Ben Yip 's ZRE Facelift

Recommended Posts

Bought a Toyota Corolla Ascent ZRE152 / Auris in Feb 2010 MY09


Photos

91.7KW, stock is 70kw, the curve shows the difference between with and without Unichip, most gain in mid range, around 6-8kw, which is substantial. Great on Unichip on 2ZR-FE engine

Stock with cat back only (Graph referenced from another member dutchie101)

Before and after Unichip, plus headers, full exhaust (include high flow cat), NST pulley, intake

Records at Wakefield and Winton for different cars with SAME drivers
https://spreadsheets...u0VP6yGKQ#gid=0


Reasons for buying a Corolla
1. Hate my 1996 Golf, gave me loads of problems and my gearbox problem, WTF
2. Reliable (When I bought it, there was a famous feature called Auto-acceleration in US Corolla), so a bit regret at that time because I do not know that news
3. Weight only 1260kg, not heavy compared to other competitors at the same time, Civic is 100kg lighter, but Civic is small and old
4. Spacious, if I have a family, my wife can still drive, and it is enough space for a baby seat, except my wife has to learn manual.
5. 6 Gears, saves me petrol on daily driving

Why Tracking
1 Play driving simulation for many years, and driven many famous circuit in the world in a F1, WTCC, Ferrari, etc like it got one from Winton, so I can learn the track before I go there..
Click here to watch Driving Game in Winton
2 The game is this professional, Look at the video

You have to know how to set up with tons of theory
3 Driving games help a lot in track day. The way to set up the car, the way to learn and drive the track, the way to prevent locking of the brakes, all the same
4. EBD is so good in tracking, in driving game, I have to adjust the brake bias in controlling oversteering and understeering. To me, Corolla EBD is automatically brake bias. With my back seat removed, I do not need to adjust the brake bias myself. Also in raining, I do not need to adjust brake bias. Most car will tend to oversteer in rain, so a more front brake bias is set
5 FF Corolla with this weight can be faster with FR cars with suitable setup, not big advantage of FR cars with this weight category

Engine oil: Nulon 0w-40 High Performance Synthetic oil
1. To stop overheating
2. Faster in dyno (hopefully), please read some dyno in



Reducing Weight
Remove all the plastic at the back
I will never use 17 or 18 wheels coze they are too heavy, our zre output is not high, heavier wheel will be slowing acceleration. I use 16
I cannot remove the front seat coze the seat belt sensor is hardwiredm otherwise 15 kg can be saved

The end result is very prominent and noticable, especially your tank is 1/4 full, using the power to weight calculator in

http://www.topgear.c...fat-is-your-car
As the article suggest, the track time does not increase because the car is out of balance. Because I am using a coilover, I soften the rear suspension

Default toyota battery is 11kg, if you are looking to lose more weight

A good article of tuning an integra.. The power to weight ratio is the most important part.

Plan to buy Enkei RPF1 16x7, only 6.2 kg each. Price is around 1k including shipping. Work Emotion is too expensive

$255 + shipping + install

Dutchie101 and Johnnieboi have it installed

However, if you don't change the exhaust system, it is useless. For me, I will change the catalytic convertor to the high flow ones because the catalytic convertor is sitting so close to the header

The full exhaust system will be looking around $2k

Wow that's awesome. Thanks man. I've got my axleback done with the Xforce S10 twinloop at the moment and plan on having the stock cat+resonator replaced with a highflow cat and potentially later on will have headers installed.

Haha, I do not want to thrash my current tires, otherwise, I go for 17x7, 16x8 is rare.. I am looking for black or white, not silver

Weight is my main consideration factor, must be under 7kg per corner

Ahhh fair enough but I'm sure those tires will fit the 16x8 also try the site themselves. Here's the chart http://www.enkei.com/size_chart/RPF1.pdf

Accroding to this, I can either go from 5.5 to 7.5, which means I can only fit 6 or 7..

No la, lightweight and ridigity or you end up the wheels being bent during driving in the following Enkei Review This review is quite good

Enkei is not pricy as well

I am already broke after I modify my car and go to track day!!! Start to become addiction

16x8 in 5x114.3 is indeed rare. 16x8 are usually 4 or 5x100. :( I was trying to find a set of shoes for track... :whistling:

Quite the contrary dude. I've had both the Enkei RPF1's and also Rota Slipstreams; copy wheels of Desmond Regamasters'. I flew of the track at 130kph, spun 360 degrees and hit the gravel 2inch from the circuit and didn't even dent or bend ANY of the wheels even managing to lodge a stone inbetween my semi slicks and the wheels.. go figure.

johnnieboi, please beat the sportivo guys. We ZRE owners should not be bullied by Sportivos !!!

This is probably my choice for wheels, Rota R Spec, white colour (because my car is red)

I am stilling waiting for their reply on weight, which I guess less than 7kg

I will also need to buy some red color nuts (my car is red)

Next week, I will change my catalytic convertor to see how it goes. Will dyno later to see the difference, looking for 82kw atw for all mods. Here is my stupid estimation

Base 70kw

Pulley + 2kw

CatBack + 2kw

Headers + 3kw

Catalytic Convertor + 2kw

Intake + 3kw

I had a quick search and have found that they are 7.7kg but i believe they are just under 7kg, no one can really confirm it..

Also the gunmetals come in +40 and white in +45, I know it doesn't make sense but that's what I found :)

They are a good price though,are you still interested in the RPF1's Ben?

I can tell you, very hard decision..I am sure you know how hard the decision is for wheels

TO be honest, RPF1 style is not my style.

Here says 5.9kg

http://www.potn.co.uk/fighter-16-x-7quot-4-stud-fitment-white-with-red-lip-set-of-4-wheels-lightweight-series_p1040558.htm

but here says 7.7kg

Very good price, even with 7.7 kg, I am still thinking whether to go for it..Since I have to pay almost double for RPF1

Dyno done, 84.6KW, around 14.6kw gain over stock, The mid range is quite powerful

the curve is very very smooth

The curve flats out from 5500 to 6000, only 2 kw gain in that range

AF ratio is very stable (no up down all the time), from 12 to 13.3. Thanks to Injen CAI, showing no lean or no rich

The tire was set to 32psi hot for 4 wheels, although the dyno said it is 50psi, so the number of 84.6 might be underestimated. Temperature is 12C

http://www.pumaracing.co.uk/POWER3.htm explains dyno loss

270549_10150704362580697_634740696_19314870_6146600_n.jpg

The guy only gave me 3 runs, First one is 82, second is 84, third is 84.6. because he wants to go home, wtf

Comparing dyno is not that accurate as discrepancies might occur. This is just my estimation

Dutchie101 stock and after his cat back

dynoresults.jpg

I can safely assume the base is 70kw, finding the drive chain loss of my car is a mystery. Every dyno is different, and every car is different. In the following link, the Yaris TS has a stock of 91.3whp=> 30% drive chain loss, Yaris TS is using the same engine as ours and has a engine of 130bhp.

http://www.yarisworld.com/forums/showthread.php?t=10320&page=5

Compared to johnnieboi's one

http://au.toyotaownersclub.com/forums/index.php?app=core&module=attach&section=attach&attach_rel_module=post&attach_id=15718

Our curve is almost the same before 4k, but his curve starts to go flat. Mine one does not. This proves to me that the limitation of exhaust can cost you 4kw in total

Also, at 4800rpm, his one is 68kw, my one is 75kw => 7kw gain, when comparing to Dutchie101 one, this makes sense because he also has similar gain

Comparing to Scion (with Cammy 2.4 engine of 120kw) in a dynojet. Please note dynojet has around 15% drive chain loss, converting to dynodynamic figure, which is (22.8x0.75)kw / 0.85(drive chain loss in dynojet) * 0.7(dynodynamic loss in my car)= 14kw gain.. Not bad for my car

http://www.importtuner.com/powerpages/impp_1002_2008_scion_tc/photo_10.html

impp_1002_18_o+2008_scion_tc+graph_five.jpg

To be honest, a mixture of happiness and unhappiness

Why unhappy

1. I don't know my car drive chain loss in dyno

2. The curve flat out at the top, probably due to my 421 header, but i got midrange

Why happy

1. My friend got a Suzuki Sport 1.6 and his curve was here, same dyno and similar temperature, has weaker mid range and high power. My car has more mid power and low peak range, but his curve keep climbing, and he is 1xx kg lighter

259851_250297234983626_100000100539565_1208978_7385775_n.jpg

2. Comparing to a SuperDave's Sportivo's dyno. Before Lift, I got higher output before 6K

Davidsdyno.jpg

3. For 21K drive away, what do I expect !!!

4. Turbo car, as johnnieboi said, cheating!! Lift to me is also cheating, but I love lift

Based on the figures, I estimate the gain

1. NST pulley=>2kw (proven on 1.5 yaris)

2. Catback=>4kw (proven on dutchie101)

3. Cat Convertor=>2kw (proven on Civic Si)

4. Header=>Unknown 3-5kw

5. Injen CAI=>Unknown 3-5kw

Well, I should focus on tracking, let's beat the other people with this low power beast.

erm dude... You can't exactly compare dyno sheets from different dynomometers as there is a discrepancy of up to 10%. Not to mention the temperature and atmospheric pressures that plays a role on the readings. You say which cars make less power than your car ect, hell my car make 63.4wkw; 20+wkw less than yours but it'll be interested how we go on a race track, with me 200kg+ less..
