hey

i bought a gts4 motor to put into my r33 gtst i still wanna run rwd

i was unawear that it was a s2 or at least it is a lil diffrent to my engine and mine in a s1

i was under the impression i could remove the sump and trasfer case and put the standard sump on but the bolts a alot bigger on the sump and wont do up

- would i be able to fill the holes and re tap them to teh sizes needed

-also being a s2 motor (thats if it is a s2 motor) can i remove all wiring and coils and put my wiring and coils in and still run normal

the fly wheel is alot thiner than mine

im doin this as i have taken the motor out of my car and putting a standard one in but couldnt find one at the time for a good price

can anyone help me please

atm i have stripped it back to nothing only internals head is on and im about to change sumps any help would be great

mm... your wording there isnt too good :sleep:

Is the GTS-t sump bolt holes bigger or smaller than the GTS-4 sump?

Either way, you either mod the GTS-4 sump and lop off the diff (no great drama for a half decent fabricator)

Or just mod the GTS-t sump to suit the holes.

I wouldnt be playing around with the block, i'd be playing with the sump

the gts4 sump holes are bigger than the gtst ones

would the volume of oil in a sump of a gts4 be any diffrent to a gtst sump ??

cause i was just goin to do wat you said chop off the side and fab it up

Isn't the gts4 r33 an non-turbo motor? ie higher compression and a few other changes standard?

at first i thought it might have being but the seller assured me it was a turbo

when i got it i checked for turbo oil and water lines and they were all there so im guessing it is

can someone correct me if im wrong please

can someone check the engine number for me ??

So drill the GTS-t ones out, and fit it.... Or is that not an option?

I havent seen the two side by side so dont know if its an option

It would be the cheapest if it is though.

If not, just lop it off as i would imagine it to be the same/similar to a GTR one.

Im running a modded (diff removed) GTR sump on my RB26/RWD and capacity is little to no different im told and its going to be predominately circuit driven :sleep:

hi,

when we swap 4wd engines into rwd cars here -- we just cut-off front diff part from 4wd sump. already done this three times -- no problem.

enr33 never was a turbo, maybe your engine is from first generation wgnc34 stagea?

to swap s2 engine to s1 car you have to change ignitor (there is no one @s1), coils, maf, tps. If you are really unlucky and you have latest s2 with hitachi CAS (black plastic case) -- then you have to change CAS and exhaust camshaft.

to quote your link.

"Next was the RB25DE, a 2.5l engine with 190hp at 6400rpm, powering the GTS25 and GTS4." note gts25, not gts25t.

Doesn't change anything for you, just look in the stagea part of the forum for more specific information on the motor that you have and what you have to change for fitment..

Personally for the sump I'd be doing what r31nismoid and stronzo suggested.

      RB20DE NEO smallbox clutch.

      By Kapr · Posted

      For once a good news  It needed to be adjusted by that one nut and it is ok  At least something was easy But thank you very much for help. But a small issue is now(gearbox) that when the car is stationary you can hear "clinking" from gearbox so some of the bearing is 100% not that happy... It goes away once you push clutch so it is 100% gearbox. Just if you know...what that bearing could be? It sounding like "spun bearing" but it is louder.

      Yeah, that's fine**. But the numbers you came up with are just wrong. Try it for yourself. Put in any voltage from the possible range and see what result you get. You get nonsense. ** When I say "fine", I mean, it's still shit. The very simple linear formula (slope & intercept) is shit for a sensor with a non-linear response. This is the curve, from your data above. Look at the CURVE! It's only really linear between about 30 and 90 °C. And if you used only that range to define a curve, it would be great. But you would go more and more wrong as you went to higher temps. And that is why the slope & intercept found when you use 50 and 150 as the end points is so bad halfway between those points. The real curve is a long way below the linear curve which just zips straight between the end points, like this one. You could probably use the same slope and a lower intercept, to move that straight line down, and spread the error out. But you would 5-10°C off in a lot of places. You'd need to say what temperature range you really wanted to be most right - say, 100 to 130, and plop the line closest to teh real curve in that region, which would make it quite wrong down at the lower temperatures. Let me just say that HPTuners are not being realistic in only allowing for a simple linear curve.

      I feel I should re-iterate. The above picture is the only option available in the software and the blurb from HP Tuners I quoted earlier is the only way to add data to it and that's the description they offer as to how to figure it out. The only fields available is the blank box after (Input/ ) and the box right before = Output. Those are the only numbers that can be entered.

      No, your formula is arse backwards. Mine is totally different to yours, and is the one I said was bang on at 50 and 150. I'll put your data into Excel (actually it already is, chart it and fit a linear fit to it, aiming to make it evenly wrong across the whole span. But not now. Other things to do first.

      God damnit. The only option I actually have in the software is the one that is screenshotted. I am glad that I at least got it right... for those two points. Would it actually change anything if I chose/used 80C and 120C as the two points instead? My brain wants to imagine the formula put into HPtuners would be the same equation, otherwise none of this makes sense to me, unless: 1) The formula you put into VCM Scanner/HPTuners is always linear 2) The two points/input pairs are only arbitrary to choose (as the documentation implies) IF the actual scaling of the sensor is linear. then 3) If the scaling is not linear, the two points you choose matter a great deal, because the formula will draw a line between those two points only.
