im only going for the 550 mark (gt35r) is the choice of turbo , i will probably run a piggy back e-manage ultimate i would of thought

Just curious, how well can you run a single with the stock ECU & piggyback? Is the piggyback not having to do some major faffing about trying to get the fuelling correct when the ECU is expecting a set of sequential twins?

 

With the current range of full standaline ECUs (AEM/Solaris/Power FC etc) is one of those not a better choice for the extra couple hundred quid?

opinions vary quite alot , im really not to sure on whats best for the power figure im kinda looking at i would of thought a piggy back would be sufficiant but im a newbie and havnt got a whole lot of knowledge just kinda picking it up as i go along :search:

I'd choose who you want to map the car, then let them recommend the ECU they are best/most comfortable with

I don't think it's fair to say that costs "spiral" when you go single. I think it's more a case of unrealistic initial budgets.

 

If you consider the entire vehicle as a whole, and spec and build the car to be able to cope with the demands that you're going to be placing on it, then as long as the car has been built by competant people there is no reason for the costs to spiral.

 

The problem I think a lot of people have is that achieving the above is no easy feat, so inevitably something gets missed and it only becomes apparent after the build has been done so the costs increase beyond the initial budget.

whats the reason behind costs spiraling though , a decent well set up with a good map should run with no problems , obvioulsy initial costs are a lot

Because no matter how well prepared you do it, you're basically giving a 15 year old car nigh on double it's original power. I doubt there are many people on here who've gone single then never spent a lot (bar running costs) on their car.

 

Also when the conversion is done you'll be looking for other things to change :D

wise words, before i went single i got the car up to as high a standard of maintenance i could achieve this included new intercooler, radiator, waterpump, belts, head off for new valve stem seals, shocks, brakes, fluids, hoses, now if you cant do this kind of maintenance yourself yes it can get very expensive if you have to pay someone, the actual single conversion did'nt cost that much and to this day it still runs mighty fine on a SAFC, then theres the unexpected costs as i soon toasted the auto box so 2 grand for a Boostlogic auto, going single can be done on a budget mate but its not just a case of knowing your way round a set of spanners it also involves some engineering know how, you have to be prepared to spend otherwise you will end up dissapointed with a very unreliable car, if i were in your position you may want to consider a single thats allready been done (to a good standard)

i wouldnt like to buy one already done as that takes the fun out of it for me , but i just couldnt see why if done right first time round why cost would spiral im not one for cutting corners so im kinda looking forward . the other bonus i have is this engine can be on a stand for as long as i want it to be and just start from there also i get oem parts at a reasonble price working for toyota ;)

Don't get me wrong I'm not saying that as soon as you go single costs spiral, but if you go in thinking that all you need to do is get the best parts fitted by the best people then you will have no more hassle after that then you're mistaken.

 

Spiral is probably the wrong word, it indicates a speeding up in money loss, maybe drain is a better word :D

 

I sound like I'm putting a downer on this for you which isn't my intent, going single is mint, do it right & your post single maintenance costs will be less than doing it wrong.

Well you've just answered your own question there. If it were done right then no the costs won't spiral. The problems arise when corners are cut or not thought out. As Paul said, he built his single then bang the gearbox went. If he'd have budgeted for a gearbox that could take the torque going through it then that particular cost wouldn't have "spiraled" would it? ;)

i think as long as people remember these things are machines and they can break so just be prepared for when they do . i will certainly make sure everything is up to the job ie rad, cooler, brakes, suspension which luckily i have fairly good setup already but these cars aint cheap either way its more of an addiction than a hobbie lol
