Currently i'm running a 99 EX with a greddy turbo and hondata. The engine is completely stock and running 13psi of boost. The car was dynoed at 220hp and 190lb. This is more then plenty good for me right now.

I'm planning on doing some serious road racing and AutoX and was thinking of upgrading the motor to a b18c when the motor gave out. Now i'm thinking that this D series has been very reliable for me, my car is never gonna win car shows so really DOHC isn't really important. Just looking for some reliable stong engine.

I was thinking maybe I upgrade the internals

9:1 JE pistons, Wisco rods, Crower cam, skunk valvetrain, stronger sleeves, Venom intake manifold, BBk throttle body, Quife lsd, hondata intake gasket.

Should be under 3000 dollars for everything and will be cheaper and stronger to boost then a whole swap. This car will never see a drag strip so i'm not too worried about tons of power. But the engine will be running at full tilt for long periods of time. I'm expecting about 260 wheel hp at about 16 or 17psi with the TD04-15G, maybe upgrading to a TD05-18G.

Would a B series be a better way to go? I've seen complete swaps go for 3500 and up. Or should i just build up the SOHC?

96 SOHC VTEC

Boy, that sounds like a lot of boost for road racing to me.

DOHC-DX

you're running 13psi on stock d-series internals huh.... so, are you trying to blow it up? please tell me with that much boost it is at least intercooled

i'd be surprised if you see another oil change with that motor

I have to agree

loclowd

You got my second on that DOHC

I guess you guys underestimate the D16y8. I've have over 6k miles of abuse at 13psi and over 30k miles on at 8psi. The car sees 8000rpm several times a day.

vtec point - 4500rpm
Fuel cut at - 8400 I've never taken it above 8200 on the tach (proably not accurate)

Oil catch can is clean, hardly any blow by. Engine still sounds great, no ticking rattles. I just change the oil every 3months with Castrol syntec 10W-40. Car does run a bit rich but i like to play a bit safe.

heres my mods list

Greddy td04-15G turbo
Greddy V-spec Type 24 huge intercooler
HKS SSQV bov
Hondata stage 2B-P28 ECU
3bar Map sensor
RC Eng 440cc injectors
255lph Walbro pump
Vortech fuelrail with fuel pressure regulator
Single point ground mod
Greddy Oil catch tank
ES motor mount inserts
9.5mm Plug wires
DC sport shifter with ES bushings
ZEX 7.5lb flywheel
Clutchnet stage 2 clutch
2.5inch testpipe (fake cat)
Blitz dual solonoid boost controller (silver/indglo)

Suspension

Bilistein sports
Tanabe Super H springs 1.5inch lowering
Cusco front lower brace
Neuspeed front upper brace
Cusco Rear upper brace
Comptech rear lower brace
Comptech 22mm rear sway bar
Suspension techniques 25mm front sway bar
protane suspension bushings
Crappy stock tires
GSR rear disk conversion

Road racing a boosted Honda is risky to say the least. If you do go DOHC I would get a B18C1 and boost low like 5-7psi. I still think that would be cheaper than building the SOHC properly and running high boost, and that will give you about 215whp I would say. I guess you would have to get a new manifold and piping too though so it may not be worth it. There is a guy selling a 95 B18C1 here in Toronto for $1900 US.

oldB18EF

theres the effects of 16psi on b20 sleeves... if I was runnin stock internals the highest id push is like 10psi even then id be scared id blow somethin up

Grimm

thats a good deal...

I want lots of boost from a small turbo for the track. TD04-15G isn't a big turbo so 16 or 17psi wouldn't be so bad. T3T4 would be horrible at the track though. VIR and summit point has some nice streches and i don't wanna get walked on by Vettes and Porsches. 250hp safely is what i'm looking for.

Not all boost is the same

10psi from a t88 pushes alot more air then a T25 would at 10psi. So talking psi doesn't really mean much unless we're talking about turbo sizes.

17 PSI from that greddy 15G???? come on.. that can't be true!!!

That sound more like a greddy hotairblower...
they told me that my 15g makes 14 PSI max..

The D-series are killer motors - highly underestimated.

BUT

If you're going to roadrace then you should look into a B-Series motor and leave it virtually STOCK. Revving the **** out of a boosted motor of any kind on a road course is probably not a good idea.

Road racing is best done with N/A motors or supercharged motors. In a type of racing were bottom end is most important turbos are not the answer. When your accelerating through a turn and the turbo lag catches up at the apex, dont be surprised if you fly off the track. Turbos are great for drag racing though. Just my $.02. Good luck with whatever you do though.

I wouldn't be too concerned about outrunning Vettes and Porsches on the track if you are a track newbie. Make learning the proper line around the track and safety your biggest priorities. A stock engined Civic can make it around either of those tracks in good time with a good chassis setup and a competent driver. I also hope you have some brakes that can cope with slowing from 130 lap after lap without fading.

'98 D16Y8- stock
110k miles/45k on boost
10-12psi daily

..don't be so supprised

Tuning has A LOT to do with how reliable a motor is, do not underestimate a good tuner.

VSM EXtasy

actually the max effiency of the td04 is 15psi. But I want to run 17 psi so i would get better mid range. By the time 8000rpm comes around the boost would have leveled off to around 13psi. The Turbo XS unichip and the VW chips do the same. My car is handling the way i want now but in autoX, to be competitive in the Street mod I need to be pushing some good power. You guys would be surprised how quick this boosts, doest really start boosting until middle of 2nd gear but its fairly responsive enough for the track.

My brakes are stock fronts with gsr rear disks with aem pads. I'm planning on a bear 4pot and 1inch master cylinder and ITR porporting valve. Also i have a extra set of Si wheels with Falken azenis for the track.

I hope to see you at VIR in October or Summit Point in early November. You can register here:

I agree..i have over 20k miles on my turbo setup too....and ive never had a "boost related problem" what-so-ever. The d-series motors are more then strong enough. I boost 12psi daily no problems.

There is somebody on this board that was boosting 26psi on a d-series block (stock sleeves with toyota pistons / b16a rods). Now thats a TON of power with stock sleeves. Just goes to show you if its tuned right you can get good results.

I think thats bad tuning personally. Ive seen people with b20/vtec (rods/pistons) making over 500hp on stock sleeves, running 25-29psi of boost. The b20 has some of the strong stock sleeves ive seen.

You must have been misinformed. With the turbo he is running, he should have no problem staying in boost.

Kind of like the Realtime NSX that runs a centrifugal blower? which acts more like a turbo!

What makes tuning a full N/A race motor any easier than a turbo motor? Yeah a stock will be more reliable than just about anything. But this doesnt mean that a built turbo engine cant be safe on a track with the PROPER TUNING.

Too many people assume. I say keep what you have and tune it right!

Riiight. I have never heard of ANYONE using b16 rods in a d16 block. I thought the crank journals had larger diameter in bseries engines. heh, someome tell me im wrong please.

B18C5-EH2

The user's name was "Nathan's Boosted Civic" but he's since changed his SN. I'm pretty sure it was him running MAD boost on a SOHC over in Thailand. I'm also pretty sure he had some custom work done to use B-Series rods in his D-Series block.

Remember, Thailand is home of the SR20DE-T Civics and Supra-engined BMW M3s.

JaeOne3345

nathan had b16 rods with early supra pistons whihc had a 75mm bore..he had very very low compression.

96 SOHC VTEC

Why are all these people posting about boosteed D-series for daily driving? He is not talking about daily driving here people, nor drag racing. The car would see more abuse than ever in road racing and I highly doubt that running 16lbs-17lbs of boost would last long at all. You want a near stock engine when revving the crap out of it repeatedly.
