which engine is the best engine for little money, fast, durable?

[cre]

The knock offs look exactly like the Walbro... all the way down to the name stamped on the body. I don't know this vendor so I couldn't say. I will say that fueling is one thing where it's absolutely not worth saving $40 by going to an unknown shop or ebay seller. This stuff happens all the time, the big deal here was that a lot of them were tested and found to flow half that of what was claimed and have very high failure rates. There are also knock off Bosch and RC injectors which have been popping up here and there but they're not nearly as common as the knock off Walbro pumps. Remember, there's nothing that's going to kill your engine faster than a fuel shortage.... well short of completely draining the oil and hitting the track.

thanks cre and MA70.. you both just saved me. well gave me a huge tip.
i read somewhere recently about the counterfeit Walbros. im not sure this particular sight is one of the vendors that knock off them, because my buddy bought it from there and tested it and flowed dam near to 255/lph
ive also seen this site be recommended to buy from there. but thanks to you guys i am leery to buy from there.

too loud? haha cre, in your opinion, i am curious as to what fuel pump youll get.
im doing HARD research on everything i get for my build because, well its my first "real" build and not a customers vehicle.
i did look at acouple. but i never heard of them. IIRC 'AirTex' and 'Precision'
they both claim upwards of 255, 260, and one of them i think 300/lph. for 90 bucks.

Well strange thing is, last night I looked up a few sites & couldn't find reference to a "Walbro GSS315" model anywhere, even their own site! (GSS341 was a part number though for a 240lph pump IIRC) just out of interest I emailed a Walbro rep (got an address direct from Walbro site) giving him the link to that site & asking if they're a genuine seller. Asked him to contact me back & confirm if they are or not

Bosch, Aeromotive, Supra MKIV TT would probably be my top 3 choices. I don't have a problem with Walbro, they can just be a bit loud and the concern regarding getting a genuine unit exists. It's not individual shops who do the counterfeiting, it's further down the supply chain so they may not even know.

Also, remember some of them (the knock-offs) flow fine and some live long, healthy lives, I'm just warning you to be careful because of their significant failure rate. Really, if they were just as good and reliable I don't think it would have caused nearly as much of a stir. I don't know how many there are still floating out there as this is a story which broke quite some time ago, but as long as there are suckers out there looking to be suckered I'd bet there are still a decent number getting filtered into the retail market.

That's the main issue with Chinese copy stuff, a lot of it is directly copied from the genuine article & nothing wrong with the actual design per-se, it's the quality control that's lax so far & as you say some are no doubt still flowing away happily, their owners smug for the great deal they got on a "Walbro pump" but would you want to chance it...

Personally, as in my other recent thread, I quite like the savings you can make on knock-off Chinese kit with care and luck & have had some good stuff (most recently a nice "Fluke" multimeter for ?20) and am considering some chinky 1600cc injectors from Ebay as they're about the same price as new "real" 440's and COULD be O.K. & would be all the injector I'd ever need for a big power build in future, but if I did get them I'd be doing some serious stripping, measuring, soaking in 10% ethanol fuel & having flow rates tested etc before use!

Anyway sorry for rambling, perhaps the best budget option for ochowdero could be a used JZA80 TT pump?

Great! i also did that.
i just found a venue that deals with performance whether it be for drifting, racing and strictly drag. so i am going to check em out. see if theyre even reliable.

CRE-i completely understand that. i thank you haha. one because i didnt really know that. and two, i need this kind of information. i dont plan on leaving much loose ends in this build to have engine errors. granted there will still be some but i want to limit serious issues and fuel, is a HUGE thing you should never go cheap on.

im doing alot of research on some stuff. and i wanted to bring up injectors since were on the fuel subject. MA70 you have had a recent thread on 1600cc haha.
for around 400hp is 550cc injectors necessary? i guess the real question is. is that more then enough or just enough?

[MA70-3.0GT]

yeah I can imagine those 1.6liter bad boys would make low-end/idle non existent & require a donkey engine for hot starts haha...

I'm not sure exactly how much of the 550cc injectors you'd "use" to reach 400whp but I was getting occasional fuel cut at 11-12psi on the stock 440's so you'd certainly need to upgrade. As to whether 550 would be more than enough or just enough I don't really know but cre will

Thanks for the vote of confidence.... IRL, I'm actually a complete idiot.

Yes, you can get 400RWHP out of 550's. I think the following should get you there... You'd skip the Lex AFM. You'll need a good fuel controller and possibly an FCD. You do not have to eliminate fuel cut entirely with most FCDs. I don't usually recommend them as if you screw up you could melt a hole through a piston or burn valves when you really push it. 550's are enough though, you're not really asking a whole lot more than you can get out of the 550/Lex combo under ideal conditions (which is as much as 350 and in a couple rare cases a tiny bit over). An adjustable fuel pressure regulator, upgraded CT-26 and better intercooler would REALLY help.
