suggestions to make it quicker?

[NorCal_N/A]

so i have a 93 n/a. yes i know you cant do much with a n/a. right now it has headers, intake, exhaust, what else coukd make it quicker? any suggestions are welcome! thanks.

Pulleys. Pretty much all there is left.

My suggestion in it being an N/A would be to upgrade suspension. Suspension on an N/A is much more gratifying than any engine performance mod, ever.

Crank and water pump pulley, Dual intake with Selin device, lightweight driveshaft

Dual intake with Selin device

i don't think they work for nas.

^ this guy put one one (or so he says) and had a pretty impressive gain. you can't tell if it was from the tune or the intake because they were done at the same time.

They work for NA's. There are a few who have done them. My friend put one on his j30 and saw 13whp gain (multiple dynos back to back before and after)

Oh and i forgot, lightweight clutch/flywheel combo. With all that, response will be much better. Some NA's have broken the 220who barrier. Beyond that, you will probably need internal engine work. With 220whp and suspension mods, it will be a fun car to drive with great response.

ok thanks guys. i apprciate it. and with my taxes i plan on lowering it on TEIN s-techs and concentrating on suspension. then im just going to just start saving for the TT swap.

in that link to specialtyz's blog, the car puts out 225rwhp+?

if a stock na is 222hp to the crank, let's say you deduct 15% due to friction (30hp about?), all those mods bring you back up to the 222rwhp+, right? i have a tough time thinking the selin dual maf's is responsible for HALF the gains (the 13rwhp you're saying).
sure it's going to increase some power, but not worth it, the whole selin pack is 400 bucks+, not including the two pop filters, and a second maf, 550 bucks+ easily. but if you're going to do a tt-swap, sure, get it.

[awesomekasim]

I didnt see specialty Z's blog yet. There is a guy named rockchucker on 300zxclub who i believe has 222whp with every bolt on and NO engine work whatsoever. He is also running the selin device. I have seen many stock NA dynos and they usually put out 175 to 185 whp. The 13whp may not be exact but my friend did 3 dyno pulls back to back, installed the selin, then 30 min later did 3 more dyno pulls and saw an average of 13whp in gains and 9 tq. Ill tell him to post his dyno sheets.

NA's are hard to squeeze power out of after that though. TT swap is ideally the way to go if you want more power but NA with 220whp would still be a fun car.

The selin device itself is about $280. You can find an n62 MAF at junkyards (sometimes) for $20. Get 2 90 degree elbows and a second air filter and you are probably looking at $400 if you know where to shop. Also you can still use the same setup if you go TT. Definitely a good modification if you ask me

if you are really trying to make the NA faster then save the money and either do the tt swap or get a tt.

He is in Northern Cali.. Head to a mountain and get a radar gun :-)

I have an 89 swb na slicktop.....custom ecu, dual air intakes, underdrive pulley, electric cooling fan and no a/c and it runs 263 bhp at the wheels all with standard internals

Show the dyno or it didn't happen.

OHHHHHH cant wait to get home to the scanner this weekend...... might still have the first run on the dyno before running the new map.....base map and 20 mins tweekin' gave me 261.5 at the fly

Was the 20 min tweeking for you or the car?

how are you measuring flywheel horsepower on a dyno? anyway, if you are claiming 261 at the flywheel, that is nbd because it translates to maybe 215 whp.

The only thing you can really do beyond what you've done to make power on an N/A is cams. The guy on SZ's blog only had reground cams, and they said that he could make more power with high-lift cams. Apart from that there's not really much you can do with an N/A to make more power.

It's kinda sad to see 2.0 liter N/A Honda engines that can produce close to 300 WHP, but a 3.0 liter can't. Oh well that's technological advancement for ya I guess...

what 2.0 liter na honda engines are close to 300whp?
the best one, i think, is the honda s2000 engine, and that's 240hp to the crank.
torque, there's no comparison.

The h22a's are a pretty impressive 4cyl for a n/a. My corrado's 1.8l (g60) is an impressive little engine as well but then its forced induction.

Especially if its an H2b setup
