Hi People

Im just doing some research and tryin to consider my options in my head.

My engines running low on compression so i need a rebuild

I could go down the path of rebuilding the engine wif forgie and a whole lot of bells and whistles and make a monster engine.

I could also go for an RB26dett and get alot more power for the same amount of cash

My budget is about $5000.

Im leaning towards the rb26dett in a r33 gtst.

So far engine wiring loom, chassic wiring loom, rb26 ecu..........

Has anyone done this conversion before, if so can you please shed some light on this for me. Its a bit of a grey area for me so ur opions will count.

Im after possible problems after the engine is built and put in and then it decides for example not to start or sumtin like that.

Thoughts!!!

$8k!! Mine cost nowhere near that!

Personally, i'd consider rebuilding the current engine rather than swapping in a 26. But it all depends on you current state of mods (ie, what you can swap over) and what your ultimate goal is.

the RB26 probaly not the best option as if its cheap its cheap for a reason and RB26 engines are very expensive to rebiuld (10K min) so if its a bad motor theres 15K down the drain. plus you would need to modify the sump to run RWD no biggie just another thing.

you would be better i think rebiulding it as then you now it is a fresh motor. get forgies and run more boost.

just IMO

Ah, that explains it. You included mods too.

Mine was sub 3k but only engine loom and ecu, new timing belt, water pump and z32 afm (as i didn't have an afm), swapped in my existing highflow, manifold, emanage, twin plate did new cooler piping, used existing gearbox. Done.

If i included all the stuff i've done since then 7k probably wont cover it :starwars:

      I'm not 100% how the BMW racers do it, but I know from other brands like Merc, moving, and changing the coolers is one of the things. Like getting a transcooler out from infront of the radiator to out near a wheel arch. So some of the stuff you've got crammed in the middle front, spread it out and open up where you can in the bar to get more air in to the sides.

      Small update for the day... Turns out the intercooler and engine coolant hose kits are anything but complete....I probably should have counted better but it only really covers about half the coolant hoses in the car, it really just covers the visible stuff and pretends everything else doesn't exist (turbo water feed and returns and also heat exchanger lines through the 2 pumps and cooler) .In any case, I'm happier to have half reliable hoses than none, but a bit of a disappointment. Anyway...finger click (and 5 hours).....hoses in place, lots of spring clamps replaced with screw clamps, and engine coolant is on the pressure tester for the night.   Incidentally, upsized header tank is an Inifiniti factory option....not sure I'll ever do prod car racing in this but at least it is legal.

      Just weld it onto the hot pipe. If you want it right after the turbo, put it right after the turbo. Or rip the comp cover off and drill and tap a hole into it.

      hahaha glad I can rely on you two to go on a spiral at the drop of a problem! Some quick answers....the ducting is excellent top bottom and sides....everything that gets in goes through the coolers (noting the oil cooler redirects it out again, fair call if it is cooling 120o+) and the heat exchanger for the intercooler also has some scoops to pick up more than it's fair share too. I can't see going down the water spray track....no bueno for formal racing and a big risk for long rally days if you run out (plus I'm not clear if it is allowed there either yet).   Frankly, it must be possible to reliably put 400kw through a standard front end, the BMWs do it so I just need to work it out....I'm starting with reducing blockages in the way and adding some coolant capacity with a bigger header tank, flushing rad and making sure it was filled/bled properly (I didn't do the last coolant change); also taken measurements incase next step is a bigger/higher capacity custom radiator

      wow, a completely stock GTR! I've got to admit, I have no idea from what you are describing....do you have  any idea where the "thump" comes from, and are you certain it is the HICAS light not something else like the cat overheat light?
