I'm mainly interested for the vr4, but I figure this is revalent to DSM's also.

Supra TT vs Walbro 255 vs 3000gt vs stock.

I thought I remember seeing some flow charts or something on the different pumps, can't remember where now.

Basically, what's each good up to? Best flow rate?

Good thread AWD DSM 1! I'd be interested in seeing those flow charts too.

Found it.

Ok, the Supra pump is darn near the best flowing pump but, how much is too much for the (Aeromotive) fuel pressure regulator to return to the tank? I don't want to get this thing on and have it overrunning the AFPR. I would like to know where the Walbro 255 lines up with those as well if anybody has any test data on it.

Either of these look like the right supra pump?

That second one definitely does not look like the correct one (it doesn't look like it to me anyway). The top one looks correct.

Any idea about my question?

How about Here?

That's some good info too.

Wouldn't that depend on your fuel lines, especially the return line? Or am I way off, here?

Anyone know if an AFPR would be a must on a 3/s with a supra fuel pump. I know that most peoplestrongly urge it on the 255 pumps in the DSM's...

I would have to say yes. Being that the Supra pump is a higher volume pump than the Walbro pump, I'd still have to say you need an afpr for it. Don't go the cheap route Rob! It'll only get you in trouble.

BTW, if you need some more cash for this project of yours I may need some more work done in the coming months.

uh oh.... what now?

I've got an itchy wallet and the car monkeys are once again humping my back. The transmission is aching for a rebuild and I really don't want to pull it apart by myself again. AND when the time comes to do the rebuild, it's not going back together stock!

That and I really want to find this oil leak. I know the valve cover filter is leaking a bit but, it can't be slinging all this oil into the curve on the intake manifold. Anyway, I'm buying a beater today. It's Dan's favorite color....purple. '96 Pontiac Sunfire 2.4L auto GT with a gagillion miles for $325. It's one that we got in at work through the police auction in town. Needs a fuel pump to run and that's it. So.....that leaves the Talon open for some downtime.

Herrick Autowerks should be re-opening early next year...

you don't even need an afpr

Good! That'll give me plenty of time to save more money (or tear more stuff up depending on how you look at it) for more stuff. I.E. suspension, drivetrain, and fuel mods.

I hate reading...

So the 3/s cars have a switch for low/high fuel pump voltage from the factory?

Yes but, as it says it's only a type of band-aid.

Rob, I'm serious. Your VR-4 is GOING to run at the track and it's going to cut a 13 second pass. I don't care if I have to fund it myself. This driving around in a Cavalier that says DSM KLR on the liscense plate isn't going to cut it! New house or not there's no excuse with that 3 car garage.

^^ ^^

Thanks Brett.... I think...

FYI, that plate was originally supposed to go on my 96 cobra.

Just trying to help a brother out!

Anyone know the correct part number for the supra pumps? Got a line one one, but the part number doesn't match the others I've seen.

One I'm looking at had a part number of 195130-0172. supposedly came out of a 97 TT supra.

Others I've found have the same number, only ending in -1020

I called the Toyota dealership yesterday to try and get a deal on one. DiamondStarMotorsport.com has them for $235 and I was going to try and get one cheaper. Dealership says my price is $250! Just call up to your local dealership with the VIN of a TT Supra (I found one doing an Autotrader search) and they'll give you a part number. Sorry, I didn't get one or write down the VIN I used.

Why would you pay that when a high pressure 255 is less than half? Are you looking for more than 500 horses?

Possibly

I guess my idea is upgrade the fuel pump once and never have to do it again.

I'm looking for a good deal on E-bay personally. Honestly though, it's probably way too big for what I need.... concidering I'm still running stock injectors.

then do a dual pump walbro setup. that's what the evo guys are doing. AMS sells a kit that could probably be easily adapted to a dsm, stealth, or whatever vehicle absolutely needs to consume fuel at the fastest possible rate.

What's the advantage of the dual Whalbro pumps? I want to be right at the 500hp mark. By the time you buy two Whalbros ($200) and then the kit ($?) plus the modification time (drop the tank, cutting, engineering degree).
