Ya he is a member here, and how can you not be impressed he beat a damn viper!!!! That is surely enough to impress the hell outta me.

Hey trueslide, you should just open up a chatroom, if you want to discuss KA turbo, i'd be more then up for it. Besides i'm not going anywhere for awhile.

He runs 26lbs of boost, although i'm not real impressed with his hp numbers. I think his turbine is really restricted him. Anyhow, there was a cool video posted a while back of him racing, and beating a viper. He takes it by about two car lengths. Its tight.

How are you not impressed with nearly 400 whp and over 400 lb-ft at the ground?

Already a 240sx chat room

its IRC Efnet servers#240sx

Post by **kansaidrift** » Fri Dec 13, 2002 4:27 pm

I'll try to find the chatroom. Ok, let me modify my previous statement. PSI240sx is damn fast. However i think his wheel hp is suffering do to his turbine size. I think on his website he posts hp at in the high 300's. But yes, beating a viper that costs three times as much as his car is impressive.

His torque is what's impressive. That, and how the car looks stock on the outside and can get sideways through the top of 3rd gear with autoX tires on.

Just a qeustion, how the hell does he ever grab traction with a set of 225's on the rear. Last i looked thats what he's running right? Anyhow, i talked to a buddy of his and he said he wanted to upgrade the tire size, but was concerned that even with a wider tire patch, the lower profile sidewalls would be to stiff to give good straight line traction. Oh, and how do i get to this chatroom trueslide is talking about, i seem to be having a time with it?

I don't know what size he's running right now. But anyway, the car is for sale.

Post by **kansaidrift** » Fri Dec 13, 2002 4:27 pm

Thats awesome, where's it for sale at? On ebay or does he just have the word out? Oh, and how much is he asking? Yep, and one last qeustion, i still can't find the damn chatroom. Ahhhhhhhhhhhhhhhhhhh to be computer literate, what i wouldn't give.

YouTube · Post by **EZcheese15** » Fri Dec 13, 2002 4:27 pm

I think it's just word. But I believe he was asking $15k for it. He made a post for it in the buy/sell/trade forum on this site a while back.

Here, I looked back for his post, and here it is:

It says "make offer" so I don't know what he would take for it. I would guess around $15k though, but you'd have to ask him.

Post by **LarryStooge** » Fri Dec 13, 2002 4:27 pm

whats the link to his site? I keep getting "page cannot be displayed" when i try to go to it through his profile.

Just a silly question, WD, you mentioned that you wanted this beast streetable, what about practical? Methanol? While I respect your overall goal, I have to wonder What's the point. Everyone has been giving a lot of ways to gain power, but to what end? Are you looking to enter IHRA? Unless you're going for <9's, I don't see a purpose in going that route. And if you are aiming for <9, streetable isn't really an option anymore.

Post by **WDRacing** » Fri Dec 13, 2002 4:27 pm

Actually methonal/alcohol is probably one of the best things I've ever installed on any of my cars. With the Alky injection on my car I added 83 rwhp. The alky allowed me to up the boost 9.5 psi with no knock indicated netting the additional hp while keeping a 12.2/1 A/F curve.

The alky/methonal is not on all the time. Only under high boost conditions. When I run low boost(street driven) the meth/alky will not be engaged. I've been using alky for the last 3 years. The Buick Boys have been using it for atleast 10. I can't think of a better way to run high boost safely.

As far as rods and stroke go, I'm going to maintain factory specs. I'm quite sure that with crank and valve train work I'll be able to rev towards 8000. I also have a ton of experience with vibration analysis. Not to mention access to all the equipment for free. So I'll know what will work and what won't prior to anything exploding.

If I use N20 with the setup I've planned then 650 will be easily attainable. What I would like to do is get there without N20. I might have to use a small squirt untill boost builds but I can accept that.

The main reason I want to build this engine is for the rarity. Everyone does thr SR swap, soon everyone will have an RB. But you don't see insane KADET's rolling around. Plus I've always rooted for the underdog and I need a good project when I get home.

PS...lets try to keep on subject here fella's...use the PM if you want to talk about other things.

What about cams? Are you planning to go with a more aggressive lobe profile? In trying to keep it street driven I would imagine you may have an issue with idle. As your valve overlap increases, you tend to lope.

Post by **WDRacing** » Fri Dec 13, 2002 4:27 pm

I'll be running custom cams. Not sure about the lift yet but somwhere around the 272 mark for duration. Both in/ex being the same or very similer.

Cams is one aspect of the KA that people very rarly talk about online. I've looked all over the place only to come up disappointed. Not many peole run alot of duration on there KA's. I'd like to hear more about this. I'd have to say most of my cars have run cam combo's that had already been tried. This will be a first for me.

Cams are not a very popular mod. I think it has a lot to do with the fact that it's not very glamorous(sic?) but I'd recommend a longer than stock duration, but don't go overboard. Look into Crower and Gude. Crane and JWT also have cam swaps for the KA, but I've heard JWT's overlap is a bit too long. I haven't had any firsthand experience with Crane or JWT, but they're both reputable companies. Hope that helps, but if not, I do have George's email if you want to ask him....

They sell custom cams made by COLT. Could be worth checking out and Iam sure if none of them make a cam that doesn't fit your specs, they will probley be more then happy to custom make em.

Post by **I am Technoman** » Fri Dec 13, 2002 4:27 pm

I use the Nissmo cams on a n/a Ka24de and I got 12 RWH.I think these cams would pull more like 20hp with a turbo...248 degree 390 duration both sides..

Post by **240racer** » Fri Dec 13, 2002 4:27 pm

I haven't gotten to the point where I need to replace my cams, but what I hear from my friends that have high boost supras is that you want long duration, with less overlap. This prevents some of the charge air from going out the exhaust valves. I'm not saying I think it's the way to go, just a thought to consider.

Also, as far as longer rods go, you want them as short as possible and here's why. They are a pinned beam in compression that's only fear is buckling and short and fatter is better. Also, they are in tension too, but length doesn't matter there, just having minimal stress risers.

If you are running towards 8000 rpm and making 650hp, then I don't think any torque attributes that the KA has stock will matter. If you shift at 8000 rpm, you will only fall back down to 5000rpm in first and 5500 in second. So I don't see much of a point of worrying about power/torque at anything below 4000rpm (to give a little buffer for corners or something)

I have heard that the KA crank starts to have problems at over 400rwhp, does anybody have any more input in this area?

You don't want shorter rods.... you want longer ones.

By longer, I never meant thinner. By all means, make them beefy. But they need to be longer than stock, not shorter. Shorter rods will cause the sideload on the bearings to be way too high. It will lead to bearing failure and will prevent you from revving high because it makes for a worse rod:stroke ratio. The longer rods will make a better rod:stroke ratio than stock, allowing you to rev higher.

George is a lying c***$ucker...

I have a few machine shops I can turn to in the cam department. I'm not to overly concerned there. I was reading up on Duy's car. He made some real nice power with quite a bit less then I actually plan on doing. Which gives me a nice warm and fuzzy...

Thx for all the suggestions so far guys. But like EZcheese said, she's just in the planning stg right now.

For a fuel system I think I'm going with a Barry Grant setup. I've never heard of anyone having any problems with the BG stuff. Not sure about injectors yet, possibly 100 pounders.

what size turbo do you actualy plan to go with, and you gotta have nice sized chiller to compensate

. Longer rods would increase compression, right? Is that something you would really want to do, I really don't consider a street legal car that can only run off race gas to be really streetable, but I guess you can get longer rods with pistons that dip in.

Man you guys got me all confused again!!!! CA or KA?!?!??!?!?!

Longer rods won't increase compression, it will just shorten stroke. The only thing that changes compression must be done above the piston. For instance, piston dish/dome, or head gasket, or milled head.

Post by **TrueSlide** » Fri Dec 13, 2002 4:27 pm

Nice, learn something new everyday. What length of rod would be good to take the KA to about a 7.5-8k redline?

Longer rods will not change the stroke. Only changing the the crankshaft will change the stroke. The rod will stand straight up at TDC and BDC. The stroke is the exact distance from the center of the rod bearing at the highest and lowest point. Changing the rod length will not change that.

On another note, Performace Cams for a turbo and NA motor are made differently. NA cams are usually made with a good amount of overlap to assist in the scavenging effects of a well matched set of headers. If you run too much overlap on a turbo motor, some of the boost air will just be sent out the exhaust. Turbo cams generally run little to no overlap.

Doh! Thanks for correcting me. I wasn't thinking right. I tend to become retarded from time to time.

yep, i think we all do that. When i was about 5 years old I was screwing with this cool speedometer for my bike that my parents bought me for christmas, and crashed into a parked car in front of a ****load of my friends. They still haven't let that go.
