anyone with b18c5 in their g2 teg ? how do you like it and how much did you spent ? on top of the motor swap, what other items do I need to change as well ?
Joe
Dan (g2guru) has a b18c5 head.
its usually much more cost effective to make your own b18c5 “look-a-like” engine… commonly referred to as a “poorman’s ITR”
you use:
-b18c1 block
- itr pistons (if you use the jdm ones, you’re on your way to something better than a b18c5)
-pr3 head (any b16a, b17a, or itr head will work, but itr head’s are usually hard to find… so you might as well just use a b16a head and send it to portflow which will make it even better than the itr)
optional, but nice to have to help you make it even closer to an ITR engine:
-itr cams (or get some ctr’s which again will make it better. Or you could even get some toda’s or jun’s for even more power!)
-itr intake manifold
-itr tb
typically b18c5 engines are very expensive, and very hard to find. you can build your own poorman’s itr like i listed above and have something slightly slower than the b18c5 (which can be made faster as you mod it), or much faster than the b18c5 (thats if you add the better cams, headwork…j)
well if u really want a real b18c5 i say try piecing it together u know look for deals on the partstrader or ebay stuff like that!
atleast i know thats would i would do if i wanted a b18c5! hth:D
91integs, would this poorman’s itr pass calif’s smog test ?
no, the poorman’s itr would not pass smog. (well, technically it would pass emissions, but the ref won’t give you a bar sticker for it)
And i’m not even sure the smog ref will pass you if you just swap in a stock b18c5. There are MANY technicallities they can get you on. Here are some of them:
-not the itr tranny, you fail
-not all the exact correct smog equipt and sensors, you fail
-not the itr ecu (obd2) you fail
-not using obd2, you fail
-the smog ref i talked to even told me there was a good chance that if i put a b18c1 into my car i’d need to swap the fuel tank as well!!!
now, like i said, those are technicalities, if they want to be nice then they will pass you, cause that stuff really doesn’t matter. But if they are picky, don’t like you, or don’t like something about your swap they won’t hesitate to fail you… and they will have the rules behind them when they do so.
This whole smog ref thing here in cali sucks! I’ve considered a few engine swaps for my car, and after considering my options i’ve decided a b17a is the only engine that i actually have a chance of getting a BAR sticker on, all my other options (ls/vtec and poorman’s itr) would definitley not pass. And b18c1 just isn’t an engine that i wanted, plus it’d be a lot harder to pass than the b17a, especially the way i would have wanted to build it.
move to the Northwest. you will pass. no visual 
So what would you guys recommand for a Kalifornia resident who wants to fix up their G2 LS for more hoursepower and restore some reliability (daily driving) and I want to have a good idel too. Do I just stick with bolt-ons ?
Joe
for the poorman’s itr, do you need to change axles, etc. also???

Joe [/B]
I paid $1700 for a 96 ITR b18c longblock with intake manifold.
I used the distibutor, injectors,tb,ecu, tranny etc from the engine that I took out of my car.
joe wu: there are the options I’d suggest:
if you have a 90-91:
- Rebuild your stock engine, throw some cams in it… these engines have potential, just not as much as a vtec engine
if you have a 92-93:
-
Rebuild the stock engine.
-
Throw in a b17a. This engine will bolt right in, and is VERY easy to make smog legal.
Now, there are two more options that i didn’t list:
-
Say, screw it! and just start getting smogged illegally. Its really not a big deal, lots of people do it. and in this case you can put whatever the hell you want in your teg.
-
If you have a 90-91 you can try a b17a swap (this is what i’m doing). This swap isn’t very cost effective, because of all the wiring that needs to be done. In order to pass smog you HAVE to run obd1… which means a whole lot of converting. I’m still unsure of how much work its gonna be, but hopefully i should find out this summer. Also, this route is much more expensive than if you were to throw the b17a in and stay non obd.
92GS-R: I’m pretty sure the only difference in axles between all the b series engines is length…and thats due to differences in the car, not the tranny or engine. So, i’m pretty sure you can just use your stock axles.
i have a b18c in my car and it wont pass the visual smog test,now what 91 teggs said was right they could very picky , but if you got all the smog divices hooked up a obd1 gsr motor 94-95 the motor must be usa not jdm you have the right ref and every thing good it is possible to pass a b18c but 91 teggs is right it is easier to pass a b17a
Are you saying if it is a usdm b18c1 or b18c5 then the smog will pass ? it is only if you are using JDM motor that you will not pass ?
Joe
if you put in a jdm engine you will NOT pass smog, i guarantee.
if you put in a usdm b18c1 or b18c5 then you ‘might’ pass smog. It all depends on how clean of a swap you do, and how nice the ref is. Cause to pull it off and not spend a fortune on it you’ll need a really friendly ref (slightly less friendly if you have a 92-93).
Hi guys,
I’m new around here and I couldn’t resist hopping into this thread. I also live in California, and I have a USDM B18C1 w/S1 tranny sitting at home which I intended on dropping into my 93 LS. I also planned on having the car Ref’d in the near future. Now, I was told that I “might” run into problems if the Ref notices that I’m not using the Hydro tranny intended for this motor (S80). Is this true? I did a search on this, but I just wanted to know if anybody got to talk to an actual smog ref about this. Also, what’s this I hear about swapping out gas tanks? Geez, is this true?
Thanks guys,
Zero
zero: since you already have an obd1 car it won’t be as hard… cause you wont have to deal with wiring. Your main problems will be the tranny and all the misc smaller accessories.
its all going to depend on the ref you get. Some of them won’t even check the tranny. But some of them are sticklers and will check every little detail.
the smog ref i talked to told me that there was some smog thing or something on the fuel tank of the b18c1 tegs, and that since that was there i would need to swap over the tank. I’m not sure if this is true, or if they would even check (i doubt they would).
Just make sure if you attempt to do the swap that you do it by the book! swap over ALL the smog equiptment, and all the 94-95 sensors (make sure you use 94-95 b18c1 parts!! if the b18c1 is a 96+ engine it will make your life a whole lot harder… if your engine is a 96+ one then i suggest swapping over all the different parts with 94-95 parts… you can easily fool the ref this way and just tell them its a 94-95 engine so you can run obd1). I would go in there with your car as stock as possible, make sure all the bolt ons you have are legal and have the carb stickers or the EO numbers.
I was originally planning on a poorman’s itr setup and that would definitely not pass. and in my situation a b17a just works better than a b18c1 for a handful of reasons… one of them being that it should hopefully be easier to pass smog.

Hey buddy, pal, how about hooking me up with those goodies? Good combo!
91IntegGS: Thanks man, I appreciate the info. Sheesh, all this trouble just because of those stupid CARB regulations 
Oh well, in the end I know it’ll be worth it…good luck on your setup!
whiteyg2RS: Hehehehehe…
