I am getting ready to start building my motor and wanted to see what kind of advice you guys have. I have not started this motor project yet so this thread is for opions and advise.

B16b Ctr motor
Toda Valve springs and retainers
1.8L stroker kit (Toda, or just go with ITR cranks and rods)?
jackson Racing Super charger
AEM EMS

I know I left off all the little stuff but this is just a start. I wanted to get some opinions on the basic set up and what it would take to make it work befor I started getting in to details.

Right now the car is daily driven and I am working on the Suspension and chassis. I plan on using the car for auto X, and maybe a little canyon driving. The car will become a race car after the swap but may still see some street time so the tuning will be somewhat mild (as mild as a motor like that could be).

 

Depending what your compression will be will tell if a supercharger will work safly on your car...

I'd say turbo it but for auto-X and stuff you'd prolly be better off with a supercharger so there is no bust of power through corners and stuff.
I have a friend who has a B16a with 10:1 compression with a JRSC kit and its only on 6psi and it seems really strong above 5500Rpm, Down low its alright i guess, My stock B18b 91 Civic hatch walks him off the line but he catchs up once he gets rollin.

BTW - Do you already have the b16b Motor? If not dont waste your greens for it. Just start off with a B18 block, like a LS or GSR..

 

Well my thinking here is that the B16b comes with a lot of high end power (over 4500rpm), stroking it will bring up the low end and add some torque. the supercharger is just to keep constant power high. I am only planning on running 5 or 6 pounds of boost, and I want to keep the compresion as high as I safely can!

Anyone have any ideas on the valve train? I want to keep the CTR cams but I am not sure about the rest, or my piston & rod combination.

and no I don't have the B16b yet, but this is the motor I want to start with, the question is what to do after I get it?

 

anyone else?

 

early morning?

 

bump!!

 

why not b18c1 built?

still cheaper than type r

 

It's not really the price that matters. I have an 99 EK and I kind of want to keep the CTR theme goin. I want to start with the B16b and build it for road racing. i know that I could just start with a b18 but I love the B16b and I want something different that no one else has, plus I would love the braggin rights. Plus if I start with a good CTR motor and throw in a Toda stroker kit, keep CTR cams and upgrade the rest of the head it should pull harder than an ITR motor.

 

bump for tha love of the B16b

 

another

maybe some tech advice? Where are the forced induction gurus?

 

bump

 

kinda slow.

 

I think everyone else is ignoring you because running uncooled boost on a high CR motor like the b16b is crazyness (although I got some love for the setup ). FYI, I have a b16a/with GSR head running about 10.8:1 CR, with a jrsc. I was set up at 9psi, which made stupid amounts of power, but knocked like a ****. This was on 94 octane pump gas too. The change to a larger crank pulley should get me back down to 6psi, and along with a J&S safeguard, the motor should live for a few months.

The bottom line?
The b16b is a very high CR motor. The jrsc doesn't have many intake cooling options. When you combine the 2 without any sort of race gas, or knock sensor, it's just a matter of time before detonation kills the setup.

i hope you mean a smaller crank pulley

 

AEM EMS has a knock sensor no? CR compresion ratio right? I thought low amounts of boost were good on high comopresion motors. Once I stoke it it should bring the compresion down a little bit. Thats part of the reason I was asking about the stroker kit, the Toda kit might not drop the compresion (I'm not sure, might actually raise it), but I think if I swap in ITR crank, Rods, and pistons that would drop it. If I did that though I'm not sure I would want ITR pistons, could I keep the CTR pistons with ITR crank and Rods? I see what you are saying about the lack of options on the cooling side of things. Is the best i could do a CAI?
I know a set up like this would take a lot of tuning but if it can be done I am willing to spend the time and the money to do it.

 

What is the optimal Compression ratio to throw a JRSC kit on? Maybe 6 pounds of boost.

 

i dunno, maybe im talking out of my *** here, but it seems as though the only reason you want a ctr engine is for the badge on the block. youre talking about getting a toda stoker kit or maybe an all itr internal set up. wtf is the point of a ctr block then? isnt the itr block taller than the ctr anyway, so how would these parts even fit? if you wanted to keep your ctr theme going then keep your b16b stock, otherwise, as someone else said, there is no point in getting this motor.

 

Wow not alot of ppl have detonation problems with a 9 psi setup with stock gsr. Tuned that it.

you wouldnt notice a difference whether it was a CAI or short ram. once the air goes through the blower, its going to be the same temp on the otherside no matter what the temp is on the inlet. i know this because whether i'm driving the car in 90 degree weather or -20 degree weather, once the car/manifold/blower is warmed up, the output is always 150 degrees. as a side note, short ram intakes have been proven to be the best for the JRSC. apparently the blower likes a shorter intake tube.

 

Can we say B16b valve train. the whole point of the B16b is to start with the best motor I can. Therefor in the end I should get the best results. The B16b is a race oriented motor (designed for racing), everything in the motor is better than just about any other motor. Cams pistons crank, even if i don't use some of this stuff I'm sure I can get my money back for it You know anyone that wants to buy GSR pistons? probly not but I could get rid of the CTR pitons pretty easy if I don't want them. I also want to keep the CTR cams, I don't think I will need anything more aggresive. So to save from buying these things to build up a B18 I would rather spend the extra money get a bomb *** motor to start with, buy a balance stroker kit and throw a JRSC kit on it.

Again I am not asking if it is worth the moeny or if you think I should start with a B18 block, I am asking what you think I would need to make it work. If you really don't think it will work maybe offer another suggestion, I was also kind of think about ITB's, but I am going to start with a B16b so all you haters

Actually i believe you said the real reason above (braging rights...imo who really cares)...
If your dead set on spending $5k on a 1.6ltr engine go for. I have nothing agains the b16b, i just have something against spending $5k on an engine just because it says b16b on the block, esp if you plan the change everything out anyways. It's you money, have fun. Spend the rest of you money on tuning, you'll need it.

 

I have gotten qoutes as low as 3200 for the motor, Given thats only the motor assem no shipping or install, how much did you pay for your GSR? It's not just fro braggin rights but its nice.

The one I put on was slightly larger......
Won't a larger pulley allow for slower rotation, therefore lower boost pressures?


edit: on hypa! smaller crank pulley = less boost, not the other way around.....

Actually I believe the B16B is just a destroked ITR motor. So you're basically paying for an ITR motor with less displacement and a higher redline... in other words, less power but possibly more high-rpm stability. Instead of spending tons of money on a stroker kit, buy an ITR motor in the first place and get a stroked version of the B16B - save yourself time.

Like hypa said, high compression ratio in combination with a non-intercooled/aftercooled setup usually equals boom.

Now, as far as your saying "It's what I'm gonna get anyway, yer all just haters" - you asked us. Do it if you want to, but it probably won't work too well... but if you're going to do it anyway, why ask?

hey at least you figured it out before you installed it
