I am looking for your opinions, buy a renn shift or keep the stock shifter. Will the rennshift help the ol stick in the mud affect? Also, I do have the factory center console. Any mods needed?

If you can afford it, I have no doubt the Rennshifter is money well spent. However, the rest of your shift linkage/bushings need to be in shape because it can't fix problems farther down the line.

The Rennshift was the best investment I've made in addressing Porsche's weakest link on both my current 914-2.7 conv and the 911 I had before that.

Period.

Rather expensive but if you love driving your car and can shell out the $$ I personally love mine it’s night and day different although as said above replace the bushings. I also have the consul no problems but I must admit I had it installed along with all new bushings

Depends on what you are trying to accomplish. Yes it's nice. You will still have to replace the bushings. Try replacing the bushings, if you still have an inclination to drop more $$ on it, then do. The stock does well when adjusted with new bushings. It may be good enough?

It is a good product, I had it in one of my 911s, but as said above the rest of the shifting "circuit" needs to be healthy.

As an autocrosser, I swear by it. Had it in both of my last 2 race cars. Street. Its really your call. I'm not in that big of a hurry on the street, and the shitty inferiority of the stock shifter has its own character.

I put a rennshifter in my 911sc, the old shifter needed some new springs.

I got a rennshifter with a taller stick and then put a wevo knob on the top with a threaded insert to make it work. Super tall and I love the hell out of it. I also put all the spring spacers in, maybe it needs it maybe it doesn't.

Better pic. The shifting is way, way better. But what I really like is the shifter is closer to the steering wheel.

I like mine, can't add to what's already been said...other than it looks more like a 915 shifter giving it a bit of a cool factor.

Travis I like the longer shift handle.

This is a great racing secret.

I used a longer shaft when I was racing and the hand to stick action was outstanding.

The time gap in shifts disappear which = faster. On the street its just fun and quick.

The shift knob is nice as it sits on top of the long shift lever, vs the rennshifter or stock knob that slips over, so I get an extra inch or so of height..

I got the idea from someone who did this on pelicanparts.

Does the rennshifter work with side shift linkage?

Yes.

There used to be rennshift linkage too, but sadly it is no more.

Tangerine racing has an excellent replacement for the linkage.

I tried everything with the 914 trans
-weltmeister short shift kit
-weltmeister springs
And then the rennshift. Nothing better, but is it worth the money?
That’s up to you. It was worth it for me.
They also sent me the parts to convert it from a 914 side shift to a 911 trans.
The conversion parts were quite reasonable versus buying a whole new rennshift.

Rennshifter works with the stock linkage, His shifter will work with side shifter or tail shifter.

The other linkages people are talking about is in the engine bay to the transmission.

For a tailshift car, I bet a good inexpensive upgrade would be to get a 915 shifter, put wevo springs in it and be good. If you wanted to go farther you could extend the shifter with a slug and longer tube.

Been there.. done that. Wevo and 915 shifter is more expensive than a rennshift.
Nothing shifts better than a side shift 914 trans with a Rennshift.

WEVO is nothing but new springs and a new stick, yes? If so, what I said might be good

Yes, you are correct, but the issue with a tail shift, is the tail shift. That’s why Porsche moved away from it and switched to a side shift. I have owned and tried all these combinations. Wevo and 915 shifter would be a huge waste of money with a 914 tail shifter. Most people convert to a side shifter and if they have the extra money buy a rennshift.

I would like to confirm that this does work with he factory center console and the leather shift boot.....true? After 40plus years of driving a 914 it would be nice to have a change away from the stock shifter

It won’t just drop in. You have to modify the opening in the console and probably the leather boot.

Recommend rennshift- have it on my '71 (with converted side shift) and my '73. Looks even better with Zach's knob too...Click to view attachment


Really improves the 1-2 shift...

Thank you all for the input. I just bought one today. Once I get it and work on getting it installed, I will most likely see what you all have been talking about. Once winter is over of course! Thank you all again.

Other than a Honda.....lol

Hi guys,
I am putting the finishing touches on a 1974 914 3L conversion with a side shift. I have driven the car and the power is great, but... the shifting sucks. Particularly neutral to 1st.
I have been thinking about a wevo or a rennshifter. Reading this thread I am tilting towards the rennshifter.
SKL1 mentioned in the above post that it really improved the 1-2 shift. My question is; how is it from neutral into 1st ?
Thanks,
Bill.

Are you sure it’s not the trans or the clutch adjustment.

Both of my teeners are bitchy from neutral to first....especially sitting still. Make sure the clutch adjustment is correct, lots of guidance on that here on the board. Beyond that I have developed a consistent habit of double clutching & dropping into first just before rolling to a stop & it snicks in just fine. BTW one has rennshifter, one doesn't....there is a little difference but optimizing the bushings first makes a huge difference.

Im a little confused
Is it the stock shifting your having trouble with
Or the 1st gear " raceing start "shift pattern .



My teener is actually pretty smooth n.to 1 and 1st to 2nd

But i think the stock setup 2 to 5th is really solid


And i would not ever recommend downshifting 3rd to 2nd in a 914

1st used once during the whole race

Took the plunge and ordered a RennShift for my stock 901 side tranny. Will report back when installed later next week

I'm not sure I want to sacrifice my hand throttle mechanism.....

I've seen people jury rig them. I'd have to be convinced this is a huge step forward.

Never use my hand throttle. will see if I can "modify/keep" it.

914forme modded his rennshift for the hand throttle

I’ve got the whole Rennshift package from the shifter to the transmission + the McMark modification. Overkill for the street, but nice if you do track days or autocross.
Street, I’d just do a well serviced package...

why longer?
are you hitting the dashboard or seat in certain positions now?

Here is a link to the thread showing 914forme's Rennshift modification for a hand throttle. See post #213. Here is the photo:

http://www.914world.com/bbs2/index.php?sho...9606&st=200

That is similar to what I was thinking. Have to look closely at how the space for the throttle handle baseplate is accommodated under the shifter base plate.
Also, possibility of mounting the hand throttle assembly say 2' in front of the shifter base plate on the tunnel by drilling holes for bolts and cutting slot for handle and shortening the rod the same amount (?)

See tons of positive comments but can’t tell if it’s being used on a 4 or a 6. Who is using a Rennshift on a 6 converted with a side shift 901? Does it work for you? Love my teener but shifting has always been its weakest link. Fixing that make the car even better.

Mine has been both a 4 and a 6 with the Rennshift And shift rod And McMark mod.

Same transmission, it doesn’t matter if it’s a 4 or 6 or 8 or Mazda rotary or Subaru
The only issue with a six is the shift rod has to be straight or it will hit the motor.
I have used my rennshift on a 4 and a six with the same side shift 914 trans. I then converted to a 915 trans. JWest will sell you the parts to convert the 914 side shift rennshift to a 915 rennshift. Pretty simple conversion.

Can’t find any mention on the JWest site of 915 conversion parts or a kit. I do see the 914 side shift shifter. Do not see a straight shift rod being offered. Hmmm . Still not clear on what the McMark mod is.

JWest sells two Rennshift models
914-4 side shift
914-4 tail shift and 915 gear box.
I originally had my 914-4 shift rod straightened when I did my six. Later I converted to a PMS shift rod for my six.
I don’t think JWest sells six conversion shift rods anymore, but PMS and CFR (Tangerine Racing) does.

Thanks Steve for all the help. Parts ordered. Much appreciated and Happy New Year

I think I know what the Rennshift (Jwest) package is, and also the Tangerine linkage kit, but I am not familiar with the McMark modification. Could someone describe this and maybe post a picture? Thanks.

I installed a Rennshift earlier this year. It was an improvement, but wasn’t as dramatic as I hoped. But I’ve felt others and they were superb. Perhaps I need some more adjustment?

Regarding the slot for a hand throttle? It wasn’t hard at all to cut one into the baseplate and install the hand throttle per usual. Mine works great. I also used the Wevo knob, but I elected for the one that slips on with a crush sleeve.

Yeah, worth every penny.

To easy to do and no other modifications needed. Also gave me a good reason to make some chips fly.

If you don't have access to a mill, it can be done with hand tools. Drill a hole out back big enough for the post to run up through, and then just cut two down the center. It is strong enough that flex should not become an issue with the minimal removal for the handle to move.

You also have to drill one hole for the nub oil the hand throttle mount to key into.
