hey DS.org,

I am new to DS; however, this is not my first Honda, but it is my first time back to the Honda scene and building a D16. last time I owned a Honda was 15 years ago and the K series didn't exist. additionally, I must preface this build with that this is not my first turbo car/build either.

so in august I got a 93 civic si as payment for some parts I had lying around in the garage. I quickly realized that the car needed much more work than what I had expected. the original Z6 was swapped out for a Y5. after removing the head to examine the engine's condition I found that piston #4 rings landing had broken off. the head's cylinder chamber casting was pretty chewed up from the broken landing. luckily, the block seems salvageable with a good honing.

i'm guessing what led to this was that the previous owner ran the Y5 completely stock, including injectors and software, with a greddy turbo kit. the journal bearing in the turbo is pretty much seized.

constructive criticism and feedback will be greatly appreciated.

pics to come soon.

planning on using the OE intake mani and TB. selling/trading the FIC 1650s, since theyre going to be on the overkill side for my goals.

so I am still on the fence with a clutch kit. im def interested in a lightweight FW and something that can support 200-250 wtq.

my heart is pretty set on a S300 setup for EMS.

seems like a nice project to start with. as for the lightened flywheel, there is no need for for one on a boosted appliction

just don't go too light. my car came with the act 11lb flywheel and its pretty good. rpms don't raise or drop too fast. once I drove a crx with a 7 lb flywheel and lightweight under drive crank pully and it was real annoying....

Rims look great on that thing. you planning cut the quarters out?

Im not a fan of my 9lb exedy flywheel its very hard get used to. especially with a stage 4 act HD PP.

If you value your build stock rods and pistons may not be a goo idea if your planning going over 200whp and 7k.
The ARP rod bolts would help for 7k revs.
Who ever tunes this need to get ignition time right or those pencil thin rods will make window in your block.

What is the plan on y5 head, since you are not using it?

Also what are you looking for those 1650 inj. ?

I love my competition clutch!
(stg.2 pushing w/ 225hp 200tq.)
i'm thinking about their stage 4 unit.

Clutchmasters makes some good stuff as well
I only ran Spec or CM on my VWs. my 687whp GTi and my GFs 402whp GTi had spec and CM twin discs.

I want to eliminate as much parasitic drag as possible. light weight crank pulley will be on order soon.

I like annoying this isn't a daily. my TDI is my daily. no gas car can compete MPG wise and I can spank a prius all day in my TDI. LOL

thanks.

ive always gone LW FW on all of my project cars.

goal is 250 whp.

fix the rot before dumping any more into it imo
rot will be addressed before the 2014 summer.

I really like the fidanza unit. I am going with a 2871R because I have one sitting in my garage. it also will be quite laggy for the 1.6 which means low torque numbers. torque spikes is what breaks sh!t.

the other option is a GT35R with an .82 backing. lol. that would hit peak boost and VE by 16K rpm.

I understand this is not an oversquared engine so tq graph/control will be a concern to keep the engine intact. And, i'll be tuning it myself as long as all goes as planned.

im going to mill the Y5 head and building a spare engine to keep on ice.

looking to get 250 shipped or parts for my build. the injectors will come with resistor box too. PM me if youre interested.
