adjustable fuel regulator

[Mick]

Any benefit putting this on a basically stock engine....with chip, TH downpipe, ATR 3inch exhaust, k&N, adjustable wastegate, Throttle body bypass, valve cover breather kit, 160 thermostat ? Any harm ?

I couldn't imagine an LC2 without one.. How would you tune for different weather.. or different situations.. I dont know of one TR owner that has a modified car without one..and I get around.. Everyone hotrodder I know, with a TR or otherwise, has one. Theyre quite handy.

Certainly its appropriate...if you know how to adjust it. Do you have a scan tool? What about an aftermarket fuel pump? Both of these are things that should be on your shopping list long before the wealth of parts you have.

[Mick]

Thanks for the resposes. No I dont have access to a scan tool. I know I need one.

I Guess I should of phrased my question this way: Without upgrading the stock fuel pump is there any benefit of an adjustable fuel regulator. Will the stock pump put out any more than it already does by changing this ? Bottom line ....I dont have the extra money to do both now....would just doing the regulator do any thing or should i just wait till i can do both....

thanks again....

Let's put it this way: You needed an upgraded fuel pump long ago. Although you need a regulator and a scan tool as well, there is no point in adjusting things without a scan tool.

The pump should be your highest priority right now. If you are still suffering with a ~18 year old stock one that was barely adequate to begin with, your car REALLY deserves a better one. Without it, damage may result.

Save up to but the other toys later if you are strapped for cash.

thanks scott. lets reverse the question then, if i do the new fuel pump (which one would you recommend) now leaving the stock regulator would i see any benefit ?

Feeling like a broken record...

"The pump should be your highest priority right now. If you are still suffering with a ~18 year old stock one that was barely adequate to begin with, your car REALLY deserves a better one. Without it, damage may result."

Anyone listening? :nope:

At anything beyond the stock HP levels, the stock pump (when it was new) was being heavily taxed. Not to mention the stock 'strainer' attached to the pump. They often collapsed, and have been redesigned.

For pumps, either the Walbro 340 or the Red Armstron XP (basically a 340 that has been 'tweaked' and tested).

A Casper's 'hot wire' kit is a good idea, too.

Your buildup is coming together somewhat out of sequence. So far its all airflow (exhaust flow) and no fuel flow.

Scott....i appreciate the help....and beleive me i am listening.....
I dont think your hearing what im asking...... :wag:

im asking if i dont change both things at once (fuel regulator and pump) will i get any more fuel flow by doing one or the other.

if i put in a new fuel pump will the stock regulator limit it anyway.....or will more flow through it ??

we already said changing the regulator first wouldnt increase flow because the stock pump is strong enough....

hope this is clearer what im asking

i know you said a new pump should be my priority just questioning if i should do it now with the stock regulator or wait till i can do both..

[Keller]

The regulator is designed to control (or limit, if you will) pressure. However, "flow" generally refers to "volume". Think of that as "capacity" instead of "pressure". I fear that your pump (if it really is the original one with the original strainer) lacks the ability to deliver capacity/volume. By changing the pump and not the regulator, you still may gain capacity/volume. Particularly at high boost levels where it is most taxed.

we already said changing the regulator first wouldnt increase flow because the stock pump is strong enough....

I think you are missing a NOT after "is". The stock pump is NOT strong enough.

IMHO, every TR should have a:

- good fuel pump
- hot wire kit
- adjustable regulator

as part of the initial process in the fuel deliver arena. I'm pretty certain that is part of our recipe.

thanks again...makes sense.....
