Light Exhaust Or Big Exhaust?

[Kaido]

Your after something thats 3.5" then dude IMO from what i saw with mine.

3" will *get you by*... but ideally for that its 3.5" and it would be spot on the money

Thanks for the advice, I might just have to get by on the 3"...

For once I'll stick my ore in and please no offense ment .

You mention that you have a 240 SX S14 so it would have had a KA24DE fitted std . These would have to be a fair bit lighter and obviously shorter than an RB25 for not much less capacty - I think there's about 60-70cc in it . A lot has been done and lots of goodies available for the KA 24DE in the US . Jeff Raicer from Full Race is making really nice exhaust manifolds for them and with current trends in twin scroll turbos they can make very strong torque from nowhere revs . With the right bits they easily rev to 6500 a pull like a locomotive . There are here and no doubt Stateside bellhousings for the larger gearbox so no issues with this .

I guess the RB 6 in S 13/14/15 is appealing but the weight and bulk (and sometimes cooling) issues are not insignificant .

Cut my tongue off but I'm even wondering what a properly developed Turbo or KA24DET would be like in an R33 . Food for thought .

Donning flack vest and ducking , cheers A .

You can always put the much better FJ20ET with a properly developed turbo

FJ20's are getting to be an old world engine by todays standards and have a few things against them .

I no longer miss the dinosaur management and ignition system or the overly complex double twin row cam drive system .

They are heavy and bulky compared to most 2L turbo 4's and can create handling and cooling issues in smaller cars . The KA is based on closer L Series bore centres than FJ20's and has one single or twin row chain . The KA DOHC head casting is much simpler than the FJ's mainly due to improved casting techniques . I can't remember if they use hydraulic buckets or shims but they are a real twin cam ie direct cam loab on bucket like the FJ20 .

To each there own but I think in the 2L vs 2.4L stakes the larger is going to be the better when it comes to making torque in a road car .

Anyway bowing out here as I'm already way off topic .

Cheers A .
