BGTV8 VQ40HRGA Race engine build

BGTV8

Is my induction system on Sasha's race car engine.

Sasha is doing base mapping for my ECU.

He is THE MAN .....

I knew that's what he was testing for. That is awesome. I can't wait to see the end results.

Mamotorsports. I don't know any details or when its going or if it ever will come into production. But it will be in the works very soon. This should be an interesting year for the NA platform

Induction system shipped from Canada today, flat-shift gear knob ordered

BGTV8

OS Giken TR2A clutch and lightweight flywheel arrived. 184mm of low-rotational inertia goodness .... Induction system should clear customs by Wed/Thursday

BGTV8

June Update ..............

Porting now done, inlet flow is 328cfm at .600" lift with ITB fitted and WOT. This should equate to near enough 500hp @ the crank and we are hoping for 420+ atw

Engine dummy assembly now started ........... engine porn photos due in a week or so

Geez ....

It has been over 12 months since the last post I made.

Have added some photo's of the short engine assembly at the top of the thread, the Motec M150 has arrived plus the firmware to go with it from VitTuned, the wiring guy is doing the M150 harness.

Simlply unplug the Nissan ECU and plug in the M150 using the harness we are making. There are 12 wires to go thru the firewall which plug into the harness into the VVEL controller so the Motec takes complete control of the VVEL as well.

I have Jenvey DBW controllers (one for each bank) for the ITB set up, and the flat-shift gear lever (it has a load-cell so the ECU "knows" when I am pulling up a gear or pushing down a gear and can rev-match and auto-blip respectively).

Vit @ VitTuned is looking into dial-able TC so we can tune the TC for full wet track thru to full dry track

The heads are all built but we won;t install the cams until the engine is ready to go.

First step is to get the Motec running the OEM engine (there are a couple of Production Car runners here who must run basically stock who are awaiting my research) and then we put the ITB kit on the stock engine with the QBE69G sequential and get all that running and then we put the full-fat engine together and put it in the car.

The schedule for this project has blown out because I have been working at the other end of the country since Oct last year and it has left me with zero free time. Just starting to get that project into shape where it is delivery to schedule so I can now afford to shift focus onto personal projects like this.

I hope to hape the Motec running the OEM engine in a couple of weeks and progress to it running the ITB kit and 69G behind the OEM engine before Xmas and the full-fat stroker will go in early in Autumn next year (March/April)

I'm jealous.

Update

So finally got our patch harness finished and bench checked. Has only take 14 weeks ............... Jeez .......
Car on the dyno tomorrow to run the VQ37VHR engine with the M150 and and tune for best output, and then we will fit the ITB kit and see what difference that makes. I'll then bring the car home to run for a few weeks before sending it back into the shop to upgrade the fuel system, final assembly for the new engine (heads not yet assembled and on the short yet), fit the new engine and Quaife sequential, run the new engine in and try a few power runs to see how close we have come to target.

This project has already run for 2+ years ........... pharque

Rusty

Seems like this project will be finished when you're in the grave, and handed over to the grandkids.

I'm determined to get it finished .... problem is that I'm working 2 hours flying time from home and it chews up so much time.

My Z34 has been in the shop since late June and was supposed to be all done by now but the guy doing the patch harness has been the delay ... he suffered a serious illness and then had a bout of regret and wanted a waiver because his harness was going into a car that would remain registered and that caused him a pile of issues. I had to draft up a waiver to go onto his invoice before he would release the harness .....

Anyway, on the dyno this morning with the M150 running the standard engine and then we'll put the ITB kit on and find out just how constrained the OEM engine is on the inlet side ...

I'll take the car back for 6 weeks to drive it and debug the Motec is required, and then the real fun starts with completing the 4.0 assembly and fitting it.

That is the real reward.
