Planing ahead / thinking

[Sleepy_Steve]

Next summer i was planing on leaving the N/A KA boards, and spending more time here.

The goal is a Daily turbo'd KA making 200-250 whp. Thinking ill get a used KA and build / rebuild it for turbo. More for learning how to rebuild an engine than for power.

I was wondering if there are any relativly simple things to make the instal of a turbo motor easier when i get there. Such as getting electric fans instead of that clutch driven fan that seems to slip above 5k rpm

Anyway, what can i do to a NA motor to make turning it into a Turbo a bit easier?

No, i dont have the speciffic turbo picked out atm... as i havnt even come up with a budget for the project yet. But if anyone has any recomendations im definetly open to em.

Research whats in a turbo setup and you'll see a few things that can be reused when you go turbo. You wont have much use for headers or intake.

You could install electric fans now. They arent necessary for a turbo motor, but they cant hurt. A nice 3" exhaust would be a good buy (but it'll be pretty loud til you add a turbo).

Just save your money and carefully plan a turbo setup...

BTW, did you buy your car from Hashariya (Chris)?

just research this site and Ka-t.org for a lot of info on turboin your 240....it all depends on your goals....if you want 200-250hp im guessing you want quick spool so id say go with a t28 from a s14/15 sr20.....a nice 3 in catback, tuned ecu so you dont really have to d!ck around with a dyno...some 370-440cc injectors would do fine...possibly a n60/n62 maf for more hp capabilities....and intercooler.....either a FMIC or a stock SMIC which wouldnt be the best option

LOL, yes - same car. For now im working on the 5 spd swap so i dont die a little inside every time i stomp on the phantom clutch, or do anything that makes me glance in the direction of the gear selector, and the whole omnipresent lack of throttle response... yeah, i realy dont know how people can DD autos, it makes me sad. Although the trafic in this area can sometimes tempt anyone over to the dark side i suppose... oh man, i digress.

Yeah, the fans are more for space, and not hearing that damn belt slipping at high revs, it anoys me, and i cant think of any otehr belt fed device up front that would be slipping.

Quick spool time is one of the things im going for as my power goals are relativley low. I've been told good things about the t28 from the SR's. (can anyone give a more complete name for the t28 to improve the results google gives me??)

You guys answered many of my starting questions though, so thanks! I'll eventualy do the fans and exaust minus headers... But for now it looks like im much better off focusing on drive train and interior.

Drive train. Doh! Which reminds me, i need to resume my search for some 5 bolt rear axles.

search for 'sr20det t28' or'nissan t28'I found a site that tells you more about the different SR motors and it also mentions the turbos.http://www.angelfire.com/my/jd....html

Another possibility is the Pulsar GTiR turbo. Its a lot harder to find in the US than SR turbos. Heres a link to a new one.http://turbostore.com/garrettt28.html

Wikipedia also has some good info.

See ya around. I live in Silver Spring...

Oh damn. Thats like ten min from here... I'm just north of the Beltsvile agg farm.

Thanks for the links btw.

Just my .02, but a T28 is far to small. I would design a turbo kit with room to stretch it legs. Boost is like heroin my friend...once you start, all you want is more. So realisticly I'd get the basic T3/TO4E with a .63 Ar exhaust housing. It's a completely proven turbo for the 2.4 KA. I ran one myself till I wanted big boost and tossed a rod through the block. The spool is more then good. If you have a turbo that spools in the very early rpm band, say 2500, then it's a heat pump. All manufacturers use turbo's that are to small by design. They know the public wants boost right now with no lag, but they end up using a turbo that is almost at it's limits and becomes a heat pump and choke point.

When it comes to turbo's, your almost always better off going one or two steps bigger. The efficiency goes up and the charge air temps go down. Cramming hot air into a motor is how most of us detonate and pop pistons/ring lands etc.

One thing you can look into now is the fuel system. Swap out the pump, you may run a tad rich but nothing you'll notice without a wideband. Check into what style injectors you want to run, top feed or side feed. Side feed's allow you to keep the stock fuel rail, top feeds require a new one. You'll need a good fuel pressure regulator, tuning the base pressure is often overlooked in tuning. You can pick up a few gauges and have them installed and functional that way you don't end up driving and playing the guessing game we all have done...lol. I'd suggest a Fuel Pressure gauge, a Boost/Vacuum gauge and an Oil Pressure gauge to start off.

Start thinking about what type of engine management you want to go with. Piggy back systems like the SAFCII or III are decent for a low boost setup. The MSD BTM can handle timing retard on boost. Both are simple to install and tune. I use both of the above. Or you can get a ECU from someone like JWT that is set for a certain injector combo. Just make sure you pick the ECU/Injector combo at the same time so you don't buy anything twice.

A good catback exhaust has already been mentioned. Hmm....thats about all I can think about at the moment. You can read Corky Bell's Maximum Boost, I just read it myself...lol. I've been doing some things wrong for a long time...LOL. You can never know to much about anything.

Well, you have a few things to think about so do some research and start building a list. Best of luck and happy boosting...

what about a gt2871R??? that is good to up to 400hp...that is more than enough to satisfy anyones needs....and with quick spool too

[hannibal]

Its a nice ball bearing turbo, but its also twice the price of a T3/T4 or non BB GT32. And the GT2871R will need more boost to see the same power as the larger turbos.

[WDRacing]

Here's somthing to consider if you want a BB center section, buy a used T3 from a Skyline GTS-t and just use the centersection. Then you'll have a BB T3/TO4E...Thats what I have right now. Just plumb some water cooling lines and you're all set.

The 2871 is a good turbo, but again, I'll take a T3 .63 AR exhaust housing if I have the opportunity. More exhaust flow is more exhaust flow. The compressor may flow enough volume to support 400whp, but the exhaust side is still very restrictive.

Again just my opinion.
