Redtop Nics Power Output

The general power output figure for an rb20det is 215hp, but I'm assuming that is the silvertop ECCS.

I am looking at putting a redtop NICS engine into an r30 with a dr30 brake upgrade, I need to know whether it exceeds the FJ20det output or not for engineering info.

The FJ20det is 190hp and the RB20det is 215, the redtop rb20det has to be inbetween there somewhere within reason, I need to know what it is.

Thanks,

Rick.

I believe the Nics is around 135kw compared to a silvertop 160kw.

So the Nics has a little bit less power than a FJ20.

Ahahaha, that's both good and bad to hear... :)

Well it's a good thing considering this will be the very first turbo car I've ever driven let alone had. Because, I probably shouldn't have too much power.

At the same time that makes it kinda annoying...

What sort of kw rating does the FJ put out?

And what is the NICS horsepower rating?

Cheers!

Rick.

It's gonna set me back bugger all and I don't have enough money to do otherwise so I'm content with the idea. Put it this way, regular mr30 = 85rwhp, I think. NICS = 150rwhp in an r30 with an exhaust (I'm pretty sure on that) That jump in power alone is a fair bit and should be enough for me to get the car to do whatever I need to do with it.

Also the turbo 2-door R31's have the NICS engine and weigh 1350kg I believe whereas MR30's weigh 1150kg's, so that should allow for some more power access.

Yes, but the NICS are plagued with electrical problems... most of the red-top RB20's are.

They werent the latest and greatest and a brand new motor design which was much improved/ironed out with the silver top, which are far more reliable.

You might be lucky, you might not have a problem... but it potentially might be a cheap motor that ends up costing you much more than you expected

Good point, but at least for the time being, this is all I can afford. I've seen it running and everything 'appears' to be in well running order, so hopefully I am lucky.

I'd think very hard before using that engine . People here are trying to stop you painting yourself into a corner with the early R31 spec RB20DET . It would make more sense to save a bit longer and buy an engine that not only works better everywhere , is easier to get parts for and comes standard with better manifolding/turbocharger and engine control electrics . Just to get the non std engine and gearbox into an R30 is going to take a bit of effort and money so why go with a known problem child .

Cheers A .

A) because I'm getting it for $500 with help in instalation

B) because the engine is being taken out of a 240z and all if any adaption process's should already be done (I'm told the only real adaption is with the gearbox). As for gearbox mounts I'm using a standard MR30 gearbox, however it's in good condition and Bazz from Datsport said it wont have a problem so long as I use decent gearoil in it.

C) I only really need it to last me a year anyway.

D) The body of my project car is delapidated and thus putting a $2000 engine/gearbox into it wouldn't make much sense to me.

D2) Maybe when I get it complied with the weak NICS engine, I give it a decent paint job (going with a can fixup for now), have learned how to drive with a dodgey turbo engine; then upgrading to a silvertop would be a better idea.

Call me ignorant and arrogant and I guess I am taking a chance on this engine holding up for a year, but I think I blew my dailys engine the other day and god knows I couldn't be bothered rebuilding another one for its tainted wishbones, dead front shocks, dead clutch and broken windows at 300-500+ effort for the power of an L24.

I think I'd just find a usable injected L28 and plonk it in . Spending on dying cars is not real good in my book . You're probably better off trying to find another acceptable MR30 and buying one cheaply .

Cheers .

And so says the latest deserter from the classic brigade :)

Some of us still believe in old vs newer, to be better.

Merry Xmas & happy new year A, guess we will catch up again in the new year.

Red top NICCS were rated @ 142Kw @ 6200 but all the tests done on them in Oz say they're stuffed over 5000 rpm so I guess you would be looking at a realistic figure of about 120/130.

Cheers, D

Yep thats due to the standard turbo, runs out of puff just after 5000rpm on stock boost (8-9psi) and drops to around 5psi at 7000rpm, thats why you see most of them run a RB25 T3 these days.

The Zed guys in the states had the same problem with the T03 on the L28ET. As it neared closer to the red line the further the boost bled off, so nearly all quick Zeds use an EBC to overcome the problem.

Cheers, D

      Stock rb25det neo questions

      By Wazmond · Posted

      Hows your intake piping? Are you still running stock? Having in the stock AFM position would mean, if the BOV was shut/venting out, it'd create the almost stalling kind of effect right // "the rich pulse behaviour" due to MAF thinking air is flowing ? But this would be better than having the bov in the stock position + MAF on/just before cross over piping right?

      Essentially, yes. Although I wouldn't put the AFM on the crossover pipe. I'd want to put it into what amounts to the correct size tube, which is more easily done in the intercooler pipework. I bought a mount tube for card stile AFM that replaces the stock AFM - although being a cheap AliExpress knockoff, it had not flange and I had to make and weld my own. But it is the same length and diameter as the stock RB AFM, goes on my airbox, etc etc. I don't have a sick enough rig to warrant anything different, and the swap will take 5 minutes (when I finally get around to it and the injectors & the dyno tune).

      So to summarise, the best thing to do is to move recirc to between turbo and IC, and maf on the crossover pipe. Meaning I'd need a recirc flange, drill a hole in the piping on turbo outlet area. And drill hole on crossover to fit/weld maf sensor? Either that or put the MAF on the turbo inlet right?  Is an aftermarket recirc/blowoff valve recommended? Do currently have family in Japan so could probably bring something back with maybe a cheeky lil SuperAutobacs run?

      Lets play a game - What is causing my oil consumption?

      By tsuokun · Posted

      Yep, so far most have said that it looks like corrosion on the wall from piston not moving. Which then has probably damaged the oil rings and caused those vertical marks. The longest the engine was still after the rebuild, was the winter of 2018 - 2019, plus the boat trip to Japan. When I shipped the car, it had normal gas in the tank but before that winter pause, it had E85 in tank.  In any case, even if either one of those was the cause, it happened close to 6 years ago and the car has been driven something like 30 000kms after the fact. Again, apart from the plugs and the dip stick, there is nothing in the way the car runs that would indicate what has been going on in the engine. I am going to consult a shop and ask their opinion, what would be the best approach. I do have some access to a garage I could use to diagnose further myself, but time is very restrictive. Might end up buying another engine that could be used while this one is being remedied. Without pulling the head, it will be impossible to find out if it needs another bore, but here's to hoping a hone would suffice.  Goddamnit, I would really have preferred this not happening.

      Got this r31 silhouette flood car to rebuild.

      By 25RBGT · Posted

      Boot is going to be replaced eventually. I just wire brushed what I could and rust converted. Then painted in rust kill primer. the spoiler also got repainted and plugs replaced on the ends. The under side of the bonnet is going to be black also, currently white. But red on the top side, same colour code as the silo to begin.
