anyone running solid lifters on rb20det?

[blues14]

a shop down the road from my house has a set of solid lifters for the rb20det. does anyone have them? are they worth it?

[Cornloaf]

oooh how much - i have been looking into that. not nessecasry unless building out to big HP

[Carl H]

wow what kind are they.better question, are you going to be spinning that motor past 8.5k?if not then keep the hydros.....

[themadscientist]

if they are new ok but if they are not don't. Lifters and cams wear into each other so if they are mixed up later you may see accelerated wear of your cams and lifters. For that reason new or reground cams are best. Make sure you set the lash properly, solids need a little more because there is no hydraulic cushion.

well i guess i should have said just stick with new hydros, which is what i was thinking......soild lifter cams require diffrent cams from tomei, the cam profiling is diffrent from what i can discern.

[themadscientist]

That is how I understand it as well. For a street-driven RB there are a wealth of good aftermarket hydraulic grinds from HKS, Trust, Apexi, Jun and Tomei.

[Carl H]

yeah, if you can afford apex cams then great.else tomei make the best cams for the money.hks is like the last resort in my opininon, every car that ive seen running hks cams has had a bad idle due to cams......tomei makes some pretty agressive hydro cams i think 270 with a 8.8mm lift is their most agressive hydro cam, that will be more than enough for most ppl with insane power goals.imho solid lifters are for those trying to make the rb20 rev rotary high, which is cool to brag about but not neccisarly practical.

[blues14]

so with a rev cut, how high can you safely rev an rb20det? I just had my auto rb20 converted to 5-spd and am still figuring out how best to drive it and good shift points.

I usually just rev mine til I feel the power die off which is usually well before 8500 but you can take it there but I wouldn't often. Don't wanna put an extreme amount of pressure on your head that often it just is bad for reliability. Every once in a while is fine as long as you still have power up there which I don't with the stock turbo and head. I usually cut mine around 7 grand. When I upgrade turbo and stuff in the head I may do things differently.~ANDREW~

I am very interested in the solid liftersi've looked into it a couple timesLike themadscientist said DO NOT buy used onesTomei has a whole kit, Solid lifters, Shims, Cams, Valve springs and Retainers

One nice thing that i noticed is that the RB20 and the VG30DETT share springs and retainersI have still yet to find Valves they could be the same as well.

If anyone knows let me know.

But if you still want to rev your motor sky high then you also have to buy a JUN Oil pump and Collar, because on 26's the oil pump is one thing that goes

The JUN oil pump is not cheap either its like 1200 on ebay right now, the N1 Pump is just a stock pump that has a upgraded relief valve spring in there. So dont try that.

well the point here is if you dont need to 9k why bother with solid lifters?hydros will take you to 8.5k which is more than enough and will do it fine as long as they are new.yes oiling at those revs are gonna be an issue, the rb20 oilpump sucks *** plain and simple, anything past 7.5k could be dangerous......if you plan on making the rb20 a track whore atleast upgrade to a rb26 pump and if you have the dough get a aftermarket rb26 one.remember to get an n1 waterpump whilist at it to prevent cavication, but even then past 8.5 you will have problems.

[Cornloaf]

Sorry to ask this question, i have researched and still get mixed answers. Does anyone know for a fact 100% that the n1 water pump will bolt directly on to the RB20DET with no modification? and if there is modification needed, what is it. Thanks

[Carl H]

it will bolt right on, you may need to egg out one of the location bolt holes for it to be a 100% bolt on but for the most part it is indeed a bolt on item.

[Cornloaf]

awsome - thanks carl. i know i can trust your opinion.
