Hey Ppl

Ive just been doing dome searching on upgrading my turbo. I have found plenty on turbos that will fit the standard exhaust manifold but i can't seem to find a turbo that will also fit the standard dump.

Does anyone know of a upgrade turbo which will fit the manifold and dump.

The reason being is that i have just recenetly bought a BOS importing front and dump pipe, this bolts directly to the stadard turbo with a seperate exhaust pipe and wastegate pipe.

Any help would be great. If i can't get a new turbo to fit then i might consider a GCG rebuild and hiflow for $1900. I'm not really that keen on gettin a new dump made up and selling the BOS pipe as i know i will lose money and im not the richest kid on the block.

What do you guys reckon?

hks gt2530, hks gt2530 kai, hks gt-rs, hks 2835, apexi ax53b70 and some of the trust low end td05's i think should all match the stock dump flange. the highflow will also match. if you are looking at turbo change make sure you have fuel pump, injectors, airflow meter, ecu, clutch, fmic, cold air intake kit and some good tyres to get the best "benefit" from the turbo change. also consider lag vs response. hiflow shoud good best response. boost wont make power, airflow does so dont get a turbo and run 25psi just cos you can, get one that will give you good power at 1.3bar or thereabouts. check the "rb25 turbo upgrade" thread stickied at the top of forced induction. should have plently of info for you

      Yeah I heard the same. Might be hard to order one. But then I guess can go to hks or go to a more expensive n1 block with tomei. Guess will jump the hurdle once I get there next upgrade around. I can’t get work done in the states as the lead time will take for ever on top of shipping to Hong Kong.

      https://www.platinumracingproducts.com/en-us/products/nissan-rb26-cast-blocks This is the solution I was thinking of. I would stay away from Tomei USA, their quality is a question mark to me. If you want an engine machined in the US contact Club DSPORT: https://clubdsport.com/ Tomei JP is probably fine but I recall they stopped doing pre-assembled short or long blocks. In general it's pretty tough to get any kind of RB26 block at the moment with Nissan so severely backordered.

      PAR specifically offers stock ratios in their gearset and you could do whatever ratios are physically possible supposedly for no extra cost. I agree 6 ratios is better than 5, the factory 2nd gear is equivalent to the Getrag 2nd gear if you account for the differing final drive ratio though. The Getrag 3rd gear with a 3.916 final drive is equivalent to a 1.6 2nd gear in the FS5R30A. I'm about to swap the transmission out on my car, I'm tempted to send the one I have now out for rebuild with the standard "cross ratio" gearsets out there to see if it really makes such a big difference the next time I pull the transmission.

      This is what I was looking at next:  https://www.z1motorsports.com/engines/tomei/tomei-rb26-28l-short-block-assemblies-p-45479.html as we can’t bore the cylinders out in hk so better just buy the whole lot in one and install then retune. Everyone saying the weak link are the bolts holding the rods together. I already did valve springs, arp head bolts, hks racing coils, nismo fuel pumps and pressure regulators, injectors etc for the top of the engine.
