4AGE 20v bottom end assembly

[@irabrook]

Hey thanks for the quality info I'm going to be building a 16 valve for my ae86. I went with supertech 11:1 pistons and poncams

[@4AGEEDGarage]

Welcome. Nice that should go well in the ae86

[@СергейМусин-л8ы]

very very cool you build 4age

[@4AGEEDGarage]

Thanks 😊

Brother im from sri lanka , i need a idea from you, i have carina Gt car comes with 4 age 20 valve silver top engine. Car have a problem with high rpm in idling. Cold start 2000 and when its become warm rpm will be 1500. But when im disconnect AICV SENSOR cupler rpm will become normal.

[@marlborobunnie]

where did you get the engine manual ?

[@4AGEEDGarage]

Hey, I have a Haynes Toyota Corolla manual with 4age engine and also a factory Toyota one on my computer. If your a member of my 4AGE~4AGZE~4AGTE ( english) page on Facebook, search the files part of the Facebook page and I have uploaded the manuals on there also which you can download

[@mrwetwild6930]

What’s your facebook account name bro ?? I’m trying to get a manual to help with my build

[@valterbeicinha9633]

how did you got the interior bottom part of the engine cleaned?

[@4AGEEDGarage]

Hi, are you talking about the sump/oil pan? I scrubbed it out by hand with a brush with degreaser, then flushed out with brake cleaner to remove the residue. Engine block was acid dipped when machine work was done. Hope that helps

[@mtaufanrp26]

What pistons did you use? Sorry I can’t hear you clearly.

[@4AGEEDGarage]

Hey, OEM .5 oversized 20v Blacktop pistons from MRP

[@erwinschmied]

did the machine shop have a torque plate?

[@4AGEEDGarage]

Torque plate to do what?

[@erwinschmied]

@@4AGEEDGarage when they were honing the cylinders

[@4AGEEDGarage]

@@erwinschmied I don't know their process. I took it to a well known professional machine shop in town near my work so they would have used the correct procedures as they do this every day for many different engine configurations.

[@MultiDasitha]

This is very usefull. thank you very much for your videos!

[@4AGEEDGarage]

Your welcome

[@balfourrankine72]

I'm in Canada I am trying to find my chrome shop for my 20 20 valve 4AGE blacktop crankshafts I love this video send me a link where I could get this

[@James_Maguire]

Hey just a quick question. Do you think I would need forged rods with 12.5:1 compression 4age 20v silvertop

[@4AGEEDGarage]

Hey James, probably would be fine but I'd do a little more research. Ideally with that high compression the engine would benefit from having lighter/stronger rods I would imagine.

[@deanarmst7449]

how easy should my engine be able to turn with just the crank and the pistons installed? also how much noise should it make?

[@4AGEEDGarage]

Should be a medium about of resistance due to the weight of everything but not hard. Shouldn't be much noise at all besides piston rings going up the bore. Best not to rotate it too much though

[@rankinezack6386]

Where did you get the crankshaft to buy I need a 4age 20v blacktop crankshaft

[@4AGEEDGarage]

It is my original crankshaft I sent to machine shop.

[@rankinezack6386]

@@4AGEEDGarage 👍

[@wannabecarguy]

I work with the silvertop. Aren't the the crankshafts similar? The 16v had a larger journal variant which was used in the 20v silver and black?

[@erwinschmied]

​@@4AGEEDGaragewhat did you have the machine shop do plus was it necessary?

[@4AGEEDGarage]

@@erwinschmied I had the bores the block and head acid dipped, frost plugs removed, bores .5 oversized and honed, crank journals polished, bottom end assembly balanced (crank, pulleys, flywheel and clutch plate), journals measured, ring gaps for pistons, block and head skimmed, valve seats re cut on exhaust ports and valves machined the suit, think that is about it. Just over $1200 NZD

[@ericohman]

Do you use regular 2 component single stage car paint on the block? Does it handle temp?

[@4AGEEDGarage]

Just normal car paint can be used, paint I used was g30 black which is an industrial strength satin black. Just ensure a good etch primer is used. Block is still looking good

[@fodenpetersen8829]

If you don't mind me asking what did it cost to build this motor including the head?

[@4AGEEDGarage]

Yeah thats fine. The whole job including parts, machining, buying the tools and accessories for head porting cost just over $5100 NZD plus my time. So I would hate to imagine the costs if a shop was to do the same thing. There are things I could have done cheaper like silvertop rods, oem headstuds, reuse oil pump but wanted to do it once and do it right.

[@cravendelossantos]

bro, can you reply back the part number of NPR piston rings please? Thanks!

[@4AGEEDGarage]

Don't have the number handy sorry and didn't take photos. This is the link for them and where I got mine from. They came with the pistons. www.mrpltd.co.nz/product/4age-20v-piston-rings/

[@cravendelossantos]

@@4AGEEDGarage many thanks :)

[@anthonywendt5834]

whats that ornge thing inside the oil pump inlet? assembly lube?

[@4AGEEDGarage]

Yeah, its when its pulled appart by SQ Engineering to do the internal porting, they pack with assembly lube to protect it for first initial start up.

[@anthonywendt5834]

@@4AGEEDGarage oh nice. I got nervous for ya thought it looked like a paper towel or something.

[@decmac3698]

Hi just wondering what manual you have

[@4AGEEDGarage]

Hey, I was using a Haynes AE92 corolla manual for a few things and a Toyota factory manual for 20v Blacktop. Here is the main engine section of the manual I used which I uploaded to my 4age page a while back. Hopefully it works for you as you can download it as a pdf. m.facebook.com/groups/170268589651195/permalink/832975336713847/

[@BurtonDynamics]

What pistons did you use

[@4AGEEDGarage]

OEM 11:1 compression .5 oversized pistons sourced from MRP

[@anonamouz1006]

Where are you located mate? And who did your reconditioning/tuning?

[@4AGEEDGarage]

Hey, thanks for the comment. I'm located in Tauranga, New Zealand. I used a local engine reconditioning shop to do my machine work and balancing. Still stock ecu so no tuning required.

[@derwhalfisch]

Where in NZ are you, mate? Who was your engine machinist? Love your presentation, very slick and to the point.

[@4AGEEDGarage]

Hey mate, sorry I was away road tripping on holiday when you commented. Thanks! I'm located in Tauranga, how about yourself?

[@derwhalfisch]

@@4AGEEDGarage I'm in Auckland. I'm tossing up swapping a blacktop into my FX-GT vs taking it off the road for longer and just doing up its existing bigport. I'm feeling really torn haha

[@4AGEEDGarage]

@@derwhalfisch haha I know how you feel. I was in the same situation when my bigport spun a bearing. I looked at rebuilding the bigport but there wasn't going to be any powergains as such without spending more money beyond just a straight rebuild, sooo I opted for the blacktop because I thought for the same price as rebuilding the bigport, I could have a blacktop which has more power and itbs stock, however i still had to rebuild the blacktop in the end. Definitely love it now after alot of money spent. Hardest thing is finding a good condition blacktop without high km

[@25kmgb]

Excellent

[@balfourrankine72]

I like this video

Can someone help me to get a blacktop crankshaft for a 4AGE please
