Wrecking R33, Building R32 Drift Project. Rb20 Rb25 Advice Needed

[d3f3cted]

Heyyyy guys.

i have a r33 wreck at home i have starting stripping which has a rb25det standard in it with low compression and blown head gasket. the engine still runs but overheats slowly and sounds like its running on 5cyclinders. i purchased the car for $1000 so i dont expect much and i kind of got it for parts. moving on.

i just recently aquired a r32 skyline with a rb20det and ill tell you this is the first time i have had a r32 and i like it. i like the r32 more then the r33 but the car is heaps slower then the r33.

could be something wrong i dont know.

a couple of questions i have and i would appreciate as much advice and feedback as i can get from the experts here or people who have done what im doing before.

should i sell the r33 wreck and keep some parts and put them into the r32

or

should i do up the rb20det r32 and sell the rb25det

or

should i sell the rb20det and put in the rb25det after having it rebuilt. i see you can get rebuild kits cheap off ebay and most of the money is going to be labour.

im located in perth if anyone on here can help me out be greatly appreciated.

the rb20det is running without a problem but is slow

the rb25det is running on 5 cyclinders but runs faster and better but im too scared to drive it because of the head gasket and overheating (overheats slowly) dont want to do more damage.

what would be the best thing to do, taking into consideration i have alot of cars and i dont really want to spend stupid amounts of money but it would be nice to get 300-400hp out of one of the engines for under 5-6k

other thing would it be worth putting the r33 turbo on the rb20det r32 and boost it to around 12-14psi

it looks like the rb20det is running 10psi currently with stock turbo as the gauge says.

the car is really loud and looks like the BOV is making most the noise and turbo spools nice.

so currently i have a complete r33 rb25det

and

r32 rb20det

can i make one really good car out of two

or should i just wreck and sell all the r33 stuff and put that money into the r32 rb20det

reason i ask is because alot of guys here are removing the rb20det and selling them to s13,s14,180 guys that are full on with the ca or sr engines and want a RB but not prepared to do a 25/26/30 config

also how much is a rb20det worth

and a rb25det

i got told rb25det sells around $1500-$2000 without box. i dont want to sell the box

i got offered $800 for mine because of the head gasket needing repair. is that a good price ?

sorry for writing a book^ but just trying to get some quality expert advice.

Thanks guys

From my experience, I would strongly recommend rebuilding the 25 and slotting it into the 32. The 25 has "torque to burn", cubic inches still count, and it should be a lot easier to get your hp target out of the bigger engine.

But you will need to factor in a new ECU - you might be able to Nistune a RB20 ECU, but it is probably a better option to get a dedicated aftermarket ECU. (Although you will probably need to do this no matter which route you take)
