Time to Spend $$$$
« on: Jan 8, 2003, 09:43PM »
Gday Guys.
After spending a whole day, working on a mates 180sx, then his dads sti, believe it or not, but I have decided to keep the TRX. Why? Because they are unique. Even more of a reason cause I still love it and cant bare to part with her.
So, I made the decision to instead of and Engine swap, to see what this KA24E beast can do. An original motor that I have yet to seen really worked.
So guys, Where do I start with the beast?
Also for a change, I was thinking of keeping it a N/A engine.

I know there have been heaps of posts about what to do when modifying your engine, but Im serious this time. I would like some advice on where to start etc.

Id love to crack for a 14 second bracket keeping it N/A. Thats my goal.

Less, if I go a blower or hair dryer.

Ideas anyone?

Cheers, Mitza

Hey Mitza!

Since your serious [this time], the best advice I could give you would be to invest a small amount [time & $$$] in some technical / automotive literature.

One of the particular books that I own is called 21st Century Performance. See AutoSpeed link for pricing and details - its all outlined here chapter by chapter.

The book covers everything from DIY's to major build ups. It is categorised into: Engine and Driveline, which covers cams, head porting, gearboxes etc. Electronic Engine Management [and modifying it]. Air Intake Systems. Exhaust Systems. [turbo and super charging is also included]. Fuel Delivery Systems. Performance Testing. Tyres Suspension and Brakes. Aerodynamics.

There are over 350 pages and plenty of info for N/A projects! A worthwhile investment for any car & diy'er

Have fun.

I'm picking up my reground cam tommorrow..... ;D
Can you say lots of lift and even more duration?  ;D ;D
It's good to see someone else keen on an NA buildup, especially after hearing about that Corsair (KA24) at summernats.....
One suggestion: intake manifold insulators. PM me for more info.

Oh yeah i have 21st century performance and it's definetly a good read with HEAPS of illustrations. I need more specialist books now (ie cylinder head modding).

If you have a bit of Mulla to spend and do not want to muck around then I know a company on the coast that could get you a heck of a lot of power out of your engine.

You would need to give them your head and then give them a hp figure you want, then they would use a pro flow bench to custom port the head for maximum flow. Prolly around 250hp would be a good figure.

Then you would need to get more fuel, puter and injectors etc....

It would not be extremely cheap and would prolly be at least $3500+ but only cause they guys build drag cars for a living. The flow bench they use is worth like $80 G's or more so you pay for the time. But these guys could get the most hp out of the KA24E that is physically possible...

I still think that after you spend all that money then you could have a sr20det under the hood for not much more and just up the boost a few pounds and be quicker anyway...

I could imagine they'd go through quite a few KA cylinder heads:
No. 1 to dissect to see what material can be removed and where
No. 2 prototype with reshaped ports/combustion chamber
No. 3 replacement for No. 2  ;D
No. 4 final piece of artwork  8)

sorry for the ignorance, but is ur 2.4 related to the motor in the 240sx? if so there are some really good pages about perfomance upgrades, and of course, people debating whether they should go the SR20det option etc, its pretty interesting, but i dont have the link, if i find it, i will post it,

Correct.
240SX = 2.4L, but in RWD. That is the biggest problem in comparing the two - FWD vs. RWD.
200SX = 2.0L
180SX = 1.8L, etc., etc.

I dont mean to be picky but i thought you could ALSO get a 180sx with the SR20DET engine - which would mean: 180SX = 2.0L [also]  ???  8)

OK the 240SX is a DOHC model of the KA24 motor - Has the KA24DE in it unless you look at the 89 models they have same motor as the TRX.

If you want to find some really helpfull hints for our cars then doa search for STANZA as this is what they call our cars in America.

I have couple here i`ll share with you:

im guessing though its not an easy swap to  put the DOHC head on the single cam motor, how much are the KA24DE's from wreckers, and they should use the same mounting positions you would think, so maybe that'd be a good swap

WHIZZN: Been through all those pages many times before, they have nothing to do with engine modifications, apart from boltons. Ashura's page is good cos he's shown what he's doing with his suspension. If you want to find out engine modifying info, you'll have to go to pages/forums (like fresh alloy) for 240sx's.

anotehr good site is sr20 hydrids, which is a site dedicated to 240sx sr20 swaps... however, a rwd engine swap is quite different to the fwd engine swap. but they give you wiring diagrams so that may help. but then, the ka24 wiring may be different in the US, you never know..

I rang a few wreckers a while back and only one had one at the time and the guy wanted $1500 for it...

It is pretty insane cause for the same price you can get SR20's even a 2.2L Honda vtec engine for around the same price and then got like close to 140kw...

If I did find one for a good price tho I would consider getting one, but I want to test drive a manual SSS bluey with a KA24DE in it to see what they are like.

I have found a site to two that reckon they have cracked the cams for them, and can get some really good power gains with certain regrinds..

The head off the KA24DE will not fit your motor.  You will need to buy the whole motor and do a transplant - Not too hard, just get computer and loom with it if you do.
Loom might be same but never know, definately need computer though

u would think there would be a few of those motors kicking around, cos the u13 bluebird had it, as well as the 240sx

Personally i`d like to see someone put the KA24DE in one of there TRX`s and put on dyno in standard form to see what differences there are to be had.  I mean you`d have to do this to a standard KA24E motor to get an accurate measurement but i think this would be relatively interesting.

Another interesting fact is that these motors lend themselves particularly well to turbocharging as well.  On the Dyno 2000 program i have on computer i have been able to make one of these motors produce more than 500HP.  Now fair enough it would be relatively expensive to build such a motor for our cars but hey, how many other 4 cylinders could make this type of power?

Yes i also know there`s a lot more variables tat i can put into this program to make it MUCH more accurate but as at this time i don`t have flow figures for the standard heads or modified ones for that matter so these figures are based on some seriously based drag prepped heads that the program has in it.

Plus for those of you who the insurance companies don`t look upon very favouribly maybe just a souped up N/A version of the DE motor would be in order.  Hmmmm, there`s a lot of variables i need to have a play with, i`ll get back to you  8)

There is a guy in brissy who is nearing completion on a SSS Bluebird U13, with a turbocharged KA24DE in it.

He said he was confident it will be making 500HP+

He works in a performance shop so he can get it all at cost etc.. but said it is quite an expensive process...

But when that baby is ready I will certainly want to have a look at it...

KA24DE has like another 16kw and prolly revs out faster, and there has been a bit more work done on cam research with them too I believe.
It is just a pitty you cannot get a front cut with them in it. They cost about $1500 just for the engine at a wreckers but I am sure with some constant looking one could be found for a bit cheaper.

A lot cheaper - I rang some wreckers a few weeks ago and got best price of 900.

Pays to shop around a bit

i was considering getting a U13 bluey before getting the magna, then i saw that insurance for a Bluebird SSS was twice the price of a magna.
strange considering:
bluebird 112kW
magna 140kW

although weight differences between the 2 make performance statistics closer than these figures suggest
