Alright lets get started. I'm looking at putting together a turbo kit for an EK civic that will eventually house a JDM D15B vtec. Mind you i don't have the car yet LOL! I'm looking hard for one, but still haven't gotten any replies back from users on forums/kijiji/craigslist. >.< So id like to get started on collecting parts. I would like some suggestions on what turbo, turbo manifold, fmic, chargepipes, couplers, and T clamps to buy. I've been reading and still reading more posts over posting on here D-series as well turbo D16. It seems people who post who are noobs seem to get bashed quick. Anyway i'm looking at putting down just over 200whp. But would like it to take the beating of Toronto's mad traffic and still handle daily driving and track [not the strip, i'll never be that fast]. As well can this be done on the stock JDM D15b vtec or should i consider picking up some motor parts as well. Any advise would greatly be appreciated. On a side note, i chose this block as it seems they are easily accessable from JDM engine dealers.

D.T.P

you can run a stock d15b with a small snail like gt28 and would be at around 200hp. also you must get a good tune to make sure that the motor does not blow up on you. dont get a piggy back system of any sort, its much easier/better if you just get a chipped ecu and tune that. i would recommend getting a car first and collecting the parts after because you might end up with a turbo and no car and if you decide to get some other car then most parts will be useless.
btw dont lock your mind over one motor, you can also pick up a d16z6. 1.5l vs 1.6l=0.1 more displacement. not a big deal but there are other choices.
What is your budget for a car anyways?

I personal don't like D15Bs just because the ecu are near to impossible to find. This might not matter if you are going turbo cuz you would just tune a p28 accordingly. But the D16 vtecs or Y8s? is a better starting point and only a few bucks more though and just as common.

My budget for a running EK [hatch or 4dr only, 5spd of course] is $1500 >.< its not the greatest but it'll have to do for now lol. I'm committed to this model of civic as its what i prefer. As for the motor, i guess i can look at D16 vtec's or the Y8's but where can they be bought? classifieds perhaps?

scrid3r - thanks for the turbo reply

Midori - thanks for the motor reply

I'll consider looking at both, however i'm still going to collect parts.

D15B engine is great for turbo's.
My friend is putting down a little over 200whp on 8lbs of boost. Stock block will handle 7 to 10 psi easily.
I would personally buy a turbo rebuild kit and throw on some eagle rods with vitaras. That way if you want to crank up the boost in the future the block will be'able to handle it no problem.

You can also get a turbo from a talon, they will hold 14 psi no problem, and they are a good little turbo.

stay away from the obd2 d15b's....they have the 2-stage vtec and are a pure economy engine, not designed for performance what so ever....these are the engines that are hard to find the right ecu for.....the obd1 d15bs are great little engines that have the regular vtec and are pretty much the same thing as the d16z6. The stock ecu for this is a p08 and aren't that hard to find.

T-MacK

Might want to throw in definetly stay away from the 3 stage D15b. That thing is the biggest slushbucket you can find for a Sohc.

ok i was looking at the obd2 D15b vtec and from what you guys are saying is stay away from it due to rarity in ecu as well its 2stage vtec. So i guess my next option would be the OBD1 D15B vtec, Would this be suitable and function well with a turbo? As well is there some sort of jump harness for OBD2 -> OBD1? I ask because the platform i'm hunting for is the EK.

T-MacK - i'll look into a turbo rebuild kit. As well i've considered the eagle rods and vitara pistons. Saw it over on turbo D forum that a company was offering the rods and pistons for D15 setup. Also what D15b has 3stage?

spike - which talon turbo is suitable ie. specific years and model?

So far i have a feeling i might be better off with a D16 vtec block as it is easier to work with and parts seem ready available. I guess i'll just have a look on the classifieds. Still gaining more info from you guys and input i'm gaining is helping me lots! As well any turbo manifold suggestions? So far i've seen ebay cast ones and over on homemadeturbo, i saw in the classifieds someone with a D-series ramhorn. Any input on these manifolds?

Midori

You want a OBD1 Ecu anyways because OBD2 is not chippable. There are other ways to tune but I believe Ecu Chipping is preferred.

yes there are Jumper harnesses OBD2 (a,b) --> OBD1

The 3 stage is usually mark on valve with E-Vtec <-- avoid this. They are all stamped D15B on the block.

I believe there is only one turbo talon and that's the TSI model.

There is nothing wrong with the D15B just make sure it is a straight up D15B not some e-vtec one. Also if you buy the D15B sometimes they have LSD transmissions!!! definitly worth searching for as the Si/LSD transmission is the (dare I say) best D series tranny availble.

D.T.P

i am actually building a talon turbo setup for my d16z6. i got the td05h turbo [also known as 14b] came of a manual talon. they have few builds like that on the HMT

As I said earlier, the D15b is great engine for boost, not to mention there are a ton of aftermarket parts for it. I'm building one in my garage as we speak for boost with the Zex turbo cam.

you'll have more fun with a better turbo. 14b's run outta steam quickly on these engines. Something like a t3 .48 a/r would be nice, spool quickly and make good power up top.
The nissan t25/t28 turbo's are decent. I had a t25 with a .63 a/r from a s13 (i think) that I was gunna use on a d16 turbo that was perfect for it IMO.

I have a d15b vtec. Vitara pistons, eagle rods. T3/t4 .60 trim. Full boost is at 5,000 its laggy, but hell its fun as **** on the highway. The power is fun. made 270whp on 13psi! Hope to get zeeman to crank it up safely
