can someone give me the down and dirty of the LS swap. What it ill take,what I'll need,cost vs performance too. I'm thinking about turboing her, aiming for about 289whp... anyone help me out?

I'll post pics when the car is totaly finished

 

Help, anyone?

 

I'm also interested in this... I want to know more about the LS/VTEC build up with a b16a. Is it true you cant rev above 6800?!?!

Wheres the cheapest place to get a b18b? Is it a cable tranny? What's your DREAM turbo kit on this engine?

 

B18A or B18B? Big difference.
Yes and no. Search, it's all been covered, best in the Integra forum. If you just slap a VTEC head on a non-VTEC block, don't expect it to survive revs over 6800. No.

 

Assuming you have a '92-'95 Civic, an LS swap is pretty straight forward. You have to use the correct stock mounts and you will need a B-series tranny, axles and shift linkage. Any '94+ Integra engine will pretty much bolt in and plug right together. Depending on your model of Civic, there might be some wiring (CX's only have a 1-wire O2 sensor and VX's use a 5 or 7 that may need rewired). Minor issues that can be resolved easily with both the car's and motor's (IE one for an Integra) Helm's manuals. They're factory service manuals and worth their weight in gold.

Cost vs Performance is kinda relative to what you want from the swap. I'm guessing you want to beat someone's dyno figures (specifically said 289 hp) and I can tell you that a stock LS most likely won't survive that kind of turbo abuse for long. Stronger pistons and rods, a beefier clutch will most likely been required for any kind of reliablity. A re-sleeved block and some sort of aftermarket fuel managment stragey would not be asking too much. Remember, 289 at the wheels is approx 330 hp at the flywheel, almost two and half times the orignal output.



Even the most slopped together LS/VTEC will rev above 6800, how long it lasts is a different matter. Some people think building an LS/VTEC is a cheap way to "beat the system" as opposed to buying a B18C1. Realistically, that's not true. In order to build an LS/VTEC properly and that will last, it will cost more than a B18C1. It will be more built, probably faster and, depending on how it's built, more reliable than a stock B18C1 but still more expensive. B18B's are the 1.8L DOHC non-VTEC 140hp engines from a '94+ Integra LS/GS/RS. They have a hydro tranny and are either OBD I or OBD II ('96+ is OBD II). The B18A is the '89-'93 Integra LS engine with a cable tranny (sometimes rated at 130hp and either pre OBD or OBD I ('92 starts the OBD I).

Dream turbo is also hard to answer. If you want pure drag racing power and you have a build engine you would want a radically different turbo from the street guy who never plans to boost more than single digits. Generally speaking, the bigger the turbo, the more power it can produce (more air it can push) but the more effort it takes to spin (turbo lag). Any of the popular aftermarket turbo kits (drag, revhard, Greddy, Apex ...) will have everything pretty well sorted out.

 

You nailed it on the head Andy, as usual.

A few points: A block protector or sleeves and connecting rods are strongly recommended for FI applications on the B18B.

And a lot of people have been having luck with Precision Turbos.

 

This is EXACTLY what ive been looking for ... thank you VERY much... this helps me a ton. :thumbup:

 

Thanks. I'm personally not a big supporter of block protectors or block guards. I'm talking about the piece that you can pull the head off and slide around the cylinder walls. I'd be concerned about that guard expanding and contracting at a different rate than the steel cylinder sleeves or the alumium block around it. They also usually block coolant from reaching the top of the cylinder walls where the actual act of combustion takes place. You'd think you'd want coolant there more than anywhere else. I'd say resleeve or don't bother.

Percision turbos? Have a website for them? I haven't heard about them but I haven't really looked for a long time.

 

ok,thanks umm which version of the civic(dx,ex,whatever) will the LS motor bolt right in with minor problems.. well here will this help im aiming for mid 13's i was thinking h22 but i dunno much about those.

 

Integra motors will bolt into any 92+ civic. H22 is more trouble than its worth, and most people would prefer an ITR swap over an H22
