S14 FMIC - The verdict

johansx · Post by **johansx** » Wed Oct 03, 2007 8:29 am

So I collected my car from Mause yesterday....

Original S14 makes about 100 rwkw

Added Unichip and 3" exhasut - 119 rwkw R4500 +-

Added :
X-force stailess branches R3700
Z33 MAF R1200
Large throttle boddy R340
FMIC 3x the original size + piping R2400
90mm inlet ducting with venturi on turbo R700
gas flowed head R2000
New Unichip ( to fix stalling problem with old chip) R3000
Mause other extras R2700

Total R16 040-00

Ok, so how much power should this S14 produce, reliable, and conservative.

Considering the amount of money spend, that the tuner should tune for the max reliable power, and the max safe/maintainable boost.

Another poll? Previously ran for years reliably at .7bar. At 1 bar the turbo lasted 1 year, but it could only maintain .9bar at full throttle. So with the mods, can it maintain anything higher?

Sorry about keeping you in suspense, I want to prove a point

Remember stock T28 turbo, std injectors.

160 rwkw .... at 0.8 bar

180 Rwkw at 1 bar maybe I wouldn't run this high

Wow, looks like you have a strong camry, congrats

I second Phinx's guess, now stop toying with us and spill the beans or better yet post your dyno graph

Normally when a turbo can't maintain flow on a stock engine it migth even be worse on a modified one, but it depends on other factors too, so it's not always the case.

That is now something learned.Thanks. We tend to forget about this type of detail. chem

but like I said, many other factor does affect it, like a restrictive stock intercooler, exhaust system, boost pipes, etc.

The whole idea of this excercise was to remove restrictions, namely the AFM, throttle body and inlet piping. IC is 3 times bigger etc. So flow should be way better. Air box on the inlet and down pipe on the exhaust the only room for improvement.

So let me spill the beans. On top of the previous upgrade (xhaust+Unichip @ 119 rwkw) I spend a further 16 grand. I would expect the tuner, Maus in this case to try and get the max out of the car, with some reliability off course. Comments like "the Z33 MAF will make a huge difference etc. etc., one come to expect a nice rwkw upgrade. After seeing 2 cars at mr Calibrator with stock injectors nearing 200rwkw, I expected at least somewhere around 150 rwkw. The only comment to Maus was that the turbo does not want to run at 1 bar as Dastek previously set it.

So after lots of work fitting a new FMIC, making pipes etc., spending days hunting down Z33 MAF sensors and getting bigger throttle bodies, the total gain was a whopping 6 rwkw. The turbo boosts only .6 bar. Duh, what am I missing. Spending 16 grand and a lot of my personal time for 6rwkw, the total lack of enthusiasm at Maus does not impress me. Sorry Martin/Kobus, you lost a client! Yes I did not expect you to was my car because of the rain, but the oil paw prints all over the inside, the window that was left open for almost a month leaving a thick layer of dust all over, nobody bothered to even clean the car inside. The oil stains on the carpets are still there when previously you rebuild the engine and dumped the parts inside my otherwise very clean well looked after car...

Anyway, the only thing the new Unichip fixed was the stalling at robots.... but why did I have to buy a new Unichip if clearly the problem was with the previous Unichip. The stalling problem was reported when I originally had it installed....

So can somebody recommend a tuner somewhere around Pta that can tune Unichips and would like to make a loyal new customer in exchange for good service

Preferably somebody that has some SX experience.

Sorry about the long rant, at least I cooled off a lot since yesterday.

I really don't think 200 rwkw on the stock injectors is impressive .

I personally think its called a "lean" condition.

There must be something up with your car Johansx.
Could the Autobox be eating the power?

Yip 200kw on stock is running the injectors at max, all the time. Difficult to tune accurately.

Autobox takes about 4kw. My point is that just the Unichip and the Xhaust at .7 bar made 19rwkw. They should at least have upped the boost from the .6 bar to .7 or even .8. If you look at Johan S14's car, which use to belong to one of the guys at Maus, that car made 155rwkw with exhaust, slightly bigger cooler and injectors with a Unichip. There is no way my injectors are working close to the limit at 125rwkw. In fact I am going to plug my laptop in and see exactly what is happening on the Consult. So, discounting all my other mods, I am missing 30rwkw because my injectors are smaller than Johan S14's car? PLEASE !!!

Any tuners out there .........

Think I will go see Smart Racing ... any comments anybody?
