Well it is time to post up my build. I have had this civic for about a year and had a ghetto turbo kit on it last summer and it has served as a good DD. Well the engine finally had enough of the no radiator fan and hot summer days and overheated/cracked the radiator. So i pulled the stock d15 and thats where it sat as of 3 months ago.

Well it is a 91' civic lx 4 door that has been mpfi swaped and obd1 converted using a boomslang harness ( pretty badass). The goal with this build was to have a DD sleeper civic that looks and drives about a close to stock as i can get with 250 whp. I don't like gauges everywhere, slammed cars, and engine bays that have parts that look out of place. Thsi is pretty much a test bed for my own idea's towards turbo honda's. I like oem looking turbo kits and installs so i try and make my turbo kits make sense so there will be no 3" charge piping and T67 turbo's running 3 psi AKA no honda-tech builds for me.

Car:

Old turbo kit installed

The desision to build the engine that way i am has all to do with me being a cheap ass and loving to build oddball stuff. The compression is not to much of a concern.There can't be any worse low end performance then the stock dpfi d15.

Pictures to come of the enigne.

engine D16a6:
- 75.5 ycp vitara pistons
- modded LS rods w/ arp bolts
- polished crank journals
- oem oil pump
- stock head decked and valve job
- Delta 272 cam
- 7.1:1 comp

stock D16a6 head, cleaned, valve job.

D16a6 block, cleaned and bored/honed to 75.5 with .004 ptw. (painted black, yuck)

Internals 9oem oil pump, modded ls rods, bearings, vitaras, Delta 272)

modded ls rod

Ls rod compared to stock d15b7 rod

So for this winter turbo kit i will be running the following

- Garrett T25
- 1.25" sch10 "quick spool" manifold
- 2.5" turbo back exhaust
- modified srt 4 intercooler
- 1.75" hot side charge piping
- 2" cold side charge piping
- 1g dsm bov recurculated
- 680cc injectors
- walbro 255 fuel pump

The point of me building this kit is to have a very responsive street car that will have great power at almost any cruising rpm. Turbo responce being the key here i went with a small diamiter short runner manifold with a 2" collector. This should still flow well up top but give me some nice spool up. The T25 turbo i had from my old turbo kit and should work great on 10lbs. I personally don't like loud bov's so i plan on recurculating the dsm bov back into the intake to quit it down some, and also help a small amount with keeping the turbo spooled.

Turbo manifold:

Well thats it for now, i will try to update as i finish up more things on the car.

Really nice, simple and clean. Who made the manifold, and how much did you pay?

HiProfile · « **Reply #11 on:** December 11, 2009, 06:35:04 PM »

ME LIEK.

The 4dr's are fun cars for DD's, especially in MPFI form. I enjoyed both of mine, and they can hold LOTS of junk if you pull out a seat or three. I only wish I had used a smaller turbo on mine. That t25 should spool up very quick.

Only thing I'd change is the psi you run. If you really want a non-Honda-tack kit, you'll use a 2.5bar+ MAP and do at least 15psi.

gangster.

srt4 intercoolers fit almost like the were supposed to be there. a little rad support cutting and the fit like a glove on an ef. we fitted one to my old 4wd wagon.

Sweet build, man.

Why are you looking for a 60 trim T3 then?

turbob16hatch · « **Reply #16 on:** December 12, 2009, 12:04:28 AM »

Because this is my winter turbo kit, I will have a summer turbo kit that will make more power then this little T25 can put out.

It looks nothing like the EF in this build thread...

Yours looks way shitty, this one is clean...Im failing to see how it looks just like one another.

who did the work on the LS rods you had modded?

turbob16hatch · « **Reply #20 on:** December 14, 2009, 05:49:39 PM »

local machine shop, they do good work. the bushings came from crower.

onlyflash944 · « **Reply #21 on:** December 14, 2009, 06:02:04 PM »

mind me asking how much they charged?

turbob16hatch · « **Reply #22 on:** December 14, 2009, 06:07:34 PM »

It was $140 plus tax. and $40 of that was the bushings.

onlyflash944 · « **Reply #23 on:** December 14, 2009, 06:17:54 PM »

still not bad for a rod that can handle 300+ hp

love the build. i like what you are doing with the sleeper status

take your time, torque everything the right way, prelube all bearings, and keep shit CLEAN. it's not hard if you have a haynes to help you with the order stuff needs to go on

turbob16hatch · « **Reply #28 on:** December 18, 2009, 08:42:29 PM »

yeah i have both a Haynes and a 91' Honda service manual.

i screwed up a oil ring the other night and said fuck it for the night. have another on order. stupid mistake after checking clearances i rushed with the ring compressor and bent a ring. I'm an idiot.

ive done it before too. if it doesn't go in with a few taps of the handle of a hammer, pull it out and check to make sure the compressor has the rings good. it should go in just a little with each tap, if it doesn't then be aware
