What is the biggest sized turbo I can dual on an rb26 cant seem to find anything bigger than tdo6

hks gt3240
IHI RX6R
1,000+hp and cost about 50k for a engine setup like that.

Dual TD06-20g's would be pretty beast - not sure the compressor housings would clear the strut tower, but it'd be interesting to see.

You could always make a twin-T3 setup and run a couple GT30-series turbos to get into the 1000hp area, but most people prefer the spool characteristics of a large single turbo to the "off/on switch" effect of big twins.

Buddy out here with an RB26 in his S13 just went Greddy twin TD06-20G setup...here's some shots if you're wondering about clearance. The only thing is this is on a RHD car, steering shaft was not an issue for the DPs.

How much extra horse did he get from adding those 2 td06s?

I think people are getting the wrong message im actually doing this on a 240z srry i didnt say in the begining. So is there anything bigger that i could do for a twin turbo?

you will be plenty happy with 2 gt35r turbos and it will be fast spool/awesome to mess around with. single turbo will be most efficient for the $ to make large numbers. so if you want to pull highways or drag id go single.

Still working some surging issues but should be sitting around 700-750 depending on how much boost he squeeze out of it with the wastegate he got.

You can go as big as you want, problem you'll have is finding a manifold to support the turbos and having enough space for it. You got the strut tower to worry about and then you have to figure the downpipes to clear the LHD steering shaft. Biggest reason folks go big single turbo is due to the lack of room.

Do you think it's better to go with just a single t88 or something like that??
