2 turbos on a civic. one big one small. build.
 

First off I am aware that d15b2 is about the worst engine to do anything with. It came in the car that I got for free with a bad valve ($12+gaskets). I looked at it sitting out in the drive for a long time. My background is offroad motorcycle racing and I'm 2010 M.E. grad from Rose-Hulman. I have never had a honda car before and this car is unlikely to ever be plated, at least I dont think I will ever want to pay the insurance on another/this vehicle. I'm really a BMW guy and diesel, small diesels, like the bmw335d.

To this project. I am really going for fun. I am building the setup as cheaply as i think I can.

So to what I am putting together
tuning......
willem burner/moates burn2
moates hulog
turboedit . butt tuning

stage 1
d15b2 stock internals/head
88-91 si intake manifold/mpfi/resister box
PM6-A09 ecu + chipping Kit
TD02u distributor
ebay ex. manifold
ebay t3/t4 turbo
Schwitzer S1 turbo
ebay wastegate
ebay BOV
ebay (GM) 3 bar map
ebay oil filter adapter for turbo oil lines
ebay Gaskets
Homemade Headgasket
Locally sourced hose/conduit/hose clamps/oil fittings
Turboedit/hulog/ecucontrol/freelog for tuning

currently HERE all together and started 6/4/2010. doesnt idle. will run boost for a while then goes into limp mode. 8lbs of boost by 2300rpm during WOT acceleration. boost is limited to 8 lbs for now.

Stage 2 ...
build D16a6 for high boost
Rods <$250
vitaras
cleanup ports in head
high strength studs all around
shooting for 6:1 to 6.5:1 C.R. you can rant about this if you want.

stage3...
RTAWD

stage 4...
grassroots mag. $2011 challenge maybe

time to work out the bugs and tune

holy ---- vids nig nog!

Nice build.

the setup is awesome, and custom... first time ever seen a bi-turbo setup on a honda. keep up the one of a kind setups, its the only way you can be different.

iv seen a few twin turbo honda's / acura's.. but they all had dohc's

Ya twin turbo is a different thing really. I am moving along the best I can on the project. I ended up getting a couple more sst27sf512 chips and a Moates Burn2 so that problem I had with my Willem burner is gone. I also had a really bad idle while using the NG63 code so I tried a NG62 and it was better and then I moved back to NG61 and its almost right. But now the car is hard to start. I need to get an O2 sensor though.

as for my ecu codes. My best guess is the used distributor that I got is bad. I get TDC and CYl position sensor codes. I am pretty sure i have the distributor hooked up right now so the only problems can be bad sensors/wiring to ecu/ecu. If I had started with an mpfi engine i would not have this headache and if I have to buy more parts for this swap its almost looking cheaper to parts out my mpfi swap and buy a complete mpfi engine.

Anybody have or know of D16a6 complete that they want to get rid of. I will be rebuilding it with vitaras and HD rods so it can be a slap worn out engine just want a complete engine and intake system. maybe even a whole car. I'm thinking a wrecked one.

Why did you make a headgasket. Arn't the d series headgaskets super cheap.

Well the real reason I made the headgasket is that I found out it was blown at 5pm on a sunday and I wanted to make it run. But I did want to decompress this engine anyway and my gasket is 3mm thick. To buy a ~2.4mm gasket off the shelf is about $140. So for what I wanted this was cheaper and its Homemade.

nice build. like the home made headgasket. why didnt you purcahse mandrel bent piping? would save you a shitload of fab work.

I had the conduit laying in the shop it was free and what would be homemade about it if i bought mandrel bent tube. Now if you have tubing laying around and own your own pipe bender that could still be homemade. I plan to buy a tubing bending sometime after I furnish my new place

dont waste your money on a tubing bender. tubing benders can only bend thick wall tubing which is not used on auto exhaust. bending thin wall tubing will just crush it. you see those benders at exhaust shops with the kinks in each bend from the benders crush bending the tubing. in order to bend thin wall tubing (0.060" wall thickness) you will need a mandrel bender. mandrel benders start at 20,000 or more. not worth it when you can buy each mandrel bent tubing piece for 10.00. your home made bends are nice but the downsides to it is time for fabrication, restrictions due to multiple cuts/welds and tight sharp 90 degree corners.

@busa4
dont waste you ur time saying things cant work.

Have a new job and the car is going back into the garage. Small turbo is off and to a the local turbo workshop to get rebuild. raidiator that was on when the headgasket blew crasked the plastic tank. plan to move the raidiator to the rear hatch lid. since i'll mostly drive this car offroad anyway the raidiator to too low and in a danger area in the front anyway, plus i can run just about any raidiator when i put it in the back.

Nice work!

Hmm just to document my build im going to add my update.

I'm all done with college for now and have a career now so I bought some parts and got this project dusted off and i made progress over the weekend.

bought:
AFR gauge
NEW DIZZY

What I did so far. I pulled the car back into the garage looked over everything. Looked at the documentation in the car and saw in the log book I had just sat some of the part in place during storage. I gave it a once over and tightened up the parts I found loose. Then it wouldnt start. Old bad gas. I loosen the rail line and pumped the bad gas out. Fired up and drove around the building a little and verified it ran the same as last time I worked on it.

Then I proceeded to swap to the new dizzy. The new dizzy has proper color wires and went on without a hitch and fixed all the error code/limp mode problems. The old dizzy is just some bastard part that has off color wires and is prolly bad anyway. with the new dizzy there was no doubt about what plugged in where.

The radiator is broken and I plan to move the the radiator to the rear window. Free up that space for an intercooler.

Very cool project.

Thanks

I'm actually still actively working on this car but don't have the time to post...at least ill keep telling myself that so I can keep being lazy.
