That goes without saying for sure!

Either that or people would just swap the v6 in...he he he...

How much market would there be right now for 5s parts?

[mrturrari]

Yes, I am sure people would still be swapping V6s into them.

Well it's a catch 22. Most who have the 5s couldn't afford the turbo so they don't have a lot of money for upgrades. And of course since they can't afford upgrades there is less demand which makes the upgrades more expensive and then even less can afford them.

I am talking strictly NA here but if someone could offer a kit with real cams (250-264*), preprogrammed fuel control (SMT6?) with injectors for a reasonable price. Maybe offer a few programs for stock exhaust vs headers and 250 vs 264 cams. The problem of course is that the they would need a large order to get the prices down and I don't know how well the NA community would respond.

Most people don't realize it but the common cams that Webcams offers and the ones that others make as regrinds actually limit their future power because they are designed not to exceed the capabilities of the stock fuel system. So to get real performance you must replace them all together.

The 5sfte setup puts you in the same boat as guys who put a t3/t4 on their 3sgte and unplug the map sensor to get that extra boost. You are totally relying on the boost controller and waste gate to do their job. If something fails then you have a problem. Is it ghetto? Hell yeah.

Blackbob makes a good point though that more and more people are trying to turbo their 5sfes. Most I have seen lately are teenagers who have friends who have done it on their cars or have seen others do it on the internet. Most of them can barely afford to buy the turbo kit much less an SMT6 or EMS and pay someone to tune it. They will find a source for information whether it is accurate or not and do it anyway.

Yeah and last time I checked aren't broke teens how the import thing started ? Guys hwo couldn't afford the high powered muscle cars their friends had. And yes I agree if you can't afford the right way then don't do it. My only problem with that is the "right way" isn't how this whole movement started. That's why you have susyems like megasquirt that work on the broke trail and error types. Me personally I know enough about engine management to swing it. However,something with the ease and affordability of say a SAFC is just,in my book,the way to go. But at the same time I understand from a tuners standpoint how dangerous playing roulete with your engine can be. But there has to be a safe more affordable way then EMS

^ should i mentioned SMT6 again?
i have always said its the next best thing to a standalone because of the feature list.


As far as cams go i can work with fairly affordable regrinds roughly 400-450 a set. I am working on lots of custom products for the v6's and have thought about bringing in some pistons in the future.

I think V6 is the next step for me too if I can get more info on it. But for right now the 5S for me is where it's at. That and I'm am a nissan guy so I feel kinda wrong in toyota country. I've never heard of the SMT6,what's this again ?

[Weasy2k]

its a fully tunable piggyback system
Ignition can be retarded and advanced
Fuel trims can be done for larger injectors <--all the s-afc can do
Run set point output for different htings (control relays for N2O, shift lights, WI)
Additional Injector control (up to 6) for fuel or water injection
....thats to name a bit

[Enthalpy]

The SAFC is an absolute JOKE compared to the SMT6! The SAFC is an alpha-N controller, which is a horrible way to control a turbo or supercharged motor. It's very existence on the market indicates people have more money than they do EFI sense. ...And these are people with very little money!

[blackbob]

Where can you get this SMT6 ?

[Weasy2k]

Me
Im a dealer for Perfect Power...only because i believe in there products vs the other stuff.

Oh yea you can (if you are an avid tuner/electronics person) remove stock cold start injector as well.
and if your really good...remove afm and go to a maf or map

That I can do,but,remember I am in the Navy so it's all about finding the time to do it.

[Weasy2k]

yep it takes time as you have to compare the afm voltage to the map voltage so you can mod the map voltage to match the AFM voltage at each cell Time but if you want to remove the AFM thats a cheap way to do it and it works VERY well I would personally go for a MAF tho as it gives better airflow readings to the ecu...

Can you grind a set of 93 5sfe cams to have .350" lift and 264 duration and still be within the range of available stock shims?

[Weasy2k]

whats stock? 264 is easy as i do that with all the v6's

Damn I wish I lived closer to denver!

[Enthalpy]

I do too!

I believe it's somewhere around 220-224 degrees AD but I am not positive. Stock lift is about .315" so it might not be possible. 93s could easily be ground to fit a 91 though. I have a set of 288s for a 91 that was done this way. I think I need to measure them to see. If it's not I may have no other choice then to have them welded then ground.

[Weasy2k]

there is a strong chance i can do that...a very strong chance. I jsut need a set...i have planed on produce 5s parts for a while and may do so in the very near future....
pistons, rods, springs, valves, cams....

[scooterman]

im mega squirting my 5sfte and going distibutorless. Please no comments on difficultly blah blah. I just want to know if anyone has come across or knows what the stock computer has for a timing advance map.

sorry i was searching in google and didn't notice this said 2-1-07

my bad sorry for the dead thread revival.

[Enthalpy]

No worries. It's a question asked a lot.

If you use the right tools to tune the car, you never have to know the factory advance map. It won't do you much good at all. You will need to tune your EMS for your individual motor to extract all the potential the motor has to mechanically offer. Potential, as measured by mileage, power, responsiveness, ease of starting, etc. You can achieve all of these things without detonation, overheating, bearing failure, and the other earmarks of poor mapping technique.

If you live in/near Denver, CO, I can show you how to do this. With the right tools, it's actually not difficult. Without those tools, you are shooting in the dark and doomed to never extract all the potential the motor has to offer.
