swirl pot will not cost me 350 quid at all i know that for a fact
heads will be done just its a case of bit by bit, i can get a short engine ready then when i take the engine out get the heads sorted for it but the v3 heads shouldnt require that much work compared to other heads
whats "feature creep"

im like that at the moment, gearbox died so i decided to paint manifiold,,,, now as thats off im doing fuel rails,,,,, as im doing them im gonna change injectors so ill need a ecu,,, as im doing that ill fit a 044 pump i have and my aswell fit a bigger turbo so i then decided to fit a front mount intercooler
infact thats how i ended up wit hks coilovers and whiteline roll bars, links, antilift kit and polybushed the entire car with " as im changing the dampers i may aswell get coilovers"
BUT its a toy and a hobby so why not

how many would consider an swirl pot necessary on a 550bhp road car doing 2-3 track days, and some 1/4 milevents in a year an absolute neccessity?
purley amature and for fun use, no competition ect.
and a single 044 bosch pump good enough?

I'm going to have just one more go at this one.
A standard Subaru fuel tank and pump isn't bad at supplying fuel under trying conditions, such as high speed cornering or quick left and right flicks. There is a surge pot inside the tank.
Despite that, we have seen the occasional one that can suffer from surge when the fuel level is low, often when taking off in a straight line.
If you're going to replace the pump, the way it fits inside the tank is important. The Bosch 044 doesn't fit very well inside the stock holder, being bulkier in all aspects. We've seen some fitments that are actually worse for the system than the stock pump.
Bearing the above in mind, and considering the relatively minor cost (compared to say, an engine) we would normally offer a swirl pot fitting to go with a Bosch pump mounted externally. We fit the whole thing under the hood.
The thinking is this. If you need more than the stock pump design, and by that I'm referring to the Walbro or possibly a Deatchwerks, we can assume you're heading out beyond 450 bhp. If that's the case, then a swirl pot makes sense on the basis that it's likely to be subjected to more G forces than a less powerful car, for a start, and therefore more likely to suffer fuel surge.
After fitting the system we use, we have had no fuel supply issues at all on any car, certainly up to 550 bhp's worth of fuel.
It's possible to assume that because the car doesn't get used much, you may not need a particular piece of equipment. The trouble is, it only takes once. I've seen a number of people go batting around a track until they run low on fuel, oblivious to the effect it's having on the mixture levels, basically the same effect as not running a swirl pot when fitting one could have been useful.
Having experienced and dealt with surge problems in the past with various track cars, I'm inclined to fit one if I think it needs it.
Obviously if it's your car, it's your choice.
