Tell me if this combo would work... keep in mind i am salvagin parts that i am handing down from my other car (HAMMER, the T78 Z31). Anyhow heres what i was thinking.... 2 options...

Option A..

1. T3 turbo from 84-87 300ZXT2. SDS EIC (Extra injector controller) with some of my old 550CC injectors from the HAMMER for fuel control.3. Isuzu NPR intercooler (13.25x24-2.5), another hand me down from the Z. ( i am going with a Greddy 3 row)4. Walburro 255 pump and possibly an aeromotive FPR5. Some sorta clutch.6. MAYBE some PDM racing cams.. i dunno. 7. I'd most likely need a turbo manifold of some kind... Revhard? custom?

Option B..

The same as above but replace SDS EIC with NissData.. and use 4 550CC Hammer injectors with a custom fuel rail since i just cant plumb them into the intake...

well since the turbo is 50 dollars or less (most likely free). the EIC is 450... intercooler and injectors for free. fuel pump is 90 dollars. clutch 350. cams are cheap i cant remember the price... so really the extra cost comes from intercooler piping and i think i can get that done with discount auto parts pipe bends.. All tuning would be on a dyno with a wideband o2 to get things right and save 12.1 or richer on boost..

NissData won't work with a KA.Cams: maybe a stage 1. You don't want anything too drastic for turbo.Turbo: the T3 should work pretty well for under 10 psi, providing lots of low-end torque.Extra injector: why not get a FMU? Nsport uses a 7:1 Vortech for upto 7psi. Probably a 10:1 should work at 10psi (don't quote me)...Too much hastle for an extra injector, IMO.Intercooler: always a good idea! Consider a bigger one for >7psi.Manifold: Revhard won't fit the KA24E I don't think.

any 16bit ECU can be programmed by nissdata.... FMU also isnt tuneable on a dyno...

The isuzu NPR intercooler has put my Z through 25PSI from a T78 turbo and its been fine... since on a dyno we made 357RWHP at 14psi (we backed off raising the boost again due to a critical SDS error that day with the crank sensor.)

As far as a manifold? does anyone make one for the KA24E? I figure as a last resort i could call SDS and ask for the schematics of theirs ( I know it annoys them when people call asking if they actually make them cause they dont).

Maybe i'll end up just going SDS on this car as well. it'd save me a LOT of hassles..

*** EDIT *** Sorry if that came across as a flame.. i'm having a bad day. but thanks for affirming the T3 will do fine, and since u had no comment on the rest of the fuel system I guess I did ok there.

It is interesting what you say about the Nissdata, people with turbo KA24's are going to great expenses to handle the engine management. There are better alternatives to standalones, piggy backs, and JWT. With some GM ECU's you can program the ECU itself with a laptop (not piggy back only altering MAF and injector signals), just like what JWT does but with your laptop on the fly. I have seen guys running GM ECU's on 73 dodge dart turboed slant sizes. Basically what you do it change out all the sensors to GM and wire in the GM ECU. I've been looking into it but dont know how the ingition on the KA works.

I too have heard about the GM ecus. Questionable to me still though.

Hey slash, i know you from Z31.comGood to see you here! Did you get a 240 from all the talk i talked about them? LOLGood to see ya.

no i got a 240 because of the tampa guys.... they showed me how capable the S13 chassis is. and mattback helped me find one.

As far as engine management. i dont wanna play around with some GM ecu..... i havent seen a car with it, and when u include the cost of a laptop, its gonna be more than SDS PEROID... i can get a sds system for that car for much cheaper than the retail price. so unless u can get a bit under 1000 dollars for a laptop and a "GM" unit. its not worth it for me

sapix @ RHIT : thanks for the mainfold information.

the problem I see with SDS is the hall effect trigger, looks like you have to fab something up and drill a hole in your block.

Do you really think that you would need another row of injectors for 10psi? What if you just put on the fuel pump and increased the fuel volume, or would that put too much strain on the stock fuel injectors? I'm sorta new to the whole KA-T thing but have been considering it for a while now. Your setup doesnt seem like it would cost TOO much money so I thought that something like your setup would be good for me also.

the hall sensor is not hard to use... you need an extra crank trigger and them some sort of bracket..... on my VG30 AND on the KA24 there are holes already there that u can use.. they serve no other purpose and just cut the bracket out of alumnium and you are fine... now the reason i wanted to do the SDS EIC with the extra 430cc injectors is this

1. Its cheap, 330 for the kit..2. It allows tuning of the fuel curve. not just an FPR that bumps the whole curve up due to pressure, straining the stock fuel system.

now the downsides..

1. SDS EIC is not perfect, its a rough tuning unit, but it does come with its own injectors making that worth it.2. I can use the factory computer and all the AFM and all that so i dont have to change the configuration of the engine bay as much. but this still means i am slowed down by the air flow meter..

All in all the SDS EIC was to be used for budget application, i would probabally have it inject a lil rich for safety's sake. U can also hook the SDS EIC up to a tank of race gas or methanol and then it could inject that instead... that would allow me to have more tolerance for boost, but personally i only want to worry about pump gas since thats enough to blow a stock KA24e anyway..

All in all this project wont happen for a long time after i finish the next stages for the hammer. which are gonna cost me a LOT..

Greddy 3 row supra intercooler, 1000CC injectors.. the most insane cams i can find.. 17 inch volks TE37 in black (gunmetal grey).... roll cage... halltech E11.... possibly GT35R turbo....

By this point about 12 months from now i'll be set up for the final evolution of the hammer.. Since the weakest part in my motor is the stock crank, it will die first.. i have carrillo rods and to spec venolia pistons, 90% of the motor is redicilously strong. Nobody has the stress limits of a stock Z31 crank. they all speculate on Z31.com if its 400whp 500whp 600whp.. my only guess is 550... but once i get the supporting parts past the engine, i will put the hammer on the dyno with race gas until i break that crank............... then after that i get a VG33 block, with a forged crank (stock) and i take it and dump 5000 dollars in internals into it.. biggest cams i can find.. and go supra hunting!!

Naturally ghetto turbo is gonna have to wait... if ya'll have any other ideas please post them, i'm sure someones got tricks up their sleves still

These standalones look real good for a moderately modified car: Link Engine Management (LEM) $699USD , I read the manual and it looks like you can tie right into the distributor no fabbing a trigger. Does anyone know where to find good info online about the KA24DE ignition?

Are you sure that your crank will go on you? I've read somewhere on the forums that the KA crank can handle I believe somewhere in the area of 950 hp. Now dont go quoting me on this, its something i read and if somebody finds a post that says otherwise, please feel free to correct me.
