How hard would it be to do a B18B automatic swap into a 98 civic DX coupe auto? How much would this cost and would there be a certain tranny i should look into?

Anyone have any info for me

no one wants to answer a post that's been answered a hundred times, that's all... use the search feature.

It's just as easy as any other swap... if you have all the right parts, everything bolts together.

The rear mount will need to be slightly modified to house the auto tranny. Other than that it's pretty straight forward. You'll need an auto ecu... and if you can't source a B18B auto tranny, a 1st gen CRV auto tranny would work too.. so would JDM B16 and B18 auto tranny's. However these run quite a bit more.

If this were me i'd convert it to manual.

I was thinking of doin the auto to manual conversion but then again paying like 800 to get it done isnt too inviting. with the ECU would i need the b18b ecu or what? Which auto tranny would be the best one to get? If I stick with the auto I still want to turbocharge and put nos on the engine. Would this work and what other things would I have to do or what problems would I run into? I've looked at level 10 stuff and I think I would have to use there products to build up the tranny. What do you think?

BTW bbarbulo I have searched many times but havent found a thread on an auto swap.

Jugglez

All the b-series auto tranny's would work. doesn't really matter. whichever auto tranny you go with it would be best to get the stock ecu for it. I'm pretty sure you'll need to maintain OBDII, or a converison harness will be needed..

Be warned, these trannies rob power like nutz, and aren't extremely strong. A level 10 upgrade would be a good idea however it's $$$$... $800 or so for a manual conversion doesn't look so bad compared to the cost of a Level 10 torque converter.

scarlemthug

Really? I thought getting a torque converter and strengthening the tranny wouldnt be that expensive. Maybe I should look into doing the manual swap anyways.

For going turbo and nitrous I was wondering if you had any suggestions. Its gonnna be a daily driver but I want to get above 200 wheel hp. When I was lookin at some of the performance stuff for the 2ng gen talon I saw a turbo that was designed for use with nitrous. Are there any turbos like that for a B18B?

For the build up what would you recommend if I was looking for 200+ HP but good low end torque?

scarlemthug

Is there a way to compromise between having good top end power but goood low end torque with a B18B?

ls/vtec

scarlemthug

That is what I was looking into before but I read somewhere that it wouldnt be a very reliable setup. Is that true? I know the ls engine is a good engine for turbocharging but is the same true for the LS/Vtec?

cosmic zx2

if you're building an ls/vtec... it's not as simple as slapping on a b16 head.... you might want to rebuild while you have the engine apart
if you're still planning on running boost..... buy some low compression pistons (unless you have $$ to burn on tuning)
and BAM it's all good

scarlemthug

I thought you had to use a GSR head on the LS block for the LS/Vtec engine? Im not exactly sure what your recommending. Are you saying when I get the engine and I am strenghtening the internals I should get some low compression pistons? How low are you talking?

scarlemthug

I see you have a B18b in your car. what year is your car and what mods have you done so far. I really want to go turbo when I do the swap but I wanna make sure its gonna be reliable and not guzzle gas like a V8.

cosmic zx2

you can use a b16 head
steve from leitner performance can make it fit

as for pistons... wiseco makes low compression pistons... you car will be a bit slow at first.... but once you go turbo... it'll be all worth it

scarlemthug

Maybe I should become a paid member and talk with altech or leitner about this. When I do the swap I want to swap everything out for something better. So pretty much I want to do a complete overhall of the engine bay. With just the LS block and b16 head and low compression pistons how much HP would I be looking at? Any suggestions on companies I should look into for this. I think I will just get a firm plan on what im gonna do and start collecting everything piece by piece.

Jugglez

only get the low compression pistons if you're FOR SURE slapping a turbo on it. if not get medium compression (around 10.0:1)... this will be ok for N/A and also still mildly boost-able.

Leitner has an LS/VTEC fully assembled (B18A bottom, ITR head, full overhaul) sitting in the shop right now.. drop by and take a look at it.

scarlemthug

Is the engine for sale? what is the engine code for the 98 ls engine? Im pretty sure I am gonna go turbo, Im just not sure when it will happen. When I swap in the ls engine what part should i buy for the engine. The integra or the civic?

Jugglez

No it's not for sale, but if you speak with Steve at Leitner he'll give you an idea of what's involved (and costs).. it's definitely not cheap. '98 ls engine is a B18B1.

What parts are you referring to? Internals? you'll need to get B18B1 internals.

cosmic zx2

nice....you saw my engine


anyways... how much boost are you planning on running? 5psi?
40psi?

scarlemthug

I was thinking maybe something tame for the streets like 10 psi and then being able to turn it up when im racing. Im talking about getting say an exhaust, headers, CAI ect. what model do you buy it for?

What would you estimate the cost to buy everything without labour?
