4age 16 - full engine assembly video stop motion

Postby mr2mk1hero » Fri Aug 26, 2016 2:46 am

This video and engine is a product of two years of collecting parts, learning things I previously knew nothing about, saving money and then finally putting it all together.

The particular engine assembled in this video is a 4age 16v bigport from my 1987 MR2 mk1. The engine has been lightly modded with some technotoytuning adjustable cam pulleys, HKS valve springs, mild catcams camshafts (2x 7105136 exhaust cams, with 8.0mm of lift and 244 degress of duration). It also has domed 4age smallport pistons and a very mild head and block cut, leading to a final compression ratio of about 10.4:1. The block has been bored 0.5mm and oversized cast pistons and rings fitted.

This is a street build and goal was to give the engine a small increase in power and make the engine more lively and exciting, but also keep it as reliable as possible. This is why the engine has remained non-interference. The crankshaft, flywheel, clutch pressure plate, pistons and conrods have all been balanced to ensure the engine revs as smooth as possible and copes well with high-rpm.

Here's the more important stuff listed:
Crank bearings: OEM
conrod bearings: OEM
conrod bolts: ARP
Head bolts: OEM
Main cap bolts: OEM
Head gasket: OEM
Cams: Catcams 8.0 lift, 244 duration
Cam pulleys: techno toy tuning
Valve springs: HKS
Flywheel: oem blacktop
Clutch: Aisin
All gaskets: OEM


All of the parts received one or more combinations of the following: cleaning, blasting, galvanisation, painting.

I hope you guys will enjoys watching!

Very cool!

Do you know what kind of power you're getting at the crank and to the wheels? I imagine a little more than a stock smallport.

Thanks, I'm glad you like it.

I have yet to connect everything and fire it up. But you are right I expect 130-140hp.
I forgot to mention the head was also mildly ported by me so that should help a bit too.

Hi,

Are you sure that's a small port head? There is no oil drain on the head on the LHS...

Not a smallport, someone asked that by mistake I believe. This is a 16v bigport.
