I have an SR20 with gt3540R with .82 rear makes 1 bar about 4600 obviously this not an rb30 but with 2 more cyclinders and 1 litre more then my sr20 you would expect it to spool 1 bar a good 1000 rpm earlier.

Do it simon you know you want to !!!

mmm, thats interesting. Any chance of getting boost on there too ?

Autobarn acutally have access to them Although I think there stupid $$$$$$$$$$ +++++ $$$$$$$ Seen them on there in store computer catalog.

I'd be intersted to know if anyone has wired a consult plug into a loom. I could see this being useful for conversions were the newer engine in and older car loose's out. I have found this on the net previously. Not sure how accurate it is. Has anyone also had success downloading an ECU Rom file(bin) using the consult ?? I have tried it using nissandatascan on R32's and it seems to sit there and do nothing.

I'll point out what i see as an issue with this idea. he is adjusting the AFM reading accross everything. It is not dependant on RPM / Load / Temp / Conditions. Sure he is testing on the dyno I assume full power runs at full throttle. I would say he could get that quite right. I doubt he tested all rpm / load conditions at all temps. If he leans it out with this method, everything is leaner !! Things like close loop driving will be leaner. Light throtle leaner. Cold start leaner etc etc .... Sure he can leave a "buffer" but as you can imagine it would not be an ideal way to do things.

can i point out that its a bit hard to call how laggy a turbo is without seeing the tune ? Your assuming that all other factors are perfect. if your timing is way out(cam belt slipped) for example it can be a pig to spool and make no power.

Brazilian http://www.masterpower.com.br/ They seem ok from what i have "seen". Personally with the price of garret plain bearing turbo's unless you are getting the master power REALLY cheap then why would u go past a proven Garret.

One thing that bugs me is from what i have seen midly modified rb20's make peak hp bewteen 6200 - 6800 rpm. Engines without cams this is. Then pretty much the power dies of. So really not sure why people swing the rb20 beyond 7k in these states of mods.

1.6 60ft !! Damn !! I assume thats slicks ?

SK, Is it not also possible with a new fuel pump if its running a "LOT" more pressure and flow, for it to actually push more then the fuel regulator can handle ? Then creating greater rail pressure and a richer tune ? extreme case probably but curious.

Amm there is also the breather into the inlet snorkle. Which fills all your piping and intercooler with oil. I'd say using a catch can to stop that isn't rice.

I believe the main issue you will have is with the final rear hook and the tip alignment under the rear bumper. They are not the same exahust.

I see Fatz you have your D-jetro for sale now. There are a couple of 26's here(perth) now running d-jetro without the single throttle body conversion. Perhaps it would be worth your while speaking to X-speed in perth.

There is a difference. I have pulled the rom files of both a silvier Rb20 auto and a manual. The main tables(fuel/ignition) are pretty much the same. The rev limit seems higher on the manual though(although this could be a fluke). The actual map files are not the same though. From what I understand the auto softens the timing in the higher RPM so when you stand on it, during the gear change there is not as much tourqe. Hence going from an auto to manual, a auto ecu would work ok, you just may find the top of your rpm lacking slightly. If you were to go the other way, manual ecu in an auto, you will find your gearchanges some what un-pleasant with the auto box at full throttle.

Ok. Pics up http://users.tpg.com.au/butters9/Cams/Apexi.JPG http://users.tpg.com.au/butters9/Cams/Cams1.JPG http://users.tpg.com.au/butters9/Cams/CamsNSprings1.JPG

Got this nice set for sale Apexi 260 intake and exhaust Cam shaft 10.8mm lift Matching Heavy Duty valve springs All to suit SR20det Red top. The cams were sold to me as 260(although i can't verify thats what they are) I have confirmed the lift is 10.8 though. On my SR20 they gave a good 25 - 30 rwhp increase across the rev range with no other mods and at the same boost level. These are used but in excellent condition. Will post up pics at a later date. Looking for $850 for the set.

Your base timing might be right and you may pull out heaps of timing in the ecu ... doesn't mean your cam timing is correct ... Any chance you got the teeth out when you setup the timing belt ? Just a thought

Ammm AFAIK, There basically the same turbo dude. The GTRS was released later and has basically the same wheels as the GT2835. The only difference was the GTRS has a smaller compressor cover. Designed to be used as a direct easy replacement to a lot of nissan turbo's. That said the gt2835 should net more power based on the larger cover. Neither will make 350rkw. Ther are rated at 400 ps(give or take depending on models). So about 250rwkw is realistic.

Hey All, Going to be in Darwin again for a week soon. Wondering if there is any drag / car / any car events happening ?? How is the import scene in Darwin doing ? Simmo

Thanks red drifter. Already had a good look around there with no luck. Plenty of manual ones on there. I assume Darkhalf is on here ?

Hey all, From what I understand there is some minor difference's with the R32 auto vs manual rom files. I am in need of a R32 RB20det Auto Bin file asap. Gimmie a yell if you have one handy. Simmo

Depending where you look, it varies between 20 hp difference and 100 hp. I did find an 80 hp variance in one place. Gotta love acurate net info ... Everyone seems to rate the 1.06 rear one as 700hp. The .86 rear seems to vary between 620hp and 680hp ...... actaully just found a site that rates the .86 rear as 700 hp too Be really nice to know exactly what the .86 rear one is rated at if anyone knows for sure ?? The Garret Catalog rates the .82 and 1.06 from 400 - 600 hp ....
