    I think that is just a TVIS filter, I should have some spares lying around.

    The MR2 manual arrived - it's in pdf (35MB) and only covers the 5S and gen2 GTE motors. No mention of the gen2 GE so it must be an American BGB?
    Also got my hands on the gen3 GTE BGB at 30MB, it also covers the late 4A-FE so this must also be American?
    I have another BGB pdf which covers the gen3 GE and FE motors, also around 30MB in size

    Anyone got a link to the gen2 GE bgb? or suggest somewhere I can upload these for all to use.

    Not liking the gasket, check to see if there are places where the water will be trapped, I normally also cross-drill all those water jackets to promote flow and even out the temps across the head

    I also drill at 45deg down between the two chambers on the exhaust side sothat the holes join under the webs. I don't think cutting the webs away is good as they are there to prevent cracking.

    Removing the sharp ledge and the shroud around the valves, best done with the valves out,

    Later heads have chamfers around the valves for better flow but still didn't address the ledge.

    503 race head is my inspiration

    Did you replace the valve seals? Time to do it or face much smoking in the near future

    Why we use lots of antifreeze

    I have put the motor altogether today all went well until I had to do the timing twice just because I forgot the backing plate removed everything now all good will be putting the motor back in tomorrow then see if it will start with-out any problem's.
    For the shims Kevin it's all ok they measure right Bearings also fine motor was fairly new inside.
    The head gasket was ok I drilled in extra holes for the water ports intake gasket I had it made by gasket man make's any gasket I want even told me he could of had made me a copper head gasket just was told to late.

    Me again got to do everything today until I started her up very quick she started problem's was missing at low rev's would not idle rev's up very quick with no problems started smelling heavy fuel found injector's leaked like hell changed that with the mr2 one's modified the plug's all ok start's first kick again no idle and missing at low rev's
    checked for spark everything is fine even tried to advance timing still did nothing now what should I be looking for cam timing maybe wrong because I could not advance the timing much it's like right at the end or do need to reset the computer box pls help she's very alive at high rev's sound's like she is going to be very fast too.

    I have those manuals - no mention of the gen2 3S-GE so they couldn't have got them in USA.
    Need to find some UK or JDM bgb's

    Check the injectors for air leaks, manifold air leaks and re-check the cam timing at 0deg.
    10deg advance on mine is the distributor almost all the way forward. Is the cold start injector firing?
    Does she idle when warm?

    To reset the ECU, just disconnect the battery or EFI fuse for 30min

    Yes I also have the manual's but from the US as well will keep on looking for them in JDM it's really hard to find.
    to check for air leak's do I just pour water over the intake manifold and check how would I know if cold start is firing she's starts first time and we in winter car standing outside.She don't idle at all when cold and when warm I will try and see If I reset the ECU then try the timing again my problem is she is missing bad only rev's well from 4000rpm up with no miss I am thinking maybe timing on the cam's are wrong due to the cam's being cut just suggesting maybe will take the cam's out and replace old one's just to see what will happen.

    Injectors are hard to see, they should all turn freely without binding

    Cams should be on the marks, what are the specs? duration, lift etc

    I don't think you need to reset the ECU

    Kevin they told me the profile was 9.6 and cut at 280 deg but when I measure the inlet with the filler gauge it's fine at 15in 20 ex
    I really don't know now injector's are fine the wiring don't have order in number's on how to connect do they?but should be fine can't really mix them up

    Cams must have been welded?

    Did you mark the injector wires? they can easily get mixed up

    I just put cable ties on the middle 2

    no I did not mark them do you think that could cause to misfire like that but like I said I don't really see how could I mix them up
    wire's are made the right length never know anything is possible with me and if they are turned around it can only be middle one's will change them and see what will happen.

    I still had no luck checked injectors all pipe's changed injector wire's removed one by one all working reason why I now they all fine is if you remove it starts to backfire
    but did not get time to check timing on the cam's that's all I can think of now any further advice will help thanks

    Did timing today it all looked right to me but tried my luck of going one more mark forward off the centre timing mark turn it car will not start so timing was right have to push back everything again checked my compression on all four pistons it measure's at 40 bar I think that is not the problem as well I am stuck now do not know what to do next help please

    40bar = 580psi???
    Should be around 12-13bar

    Which marks are you using? show us some pics cuz you can move the cams more than 1 tooth and it will run

    i don't want to sound rude but that compression meter is either reading in a different number than BAR, is horribly out calibration, or is flat out rubbish. it does show that compression is even and that's good.
