I SERIOUSLY doubt you'll find a ball-bearing turbo for under $1500. AFAIK the Highflowed SLIDE turbos are plain-bearing. In fact, I don't know that I've seen ANY ball bearing turbo's around, highflowed, new. or otherwise for under $1500. There's T3/4 hybrids kickin about new for $500 or less, but they're oil-cooled only cores. not too sure on quality or performance either.

hmmmm.. . . . . . .

How does the highflow compare to the std turbo? How noticable is it and how much diff in pwer?

Well mine isn't a slide (I'm sworn to secrecy) but I get the impression it's a similar result in power, lag, efficiency etc. The spool-up below 2,500rpm is possible, but not in the same game as the stockie. Above 3,500rpm tho, it kicks like a frikken Mule ! ! It's definitely not as "ready to go" about town when You're cruisin & give it a prod, but when you've got a few revs onboard to begin with, it's GOLD !

I don't even notice the lag 99% of the time now, just used to it I guess, & automatically adjust/pre-empt.

So its much better than standard (disregarding lag etc)? Both cars I have owned hve been turbo and Ive never upped the boost/changed a turbo before so have never had an idea of how big the increase is.

Lag is not that bad with the standard slide hi-flows, for the small amounts of loss in response there is big time gains in both mid-range and top-end power. Even if you feel it is a bit laggy there are cheap ways of improving response without breaking the bank ie. Retarding ex cam gear, advancing base ignition timing with CAS adjustment, high-flow cats, high flowing mufflers etc.

The power difference is very noticeable, boost hits hard and keeps on pushing rather than plateauing like the standard turbo's do.

Oh I wouldn't bother with a dead-stock Skyline, I drove a few when I bought mine, and it just ain't no fun !

I'm at about 200rwkw, and I'd say that's just nice for a road car (I've got a fat torque curve tho, 16psi boost midrange, 'til the injectors hit 100% at 5,500rpm) but just barely a starting point for trackwork, IMHO. About 18psi and 250rwkw feels REAL fiesty on the road, I've ridden in one a couple of times, and it'll light up both rears in 2nd, straight-line style. =D

The stockie's restrictive exhaust housing/exducer limits flow to 180rwkw, 190 if you're lucky (or your dyno reads optimistically)

Stock turbo comes on smooth & quick, but ultimately won't set your pants on fire. The real-deal "turbo rush" comes from the laggier, harder-hitting delivery of bigger-flowing turbos.

It's fun :/

1. No frount mount.2.Standard clutch ( when you say my clutch should be replced is this because its going to slip from more power? Or your all just assuming im going to be drifting and doing burnouts?)3.Standard fuel system.4. Piggy back ecu ( IS that what the SAFC does?)

I have a turbo back exhaust (with standard dump pipe),

That's not a 'turbo back' upgrade exhaust.

You'll want to replace the front/dump pipes if yours are standard.

If $$ is an issuea (which it was for me), just get an all in one front/dump 3" from flying performance www.flyn.com.au or something similar.

True if you're looking at brand new althought there is/was? a 2nd hand GCG high flow in the for sale in the last few days for $1350 i think and i got my HKS2535 delivered for $1200 from Japan (plus extra expenses on that one though for line etc)

For me, I'd go the 2nd hand GCG over a new Slide but that's just my personal preference.

Yeah Its just the standard dump I have, I have the 3inch Jasma front pipe :/ I will get onto replacing it. Whats better? 2.5Inch split ebay stuff or like a 3 inch single pipe exhaust shop job??

I can never remember which bit is which , front and dump. :/

Do a ring around some zorst places and ask how much to replace that piece then make your own decision.

Yeah will do. Ps dump is right off the turbo front is from dump to cat

Sorry to bring up an old thread guys,

but with this set up - what injectors do you guys use? or what to reccomend?

Ive got the slide hi-flow with other mods like powerFC,EBC, walbro fuel pump

Only thing now that is restricting me is the AFM and injectors

Reccomendations guys?

Cheers,

Chris :)

i have had a slide highflow on my 33 for about 8,000ks now,you can feel more power straight away,but you diffnately need a aftermarket ecu,i have only got the stock computer in at the moment,will put one in soon hopefully,with my car being auto,need to look for a computer that can run the autos well.also will get a high stall,fuel pump etc,but the car and the turbo has good potential to run a low 12sec or even a high 11 second pass,no doubt :P

      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?

      Leak from Tokico BM50 Brake Master Cylinder

      By GTSBoy · Posted

      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/
