Hi guys after some info, I need to decide what motor to put into the EK wagon project, it will be a daily driver, and tow a trailer most days (6x4) then one or two trips away each year for holidays with a caravan,
It will be running a trimatic and 3.08 course spline slippery diff, but i have had conflicting stories as to what motor to use red 186, red 202, or blue 202??
Can anyone shed some light or suggestions as to the best move here? I would really appreciate the help

I'd use a red 202 (extra torque to tow the van and no pollution requirements if it is an HQ block) with blue 202 crank and a Black VK Injection head with the VK injection.

If you plan to build a fresh motor use a 179 HP block, bore it to 186 (if you start with a 186 or 202 block then bore it you could run into cooling issues when towing due to thin bores - 179 hp block is the same as a 186 just not bored as far to start wit

I built a drag motor several years ago and was considering the hp block as the candidate. After this same discussion we decided to settle it once and for all and put some effort into our conclusion. At my disposal was the Metrology Lab at Mitsubishi where

If you are going to modify an engine for extra hp, there is absolutely no doubt that you should use a early 202 blue motor with an EFI black motor head, or an aftermarket head. You are already in front with a later model block, 12 port head and the extra

Hi Guys.

I can't agree with this notion that the newer or later blocks are 'softer' than earlier versions.

I've run an automotive workshop for nearly 30 years & have been in the industry for over 35 years. The one thing that I've noted over time is

Well i would have to bow to Terry's experience but I have stripped about 5 blue or black motors and every one of them had broken rings and/or piston lands.

does it have to be an old six?
what about a Buick V6
or a rodeo V6?
stock standard they will tow your caravan without breaking a sweat.
i know some people will say "there crap motors"
but mine did over 500,000k's, 300,000 k's was with the dreaded VN

Hi Guys,
Sorry for bringing this up again, but I too have an EK wagon project the same as HQLDEN originally posted. And basically from what I can gather with Motor-options v $$, a few things have come up.

$ The Scrooge Option = 149 (is under the 15% m

Hmmm,

Bugger,

This this would mean the best (Yobo) upgrade from a 138 would be a 186. Unless Collapsible Steer was fitted (then go 202).
Would machining the 202 Crank cost or weaken it too much ?
Do the Blue/Black Conrods interchange 186 ?
And if
