BOOSTD

It may have been, comp was 8.7 which shouldn't change the lag as much as it did. I also had quite extensive porting

Engine/Car: Rb25 Type of failure: Ringlan Factors influencing the failure: Pre ignition, to much timing State of tune of the engine:250rwkw, std injectors Oil used and service interval: Motul every 5000km General comments: Own fault Engine/Car:R33 GTR Rb26 Type of failure: Ring lans Factors influencing the failure: don't know State of tune of the engine: GT2530's std everything else Suspension and tyres:std Oil used and service interval: don't know General comments: Bought car with blown motor, most likely popped from to much boost and no supporting tune. Engine/Car:R33 GTR RB26 Type of failure: Gugeon pins out the side Factors influencing the failure: engine builder incompetence. Press fitted pins instead of floating State of tune of the engine:300rwkw Oil used and service interval: Motul 300v General comments:engine was 350km's old, oil temps went through the roof and lots of smoke. Engine/Car: R33GTR RB27 Type of failure: 24 bent valves Factors influencing the failure: snapped idler pulley belt. Greddy timing belts shrink when hot State of tune of the engine: 360rwkw Oil used and service interval: Motul Le mans 24hr General comments: travelling at 10kmph engine lights came on, pulled over and cranked motor with oil cap off to watch the cams.......bugger lesson: Don't get an engine built by StM@$y's Engines. Tighten Heavy duty timing belts slightly less and renew the idler pully bolt with the timing belt....do not over tighten.

I modified the squish zones on my Rb25, I found it reduced exhaust port velocity and increased lag. I did not however run pistons to suit.

trade with 33 Gtr rims?

western clutch in syd will reco the clutch for $130. Machined and new pucks

Advan didn't build it, I did. I also tuned it. The horse power calc for my weight (1620kg) at 120Mph came to 355kw and that was on higher boost. so ADVAN's dyno may actually be alittle happy. Peter mentioned the other day that it had been re-calibrated and now reads lower.

did you guys notice the music track that played at the end....didn't really fit with the theme since it was in Italian. bit like a motec system exhaust

were can I get a Greddy stamp.....

I'll take it if it is still avail, I am also in western Syd

ECCS relay output most likely no going to earth. This is from a fried chip. Can be fixed. i have fixed a few. do a search heaps of info on how to repair. Pin 40 on my GTR PFC ECU. Anywho that out put should earth when the ign is on.

I run these cams also, can't speak more highly of them. There aren't many upgrades that give an improvement EVERYWHERE in the rpm band. But these will !

I'll take it, pm me pickup details blitz

I am also running HKS 2530's. My engine also has: 260 9.15 Poncams 88mm pistons SS manifolds ARC twin entry intercooler twin 3" exhuast merging through collector to 3.5" at the rear seats. (2x4" magic Cats) It made 360rwkw @12.5 psi on ADVAN's dyno ( later found my exhuast cam gear had slipped...car felt very laggy but huge top end.) I recently ran a 11.5 @120Mph on BP98 and 16psi boost and no-name street tyres (1.9 60') Turbo response is very near stock. My datalogger shows AFR's were around 11.6-11.7 up to 6500rpm then into the 10's.

hmmmn definately faster than Nengun, they took 2 months for my Poncams

what offset are they?

they work with Series 1 and 2, as do the std ecu's

Most people don't have any issue's unless chasing big power. ie 300rwkw+ Bar and Plate cores do tend to cause a large flow restriction however.

I'm running the chinese SS manifolds. Car made 360rwkw at 12 psi with GT2530's and ran the time below on 16psi... quite happy with them

I also ran a turn flow on my GTST. made 218rwkw with the stock turbo....It's definately not restrictive. The core is were the majority of restriction is and you are looking in the right spot. =)

http://www.arcinter.co.jp/arc/products/ic/ic2.html Its the core design that makes all the difference. note the flared tubes on the inlet side of the core. On any other cooler the air hits 50% or more of a brick wall. ARC reduce this restriction to a minimun. It is also worth noting that I previously had over heating problems which are no existant now. Flow through the core is also improved.

this is mine

I recently removed my TRUST cooler for a ARC twin entry. The difference is undescribable.....Its a different car ! more mid range ...helll more power absolutely everywere. The low restriction type tubes on the inlet side (where they flare out) make the would of difference. I WILL never buy TRUST again.

Price for the IVA-D300 pls
