TD05-14B? dunno what housing sizes they do it in tho...think its an 8cm..?!? May be a little laggy though... but should make over 300 horse..can get it both in internal wastegate or for it to work with an external one.

you could even go down to a TD04H-15G/16T/19T all of which should flow around the 300 horse mark.

do you want lag or is that just a by product of what the engine spec is?

I can happily find you something suitable mate, it just depends what you actually want from the engine.

HKS GTRS would be a nice little turbo for that application.

[Guest Enzo]

would be good to know what air the engine can push out,

that way you could find the perfect right turbo for your aplication buy looking at the different compressor maps and cfm ratings of different turbos

i still cant understand how to calculate it perfectly the turbo that has the right efficiently range for your engine,

to read up on what im on about

have a look at this, perfect for finding the right turbo for your aplication

if you can find out how much your air can push out and can read a compressor map its the only way to get a concrete firm choice ideal for your spec, and not on recomendation.

GTRS would be FAR too laggy, they're laggy on SR's rick, hence why they're rated at 400bhp, they do come with some lag.

He's along the right lines with a GT2530, although they're an older design so i believe they're a little mismatched (intake/exhaust), so something along that sort of line but with a better efficiency curve should help.

I'll have a look and see whats available for good money at the moment

cheers bud

Td04 exhaust side mated to td05 this would see good spool with 280 + I would have thought!
