any thoughts or suggestions? tips, tricks? what will work, what won't?

 

pretty straight forward.
reuse Si harness
change the iat plug to fit the iat on the integra motor
mighthave to extend the wire a bit.
otherwise everything else should swap right over

 

how about resleeve Si motor to 84.5mm and (maybe) a lightened/balanced
gsr crank?
would that be a good idea for an Si...
i would imagine it saves you the trouble of the swap and buying a whole other
engine...

 

i'm getting the motor for a good price. want to be rid of the b16. nothing but bad luck with it. ya know? what about the b16 tranny and axles? will those also be a direct fit? i was planning on using them if i can, being that the b18 i have doesn't have with the tranny. only the block and head. thanks for the help guys

yes tranny,clutch and mounts can be reused.

 

your gonna need an new header, maybe a skunk2 intake manifold as well. keep the tranny and save up for lsd.

 

yeah, you will needa b18 header
skunk2 manifold is the same as itr so noneed for that.

 

So an USDM ITR ECU will plug directly into the 99 Si wire harness with no modifications?

Even though the 99-00 Civic's changed ECU plug styles, I thought the Integra's did not follow suit here.

 

You can use the Si ecu HOWEVER a VAFC is highly reccomended.

I was running super lean when I first rolled into the dyno...another draw back to the Si ecu is the fuel cut at 8000 rpm...the ecu alone should be worth a couple tenths at the strip.

I have a usdm P73 I am going to drop in next week and I am looking forward to the B18 maps vs the B16 maps...that and finally being able to rev to 8600

I would get rid of the B16 tranny though....a newer S80 tranny should go for 1200 or so and while the gearing may be similar the synchros in the B18 trannies are better and the diff is stronger as well. With a C5 motor and hard launches/shifts I would reccomend a tranny just for long term reliability sake...a JDM ITR tranny would be really nice for the FD.

These are just a few things but as mentioned before header JDM style 4-1 whether DC or OEM Honda its a big difference over stock. VAFC, FPR, fuel pressure gauge for tuning and a P73 with harness adaptor for your car (99-00 plugs ARE different) and I beleive you have to run an additional wire from the dist to the ecu (maybe its just for my DX but just a heads up)

WIth light mods that motor should be alot of fun and very reliable. Good luck

 

Last i checked, the 99-00 SI trans and B18C trans used most of the same parts.
there is nothing that makes a b18c trans any stronger than the b16a.

you can use a 00-01 ITR ECU but you have to have the immobilizer disabled.
otherwise it plugs in.

 

I was under the impression the B18 trannies have dual synchros vs the B16's which have single synchros? As well as a smaller/weaker diff? And a tendancy to burn up third gear....interesting

 

All b-series trans use double synchro first gear and single synchro for the rest
im not sure on the diff being the exact same, but its not any weaker imo.
The casing is the same part. tendency to burn up 3rd? probably coincidence

 

how much money would you spend for the *oh my God its a Type R motor* ? I wish I had a dollar for every ITR and GSR person I put to sleep with a B16a motor modified ... *sigh*

that money you spend to get an ITR motor you can spend on your current setup and have it running alot faster than the stock ITR motor, just a thought, I proved this many times at the street races ... made quite a bit of $$$ off the ITR and GSR guys too who upgraded to the almigthy type R motor.

the tapered roller (carrier) bearings ar the only difference, they offer a lil less resistance than the square type, but steve would you put a $1200 premium on that and an LSD ? I wouldn;t ...

greg

 

by 00 they changed ALL b trans to ball bearing instead of tapered roller bearing.

 

hmmm, interesting ... not sure why the 01 ITR tranny I upgraded for a customer couple weeks back had tapered bearings. It was factory sealed too *scratch* (bald) head

greg

 

I'm not going for the fastest street car on the planet here. i just want something with a little more than my b16 is giving me right now. i have an 11 second eclipse, so no matter what, the civic will always be slow to me. plus its my daily driver, so i need to have the least amount of down time as possible. but i thank all you guys for your help.

oh yeah, who said i'm leaving this motor stock????

 

wierd man.
but the dealers around here tell me they totally discontinued the tapered bearings.

 

Any idea why people say the B16 third gear goes out so much? I have been told by few people that B16 trannies are weaker (the diffs especially) ....I just wanna clarify that issue.

 

why not sell your civic si, buy a cheaper crappier civic, keep the money you saved and put it into making the ITR even faster

 

steve, I heard the same and when you mentioned it I was even more confused. We can get the tapered ones here, they are around $50 a pop vs. $25 for the square ones. So I just convert them all for people ... I think you're right but I got confused when I opened some guy's 01 ITR tranny and saw that.

sergek, its a myth and its no different.

as for the diff, any open diff breaks the same, I've seen many GSR and B16a open diffs break.

3rd gear breaks on any of the boxes because thats where everyone abuses it most, quickshifting and fastshifting from 2nd to 3rd. the syncro takes a beating ... the only other gears that are similar is 4th to 5th shift but who fast shifts those gears ? alot less ppl than the 2-3 shifts cause we're talking about 90-95mph vs. 105-115mph dependng on your redline and ratio.

IAT plug? can someone explain to me the IAT plug...

i'm doing this exact same swap in my car... and not because i'm looking for more power... i just happen to have this motor sitting around

 

... heh, yet another incident of Honda's unorthodox ways.

 

Thanks CHEETAH.....any reason why ITR trannies go for so much (probably JDM premium?) lol
