N75 knowledge needed

[birch1983]

I wondered if someone can give me any advice on this. They aren't a valves I'm really knowledgeable about but I've been told if you fit the correct one gains can be found.

I've just been offered a ECS N75 Race Valve and wondered if they are worth the swap. I currently have the later variant which I think is an E. Prior to this I think I had the F variant but this was shot hence the change to the later spec one.

Thoughts and opinions please guys.

Stick with a standard N75 and get the car mapped with maybe some upgrades (injectors,maf,fmic etc) to achieve a proper gain !! Any other n75 just brings the boost in to harsh and doesnt show any significant gains overall !!

 

[birch1983]

What injectors do people tend to go with and what is the MAF upgrade? May consider a change of plan. ;-)

those components need matched to the turbo you've chosen and power level your aiming for.

I'm thinking of heading down the ko3s route and aiming for about 230-250bhp. Really trying to get together a shopping list of bits I'd need.

K03s on an A4 doesnt really exist.

What car do you have? Year? Engine?

I suppose you have the K03-073 from the B6 BEX lump, could be classed as a K03's'

It is a 98 AEB. Was advised I have a KO3 and that a KO3s would be a nice easy straight fit. :-/

Yeh, the problem is that the "K03s" isnt really that common on the A4. As rob says, the B6 190hp motor has it, but they're fairly rare. On the A3/Golf most cars were fitted with them after a certain year, so they're fairly ubiquitous, but the A3/Golf turbo doesnt fit the A4.

IMHO your far better getting a hybrid built by beachbuggy, you can fit much larger parts inside the stock housings than you'd get with a K03s and you'll know its new.

S3 or RS6 turbine and an RS4 compressor wheel and you should have a turbo capable of 250hp or so.

C20LET injectors, 3 bar regulator and a VR6 MAF housing will go nicely with these parts.

Thanks for the heads up. I wasn't aware of the availability of the KO3s' so i may actually consider the option you mentioned. I've been looking at some Saab Red top injectors. Would I be correct in saying these would also work well?

Is beachbuggy a resident on this forum?

 

[aragorn]

yeh saabs are a little bigger but would also work.

beachbuggy is a member, he also has a facebook page if you google for beach buggy turbos you'll find it.
