that pm from you after my first post on this thread clearly indicates that you fully appreciate and understand my views. Now you're just clutching at straws. Stop being childish no one is saying not to build your project I was just pointing out that respectable power can be made from the GE bottom end. I also was not bashing your modifications I was bashing the other website thread and I stand by my opinion that there is no point in using the OEM camshaft with a full race engine rebuild. That's my opinion and you can refuse to accept it by all means but you don't need to resort to childishness. I will now ask you kindly to refrain from sending me pm's and I will also refrain from posting on your thread as we clearly have a communication (and intellectual) impasse.

That was before you got disrespectful and I was reliably informed by other tuners that you don't know sheit. You is just hot air. I dont know you or ever met you before, but that is just what other tuners had to say and I'll leave it as that.

I knew that something was not 100% but I always tell myself that the exact problem will show up eventually. I am still able to go anywhere though. So do I push to do the project engine or do I just change the head gasket???? Hmmmm

When a part broke, it literally broke their pockets each and every time. I dont want to be in that lot at all. If money wasnt an issue we would of been driving BMW's and Porschas.

No it's a 7A with the top and cams removed. See on the left side there are two brackets for the coil packs. And just look at the sump. And Tested performance you need a life. You should see a doctor and really get tested cause ur performance sucks.

hmmm............either thats a 7A block with a old 4A head

or its a very old first-generation low compression TVIS 4A-GE

Postby **Hook** » May 25th, 2012, 8:59 am

exactly...I suspect ol' skool TVIS 4A-GE

xtech · Postby **xtech** » May 25th, 2012, 4:44 pm

looks like Toyota went wey back into the 80's to update this 7A-FE head with TVIS
also installed a fixed dizzy and installed a dual coil pack system.... :roll:

on my 5E they have TVIS as ACIS a dual runner system instead of the dual ports at the head which should be better.

stock 7A-FE's rev limiter kicks in at 6800 rpm

measurements of the conrods and crank's big end.
Its all the same as the normal 7AFE.
Also with press fit 20mm gudgion pins.
Same thin conrods with 51 mm bigend holes and 22mm thick bigends.....not boost friendly

It also missing extra ribs at the back of the block like what Toyota gave the 2nd Gen 4AGE again which might prevent it from handling big boost.

from youtube........vs a stock gsr integra
7afe block and rods,4age redtop pistons and full floating wrist pins, 7afe modified headgasket, 7afe tranny 3.75 final drive, bigport 16v head with tvis, 440cc injectors,emanage, 7,000rpm limit to play safe but wants to keep revving, 7a flywheel,4age cranks procket and crank pulley,adjustable cams to minus 2 degrees for correct timing,4age 421 header open,accel coil,lexus mapsensor es300,7afe tps, lexus sc400 ignitor aka redtop 4age ignitor.

someone said that if you use the blacktop head with crank and pistons from silvertop you will only get a CR of 8.0 to 1 or something around there therefore you can install a turbo and run it to 8000rpm safely and attain about 165 or 170 kw (230HP) without any head mods or you can buy more aftermarket parts do more head work an run it NA........create a map up to 10,000RPM to get decent power with response around 125 or 130KW.

Awesome. Care to contribute to the technical part of the discussion?

Bigmanbandy · Postby **Bigmanbandy** » May 27th, 2012, 6:30 pm

Mistakes can be made, we are here to learn from them.
Here I put the 20V piston in the 7A block to show that the piston size is the same, cause I had the argument that one is an 1800 and the other is a 1600, that the piston sizes could never be the same. So to clear this up.

This image shows the difference in the piston itself between the high compression 20v piston and the low compression 7A.

Then the engine number on the block to prove it is a 7A engine. I marked it with a bit of chalk so that it could be a bit more visible to my phone camera. I feeling lazy to go for my good camera. I wanted to take a pic of the metal head gasket that the 7A comes with, but another day.

It was the fuel pump. Not enough fuel. Was just driving the car not really bothering too much. A mech checked it out and he said is the regulator bad, He hammered in my stock regulator which helped a very little. He say you need a new regulator. I had another home. changed it and it was the same. So I thought old engines let me go get an aftermarket FPR. Got me a Aeromotive compact EFI. Installed it myself. Didnt know what pressure to set it at. Another guy told me 25 PSI. At 25 PSI fire was literally coming out of my exhaust, hot agressive or anything, more like your car is on fire. "I not joking I very serious, so I realised it not safe, I sent the pressure back up to 2.8 bars, which I found with google. But still not working good. But the man with the performance shop said "is your pump" from the start. He was able to say exactly what the problem was over the phone even before I bought the regulator from him.
Big up to Blue Choral Racing in South. I believe if a man good big him up, he knows his sheit. He didn't have this fuel pump so I had to bring it in. Just need to install it now, but the custom exhaust I put in is in the way. Long story, so I have to install some flanges.
