ITzDarcy Posted August 6, 2014 Report Share Posted August 6, 2014 Hey everyone, Just thought I'd post an update to show my progress. Still got a long way to go and eventually want to clean up my z22 block i have and paint it etc and replace the z24 with a shiny z22. Cheershost imagefree adult image hosting adult image host post img Quote Link to comment
ITzDarcy Posted August 6, 2014 Author Report Share Posted August 6, 2014 Going to be buying electric fans and also alot more. But if you have any tips or recommendations please do.Still have msd ignition booster to install. A few good months ahead cheers. Quote Link to comment
_chiefjt Posted August 6, 2014 Report Share Posted August 6, 2014 What I've gathered to convert out z24 to electric fan. If you didn't know already. lol Electric Fan upgrade/conversion: 1978 280z water pump Late model d21 or early model Frontier KA24E pully Water pump bolts- x4 6x1.00 approx. 18mm long, x1 6x1.00 80-90mm long, x4 6.100 10mm long hex style for cleaner looks Loc-Tite for bolts Quote Link to comment
ITzDarcy Posted August 6, 2014 Author Report Share Posted August 6, 2014 Hmm all I have so far from your list is the loctite. I also didn't think it would be that technical. I was thinking I'd just have to remove the existing fan and install suitable electric fans with a bit of modification's. Haha, As I say appreciate your input Quote Link to comment
datzenmike Posted August 6, 2014 Report Share Posted August 6, 2014 You also need a water temp switch to turn them on and off. The mid '80s S12 has one in line in the lower rad hose. Just need a relay. Quote Link to comment
MikeRL411 Posted August 7, 2014 Report Share Posted August 7, 2014 You have a perfectly servicible mechanical fan already and no reason like "I am out of room between my radiator and engine block", so why not just add small electric fans in the lower left and right corners where they would give more bang for the buck and leave the current fan alone?

datzenmike Posted August 7, 2014 Report Share Posted August 7, 2014 Right now a shroud would do more for it. Quote Link to comment
_chiefjt Posted August 7, 2014 Report Share Posted August 7, 2014 Agree. Plus you might have to upgrade that alternator to help power up the electric fans. If you want it to look clean then yeah it's a little technical but I've seen 'em cut off before. But I'm still gonna do the swap regardless just cause I like it. lol Quote Link to comment
ITzDarcy Posted August 7, 2014 Author Report Share Posted August 7, 2014 I like the idea of the small fans. Because I know its going to get a bit hotter in there I just wanted I bit more cooling. I have the stock shroud, I still have to reinstall it. Went and bought all the pieces for the turbo oil feed line today. Will be awesome to get it on and oil running through that turbo. Combatting pre detonation is going to be very interesting.. . Quote Link to comment
Nissan_Boy85 Posted August 7, 2014 Report Share Posted August 7, 2014 Can I get some info on the intercooler? Basically dimensions, inlet/outlet size, if it came from something readily avaliable, etc. Quote Link to comment
datzenmike Posted August 7, 2014 Report Share Posted August 7, 2014 Combatting pre detonation is going to be very interesting.. . Deal with detonation before you have it rather than after. This is caused mostly by excess heat where you don't want it... the combustion chamber. Basically you are making a diesel engine that fires from compression and concentration of heat in the air. Oil cooler... removes internal engine heat from hard to reach areas. Large enough rad to prevent heat spikes during prolonged boost Cold air intake. No sense running already warmed air from behind the rad. Inter cooler. Removes heat from the compressed boosted air. Alcohol/water injection. Absorbs heat in the air by evaporation Quote Link to comment
ITzDarcy Posted August 8, 2014 Author Report Share Posted August 8, 2014 Does anyone think having a sufficient oil cooling system and rad will be enough to stop detonation? As the oil cooler is alot cheaper than alcohol injection? In reply to nissanboy85 I'll have to get the dimensions for you .. but its just a custom small intercooler no logo or brand.

banzai510(hainz) Posted August 8, 2014 Report Share Posted August 8, 2014 Like I said contack keith Law on the 510realm. he has worked this all out on a weber DGV with turbo Quote Link to comment
datzenmike Posted August 8, 2014 Report Share Posted August 8, 2014 Keith has his weber in a pressurized box. The weber has been extensively modified to flow more air. Does anyone think having a sufficient oil cooling system and rad will be enough to stop detonation?As the oil cooler is alot cheaper than alcohol injection? It won't totally stop it but will go a long way to preventing/reducing it. Anything, even if a small thing, that reduces the heat in the combustion chamber helps. Quote Link to comment
ITzDarcy Posted August 10, 2014 Author Report Share Posted August 10, 2014 Can I get some info on the intercooler? Basically dimensions, inlet/outlet size, if it came from something readily avaliable, etc. the specs -Core Size: 550x180x65 mm -Overall size: 700x180x65 mm - ID = 2"inlet and 2" outlet - OD = 2.5 " Idk if its good enough but hopefully it does the trick for me, its just a jap custom off of ebay. Came in immaculate condition amazingly. Like I said contack keith Law on the 510realm. he has worked this all out on a weber DGV with turbo ok thanks man i'll contact him and get some info. Keith has his weber in a pressurized box. The weber has been extensively modified to flow more air. It won't totally stop it but will go a long way to preventing/reducing it. Anything, even if a small thing, that reduces the heat in the combustion chamber helps. Ahh i was thinking i'd probably eventually may be forced to have it in a pressurized box and I need to learn a lot about carbys so I can tune it myself as the kits are fairly cheap. Ill keep looking around for successful hat top blow throughs. Once I get this carb issue sussed out and out of the way. I won't put it on the road until I've done as much as possible to contain heat and install cooling systems. Quote Link to comment
jwerty1 Posted August 13, 2014 Report Share Posted August 13, 2014 You don't happen to be have e85 over there do you? It runs way cooler and is very detonation resistant. I actually junked my water/alcohol injection and upped the boost after switching to e85 Quote Link to comment
ITzDarcy Posted August 15, 2014 Author Report Share Posted August 15, 2014 Man I just moved 4 hours from the only place in western Australia that has e85 on pump. I'm going to have to settle for an oil cooler and alcohol/water injection. So far I have planned: Oil cooling system Alcohol/water injection Turbo blanket Exhaust wrap extra fans Cold air intake Any other precautions I can take .. maybe?? Quote Link to comment
