550cc
ok so i am upgrading to 550cc injectors, and i was wondering if i needed anything else, like
lexus AFM? adj. fuel pressure reg? fuel pump? |
at the least you need the AFM
|
k well i'm orderin a new lexus afm, thanks. now will this knock my fuel cut up to about 15lbs of boost
|
i just ordered a apexi S-AFC also
|
if i'm not mistaken i read on one of the supra forums that lexus afm and 550's raise fuel cut to 18 psi.
|
all you need is the injectors and the afm. though they say you can go to 18 psi i dont recommend going any higher then 12. beginning of the summer i did the same thing raised it to 15 psi with my boost controller and now im having turbo trouble. so unless you plan on getting another turbo dont go much higher then 12

lol
uh sorry to mention this but this is all going on my rebuild im doing, currently my motor isnt even in the car specs: block : resurfaced : hot tanked : pressure tested ok new oil pump drive bearings stock pistons : forged : heat treated tops : .20 over stock rods : pulled out and grabed all the best ones new bearings new rings all bolts and studs are ARP new HKS HG : ARP studs new Water pump new oil pump all new gaskets TRD oil filter thermostat and gasket fidanza Flywheel stage 3 XTD 6 puck clutch and pressure plate Head : resurfaced and also EGR cooler plate: Port and polished : hot tanked stage 1 cams stainless steel headers with wastegate dump pipe fidanza adjustable cam gears stock valve : springs : retainers Garret T70 Gt46 : Compressor Wheel - .66 A/R, 48.9 trim Turbine Wheel - 1.05 A/R, 61.9 trim 4.25" inlet, 3.38" outlet T4 flange with V-band 50mm wastegate Magnicore kv-85 8.5 spark plug wires NGK IRIDIUM XI RC 550cc injectors /w clips lexus AFM Cooleze Turbo inlet 3 inch intercooler pipeing silicone couplers hose tecniques hose kit EGR block off plates custom 3 inch exhaust : no catalizers : new 02 sensor bunge : v-band Apexi S-AFC 2 cheap oil filters 15 Q. 10/30 oil coolant P/s fluid lots of brake cleaner lots of electrical wire in many colors : 16G and a windsheild wiper :) grant steering wheel and hub and quick release there is probably more that is about my list of everything i have either already ordered and are waiting on and things that are all done. i'm taking pictures of the rebuild so far and the old motor is out and the new one is being put in probably by next weekend hopefully. all of the random shit under the hood will be relocated like battery/ignighter/relay box/ect... all harnesses and connectors are being replaced all i want to see when i pop the hood is engine and turbo :) the turbo has a max peak of 35psi and can handle up to 1000 hp. i'll admit its a tad big and may have some clearance issues but as for the wastegate also, i'll make it work. i'm doing this rebuild because of a BHG gone beyond bad. cylinders 6,5 and 3 were blown, bearings where showing signs of being ran low on oil and running really hot, head was cracked and multible oil leaks and the sweet coolant leaks. but the new goal is building this for a car show sponsered by my college, in the spring time. so far the total price for everything listed above $2,358.45 now what do you think i can handle for boost :O and what do you think i will be able to handle power wise |
|
well see my limit is 2,700. plus again, the pistons are forged and heat treated tops, so they will be better than stock "stronger" and also they are bored .020 over. same as with the rods.
|
now has anyone used the turbo headers? the ebay ones? because i have one and i was wondering how much clearance i will have for the wastegate and also my rediculous turbo :P
and also with the apexi S-AFC II gen during the break in process should i just run a 0% +/- then once it has been broken in should i go ahead and tune when i can boost? how much power do you think i will have with all of these items and also 18psi? and does anyone know where the EGR block off plates go? i know that i have the 2 intake block offs not the one that goes onto the EGR cooler exhaust side and the other on the intake. From what i understand there is one that goes on the upper intake then the other goes onto the lower last but not least how long should i break the pooper in for? because i keep getting ranged from 1,000 miles to 10,000 miles, and just for a little more information a tourqe plate wasnt used when boreing it. oh and found some bad news on the stock turbo, not only was the turbo seal bad and squirting oil all over the place, the bearings were done, and also there was a huge crack by the wastegate that went all the way trough, its SICK!!! :P but i guess thats why i got a new turbo |
anything?
also i'm looking for a good manifold for the new turbo, i need one that will allow a T4 turbo and a 50MM external wastegate, i the ebay stainless steel headers but i think there will be some clearance issues, i saw the ones on HP freaks but what would you guys recommend? |

I'm kinda wondering too about the lexus afm and injectors. Right now i'm hitting fuel cut on my shimmed wastegate and 57 trim but i don't know where to go next.

well i have gotten almost everything from ebay guys. alot of other places that will cover injectors, AFM, and adj fuel press reg. will be
Welcome to SupraSport.com ltd - We don't make the car, we make it faster! Performance Parts Aftermarket and Racing eBay - New & used electronics, cars, apparel, collectibles, sporting goods & more at low prices here are some links to those items here is a complete kit includes AFM/INJ/INJ clips this will give you most items, after this you just need the adj. fuel pressure regulator and you'll be set. ADJ. press. reg kit LIPP 1 this allows you to control the amount of fuel entering your fuel rail, it will make it so you are going to be killing your engine with an overflow of fuel and possibly burst your lines. although the walbro pump is very stong and can take alot, i still recommend this adj. pressure kit. if you really want there is another removal system to get rid of your Fuel pulse thingy, i really dont know what that does but its ugly and not needed. and here a link for that kit to. fuel pump 1 2 there are diffrent types of pumps availible, the walbro is the easyist one though, it will go right into your tank just like the stock one. pushes 300% more than your stock. and will allow you to do your 550cc/+ injector system , now dont order the venom injectors, they have been highly known to stick, and this can make a really big issue. so i repeat DONT ORDER VENOM INJECTORS, RC are the best so far. PTE "precision turbo engine" are the next best. i am running the pte 550 and are sweet so far. injectors 1 - supra sport 2 - ebay - 1000cc injectors availible from these guys also these will allow you to use your pump to its full potential, and plus they are almost needed when you upgrade to your Lexus v8 afm, i've heard of people not changing the houseing but just the sensor and running somewhat lean. i dont know this for fact but its just something i have recently heard, DONT ORDER VENOM INJECTORS THEY STICK AND WILL CAUSE MORE PROBLEMS. AFM 1 - supra sport 2 - these are used and imported from jap. but very low mileage and clean and work. for injectors with the lexus afm 550cc are good 680cc are better. but i dont see why you cant go bigger maby even a 750cc like i posted now just to make things even simpler, i will say that i recommend getting a fuel controlling system like the apexi safc "ebay you can find them for like 25$- 100$" all of these items together with forsay the 550cc injectors you should be good up to 450hp-500hp. if it comes down to the point you still are hitting fuel cut then the next item recommended would be getting 1. HKS FCD - fuel cut defender will remove your fuel cut system and if i remember right you should be able to adjust them to were you want your fuel cut to be set. HKS USA Driving Performance - Homepage 2. i should have put this in the list of items because it is very important to watch your Air/fuel ratio when doing anything with your boost and fuel. but recommend any digital system that will use a wideband sensor. not one you tap into your stock 02 sensor. wideband is very accurate warms up faster. and is a real time reading. and very good for tuning may i put. i personally am running a AEM UEGO w/wideband, and so far its pretty sweet, others recommend or use the Powerdex AFX-Air Fuel RatioMonitor now your probably thinking to yourself, damn this is alot of money. but in the end its all worth it. you will get some more horsey's and you will be able to boost up to 18psi "not recommended on your stock ct-26" or 17.99psi so i have been told i'm not sure yet since im still in the process of breaking in my motor :P- - -||____XD hope i helped you all out with your questions. i'm willing to help to what i know so ask again and ill reply back for you |
Great info west side. Thanks a lot.
What is the need for the new AFM? Looks to me like it's just a little larger bore, but we still use the same actual original sensor. Would you expect I would see a benifit with just 550cc injectors? I have the fuel cut defencer on but I think it still cuts at about 12 psi. May not be set up correct. |
i got a question
i checked the replacement afm they said its a copy of the lexus afm which wont come with any of the electronics of the lex afm itself its says you have to reuse the honeycomb and the black box? doesnt the lexus afm has diffrent electronics than the ones that came from the 7mgte? or is it jus the size of the afm that changes? |

mmm like i said the houseing of the AFM is bigger on the lexus version compared to the 7m version. replacing the honey comb? uh i dont know if you can even do that, hell if my honey comb broke i would just go and get another AFM and the black box is the sensor itself, and yes totally different, just has the same connection as the 7m, so its just a plug and play |

The Lexus AFM does NOT come with the black box sensor. It says to use the original 7M-GTE box/sensor. So it appears all we would be buying is the metal AFM housing and transfering the original honeycomb and sensor to it. Maybe the original sensor detects more air thanks to the larger AFM housing, compensates for that in combination with fuel cut defencer allowing more fuel, and the now larger injectors gives more fuel. Result for me I hope is...larger turbo + boost controller + fuel cut defencer + larger injectors + larger AFM housing + HKS intake = more HP. Does this all make sense? |
well the one i got from ebay has the housing, honeycomb, and sensor itself. again i really dont know if the 7m sensor would be picking up more than the lexus thats something that we would have to search for, like specs on the sensors.
|
:gtfo:ya when i ordered my lexus afm it also came with the sensor not just the metal housing:sadwavey:

Fuel Injector Clinic:Toyota Top Feed The injectors listed below are all low impedance/peak&hold top feed injectors so you will have to convert to a top feed fuel rail to run them. This is typically less expensive than purchasing side feed injectors, since those are scarce and expensive. Also, once you have converted to a top feed fuel rail, a lot of other injectors will fit if you upgrade to the next level. We sell a kit with 6 x injectors, a fuel rail, fuel pressure regulator and all the bungs and harness pigtails starting at $710.00. 550cc good for 360 wheel hp or 425 crank hp 650cc good for 425 wheel hp or 500 crank hp 750cc good for 485 wheel hp or 575 crank hp 850cc good for 550 wheel hp or 650 crank hp 950cc good for 620 wheel hp or 725 crank hp 1050cc good for 680 wheel hp or 800 crank hp 1150cc good for 750 wheel hp or 880 crank hp |
yes we have top feed, as for the numbers for hp and crank hp i dont know how accurate that is, maby for those injectors though. again i highly recommend the PTE or RC injectors. they are the best your going to get. as for size i recommend 550cc - 780cc
|
how much hp and torque would adding the 550ccs and the lexus AFM give u?
|
not any clue at all, i saw it as more of a supporting mod for your other motor work.
