Rb25de+t reliability if done correctly r33 s1

G'day everyone I have a doozy of a pickle. I have built a rb25de+t with good bolt on equipment front facing plenum, big front mount, standard exhaust manifold and a new standard turbo 

the problem is we got the car running okay with a few mods like injectors and adjustments of tps sensor 

so I took the car to a track day to practice drifting and it was going well until it started to misfire cylinder 6 so we found out that I either have a hole in the piston or blew the head gasket or a valve (I'll have it apart this arvo) 

but now I was really happy with the power it put down thinking roughly 200-250 kw and now I'm asking is it possible to beef up a rb25de (a lot cheaper than a det) and get a good tune adjust timing fuel and everything else, I like the power of high compression I'm thinking a thicker good quality head gasket and bolts but unsure how the internals will hold 

welcome to all comments??

Depends on what you mean by "beef up" if by that you are going to throw a decent set of rods and pistons at it and some head work then the sky (or more likely your wallet / fuel system) is the limit. If you are only planning on the gasket and bolts then you will be limited in what you can throw into it safely and that will also be dependent on your combustible of choice (98 or E85). The goal that you have *should* be reachable with a stock bottom end in good condition and reliably so if you are careful with the tune. 

On the bright side keeping your normal DE compression and slightly lower boost might be a good idea to make it as usable as possible - most factory turbo cars these days are shipping with >=10:1 compression for the simple reason that they are trying to make best use of small turbos and create the illusion of a larger motor rather than the laggy huge boot in the pants 1980's turbo experience.

Turns out there is a slight crack in head gasket and was some gunk under the exhaust valve 

in thinking of running e85 on a high compression low boost with 250kw in mind apparently e85 likes high compression?

      That looks good, but I think you're going to need much beefier side skirts now.

      new 1.5 LSD issues/concerns

      I gotta pull you up on this. It's driving me crazy. A shutter is something that closes, like over a window or in a cmera. The word you want is shudder. That LSD is clearly f**ked. Take it to a diff shop and get it disassembled and examined by an expert. YOu might have plates welded together or something equally crazy.

      S1 rb25/s14 starting problem

      By GTSBoy · Posted

      Check the Nistune doco. There are a few assumptions being made here that might not be valid. I will list the things that occur to me: Base map. Base map for what? Base map for Z32? Then the cranking pulse width is probably wrong for an RB25. The extra 500cc of capacity might well be enough to prevent it from catching. Base map for RB25? I don't think you can load one of those into a Z32. You have to just make the settings correct for an RB25 in the Z32 base map. That is either K or the TIM to get the pulsewidth right. Loom. You bought a loom for an RB. And you plugged it into a Z32 ECU. Did you make sure that any iwre differences were swapped. From memory, there's at least a couple. And as per the others, I would suggest making sure that the fuel pressure is correct while cranking and that the injectors are actually flowing as expected. They really must come out and go on the bench, unless you do find that you have messed up as per above points. I would also suggest watching in Nistune to make sure that everything is reading correctly. That the correct binary flags are raised at the right time (like the crank signal), that there's no stupid values in K or TIM. That you have not got mismatched firmware for the ECU and/or a wrong image loaded.
