Hi all,

Is it ok to have HKS Cam gears with Tomei Pon Camshafts in an R34 GT-R??? Ie. doesnt have to be HKS cam gears with HKS camshafts and Tomei with Tomei etc?

This wouldnt effect the tuning process would it?

Also on a bit of a side note, would the Tomei Type B poncams (260 IN & EX, 9.15mm lift) be better suited to my car equiped with a pair of Garrett GT2860R-7's (with support mods) than the Type A which is 260 IN & 256 EX???

Better suited as in, more power in a wider power band?

Cheers,

there is not much difference between the type A or B set. you'll be happy with either.

and yes there is no problem with running different brand cams gears with the cams. though having said that I prefer the tomei gears to the HKS ones. but if you already have HKS ones I would just use them.

Hey man, jst wondering if you have had the car dyno'd before installation of the camshafts + gears as id like to know whether they are a worthwhile mod. Ive read conflicting reports about stock cams being better; are there noticible gains to be had for turbo's that small?

any1 care to share

cam gears are definitely worth doing. cheap to buy and fairly cheap to install and need 1 or 2 hours of set-up and you'll get good gains on stock or small turbos. up to 30kw mid range is possible and usually some decent top end gain too.

Thanks for the info guys.

Yeah no worries, i'll compare them and let you know how it all goes once I have fitted it all up and tuned it... might be a while tho... :(

nice nice, 30kw in the midrange would feel very meaty indeed.

Ok off to the traders section to buy now, should i do my timing belt while im at it?

thanks man, very nice choice in car btw :bunny:

yeah do the timing belt. in fact you can buy a brand new genuine timing belt off me! ;) I'm selling two spares ones cheap... :blink:

If you do your timing belt you may as well do the tensioners etc while your there, you can get away with slipping the stockers off the belt and slipping the replacement aftermarkets on

sounds good baron, ill pm you about it now.

jst quick what are tensioners? is a change required due to wear

Im quite excited about the cam gears as ive got my dyno run at 255awkw and would like to see the gains that are produced simply by adding them, ill be dialing them in for midrange.

tensioners and other bits etc are part of a 100,000km service, if you do change the belt you may as well do the full 100,000km service and get it done and over with

How much do tensioners roughly go 4 for an R34 GT-R?

if you do change the belt you may as well do the full 100,000km service and get it done and over with

So does that also mean:

Tensioner Bearing Spring

Timing Belt Idler Bearing

Cam Seal

Crank Seal

Water Pump

Thermostat....

aww ive only got 25k on my car so a long way till 100 lolz; might be paranoid and do it all 50k

    • Have a look at that (shitty) pic I posted. You can see AN -4 braided line coming to a -4 to 1/8 BSPT adapter, into a 1/8 BSPT T piece. The Haltech pressure sender is screwed into the long arm of the sender and factory sender (pre your pic) into the T side. You can also see the cable tie holding the whole contraption in place. Is it better than mounting the sender direct to your engine fitting......yes because it removes that vibration as the engine revs out 50 times every lap and that factory sender is pretty big. Is it necessary for you......well I've got no idea, I just don't like something important failing twice so over-engineer it to the moon!
    • Yup. You can get creative and make a sort of "bracket" with cable ties. Put 2 around the sender with a third passing underneath them strapped down against the sender. Then that third one is able to be passed through some hole at right angles to the orientation of the sender. Or some variation on the theme. Yes.... ummm, with caveats? I mean, the sender is BSP and you would likely have AN stuff on the hose, so yes, there would be the adapter you mention. But the block end will either be 1/8 NPT if that thread is still OK in there, or you can drill and tap it out to 1/4 BSP or NPT and use appropriate adapter there. As it stands, your mention of 1/8 BSPT male seems... wrong for the 1/8 NPT female it has to go into. The hose will be better, because even with the bush, the mass of the sender will be "hanging" off a hard threaded connection and will add some stress/strain to that. It might fail in the future. The hose eliminates almost all such risk - but adds in several more threaded connections to leak from! It really should be tapered, but it looks very long in that photo with no taper visible. If you have it in hand you should be able to see if it tapered or not. There technically is no possibility of a mechanical seal with a parallel male in a parallel female, so it is hard to believe that it is parallel male, but weirder things have happened. Maybe it's meant to seat on some surface when screwed in on the original installation? Anyway, at that thread size, parallel in parallel, with tape and goop, will seal just fine.
    • How do you propose I cable tie this: To something securely? Is it really just a case of finding a couple of holes and ziptying it there so it never goes flying or starts dangling around, more or less? Then run a 1/8 BSP Female to [hose adapter of choice?/AN?] and then the opposing fitting at the bush-into-oil-block end? being the hose-into-realistically likely a 1/8 BSPT male) Is this going to provide any real benefit over using a stainless/steel 1/4 to 1/8 BSPT reducing bush? I am making the assumption the OEM sender is BSPT not BSPP/BSP
    • I fashioned a ramp out of a couple of pieces of 140x35 lumber, to get the bumper up slightly, and then one of these is what I use
    • I wouldn't worry about dissimilar metal corrosion, should you just buy/make a steel replacement. There will be thread tape and sealant compound between the metals. The few little spots where they touch each other will be deep inside the joint, unable to get wet. And the alloy block is much much larger than a small steel fitting, so there is plenty of "sacrificial" capacity there. Any bush you put in there will be dissimilar anyway. Either steel or brass. Maybe stainless. All of them are different to the other parts in the chain. But what I said above still applies.
