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)

    • Check the injectors flow evenly, and are actually flowing what you and the ECU think they should be flowing. If it's starting up on starter fluid, you have a fuel issue. Is it possible under cranking your fuel pump is turning off?   The harness you replaced, is that the whole engine harness? Do yourself a test, and drop the old harness on and plug it into the Z32 ECU. It's possible they've wired things different. From memory S1 to S2 is different in RB25 and you may have a wrong loom
    • I haven’t pulled the injectors to watch them spray yet but they are clicking from the cas and all of the spark plugs are wet with fuel. I’ve thought the cylinders were being flooded from the beginning and was hoping fuel pressure would fix it. Tonight I am going to pull the rail and watch the injectors spray. Don’t know how to test/diagnose if the plugs are firing in correct sequence but that should be a timing thing and as far as timing goes my car still has the half moon for the cas can only install it 1 way. And my mechanical timing is 100% correct I posted photos above. Confirmed with the balancer on and off. 
    • I checked spark on all cylinders and they all visually have spark with the plug pulled and grounded, but plug 1 is the only one that fouled. This was a running swap that blew up and was rebuilt by a machine shop, put a new wiring specialties harness and did all gaskets, studs, and bolts while it was out.  compression is 135-150 across all cylinders. Aside from that from my understanding with the z32 ecu and maf the car should start regardless. The wiring for TPS and the dual 02 sensor/ dual knock sensor stuff shouldn’t actually stop the car from starting or even running well, (just slightly rich)  they just give fault codes. Car supposedly is supposed to start as long as you have z32 afm and ecu with the nistune base map and that’s info coming from a well known and trusted tuner who does a lot with SR/RB (Rsenthalpy). After more trouble shooting today where I’m at right now is that the cas is sending signal to the injectors they click while spinning the rotor, Fuel pressure is now set at 43psi, all cylinders have good compression and all of the plugs looked great (just wet with fuel) except for cylinder 1 which was very black (cylinder 1 has 150psi compression). all of the coils generate spark if pulled out and grounded out on the head. On the fuel pump car just pops into the exhaust. On starting fluid car will fire off. Hard to tell if all cylinders are firing off but definitley a couple. sounds like all of them but it’s only for 3-5 seconds hard to tell. 
    • Final update!!! Got the front bar fitted and sprayed and all sorted now. My cutouts worked great and the indicators aren’t just falling off. 😂
