Hi guys,

I know I've read something on this subject before, but can't seem to remember where. Any way, here's the question (subject says it all):
We're building an EP 1984 Jetta. What would be the best 1.8L 8V solid lifter motor (to start building a race motor from)?

Thanks,

Get a JH motor from an A1 GTI or a Scirocco (also some Cabbys)

Thanks Bill. Do you know if an HT motor has hydraulic or solid lifters. I have a line on one with a little over 100k miles on it, also can pick up a JH for the same $, but have to remove it from the car. The guy with the HT motor says it's a solid head and it came out of a 1984 GTI.

Thanks,

Alex,

If it's an HT, it didn't come out of an '84 GTI, at least it wasn't the original motor. I believe the HT motor was used in the late 8v Sciroccos, and that it had hydraulic lifters. I think it's essentially the same as an RD motor. Go w/ the JH, or at least get a solid lifter head.

Thanks again Bill. I went to see the HT motor and the guy still swore it was a solid lifter head, so we removed the valve cover and sure enough it was a hydraulic head. The engine looked good though, so we might buy it and search for a solid head. What's the best solid lifter, big valve head to buy (non air shroud)? Does anyone know if there are codes cast into the heads for identification and if there is a corresponding chart?

Thanks,

bildon.com or BSIracing.com can get you a ported, rebuilt, solid lifter head for about $400 w/ core I think.

Would this be for EP road racing?

Thanks for the info PJ. Yes, it will be for a full prep EP car. I'm trying to determine what model, code or year solid lifter head is the best to start with. Digging thru older posts, I see guys referring to shrouded injectors (a bad thing I'm assuming) and big valves. Trying to climb that big learning curve. http://Forums.ImprovedTouring.com/it/smile.gif

Alex, I believe you can use either of the solid lifter heads. You just put a block-off plate over the air supply for the air shrouding (back of head, between #3 and #4). Unfortunately, I don't have any extra ones lying around.

83-84 Rabbit GTIs (JH engine code) came with the biggest valves I believe, 40mm intake, 33mm exhaust if I'm not mistaken.

There is an EP Rabbit that runs in the Northeast region, the guys at briansgarage.com know him, Mark Megliola, you might even find some pics of his car and engine on the website.

Thanks Bill & PJ. I love this forum, so much great info. Hopefully one day I'll know enough to be of help to someone or be able to contribute to some discussion.

I didn't want to cross post this on the prod forum and thought this seemed to be the best place (most traffic, although I see alot of guys in both forums) to answer this question.

I wonder if Mark C. or Eric P. have read this topic? I'd be interested to hear what they have to say. Not alot of info re heads on the web, at least not that I could find (and I'm pretty good at routing info out). http://Forums.ImprovedTouring.com/it/biggrin.gif

Thanks again guys,

Alex
