Most definately yes it's a good idea. A lot of people on these forums have done it and haven't looked back. The lighter weight of the 32 and the extra power the RB25 gives equals a hell of a lot more of a fun ride. Do a search on the forums, I'm sure you will find a fair bit of info, I know for a fact I saw a thread today about it but for the life of my I can't find it!

Not sure on the price buddy, I haven't looked into it myself but keep in mind, does that include the RB25 gearbox also?

As for Regency, I don't think it's a problem as long as...

A) You let them know

and

B) Make sure your brakes are capable

But just to be sure, call them and find out :mellow:

i put an rb25det in my 31. Best thing i ever did. rb25s are such great motors. Id check with regency also, may need to get engineers cert coz of increased in motor capacity, power etc. Definetly worth getting rb25det box. rb20det one will last a while but not forever!

if u buy a Rb25det box make sure the synchros between 3rd and 4th aint f**ked. if so ull be using red line shock proof like me till u need a rebuild of the trans or just new synchros put in and still a >1500 job.

ok jms have quoted me $5500 for rb25 supplied and fitted!! is that good or do u recomend somewhere else???

Yeah thats not a bad price but still shop around at Nisswreak and Zimports for prices

But just to be sure, call them and find out :happy:

Bigger brakes are always a good thing and with regency I thought all you had to do was swap the engine numbers over but could have changed now and need to get the engine converstion approved

Hope it goes well :stupid:

Yeah Ive done my research on the r32 rb25 conversion, 5500 is a bit much for just the engine supplied and fitted. You can pick up an rb25 + gearbox for 3000-3500 and most places charge between 1200-2000 for labour. Contact predator, he has his own site for the conversion and can help with any questions. The gearbox isnt essential unless you plan on going over 200rwkw.

hey thanks heaps guy looks like u have gone out of ur way to help! its much appreciated! thanks guys!!! ALSO.... d1 garage quoted 5200 for series 1 rb25det with rb20det 5speed, and 5500 for series 2 rb25det with rb20det 5speed....

QUOTE:

To give you more accurate price we will need to see the vehicle here at the workshop to check everything is in good order to complete the conversion.

The conversion price will include new engine oil / filter, spark plugs, coolant, fuel filter, gearbox oil, and diff oil.

To drive in drive out fitting an RB25DET complete engine package and using your original RB20DET 5 speed box (providing its manual) will be $5200 for a RB25DET series-1 engine and $5500 for a RB25DET series-2 engine.

thats what they had to say!

ALSO is the engineers cert extra ontop of the engine/install?

      Coolant leak?

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.

      Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo

      Hey all, Recently have had my s1 r33 gtr serviced and noticed my coolant reservoir was topped up to the max line. Took the car out for 1 yesterday and noticed today the reservoir is completely empty.  Any ideas? Radiator is full
