ok, so now youve wetted my appetite and ive been looking at bloody nissan diesels on google, wiki and ebay lol.

few questions

have you pics of the diesel rods? are they beefy enough to run big power? dont fancy the guy that used shot peened CA20 versions, they are too weedy!

also have you pics of the CA20 and CD20 sumps please?

i can see some scrapyard hunting soon and a garage full of more old engine bits!

did the guy contact you re teh crank brace?

cheers

rod pics are here but I think they are too long for the ca20e 223.5 mm block as the cd20 is 228mm so would need 5mm shorter piston which would mean you need 25mm pistons big bore custom hayabusas.

dont have the cd20 engine just the ca16,8 & 20 but the sump on the ca20e looks like this one, a little deeper etc. will try and get a pic this week sometime

Just got word from Tommy on US forum the CD20 rods are 140mm c-c due to the beef'd up slugs for diesel oomph which makes them replicas of Ld28 rods only slighly thinner at the big ends.
Ive calculated the Z22e 149.5mm rods are a better choice for the ca20e block using stock det pistons.

it all seems a lot of hassle for only 200bhp at the wheels mate, or is it that you just want to do something different ?.

[datsober]

Its not the 200hp atw that really interests me but great linear torque & excellent response, maybe I dont need the cd20 FCWC with the ladder brace the stocky ca20 NCWC will suffice but 2 liters with low boost & excellent curve to 7.5K rpm. LPG is just cheap here & rids pollution gear which suits an old car with hidden wiring clean tidy engine bay etc. If I make more hp grand but just been conservative as only using fatory log exhaust manifold with an adaptor like this one.

Any chance there are pics around of your record setting ET cylinder head? this is the one area that concerns me.

I would agree that 200is a low target, i reckon the bigger capacity would help spool though, so a bigger than stock turbo but say 1bar, should start to boost at 3k and pll like a train to 7.2k, but i reckon it was see nearer to 250hp with the 8v head. Is not all about the figures though, looking at some of the dyno plots, theres a fair chunk more torque low down so the delivery will be better.

The benefits would be even better with tye 16v head, summat like a GT2871r with 2L capacity would be awesome, 375+ with a lovely wide band.

I fancy collating the bits for a ca20/cd20 hybrid over next 6months, just to learn as much as anything. There seems a lot of differences betwwen the UK primera and van/serena/largo variants so i need to do some breakers yard detective work.

Does seem a lot of faffing about when your FJs making 600-700hp though Shaun
