2.1 550 bhp build
Im thinking about a build in the winter with 550 bhp target
What are strongest components to use List of parts Do i need head work cams valves etc Going keep it twinscroll Car jdm hatch .thanks guys |
Got to be a 2.0 litre CDB built up to a 2.1 stroker, Turbo wise Im not sure they do a really big twin scroll turbo to support 550bhp, but I could be wrong!! Have you thought about some of the billet twin scroll turbos like the SC46, LM450, would make a very fast road car with excellent spool and be just under 500bhp with other supporting mods!!!:thumb:
|
A good mate of mine has a lm450 twin scroll turbo on his JDM and to say its rapid is an understatement lol and he's just under 500bhp and not a lot keeps up with him.

Thats mental Yeah it was until the owens turbo shat itself after 700miles and they wouldn't cover it under warranty due to being over 12 months old.. on to a rotated EFR now just fitting it all atm |

Meth or bigger forged block for next step. |
Cheers fella Bob said if I had big maf intake it would done 460
95 octane map with 3mil nf black per litre of fuel worked out 1/3 btl per 40 litres @ 1.6 bar He also said I'd have get custom maf pipe made cos no one makes it for my car apparantly |
550bhp is way over the top for a road car in my opinion, not drivable to its full potential.
Go to 450bhp tops and save a fortune |
2.1 and push the turbo and make just under 500 is prob the route I'll go with splash of meth

So many options
|
Just go full hog if money's not an option, can always set low and high boost maps for road and track
|
A stock location twin scroll 550 bhp turbo is going to be an absolute pain to even get to fit.
|
I agree the lm450 barley fits in

Personally, I'd prefer a more spooly and more driveable 450bhp than a laggier 550bhp. And nobody could argue that 450bhp isn't enough grunt to swiftly overtake a slowcoach Prius driver and generally have some fun! |
Rotated setup = spooly 550bhp
|
Rotated setup = £s :)
