That's a great idea dohmar. Our cars are very similar performance wise so I would definitely benefit from your developments. I see your car regularly as I work around the corner from boostworx so if you see a white crane on that street flag me down and we'll have a chat. I'll probably be more noticeable in the 32 though haha

oh you're part of the work thats being done on tha vacant patch of land behind thomas st? whats going on there anyhow?

I work for a company in technology park so I'm not far at all - my primary mechanic is road n track in thomas st, tho i use boostworx for troubleshooting and tuning of the gtr

-D

Naah I work at cross cranes on Thomas St. That vacant block is directly behind us. Housing I think. I would invite you to swing past sometime but the yard is secured by barbed wire and remote gates haha.

cross cranes? never seen em on thomas st? i know of cross keys paint n panel and road n track on thomas, and boostworx being the next st over...

Edit - looked on google maps, no wonder u see my car, its 3 doors down from ur work most of the time ;P

Yeah that's us. Stopped and had a good look at your car the other day. You need to fix your right skirt man! Other than that I like what I see ;)

the skirts and front bar are getting removed for painting, ive already got the clips from nissan to keep them attached properly

needs touch ups and a few mechanical things done but its getting there

-D

legality is put before performance in my case (sadly)

the 2860 series are certified as after factory replacements and can get thru regency with ease

thats the other bonus - what makes those other turbos more special than the 2860s or the hks equivalents?

And that is the dilemma. I've seen 2860-5 kits for $2k atm including the 14psi actuator, which means I can sell my N1's and actuator for around $1500 (which is what I paid and considering the car has been offroad for 6 months since I fit those n1's, they're barely run in.) The exhaust housings and sleeve bearings of n1's arent tops for performance, but they are legal. Just need to find someone who'd be happy with the close-to-300kw setup (i reckon they could get to 290kw with proper split dumps and front pipes), As it is, theyre doing 275 on a 21 yr old engine. 2860 -5 should be fine, unless the -7's are responsive enough. I just dont know.

-D

are u serious? tt application? I thought -5's were less laggy than the -7s ?

Maybe I should stick with the n1's.. they are so goddam awesome to plant the throttle and just hold on for dear life

-D

Ben, not sure where you're getting your info from bud.

Firstly, who told you that -5's are legal?

Just because they say Garrett, means nothing. You'll obviously need to run a PFC or similar to facilitate a tune which is an arse rape from Regency right there.

Secondly, -7's are more responsive than -5's due to -7's small Comp and smaller Inducer on the Turbine.........not 100% sure, but I think the -7's & N1 are similar in size so if you want something with a little more grunt (and slightly laggier) then go the -5's

Ben, not sure where you're getting your info from bud.

Firstly, who told you that -5's are legal?

Not just any garrets Pete.

Any 2860 series turbo, regardless of trim is legal according to the certification given out by MTQ and other turbo suppliers.

You're ignoring the nisstune I already have which tbh might be technically illegal, but if regency can find and call it, I would be very surprised.

Tbh the 2860 series nomenclature of their '-5 -7 -10' shits me off because its totally random. I havent done any research because I know u lads will set me upon the right path when the time comes. And that time won't come for at least 18 months. I have many other mods I need to do.

I just want a legal set of turbos that give me max power at minimal turbo lag and maximum response. Not aiming for figures at all, however the more the merrier as the saying goes...

The n1's are frigging great - but the exhaust turbine size holds them back, as does the sleeve bearing. Lets see what a set of street legal 2860's can do, regardless of trim!

Based on your sentiments towards the N1's, you won't be happy with the -7's........so as stated above, -5's are your next step.........-10's would be way too big for what you want.

-7's = similar to HKS GTSS

-10 = similar to HKS GTRS

-5 = somewhere in between the 2 even though the numbers are not uniform (blame Garrett)

Nisstune is not maybe a defect........it's def a defect if they come across it.

-5's are physically bigger than stock (not by much) so it depends how astute the Regency bloke is

Well, theres a certificate to make regency accept >any< 2860 series. Thats a fact.

Nisstune - well, they'd have to A) be suspicious of the ecu and B) find the modification which would involve disassembly of the ECU. Oh, and I also have an unmolested ECU just in case ;D

-5s are the shiznit it seems

however - i thought the 7s were a bigger turbo - more power, more lag? writeoff has the SS kit and hes doing 340kw or so but thats HKS and not garret

that said, in ur opinion, is HKS vs garrett a big deal?

-D

I did 348.5rwkW at Willall on their old Dyno Dynamics 2WD dyno & 335rwkW (after a tune) at Southern HiTech Dyno Dynamics 2WD dyno.

These charts may help:

the 33n1s in the first graph are what I have - steel turbine in the stock 33 gtr housing. aka N1's (compared to spec and what not).

No mention of difference in 2860 trims, esp in a parallel TT configuration - cant draw any conclusions

-D

Answer to 1st question

2860 being accepted or not is irrelevant as they would probably not pass EPO tests and furthermore, they are useless if you can't tune without a replacement ECU or piggyback, etc......which is def illegal.

Dale would be a better authority on this but I'm pretty sure they regularly remove passenger's side kick panels if they have any suspicion of tampering.

2nd question:

-7's def smaller than -5 as above comparison to HKS..............Garrett generally cheaper than HKS equivalent hence their popularity

If writeoff has 340 atw with SS turbos, I wanna see dyno graphs and what supporting mods he's got cause most guys on here only manage that with -5's

Thanks for that Dave

Ben, go to Garrett site and you'll find the info I've given you re order of size is correct

Dave's graph shows the -5 with a .6 Comp cover as opposed to your .42.........just one of the differences.......not to mention smaller Comp trim and smaller Inducer

If writeoff has 340 atw with SS turbos, I wanna see dyno graphs and what supporting mods he's got cause most guys on here only manage that with -5's

That sounds very close to calling me a liar Pete! :nyaanyaa:

All the info you want is in the Forced Induction stickied RB26 thread, a few pages in, CBF searching for it but it's there.

a) 2860's can be ran at stock gtr boost without controller and have same epa results due to the similar trim and AR ratio - camgears are more of a concern

b) you only need a tuned ecu when passing above stock boost so if u swap the ecu and remove the ebc then it all works as stock.

c) you've missed my point. have you ever seen a nisstune? my guess is no, because its a tiny little chip which fits inside the stock ecu. you could remove the kick panel and see a nissan ecu housing. But hey, PFC owners have been housing PFC's inside nissan housings for the last decade, so who am i to judge..

d) hks buy garrett turbos and do their own aftermarket bolloks (allegedly) which supposedly gives u +20 kw and + 20% the cost

e) Writeoff has an exhaust system that would make u cream ur gstring. Its unreal. He has the graphs, pm him direct for them.

-D

Not a liar bud, just like to see your specs which is what I asked for.............cbf looking either as I'm not that interested at this hour.

Reports almost done and heading off to bed.

I'll get him to send you pics of his dump pipes.

3 inches wide in what I believe they call 'lobster tail style' with full depth welds tucked close to the body pan

oh yeah, you best believe it. its the shiznit.

Ben, who is feeding you this rubbish............try running -5's (with or without stock boost) and see how they run without a tune....they def have different trim and comp size hence your AFR's will be all over the shop

You're requirement for a tune is based on AFR"S (in this case) not just boost.........I'm not even referring to boost

Cam gear adjusting will affect your valve timing.............a good tune will give you a nice balance between correct AFR's and ignition timing
