Tte Supercharger Coupled With Other Mods

[admanirv]

i was told today Hopefully im getting a pay rise next month coz i going abroad odd times to work, so this is a real possiblity, anways...

I wonder how the t sport would perform with,

manifold, apexi air filter, lightened flywheel, sport cats and a.m exhaust and supercharger, must be pusing 165bhp ish i wonder what 0-60 would be and torque?

dont think t sport could handle it all?

[seveer unaek]

You'd only get 165bhp with a chip... 155bhp without. And that's maximum really... BUT it will be much more free revving and responsive. The chassis could handle the power so long as you put a LSD on it (about £600 i think) You'd also be best off with coilovers to sort the handling, and you'd probably need bigger brakes discs, braided steel lines, then you'd be best off with Iridium spark plugs, maybe some upgraded cams etc... but thats running into the £1000's as Jaxx found out, hence the MR2.

At the end of the day, 155bhp from a 1.5 is pretty damn good, but you would need to upgrade the suspension and brakes too. If you want much more performance, you need a faster car im afraid!

[sammyb80]

I was told orginal fuel injectors can handle up to 150hp so probably you need to change injectors.

[earpl]

yeah you'd prolly push 165 maybe 170.

lsd's are about 1500 (i think)

why bigger brakes? its not going to go any faster.

[admanirv]

0-60? probably 7secs id say

[earpl]

erm 7.5/8 i think is more realistic. i'll tell you after september ;)

yeah 7 was a bit optimistic, i though kimi got 7.5 with jsut tte supecharger and a air filter?

[ae111sr]

You need to speak to Kimi who has already done this but she's on holiday at the moment. This is her Yaris in the TOC garage

[earpl]

yeah we didn't know that

i have, spoke briefly on phone and remember her post, but kimi hasnt got a flywheel, sport cat etc only air filter, im sure someone one will correct me if im worng :D

Induction kit (relocated), Supercharger, Exhaust. Think thats the performance bits.

Clarky has the most mods in terms of performance enhancing, just without the supercharger! Pay him £3000 and he'll get the results for ya!

here's something from echodrivers USA site on the limitations of the 1nzfe engine

Turbo charging the 1nz-fe has proven to be chore. It responds to boost quite nicely with a properly sized turbo. But its downfalls are the internals and its engine management.

Lets touch on the internals. First and foremost are the rods. Although quite strong for their size, they are designed for normal aspiration only. A half point higher in compression is about all they can handle daily without failure. Once boost is added to the equation, it becomes Russian roulette as to when they will let loose. You may last eight months with 50,000 miles or blow it the first pass down the street; there are no warning signs. We know this because of the testing of our turbo kit for the last year. The testing started on the Echo then was transferred to a Scion. The testing was controlled and only once was it taken past its set 7-psi mark while in our possession. Its one time high boost pass on the dyno was done to see how much the turbo would produce at maximum efficiency. Fueling and timing were changed to handle this. Every month the pan was dropped and there were no signs of abnormal rod bearing wear. The compression was straight across the board every time. The first motor lasted 6 months with about 35,000 miles. Its life was cut short while at the paint shop. Rumors placed it at the local street races near the paint shop, which they had for 3 weeks. All the baked on rubber in the fender well was the first clue. It let loose on its way back from them. A fresh motor was installed ASAP to continue the testing. The old motor was broke down to find the rod broke right above the crank pin. The dangling rod was beaten into the walls and punctured holes on both sides of the block. The second one let loose 12,467 miles later. It had seen one race with 3 passes at 9 psi. Fueling and timing were also changed to handle this. Other than that it was daily driven. The rods let go again, the same way, only this time it punctured the water jacket and destroyed the head. These engines have the crankshaft offset 12mm to the thrust side of the cylinder bore centerline. This reduces the side force generated at maximum compression, for reduced friction and improved fuel economy. Toyota calculates the offset crankshaft configuration reduces fuel consumption by between one and three percent. Unfortunately, this throws the angle of the rod way out on its upward travel causing the rod to just give up under boost and snap. If there is any detonation or pre-ignition this breakage will occur at an accelerated rate. The movement and breakage of the cylinder walls is the same as Honda’s open deck. Although we have yet to split one, we designed a block guard just in case. This product keeps cylinders from moving around and from splitting open the top of the bore. We are currently designing a forged replacement rod as well as a rod piston combo for high boost applications. The first of the sleeved blocks is being tested now.

Now for the ecu. It cannot handle boost in its stock form. Its timing is set for the stock parameters only. It will not handle larger injectors either. Piggyback or stand-alone management is needed to fuel the turbo properly, end of story.

From what we have seen, these issues probably were found by the likes of Blitz and Greddy long before we did. That’s why the boost on their kits was so low. The stock injectors will supply enough fuel for 3 to 4 psi if the MAF reaches full voltage and gets the injectors to 85 percent duty. Unfortunately you end up with a 15:1 AFR at peak rpm this way. Good for passing emissions but bad for the motor. The RS turbo Vitz has an ecu calibrated for the larger injectors that feed 150 ps at the flywheel which in turn is 127 ps at the wheels. The blitz s/c was turning 122 hp to the wheels without an ecu for the US market. With the ecu (JDM only), the s/c put down 129 ps to the wheels. It seems like the kits are limited to 150 at the flywheel but no one says how long it will last. Our turbo kit produced 144 hp and 150 tq to the wheels. That’s 170 hp at the flywheel. We have worked with several management systems and we will inform the public of the best one for our kit. We will release our kit soon but cannot warranty it except for workmanship. This kit will push your engine over the edge in the long run but if you build it our kit will be able to provide up to 250 hp at the flywheel. That’s 217 at the wheels. With all this said, it is up to you, the consumer, to decide whether this kit is right for you.

Why bother with all that hassle? I'm sure the £3k - £5k could be put to much better use. No matter how many times you sit back and think about it, it just doesn't make sense.

You sell the T-Sport for £6k (example), so £6k + £4k (which would be spent on turbo/sc) = £10k! So what can we get for £10k? MR2 turbo - yes, Celica GT4 - yes, my CRX (2.5k) - yes, scooby - yes, etc.... All of which will be faster then a supercharged Yaris AND you'd have money left over to make them EVEN faster.

Unless you can get the s/c or turbo free, I don't see the logic. A stealth Yaris would be extremely cool - but 7 seconds isn't mind blowing for a turbo car - and is slower then a lot of N/A cars too.

i would have to agree, just make sure you keep it Toyota celica/mr2/levin ect. unless you get luckey like i did, it hard make sence of the cost for a 150bhp yaris

sorry but i have to agree here

i was opting to spend 6 grand on my yaris to get 'maybe' 160bhp?

for 6k i bought an mr2 turbo with 260bhp (as near std) and its more than capable of trouncing a heavily moded yaris!

but then if your after a mega unique powerful and light yaris and arnt worried about burning the $$'s then go for it

haha a starlet gt turbo, seen one other day think there nice looking, and i know im going to get good performance too! rather than wasting loads and loads on a yaris and end up with less than a gt

[seveer unaek]

The simple explanation goes: The Yaris is designed as a city runaround. The T-Sport is a quicker run around that's pretty damned fun.

It is not intended to be a performance car. The supercharger would be great fun though and that is the only thing that's safe for a Yaris to run with as it's fully guaranteed.

Once you start messing with the engine internals, for the money and effort, you're going to want good increases... unfortunatley the Yaris engine won't give them. A Yaris with rear-wheel drive, 1.8 turbo/supercharger, LSD, blah-de-blah would be AWESOME, but it would cost so much it's untrue.

When i have the money... Celica GT4 will be on my drive! It's fast, carrys passengers (just!) i can stick my beer in the boot and it will offer the fun that i like! At the moment, the yaris is all that without the fast bit.

[clarky]

Im not going down the Turbo or Supercharger route for much the same reasons ... I just like making my little Yaris better...

The mods started cause I could and now its become a full time hobby - trying stuff and experimenting. The value for money and economic stuff is all fair enough - I just enjoy it.

Oh and Im looking for a good example of a Jap Spec GT4 to import for the missus ... then I spose Ill start on that.

[Envy Performance Ltd]

Yeah, tbh I think an engine transplant from say a Startlet turbo or MR2 Turbo would probably work out a lot more cost effective than fitting a Supercharger/turbo. Something that has crossed my mind! :o

Although you need to look at what your aimimg at. I as you know am very fortunate to have a 800bhp + Supra for thrills and need a reliable car for winter/wet weather use. I would still like that car to be reliable, reasonably quick, good handling, nice looking and be exclusive and for me the Yaris fits the bill.

I am pretty sure the 1NZ-FE Yaris engine would be cabale of 250bhp if the engine was fully built and the turbo boost was cranked up, but you are talking about a £6k project.
