Fully Built SR20 (S14) in a 350Z using drive-by-wire Z-Fever

[z-fever]

We just started a really cool build. We had a customer bring us an 03 350Z and he wants a truly unique set up. It is getting an S14 SR20DET. We are fully building the engine, making a top mount manifold (custom) with a Garrett 3076 (GT30R) turbo and 850cc inj's. our goal is to do something no one has done before though. We are keeping the OEM drive by wire set-up from the 350Z and running a dual ECU set-up. This will allow us to manage the engine as well as to maintain the VTC, traction control, cruise control, and all factory gauges. The S14 ECU does not run can-bus but the 350Z's does. This is a cool build. I hope you like it.
Here are the pics as it is coming together. I will add pics as the build continues.


and here are all the parts we are using to build the engine:

850cc injectors

New OEM S14 oil pump

New .20 over CP pistons

New HKS 264 step 2 camshafts

New Supertech performance spring and retainers

New Cosworth 87mm x 1.1mm metal head gasket

New SCAT forged rods

New ARP head studshttp://a4.sphotos.ak.fbcdn.net/hphotos-ak-snc7/301868_10150373688798296_296402898295_9772422_5538780_n.jpg[/img]
New ARP main studs

The engine has been sent out, hot tanked, bored .20 over, and honed. The crank was polished and balanced.

The head has been completely reconditioned and the new springs, retainers, and cams are installed.

And of course, this is the heart of it all... the Garrett GT30R (3076) fully ball bearing beast. This power plant should make an easy 500whp on pump gas.
I know that some people will not like this build because we have taken out a perfectly good running VQ35 that we could have boosted and made 400whp or built and gotten more than 600whp. All true, but we have done 100 350Z's just like that. This is something unique that you won't see 50 of at a car show. And the way we are doing it is truly inspiring. I don't think anyone has maintained all the OEM functionality of the gauges and drive-by-wire.
I hope you like it.

interesting

a VVL head would have been really different.

Very unique build. I think some drifters did a sr20 swap in a 350Z awhile back though. A little weight reduction doesn't hurt.

[z-fever]

Yes, there have been a few drift 350Z's built with the SR20 installed but they were not concerned with gauges, a/c, VDC, and other OEM component functionality. We are building a daily driver street car with 100% OEM functions.

I dont understand why use the old technology of a 3076R. You could easily go with a Precision 5857 BB which comes with a billet comp wheel. It would probably make the same power and spool up even better.

I wish I had the money to dream up cool car/engine combos and pay somebody else to make them. GLWTB

What brand are those injectors?

[z-fever]

We have finally built the engine and are getting ready to install into the chassis. Here are pics of the engine build:


Installing the Supertech springs and retainers




The powder coated S14 valve cover. It is polished then black satin coated




Now we are putting the bottom end together with all new pistons, rings, main bearings, rod bearings, ARP's and metal head gasket:






New performance oil pump gears:



Then we installed the front timing cover:


Then we installed the ARP head studs, Cosworth head gasket, and cylinder head. Along with in the intake manifold, valvecover, and custom made exhaust manifold:






I will post more pics after we get the engine set in place and start building the custom engine and trans mounts...

Looks good, but you ignored my question...

What brand are those injectors?

I wasn't trying to ignore you, my apologies....
We are sponsored by Five-O Motorsports and these are their brand. They are a new JECS injector. We started using them this year and have had good success.

Awesome...

We have the engine installed and the engine mounts are built. Here is where it sits. It is very far back and very low in the engine bay.







Stay tuned.. this job will be done by the end of December....

[PyR0NiAk]

That's about how they sit in S-Chassis as well. Only thing that appears to be different is the lack of tilt. It looks good. Keep up the good work.

We finally got her running today. Still have a few things to do but EVERYTHING works. The VTC, cruise, speedo, oil peressure, temp gauge, etc... Drive by wire throttle body functions. It is as though the SR20DET came in this 350Z (except it is 500hp). Here is a video for you to check out:

PLEASE LET US KNOW WHAT YOU THINK!

[Lobo240sx]

Sounds like a girl got sucked into the turbo and screaming for help lol.

500HP SR20 + 350Z = Beast!

[z-fever]

it had a slight leak in the throttle body flange. We had to pull the upper intake and re-machine the flange we welded onto the intake. But it did sound like a screamer!!! LOL....
