SVT TB to SPI TB

2829 36
Can I swap these out, or would I have to buy an SVT header for it to totally fit correctly?

I want to go to 65mm TB

The header has nothing to do with the TB. You would have to get a SVT intake manifold for the SVT TB, and them I dont even think the SVT intake will fit onto a SPI head.

Oh I must have read something wrong then. So to get a 65mm TB I would need to buy one used specifically for my car or buy new then? More research is necessary tomorrow.

As far as I know, but I could be completely wrong.

Moved to SPI performance.

Free - look at the info. here:http://www.focusfanatics.com/forum/showthread.php?t=322445

Includes a link to an alternative throttle body for the SPI.

That & the other stickie in here might help you out with options.

Thanks for the link. When I saw your post I just assumed it just moved to SPI performance.

How does the SVT intake manifold pair up with the SPI? Would it need modification to use the svt 65mm TB?

Doesn't exist that I've found bud. Sucks indeed.
For the cost of making the SPI decently quick, you might as well turbo it or do a ZETEC swap. Not trying to say anything negative but that's the route I've decided to go.

Gave you a little more than just a move...

Driving a slow car fast is the best attitude for the SPI, you can push it harder than a faster car without getting in trouble.

A bit of modification can add to the fun if you want, even 36 hp. VW's were Hot Rodded to get 45 hp for more fun (yes, more extreme was avail. then as well - not practical for most.

Check those stickies & search for ancient threads, post up want to buy threads in BST for old performance parts folks may still have around. You can def. have fun with what you already own.

There are still a few here with SPI experience, so eventually you may catch more hints from them.

Cheers

Yeah you did!

I looked at a couple of them. And yeah I visit some ancient threads today from 2004 about some headlights...

It's not that I want to push it. Just run more efficiently. As I got 35 mpg today.

Seems the SPI knowledge gap is gettin bigger and bigger.

Thanks again.

Honestly I'm glad the SPI has it's followers. Having built about 4 different oddball chassis cars and fabbing everything myself I respect that.
To give some insight I have the following on My SPI
Mustang TB
Custom coil on plug setup using Audi coils
Cat delete with 2.5" exhaust
Intake setup
My own short shifter
It's fun to drive I just won't sink anymore into the spi.

What do you think about the whole valve seat issue?

How hard was the mustang TB to do?

The valve seat issue is a real issue for sure. When it goes is when my swap happens haha.
The mustang TB wasn't too involving, a few hours at best. It does make a nice difference in throttle response.

Also I'd like to add how I protect myself proactively from the valve seat doom.
I'm running 5W40 chevron Delo which is very high in ZDDP.
Also I run mystery marvel oil in my gas as a top end lubricant.

Yeah it'll happen. But I firmly beleive being proactive will extend the time it takes. High zinc oils are proven to work miracles on finicky engines and materials ;)
