Hi my rb25de engine is screwed cause i bolted a turbo on without decompressing the engine and i ran to high boost... but there is a few ways a can go about fixing this problem...

ive been told i can buy a reconditioned engine for $1000 and ill just dump it in

OR

i can buy the bottom half including crank shaft, pistons ect... for $250 these ppl told me IF my head on my old engine is still good all i need to do is bolt it on there half of the engine and away i go i have a good working engine... Now i basically need the top half of my old engine, so would there be anything else that i should be looking at to see if its damaged or broken?

WHAT DO U PPL THINK I SHOULD DO!!!!

how can i check if my head is F#%KED

please give me ur information cause my r33 is just rotting in my driveway and it kills me seeing it like that.

There should be no damage to the head if there wasn't any serious overheating problems, or the engine was run extremely lean and burnt out a valve or two. Swapping bottom ends is a waste of time IMO... Just sell the head off to someone keen on a RB30det conversion and find yourself a nice cheap complete rb25de

thats why if your running high compression, get a good tune :devil:

so what exactly has happened? is it seized, have you shot a rod? f**ked a piston...?

ok thanks for ur info. so why is it u think buying the bottom end is a waiste of time? i dont get my licence back until march 13th, and then i need to buy my rego again which is $1000 im just not sure what is better to spend my money on. to save or not to save, is it worthe the effort of swapping the head over or not cause im not fussed if i have to pull the head off and put it on another, i just want it all to be working decent untill im off my P's then ill buy a RB25DET, so in 2 years the engine will be coming out neways so what would your opinion be on this topic now? please reply... thanks

      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
