hey guys i just got my head of my 3k motor ported and mechined the valves liped and new valve stem seals i just put it all back together and it is running like shit i have done the tappet gap and new oil and i still can hear them really bad the timing isnt goin my way either i set the point and did the timing and it is sounding like I'm running on 3 cylinders it is rough as all hell it has heaps of compression? i just don't understand what is wrong and the temperture is geting in the red but it has new thermo stat? can i please have some advice

Do big port and small port 4age heads have the same size inlet valves? If they do, would the air flow be any different between the two heads? Just trying to work out which head/ cam combinations would work best. thanks

Does anyone know what is involved in fixing this problem? The engine is a small port 4age. I’ve only just brought it and apparently there was a problem with the old harmonic balancer key way having too much clearance. The harmonic balancer I have looks alright but I’m a bit concerned about the key on the actual crank. It looks a bit worse for wear. I haven’t got the new balancer on yet as the key would need to be filed down a little I think as it’s hitting the balancer. It looks kind of bent and worn so I’m thinking it would just get worse until it brakes.

Hi guys, Just recently finished the 20v conversion in my AE95 and having some problems. Not being very experienced with this sort of thing I had friends helping me and when it came time to grind the block the alternator was still connected to the motor and got covered in metal filings. I blew it out with the compressor as best I could. The car is together and was running but I have no battery light on the dash. I'm pretty confident the wires were hooked up properly. I took it for a test drive last night and got about 5 minutes down the road before the headlights and dash lights all went really dim and the car cut out and wouldn't start again. Does this…

turns out my bottom pully is really noisy (4k) i thought bearing but a bloke at work swears it doesnt have one just some rubber stuff or something any ideas? oh n water pump shat itself anyone got a new one lying around

Hey guys I'm needing some help figuring out what this mount thingo is, i dunno if its just for the stabiliser bars on either side or whatever. basically i need to know as i need to ditch mine on my ke26 and get some better condition ones as when the dude that owned the car before me made up the engine mounts for the rotary he welded the absolute shit out of those 2 mounts and blew holes n warped em etc n my panel beater can't fix them n would b easier to start fresh, since i need to have my engine mounts relocated anyway. heres what I'm talking about as I'm not great at explaining myself. also if anyone would know where i could track them down, if anyone knows of any ke…

Hey everyone i have a shitty ra40 celica with an 18ru engine 2 litre carby thing anyway i can start it and drive it for a while and then when i turn it off i wont be able to start it again, it will not have spark from the coil for about half an hour and then i can start it. keeping in mind the timing chain is on its way out and ive never checked the timing/points probs something i should do anyway any advice?

Ok so I'm new here and have had a bit of a read of the post's on the KE20's and the diffs. Well the time has come to replace my stock 20 diff. The car is running a Blue Top 4AGE with no modifications. I have been reading that the T series would be ideal only problem is trying to find one. So brings me to the question How good are the S Series diff's and the E series? Also considered putting a 105 series Alfa diff in which would only require the shorting of one side has anyone done this before? Also i assume that it is not possible to put a T series head in a S series housing? Any opinions would be appreciated.

hey i have a problem with my 4age in my 93 rolla idling when the AC is on she idles at about 600-1000 when ac is on and is unstable, she doesnt just sit on 1k or 600 she moves all over the place!!!! does any one know how i can fix this? my 4age uses too much fuel she goes through pretty much a full tank in little over 150ks and i have only a pod in the car, can anyone help on this?

Hi, I have just got a 1600 2t out of a celica for free and i currently have a 4-ac with a t50 box, i know that the 2t comes stock with a t52 but i wanted to know if a 2t could go in to a t50. Also i was wondering is it worth it, replacing a 4-ac with a 2t. I believe that the 4ac puts out about 90hp (may be less as is the aus version and haven't taken the pollution gear off yet) and i think the 2t puts out about 100hp (not so sure about that)

hey guys as i have recently got a locker in my ke70 as i have been sliding the engine is dying off and loosing all its power as soon as the car kicks out and starts sliding. i have changed the dizzy leads and coil pack as this still didnt work i took dizzy apart and sleaned all the points etc. could this dizzy be rooted aswell? has anyone had this problem before and if so how did u fix it? thanks

O.k to start this is a 16 valve 4AGE in an 87 model AE82 hatchback. Anyone know if there's a simple reason why my motor is blowing smoke seems to mainly be grey ? The car has plenty of power actually goes real well. Only thing is it does idle inconsistently it jumps up and down. Also the tappet cover gaskets are leaking but i wouldnt think that was the cause as it mainly seems to be burning off at the extractors. Any help or suggestions greatly appreciated.

Hey all rollaclubers. Wanting to change ignition coils, so I'm trying to find out the standard specs on a standard k series points type coil. Ive been looking at the MSD blaster 2. But theres no point going and buying one of those if its not much better than the standard coil. So if anyones got the specs or know where i could find them please tell me, I have looked everywhere for them. Cheers Corey

Hey I have come to a brick wall in my conversion everything is kicking and ready to go just need the timing done. I have set it to TDC (top dead center) and played with the dizzy but all i get is back fires. Ill pay someone to come out this weekend and time it for me and get my bloody car going. I'm in Brisbane on the south side in Tingalpa. Contact me on 0425617228 Ian

I was poking around the wrecking yard today and came across a 87 or so toyota van with a 3y engine. What shocked me was it looked an awful lot like my 3k..... are they related or am I just imagining this. if these are related I'm thinking swap mmmmmmm 2 litres........

G'Day all, I'm currently in the market for some performace extractors to fit a 4A-C motor (see WTB forum), but, before i go ahead and spend hundreds on getting them custom made, I would like an idea of what the potential power increase will be. I'm asking those of you who have done this, or know the effects of this to give feedback on what the benifits will be, and whether or not you believe it is worth getting the parts. Thanks.

Ok people, i just had an idea. So i don't get mixed up, and for other newbies as well, could we post here ure name - and ure car and ure rolla clbu name Eg. Teddy - Rolla name / Nick name Matthew - Real Name White 1983 Ke70. Stock Etc Thanks, and hopefully if we get all the regulars here, soon every 1 will kno every 1 that much better! Cyas Teddy

hi I have a 7 rib block but it has no oil return pipe, The other 7rib I have has it and also oil squirters. Can I still use a smallport head on the block with no oil return pipe??

Hi All, I know this has prob been covered but I don't have time to search as I am at work. when painting a ke30 I know it will be about 4 litres of paint required but how many litres are colour and how many clear??

I would like to change the stud pattern on the rear of my ke10 to 114.3. Wondering if I could use a bench drill and an accurate ruler or vernier calipers to measure 4x 114.3 and re-drill the axles and fit new studs? I have a spare set I can practice on but is this a big no no for any particular reason? I realize the rim has to sit perfectly flush on the hub so accuracy of the stud holes position and straightness of the studs is of the upmost importance.

hey does anyone kno much about rt104 corona's, having some troubles looking for parts and upgrades if anyone has some info on what brake upgrades i can chuck on feel free to let me know please

As the tittle says i need help and i did search thruout forum BUT may have been searching for the wrong thing. Changing globes in ke70? mainly park light and reverse light do i need to take complete light out meaning tail light and headlights or can i just do 1 at a time? thanks and yes i know I'm sorry coz I'm gunna get in trouble for looking up the wrong thing

as stated in theory this should work aye pedal box supposed pushrod end! were supposed push rod end will bolt up so theoretically this should work if i drill a hole around this^^^ area and space out the said pushrod part to clear the brake booster???

just snapped my clutch cable on 4k 4 speed but only the end bit that goes on the clutch pedal anyone done a quick fix or a cheap good cable i can nab???

Hi, Ive been reading up that 32/36 DGV weber are a good upgrade for k series motors. I'm trying to work out what cars these come of so i can get one from the wreckers and get it rejetted etc. I think XE-F falcons have them, but they have a 3.3l which is considerably bigger than my 5K. I just wanted to make sure that they are ok and if they can be jetted down enough to suit my motor. Also if anyone has done this conversion their advice would be helpful as ive searched the forums and not found much. Cheers

iv got a rt104 corona with a s14 running gear, need some advice as to what brake upgrade id need.

ok so i recently purchased a 94 csi hatchback for dirt cheap and i knew it had engine problems i took it to a family friend who is a mechanic and we thought we found the problem put in thermostat new head gasket new hoses new water pump and i still have the same problem whenever i take it for a little bit of a thrash it overheats on me does anyone know what could be the problem? is it the engine? it's only done 160,000km as well no matter what i seem to do it just goes back to the same thing would an engine swap solve this? if so what is recommended if someone could help me out it would be appreciated thanks

Will a better carb and exhaust wake this engine up or should I go ahead and sell the car to find something with a more tunable engine? I have a Datsun 1600 carb to install and a 2" exhaust is in the works. I want to know if I'm wasting my time...

Hi there, I have 90% done my 4age in ke70 conversion :) now as for the exhaust, I have got a quote to do a whole exhaust system custom made for it ($1100). But i am broke, do I have any other option, can I get exhaust headers for an ae86 corolla and weld them up to either the original system or a slightly better one. will the ae86 corolla exhaust headers work in a KE70. Thanks for your help in advance !

Hey I just bought an AE71 yesterday and was wondering if there is anyone who knows about upgrades for the 4A-C. I'm only 16 and don't have the money for a 4AGE yet but I would like a little more power as I would like to drift.

The fuel pump on my 4k motor was just drizziling fuel but now pissing out everywhere i havnt had a chance to have a close look what the problem is but i went to repco to get a new one and was VERY surprised at the $160 price tag which is $160 more than i paid for the whole car just wondered if there was a more updated pump sytem available and how simple is it to chuck in???

hi guys, i was just wondering to put a 4A engine into a KE70, can you use an AE86 crossmember or does it have to be an AE71 one? i can seem to find any information on the AE86 crossmember, only stuff on the AE71. any help will be appreciated, cheers hendo.

Can anyone shed some light on my situation. I've got an AE112 corolla sportivo and i've just been told the bearings in the gearbox are shot. I think it's probably a lot cheaper to put a new gearbox on than repair this one. Can anyone confirm the gearbox from any 7A-FE will fit another, say from an AE96 or AE101. I can find a gearbox fairly cheaply from an older model corolla with the same engine, i just wanted to make sure the gearboxes are compatible. Cheers. Andrew

Hiya, I've got a KE70 with a 4k, I'm gonna change the oil. How many litres of oil goes in there? :wink Thanks.

I have the standard k series radiator in my car with the 2tg and as the picture below shows the hose doesn't have the bend to fit on. As I see it I have 2 options 1. find a hose with that 90 degree bend in it - any ideas on that one? 2. Get a piece of metal pipe to fit between the hose I have and another hose that is a 90 degree bend... Any help on this?

Just wanting some info on where to find rims to fit my KE30 I'm after these type of chaser rims below, 15 inch to suit the 114.3 PCD What models cars had them? And where would be the best place to look, or does anyone have any they want to get rid of? Thanks

Hi Guys, I'm new to the Rolla site as I have only just got 1. I have just brought a GP turbo and i having problems with it. The car has the following info.

hey guys I'm looking to buy a 4age but not sure if big port or small port it is out of a late ae92 with silver cam covers and black writing please help so i can choose thanks michael

as stated above does anybody know the pcd of a ta22??

Hi, I have a AE92 and I'm doing a engine conversion to the 100kw 4age. Now I have the engine almost ready to go in but i need those inner cv joint cups off the old gearbox. Does anyone know how to get em off? I ahve it down to the bare tranny. Thanks Ian
