Changing the Cams should give you more low down power. A lightened Flywheel will let it rev quicker which should get it into boost quicker. Im running a lightened flywheel and i think there is a big difference. My mates R32 doesnt react as quick when taking off and the revs go up so much quicker on the run.

try cam gears.. worked well for me, basically shifted my whole power curve left :(

otherwise, the usual exhaust mods should help

oh, and throw in some more base timing

:(

What cams?? They brought boost on earlier im guessing by ur comment?

Thats what im looking for, not somethin to give me heaps more top end but abit more low down.

Otherwise i may just chuck the rb20 n go rb25 coz its such a pig off boost hahahaha

Waz, for some reason I thought u were running gtr cams?

i am, but i also run adjustable cam gears

but i don't think the cams contribute to off boost performance, more the cam gears that adjust the cam position...

which was what i was trying to say...

How much money are you willing to spend? At the end of the day the little RB20 will never be a great off boost performer. Cam gears, and tune may give you a little bit more in the mid, say 5kws??? But at what price.

Throw on a baby steel wheel turbo, run 15psi and run the ECU, fuel pup and bolt ons needed. By this time you have spent well in excess of 6k...and you will still have nothing off boost. Its a 1350 (driver, fuel etc) car with a little low compression 2L....sadly you can thave everything :P

      Uncle Duncan Yeap, FI Interchiller  Works well, normal IAT's cruising with the WTA only went from 50°c+ to 25-30°c with the interchiller  Before, when on it hard, the IAT would see 80-90°c, now, the highest has been was around 38°c IIRC IAT is measured under the blower hat I recommend it for the street or strip where your only on it hard for 10 or so seconds, but it wouldn't be efficient for sustained track use as it would heat soak from the AC turning off or whatever it does during WOT to protect the compressor It really needs the AC running for it to not heat soak and keep the WTA coolant chilled My WTA coolant temps when just cruising is around 2°c

      Hey Mark...sorry to interrupt your career change to hair dressing... but...did you ever fit the interchiller to the commodore, and if so how was it? And, who made it?

      I've been pondering this, I really enjoy the convertible thing, for me, it's like riding a motorbike, without all the issue of riding a motorbike, mainly, my old sore arthritic joints getting beaten up, and, being able to do it in shorts and a T-shirt and not needing a helmet and all the other gear required, especially like wearing jackets and pants in the summer, or needing 6 layers of cloths in the winter, or not having wet weather gear handy when your 100km away from home on the bike when it decides to start raining As for the hard top and its Coupe look, whilst I do lose all that open top feeling that I really enjoy, from my experience with the NB with a detachable hard top, the cabin is a much nicer place to be, the difference in noise for one, a hard top quietens down the interior, alot, with the soft top up or down it's pretty noisy, which, after 5 or so hours, can get tiring But, as you stated, the detachable hard top totally changes the look of the car, in a really good way, and for me, the look of a detachable hard top is so much better than the PRHT which looks more like a after thought with its weird bulbous rear roof line For me, the minimal effort of putting in on, or storing it after removing it, is well worth the time and effort for the look alone And yes, I'm sure the next owner will be grateful for it as well.......
