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 .

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
