Blow Through Carby Kit
$1745 - Z series kit - Note: photos show some components of the old version kit
$1650 - L series kit
This kit is a blow through carby kit, it is not a "turbo kit", but it allows you to use a carby induction system and "blow through" it with boost from a turbo or supercharger.
For a matched turbo kit, check out our turbo kits.
The blow through carby kit includes all new components, including a new genuine European Weber 32/36 DGV carby and complete high pressure fuel system.
With the appropriate supporting mods (head porting, intercooler, non restrictive exhaust), this kit will support up to 200hp (186kW) - Possibly more depending on how far you want to push it.
The kit designed for Datsun L and Z series engines (L16, L18, L20, Z18, Z20, Z22 & Z24) as fitted to various Nissan/Datsun model vehicles.
This is a complete bolt on kit designed to include every component required to install the carby and fuel system to the engine. This is a kit designed to bolt on and then run the engine, the carby will be roughly jetted to suit your engine, which will get you up and running before fine tuning to suit your engine setup.

Kit includes:
- New genuine Weber 32/36 DGV carb - blow through prep'd and pre-jetted ready to bolt on.
- New Engineered Performance DGV turbo plenum to suit Weber carb.
- New Redline adaptor plate and fitting kit to mount Weber to standard inlet manifold.
- New Bosch high pressure EFI fuel pump.
- New boost referenced blow through carb fuel pressure regulator.
- New EFI metal case fuel filter.
- New high & low pressure fuel hoses and clamps
- All fittings required to adapt high pressure fuel hose from boot to engine bay and install pump.
- Simple to follow fitting instructions with photos that guide you through the installation.
The kit comes will all the little parts that are needed, like gaskets, hose clamps, studs, nuts and bolts, etc. There is no fabrication necessary, it is truly a bolt on kit.
CARB - New Weber 32/36 DGV
The carb is a brand new in the box Weber 32/36 DGV (manual choke option). We specify our carbys to suit the rigors of blow through turbo use, and they perform very well. We then further modify them for blow through turbo use as detailed below. The Weber carb will be roughly jetted to suit the application, but as stated above, you will need to have your mixtures checked and adjusted, preferably on a dyno, before running the engine on boost and chasing horsepower. We also offer cost effective jetting kits to fine tune the carb to suit your engine.

Brand new genuine European Weber 32/36 DGV carb. |
|
High flow cross drilled seat to ensure fuel bowl doesn't run dry during high fuel demand. |
|
Viton tipped needle to allow running at higher than standard fuel pressures. |
|
New custom boost referenced power valve and carb body machining to suit new operation. |
|
Power valve trigger point is 2psi of boost and automatically richens fuel mixture when on boost. |
|
Solid polymer fuel float to handle over 25psi of boost pressure. |
|
Nitrile rubber top cover gasket to seal the carb under boost pressure. |
|
Modifications to the carb to ensure sealing under boost with no boost leaks, including removal of choke butterflies, and primary/secondary linkage engagement point modified. |
|
Re-jetted to suit your application - including float level adjustment and larger high speed enrichment restrictors. |
|
Stringent quality control and Weber factory flow and wet fluid tested to ensure correct operation. |
|
If needed, at additional cost, we can also enlarge the power valve restrictor which is basically the 'jet' size that controls how much boost fuel enrichment the carb delivers. |

INDUCTION SYSTEM
Compressed air from the turbo or super charger is directed to the Weber carb using our v2 DGV turbo plenum. For information on the turbo plenum, click here.

FUEL SYSTEM
For info on fuel system requirements for a blow through turbo setup, and the Fuel Pressure Regulator (FPR) used in this kit, check out Blow Through FPR here.
Blow Through FPR
The kit is based on a Bosch 070 VL Turbo external high pressure EFI pump, which uses the FPR to bring the fuel pressure down to carby levels. The EFI fuel pump used is part of the Bosch Motorsport range of external fuel pumps, and delivers enough fuel for a 300hp blow through carb setup. However the stock 1/4" (6.5mm) fuel return line will need to be upgraded to 5/15" (8mm) or 3/8" (10mm) to run the 070 VL Turbo pump.
070 EFI pump
As the fuel pressure will be around 5-6psi when off boost, and anywhere up to about 25psi when boosted, high pressure EFI spec hose is required. Enough EFI hose and low pressure hose (for fuel return lines) is supplied to plumb up the whole car, from the electric in-tank pump, to the engine bay. All hose clamps, adaptors, EFI fuel filter and fittings are also supplied.
