davenethel Posted March 18, 2009 Share Posted March 18, 2009 (edited) I'm looking for some input on swapping out the 4 cylinder, standard shift engine on our 1986 Dolphin for a V-6. I'm looking at a refurbished 1968 volkswagen ragtop bug to purchase and I want to tow it behind my motorhome. The 4 cylinder is not recommended for towing. Has anyone swapped out the 4 cylinder for a six? Were there any problems? Edited March 18, 2009 by davenethel Quote Link to comment Share on other sites More sharing options...
DRG567 Posted March 18, 2009 Share Posted March 18, 2009 I THOUGHT these units where not made to tow Quote Link to comment Share on other sites More sharing options...
Maineah Posted March 18, 2009 Share Posted March 18, 2009 Major project. No matter what the engine it would not be safe to tow any thing that weight you'll never stop it, handling issues, frame issues not a good plan. Quote Link to comment Share on other sites More sharing options...
WME Posted March 19, 2009 Share Posted March 19, 2009 Even if you changed to the GM V-6 4.3l to get enough power to tow, you don't have enough brakes to stop both cars. Quote Link to comment Share on other sites More sharing options...
futar Posted March 19, 2009 Share Posted March 19, 2009 As I stated elsewhere, the ring gear in the rear axle can get ground down from too much stress. There probably are other parts that are at their maximum load. It is unlawful in all states to tow vehicles without a remote braking system like the brake buddy. Some states allow you to tow very, very light trailers without remote braking. Quote Link to comment Share on other sites More sharing options...
WME Posted March 20, 2009 Share Posted March 20, 2009 Most states have NO law on Towd brakes or they only apply if the towd weighs more that 3000lb. Quote Link to comment Share on other sites More sharing options...
comfun1 Posted March 20, 2009 Share Posted March 20, 2009 I have been towing two four wheelers through the mountain passes in Colorado and New Mexico with my '86 Escaper 4cyl 4sp no problems other than a bit slow. Quote Link to comment Share on other sites More sharing options...
T.A.J. Posted March 21, 2009 Share Posted March 21, 2009 I've got an '84 Dolphin with the 22r 4 cyl., 4speed and the couple I bought it from towed an older VW bug and hauled a Honda 90 on the rear rack. She said it would pull at 60mph on flat without probs. I looked closely at the frame and mounting of the receiver hitch when I bought it. I see know stress or damage to the original frame. If you choose to tow, common sense and driver caution is the key!!! Good luck, have fun, and smile. Quote Link to comment Share on other sites More sharing options...

I pull a hay wagon with my 97 Tacoma the truck it is rated 3,500# tow weight the hay wagon goes 7,000+ it will pull it but it won’t stop it so I drive d---- slow. The Toyota MH is right at max with every thing drive train included it is not safe to pull any kind of weight with them there is just not enough brakes and you have an extra two feet or so of added on frame that multiplies the tongue weight and stresses the frame extension factory recommended tow weight 0#. I know it’s cool to take your toys with you but it not a good ideal. Quote Link to comment Share on other sites More sharing options...

futar Posted March 23, 2009 Share Posted March 23, 2009 Here's a link to the towing laws. http://www.brakebuddy.com/Towing-Laws The remote brake requirement is as low as 1,000 pounds. Quote Link to comment Share on other sites More sharing options...
davenethel Posted March 23, 2009 Author Share Posted March 23, 2009 Thanks so much for all your comebacks. Looks like I may be cycling instead of driving for transportation. Thanks again and Happy Motoring! Quote Link to comment Share on other sites More sharing options...
Mikesta Posted March 24, 2009 Share Posted March 24, 2009 Thanks so much for all your comebacks.Looks like I may be cycling instead of driving for transportation. Thanks again and Happy Motoring! Dave, If you have money, you can tow. You need money though and if you have money you wouldn't be driving a toyota. However it can be done with the right inteligence, upgrades etc. I'd go diesel though and brake assist is a must. You won't be able to to a Unimog, but you could tow a car. Money my friend.

I disagree with your statement. Lack of money and Toyotas do not necessarily go hand in hand. There are people with money that still choose to drive a Toyota. It might have something to do with not wanting to be like everyone else in RV Land. Quote Link to comment Share on other sites More sharing options...
nibs Posted March 26, 2009 Share Posted March 26, 2009 Towing a car using an A frame puts no tongue weight on the tow vehicle. But the weight of the toad is a real concern, we are on the final leg of a 4,000 mile trip towing a 1,000# trailer with no brakes. We have been through mountain passes over 10,000' with no probs. BUT, I have tons of experience with logging trucks and big vehicles, and going down hill, I use the engine to keep the speed down, sometimes leaving the truck in 1st gear if the downhill is steep.......Tony Quote Link to comment Share on other sites More sharing options...

It's a big help. I have experience as well driving and towing. It makes sence what you say about using lower gears to slow down the vehicle. I appreciate your feedback.

bajadulce Posted March 30, 2009 Share Posted March 30, 2009 I'm looking for some input on swapping out the 4 cylinder, standard shift engine on our 1986 Dolphin for a V-6. ...any problems?Tons.. engine swap @ YotatechI'm looking at a refurbished 1968 volkswagen ragtop bug to purchase and I want to tow it behind my motorhome.ragtop = convertible? or the sliding ragtop? They make those in 68? Bugs are pretty light, but prob not light enough. A diesel might be able to do it as Mikesta suggested. I read about a guy @ toyotadiesel.com that claims he tows this huge boat down to the boat launch. I think the boat launch is about 2 miles from his house if I remember. Oh and it's in Tahoe at high altitude as well. It too was an engine swap. I think it was an LT not the KZ or whatever the blasted motors are called. Somewhere in the Swap section there as well.How about some Scooters!? Or maybe an ATC? Those can get kind of heavy too I suppose. Maybe a cabover on a pickup w/ hydraulic lifts/stands? I'd show you my own hack project for the park-and-go setup, but its still quite a work-in-progress. Quote Link to comment Share on other sites More sharing options...
