Hi All, For those a bit concerned about the fuel consumption of their car when modding, here is a good consideration to factor into your selection of ECU or modding in general. Here are some fuel consumption statistics I have recorded over the past few months. Experiment constants (Note: this is a real world experiment, so lets not get too scientific about the fuel contents of each top up etc etc) Fuel: Vortex 98 (all from the same pump) Period: 3 weeks Driving style: Daily commute over 3 weeks and weekends. Some may say I drive my car consistently hard. Results 1 – Power FC @6psi ECU: Apexi Power-FC Boost: 6psi Average: 10.48L / 100km Results 2 – Vi-PEC @11psi ECU: Vi-PEC V44 Boost: 9psi Average: 9.72L / 100km Now, it did not make much sense to me when I first plucked the figures into the spreadsheet. The setup remained the same, in fact the Vi-PEC is running more boost and is producing more power than the lower boost tune on the Power FC so how can it use less fuel over the same period of driving?? After triple checking the calculations, I have concluded that one of the MAJOR difference between the two is the ECU is that the Vi-PEC uses closed loop fuel control on cruise and idle, as for the Power FC uses open loop fuel control. This was quite new to me, but the ability to enable the ECU to talk to a wideband O2 sensor and allow self fuel adjustments on a series of self defined parameters is unreal for me!! More power and driving harder with less overall fuel consumption is pretty clever!! Some food for thought. Cheers.

hehehe, now that i have a new clutch, new drive shaft and tuning done. I will wait for till I get new rubber, and also clutch fully bedded in, then I'll be in for a retune. Then I'll definitely be going to the track.

Ahh!! I'm glad someone on there is thinking! :) When you look into what this ECU can do compared to the PFC you'll instantly want one. We're almost done with my one, and i'm sure CHA54 would be willing to offer a plug-in option for corolla! (dare i say at a competitive rate too!)

Check your fuse box. :)

Looking forward to the flexibility of this ECU, expecting much much more control than a Power FC. Anyone interested in a plug and play kit for the 1zz Power-FC?? :D

I would say its the wear from poor or aggressive tuning, and not from force induction specifically. To give an idea... I have had the same supercharger and now running a turbocharger Supercharger - approx 16,000km (can't remember exactly) Turbocharger - approx 9500km Motor has done 104,000kms Had the same clutch from 36,000km IMO, the motor does fine with good care, tuning and i am by no means a 'granny' driver. Wanted to clear this up before everyone starts to think its force induction that kills motors. :) Cheers.

looking fast is a great way to attract cops. "Mate, i saw you going fast, you looked real fast." This thread is a crack up kids, keep it up! :) its great entertainment

Some more progress!! Started painting the complete cooler pipes and some more progress on the rest of the plumbing! :) The progress in the bay... New Magnaflow 5" mid muffler Should be quiet!! Here it is fitted All bits painted and fitted!! :) Heat shield in place! This is a view from bottom up to show the space available away from the brake hoses etc. The oil return, heat wrapped dump (with added bracketing)

Experience You get to learn a bit when you have been mucking around with the same car for over 5 years and it also helps when you have friends that have even more experience up their sleeves. :) Other than that, it requires a lot of reading and experiementing to get it right, also other forums are great places to learn what other have done wrong and understand what's required so you don't fall in the same trap! Cost Well, i can't really put $$ to the project right now as most of the cost has gone towards the time spent. I will try and itemise things for everyone when i'm done, but to give you an idea how hard it is for me to work it out, i have bought enough gear and raw materials to build the same kit at least twice and another 2 or 3 kits for another motor like a 4AGE 16V or 20V Power I don't know what i am expecting to be honest, i don't even know how much boost the stock actuator does on the 2008 wrx turbo. :) lets say i'd be modest and estimate 150kw, but would expect full boost before 3000rpm and mountains of torque, and hopefull not spat rods... :P

Getting some important stuff done today and something a bit more interesting. :) Before we get started, incase people have wonder who is acutally doing the welding. Here she is! Oil pan mods for the oil return on the turbo. An steel AN -10 bun was used for this job. The inside was a pain to do, but she did a nice neat job! The path of the radiator hose has been changed to provide more space for plumbing. Silicone radiator hoses are used. The intake pipe with rampod is mocked up and test fitted with the first mock up of the 'easier' cooler pipe Here's another view with the start of the turbo outlet pipe Getting there! :)

Why has everyone gone quiet? its ok to ask questions people! :)

haha! that knead it reminded me of that H7 mount you had to make! that was gold! As for the intake, i think i might leave it alloy, but rub it with a bit of polish and keep it a brushed looked.

Got the ceramic coating sorted today for the turbo manifold, with a turned up bung for mounting the heat shield. (note: bottom one is for a 20V) Here's what it looks like on the motor Heat shield is made from ACL heat shield sheet, and mounted with bolts on the manifold and dump pipe Intercooler mounting is also sorted!! :) This is what it looks like in the engine bay, test fitted. Surprise! everything fits. :)

Jason and Jason, joint project, still a DIY! Purcell Performance as far as i'm concerned. 2 brains is better than one, put 2 very resourceful people together this is what you get. btw, i thought wei wei was the Knead it king. :P

Lucky you're in QLD. :) UQ Engineering Library, you'll be amazed at what you can find there!

Some more progress. Rotated the turbo housing today to suit the positioning in the bay. This involved turning up new mounts for the wastegate actuator, and welding them onto the housing. Here's a test fit of the turbo manifold, it was a really easy fit, easy access and provided much more clearance to brake lines and definitely steering rack too. With the turbo in place... this shows why the turbo housing was rotated. We made a start with the dump pipe and couldn't stop! :) Note the tight wrap around to clear the steering rack, power steering and misc bits that are there... :) Side view...

hehe, now now silva, DIY is doing stuff yourself, the mill and lathe aren't CNC (still DIY if they are). from the items you have listed no wonder you guys are worried about hurting yourselves when doing DIY. This is DIY the proper way! :) Turbo is a TD04L out of a 2008 WRX. :)

Been a busy weekend!! Several hours both days have the turbo manifold pretty much complete!! :) YAY! here are some piccys... A shot of the collector and the space we're working with... the idea is to make it as compact as possible. Another runner Yet another... All of them positioned! Welded This is what the turbo looks like on it... Final prep before sending off to get coated... facing! DIY FTW!!

Yes jimmy is just jealous he cant ride cool like a rice bubble like us ..... but yet he's stuck in a female hair dressers car :lol: :whistling: now now bill, we don't need all the celica boys to come on here and start a b!tch fight! i love our bubble!! only if the rear suspension setup is a bit more sensible... :(

oh no no, i think bill and i mean the intercooler bits, as for the turbo outlet/inlet will definitely be different to bill's Bill - still think its a sexy setup you got there. :)

HAHAHA! that's a crack up bill, poor jimmy. :D Yes i think you might be right Bill, i think that might have to be the route the intercooler has to go, as i can't come up with any other sensible path!! btw, holy hell your cooler is big :D i don't think i'd go for anything quite as big, well, i don't really have a turbo quite as big either. I do like the idea of keeping my skinny little rods where they're suppose to stay! :)

Something a bit more interesting today... Choosing the turbo to use. Ummm... It was a toss up where to mount the turbo, either high mount, low mount or side mount (on top of gearbox), and this is what we came up with, after test fitting in the bay it still offered plenty of clearance. The jig was made ready for the runners to be positioned The runners used are thick wall steam pipes, and here are the most tricky bits positioned, the collector and runner positioned

And even that is too much ..... a few blokes & a kebab shop ........ is all thats needed ...... :toast: Kebab performance FTW !!!!! Comeback of the year! TRIPPER, This might help answer some of your questions: http://au.toyotaownersclub.com/forums/inde...showtopic=15425 :) If that's a bit too much for you at absorb in one go, i shall answer your questions for you individually. 1. Are you going to be running an aftermarket ECU? If so, which one? Already running a Apexi Power-FC, and have a Adaptronic and Vi-Pec lined up. 2. How big was the standard throttle body? Standard 1zz-fe throttle bodies are 52mm inner dia, excluding DBW TB 3. How big is your new throttle body going to be? Not going to be. Already is 60mm inner dia, 70 at opening 4. I know your not jumping to conclusions or anything, but how much power & torque are you planning to push out of this inlet? Power and torque would depend on which source for force induction will be applied as the project is not an NA project (as the short runners on the intake manifold would suggest) 5. Will you have supporting bolt on's for this car? Mate, noobs go for 'supporting bolt on'. As far as i'm concerned, there's no supporting bolt on available on the market for my project, all require modification or fabrication. Best come back of the year?? i'm not so sure about that buddy, coz i think i just top the award for comeback of the year! :toast: peace.

Funny you asked that Dave, the ports on the 1zz actually lines up with the 2zz, however the studs are in different locations. As part of the initial research i did, i considered using the 2zz plennum for my spare motor, however why bother when it more fun make one? :) i think with a different flange to suit a 2zz head would be simple! :)

dave, sure! its coming off soon enough and i have all the bits to get it running if you want it! :)
