only if you put a 4a-ge head on... you only have one single cam gear running on the belt.... then you have 2 internal cam gears... which actually run the 2 cams in opposite directions (called a slave cam setup) |

the 7a is a slave cam engine. they do make cam gears (look up 93 Rolla on nopi) but there's really no need if you aren't boosting.

because it wont make for that much adjustability and the head on a 7afe is an economy head its hard to gain performance out of it with out porting and other costly changes -------------------- 1994 Celica GT4 WRC Edition

Finaly after hard times the manifold is completed and the motor is in !
    I repeat it ; the blue look very bad because of the flash ... Now waiting for the intake and valve cover (chrome) and I'm now in the intercooler piping . There is not a lot of space for it . My car have been in accident last summer and I will send pics of it later. Now my biggest concern is for the management ; some friend are tell me to go with jdm 4agze map ecu , I have the ecu , the igniter , the crank angle sensor, the map , the coil pack, the 365 cc injectors but no wiring .... Maybe I'll start with the standard ae86 ecu and upgrade later . Claude |

how is your project coming along? I'm in limbo on which type of build up I want to do. The 3sgte or 7agte. I'm really starting to like this build up. I saw an engine on club4age It was awesome ! good luck with the project please post some more pics!
edit: lol he posted these pics as I was writing this. Defgeph This post has been edited by defgeph: Apr 14, 2004 - 10:38 PM --------------------  I will return one day. |

Go with 3sgte if you don't like to fit things (custom work) .... My motor will cost more and take more time than swapping a complete 3sgte kit . I choose it to be different and as a personal challenge .

you should use 4A-GZE wire harnese it comes with a MAP sensor.
It's does not ues a air flow meter, thats the best for turbo toyota, all the big toyota pros go that way! |

I have heard you have to re-locate the Alternator for a 4ag. Is that true?

When swapping into an AE86 or AE92 yes... but not into a Celica. You basically bolt on the head, the sensors, manifolds, do the wiring and tune it. The bottom-end can be left untouched so long as the accessories don't interfere with anything else. The 4AGE and 7AFE mount accesories opposite of each other. -------------------- "It's ok to be naked girl... I'm an artist!"

yea, just throwing this out there, those cam gears from HKS he has cost a bleading fortune.
Hey Kwanza. I am Probably going to end up doing this in one form or fashion and using it as my DD when i get out of school. I'm probably going to use 256 duration cams so my car will still idle properly. Do you think I should go with more if I do ITB's? And I am going to use the big port head. Also, HKS' cams are most likely the best, and highest quality, but web cams make some that are $330 for BOTH, not $270 someting each. What are your thoughts? |

I have now a wiring, ecu, igniter, coil pack, crank angle sensor from an ae92 jdm 4agze map dli; this is my next challenge/update for this winter. No more "us" ecu and *&?%$/! afm ! I read and look for the autronic stand alone management ; it's very complete and high quality but not really worth the cost for an 220-260 hp engine ... We will see !

There are a ton of options. I'm currently running Crower 272s in my smallport on the stock ECU and currently have no problems. I have the car tuned to run rich and have jumped the smallport high impredence injectors, so I'm pretty safe. The engine make a LOT of power... The top-end is stronger than the 20V silvertop but it's not as responsive as the silvertop from low-throttle, which can be attributed to ITBs. I'm also running a light flywheel and my AE86 is just borderline streetable. It drives excellent. A 7AGE build should be even better, but I'd reccomend you go with the smallport head. The bigport's ports are too big if you're gonna build it n/a without TVIS. The HKS 256 cams are very streetable and you can probably even hold a stock idle. It should be fine with ITBs. It's all about tuning when it comes to running ITBs. That being said, source yourself a JDM smallport ECU (MAP Sensored). It'll make your tuning life a LOT easier than trying to get a USDM 4AG ecu to work properly. You can't hook up SAFCs to USDM 4AG ECUs... at least not the AE86 and MR2 ones. At the very least, you can run OPEN ITBs with the JDM Map sensored ECUs... -------------------- "It's ok to be naked girl... I'm an artist!"

I'll be flat out honest with you. I'm going to call jet and tell them what I am going to run, and see if they can get a roundabout ecu set up for me. that way, I don't have to change any wiring, and it'll be plug and play. (plus I can fine tune with the AFC in that manner) And I also was under the impression that if I used the ITB's, the port size really wouldn't be that major of a problem. After all, the intake will be controlled by the ITB's. I wouldn't think the flow characteristics would really hurt power. I figured there would be a torque loss, but not that major of one.
IF the 272 cams are running well for you, I might just go that route. What did they run you? Also, what are you thinking for a redline. I was thinking 6500-6800. Probably 6500 because the block will have 120k miles on it. that coupled with a .7 or .5mm metal head gasket could lead to compression worries. I figure all that would Easily topple the 130 hp mark. Throw on a few basics (header, exhast work, UDP) and it could make considerably more power. In the end. I'd like to see how it would run agains a stock 7afe turbocharged. Were i to rebuild the block properly, I think the all motor 7a with a bit more compression and the above head work would easily take a 7afte. But price wise... I will probably end up spending more money. However, when I set out on this I said it would be a reliable DD, not a weekend race car. I just want a little more under my right foot. Plus, it's going to be a fun little project. |

A Custom ECU would work fine only if they can fine tune it to your car. That'll require them to have your car, run it and tune it. That might be hard depending on various things. That being the case... you should look into megasquirt or something else. Try e-mailing toyotaspeed90. He's running a smallport 4AG off of his modified 4AFE ecu... so it can be done without major wiring changes. You'll still need to splice in wires and connectors to the different sensors and ignition parts (dizzy, coil/ignitor etc...). As far as the ports go... the actual intake ports do matter because they affect velocity and volume as well. ITBs will increase overall flow but having such large ports can slow velocity. Get what I mean? As a comparison, the Silvertop 20V's intake ports are very small... even smaller than the smallport 4AG... Yeah... the crower camshafts are running great... and they're cheap too. They're much cheaper than a pair of HKS cams and they've been doing well for me. I got mine from a club4ag member for 375 shipped brand new... but I think they retail in the 400 neighborhood. The 272 n/a stage 2 cams aren't listed on their website for some reason... My car's redline is stock, which fuel-cuts at 7800 rpms (and I do rev it all the way there). The cams make power all the way up there and probably a bit beyond also... In a 7AGE... the only reason I wouldn't rev high would be because of the stock rods... but people have revved their 7AGs up to 8000 rpms in race situations and the rods have proven pretty durable. I don't know... but I would look to something like 7000-7500 rpms or so depending on camshafts. I'm also looking into possibly fitting 2ZZGE rods into a 7A block (they're scarily similar) and if that works out... the 7A bottom-end can easily spin past 8. The rod stroke ratio of the 7A bottom-end is pretty good for revving. I'm probably gonna end up doing a 7AGE build myself in the future. As for power output... a stock 7AGE can make 130hp without even sweating. So long as the tuning is good, stock bigport camshafts on the smallport head, on a 7A block with smallport high-comp pistons, can make 130 hp pretty easily. My AE86, if I have to estimate, is probably putting around 130 to the wheels. I can put 3 cars on my cousin's stock 91 240SX which is rated 160 some odd hp and torque... so I'll guesstimate it's pretty good. I'm still searching for a pair of good camgears that aren't bright purple and blue... =/ -------------------- "It's ok to be naked girl... I'm an artist!"

Use AEM cam gears. You'll pay for them, but you can get a variety of colors. That's fairly cheap for cams, and probably the way I will go. And yea, I have heard about the 2zz rods, pistons, and even crank being very close to a 7a fit. A bit out of my price range for now though.
I see what you mean about Velocity. It never crossed my mind That explains the tivis 'increasing velocity'... I have large port parts available to me. I don't know where I would look to find a small port head and intake. they cane in the late rollas before they started using the 7a right? |
