Yes, you should have searched The sr bottom end really isnt the main problem that sr's have. 500-600whp is doable. The valvetrain has issues at high rpm, but there are ways to remedy them. Just like any engine, if you get severe enough detonation, you will lose a piston or two. One of the biggest cause of sr deaths ive sean have been due to oiling problems. There are alot of people daily driving theses cars with >300whp and they are reliable by tuned car standards.
Yes, the j30 lsd will work just fine. No real modifications are needed but you need to try and get the front mounting bolts from the j30. Otherwise you will need to buy some longer bolts and large washers, as the front mounts are slightly different. You also need to swap covers, but no big deal.

 

My housemates SR20DET just popped cylinder 3 at 280hp

They dont all last to 400hp...

 

nissans are pretty notorious to have crappy water pumps, i know my SR does. As in any turbo car, oiling and cooling are the main problems. The SR has a TINY oil pan so an aftermarket unit is a good idea, and a koyo radiator and nismo thermostat should take care of most cooling problems. Other than that, its hard to find a stronger engine!

 

oil problem.. shitty oilpan and dumb oil pickup location... watch for spun bearings...

 

the valve train uses rocker arms that can lead to issues at higher rpms, there are rocker arm stopper kits that remedy this though, and some people dont like the fact that the engine uses one arm for two valves (cant say i know why thats a gripe)

Also, at 400 horsepower that engine won't break (if you're lucky :crossfing), but it isn't going to last you very long either, you'll probably have to rebuild it after a year. They'll take it, but you're really pushing your luck...

 

thanks for all the help everybody. what size oil pan does greddy sell for the sr20det? i had been thinking about buying a upgraded oil pan, seeing as how the stock oil pan is like 3.5quarts?

 

also what head gasket? i thought that most every turbocharged engine had a metal head gasket? i was told that the redtop sr20det doesn't have a metal hg. is this true.

 

yea the greddy oil pan looks huge compared to the stock (still waiting for mine). The stock oil pan is only 3.25 quarts with filter replaced.

The sr20det does not have a metal head gasket as its not needed with the small amount of boost the STOCK turbo can put out. But with turbo upgrades... you should always include the metal head gasket to eleviate any problems the higher compression due to higher PSI can cause.

 

has anybody had any experience with the hks full turbo kit(manifold,wastegate,etc)i have talked to a couple people that said there was problems when fitting the hks manifold's(steering rack)designed for the RHD models? i don't want to dish out $3,000.00+ on a turbo kit and find out it might work.
