festiva transmission max power

[1988festivuh]

I’m looking to add power to my b3 but I was wondering how much power the 5 speed transmission can handle before blowing out. I’m looking to put a b6 soho head on it and port the head, add some long tube headers and upgrade intake and injectors. Looking to pull 120hp but will the tranny hold up. I know I need a better clutch for it. I really don’t want to do a transmission swap I like the stock gearing

Depends on how you drive it. Beat on it, it’s probably gonna break. I think they are good for around 100 or so horsepower. I don’t recall the torque rating. A couple of folks on here have raced them and not had them break until they were doing high rpm launches at around 150 hp.

1.6 heads do not work on b3. just port the b3 head.

I have a b6t mated to the stock transmission and have had an extremely difficult time finding a clutch that will hold enough to cause damage.

Right now I have a custom clutch by kentucky clutch with ceramic faces and increased clamping force and that still slips.
Now, you may be able to break it if you try doing a burnout or something...

Charlie is running his current b6t powered car thru a 4 speed E series. Last I knew he was pushing 160hp and planning on bumping that up. His current engine/turbo setup is capable of 250hp or more. Not sure what he is running for a clutch.

And yeah, it sounds like you are gonna make yourself have a bad day trying that head swap. Open up your b3, or do the full b6 swap. Either way your hp prediction is a little off.

I think Charlie is testing a b6t+E on track currently.. iirc: it's wild but still holding.

No burnouts, don't dump the clutch, and try to avoid acceleration over bumps/gaps that allow the wheel to spin-grab.

edit>> bhaz already said.. sitting here doing other stuff after typing that out. toot-doodles-ciao

I have a gen2 SOHC B6 with Matt Dickmeyer-modded head, and his headers. It dynoed at about 97 wheel HP, so maybe 107 - 110 crank HP. The tranny can take it, no problems.

Besides porting and flow-matching the stock injectors, he also added larger valves and more camshaft lift and duration. I don't think that porting and a header alone will do much; also, IMO larger injectors would be pointless without larger valves and more cam.

Previously this motor (with unmodded head) had a rear turbo, and made somewhat more power than what I have now, probably about 120 at the crank. It would slip the stock clutch (which was not a new one). But as long as I just accelerated while already underway, and didn't launch it from a stoplight, no tranny problems.

I found a 89 tracer 1.6 sohc. What do I need to pull from it for a successful engine swap. And which clutch and flywheel should I use? The 1.6 or the 1.3 do I need the ecu?

[Team Lightning]

Clutch/flywheel should be the one used with the trans you are using. I.E, e-series trans, e-series clutch/flywheel.

You can use the B3 ECU/wiring, if I remember correctly on either the B6 or B3,

[shorestiva]

Grab the b6 vaf/ecu if you can.

I think Matt got like 90chp out of a b3. Is that right?

IIRC mine dynoed at about 87WHP.

I think he eventually ended up getting more than that after the turbo but there is only like 1 video of the car running that I can find.
