Wastegate size :confused:

LOL...i dunno. Whatever comes with the kit when you buy it. I think is a Trust Type R wastegate, and i think its 45mm...but im a long way from being sure:(

Dont get a TD06-20G, someone needs to do a HKS 2835 56T or a well sorted Garret equiv:)

You will be doing a phenomenal job to get that sort of power out of a 20G:thumbsup:

I thought about a T67 for a while, but looking at the exhaust wheel on them they obviously flow a lot more then the TD06 wheel and i dont think would be near as responsive on a std RB20:(

If my rb20det hadnt bit the dust, its nice to see what was capable of the old motor. I remember the time the most anyone seemed to say was capable of the little 2.0Lt was about 200rwkw...then times go by....220 then 240...now it seems you guys are tipping the scales getting close to the 300rwkw.

Keep it up i say, but i just cant stand the lag. When i want it the power down, i want it now..:P

A side not though, ive still got the rb20det turbo on my current setup. The turbo was highflowed and it recently made ~218rwkw @ 16psi for those out there wondering what the std turbo is capable of :P

The richness problem is due to the injectors im running they've told me hopefully another set of injectors will help that time will tell was gonna go the gtr injectors but they seem to think they will be a bit on the small side .Hopefully it 3will be back at the tuners in a week hopeing to get that extra 20kw im looking for :-)

Cheers Peter

PS yes am running 17" (255=40=17 ) dont know how you worked that out but im impressed

Approximate circumeference of tyre, rear diff ratio and 4th gear ratio means you can work out what revs equal what road speed:)

Aint perfect as tyres circumferences are all the sameeven though manufactureres claim 255/40/17...though i looked up the Dunlop site and they list all the specs for their D01J tyres:)

..also legend, did i read in another thread that you are running aftermarket cams....can you offer any comments on them?

Yes I am running cams Hks 264 9mm lift inlet and exhaust hks adjustable cam gears hks lowmount manifold hks to4 as well though its been high flowed now with a .63 exhaust housing and hks 35mm external waste gate custom 3" front pipe external waste gate plumbed back into exhaust just be 4 the catco cat .Cant offer any real comment as to the cams as yet but i know at the 232 kw his only played with the inlet so far he said that brought the power band down lower in the rev range but untill tuning is completedim not sure will post a dyno graph with a tune with cams at 0 you can see the differance though it could be more than just the cams as for comment it think id be jumping the gun just yet but it seemed to improve a bit of boost though unsure not enough driving it yet

Sorry for the bodgy overlay.

I thought it would be interestering to overlay Bl4ck32's RB30DET running a Rb20DET highflow and my Rb30DET running the stock rb20det turbo on stock boost.

Bl4ck32 ran out of load points on the pfc for that run, I believe it was actually 15psi he was running. Since fixing that issue up he is now running 218rwkw on 16psi I believe.

Its interestering to note how the bush t3/4 spools basically identical to the stock rb20det turbo once its on the larger 3ltr. :D

LoL, that is crazy hey. Whats going to happen when you guys put turbos more suited to the engine :D

Out of interest can anyone punch some figures on what a flowed rb20 turbo on an rb20 actually makes?

...hmmmm. Thats depressing. :D

Cubes if you cant sleep and feeling bored to no end then overlay those plots on mine:)

Has Darren got all his susp sorted yet? Get in his ear and get him down to AIR, he has about the same power as i had when i ran my 12.9. I would love to know how much quicker he will be with a car thats easier to get off the line and with a whole lot more mid range

Makes me think what a complete stock, not even rebuilt RB300E bottom end with RB25DE head could do with a 6,000rpm limit with my turbo setup...would set me back about $1200 and could always put the Rb20 back in if it dies, then start the RB30 build:)

LOL..i have to keep telling myself that im sellign the car:)

Here it is.. :D

Does 125km/h sound about right for 5000rpm on your dyno sheet Roy?

Since the tune Darren is now able to take it to just before 7000rpm and it pulls all the way there. I'd like to see the new dyno sheet at 218rwkw and more top end, but there isn't one.

If you ever get a broken manifold stud Roy and need to pull the turbo off we should do a quick swap, get shaun to give it a quick 1hr tune and see what it pulls. ;) hahaha if only it was that easy. :D

I still think your setup is awesome, not to forget RacePaces tuning :)

Ive got bilsteins in atm, but need a wheel alignmet, bushes/pinapples for the rear then get some better rubber...(looking at Toyo Proxes R888:drooling: ) Im curious to know a time as well, but shes all wheelspin for 2 or 3 gears in the dry atm...:D

alright some bitch ran into the back of me other day and im not happy... gotta get damage fixed and probably going to get a full respray as well :D

on tuning side im going to go back some time this week and pump 20psi through the ****er and see if i can get over 340rwhp (250rwkw)... will see how much timing its got in it and see how safe ant thinks the tune will be but i doubt ill ever run it with that much boost. probably stick with around 320 @ 18psi and try and run approx 115mph at the drags when i next get down there

will keep u updated

      Duncan's V37.......race car?

      By Duncan · Posted

      Once the airbag is off, to remove the steering wheel.... Undo the 2 plugs into the clock spring, and the horn connector from it's clip. Hit the 19mm nut with a rattle gun (preferably) or if you don't' have one, you probably want an assistant to hold the wheel in place while you use a breaker bar to undo the nut Then, screw the nut back on 3 turns, and pull the wheel sharply towards you. If that doesn't work hit it medium force with a rubber mallet on either side, or possible behind if you can get there. If that all fails (it shouldn't!) you might need a steering wheel puller

      Duncan's V37.......race car?

      By Duncan · Posted

      So, to next task....the carbon fibre steering wheel was either an expensive factory option or a chinesium special. Either way, I don't like either the flat bottom or thick ring style, so it had to go So...to remove the steering wheel.... First, disconnect battery negative and stop on the brake pedal for a few seconds. Then, remove the small circular covers on each side of the wheel's rear surround to uncover the airbag clips. You need to push something like a flat bladed screw driver through, you need to push the steel clip inwards and pull the side of the airbag forward. Once you've done the easy side, same on the centre console side. You can see the tab you are shooting for circled in red Then, disconnect the horn spade connector and for the yellow airbag plug you need to get something small under the black locking tab to pop it out, then the connector releases......airbag is off

      GReddy Injector Help!

      By Duncan · Posted

      Ultimately, if the tip is not far into the runner and the o-ring seals, then you are in business. Have you applied pressure to it as is? It is not really a problem for the injector to twist once it is bolted down, the oring seals it and you don't want it jambed into the oring too hard The plenum is intended to take multiple size lower injectors with different adapters, but the way you have it is fine if they seal.
