I didn't realize those Molnar 40-20 rods required modifying the block. I had bought a set years ago from Orion, but I never used them. Not always...

a 7AGE is something that I was considering, especially as the 1800cc engine get a 100lbs weight break. I'm currious to what the real potential, I'm following the 7AGE tread and looking for some Dyno figures but I'm not finding anything concrete. Cheers, Fred As with a 4AG... all it takes is money. ...

a nice 3 angle valve job... and back cut intake valve......

OP - do you have a dyno plot?? Also you may need to change the car some as the 4AG is a taller engine then the 3T. If you make more room, you also open up the possibility of the 7AGE (7AF block, with 4AG head) As far as power potential for a silvertop... it is similar to the Blacktop, easy enough to...

On a related note. For "3rd party" cast pistons, which don't already have a coating (whatever it is that was done on OEM 10.3:1 pistons), would having the domes ceramic coated help when pushing for higher-than-stock HP? I'm guessing it at least helps with heat dispersion and so prevents h...

There isn't a horsepower limit... there is a tuning limit. There is a "flaw" with all the n/a pistons for the 4AGE... the 2nd compression ring rests on ring land that is not well supported (piston on right in photo) http://ost.ebeans.ch/albums/userpics/10005/ring_land_support_slot_vs_holes...

and the internals.......

I guess that was my question. Will there be any potential engine damage for driving around with a vehicle that is not properly tuned (not for very long), but am assuming at least 100-200 miles before the ITB kit and the standalone ECU is installed. being 100% honest... I don't know...odds are there...

Can the stock JDM 16v ECU run the car ok ? "Ok" - a lot would depend on what ok actually means... but it should run on stock JDM management, how well is another story... The stock computer uses a whole bunch of different parameters(stock engine), you have changed many of those... so, it s...

look in your own area for powder coating, and show them the photos.

a few pointers... Dont get them coated on the inside, and make sure breather is taped closed during coating

Breath taken sir. So question for you then, to simplify everything. What do you think about this option: Red top pistons MRP stainless steel valves - https://www.mrpltd.co.nz/product/4age-16v-stainless-steel-valves-0-5mm/ Stem seals MRP connecting rods - https://www.mrpltd.co.nz/product/4age-billet...

I probably put more things for generic engine rebuild stuff on things that I decided to not go with. Do you have any recommendations? Here is my compiled list so far... Pistons: ⋅  4AG Red Top High Compression Pistons, 10.3:1 : $530NZD -> $342 USD ⋅  Brian Crower 12.0:1 Pistors ...

Sorry this is my first appearance... I typically avoid ITB threads... they aren't often needed(my 140+ whp smallport runs just fine on a single T/B), and if not done correctly can and often does cause operational issues do to poor set-up (mechanical, as well as from a management POV) I am absolutely...

what does "tumbling" the head consist of? Is it similar to tumbling bullet casings? Not sure (tumbling bullet casings...???) What "tumbling" means in this case is they have a large tool - it consists of a large cabinet, with a rotisserie that you strap the head too. The cabinet ...
