Hey everyone, so Im trying to decide whether to buy a D16Y8 or D17A2 crate engine off jegs for my 95 del sol, I plan on getting an aftermarket header, 2.25" exhaust(with cat delete), 58 or 60mm throttle body from a B series, with a cold air intake, and larger injectors if I need them. Im not trying to make a lot of power i'd just like to have more than the 100hp it has right now, and hopefully the header, TB, Air intake and exhaust can get the 127 closer to 135-138hp. The D17A2 gets slightly better mileage in the 01-05 civic EX(32/38) than the D16 does in the 96-00 Civic EX(30/35)while also having 7lb-ft of torque more than the D16Y8. Gas mileage is somewhat of a concern thats why im not going with a B series but it seems like the D17 would be better. From what ive read a lot of people **** on the D17 for not being as reliable as the D16 when it comes to building it up but I dont plan on doing anything else besides what I named. Which do you guys think I should use? And would one of them last longer with regular maintenance?

Another Pro about the D16Y8 engine is that it is about $800 cheaper, A nice header will probably be around 400, I've found a exhaust for $340 with Magna flow muffler, then a throttle body is $50-120, so that route would be cheaper

 

A D17 in a 95 Del Sol is pretty challenging. The ignition system is different, no distributor.

 

Leave in stock injectors, you don't need bigger ones and also leave the stock throttle body on. Using a b series, you will have to hog out the mounting holes to get it on and it won't run very good, it will bog a bit.. been there, done that.. I would do the y8 over the d17..

 

Oh ok, from my research a lot of people take the throttle body out of a B series and put it on their d16 without any issue.

 

...and without any benefit most often.

you should first prove it's a flow restriction with data like you would get at the dyno... BUT, the expense of dyno time for a "bolt-on" D-series is a bit of a waste. in my experience without forced induction or non-factory cam specs the stock TB is not going to be a restriction.

 

ahh, good to know thank you

 

Your best bet to do to the motor if you are not getting it tuned for the aftermarket bolts on- get a whale pens intake.. probably the best out there besides a cold air intake which don't really do much.. for all you do, you might gain 5-10hp max with out tuning..

 

OK. the del sol has a hole in front of the passenger tire(behind the bumper outside the engine bay) where the intake gets its air. Seems like it would be a great spot to put a cold air intake. Could I get a cold air intake that is whale pen shape? or do you think the whale pen intake would still work better than the cold air intake?
I hear after market headers can add 10-15% more power but from what ive seen on smaller engines they usually add 3-6hp more hp per every 100hp. I plan on getting a header with 2.5" collector pipes unless id be loosing torque from that. I also hear that exhausts add about 10% more power but I assume Id be getting about the same 3-6hp with that and a cat delete. Then a cold air intake i assume would add 1-3hp. So all together I expect it to add about 10HP, I wouldn't be surprised if it just adds 7 or if it makes up to 14,15. What do you guys think?

 

Id also love to give it a small tune. I dont know much about tunes, like where to go to get one, how much they cost or if you can buy something to do it yourself. But if I could get it tuned for 17-22 more HP thatd be ideal. Do you guys know much about tuning

 

Getting a tune is expensive and highly not recommended to attempt yourself unless you know what you are doing and have the things needed to do it. It would be put on a dyno and ecu reprogrammed. For a stock internal motor and no turbo or power adder is completely pointless and a waste of money. Also stay away from the magnaflow mufflers, I have had 3 types on 3 different cars.. all sound raspy and crappy. Only sound good at idle or low rpm.. want something cool sounding- get a dynamax muffler. Sorry for stupid auto correct.. the intake is called a whale ***** seriously.. they make the motor sound a bit more grunty and breathe very well. Keep your build simple.. do the y8, get the intake,a K and N filter that fits nice in the space you have (they come in all sorts of shapes and sizes), 2.25" exhaust piping- no bigger and maybe a cheap header and your set. Anything else and really your not gaining anything..
One last thing.. keep the catalytic converter in or you'll probably smell your car coming to stops plus your non turbo motor needs a bit of back pressure to run nice.

 

Thank you for all that. Im not super set on the magna flow muffler, I just want something that Isnt loud and doesnt restrict flow much, it seemed like magna flow mufflers dont restrict the air at all but I know they are kinda loud. and in my county we dont have to pass smog after its been done once, it would be nice to just delete it and replace it with a resonator, I personally mostly drive on the highway and am not to concerned about smelling the car. If i am set on deleting the cat do you think it would be better to get 2 1/8" tubing"

 

Also could a stock motor be tuned for about 20 more hp? and why exactly would it be a waste of money. I plan on keeping this swap until the engine goes, i figure if i get it tuned right as i get it itd be worth it to have a little more power for all the years ill have it.
