Forged Performance: 636whp G37 Coupe!!!
 

Hey everyone!

We've been extremely busy here at Forged wrapping up dozens of great builds over the past month or so. We wanted to share one of our G37 builds with the community. Brian came to us with a bone stock G37 coupe looking for a big power build on his daily driver. His goals were simple. Maximum power, pump gas, and no compromises for daily driving. We gladly accepted his challenge and put together a comprehensive build plan to meet those goals.

The end result is one of our highest pump gas VQ37 builds we've done, all while retaining the 100% OEM nature of the car. No check engine lights, no weird startups, no funny idles ... nothing ... and all tuned with the factory ECU. On first glance you'd be hard pressed to find any power adders on the car. But one squeeze of that throttle pedal leaves little doubt that there is a monster under the hood!

Here is a quick run down on this particular Forged Performance built and tuned G37. As always, all Forged Performance engine assemblies are built in house. We never outsource this critical function.

Hope you all enjoy, and let us know if you have any questions.

Damn!

yummy!

Videos or BS ;-)

Unfortunately, we don't have any vid of this one :(

Very nice work, can't say I like the wheels though.

Great results over there!!! I was curious what you guys were doing with a twin pump for a G37!

Very nice to see, thanks for sharing the build details. Currently picking apart the items for my own winter build so I like seeing whats already been done.

I havent torn down my spare VHR motor yet. Are the L19s and the gaskets VHR specific or do they crossover from older VQs?

I can't say I hate the wheels, but I'm not a fan of them either. Everything else is pretty bad ***

Thanks Charles!

The head studs do cross over. The main studs are different though. We opted for the Cosworth head gaskets on this one.

What compression are you running with the pistons? Was the block sleeved as well? Still running stock displacement?

9.0:1 compression ratio in a non-sleeved block. Cylinders were bored .020 over

cool! awesome to finally see some low compression VQ37's with a built bottom end. what boost level were you running for that dyno?

I dislike the wheels, but it doesn't matter. This G's a badazz!!!

This one's a monster! Great job on the build.

I'm assuming a core exchange is part of the engine build process right? I know this sounds weird, but I'm very attached to my core and I don't want to give it up.
