Turbo Y4

[VTECnique]

Ok guys, im going to get a loan out, so its come time to boost the EK1. its going for a service some time this week, so while its there, im getting them to do a compression & leakdown test. here's my plan for it. LMK what you think

Stock D16Y4 block & head 170,000km
T25G from S13 SR20 (internal wastegate)
Edelbrock cast iron exhaust manifold (T25 flange, AC compatible, #15031)
Ebay intercooler & piping kit
GFB Mach 1 BOV
Precision 440cc injectors
Walbro 255lph intank
NGK iridium plugs
NGK leads
2.5" ac comp. down pipe
2.5" mandrel bent exhaust
Apexi AFC Neo

8psi daily, i probably wont go over that, but 10psi will be my max. nothing mind boggling, just something that takes good to street driving, work traffic, & maybe a few long distance travels. dunno what to expect power wise, but anything over 100kw im happy with.

I figure if the motor dies/blows/whatever, would be much cheaper to replace since there's alot of them out there. Im using the AFC because of the Y4s 'unique' wiring setup. another reason why i went for the T25G. since the AFC hack doesnt alter ignition timing, i have to manually retard the timing for boost, & when you retard timing out of boost, you lose power/performance, but from what info i have gathered, the T25G hits boost around the 2000rpm range. Boost should also compliment the Y4s longer gearing.

I know i can do this on a budget. Turbo & maybe the manifold i can buy second-hand, the edelbrock manifolds are hard to find used. but everything else will be brand new. I would much rather use new injectors instead of used, i know alot of the US guys use the DSM injectors with a resistor box, but id feel much safer knowing the injectors are new. the exhaust & dump pipe however, have got me a little worried concerning the price. i can get a 2.5" exhaust tubing kit from vrsexhaust.com, which is mandrel bent, i already have a cannon muffler, so that muffler i can re-use, however i may need a new resonator & cat. dump pipe will deff have to be custom, as i plan to keep AC & PS, hence the reason for a 2.5" dump pipe, much easier for the exhaust guys to fab up a 2.5" with not alot of room, than a 3".

i reckon u could do that on a 5k budget if u do the work your self, but it wont be as reliable

[VTECnique]

mate, with 5k i could do the internals aswell.

turbo $100
intercooler & piping $300
injectors $300
fuel pump $150
manifold $300
AFC $500
exhaust dunno

i think i could easily do this with 2k...

yeah, I agree $2-3k is enough for a basic turbo setup

Apexi AFC Neo - dunno if that's the best option. I'd pay another few hundred and get a hondata or PFC, it will save you more headache in the long run

do they make power fcs for d series ?

[MikeyG]

do a minime conversion and bore your block then slap the turbo on

[hisoka]

how much of a loan you allowed to take out.

They are OBD dependent with the PFC for hondas. I beleive it should still work cos i've seen a s15 PFC wired into a b16a.

I know the AFC isnt the best option, however we are talking another 1-1.5k for hondata or chipped ecu. fact is, i can tune the AFC on the fly, saving a few more hundred on dyno/tuning time. the AFC splices into existing wiring, whereas hondata/chipped ecu need to add wiring, new dizzy, etc. imo just not worth it for a D16Y4.

If i were to fully upgrade to hondata/chipped ecu, which is needed to do mini-me, id probably do a swap. fact is im on a budget & can make do with the parts listed above.

how much of a loan you allowed to take out.

Im hoping for 3k. this loan is strictly for turbo setup...

Can anyone give me a vague idea of how much a mild steel 2.5" downpipe would be? im also keeping internal wastegate. ive looked at the edelbrock cast iron exhaust elbow, but @ $180us, im sure i can find an exhaust shop to make me a downpipe for that much in aud...

> Turbo & maybe the manifold i can buy second-hand,

I think many D16 manifolds will be for a T3 flange.
Edelbrock would be one the few choices with a T25.

> Boost should also compliment the Y4s longer gearing.

I think the slightly shorter VTi Y5/Y8 gearbox plus a LSD should be at the top of the list.

> NGK iridium plugs

Save some cash. Go for the NGK copper plugs.

> i may need a new resonator & cat

Salvage one from a late model, performance oriented wreck.
Bound to be some smashed up v8 commodores about.

> T25G from S13 SR20

Fair choice.
T28 wouldn't go wrong either.

> its going for a service some time this week,

If you gonna boost it soon, why service it now?


> as i plan to keep AC & PS

c'mon, harden up.


1) Look for other posts on here or d-series.org about shimming the oil pump.

2) A morosso series 2 oil accumulator is cheap insurance.

3) If your ignition system is still original, it's probably a good idea for a new dizzy. No need for an upgrade, it's just an item which needs replacing and it'd be a good time.

With a good, straight through, rear muffler, and low boost, the stock, cat back, exhaust pipe should be an ok compromise.

A 2.0in pipe will flow 280cfm, which is just shy of your goals (150Hp = 330cfm). You just need to make sure the muffler itself isn't the choke point.

What's the inside pipe diameter of the cannon?

You can get a PFC for around $800 second hand.
Other cheap option is to get a e-manage which are quite cheap and for a D series been done before on a few boosted applications.

Luke's Greddy kit was cheap for like 2k with all the goodies, barring injectors and intercooler. It ran with stock injectors fine up to 110kws or so.
