I'll have an o2j with some close gears for sale soon. Putting a tdi 'box in mine. Got sick of there being no traction in 1st

rockinveedubs · « **Reply #2 on:** July 20, 2011, 09:41:42 PM »

if it comes with everything for the swap id do it...if the tranny isnt a rediculous price. i dont want to hunt for parts to convert. whats the price? PM me

rockinveedubs · « **Reply #3 on:** August 20, 2011, 08:39:23 PM »

So for transmission i want an 02a and brake master and booster from a b3 passat. I keep hearing different things about how much is involved. Needing a clutch cable from a honda crx and some other stuff from a eurovan... i think thats all cause people half ass it. If i use everything from a passat all id need is conversion mounts. Am i wrong?

If I can make a comment about side exit exhaust. I had one at one point in the Scirocco, and (It's been a long time since I have looked under a rabbit) but the only way to do side dump without putting your exhaust right on fuel lines, is to dump right between the driver side door, and the read d-side tire, and there is not really any room for any decent silencing muffler, and I will guarantee noise headache's with the exhaust being right there. That is just my experience though.

rockinveedubs · « **Reply #5 on:** August 26, 2011, 08:48:01 AM »

Haha dont i know. Ive run side exit with a 2 in exhaust with my JH! I loved it. But yes... very loud. I may get something to quiet it down. Not sure what. May even just get a TT exhaust...

But ive got all my tranny stuff from UPAP! Transmission, shifter, cables, slave cylinder, flywheel, master cylinder, brake booster pedal assembly and engine harness. Got it all pretty cheap. Now i need to build my 9a...

rotundapig · « **Reply #6 on:** August 26, 2011, 09:18:12 AM »

side exit exhaust on my rabbit was fun, but very loud. Eventually got ticketed.

rockinveedubs · « **Reply #7 on:** August 27, 2011, 06:42:33 PM »

Very! Does anyone prefer a company to buy 9a rebuild parts? Headgaskets, head studs, engibe seals... etc

rockinveedubs · « **Reply #8 on:** August 27, 2011, 06:52:06 PM »

Im aiming for building the motor so i can boost it later. Any suggestions on what i should improve over just the building the motor factory spec?

0dd_j0b · « **Reply #9 on:** August 28, 2011, 05:09:12 AM »

gaskets and seals and such you can go to GAP.com or bapgeon, something like that.

rockinveedubs · « **Reply #10 on:** August 28, 2011, 08:56:54 AM »

Any name brands i should look for? Bap likes to just hand you whatever they have.

0dd_j0b · « **Reply #11 on:** August 28, 2011, 11:16:17 AM »

Not really, I haven't had any problems with any gasket sets from GAP.com.

They have head gasket kits includes head gasket, exhaust mani gasket, valve cover gaskets and such.

But yeah, I have not had any problems, and have not heard of anyone else having problems.

rockinveedubs · « **Reply #12 on:** August 28, 2011, 11:46:20 AM »

Sweet thanks man. Any suggetions for building the motor for boost later?

0dd_j0b · « **Reply #13 on:** August 28, 2011, 12:50:01 PM »

Not really, I'm not very familiar with anything turbo building. When I had aspirations for turbo I looked around for some info and, (please correct if I'm wrong) you are looking for a 8.5:1 compression ratio, not sure what the 9a starts at. Also what fuel management system you are going for, whether Digifant, CIS (please no) or megasquirt, From the plethora of turbo build threads on the whoretex, most people go the megasquirt route for the simplicity of tuning...or something like that. As far as the parts like valves, pistons etc. etc. I am not going to venture into that dark room, cause I honestly have no knowledge, and do not want to make myself look like a tool by talking about something I have absolutely no idea what I'm talking about.

Looking forward for the rest of this build thread, good luck on the build.

Thanks man. Does GAP stand for something? Im unable to find it

rockinveedubs · « **Reply #16 on:** September 13, 2011, 02:17:06 PM »

So my plans for the build have been changed. I dint want CIS basic... i will use it but as long as the car is getting all the best treatment id like to use a different route... megasquirt maybe? Im building the car to withstand turbo when that time comes and id like to be able to just bolt on turbo and tune the motor for it. Could anyone give me the basics of what would be needed for some sort of stand alone system? I know I'll have to build my own grom random parts. But i want it done right with good stuff. I dont want to have to back track and redo something.

DIYautotune.co m <--- megasquirt needs\

ALso talk to Chris (Smokestack(I think)) and Theron (Random_Task) with everything you need to know, I'm pretty sure there are a few others on here that know how to work on it, but I'm not sure who they are.

rockinveedubs · « **Reply #18 on:** September 14, 2011, 11:57:26 AM »

How much does a mega squirt system usually cost? Ive seen from $1200 to $1500

rotundapig · « **Reply #19 on:** September 14, 2011, 04:41:09 PM »

Hell no! Build it yourself for like $150 and then you'll get a better idea of how it works:

I know I haven't been around in a while..but the advice for your turbo build...You might want to drop the 9a block and go with early ABA from what I gather they are forged bottom end...great for boosting...if not then I would get at the very least forged pistons for the 9a...if you just do a standard rebuilt on one the compression ratio is to high (somewhere around 10 to 10.5 to 1)and if you are going to boost the 9a of course get rid of the 2.0 head and find a 1.8 head(better flow..)
When I had my mk2 golf gt I did ALOT of research on how to build a 16v for boost..And I know everyone puts down CIS because you can't tune it easily...but with the right parts(mostly volvo 240 turbo parts)you can get a CIS turbo'd 16v to scream...

Anyway thats my 4 cents I guess...and just so you know I am not some ID10T(idiot)I was an auto mech for 20 years and have worked on just about evey make and model of car you can think of...with the exception of say a ferarri or bently(well I did do the brakes on one once)...

I'm prob gonna do a ABA in my mk1 and then S/C or Turbo it later down the road.... A shop here in AZ has pre-built harnesses for this swap built allready...So i'tll be a quick and easy swap...Unless i go the TDI route not sure yet...

Thanks. And im not sure but from ehat ive heard the later 9a internals are forged and have oil squirters. My motor is a 92. And im not sure how the 1.8 16v head flows any better... any conclusions as to how this is?

A2GTUS · « **Reply #23 on:** September 14, 2011, 08:33:54 PM »

From what I understand the 1.8 16v head flows better because it doesn't have to hang a hard right turn on the intake side where as the 2.0 16v does look on whoretex..ther e is a lot of info on it there...as far as the forged bottom end of a late 9a you may be right but you will still need to get lower compression pistons to get to the 8.5 to 1 you want for boost...thats the reason the 9a is such a good NA engine because the 10.3 to 1 compression ratio gives it a 134hp ratting...

Good Luck with it and if I can help in anyway just let me know...

rockinveedubs · « **Reply #24 on:** September 15, 2011, 08:11:26 PM »

Thanks. I appreciate that. But a new idea has come to mind... my 84 4dr was fun to just cruise around with the 1.8 JH... i figure i can put the car back together with another motor, freshen the suspension and brakes up and have my first car back as my daily... but i still want a 16v. I have another 16v in line for it with less than 32,xxx miles on it out of an 87 gti. All my plans for the 4dr are being put on hold i think till i can build my 2.0 16v and do more research on what fuel management system to use... and id like a 2 dr for all the goodies.
Soooooo...
New plan is do a 1.8 16v swap with my CIS basic or the fuel management the motor is coming with
Raceland header
Rebuild brakes
Rebuild suspension with my sportline springs i have sitting around
Clean some stuff up and respawn my 1st car and my daily driver

Im haveing trouble remembering what the fuel management system used in 87 was... should i use it?
