Planned mods for D16y4

[Civlic06]

Hey VTECnique keep us up to date mate, I for one am very keen to find out how you go with this modification as i have a D16y4 and wouldnt mind going down a similar path if you get good results

[VTECnique]

Ok, so while im on the lookout for a new gearbox, still unsure which to get, i see alot of the Y4s motor & box for sale for around $300. wouldnt matter what state the motor was in because i will be rebuilding it ground up with PM6 (D16A6 USDM) pistons to help increase compression. all this i will be doing on my own in my garage.

Now, because of the complexity of using an OBD1 tuneable ecu, ive decided to scrap this path. Im now thinking of using the Apexi AFC Neo. Not as many tuning parameters as the standalones & the chipped OBD1 ecus, but i do believe with the mods i have planned the Neo should run everything quite fine.

In saying that, i was going to go for a stage 2 cam regrind. But now, since i do want every mod to work considerably well with each other, i decided on a stage 1 cam. UP TO a 10% increase in power from standard, the bisimoto level 1 regrind is basically a plug & play cam with no tuning required. it can run quite well with the stock ecu. the AFC should have enough tuning points to properly tune the level 1 cam. i could go with a level 2 cam, but am unsure whether the AFC will be able to handle it properly ei. not enough tuning points.

Now because i will be using the skunk2 IM for a D16, the B16 throttle body will bolt straight up to this manifold. If it cannot, i have a 70mm TB in mind, but would this be too big for my setup?

with these & early mentioned mods, im aiming for around 100kw at the wheels, please do not laugh, if you think this figure cannot be achieved then tell me in a respectable manner. i would even be happy with 90ish kw!

I was looking at a Y8 gearbox for the Y4 engine.Stockwise,I heard it`s the best option.

I`m pretty sure greddy e-manage is a better option than the neo.Can somebody confirm this.

If you do order the stage 1 cam from bisi could you drop me a PM,I`m keen to buy also if not too expensive,this way we obviously can split the shipping cost.I`m on the Gold coast.

70mm is too big.The TB should match the Skunk2 IM,60mm.But there is an issue with one of the sensor`s,2 to 3 wire.Can`t remember exactly...

the d16y4 is a 3 wire IACV sensor

70mm tb is too big mate.
Bisimoto sounds like a good choice.

[VTECnique]

Thanks guys, yeah i thought 70mm might be too big.

Beeza - i know the e-manage is a much better piggyback unit, but since of my budget, yeah you could call it cheaping out i spose, ive gone with parts that can run fairly well with the stock ecu. If i went with the e-manage, i would move up to the stage 2 cam...

Alot of the US D-series guys swear by bisimoto, the only problem being for us is the fact that we have to send our cams all the way over to the united states, $$$ in shipping fees. If only he had a supplier in Aus, now that would be awesome!!

Beez - with the level 1, no need to change springs & retainers either, im quite happy with where the stock rev limiter is, & the level 1 cam produces power between 1500 - 5700rpm.

go hard man i have a d series as well, currently in the process of my build...

some words of wisdom:

keep to what you say your gonna do, or else money will become an issue

[myztery]

Zex/Comp Cams 59300 Camshaft...

i have one if you want it

[Limbo]

i'd say get a PFC rather than the Neo, Plug & play, heaps more functionailty.
And later it can accommodate turbo Or a engine conversion if that's what your gonna do.

[Benson]

Big is not always the best. Do your research then carefully chose your parts

[VTECnique]

mystery - i cant use the zex/comp cam because the Y8 & Y4 heads are completely different, plus that cam has much more lift & duration to the one im looking at

Limbo - if i had the money to get the power FC, believe me i would.

sorry i forgot your not vtecn
