should be something on FLOW RATE if not mistaken oh ;)

DDgreystar,it got nothing to do with the flow rate.the big regulator
tend to withstand higher pressure then the small one.

oops....;)

SARD adjustable fuel pressure regulators for EFI engines utilizes extra light weight diaphragm assembly that provides excellent pulsation dampening; to dampen the pressure spikes caused by high flow fuel pumps and cycling injectors (especially non-factory high flow fuel injectors).
SARD offers two universal regulators, the Type-R & the normal models. Both models comes in either blue-anodized -6 AN aluminum inlet ports with a 1/8 NPT gage port, or blue-anodized aluminum 8 mm inlet with a 1/8 NPT gage port.
SARD fuel pressure regulators are designed to provide the correct fuel pressure for any high performance fuel injected vehicle. The normal model is designed to be used on fuel injected, non-turbo-charged engines, and it is machined from billet aluminum.
The other universal regulator, Type-RJ, is more expensive, and is designed for fuel injected and turbo-charged engines. Due to its boost compensating design, it can provide more fuel under high turbo boost conditions.
As per the normal model, parts are machined from billet aluminum. Pressure adjustment is made easy on both models by turning the built-in 360 degree nut. Both models are made to bolt in the factory location in most vehicles, so installation is a snap!

the big one came with double diaphragm inside if not mistaken and can maintain fuel pressure better than the single diaphragm small one

bro, it means tht we should install the big fuel regulator on the evo? it cost bout 700 man..

well, if you intend to boost high YES.. but if you dont intend to boost up high... a small one will do...

leslie is right,if u intend to go all out monster,the big 1 should be ur choice.
but if u intend to to retain ur stock turbo,the small 1 should be more then
enough.

The article is good Ken.

I've seen 400-500ps monster and they are still using the small SARD regulator. Not on evos but on skylines and those dragster FR cars. Even those on 450-500ps GT3037 turbos sizes or even biger still uses the small regulators, SARD ones.

I've not seen nor hear real significant differences which also explains why most on sale and used are the small ones. I think SARD products are pretty reliable so my advice is if you got the budget, take the big ones but if not, I dun think the small ones will cause any issue to most of you cars.

As long as you dun get a Fake SARD regulator (There's plenty FAKE nowdays) circulating in the market.
