KA vs. SR could get ugly

[creophus]

That's not bad...how much power should I expect with just the things that you listed above??edit: Also, where can I find those parts at those prices?

[I am Technoman]

You really have to shop around. Allot of those prices are on used stuff like the injectors and intercooler. There are some other things you will need also so that I did not list like oil lines fuel pressure reg down pipe and so on.....

If you can get or borrow a wide band o2 sensor and tune your car with it on a dyno you would see nice hp!

hmmmm i was thinking going with jim wolf items now what about like exhaust and other items jim wolf doesn't make?

[I am Technoman]

With turbo exhaust bigger is better.

For a good "home built" turbo kit I came up with about 2,600for a KA with stock internals.

all depends on where you get the parts... i.e. if you want a remanufactured turbo, or one off a junked car. it's possible to do for under $1000, but more a more realistic minimum is $1500-$2000.

Wow, that's alot of thread to read!:pface

I considered swapping out my KA for an SR,CA, or even RB. Then i started crunching some numbers about what it would cost to build each engine up to 300whp. Including the price of the engine, guess what? They're all about the same give or take 2-300bones. In the end it all came down to parts availability. Single cam parts are dirt cheap. You can get an entire engine and transmission for about $300 bucks. There's no shortage of them either because people keep getting rid of a descent motor because they think it will be cheaper or easier to make power with the SR. Both motors are great, but honestly, with all the stuff available now for the KA there really is hardly any point in swapping. No offense meant to the SR20 guys of course.

I'm sticking with my KAE. I'm going to go turbo with it and hopefully get 300whp. But before i get the turbo i'll be getting the exhaust and everything else ready. My car is stock...

[Turb0wned]

i would go ka-t over the sr, alot to do with the budget it all depends how much you want to spend i've seen some ka-t's run hard and i also like the fact that ka's have an iron block but which ever way you go goodluck

[I am Technoman]

If I boost on stock internals and blow my KA. I know a nice junk yard that sales used KA's for 350 complete!

man that was the biggest waste of time ever, i cant believe i read the whole 9923238293729372 pages

[elballoonrat]

didnt read all the posts but did anyoen point out....

ka is iron block, sr is aluminum correct?

depending on your driving situation and climate this could have some affect on your choice, a sr with sleeved inserts into the head could be pretty sweet.

I'm PRAYING that by the time I have my 90 Hatch built up(suspension, Silvia front end, 5 wheel lug conversion, etc) I'll know what I want to do about the engine side of it... Right now I could go with any of the possibilities.

Problem is, the car has 208k miles on the frame, and the motor, and it's an automatic(transmission swap soon as I have the car apart and know what motor I'm going)

[Trppen37]

I am goin KA-T for the knowledge...

I didnt read all of the posts...but i got the most of what all this is about. I read an interesting post a few weeks ago about overlaying an sr's dyno chart over a ka's dyno chart. It was very easy for me to choose which motor I wanted for my next project car. In the past I have built both cars up. I havent worked on the rb motors yet....not sure I really want to. back to what i was getting at. when reviewing the dyno sheets. the sr with almost the same mods and a bigger and better turbo(3037), made just about 20 more peak power then the ka. They both pulled to redline but the ka delivery was much flatter and more horspower was available for much time in the rpm band. What good does 20 extra HP do you when your only there for 500 rpm's? If a ka makes no less 300 hp from 4000 to redline, and the sr makes the same power but only 200 at 4000 and then hits a peak at redline, the sr will get it *** handed to him. As for the head comments that differ from the s13redtop and the s14 blacktop vtc. Unless you are fully race porting and polishing, these is no benefit to going high-port(redtop). Ka's power delivery helps it win races over cars with higher peak horsepower. Peak hp doesnt win races. Power delivery wins races. And one last thing....speaking on the torque of the ka. Horsepower doesnt mean a whole lot if you dont the torque to put it to the ground. HP gets the glory but torque wins the races. That dyno i was talking about- the lowest torque reading on the ka was still HIGHER than the highest torque numbers for the sr. thats pitiful.By the way, did anyone know that sr motors arent even nuilt by nissan? Ka's are- rb's are- ca's are...but sr's arent. i dont htink the vg's are either....wierd.

[creophus]

So who builds the srs if its not nissan??

I only agree with you on this because of the available gearing. Give me a choice of all gearing and in almost all cases, the motor with the higher HP will win.

It's all about the area under the curve...
