WRX via t1 transmission

[kleinporsche]

Hi, I'm a big germanlook.com fan. I fell on the link a couple of month ago while looking for Käfercup pictures now I'm hooked up.

Anyways, Here's the question: I'm in a period of questionning regarding engines: a boosted t1, a mildTIV or a 2.5l subaru engine. I would like to hook the engine to my t1 transmission. Subis looks the best bang for the buck, but I called a guy last night who makes VW engine conversions and he advised me to stick to type1 engines (around 1850cc) and forget WRX's because it's to violent for the T1 trans. (a friend of his went through 4 gear boxes since he got it instaled). But still, Jak Rizzo did it (hooked up a wrx turbo to his genuine 1970 box) and it seems to work well...

IS IT TRUE THAT A EJ25 IS TO VIOLENT FOR A STOCK T1 TRANSMISSION???

thanks for all of your inspiration!

If it's a 2.5 turbo WRX I would say don't do it, your box will break.
The single side plate type 1 booxes are the strongest stock type 1 boxes out there.

It all depends on what you are willing to spend, if your getting a 300hp wrx engine you'll need chassis stiffeners big brakes, roll cage,suspension + a strong (read expensive) gearbox.

Are you talking about a naturally aspirated 2.5 (165 HP), a 2.0 WRX engine (turbo, 227 HP), or a 2.5 STi (turbo, 300 HP) engine ?

Either way, eventually you will break your (stock) gearbox.

However, there are high performance trannys available as long as you shell out the $$$.

Thanks for the reply. I'm would like to start with a 2.5l normaly aspired. I saw a 2000 one for 350$ that as a blown crank. For the hp it's cheap compared to a 2.0l porsche +it's about 25 years younger! Should I consider a 2.1 wasserboxer? It's heard it's quite cheap and reliable too. But why nobody on this forum is talking about it? Does anybody know if you can put a porsche fan shroud on the wasserboxer? I presently have a 1600cc, and I'm just looking for some stock power. I don't really want to play around an engine exept for exhaust and carbs.

why would you, a wasser is watercooled.......

makes too much low end torque and would tear apart a stock tranny in no time

But still, Jak Rizzo did it (hooked up a wrx turbo to his genuine 1970 box) and it seems to work well...

jaks got a built type 1 box, not a stock one.

subys have EFI. i think you should stick to buying a built vw motor. an engine conversion will involve a tremendous amount of custom fabrication and kinks.

putting a Suby engine in a bug isn't that difficult really, most problems I'm experiencing are from waiting for the parts to arrive.

If you find a suby engine that has the ecu you can buy a modified loom from outback for about 400 dollars, then you'll need an adaptor(Kennedy engineering and a vehicle speed sensor).
put an electric fuel pump in, piping under the car and mod the front to fit a radiator and that's about it.

I could do my conversion in less then 2 weeks if I'd have all the parts here from the start.

The HP an engine makes has very little to do with whether the gearbox will survive. The biggest factor is the nut behind the wheel.

Bruce, are you suggesting that you can run a WRX engine on a stock trans!?
Hell1 I think that i got to beef up the box if I go over 1835cc on a t1 engine!

Here's what I want to do with it: I certainly don't want to drag race it. I strongly believe that drag is mainly for Cal lookers; their cars are design in that spirit: high big tires and jaked up suspension out back, and skinny tires up front and nose down. While GL is more track oriented. Do you often see Porsche drag events or video. Or modified Porsches for drag? (ok I've seen one on The Samba with a chevy V8 and it's a shame!)

Anyways , I think I've got to rebuit the transmission: Synchro problems I think. The 4th gear pops out in nutral when I go up a steep hill and I hit the gaz... Any suggestion for gear ratio for a daily driver with occasional track? I think the 1st is too short. Thank you all for your replies.

I don't want to go rotary or GM because it's not in the boxer spirit at all. I don't want a f$#@?ing kit car!

guess what i am doing right now? haha yep, bone stock tranny mated to a ej20t.

it works, im sure it would work even if i had a big block mated to it, thats not the point, the point is, Who does all this work to put an engine in a car to haul ***, and never actually get on it. you drive the car hard at all, and id put money on it my tranny would give up, but im not driving it hard yet, im still tuning it to run right.

once the engine is tuned halfway decent, i have a 901 ready to put in it.
Then the fun begins
