Acura Integra Engine Swap

get the ls and turbo it

[integra818]

Look, before planning on LS/VTEC or Turbo or anything like that...try out an Integra LS and see what you think of the speed of the car. I know a few people who are satisfied with the stock Integra LS as is. IF it's not good enough...try out a GSR...I know alot of people who don't really wanna make the GSR any faster because they're happy with the speed.

No offense but I think you're biting off more than you can chew.

Before doing ANYTHING, read the engine-swap guide thingy on the Honda board around here.

You seem like you have really big plans for someone that seems lost (no offense).

they arnt so much plans im just looking at all the different opitions i have and trying to learn as much as posible about integras considering im just getting into them

If you get any Ls and leave the bottom end alone just throw a DOHC VTEC head on it and get some turbo cams and turbo it you should get mid to low 12's if you know what you are doing. The point of the ls being the prime candidate for a honda turbo car is the low compression ration in the bottom end.


And as for the compression ratio question.....


no more than 9:1 for turbo to keep detonation down
no more than around 10 or 11:1 for nitrous for the same reason
and something like 13:1 for naturally aspirated

if you are gonna build a NA motor sleeve it, get a steel head gasket and good rods and get the highest compression pistons you can get.

[StemarMotorSports]

bottom line it would be cheapest and best to keep the original ls motor and have it built to your specs, drop the compression to 9:1, and sleeve it, arp studs and a steel head gasket, then put a vtec head on it, it really don't matter which. I would probably ust a gsr head but that adds confusion with trying to hook up the intake stuff. so for you i would use a b18c1 head (better flow). get some turbo cams from crower and trhow a misubishi small 16g turbo on it with a fmic, run 18-20 psi and you are well over 350hp, maybe 400hp. forget the nitrous you won't need it. get an apexi vafc an fmu and a upgraded map. tune and go. all this will come to less than you think and you end up with twice (or more) the power and good reliability. this will get you low 12's MAYBE high 11's.

[integra818]

but theres a problem with LS/VTECs...the bottem end was never meant to rev up to 8100 RPM that the VTEC head will take it to. YOU can just get a GSR motor, get an LS crank,rods, and pistons and you're LS/VTEC safe.

Honestly, just driving something with THIS stuff might satisfy you and your need for speed.

If I were you, I'd try to find an RS shell for around $700, buy a newer b18b1 with low miles (inlinefour.com has a '99 with about 40k miles for $2800), slap on a turbo kit at 12 psi for $3500 (maximum), add the standard bolt-ons, and you'd be PLENTY fast enough. Learn to install the stuff yourself. It will save you a buttload of money. Honestly though, the best advice I can give you is to do your own research and take what people say with a grain of salt. You seem to latch onto whatever idea someone throws out next. Find specs, find prices, and like someone said earlier, read the engine swapping guide at the top of the 92+ Civic forum (keeping in mind that at 2,529 lbs for the bare-bones RS, the Integra is heavier than most Civics). Make your opinons based on your own research and you'll be much better off.

[Integra4200]

yeah at this point in taking any ideas from just about any one because i dont know much myself yet thats why im asking around. im trying to learn as much as i can so when i get my integra it wont be so hard to decide what to do and what to get

[Thepeug]

I understand. It's just that some of the opinons on here aren't exactly reliable (that's not to say that mine always are, but some people just post for the heck of it, even if they don't know what they're talking about). Try team-integra.net, clubintegra.com, and edmunds.com for some more info.

[Integra4200]

Yeah i've been on team-integra.com thats a good site lots of information. Very true tho i've noticed some people dont make any sense and just post because they want to. Gets annoying like at first on this thread some one told me to get a type-r engine and turbo it then some one explained that it would be blown in seconds. So as of right now im just trying to figure out what set-up would be best for me.

[integra818]

You're doing the smart thing right now Integra4300, but as I said before...TRY OUT an Integra LS and see just how you like the speed. And also try out a GSR...it'll make your thinking easier, trust me

[Integra4200]

well how am i going to tryout a GSR and a LS with out buying them? I like the idea of a LS and putting turbo and all that on it. or all motor type-r sounds great. im having a hard time deciding on which one exactly

[90tgpblk]

I am some what in your situation. I bought a 94 ls with 104k on it for little over 3k. I know have 130k on it. I did a valve job this summer. I am going to rebuild the engine this summer. Also run a turbo kit on it.
I am hoping that will keep me satisfied for now. Considering I have another project car going as well right now. I hoping this combo will work well and keep the car a daily driver.

[Integra4200]

nice...thats what im looking for a ls for cheap then bulid it up. whats your other project car?

[gen2tegls]

as someone said before putting Ls rods cranks and pistons into a b18c1 engine would be the same as if u took your b18 and put a b18c1 head on .... do u know anyone thats done this or dynos ....whats was the results......like hp and tourqe
