I'd like to know what some of the members are running for a type iv. Please answer the following questions:
1. What is the stroke, bore, and CC's of the engine? 2. If the engine is stroked over 71mm what case work was needed? 3. What cam are you running? 4. If using carbs/EFI, what is the setup? 5. What's the HP, or do you feel the engine has good torque/HP for the setup you have? 6. Comments on anything else... Hine62 |

its a mystery to me Group: Members Posts: 1,828 Joined: 17-March 03 From: Marriottsville, MD Member No.: 434 Region Association: MidAtlantic Region |
103 bore, 80mm stroke, reduced base circle cam, relieved case and big end of the rods...had to machine case for the cylinders, ordered heads to fit the larger cylinders..fuel injected megasquirt...horsepower? no idea, but pulls a lot better than stock! 150+ or so..torque to match. I set this up to be a torque monster..so far it is. I need a lot more tire as I light them up way too easily. it makes autocross a lot of fun.

I have about the same engine as Herb in my '67 bug, look at my signature...torque monster is an understatement.

I used the 66mm crank and went with 96mm pistons and cylinders from KB and AA. Bought from the type 4 store, so they have Hasting rings. Got a 9550 cam from Jake... The one that runs best with FI, I am working from memory here. I do have OEM L-Jet injection. just under 8 on my CR. I added 911 rockers with swivel feet. went thru the whole push rod measuring and fabrication thing too. HAM re-worked my heads with new valves, etc.... He opened the ports and increased the valve size to the OEM 2 liter size valves. I ditched the points and condenser and got a little HOT START module from eBay. Stock '75 exhaust for now. I did adjust the AFM gear about 11 teeth to account for the increased displacement. Not sure about the HP, maybe I'll check it one day. Clark |

Great info! I'd post mine but it's stock 1.8 with dual 34s and it needs more power...
Anyone else want to post their setup? Hine62 |

I'm running a stock 2.0 D-jet. 95HP, 94 x 71 B/S. While I may go bigger when this engine gets tired, I must say I'm impressed with it. It pulls hard in all gears, gets 27MPG and is very reliable (after working out a few bugs).
What are your plans (and budget) for the car? I would base your engine choice on that. (IMG:style_emoticons/default/beerchug.gif) |

Stock '71 - 1.7 in a stock car. Minimal horsepower, barely enough torque. Driving it makes me smile (IMG:style_emoticons/default/biggrin.gif)

2056 w AA cylinders and KB pistons. 9550 cam, Ljet, 9:1 cr. SS heat exchangers, Leistritz factory muffler.
Runs very well after cold start up, which requires throttle control to keep it running. (IMG:style_emoticons/default/mad.gif) A minute or so later, all's good. (IMG:style_emoticons/default/smile.gif) |

Home rebuild of a stock '76, FI 2L.
My crank was bent so I bought a counterweighted stock crank from Rimco and balanced the rods, flywheel, etc. I think the counterweighted crank is smoother @highway speeds than my stock 1.7 and a '70 bug I have. AA flat top piston, cyl assemblies. The stock pistons were dished so the flat tops give a little more compression. AA parts need to be measured and matched... HAM rebuilt my heads and I bought a Raby 9550 cam kit. Used Jake's video to put it together (but remember the oil sump baffle..tray..thingy...) Pertronics II and coil. It has plenty of power for me and pulls nicely thru a near stop in 2nd gear. I get 30/35 mpg. Highway speeds of 75 -80. I've had it up to 125 indicated with stock/tall tires. My head temps run 275 to 325, sometimes 350 if there's a head wind. Oil temps are around 200 this summer with a cooler in the deck lid. I'm going to take it off this fall and see how it does. Rimco and HAM were good to work with and the Raby cam does everthing he says it does. The ignition hasn't failed yet. I can't wait to do another one. I'll try a 2056. Good luck |

My LE has it's original 2.0 engine using stock D-jet FI & cam, w/ OEM Mahle euro pistons & cylinders, Bursch tuned exhaust, K&N air filter & Pertronix ignition. Not a heavily modified engine but I'm guessing between 100-105 bhp. Smooth, torquie & fun (IMG:style_emoticons/default/smile.gif)

Lots of great information. It looks like the 2056 is the most performed up grade. With a 71mm crank the case doesn't need to be machined.
@Dtjaden Did you install the megasquirt? How much did you spend? hine62 |
