Hey guys, new to this site, I am in the process of turbocharging my 1ZZ (2001 Corolla) and I thought I would open a thread here to share the progress. I have everything I need en route (exciting - just in time for the snow!), and I plan on developing and tuning this combination over the winter months. The plan is to possibly share my learning curve and reseller savings on to whoever is interested next spring. I would like to get a dialogue going but here is the basic stat sheet:

Based on what I am spending the complete deal should be priced around $1340, I can't give up all my info, but this is not this cheap because it is a bunch of Chinese junky parts! I spent a bit of time coming up with the most efficient set-up possible (with regards to the wallet and the fun pedal :clap: ).

FUEL (good to 340+bhp)
1zz-fe factory fuel system unmolested
supplementary (additional) injector controller
1000cc additional injector, all lines, fittings, bung, and brackets
195 fuel pump
*Possibility of using a supplemental fuel cell so premium gas is used only when under boost

TURBO
all exhaust pieces, fittings, hardware to connect
turbocharger (exact unit not to be disclosed yet)
all oil fittings and accessories
intake and clever filter solution
2.0" charge pipes with premium silicone couplers & clamps

I am going to try to get this on my personal vehicle very soon. I will keep everyone posted as parts come in and work is done on the vehicle. Feel free to e-mail me @ JoeKneale@Gmail.com, my name is Joe, Thanks!

Injectors dont tell the whole truth... You can play around with injectors with pressure and injection time.

First of all the stock fuel system will be a bottleneck, you want a FPR that refrences from boost, IIRC the stock 1ZZ-FE system doesnt have a return line.
Using an additonal fuel cell with premium doesnt help.
That 195 fuel pump is probably gonna come off short, get aleast a 255 HP walbro/MSD, those are what most use. Better to have a pump thats overkill, than something that will end up short in a critical moment.

Sorry for the confusion - it is a single 1000cc injector in addition to the factory 260's, equal to putting in a set of 450s. It is much cheaper to run one big single than a set of four of the "narrow" injectors that monkeywrench racing or power enterprise sell. I know I may get some flak for going the extra injector route but I figure if it is good enough for the TRD supercharger @ 7.5lbs and offer a warranty it is good enough for me (granted a twin screw has different properties with regards to atomization than a turbo, but thats why I am testing this whole deal out with an egt, and individual 02 probes before i think about installing it on someone elses car - if its necessary it will still be cheaper for me to install a set of four extra bosch style injectors in the runners, probably 30#lb units). As for the 340+bhp, that is what the fuel system should support but this is going into a stock motor at around 7lbs so I figure I have waaaaaaaaaay more fuel than I need until i build the motor and turn up the boost. I did this on purpose to give it a one size fits all fuel solution that wont have to be retuned. The reason for the smaller than traditional charge pipes is because there is going to be a good bit of piping and at 7.5lbs it is more important to me to minimize pressure loss and have good bottom end torque than try to provide enough charge pipe for a wicked upper end that just isnt there at this boost level, or natural to a motor with smaller sized factory intake and exhaust ports, valves, and runners. Sorry about the confusing layout of the first post, i was going to edit but decided what the heck.

ok. so an additional 1000cc injector is good for 7.5 psi. but 7.5 psi wont even break 200 horsepower with a 1zzfe. in my opinion theres no way you will produce even 250 horsepower with what you have listed so far. a stock sti or evo doesnt even put out 340 hp and there boosting like 12-18 pounds stock. and those engines are built for "racing"

I know from my experience with DSMs that 18psi can make 400 brake horsepower if you do it right, however It is a fact that even 250 bhp would destroy a stock 1zz pretty quickly. The head on the 1zz has some narrow ports and small valves, but before we start talking about making 400 horsepower in a corolla lets remember that it is a corolla. I inherited my car, but later found out it is worth about $6,000. It doesn't make sense to dump $2,500 on motor work, $1,500 building the transmission, $1,500 on heads, $1,000 on rubber and suspension mods to be able to hold 300 power let alone what a traditional turbo kits can cost ($2,800+). Why spend $8,000 on a car worth $6k? You can have alot of fun with 200hp/200ft lbs trq, and for my money the extra horsepower after that point isnt worth the extra coin or the loss in practicality (the main reason to drive a corolla). I plan on spending less than $1,500 for all the mods I do to the car, my goal is to run a solid 14. I think sometimes people get dichotomic thinking when it comes to making power or boost, either go all out or give up and run 17's, I guess i'd like to find some grey area - if the price is right ;) (if you are interested in the big budget capabilities of the 1zz check out the monkeywrench racing site).

Yes, they also have alot lower compression, which does make things a bit harder on the toyota side. However if you see the honda crowd, then you'll notice if you can provide enough fueling you can have high compression and high boost.

Port size and valve size dont have anything to do with the engine getting destroyed, maybe I misunderstood that part of the post. ALSO 250hp wont destroy anything if you know what you're doing. I'm planning on getting about that much at some point from my 4A-F(TE).

I bought my car for 2500 and spent ~7k on the mods and other stuff and some servicing.

ive heard that you can run high compression with boost and you dont need as much boost to reach lets say 200 hp. whereas if you had lower compression pistons you would have to push more boost and possibly lose throttle response. idk maybe thats a myth.

im a dreamer. but also a realist. and since you say your on a budget my realist side is kicking in and saying you wont hit 200 with "$1340" very safely.

prove me wrong though man.

what kind of turbo are you going to be using?

if a turbo is matched to a motor correctly turbo lag is not a problem, you just have to find the turbocharger that is volumetrically efficient enough at high and low rpms in comparison to your motor

slowrolla37, he said he was making a fuel system capable of suporting thatkind of power

a 195 pump at 7psi with a 1.8L toyota motor should be enough i would think, the 255 pump may be overkill, and since this is a budget setup, with no intentions to make power beyond what this setup will put out once done, it should be sufficient, but then again i don't think there is a big price difference, i haven't checked on the price of the walboro pumps in a few years so im not up and coming with my information

i wish you luck with your project and cant wait to see results.
But if I were you i'd get a 2rz out of a 95-04 taco and throw it in a RWD car and turbo that sucker.. haha. My buddy is running 15 PSI on STOCK internals(hg and all)
:p

that would be an unrealistic goal to have

the fuel system he described probably isnt good to 340hp, wheel or crank HP, im not sure how much that system could take power wise, but i wouldnt put my money on it be able to suport 340hp

what ever the case, i thought he just said he wanted a fuel system a little excessive for his power level he will obtain, not that he wanted 340hp?

I am getting a bad rap! First of all gang the fuel comment I made was saying that the stock injectors plus a single 1000cc supplementary injector was enough gas to support 340 horsepower (not that using this fuel system would make 340, merely it could handle it without topping out - I probably could have said that better and I apologize). I talked to Matt at MonkeyWrench Racing and he said that 15psi could make 325horsepower but like some of you are saying, not on a stock motor, and probably not at the wheels. Secondly there is very little room between the block and the firewall, but you could probably squeeze something in if you used a log style exhaust manifold that exited to the side. That being said I was definately planning on putting the turbo out of the engine bay. I have to be careful here though because the STS (yes the link posted above) kits do this and the tailpipe or remote mount setup is patented. You should notice however that the STS custom kit is around $4000 and does not include a fuel solution at all. At this point in time I am also talking to SCE about an extra thick head gasket to take out some of the compression (cheaper and easier than pistons and just fine up to about 240hp). I just got my fuel computer today and I am throwing this thing together bit by bit. I will keep everyone posted.

Hey Gang, Turns out I am not feeling real comfortable selling a complete kit that is a tailpipe mount. That being said I am still going to bundle the cheapest most affordable fuel solution for a turbo 1zz you can get your hands on. I am also going to install my personal turbo system to mimic the STS style and record the whole process. If there is enough desire I may sell all the exhaust fittings to mount a generic turbo to the tailpipe so you can install your own. I am going to do a writeup using an inexpensive junkyard t3 turbo ($150) to keep the price down and to make it really easy to replicate. Expect the complete fuel setup including pretuned computer for this application, injector, pump, and all fittings to be priced around $530.

hey joe, i worded my comment on your fuel system wrong, i was trying to say that you meant the motor wasnt going to output that kinda power but rather your fuel system was rated to it
 
#29 ·
p.s., joe, i think if you put the turbo right after the downward bend of the exhaus system, you would have enough room to mout a t3

i still think a t3 could be fitted right between the block and the firewall, ive seen setups tighter then the room allowed on the corollas happen

t25s arent as small as youd think, in there defense
