    What would be a better engine to drop into a '82 505 GR?

    G'day fellow frogs,
    What would be a better engine to drop into '82 505 GR to get more performance on a low budget and what mods or changes would I have to make?

    Is there one that would fit right without changing the gearbox or driveshaft?

    Are there other ways to get more performance out of these models?

    The STi engine, or the V6... otherwise you are in trouble with the tailshaft/'link' tube arrangement.

    Would the PRV V6 work? From which model?
    What are the engine specs for the Sti? Is it a PRV?

    well, this is probably not a completely useful answer for you - but perhaps food for thought...

    Some of my mates and I have been discussing that a Nissan SR20DET motor and gearbox would be great to put into nice chassis like a 505.

    You can get the SR20s fairly cheap from Jap wreckers, and it is an excellent motor.

    Of course the job would require fabrication of engine mounts and gearbox mounts, and modification of the originial driveshaft, but the end result would be most entertaining!

    aaah... from reading Ray Bell's post, it appears it mightn't be that simple concerning the driveshaft?

    Yes, you have to do something to allow the 'link tube' to bolt onto the back of the gearbox... but conversions are made of these problems.

    It's all in how you solve them...

    sorry, had to be said

    If a turbo SR20 or even a CA18 (200sx/180sx engine) could be reasonably matched up with a 505...would make an interesting package...

    With the import engines being quite cheap and 505s worth practically nothing these days....it's tempting....almost more tempting than my turbo 504 pipedreams!

    I don't suppose there's any reasonable work around for the brake booster issue that kept the simca turbo engines out of rhd 505s?

    Is an STI engine really worth the effort over a really well "sorted" GR engine? (i don't mean ultimately, just within reason)

    ??????????well then, Am I looking to get a ZEJK engine? What do these engines sell for?

    I have been reading about the PRV V6? Would this be suitable? What about the XN6 motor?

    OK, if you've got less than $1500 to spend stick with the GR engine. Put a WADE 112 cam in it, modify the head slightly, fit a Weber 32/36 carb (or a 38DGAS if you're not too economy minded), fit a big bore 505 exhaust manifold (if it doesn't already have one) and disconnect the anti-poullution air pump (if it has one). This will get you up to about 80-90kW. If you've got a little more money, you can fit an XN6 or XN2 head and inlet manifold and aftermarket injection system to get up to 100kW. You can find plenty of info regarding modifying these engines on my website.

    It you've got $2500-$3000 to spend, either turbo the 2 litre or get a 2.2 litre ZDJL engine and 5 speed gearbox to suit. Here's the mods I'd do to the 2.2 engine to give 105-110kW with good economy:
    -9.8:1 pistons from leaded GTi (i.e. 1985 model), approx $700
    -camshaft reground to leaded GTi specs, approx $120
    -ports smoothed out within 10mm of the valve seats and cleaned up around the valve guides, tapered valve guides, 3 angle valve seat grind. If you do some of this yourself (cleaning up the ports) it will probably cost around $200 or less.
    -after market electronic injection system, about
    $600-$800 off the shelf (about $300 if you build it yourself -see <a href="http://www.bgsoflex.com/megasquirt.html)" target="_blank">http://www.bgsoflex.com/megasquirt.html)</a>
    using a simple MAP sensor system.
    I would use the standard STi oil bath aircleaner because it flows very well and is fairly quiet. The standard diameter exhaust should be OK, but you could probably benefit from a better front muffler design (but not a
    straight-through), like a Walker Dynomax super-turbo (about $130 fitted).

    If you've got atleast $3000 to spend get an even fire V6 from an unleaded Volvo 760 and engine mounts from a 604, or fit some other engine like a Nissan SR20 turbo (alot of work).

    Sorry about that. I'll be more careful about putting website addresses in brackets in future.

    I believe the V6 in a 604 and Volvo 760 are both actually a renault biult V6 so you should be able to use parts from all three on the one project perhaps ???? <img src="confused.gif" border="0">

    Any Weber 32/36 works well on a 505 2 litre. The 32/36 DGAV is standard on 2 litre Cortinas and Escorts. The standard Ford jetting (140 primary and secondary with 160 airbleeds) works fine on standard 505/504 engines (I've tried it). Modified ones should be a little richer in the jets though.

    The Ford Cortina/Escort Webers cost about $60 at wreckers. Kits are about $45, although often they don't need it.

    The standard filter is adequate, but you'll have to modify where it attaches on to the carb, so that it will fit the Weber 32/36 DGAV. If you find a Weber 32/36 DFV (or DFAV) or the Holley version, then the aircleaner will fit straight on. There are plenty of after market air cleaners available, but 99% or them seem to be too small (and thus a little bit restrictive). The K&N filter is OK but it's expensive (about $130). The standard steel aircleaner fitted to some 2 litre TE Cortinas, 1.6 litre Cortina MK2 GT's and the 1975 model Escort 1.6 litre Ghia, is also OK. 2 litre Escorts and most 2 litre Cortinas are fitted with a pretty ordinary plastic aircleaner (I'd steer clear of those). The steel aircleaner fitted to some 2 litre TE Cortinas is larger than the one fitted to the 1.6 litre engines, and is probably the best one, if you can find one (but I'm not sure if they'd fit under the 505 bonnet).

    Almost all the aftermarket foam aircleaners for the Webers are pretty restrictive (atleast the ones that actually clean the air are). Paper or cotton element air filters are the better aftermarket air filters. Oiled cotton ones (like K&N) are the best.

    Oil bath aircleaners from pre-76 504s are good aircleaners, but I don't think they'll fit under the 505 bonnet.

    The standard 505 aircleaner with a K&N element fitted to it and a cold air pipe, would be pretty good.

    With after market aircleaners, when in doubt get the one with the largest diameter. Don't get those stupid little rectangular ones or the ramflow ones (although they do sound cool). The biggest Warneford aircleaner for the Weber 32/36 DGAV is OK (just bairly, it's about 8-10" in diameter). The Redline aircleaner for the DGAV is also an OK size, but it has a top that is fixed on by a large wingnut bolt thing. This screws into a plate which sits just above the carby and pieces of metal can fall down the carby as you screw it in (not good).

    Basically, with the after market aircleaners, I think the largest Warneford one is the best value for money, but like all after market aircleaners it stands out and you could get booked for dissabling the anti-pollution gear. The safest bet is to fit some kind of standard looking aircleaner (like a Peugeot one, or the steel Ford ones I mentioned. The plastic Cortina one has "Ford" written all over it, so it's no good).
