Question about Twin turbo kits

phunk

Looks like its based on the GTM manifolds if I am seeing correctly. Perhaps they just buy the manifolds from GTM and make their own kit from there.

If you goal is only 410rhwp, than you barely need to worry about the fuel pump. The stock fuel pump will probably make it this far, but they will probably use a Walbro 255 anyway and that is more than adequate and very inexpensive. I would only ask them so you know whats in there in-case you aim for more power in the future.

For fuel injectors, as long as you are 550cc or larger you dont need to worry about it. Only a modern 48mm body length fuel injector will even fit in there anyway, so you arent going to end up with some old crappy injectors. Again, I would only bother to ask what size they are so that you are aware what is in there if you decide to go for more power later.

The stock fuel system with just injectors and a walbro 255 is MORE than adequate for 450rwhp or below.

Oil cooler is a must. Clutch and flywheel is a must. Boost controller I would avoid, just put in the proper wastegate springs to achieve your target boost since it will be low. Add a boost controller later when you seek more power down the road. If you have a stock LSD, I wouldnt bother upgrading. If you have the open diff, then you will need the LSD.
