sr20de to sr20det - Drifting forum

f.y.e · 23-09-2008, 00:21

just started striping a non turbo silver top sr20de on a mates car and ar planing on using the bare block to turbo, i understand they are high in compression so we are hoping to fit sr20det pistons and conrods and swap the valves over on the head and noticed every thing is internally the same on a sr20de and a non vvt sr20det.

so the question is: to convert a sr20de to a sr20det non vvt, is it just a matter of changing the internals i.e pistons, conrods, valves and camshaft. to convert it to a low compression engine then a high comp. aswell as drilling a hole and adding a feed for the turbo oil drain pipe and lines.

i know what were planing on doing is basically going to be easier to just dump a whole sr20det in to make things easier but i can source the internals for a fraction of the cost to make it more worth my while and have a non vvt engine block so we can create a

non vvt silver top straight cam sr20det lol

and are pulsar camshafts the same as redtop sr20det

Remember you'll have no oil squirters under the pistons as the drillings aren't there, if it's the same as the S13 SR20DE.

f.y.e · 23-09-2008, 15:38

yep we are using a s13 sr20de and it does not have the piston oil squirters for cooling, i was hoping to drill and tap them if it is possible so was wodering is that the only difference in the bottem blocks

cams are different.hydraulic and solid liftered cam profiles differ.cranks are the same,rods the same,change pistons,but keep the n/a cams....theyll be an upgrade over stock turbo cams.

j@garagemac · 23-09-2008, 18:58

why not just get a sr20det block saves alot of fuking about

wheresmejumper · 23-09-2008, 19:01

he already said why....he can get it cheap

j@garagemac · 23-09-2008, 19:02

cheap and hassel vs little more money and ease know were id go

wheresmejumper · 23-09-2008, 19:06

if it was me id keep it high compression and go good fuel

j@garagemac · 23-09-2008, 19:23

until the heads fall off the exhaust valves its just easyer to use a det engine

and at £400-500 for a good tall block its just not worth it sorry to come a cross as a missery but i just dont see the logic

You sure that's not just internet bollocks? I measured my DE cams against standard DET ones and they were similar.

PhatBob · 23-09-2008, 20:23

I've just wasted my time with a DE engine, trust me there's nothing much to be said about them unless you're a glutton for punishment like I am.

j@garagemac · 23-09-2008, 21:04

lol so its not just me, i do love the sound of a sr on bodies but just put a det in there

intake has 8 deg more duration, .5mm more lift.

Stavros · 23-09-2008, 22:11

piston oil squiters are no big advantage, id not worry about them much, just make sure the fuelling and ign is safe, det is what kills 99% of engines, either directly or indirectly

f.y.e · 24-09-2008, 00:45

cheers for the heads up guys, the only reason i am planing on converting a sr20de to sr20det is because i have the block striped and i have the skills to work on it weather it requires alot of hassle (i have all the time in the world) i can just spend around £400-£500 on a det engine and use that OOOOOOOOOR i can spend £130

and use my hands and turn this mother fooker into a sr20deT, if i end up wasting my time getting no were at least i could say to my self 'i tried'

steve_fctuning · 24-09-2008, 00:49

turbo it. (did one of these engines a few years back in a Sunny GTi. reprogrammed stock ecu to compensate for the various differences,) slapped on some pulsar grir bits, t28 and pulsar manifold, fmic and a few other bits, z32 pump n stuff etc etc) boosted it to 9psi or so , went like stink. great fun. Still going strong somewhere around london.

Well I measured mine with digital verniers when I was going to sell my DE ones, and there was fook all difference with the DET ones. That was on the S13 non VVT engines.

Maybe the overall height is the same and the shaft is in a different position in relation to the lobe. I only measured the lobes from end to end and side to side. Alternatively someone had already put DE cams in my car or DET cams in the DE engine, but it would be a hell of a coincedence...

wheresmejumper · 24-09-2008, 12:44

its common knowledge....or so i thought.8 degrees more duration isnt visible to the naked eye.you should have been able to spot the 0.5mm lift difference though.maybe your not great with a verniers??

**Mitch** · 24-09-2008, 12:59

No, perhaps I can't read a set of digital verniers and differentiate between the two numbers, as I'm not all that switched on. Sometimes it's all I can do to get dressed in the morning.
