000+ i'm getting a gsr tranny with 4.40
like I have just with a lsd and the 14.5 was with cheap street tires and my car
with me in it is 2500lbs. What car did you do 14.9 with a stock d15 my ls swap
ran 15.1 and the stock d16 that came with my car ran 16.5. So I call
on a stock d15 even pulling in the 16s.

 

any more set-up guys???

 

Common ITR engine upgrades are as follows:

Header upgrade
Camshaft & valvetrain upgrade (can range from stage 1 to a wilder stage 3 cam)
fuel injectors & pressure regulator upgrade
Final drive upgrade for better acceleration off the line/out of corners
headwork if you really want to get down n dirtay
bigger throttlebody w/match ported intake manifold
air intake system such as an AEM CAI
ECU upgrade and dyno tuning time to dial everything in

any or all of these options will bring you more HP.

As for your ecu tuning, 5700rpm is actually the stock type-R vtec crossover point

as some added info that you may or may not know about the B18C Type-R engine:

A B18C-R is a basically a GSR block with a B16A head, both of which have been upgraded with a special set of camshafts, valvetrain, hi compression pistons w/special coating to battle off vibration, heavier crank to battle off high rpm vibrations as well, and slightly lightened rods (comparable to GSR rods). Also a bigger bore throttlebody and upgraded intake manifold, not to mention the LSD equipped tranny.

A lot of people are content with a stock Type-R engine and mild upgrades such as intake, header, exhaust, while others strive for more power by either forced induction or NA upgrades.

 

thanks man. those were some great info.
vtec crossing over at 5700 is really late though...for me lol.

so the only thing that can make it cross over sooner is vtec controller correct.
i want it to kick around 5000-5200.

d15b7 in a 94 hatch gutted.
ex tranny
50 shot wet.

but something tells me it was larger than a 50 shot because the motor hesitated like a **** at first and then took of like a midget on steroids. i only got about 8 passes with that motor and a 14.9 was the best i got with it. for a 14.9 i launched it at 5200ish and managed to get a 1.9 60ft. it was on slicks btw.

instead of just setting your vtec lower you should tune it. if u set the crossover too low you can lose power. honda put it there for a reason and if your going to keep the internals the same that i wouldnt change it. the only thing that could benefit from changing your crossover point around is if you get a set of aftermarket cams. certain cams make more power with the vtec crossover at different points than the stock 5700. my built gsr's crossover is very high(6600rpms) but thats where it performed best. (im running skunk2 pro3's)

 

what cams would you recommned

i recomend either skunk2, buddy club, or rocket motorsports.

if you go with skunk2's i would reccomend the pro1's or pro2's

if you go with buddy club i would reccomend spec 4's

if you go with rocket motorsports i reccomend the m22x's

your going to need springs and retainers for all of the above cams.

i reccomend ferrea springs and locking retainers. also make sure you clay the motor just to be safe so that u know your piston to valve clearances are the same. also if you do it yourself make sure u degree the cams and set the valve lash accordingly.

 

so im guessing that you are talking about the cam gear and cam shaft correct?

 

for cam gears i reccomend skunk2's cam gears but certain companies reccomend there own stuff.

but i was talking about cams not cam gears.
