the "taperd #3" stud is only neccisary for 11mm stud kits right? not 10mm?

I deleted the pics that were to big, don't post up pics that make the page require a friggin 4 way scroll wheel just to naviigate.

Its not actually tapered... its undercut. And yes... only on the 11mm studs. This allows the oil to move from the block to the head with no restrictions.

Sorry mang, I thought it was resized when I posted it. Oh well.

[WDRacing]

No worries, no big deal at all...Just imagine the poor bastards with dial-up still...lol.

whats the trims and A/R on robs 67?

[ROB240]

.70 a/r s cover, .69 a/r p-trim

[DET_Monster]

is that trim and A/R best suited to KA? whats your expected spoolup?

[HolyShiznit]

It will spool just fine when the nitrous hits. My suggestion, do what Rob and the other guys did and research. Read up SVT Performance, LS1Tech, SupraForums, all those places, find out what the big boys do and apply their tech with ours. Rob found out his correct trim and shizzle by RESEARCHING, especially the supra guys. That's what me and Rob both did. Read the supra forums for big turbo tech and read LS1tech for nitrous info.

BTW: DO NOT EXPECT to spool that bad boy without nitrous. When playing in this field you don't "expect" spool up by a certain time, it's just spray and then it will spool.

[ROB240]

or two step off the line

[DET_Monster]

ya, I know I need to figure things out on my own, I dont know the math to calculate, but I will read on the things you stated and see what I can come up with. besides off the line though, say from a roll, I wondered approx. rpm that big a slug would start building boost. thanks for the response and good luck with your projects

[DET_Monster]

I want to be able to spec my own setup, but besides compressor maps, i dont know where to start? I looked at a pt67 GTQ on a sr20 (dont flame me), and assumed it would spool faster on the KA simply due to more displacement, but i know there are many factors that play into that (head, cam, manifold design, etc). where can I teach myself how to determine what trim and A/R are suited to the KA besides just lookin at others setups? sorry if i sound like a noob jack***, but I want to learn. thanks

[ROB240]

from a roll? brake boost honestly though, there isnt a real mathematical formula you can use to see when a turbo will hit a certain psi on a given car, the easyest thing to do is to compare the results that other people have gotten with there cars in reference to turbos commonly used on our cars. Or see what different variations of the same turbo yield on other peoples cars, such as switching to a larger exhaust housing, or swapping turbos all on the same car. A lot of the supra guys do this and post before/after dyno results so you can see what the change was. Just keep looking, the information is out there, ya just gotta find it (which is sometimes easyer said than done).

[DET_Monster]

thanks Rob, one more thing, say i find info on a particular turbo on supra forums. how do i compare numbers between a 3.0L 6cyl, to 2.4L or whatever the situation is? or is it a guessing game?

[HolyShiznit]

Well if a turbo on a Supra hits 15 psi by 4500 on their motors then think about it hitting 15 psi by 5grand+ (at least) on our motors. But also remember that off the line you should be using either nitrous or two-step and from a roll you will still want to use nitrous to spool it. IMO. It really is a guessing game. You can also look and see what some of the SR guys do and just guestimate off that.

[DET_Monster]

thanks, I will continue research, you will know when I'm done

[klattr1]

whats the car gonna be used for?

[DET_Monster]

honestly, a street sleeper, fun car, weekend track (drag of course)there are a few mild turbo mustangs and a 600whp integra that i would love to give some nissan competition to but trying to figure out if thats possible.

[klattr1]

sure, with the right amount of money for the right parts. just keep researching though, you'll find what you are looking for.

[DET_Monster]

like the pt67 .68 a/r ptrim, spools good on supras, might work well on KA with valvetrain.

Duy has a PT67 with .68 backside. He gets full 30 psi of boost around 5000 rpms (stock intake manifold, s13 cams, supertech springs/retainers) and revs to about 7800-8000 rpms.

[DET_Monster]

thats what i wanted to know! thanks, lookin at something now that might work out well

[WDRacing]

I always wonder why no one uses a smaller turbo and just more N20 for the track. Big turbo's suck for daily driving, I've been there done that with my Skyline. Pulls your teeth out on boost, but off boost simply sucks.

Why not just use the bottle at the track?

[DET_Monster]

i know its irrelavent for track, but i like how the big turbos can do serious hp on pump. Just doing something different for me

Ok two things here, first, if you are gonna go try to run with the big boys and use pump gas then quit now. Your big numbers, big boost, big turbo is gonna need something more than 92 octane. Otherwise my small turbo is gonna eat you alive. The main difference being the tuning. You will have to limit yourself so much by restricting power production to a pump gas diet. Don't FALL INTO THE HYPE. Who cares if you can make 400-500whp on pump gas, you could probably make 500-600 on higher octane with the SAME EQUIPMENT. Not to mention the fact that if you are gonna use that PT67 + nitrous with pump gas then....well that's your motor dude.

As for WD's comment: *points to my car* I will get you pics of my nitrous kit. 24 psi by 3900 + a 50 wet shot should be a good kick in the pants.

This is one crazy thread btw....

[DET_Monster]

not worried about power on pump, just a side benefit is all i meant. boost plus n2o plus pump gas equals explosion

K, I was just making sure, I figured you knew what's up.

[DET_Monster]

thanks for the help guys!

[JDMEnthused]

very nice... i love KA-T's.. we just need a bit more aftermarket support, maybe and we would be set.

or not? the fastest KA-T runs a 10.9 in the quarter and thats only with 600hp horsepower.. pretty damn good if you ask me, thats with a S14 though.

Duy's old S14 ran a 10.8 at 132 as well. also there was a backhalfed S13 KA-T running 10.3's a few years ago.
