LS non vtec B18a1, turbocharge?

Question

I want to turbocharge my B18a1 non vtec 1991 integra motor. I've heard they got low compression, and additionally non vtec so they are good for boosting. Only thing is, I want to know what head would work best on an LS block, and also if I need to have alot of work done on the bottom end to have it boosted, or if being lower compression, if it is fine as it is? Also, if I need work done to the bottom end, what do I need done? also if it weren't a LS non vtec, I wouldn't be boosting it. Im getting a gsr or type r swap for my integra and its going to be all motor. this is going into a del sol.

Answer 1

The engine code is b18a1 which is out of an acura integra LS trim.

stock ls motors are perfect for boost as long as the compression is still good and it doesn't burn oil/coolant.

Answer 2

Ok, well first of all the guy saying that LS is a GM engine is thinking of the corvette engines LS1 and so on.

Now, Integra LS engines basically have a built bottom end, so there is little work to do there.  A head that would give you the most run for your money that will go with boost is a b16a2 head.  Its called a LS/vtec swap and its halls major ***(but you have to wire vtec and all that). LS engines are awesome for boosting and same with b16's... they <3 boost. But you might have to prepare the LS head for turbo. you might have to get lower compression pistons and so on.  You might have to fabricate some of the engine bay for the turbo to fit since its a del sol and the engine your putting in is a DOHC Turbo.  And i hope you know that a Del Sol actually is one of the heaviest body types of a civic (crazy aint it? look it up)

get the type-r swap for your integra ;)

Correct me if I'm wrong, but isn't the LSx block a GM engine?
