Finally have found a smashed donor car r33 series 3 4 door with RB25DE so I can ditch the RB20E boat anchor R33 series 1. The mrs is very happy. A few questions.

1. I'm assuming I will be able to use the RB20E manual box with the RB25DE?

Have a RB25de fly. Donor car is auto

2. Will the RB25de Loom plug up to wiper etc in a series 1 R33

3. what engine mounts will bolt up?

4. Tail shaft?

5. Gearbox xmember will this bolt up when sitting behind a RB25de?

6. Any other traps I should be aware of?

The donor car is the complete car so have all the parts I should need for the conversion.

Obviously I will have to do a few mods like auto drive switch etc. I don't have heaps of experiance with R33's but have built many Datsun 1600's with SR's etc and Silvia's. So mods and wiring etc isn't the issue. I don't however want to be stuffing around for hours, would rather a bit of knowledge from people whom are in the know with Skylines

Cheers :(

hey. iv done this conversion on my r33. except i went to rb30de...

the rb20e gearbox bolts up, tail shaft slides rite on it of corse as your using the same box. if you dont have a manual rb25de fly wheel you can use the rb20e one.

you can use either rb25 or rb20e mounts, gearbox crossmenber is fine as as the engine is no longer then the previous.

yes the wiring plugs in to the headlights etc. well it did for me.

the only trap you need to be aware of is the fact that the car will crank but not start because it dusnt send power to the CAS. its pretty easy to do. all you need to do is run a power wire to the ingnition from one of the relays... it helps if you dont have a car alarm to blow up like i did with mine...

is your battery in the front or the back?

dus your car have ABS?

Cheers Mate.

Bat is in the back and no no ABS.

SO I just need to run a relay with the ignition to the CAS? Cheers

its one of the relays by the ecu that has no power. i could have a look for you if you need. its almost been a year since i did the swap. its quite a simple thing to do as far as i know.. its the same thing that people with cefiros that covernt from rb20e to rb20det etc...

its simple for a auto sparky to do.

    • Is there a way to adjust all of the pedals in an R32 GTS-T? they all sit even, but seem to be a little high for my liking.
    • Lucky man, who owns it in the family? Any pics? 
    • The engine stuff is Greg Autism to the Max. I contacted Tony Mamo previously from AFR who went off to make his own company to further refine AFR heads. He is a wizard in US LS world. Pretty much the best person on earth who will sell you things he's done weird wizard magic to. The cam spec is not too different. I have a 232/234 .600/603 lift, 114LSA cam currently. The new one is 227/233 .638 .634. The 1.8 ratio roller rockers will effectively push this cam into the ~.670 range. These also get Mamo'ified to be drilled out and tapped to use a 10mm bolt over an 8mm for better stability. This is what lead to the cam being specced. The plan is to run it to 6800. (6600 currently). The Johnson lifters are to maintain proper lift at heavy use which is something the LS7's supposedly fail at and lose a bit of pressure, robbing you of lift at higher RPM. Hollow stem valves for better, well everything, Valve train control. I dunno. Hollow is better. The valves are also not on a standard valve angle. Compression ratio is going from 10.6 to 11.3. The cam is smaller, but also not really... The cam was specced when I generated a chart where I counted the frames of a lap video I had and noted how much of the time in % I spent at what RPM while on track at Sandown. The current cam/heads are a bit mismatched, the standard LS1 heads are the restriction to power, which is why everyone CNC's them to get a pretty solid improvement. Most of the difference between LS1->LS2->LS3 is really just better stock heads. The current cam is falling over about 600rpm earlier than it 'should' given the rest of my current setup. CNC'ing heads closes the gap with regards to heads. Aftermarket heads eliminate the gap and go further. The MMS heads go even further than that, and the heads I have in the box could quite easily be bolted to a 7.0 427ci or 454 and not be any restriction at all. Tony Mamo previously worked with AFR, designed new heads from scratch then eventually founded his own business. There he takes the AFR items and performs further wizardry, CNC'ing them and then manually porting the result. He also ports the FAST102 composite manifold: Before and after There's also an improved racing crank scraper and windage tray. Helps to keep oil in the pan. Supposedly gains 2% power. Tony also ports Melling oil pumps, so you get more oil pressure down low at idle, and the same as what you want up top thanks to a suitable relief spring. There's also the timing chain kit with a Torrington bearing to make sure the cam doesn't have any thrust. Yes I'll post a before and after when it all eventually goes together. It'll probably make 2kw more than a setup that would be $15,000 cheaper :p
    • Because the cars wheels are on blocks, you slide under the car.   Pretty much all the bolts you touched should have been put in, but not fully torque up.   Back them off a turn or two, and then tighten them up from under the car with the wheels sitting on the blocks holding car up in the air.
