So after finishing up the Greddy 20G Tuner kit for the HR, I just finished tuning and installing one of the new Greddy 20G Tuner kits for a regular VQ35DE. This one runs with DW600cc Injectors, Walbro Pump, and Greddy Evo TicTT Exhaust, Competition Clutch Stage 4 Clutch-Flywheel, Defi Gauge assortment, and a few other goodies.

Both of the tuner kits now use the 20G turbos, larger one piece downpipes, dump tubes, and larger intercooler.

I was expecting great results from the HR kit, but the results from the DE kit are equally impressive. Some of you have asked about spool up characteristics, so I included a boost chart as well. The 20G spool up about 500rpm slower than the 18G, but still very fast overall.

Here are some pics for your viewing pleasure:

 

427whp on your dyno! Is that safe for the stock revup block? Good job also, damn this really wants me to run more than a weak 374 on dave's dyno

 

Very nice indeed

 

We have run them even higher than that. But I always suggest about 400whp maximum for daily driving purposes. The customer will mostly be driving at the 387whp level.

 

How do you feel the revup motor can handle the 420+whp range? Im 95% of the time on 6psi which isnt even near the 387whp that the 20g kit makes and always wanted a little more power until I build the motor. What psi does it usually take to hit 420ish whp on a DD? How high have you run these revup motors also?

 

I'm equally shocked and amazed!! 427 hp @ 8 psi on a stock engine... whoooooaaa!!
I gotta hand it to you guys, once again an impressive job by FP!! I would like to thank you Sharif, Sandy, Ryan, and the rest of FP's staff for taking up all my phone calls, PM's, and building this tameless beast! Thank you so much, and this is just the beginning of a long term relationship with FP!

 

Nice job guys! Love the wheels too.

427whp is safe...compared to 467whp we did on mine. And when Sharif tore it down, it was still perfect.

 

LOL, I believe that I am the only customer that you have ever had that rides around on low boost.

Great numbers

 

can i haz bigger down pipes?

 

Ahmed, thanks man. You are really going to love the car. Can't wait till you get back into the country.

 

Very nice...

 

Very impressive power on the heartbreaker dyno .

 

Is it me or is their hardly any difference between the two in terms of spool up. Seems like the 20G is a very worthy upgrade.

 

Wow, thats great for 8psi!!

 

It has a slightly slower spool, and not quite the hit that the 18G gives you at the very low end....but definately a very nice spool for the 350Z.

 

Damn I miss those wheels. Sick numbers as usual Sharif.

 

Whats the potential of the 20G's with a built motor?

 

700whp+ easily.

 

I so hate being broke... Great numbers.

 

hav u guys try the 03 04 DE stock engine wth the 20G? I m wondering if it could be safe to upgrade my 04.
