    What would be the weight of each motor be around

    - 4agte...

    -Ca8Det...

    -Sr20Det...

    Im leaning towards the 4agte at the moment because of the simplicity of the swap into the 86.... ie: no mods to mounts, gearbox ect... plus I plan to wack the gze in and boost around in that untill I save enough for the snail conversion.... as well I believe it would be better balanced and suited to the sprinter......

    I like the idea of 4agte... Its different to the mirriad of sr's and ca's out there, and I imagine it would be hilarious to see the expressions on peoples faces when they find they had their ass handed to them on a platter by a 1.6.

    I would keep it toyota, but thats just me. Its like putting a 2j in a gtr. The 2j is a great motor but so is the rb26.
    the sr/ca is a great motor but so is the 4ag

    Id assume the 4agte and the CA18det would weigh the same, however the sr20 would be creeping with abit more weight even though it is a alloy block.
    Decoys is definately on the money, however with the nissan aftermarket support and how parts are so common, the CA18/SR20 seems like a much better idea. With the extra power which can be made by the nissan motors why not use that to your advantage, im looking at it from cost to power point of view. However, I will be keeping my motor 4agte now as, I have already got it.

    240rwhp can be made from a standed 4agze engine. i know of a 4agze motor with a skyline turbo running 14psi, mircotech, xf tb and made just over 200rwhp. with a better designed turbo, more boost you could make 240. if you want more all you will really need to do is head work as the bottom end can take a bit and are cheap too replace too. as for putting in a ca or sr you will have to spend more money to change suspension now the front end is heavier, unless your not worried about that, the only advantage i can see for putting a ca or sr in is if you want more torque than the 4a can provide.

    Yeh, damn straight.... cant wait to shame some people with a 1.6.... its not gona smoke all competion but Im sure its gona be quite a lil weapon when conbined with the lightness of the 86, esecially after a lil more weight strippen.

    with a aftermarket ECU a easy 210rwhp can be made, however as the internals are fairly strong in the AGZE. The sr20's can see up to 380rwhp without being cracked open, but most guys will argue that their rods will bend, their pistons will crack, and big ends will dissapear(however cams, cam gears and a mild port will be required). If anyone remembers a dunger of a red stanza that does huge wheel stands at the jamboree last year, and runs 10.40@136 is running a standard, rebuilt red top bottom end, no gas on C16. fairly damn impressive
    The decision is easy when trying to achieve more power as I have worked out the power to weight ratio, a car with sub 1000 wet weight with power of 220-240rwhp should run a easy 12. However, as the AGZE's lack in torque, head work will be definately required.
    In the next few weeks if my car doesnt sell, it will be seeing a rebuild with new bearings, linishing and cyro treat crank and rods.
    I will be running re-ground cams and some vernier cam gears and a Microtech LTX8, as well as extensive head and port work.
    The current turbo I have is good for 215rwkw in a rb25, as it runs a 49mm inducer front, a larger rear exhaust housing from a VG30. This turbo is larger than a GT28RS disco potato(46.1mm) however the only down fall to it is, the ceramic shaft and rear wheel. As this turbo is being bolted onto a 1.6ltr, I can run a lot more boost through it than a rb25 could. Im trying to push 22+psi through the turbo into achieving the power I want to make which is the power mentioned above.

    Just a point of interest on torque from a 1.6L - Theres an old issue of Hot4's with a silver mirage on the cover.... anyway.

    Its got a 1.6L Mivec motor with a wipple SC bolted on... now it makes something like 210-220Hp @ the wheels.... but the torque is 740 something Nm......... thats pretty amazing, the boost isnt even that high either.

    back on topic.
