And there is the best answer you can get on that query! My current planned project is the 40mm crankset with whatever pistons, not yet decided, with my 7lb flywheel mildly ported bigport head and 256 cams, 10.5 compression. looking for a neighborhood of 160hp. Should be a good combo for street. OST...

guys I have another questions. Im recently looking at the crankshaft of all 4age's and found that the BP 40mm journal crank have around 11.40 KG while the 42mm BP and SP journal crank has 12.40 KG, so that is a 1KG difference,, and also the earlier BP has small and lightest conrod. after reading som...

For the cost of a 20v engine you could probably build a 4AGE that would make you happy. The real savings would be in the installation, finding the necessary parts and time to do the swap. A beams 3S VVTi would be fantastic! But the query was about the 4AG family engines. My favorite combo for daily...

yup blacktop really is a better choice for instant power for the buck... but I want to challenge my self, getting a much lesser power motor than a blacktop and making it more powerful and learn from it, if I would like I can just go with the 3sge as it has more power than a blacktop but I wont as I ...

Ok i get it now ... guess i wasnt paying attention to my teacher during collage days ... thanks for taking time to explain.. on the small port graph with cams and more compression set up the power is still going up but it reach the dead end at 7500 rpm due to the limit of the ECU .. can we use the e...

Anyway this clears eveything to me ... so now what ever is available either big or small port i can have have and make this kind of power ... and surely i will buy them cams and pistons ...

The reason i converted the SPs torque is to see the difference as they are not the same units that s ft lb and kg M ... wast it that the torque is what we call the pulling power? Correct me if im wrong ... so im seeing on the above graphs that even though they have the same horse power at the same r...

as I am looking at both graphs above the bigport has a more linear torque from 4700 rpm to 6900 rpm averaging 20 ft-lb which I think is very nice and looking at the graph of the small port and converting the KG-M of torque to FT-LBS, I found that the smallport only makes around 116 ft-lb of torque,,...

Here is a smallport dyno comparison of stock cams, poncams and then poncams with increased compression. http://i79.photobucket.com/albums/j143/oldeskewltoy/TomeiPoncamsdyno.jpg As you can see the poncams do give a notable gain in the top end. They do have a small loss up to about 4500. The loss is ...

sir yoshimitsuspeed ... id like to ask if it is WHP or CHP on the chart below?

is that a small port engine?

thanks so much ...

im from Philippines by the way ... so you're going to have a built 4ag just to sit in traffic? or if you're in the province maybe you'll hit 2nd gear before a scooter cuts you off. jk. imo get a stock 20v. keep it simple. its only traffic here in the cities, not in my case as I live in province ......

ive been reading this thread lately and its informative ... thanks to sir oldeskewltoy .....

how about this then?

ok I get it correct me if Im wrong,, I guess that the small port with the thicker and wider con rod is the small port 4AGZE ...

you are drastically over thinking stuff here man, just but a small port "red top" and leave it stock initially, It will be a decent enough increase over a 4af to keep you happy for a while maybe I am, its just that if im going to buy I would like to know the best one so that it would save...

here , I got this pictures of the connecting rods, https://encrypted-tbn2.gstatic.com/images?q=tbn:ANd9GcQ_G-dxgSEOrPiDTwoLASTlBlhoPEjpw4ImR8HBA5AyxxmhqH_5 https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcTvwx_yfCFeFwaAaWVP6Pw8xGVPdVCwlaGpLQ5OxJvRZ_3iETGa these pictures says that there are two ...

According to an old motorweek video the transverse bigport 4As were down in power because the intake manifold was compromised for packaging. If I remember correctly, 4A-F transmissions have a taller final drive than the 4A-G. There shouldn't be any problem bolting them up. When you say taller final...

one more thing ,, is it possible to use the current transmission of my 4AF engine to small port 4age? will it handle the power that the small port gives? ... im asking this because if it is possible then the money that I will be saving from the transmission will go to new aftermarket cams like the p...

I checked it at 4age wikipidea , there the small port is the one with 149 torque and the big port makes 131, so which is correct? this is what confuses me by phil bradshaw http://home.clear.net.nz/pages/phil.bradshaw/4AGE%20into%20RWD.htm in this link the earlier big port makes moe torque, while on ...

happy holidays guys, I have few additional questions here as I have read in some websites on the net the earlier bigport 4age bluetop is closer in power to the small port, 129 for blue top big port and 140 for small port, but the bigport mkes more torque than the small port 149 (bigport) vs 141 (sma...

thanks a lot sir..

guys, I know this is out of the topic, but do you have any soft copy or pdf copies of 4age manuals? if it is possible if you ever have can I have the copy of the manuals of all generations of 4age from the big port to the 20 valves, I just want to study them for future references ... if you can send...

I checked this link as posted on this thread.

im wondering why tomei only got 264/256 cams while kelford has different kinds of cams durations like 270 and 280 cams?
is tomei' limiting its cams to what the stock ECU and valves springs can handle?

Thanks for the link sir . I already saw it. So has any one here tried that racing cams from tomei and kelford? And what do you guys think about those claims that they have. So i guess that the tomei poncam 262 cam is the maximum cam that can be use with the stock ecu and stock valve springs? because...

are there any good after market racing cams for 4age blacktop? if there is, has anybody here tried that? whats the output? I know you are new and I feel like everyone has been pretty patient and helpful asking each and every one of your questions that show you have done absolutely no research yours...

kidsharingan - I apologize for not explaining further... jumping to conclusions. The best advice I can offer at this point in time, is for you to look for a quality machine shop. A shop who KNOWS what they are doing. Where do you live? that's ok sir, each one of us is entitled to say their opinions...

Thanks alot for your advices gurus ... i really appreciate it you having time replying to my noob questions.. now i know what i will do after i have my engine swap this comming year. Ill be posting my swap here after its done to thank you for everything.. more horse power

As much as possible if im going to want to have more power i dont like to touch the engine like reboring the cylinders or porting the heads ... its nice to know that there are things we can do to make more power without distroying the engine by porting or rebore jobs.. thanks again really???? :cry:...

Thanks again.. how about adjustable cam gears? Will it help in making more power? And how about changing the stock cam gears with bigger ones? As much as possible if im going to want to have more power i dont like to touch the engine like reboring the cylinders or porting the heads ... its nice to k...
