Don't worry about the big ends... Unless you want big power (300rwkw plus), the stock ones will handle the job fine... Just make sure there's plenty of oil pressure - and don't use a shit oil.

As far as rod bolts go - Tomei are the best mob to get em off... Unfortunately all of ARP's stuff is in imperial measurements, and you'll want metric :)

Put in some nismo big end bearings, and some arp bolts while your in there...and if you really wanna load on the power, get the block o-ring as well....hell, even do the conrods while your in there....

Pistons might not be the first thing to go flying while ya turn up the boost mate... if ya wanna account for one thing, be prepared for something else to happen

oh - btw inasnt - my car's got forgies in it... They were cosworth blanks & were HPC'd to boot. The rods are RB30 stockies that were shot peened, nitrided and all the rest of it...

It really comes down to what you want to use your car for... if it's just going to be a quick streeter, get a metal head gasket to lower the compression some, stick some cams in it, and stick a T04e/GT3040/T60/(insert turbo of choice) and you'll get 250 on pump gas without any problems. Spend your money on a decent radiator and oil cooler. Cool inlet temps and cool oil and you shouldn't have any dramas. Run it with a powerfc and as soon as you see knock, take your foot off the throttle and you'll be right.

Only reason I did my motor is because I wanted to have some fun at the track.

FYI - Stay away from trust/mitsubishi turbos... They're rubbish. Only after I had mine rebuilt was it any good.

Can you give us a bit more info on this..thanks.

I hate to say anything bad about any product... but since this is such a contentious issue and this guy is not the first the re-iterate this point...

Do a search for "Trust" in this forum. See what you get.

While other people complain about HKS turbo pricing, they rarely complain about build and design.

The disclaimer is that many people use Trust and are happy but that mustn't blind one to the people who have problems.

T.

Well - any of the TD series turbo's have piss poor thrust bearings which will give the minute you start flowing serious power through them... Mine let go at 14psi (on a trust TD07S). I've heard of other people having similar problems, and it was only after I had the bearing modified that it was reliable.

Secondly, as far as drivability goes, they don't know how to match compressor/exhaust housing or wheels. I've seen a T78 on a GTR make boost 1000rpm later than a Garrett equivalent of a T88 (a much larger turbo). A similar garrett turbo on my motor would make boost 1000rpm earlier.

If you look at how they balance a compressor wheel on a turbo, they just cut chunks out of the side of the wheel, rather than garretts practice of skimming metal of the back of the wheel. Dodgy...

Hence my post - trust turbo's are rubbish.

No worrys :D The turbo in it now is a Hybrid T66 thingo... It's got a HKS T04-R front wheel, with a back cut t66 rear wheel.

Re: calder - I just came back from heathcote... Ran it up in full street trim and i'm very happy with the results :)

and the results were.......???

12.38 @ 123.45mph... That was run on my azenis st115's (not semi comps)...

60ft time was a shocking 2.35sec, and I couldn't stick the boot in till after I'd got into 3rd either :(

I had a set of nitto's to run on, but turns out the rims they were put on didn't fit under the back of my car, so I had to run in full street trim...

With those nitto's on the back I think I would have quite easily done a 11.6ish pass at 125-126mph... Oh well, there's always next time :P

matt

Cheers mate, I'm stoked with the times... I just wish those nitto's had have fitted... Although I guess it's still nice to have a time in my bag which is "full street trim"...

My final run for the night was going to be the quickest, but on the change into 4th the clutch decided to give up, so I had to pull out early... With a new clutch, and those nitto's, hopefully I'll see 11's on the next outing!

First run was a 13.1 @ 119mph, and all the rest were high 12's @ 121-123mph.

BTW - I can't praise the guys at heathcote enough! They even offered to help me fit the nitto's onto my normal rims to get me going - if anyone's keen on dragging - that's the place to go.

perhaps SAU should organise a drag event there?

matt

Yeah this is true - One of our guys had a clutch breakage, and as such had to get a tow truck home @ $250...

I had a trailer organised but it fell through (the car I'd organised to tow with only had a 1600kg limit didn't expect the trailer to be 500kg), so I was pretty much just hoping that nothing broke.

The thing is, you just have to go out there being positive, and if something bad does happen, worry about it then.

I had 7 or 8 runs on the night, and some of the other cars there had 10-14 runs. I had to pull out early because of the failing clutch, so you'd get plenty more chances to run than you would at calder that's for sure!

    • Ahhh, I need the whole head unit. I definitely needed to roll back through and review your setup, ha ha! Neat setup they have going on. I just need a full double din head unit. But I want good and responsive. I might have to review what the likes of pioneer have out these days.
    • Ok so after much research and talking with knowledgeable people I've got my turbo conversion done and it's all running great other than 1 small issue.  Car has remained auto with the na auto and tcm, I've used a stagea ecu with. NIstune board and everything is great other than my gear selection on the dash. It illuminates park, reverse, neutral, 3rd and 2nd. But nothing drive or what gear your in when you pop it into tiptronic.  I'm sure there is may e 1 wire in the ecu plug I need to move to rectify this. Dose anyone here have any ideas?   Cheers guys
    • Sorry I haven't been following all the detail, so you may have tried this. Does it idle with the tiniest bit of throttle you can add? You've mentioned the IACV, does it have an AAC valve and have you adjusted it at all (ie, screw the idle adjust screw all the way in, then back it out a couple of turns until idle is stable)?
    • My bad, I unplugged the one underlined in red instead of yellow before. With the car started, after unplugging the IACV (the one underlined in yellow), it idled at around 400/500 for 3 seconds before stalling. Attempting to start the car without the IACV will not start the car.   It does stutter and sputter for around 5 seconds before dying. However, immediately after starting it, you can already hear some slight sputters from the exhaust.   It won't start with the AFM unplugged. If it is when the car has already started, it stalls in a few seconds.   Yesterday, I did take some logs using Nistune of 3 scenarios. Car idling till it stalls Car idling and unplugging the IACV Car idling and removing the AFM I also have some previous logs of when the Car is idling till it stalls and when driving and it cuts. I am not really knowledgeable enough to understand what to look for. After every test, car idles rougher and rougher, until I have to stop. It will be fine the day after.
    • There is no difference between a 17x8 and an 18x8. The total diameter of the tyre needs to remain +/- the same (so you don't mess up the gearing, speedo reading, and clearance when turning front wheels..... so you just need to use a lower profile tyre on th 18 than you do on the 17. /rocket surgery.
