Ebay KA24 SOHC turbo kit.....at least a good starting point?

Post by bonylad »

I am picking up a 94 D21 Hardbody. RCSB with a manual trans and around 100K.

I am aware I need a top mount manifold to run anything. Assuming a ebay turbo kit is a starting point.
Anyone have input as to whether or not an ebay turbo kit is a good stepping off point?

Unless my research shows another option on the low end so far as fuel management goes, I plan to run a 8:1 FMU.
I wish it was simple like the 7MGTE where a Lexus AFM and 550s are basically a match so far as what ya need for fuel management.

I do have a 340 lph pump which is overkill but I have it...so why not? The goal is right to 200 whp. So perhaps 7-8 Psi on a internal waste gated T3. I have had several forced induction vehicles I have built over the years (I am 43) so I feel I am knowledgeable enough, but I am always willing to learn more - especially on an unfamiliar platform.

So according to the FAQ, this should be ok. Just looking to hear some suggestions.

If you want to try to go fast with cheap Ebay stuff it will at least move you around faster. Some are junk. Some are copies that do work. I couldn't tell you which is best in that area.

You have left out a way to tune timing and that will break your engine even with 200hp. Best to get an ECU that you can tune like a real-time NISTUNE or NISMOTRONIC. Then take out a degree of timing versus PSI of boost. For cheap side of things... It's been a while but I think you can get a socket for the SOHC and it is cheap. It's harder to get a SOHC ECU that has the data cable for data logging.

I would suggest better injectors instead of the FMU. Usually you can figure out another car that has a step up in the same type of injector and get some cheap re-manufactured ones.

Don't forget the AFR gauge too.
