Hey guys,

Could i get some info on what a high flowed turbo means please? Is this something you get done to your original turbo or is that how aftermarket ones are made??

Any input would be appreciated.

Cheers

The way i have always taken it as being changes made to an existing turbo, the company makes it then someone else bores it out for more air flow. like when i had my mazda mx6 with an IHI 12 i think when i got it rebuilt i got it hi flowed which ment boring the walls of the copression housing out so it had more air volume.

im happy to be corrected tho if im wrong

Cheers

yea nugget is correct. Maybe pm a few of the guys as to the cost and what specs they had done as Race_Snooze and Tridentt both have had them done to there stock turbo's (although i think snooze got rid of his straight away)

The other thing is maybe give GCG a call as they are the ones who do it.

Cheers Leigh

Yeah well i want to find out some prices to see if its worth while instead of spending $1500+ for a new turbo. Also, will i need to get new injectors if i high flowed my turbo? Would it increase the power that much?

Speak to slide on these forums. he can hiflow your existing turbo for around $800.

for this you get brand new compressor and turbine wheels new CHRA and bored out compressor and turbine housings. it will flow enough for 250rwkw.

I am getting one done right now and will have it in about a week. I will keep all posted on the results.

it is on an RB20 so I will have to settle with 220rwkw bit is should be a screamer.

So seeing as i have a fuel pump, power fc, FMIC, pod will i have to upgrade my coils and injectors to run a high flowed turbo?

EDIT: My current injectors are at 80% and apparently that is maxed so i'd have to up grade them wouldn't i?

injectors no, coils maybe it depends on what state there in the, but injectors will easily handle 250kw

Had mine done [just sold it recently] was really happy with the power, I had 240rwkw at 18psi before I put cams in.

Then I put cams in and [unfortunately] didn't stop there, I pulled my turbo off and sold it [had a very good offer with no hassles] now I'm looking at other turbos etc.

But the high flow was a very good turbo and I estimate would have made around 260rwkw all up.

The turbo is openned up to breath a better. Mine went from 51.2/71 to 56.3/76mm. But my turbo was not a std one to start with, it was a garrett something or rather [not too sure but it went well].

Steve I'll send you my spec sheet so you can see what I have on my 'line to make the power I did. Also if you go to the RB25 turbo results thread in forced induction you will see what other ppl are getting from theirs.

Personally, a high flow for $1000 is a good option. if it goes over this amount then i'd be looking at the garrett GT3071R IW with T3, Slide is selling them for around $1600 and they are a 480hp turbo, so you would be looking at 250-270rwkw with supporting mods.

I'm looking at the HKS2835proS, its a small mods only bolt on. But I'm also looking at the GT3076R IW and the GT3040R IW they require a lot more mods [custom intake and dump and well as oil and water lines] to fit. Overall cost of all options is eventually about the same give or take a $100-200.

Well then i'd say it would be a better option buying an after market turbo rather then playing around with my standard one.

I still want to see your mods/figures...

I emailed them to you, along with the photo's etc all sized down etc.

there not, just means they need to be warmed up and cooled down, and oil needs to be kept clean.

ill just get Ed to do mine, it's going to cost me three grand but it will be stell ball bearing and abale to run 20psi or more

    • Hi...so a "development" here aswell The swap is "done" and car went "test drive" BUT it seems the clutch(maybe gearbox?) is a little bit sad? I bought this clutch kit https://justjap.com/products/xtreme-heavy-duty-organic-clutch-flywheel-kit-nissan-skyline-r31-r32-r33-push-type "Problem" is that the first gear is hard to put into and it seems that the clutch is not disengaged. It was not the problem with the old clutch...(or like sometime the first gear would not get as easy specialy when the fluid was cold) So? Can it be like...bad "install" or is the clutch wrong ((it should not have been) i done research to get the right one) Or is this "normal" with new clutch and needs to be break in? 
    • @Duncan I can try  and thanks i did not thought about VIN and part numbers for 33/34. @GTSBoy yeah it looks like iam gonna do that  
    • Forgot to include this but this is the mid section of my steering rack that looks like it has a thread/can be turned with that notch mentioned in the post:
    • Hey everyone, Wanted to pick some brains about this issue I'm having with rebuilding my 33 rack (PN is 49001-19U05). All of the tutorials/videos I've seen online are either R34 or S Chassis racks which seem to be pretty straightforward to disassemble but this process doesnt carry over to my rack. Few of the key differences that I've noted The pinion shaft on the other racks bolt on with 3 torx bolts: Whereas my rack bolts on with 2 allen head bolts: These changes are pretty inconsequential but the main difference is how you pull the actual rack out of the housing. The other skyline/s chassis racks can be taken out by tapping the rack out of the body with a socket and it just slides right out. I'm unable to do that with my rack because there's a hard stop at the end that doesn't let the seal/shaft be tapped out. Can also see a difference in the other end of the rack where mine has a notch that looks like you're able to use a big wrench to unthread 2 halves of the rack whereas the other racks are just kinda set in with a punch. My rack: Other racks: TLDR; Wanted to know if anyone has rebuilt this specific model of steering rack for the R33 and if there were any steps to getting it done easier or if I should just give this to a professional to get done. Sorry if this post is a bit messy, first one I've done.
    • I would just put EBC back on the "I would not use their stuff" pile and move on.
