I need homework.... T5 me.

[ecksrash]

Hi, I've wanted to do an oxy build for several years and now I'm going to request as much knowledge as I can get. I want to go big. I am willing to take risks, but educated ones. Ive built a few aircooled engines that are stout. I'm looking to install this engine in a full weight ghia and have it live on the street. Not an everyday driver by any means, but a weekend ground pounder.

Enlighten me regarding proven combos and things to look for when buying a core. Who is making parts to adapt and solutions to common problems. I've read up on some of the saved threads here and see that the cooling is able to be adapted from T1 shrouding. I am aware that the MV case is more desireable than the 1.9 cases. What are you doing about cylinders and heads that are proven? What are the issues with bearings and what is the best choice for a crank?

I look forward to your input and knowledge. DS

the information you are seeking is all over this forum , have you checked out the stickies ?

your complete lack of engagement will probably get you no answers what so ever .

i have only one tip for you. whatever your budget is . tripple it and you will be in the ballpark costwise, these engines aren´t cheap to tinker around with.

Finding an wbx core today in good nick isn´t an easy task . myself i found a complete running engine from a rallycross car for good money but that was just pure luck

Thanks for the reply, I have read the stickies and have gotten good info. Thanks for that reccomendation.

May I ask what some things to look for and be aware of when looking for a core? What are common problems that would make a core unacceptable?

I have helped a number of builders with there oxyboxer engine, as someone else has posted this is not a cheap build it can and will cost a lot more than a T-1 case build. Things to look for. 1st buy a 2.1 core here in the US its a MV number below the breather tower on the sides of the sump of the block last 3 numbers & letter 101B 102B without the B its a 1.9 block. The 2.1 block has a 76mm crank inside so you get a stroker crank if you buy that core engine. Watch out for engine cores that have ran out of oil or coolant, its hard to tell from the outside so ask the place you buy the core from if the block and crank are junk will they give you your $$ back. I will not build off a 1.9 block. The 3 pc. flywheel brg set up in the 2.1 is the best thrust shim brg set up VW has ever made ( wish they would have thought of that back in the 60s) all the load brgs are steel backed. There is a lot of talk about the T-1 engines center main being steel backed the 2.1 has all the mains steel back but the pulley brg. Don't even think of using a T-1 crank in a oxy boxer build as you will have to go back to the old style thrust set up. If you want to email me or talk with me I will give you a run down of what you need to do and some of the costs to do it. Again its not cheap. I have a lot of info. on my web site. www.rockyjennings.com Thanks Rocky

Thanks for the pointers Rocky. What if I wanted to go with a big stroke? Can the 76mm crank be welded and ground like a type 1 crank? I realize that there can be clearance issues with the cam and crank when big strokes are in these engines. What are the solutions?

[riseabove]

Apart from the obvious obstacles of cost and so on the engine you end up with will be MUCH more capable than if you build from type1 block of any kind.

Me and my friend is in the process of building a 2.1 daily driver engine based on the a wbx dj block. will keep the hydraulic cam in it and run fully ported 043 heads without going big on valves and stuff . hope to ut out 100 reliable whp and so far it looks like we are going to get to this goal EASILY.

[ecksrash]

How big can I go with a 1.9 case? I'm sure the 103mm cylinders are doable, but what about stroke? I think I read that the MV cases allow for more stroke, and I honestly want to build a beast.

[ecksrash]

YAWN....

Here are a few pictures of the #1 brg with thrust shims in a 2.1 block

All you need is a B block, 2.1 or 1.9 is irrelevant, they are the same, late 1.9's are B also but may be rare Stateside.

double bubble.

Something just came to mind here are these thrust sims reusable.

[AMBROSIA]

I've just had to replace my thrust shim on my 2.1.
I originally built the engine reusing the original thrust shim but new shims.
End float was set at 4 thou.
Recently the engine started producing bad vibrations and upon checking there was excessive end float.
The removed thrust shim was clearly squished but the other shims where undamaged.
The replacement fitted with the original shims returned the end float exactly back to 4 thou.
So based on this I will personally never reuse another thrust shim.

Thanks ambrosia for the advice i will change mine once i open the block.
