Topgunz ACE Kit V3 SI A2A Super charger kit for VQ37VHR (Nissan 370z/Infinity G37) might fit older HRs but I cannot confirm that.
Topgunz ACE Kit V3 SI A2A
0 miles on the unit, 3,218 on the kit
-Full replacement internals V3 SI unit
-New drive pulley
-New idler pulleys
-Nismo Red powdercoated piping
-Custom top mount tensioner
-Add-on serpentine tensioner
-2 serpentine belts and 2 blower belts
-Tial QJR BOV with custom silencer
-Nismo Engine cover custom trimmed for the kit
-Rock guard with dust filter
Kit made 556whp on 15psi 93 octane
New tensioner and pulley setups pushed 17psi. Expected to be around 600whp on 93 with proper fueling.
The dust filter on drops boost by 2 psi so you have easy control of power by adding or removing it.
The top mount tensioner also allows easy adjustment to add or remove belt slip for power adjustment.
The kit set up on full kill will push 700whp on e85.
COST OF UPGRADES/EXTRAS:
-$200 for new belts and a spare of each
-$500 to replace every pulley Then $1,000 to get everything inside of the blower replaced. The only used part is the housing.
-Fresh oil in it too good for 5,000 miles
-4 inch intercooler with upgraded QJR BOV ($300 because it was out of stock everywhere)
Intercooler is capable of 1,000whp if I remember correctly.
Source line is still attached and the mounting brackets are installed for easy install
-top mount tensioner Was $650 for custom made. Run 15 psi without it. You can either install it and be capable of 17+psi It’s a fun thing to have knowing you can push more later on, or you can sell it. I believe the last one sold for $450.
-Comes with lines to run to power steering cooler
-Middle silver pulley was a $500 add on for the kit as well
-the nismo engine cover usually runs about $200-$250 but Is being included so the pipes match.
Only thing kit needs is fueling system.
PRICE: $7,000
Selling it to help fund a new business venture. Been sitting in a nice garage since I bought it. Never got around to installing it sadly. With all the upgraded internals on the SC and the pulley to up the boost to 17psi, this is a hell of a kit to get your hands on.
