Rb25de Engine Info Please


Recommended Posts

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

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

    • Atessa will work the same as it’s operated by a different ECU. If you want to use one so it can be RWD only I’m not sure that will work and if it is what you want then using a GTST or GTT gearbox would be a cheaper and easier tho v to use. You can just use the AWD gearbox and leave out the shaft that goes from the transfer case to the front diff for full time RWD. Changing the ecu and wiring just so you can use a nistune? There are better options out there that are plug and play to your existing harness connector and they should all work if you are running a manual instead of an auto. 
    • @GTSBoy just to make sure everyone is on the same page: OP is doing the manual conversion on their S1 Stagea
    • hey guys i have a 1996 r33 gts-4 and i assume the last owner has been playing with the horn and it’s not working i’m not too sure why the horn pad feels almost springy and feels like it doesn’t sit right is there anything else i would need to tighten apart from the two bolts on the side and or plug in? here’s a video of what it looks like 67842678749__9E03EA58-0C80-4CDB-83EE-5BE6F2D07AC4.MOV
    • The racelogic is one of those things (along with an Accusump) which blows my mind how they don't have wider adoption. They are simple and have massive, massive, massive effects and if you're even remotely interested in driving a car hard, you'll smack your head for not doing sooner. Disappearing in need now as cars get newer and TC technology in OEM's is obviously very competent, but you'll look back at all the years of high powered RWD cars and be like "wtf why only now"
