I need info on KA NA mods

they make fast spooling turbos now that make peak boost at a little over 3000rpm and hold it all the way till redline. like 26psi too. turbo lag is a thing of the past.

[JDMDrft]

sometimes turbo lag is good though, like if your dragging, you won't smoke youe tires off the start and once the turbo is spooled up, in second or even first gear, your gone...but thats only with big turbos

That is not turbo lag. Theres lag because he's doing a 3rd gear pull. If he were on the street, he'd be in 2nd gear already at full boost. You dont know what you are talkin about. If he were on the street, most likely they'd be building boost already (even 'n third gear). In many cases, with a small turbo, boost can be built at 2000 RPM which is hella quick.

most cars don't even make full boost in 1st or 2nd gear though. Also dyno pulls would matter even less since there is less strain on the vehicle, it is easier for the engine to do work. simple physics.

and we aren't talking small turbos here, I just said any turbo that makes a lot of power, that would be something big as in t4 or bigger. They have a lot of lag..... ever hear of single turbo t88 supra? I guess they are so modern they don't have turbo lag huh? lol

yesterday i decided..

today i got,....

ca18det 1200 for a front clip

rb20det was the same price....

i reccommend anyone who wants power to do an engine swap...i duno why, but just do it,,,it is so much easier and funner

if your on a budget, then swap,....

if u got the cash....build up the KA

im talking N/A KA...build it up right....THEN turbo it after u build it up......

[BuddhistWitch]

Ur not gunna turbo that mother after you put some 11.6 or 12:1 pistons on it. And I'm sure some of the others you use for N/A won't work with the turbo.

[stealthj]

then build it up for turbo

on cars with good turbos, the lag is barely there, have you ever driven a turbo car to its limit? anyways, you should only barely feel lag in first gear, shifting at redline. my friend has the t4 turbo, and i dont really feel lag in his car.

stealthj... your back? what happened i thought you were banned?

man, how can i be banned? i am a shareholder of Automotive Forums CO LLC INC.

i want to paint my sidemount and move it to the front!!

even a new evolution has turbo lag.......

[DWF Engineering]

The E.T.s you'll see are more dependent on tuning. A man has a website, search for "240sx performance", his 240sx se with full interior runs 14.9 in the 1/4. Mods were intake, exhaust, header, JIM WOLF ECU, and pulleys. In my personal 240SX LE/S I can outrun sport compacts that have been tested in mid 15s easily. The last race was against one of those new Tiburon GT V6s. I pulled him by about 3 lengths in 1st gear and 2 lengths in 2nd and 2 more in 3rd. The older 17X bhp GT V6 ran high 15s and the new one has an extra 10-11 bhp. The 240sx LE/S is lighter than the SE by, oh, say 100 lbs. It has steel wheels which increases the rotational inertia, thus, reducing acceleration. Even so, based on the cars I've beaten and the lead I had at the end of the race, I'd say I'm running e.t.s < 15.3 seconds. My mods are as follows: no engine fan, de-catted, no muffler, S-AFC, and ignition tuning. With intake, header, sport cam, port work, and milled head (for a compression bump) 13.7 sec E.T.s should be attainable.

less strain on vehichle = less exhaust gasses
that is why you can spool an auto trubo car in drive by holding the brakes, but you can't spool a manual turbo can in neutral very well, because the auto turbo car is under load, while the manual tranny car is not.
what cars don't make full boost in first or second gear?

we aren't talking small turbos? i believe it was you who said any turbo has turbo lag. you don't need a t4 anymore to start making serious power. there are t-28 turbos that bolt on to the stock t-25 dsm manifold that are good for 12 second pulls. why run a bigger turbo then you need to? if you're running a t88 on a supra, you better be making over 1000hp, and in that case, yes you would have turbo lag, but that's because YOU'RE MAKING OVER 1000HP! in realistic hp terms, you do not have to worry about lag. we are talking about our small displacement 240sx's here, don't expect huge hp at 1500 rpm- turbo or n/a.

yeah and the 4G63 t25 is an extremely advanced turbocharger
