hey all. i have a S300 turbo brand new sitting here, its the 62mm with a 14cm housing. instead of putting it on as a single i was thinking about waiting till after/during winter and doing a custom twins kit. the only thing is what turbo to match with it. i know all about the HT3B's, S400's and turbos like that. but this is a little bigger than the HX35/HX40 with an S400 on bottom. the HX40 i believe is a 60mm wheel and a much smaller turbine wheel. the turbine wheel on my S300 is a 70mm on the small side and an 80mm on the big side.

i think BD's twins use a 58mm S300 hybrid with a 66mm S366 hybrid on the bottom. i just dont want a laggy twin kit thats going to hurt my towing. i use a GT42R-102mm turbo on my Eagle Talon drag car and i was thinking of spending some money and using one of those, but thats a 74mm turbo( S400 size).

anyhelp would be great. i dont want to fire ring the head, just some ARP's and some injectors and a lift pump is what im looking for.
or should i just use the S300 as a single and be done with it?

Thanks guys.

I have a 64/12 on the top of my twins, the bottom turbo is a B2 or a S400 it has a 132A/R. This twin setup runs the same as it did when I had the 64/12 on it as a single. The main difference is when the B2 lights you better hold on.

The B2 you can buy for under $600.00 from HTT, and it works great.

is that B2 the same B2/S400 that PDW sells?


thanks dieselfan.

 

I don't know if its the same turbo. Mine has a 134a/r with a 5" inlet and outlet.

what is the difference between the S400 and the HTB2? and what size?

thanks

 

A HTB2 is a b1 and a S400 is a b2
