Hi, Ok after some searching I found nothing that can give me rock solid help with my head problem but I found the old rolla site that had the numbers that were found cast in heads on corollas so you could match your heads up. Out of 4 of my rolla heads I had 1 of them match up :) The number on the heads I have were: 8 - this is off a 4K-E 83 - ?? 6 - Off my running 4K out of a KE70 31 - Off my running KE30 3K-C motor So I was wondering can anyone tell me for sure what type of head my 83 one is and if my KE30 31 head is a big port mild or small or normal? So I though in this thread I would like to compile peoples head numbers with the type of motor it is if it is standard. As if people start quoting a 3K head number on a 4K it will screw it up a bit. So feel free to start posting numbers and engine type. I have started a few and also used the ones off the rolla site to get the ball rolling. I have also added my heads to the list one in the unknown and others there they belong. Cameron P.S. The number is between spark plugs 3 and 4 on the back of the head. Engine - Head cast number. K: Mildport K: 45 3k: Standard 3K: 5, 19, 31, 85, 86 (pending) Smallport 3K: 25 3K Bigport without water jackets: 24010-190, 24010-141, 24010-200, 24010-217, 24010-195, 24010-155 3K-H: 33. 4K: Standard 4K: 3, 10, 57, 20, 13, 2 (but with no ridges under spark 1 and 4), 6, 65, 1 Mildport 4K: 11 4K-E: 8 5K: 5K: 24, 2 (this is with the ridges under spark plug 1 and 4 so it is a dished piston head) 7K:

ah sweet ill have another look..lol So many threads now. As I have 2 heads by eye same thickness but one has a slight different shape to it as it is narrower so ill look and play around with them I think. Cameron

OK as a note this project wont be anywhere near a car. If you read the manual for the car pollution gear it says this part is designed to deliver compressed air into the exhaust. So in turn these are like a super charger deliver compressed air. So a friend of mine did this once he got one off a holden and strapped it to a lawn mower and magic he had a supercharged lawn mower. No joke worked flowed a good amount of air easy for the mower and an old spring and valve set up we even had a blow off valve for it..lol But after this it was move off a lawn muncher so does make more power so I was thinking a super charger for my pocket rocket motor bike :) As the one he had on his mower was a holden V8 one so it could push more air than one off a Toyota 4 banger. But a pocket rocket with this off a Toyota should be mean :D Cameron

Hi, Just going through a KE70 pollution manual I have and it talks about a air injection (AI) system. These push cool air into your exhaust under pressure and helps promote the oxidization of CO and HC in the exhaust. So I was wondering if anyone has one of these they can take photos off or if in the ipswich area has one for give away? As I am interested for a possible power increasing project not a decreasing one like most pollution gear is..lol Cameron P.S. it was on the 3T-C, 1X corona motor, or the celica 21R-C motor and the 5M-E crown motor.

Hi, Ok if you want to be able to tell the difference in your K series motor head scroll down and add or look for your number in my list so you can see what type of head you have. Also anyone know where the 83 number head is from? I think it is a 4K one? Cameorn

Yes jets run on thrust same as rockets so you can't really compare them well. But if you were to hook up a axle to a JET main shaft it would make a shit load more power depending on the size of GT. My small jet engine I have at home has a intake of 97mm and creates 80HP on the power take off shaft (one used to drive the wheels) and on the main engine shaft it uses over 200HP to drive the comprressor at full bore so my small ass GT which chews 78 Litres of air a second makes nearly 300HP and mine in the jet world is considered a micro turbine cause of its size so a full scale jet shaft driving a car would give a top fuel drag car a run for its money in power ratings but the top fuel might just still get it down the strip as jets do need to spool up etc. cameron

Hey thanks for that information. Coating the pistons might not be expensive for me as I can get stuff dipped from chrom to teflon at avation standards for a few beers..lol So Ill look into it. But with boring the cyclinders to each piston not a bad idea but the pistons when meassured were all the same at the top and on the skirt were shrunk one was less than 1 thou other was 2 thou rest were in between these two. And it was jsut the skirt of the piston so at high RPM I can see the 2 thou one failing first but I don't plan to push hard so it might be best to bore to suit then just install.. Thanks Cameorn

* Under full throttle, a Top Fuel dragster engine consumes 11/2 gallons of nitro methane per second; a fully loaded 747 consumes jet fuel at the same rate with 25% less energy being produced. I always find this quote hard to belive but here goes my view..lol How much power does the 747's Pratt & Whitney engine produce? Well a Boeing 747-200 cruising at Mach 0.9 at 40,000 ft (12,190 m). The aircraft's engines produce 55,145 lb (245,295 N) of thrust, only a quarter of its rated static thrust, to cruise at a velocity of 871 ft/s (265 m/s). So using some basic equations we calculate the power generated by the 747 to be 87,325 hp (65,100 kW). And I belive a top fuel dragster can't make 87,325 shaft HP off the line..lol Cameron

yes I do know going through a yellow light is illegal if you can stop but some times well you probably could stop but just to save braking hard just power on through. But I never power through when I need to turn at lights only straigh ahead as turning becomes to dangerous and can't do it as fast. Cameron

COMMIT PEOPLE... if I'm coming up to lights and to fast I say 3 second rule before other lights change and commit. Pump the right foot and go and sucks as all the insurance places say u hit them so u pay. SUCKS. This happened to a friend of mine had the nicest WB holden ute V8 all done up yada yada. So a little old lady was driving on high way and just after a merge where my friend got on she decided to all of a sudden apply her brakes hard and my friend just merged onto the highway and since he was speeding up quickly couldn't stop after he slipped in behind her and he in turn hit her then a semi truck couldn't stop and went into him writing off the car. His ute since he runs his own business was full of tools so it had about a tonne of weight in it and it also wrote her car off but it put him out of business for a while while he had to get another ute. Lucky he was ok but the ute was about the length of a Mazda 121 bubble after it was all over. Similar thing happened to me but I was reversed into and didn't have to pay so I got a KE55 bonnet on my car now. So one good thing came from my crash. But it was crap not having a car for a while to get around. Cameron

Hi, Tacho is it after market in box with instructions? If so follow them. But if not tachos run a wire to the ignition coil and then they are just a simple frequency counter that counts the pulsing coil and then gives you a rev reading so just wire it to your coil. EASY. My corolla has a lot of lose ends in wire as I believe it was one loom for all so the loose ends were where stuff is meant to go but my car never received those parts from factory. But in my KE70 when I looked behind the dash I could never see wires for a tacho behind my clock. But the wires you found if you know they are the tacho wires from say a car manual and are lose just look at the diagram in your manual and it should have the colour of the wire and where it went on the tacho. But my bet is red is for tacho power...lol But pop your bonnet look at the wires on your ignition coil if one is green or brown and goes back to the fire wall it will be the signal wire and the 3rd one left will be the earth/negative. easy Cameron

Hi, Jip where abouts is this kelly wrecker? Sounds interesting. Also do you know if thye have any of those under the glove box trays for a KE30? also they have many good KE30 bits to grab? But at the wreckers once I saw they had a stage one fan off a TF-30 jet engine used in the F-111. And well I just wonder how they got it as mmmm people arent meant to have them..lol Cameron

Anyone from here actaully going to it? Ill be there got 10 tickets as i got all my freinds to kill their livers and I got the labels. I'm on thge floor in GA non-seating so ill be there... Bands are OK but last year they just filled us with crappy adds during the show so mm it not that great. So I need to get a hold of a pepsi t-shirt just to shit them off there. Anyone ever seen a pepsi t-shirt lately in abrissy shop?? cameron

I get people look at my KE30 when ever I park it as work as all the light from the menu board reflect the light into my head lights so I get all these people looking at it and seeing if my lights are on..lol But the other night I had a few people packed into a KE20 bright orange staring at my car for ages when I was leaving. was that anyone here? Oh by the way I'm at dominos pizza near willowbank? Cameron

Hi, don't know how hard my 3K has rev trev as I have no tacho. But too quick you said ur tacho is done bodgerly if it is on the coil and held firm with no other wires crossed can't see why even if it looked messy isnt readign the right RPM unless gauge is out or shit it's self..lol Cameron

Yes I run 110PSI through my turbo but I have since dropped it back to about 90-100 for faster spool up. But lets just say my turbo isnt in a car..lol And I was always told by turbo shops for every PSI of boost run 2PSI of oil pressure so for 30PSI turbo pressure run 60PSI oil pressure and I run 35PSI+ at high temps and a lot hotter I also need added oil for cooling. As in a turbo bearing the oil does funny things and in all the twists and tuns yes can increase pressure as I have a report laying around on it some where.lol Cameorn

Yeah I think your right it is a return line maybe as it does come out near where the fuel goes in. And I think previous owner blocked it to well give 4K a crap load of fuel. Cameron

Hi, Got a photo of the webber now. It is a down draft so will bolt on to standard manifold. But when installing on my car might sound silly but can i hook a KE30 polution system into a webber? I know i can on carbon canister and the vac line to dissy butis that it? Also below is a pic of the webber with a line plug can anyone tell me where this line goes? Cameron

Hi, Just been cleaning up my 4K slowly still getting ready to put it into my KE30 and I noticed the top radiator hose mount on the motor is different. On my KE30 3K motor it has a switch on the housing with two lines running to it that are vacuum lines. And one goes to the carby and other to the dissy. Then next to it is a taped hole that is blocked off right now with a plug. See photo below. On the 4K I have from a KE70 on it's housing it has just one hole and in it is like a temp switch of some sort and nothing else. But on the other side it has the temp prob for the water temp same as the 3K in the KE30 so I know this switch on the top is not for temp but what? See photo below to compare it? So just wondering does anyone know what the switch in the 3K does with the vacuum lines and the switch in the 4K? Also when doing the engine change to save rewiring I'm using my old alternator and other parts so should it be advisable to use the thermostat housing from the 3K on the 4K? Cameron

Ok well for added power to the 4K I'm getting better parts for it slowly on a tight as budget so I'm planing to get extractors etc soon. So any difference is better than none. The webber tell you the truth I havent seen it was in the car other day and he said it was for sale and car was going with it on. He said soon as he fits his 4age into the KE70 I can have it so I know it works but havent seen it. But I'm going to have a closer look at it tomorrow so I can post pics and info then. cameron

BTW, If you run cam webber and no extractors I am pretty sure the exhaust can't get out so puts to much back pressure on the motor and forces clean air fuel oout the top of carby and in worse case car wont run. Simple answer cam will let more air in so u need to get it out faster than before and stock exhaust well it is a big small to shift any extra air. Cameron

Hi, Well the webber I picked up came off a wrecked KE70 so I grabbed manifold,webber and adaptor plate and lines. So Hoping it will bolt into my KE30. But I wannaa keep the polution gerar as on a KE30 all it really is is the carbon canisster to get fuel fuems back to tank and the oil fume line back into the inlet. Ill see what I can do in the way of rigging it up. As I have to use car for a daily driver but want more omph from the 4K so got the webber. So want to keep polution gear on it just so if were ever pulled over it is there to say. Cameron

Hi, Ok so I can install the carby with no extractors good. With the adaptor plate I talked to the guy this morning and it comes with one so that should be no worries. Now for the polution system does it go into the carby at all in the KE30? And can't the webbers take a polution system as they were pre 19XX so they never needed it? Cameron

Hi, Just wanting to know if you run a webber on a 4K motor that is bog stock will I need to also run a set of extractors? Also what will it take to fit the webber? Is it as simple as an adaptor plate? I was looking around at photos here but it seems there are a few types of webbers so what parts are needed for what type of webber? And last of all I am planing to put this 4K inot a KE30 rolla. After I install the webber will the pollution gear fit back on or how should I go about running the carbon canister etc? And if I can use the polution gear is it lefal to run a webber with out it in a KE30? Cameron

Hi, With those turbo fittings some one wanted info about turbos in a certain rage will have the same bearing housing size so the oil fittings and snail shell housings will fit it. So all you need to do is go to a turbo shop as for an oil fitting off any turbo with that size bearing housing. As turbos come with a bearing housing up to a certain compressor size when the comp gets to big for thrust bearing to handle they go to larger bearing housing with bigger bearing then repeat. For a turbo I have with a small 3 inch compressor inlet diameter I have the mid sized compressor for my bearing housing so I use a few different parts on mine eg oil drain as on some applications the oil drain for my housing had a few neat tight bends it in and saved me bending it to fit the oil lines. So I bough it and not the original to fit. Also for the oil inlet my turbo had a BSP thread so go to ur local nuts and bolts and get a 1$ fitting to fit. I do this run 110PSI turbo oil pressure no leaks and a LOT cheaper than the fitting from mack or someone..lol cameron
