Engine Have a question with the 1zzfe engines

Well i already have trd intake, trd exhaust, headder, and not catback, also hace act clucth, and the pulleys which ones, I've read that the pulleys for the alternator don't really do much, but thats what I've read.
Thx for the response guys, its very well apreciated. If there is more please post up.

2ZZGE Swap

There's the big bore kit as well, higher compression pistons, and you can check out cams.

Have a question with the 1zzfe engines

Hello guys i was just wondering if their are any trick to do to the corollas with the 1ffze engine to get more power but without putting the s/c. I'd like to get the most out of it N/A becasue later I will put the s/c. Well thx for any comments.

Poke around, try a search, etc.

Intake
Exhaust
port/polish
Header
Nitrous (not really n/a, though)

to add to the list aboce pulleys

unorthodox makes good pulleys

*chuckles*

Please tell me how to get a streetable 240hp out of a n/a 1ZZFE..

seriously...my prayers r with u

I dont think I said anything about 240hp, more like 160-175hp.

If you're going to supercharge it, don't go high compression..you could bore it out and stay at 10:1 or drop to 8.8-9 to 1..

there is always the coolant bypass trick (off the throttlebody), its good for a few ponies but nothing major.

There's the problem, you can't get the most out of n/a if you are planning on f/i. Do one or the other.

polo708, you're not even going to get 1/10th of a horsepower by doing that, and DO NOT do it if you live in a climate where it get's below freezing unless you like your throttle getting stuck.

why build for na now, then FI later? completely waste of money and time imo..just build up for FI

N/A is best!

N/A is best for what I want , jeez.

dont do the coolant bypass...doesnt sound that great. if u live in a cold climate it could screw ur throttle body...if u live in a hot one, ur car gets hot as hell anyway. just get some rubber hose from home depot and extend ur intake tube. how come no1 has mentioned a lighter flywheel and a better clutch? or weight reduction?

A lighter flywheel and a better clutch won't give you more 'power', but yeah, it'll help a little. Weight reduction..same thing -- it'll make the car faster, but it won't add any power.

Apparently you want something different than most of us..lol

for the money it would cost to even get 160 hp with an N/A set up you could just buy a TRD supercharger bolt it on and be there.

Actually, you said that N/A is best.

I'd take 240 turbocharged horsepower over 175 n/a any day.

Shaving 10 thou off the head will raise compression about 1/4 point and add about 5 HP, but you don't want to if you're going with the TRD blower later on...
The throttle body bypass works fine down to -50* F with an Injen CAI, here in Kapuskasing Ontario, home of GMC's Cold Weather Testing Facility.
JP Performance's 2 1/2" mandrel bend downpipe with highflow cat and resonators system for $440 will hook right up to your header and TRD exhaust.
I really brought the beast out for little cash by also smooth boring the TB, shaving down the intake manifold's vacuum fittings, removing all ridges and enlarging the outlets to match intake ports, smoothing intake ports down to injector bulge tip (about 1 1/2" deep), removing the large ridge on bottom of exhaust ports' outlets, enlarged to match header and smoothed down to the split (about 1 1/2" deep).
A custom ground upgrade was also an impressive and cheap upgrade.
ASP's aluminum 15% underdrive crank pulley is a great mod for only $120. Engine feels much less burdened for a great response improvement and much easier manual shifts as RPM's drop more readily... It would also slow down TRD's supercharger by 15%, which could be corrected by downsizing its pulley.

u can take 5 thousandths off the block itll raise compression ! give ya like 20 hp! also makes your car run a lot hotter and may blow your head gasket but if u you know how to do it and dont give a damn and have an extra short block n all inthe garage like me then go ahead! other wise just buy the trd charger wont void the warranty!

meh...power doesnt really matter if ur car can still haul ass. if u could get a corolla in mid to low 15's w. no major engine mods, then whats the difference (not "a supercharger is so much cooler!!!" or "u can say you have a supercharger and it sounds good!!") between ur corolla and a corolla w. a blower that runs the same time? just different ways of dropping ur acceleration times.

supercharger would be nice tho

p.s. how much u make off the throttle body bypass and cai?

Throttle body bypass: 000000.1
CAI: 5 at best, minor loss of torque in the lower RPMs

On a Honda S2000, dyno tests showed a jump from 198 to 209 WHP with a CAI and TB coolant bypass, then still made 207 WHP when reinstalling stock intake only. http://www.vtec.net/articles/view-a...ticle_id=258732
A 290 HP Trans Am WS6's TB surface temperature went down from 102*F to 82*F with the coolant bypass and over 6 HP was gained.

Also, Injen shows an 8HP gain with a CAI on a Matrix 1ZZFE and an overall torque increase;

All these simple mods and fine details yield substantial gains by working together. Any N/A improvement beside raising compression will actually add to the blower's gain by improving the engine's breathability.

WoW thx for all the info. I am planning on making the car F/I but i doing all the things that will help the car later when i put the S/C. All the N/A mods are to help the car when I put the S/C. Want to get out all the power i can without the S/C to then put the S/C and max the car. I didn't understand some things but I'll read them later with more detail. But thx for all the help I really apreciate it.

I don't really consider mid-15s 'hauling ass'..

Anyway -- to prepare for f/i and still see a n/a benefit, you can install exhaust, lightened flywheel, performance clutch, and some electronics (eManage..leave it to stock tuning, AEM UEGO wideband, EGT gauge, etc).

Not everybody wants to drag race their corolla......

lol i know 15s isnt hauling ass...i kinda switched topics i guess you could say. has any1 gotten their corolla into the 14s?

If you count engine swaps, I'm nearly 100% sure that Mantis will run a high 14 second pass once it's done. ('98 Corolla with 2ZZGE swap).

Also IIRC, hoolala's supercharged Corolla was running a high 14 before it got totalled.

BLK03Corolla is running mid-14's (TRD S/C)
