Gtr T618z Kit ... Go-no Go?

[XRATED]

I'm upgrading from T517Z 10cm's. I made 399.6rwkw with the T517Z's on a bone stock(internally) 26 on 98.

I like my trust intake, charge and dump pipe kits and I want to stay with low mounts.

Car will be used for everything! Drag(pb 10.6@138), open circut and lots of street duties.

Has anyone made numbers with the T618Z kit?

Dyno sheets?

On road driving experience?

From first hand experience, how do they compare to HKS GTR'S?

Cheers

you have gotta be shitting me, those marketing flamin mongrels have never done the job themselves

how much more power do you want? and how much more do you reckon the stock motor will take on 98RON with old factory internals?

I mean if you can't squeeze any more out of the 517s and you need more power then the 618s are the logical choice really as like you say you can keep all your current intake and exhaust gear.

Im with Richard in all regards

May the stock RB26 RIP... or rather it soon will.

Ive done a few sets of T618Z's and usually against my recomendations, the engine work required to make them work is extensive... but for your application they might fit the bill.

The T618z's are designed for drag and circuit use and i have personally been in a GTR with the 618's on a well setup TRUST car and it was awesome (700+ps @ 1.8bar), i supplied TRUST's receipe to a shop out sunbury way, including all the parts about 4-5 years ago but due to reasons i cant post it never performed.... shame as it was a waste and had heaps of potential.

Big cams, port work, big boost (they are rated 1.5 - 1.9bar) and rpm are needed to make them work, a nice white street / ciruit GTR here in melb (creatd built) has run low to mid 10's with a custom pair of garrets built by rotomaster to T618z specs... again with a built motor to suit... expect to turn your motor inside out.

HAHA i supplied the information for that flyer years ago....when i was doing the buying for their stores (TRUST / BLITZ / APEXI etc) I DID NOT supply the fit times though ..... i think if you look at the Td06-l2 kit flyer for SR20 they just stole it from that

some of the said receipe is included in that flyer.

hahaha gold, thats pritty much spot on too, thought never crossed my mind

Thanks for the input thus far guys.

I should have stated that a built motor is on the way.

AND on that note, has anyone tried sleveing a stock block with good results???? I want to keep the origional block and head in the car if I can, but I know it willl split at 500rwkw at 2 bar + .

That's a super, metabolic, fuel particle, atomatizer device to keep the molicule chains in a row and the fuel atonomous.

Fuel filter..

That's Rear load bearing sphynter valve..

fixed... well at least thats what apprentices should be told..

I think you meant to say... "expect to turn your wallet inside out".

I upgraded my T517z to a T618Z a while back.

I lost a bit of bottom end and gained a lot more at top end as expected.

It's on a 3L so it's not laggy at all.

I would love to know how these compare to the HKS GTRS though.

When do you start making usable boost with the 3lt? What was the diffrence in respose roughly? 300-500 rpm???

Don't suppose you have a dyno sheet?

520 wkw is an awfull lot for 700cc injectors... hmmm.

I had to sleeve a block a while back to keep standard size bores....I can't imagine any other reason you would do it though. the standard block, properly prepped, will make to 500+ you are talking about
