hook it up with a 1mzfe and i'll throw it in my celica and try it out :P

I doubt it was alloy, there is a lot of design that goes into it as well. The TRD 4A cranks suck badly, too, but not much outside Honduh seems to have a 10K rpm reliable factory crank. Shame they don't rotate the same as other engines, they would make great petite RWD mills.

Yeah, but I4's have their places... underpowered cone chasing cars, and lightweight 7 type open wheeled vehicles that don't need a lot of power. It's also cool that some of the I4's are so robust.

I dont think there is enough info here, I would really want to know what the project was before I decided on a engine. I still think the b series are great, maybe not in stock form anything you can through rods and pistons at and run 450 whp all day long on a pump gas with a stock trans and have it bullit proof is good with me BUT if were going to be building a 69 camaro........................you see my point.

MZ's are good if you're on an extreme weight diet. They weigh 340-349lbs with coolant ready to rock.
They also are not nearly as strong as the 420lb VZ's that came before them. You can take the VZ's way out over 500bhp with no major work. Headgasket swap & staying on the ball with tuning.

10000rpm cranks? IDK I'm sure some of the newer Toyota cranks could. I can't think of a weak crank they've made since the 80's. In the early/mid 90's they finished phasing out all of their older construction types. They moved them all to tool steel during that time, or killed off the engine families that used them. Woot woot
Yes i4's have their place, but ya gotta see my point. If the typical 200-240lb i4 will fit, a 340-400lb v6 will fit better with way more power.




hehehehe rawr keeps up with it. It's common for a BPU'ed 3s-gte MR2's to run around 14.2s 1/4m times. You throw a bone stone 3.0L 1mz-fe v6 in the car & they run 14.5 all day. Way stronger until the end of the track. You get on a real racing circuit you can lap the 3s-gte cars all day long with roughly 100bhp less from having a much mroe accessable powerband.
And when you get to the point of having to start upsizing the turbo's for the i4's to compete. They just get flogged for not having a powerband against slapping a turbo on the 6 cylinder muwahahaha
Ya I mean, I think it's cool there have been some i4's floating around for the last 15 years that can put out 300-350bhp'ish daily driven. Some of them dyno queening it up to 450bhp. (3s-gte, 4g63, etc.) btw 4g63's are pieces of royal ----. I'd rather close the deck on a Honda engine & throw new pistons & rods in there than run one of those son's of bitches. 3s-gte's are not 450bhp daily driveable engines (none of them are...) But atleast they're reliable. The only downside to 3s-gte's is they can be alittle leak-happy, but ---- it. Full gasket kit from Toyota is around $80-120usd.








Anyone else wanna second anyone chosing:

• Honda D series
  Nissan SR20
  Nissan RB26
  Nissan VG30
  Toyota 4AGE
  Toyota 1JZ
  Mitsubishi 4G63
  Mitsubishi 6G72
  Subaru EJ20

are dumb for picking engines where their are better engines in that particular class? You know... If you're picking an engine to START a project with. Pick the winners...


And ya I'd have taken a B-anything over that piece of ---- 4a I use to have. My god... Some engines just do not desirve their reputation AT ALL.

accordepicenter

i truely believe that sr20s and RB26s are hyped about also, both seem very overrated

vg30dett is a pretty nice engine. Not wonderful, ive blown two. but a nice healthy one puts down a good amount of power and torque.

i'm just trying to get some opinions on what engines are good and why. project doesn't matter really, i'd prefer opinions on rear wheel drive engines but i included fwd engines because they can be applied to some creative projects as well. i guess i should have added some criteria, maybe like availability, price, potential for good power to weight ratio, aftermarket support... whatever comes to people's minds for why they would choose one particular engine as a great starting point. and lets get some more damn votes here, with over 300 views and only 81 votes, that's less than 30% c'mon people!

if I was to start a new project right now it would be a 1969ish austin mini, stripped with a turbo hyabussa(rear mounted), rear wheel drive SUPER LIGHT WIEGHT, chain drive, solid rear axle, 10 inch tires, 4 pot disc brakes............................. ultra fast, light wieght street legal gocart. Flat black, lowered, small old school flares, fairly stock looking.

SR20det. With a good head, stock bottom end and good fuel management, you can have 500hp daily drivin. 4cyl, engine doesnt weigh a ton (the block can be shipped through the dam post office for dam sakes) parts are becomming very abundant...

4g63.... been working on making it great for years..... those things are awesome
