turbo for a 95 DX coupe?

I suggest a B18B or B18C or H22. I like the B18B1 LS perosnally, but thats me. After I put the LS in, there was a considerable increase in performance. The car was much, much quicker in every aspect, about 35% more hp and torque. You'll be happy with a swap like this, trust me. But whatever you do, my syuggestion is swap in a new motor. PWMAN is right, the D15 is the most weak engine, the internals are weak. It's Very Very easy to blow up the engine or snap a rod. Also, it is possible to put an LS auto in your 95 coupe, it's a lot of work, but I know from personal experience it can be done. Of course, I recommned just buying a manual engine, tranny, and ecu and swappin that in while converting it to a stick. The LS auto was a lot fo work to pull off (but if you want to keep the caran AT, it's worht it)

how much did the b18b1 run you? and how much horse/ torque? My D15b7 with the 102hp and 91torque is good for right now, I'm not really a speed freak, but swapping is very interesteing and I'm a few months away from paying off the car.
oh and my car is auto is it a big deal to change it to standard during the swap?

It cost me qbout $2500 for the engine, tranny, and ecu with 23,000 miles on it. Plus it included a 12,000 mile warrenty, so it was a very good deal. I have heard of people being aboe to buy the parts for the swap cheaper. $600 should be appropriate for a labor charge for a swap, so add that to the price of the parts and there you go. The B18B1 puts out 142 HP and 127 FT/Lbs of torque stock. Add a CAI, exhaust, and header and you should be good for 10-15 more. The LS is a very good engine to start with too. It has the best tranny for tourbo apps, due to the longer gear ratio's, which help keep the turbo spooled longer. Also, it can handle about 12psi of boost on satock internals, most other can only handle 8psi or so. Also, some people go the LS/Vtec route. If you opt for that, it is matting a B16A or GSR head to the LS short block. In this swap, there are a few important things, first, don't rev the enigne about 7,000 or so, even though you have Vtec. YOu should still be in the 160hp-170hp range, but the LS block isn't made to hand;le 8,000 rpm revs. If you build up the internals, it's a differnt story. Second, a lot of people who have no bussiness building an LS/VTec build them. A bad build will die quickly, you need to make sure it's built but someone who know's how to do a LS/Vtec properly. Just because they can swap in an LS, doesn't mean they can do an LS/Vtec. FOr your last question, it really woun't cost much more to swap in a manual once you are doing the swap. I know the who did mine knows his stuff, and he doesn't charge too much extra. Everythign is out, so it's not that hard to do it. It takes a few days, but don't worry, if you do it with the swap it should be economical, it's not a big deal to change from AT to MT at this time. Also, it is possible to swap in an LS automatic into your civic if you want to. Most people don't want to try it, but Tim Anderson of Performance LAB in Kirkland, WA (near Seattle) has done it, and did itr very well. I know he doesn't charge too much more to swap in a manual while doing a swap, plus he usually puts on a CAI and I got a 12,000 mile warrenty on my swap from his shop, with documented mileage. If you want to go fast and like turbo's, the LS (B18B1) is differnetly your engine to get. You should be able to get with 250 HP on 12psi onm stock internals, and I assume thats the type of performance you are looking for.

No problem, that's what we're here for . I am always glad to help a fellow enthusiast when I can. Let we know how it goes.

I slapped a turbo on my 96 hatch. pulled pretty good on the high end. i was boosting about 8-9 psi with a jdm 3000gt intercooler (blew the head gasket 5 months later haha) . i had a hks manifold and a kkk k26 turbocharger mounted on that. the bad part about the setup was the design of the factory intake manifold. down draft manifolds are a bummer. other than that, i had alot of fun with the turbo. i was taking on integras and what not. don't expect to beat any car with a dohc vtec motor. you could really tell the difference with the turbo going uphill. AWESOME PULL! just keep an eye on your boost level and most important, you water temp guage. expect to break something when you turbo a honda.

I wonder if the whole 3 page thread or just the first few posts was read and answered, becuase it sounds like the post is refering to a stock d-series engine, nothing is mentioned about a boosted LS. Only a "DOHC Vtec motor" is mentioned, nothing about boosting an LS. He says a DOHC Vtec motor wont beat any car (again, it had been asked about boosting a b-series, not just stock n/a b-series). 2 points here. First, read the pervious posts please, you'll see he asked about an LS and turbocharging an LS motor. The LS is a non-vtec DOHC engine. Second, I assure you, a 250 HP Boosted LS will take out plenty of cars.

As I said earlier, 12 psi on the LS engine is fine. Don't go reving the damn thing up to 8000 rpm or anything, an LS shouldn't go higher than 6800-7000. Also, if he had a SOHC D-series, 8-9 psi is pushing it a lot, that really shouldn't be boosted past 6 psi of so. Most DOHC B-series can handle 8psi or so, as I said, the LS can go up to 12 psi on stock internals. With a proper set-up, you shouldn't have water cooling problems or anything. If you are worried, drop the a/c and put in an integra radiator or a fuildyne for an integra, plus a 1.3kg/cm2 (18.5) psi high presure cap, that will help keep the engine cool. I think a lot of people run into problems with honda's and turbos by A) running too much boost, B) too much c/r for the boosted engine, C) rev the engine too high D) inadiquite fuel supply, I can go on. But in general, put out the money to have a proper turbo kit put toghter (custom kit or pre-made, have all the proper components) and and you should be fine as long as you don't overboost it. Over-reving and high reving will kill any engine quicker, n/a or turbo. Don't get worried. If you do the Turbo right, you'll be fine. And as I said in my earlier posts, the LS short block engine is the best honda engine to turbo. Great Great Block. If you really want a smoking engine, build up the internals (rods, pistons, vavles, springs, etc), do a port and polish, re-sleeve and close the deck. An engine with properly built internals can handle a lot of boost, much much more than 12psi. Properly build engines can handle 25 psi. It's all about how much $$ you want to spend in reference to how much boost you can run without messing up your engine. Since the Honda is a n/a motor from the factory, a turbo on "stock" internals will be a lot less boost (12psi max on an LS) than the EVO VIII, which runs about 19psi from the factory on "stock" internals. The difference? The EVO motor was built from the factory to handle that boost, so of course you can run it. A honda can run that boost too, but you have to build the motor up to handle it. Anyone running 9psi on a stock d-series and reving hard, like a d16, is asking for it., the engine internals weren't made for that. If you wanna do that, put in new internals and build it up.
