E30 M3 S14B23 Turbo Project

[Motorsports14]

After over 2 years of ownership, I decided it was finally time to tear apart the powertrain and rebuild to turbo spec.

Made some progress these past two days. Cylinder head is at the machine shop getting a 3-angle valve job among other things. Will post pictures of that as soon as I available.

Changing the core plugs

Cleaned up the journals

Crankshaft in

Spent the majority of the afternoon setting the gaps on the piston rings. Very tedious!

Getting pistons/rods ready

Cool shot of the "S14" engraving on the rods

Wow! Amazing! Anxiously awaiting pictures of the manifold you choose.

Thanks everyone!

Actually, I am planning on building the manifold since the only available tubular manifold requires cutting of the frame rail

This is going to be sick! How much boost do you intend on running? Going top or bottom mount with this? I don't think i've ever seen a bottom mount S14 come to think of it...anyways, great progress!

This is absolutely beautiful man.

Not so sure about the amount of boost I will be running.

I will be going top mount. I know Dinan made a limited amount of turbo S14's back in the day and those were bottom mount. Also, there is someone on S14.net who built a stock internal, low boost motor on the stock ECU which was a bottom mount. IIRC, the turbo is mounted down and in front where the AC compressor usually is.

If you need a manifold let me know, we have S14 top mount jigs. Work is top notch and you will not be dissapointed.

Interesting. Do you have any pictures?

[e30polak]

I approve!

The twinscroll GTX3076 is the perfect sized turbo for the s14! You will have a nice usable power band, with great top end!

Do you have factory cams or some variant of Schricks?

Do you plan to keep the factory intake plenum, or build a custom one?

[T-Rex]

This thread is highly relevant to my interests. Can't wait to see the progress - keep up the good work!

[E30Alpina]

Pm me your email and I will get you some.

My favorite build thread on BFC FI right now! I will build a turbo S14 some day...
