Hey guys,

I apologize for this being my first post, but to be honest, it take several months just to read all the posts in the naturally aspirated forum. I need some advice from the n/a gurus on the next step with my 94 Hardbody KA24E buildup. Here's a list of the modifications I installed this past year:

Doug Thorley Header
2 1/2" Exhaust (no cat)
Weapon R Intake (only one offered)
Electric Fan
EGR Removed
Maxbore TB
SCV Removed from Intake Manifold
89 240sx cam
A/C removed
Royal Purple 5w-30
TB Coolant Bypass
NGK Plugs / Taylor Plug Wires

I've already removed the tailgate, spare tire/jack, carpet, radio, etc in order to get rid of excess weight. The truck will be going back to the shop in 2 weeks to have the following put on:

ASP Pulley
Timing Advanced (93 octane)
Nismo Cam Gear

My question for all the gear heads is what should be my next step with the SOHC? I've heard nothing but good things about the ASP, but does anyone here have the Adjustable Cam Gear on their SOHC? I'm curious to know what is typically the best setting for better high end.

Other than that, I'd love to hear what would be the next step in you guy's opinion. I'd love for this truck to be a strong daily driver, with the occasional drag run, all the while remaining perfectly streetable.

 

itbs, port and polish, bigger cam. polished, balanced, knife edged crank, high compression pistons. run some 15x8s with a negative offset and flares, coilovers conversion. lol your geting me all excited, id love to build a mini truck. itd be teh sex.

 

I do have to admit that building a quick little mini is unique, you're right about that. I've been thinking about going ahead and purchasing a cam, but since JWT quit making them for the hardbody and NISMO no longer has them in stock, my only other choice is PDM-Racing/Colt Cams. I really don't want to modify my cam towers by having them milled, so I've really got my eye on the C.406. As long as I get around 6-7whp out of that cam, I'll be happy. Anybody on here have that cam?

 

In any case solid lifters with valve lash adjustment are only $300, plus a high lift came to make 20+ more HP is worth it if you ask me...

 

I probably would have opted to go that route Vinnie, but the only place I know to get the solid lifters was through gabe at hybridka.com. But after emailing him periodically throughout the past year with no response I decided otherwise. No doubt that setup would make great power, but I'm forced to go in another direction. The C.406 will only be the cam of choice until NISMO or JWT start production of their performance grinds again. Any other suggestions? I don't know if it'll help, but I'll be more than happy to go dyno the truck after the pulley/cam gear is installed and timing is advanced. That way you guys can get a rough estimate of the power output of a motor with these mods. I'd love to hit between 145-150whp.

 

can u please put a pic of this beast up here. im excited. good luck with it bro.

 

Sure thing. Funny thing is, I haven't spent a dime to fix the exterior of the truck. Looks like a stock silver hardbody with the horrible factory green decal. Rust all around. Faded paint on the hood and roof. Not to mention a dented front end from hitting a bicycle that someone left laying in the middle of the road one night.

I guess you can call it a sleeper.

 

FYI: the tailgate doesnt weigh much, and removing it increases drag. My dad explained it to me one time. Anyway... Building an all motor hardbody IS pretty neat, I thought about it myself. But have you ever seen the rb26 powered ubersleeper hardbody? Look it up... its pimpin. Theres also a hardbody here in town with an sr... it stomps the **** outta vettes...

 

At this point I'm just trying to remove as much weight as possible. I understand the whole issue with the tailgate, but the way I look at it; 20 lbs is less weight I have to haul around. I have to admit that SR powered vehicles are fun. My little cousin has a 90 240sx with a lightly modded red top SR20DET. We go to the same mechanic and he loves the fact that I'm building an all motor KA24E especially in a hardbody. We're shooting on having the motor around 165-175whp in the next few months, hence the need to go to a dyno to see where we're at so far. Hopefully the ASP pulley, timing advanced (93 oct) and cam gear will be installed in the next 2-3weeks. I've already got the money for the C.406 cam and Apexi SAFC (just debating on which one to get: SAFC II or the older stlye). And to be completely with you guys, I try to stay current on most 240/Hardbody boards (club240, 240sxforums, nico, nissanminis, nissancustoms, etc) and the advice, comments and knowledge I find on this board is much more helpful. In fact, I'm using Big Vinnie's 200chp post as a guideline to follow.

 

Personally with your mods I'd say mid 160'sh hp and we can start placing bets now.
As far as Gabe I believe that the business that he is in, is in restructuring the company and has been for a little over 6 months.
I found a thread several months back using toyota solid lifters from a older model corolla I believe ( I could be wrong) for the KA on Altima and truck engines. Give me some time to look up the info. But it should be relatively affordable from wrecking yards with minor modifications. If you google search you may find the info before me...

 

Just to give you guys an update. I arrived at work this morning and my ASP Underdrive Pulley was sitting on my desk. I took 5 weeks to be made since they don't have them in stock. Looks like a very nice piece to be honest. I hope that the performance is work the price $125. Once the cam gear gets here, I'll go ahead and schedule a day to have it all put on and dyno tuned.

 

sound pretty sweat its kinda cools sein someone buildin a mini truck that doesnt have airbags and thats all show and no go. good luck to ya.

 

Thanks you guys for the compliments! I spoke with Don over at PDM-Racing today in regards to cam possibilities. He would like for me to try out his new Tri-Flow setup that wouldn't require the milling of the cam towers. His initial tests show arouns 12-14whp on most 240's. He's also running an automatic Tri-Flow setup on his winter beater and said that the power difference is extremely noticeable. He's supposed to be checking and see if it's possible to run one of these setups in my truck. If so, I'll be placing an order in the next month and doing a before and after dyno for him. If the tri-flow is not an option at this point, he would like for me to install the C.406 mild cam and post dynos for that particular cam since he doesn't have any to post on the website. I'll keep you guys posted on his response.

On another note, I'm curious to know what kind of experiences you guys have had with the ASP pulley on SOHC? Any noticeable increase in power in the top end, say 3rd through 5th? I'm anxious to install it and see what difference it makes.

 

It will make power on the truck I know several people running the Tri-Flow on the KAe truck engines. It does make noticeable improvements, but it won't make as much power as it does on the 240sx KA24e engines.

 

very cool... i'd say go for a 240 KA-DE because of the availibility of parts, but you have already put a lot of money into your KA, it sounds like. o - by the way JGYcustoms.com has the gnarliest SR- powered hardbody.
