STD questions

[Ace$nyper]

how can you get rid of the clap? haha no really i was thinking if i was to get HF tranny and MPFI could I upgrade my car with that cause HF was MPFI just use a SI ecu me idea work? I mean SI parts are sofaking hard to find now adays using HF would be cool with me. I can live with no accel but 5th gear be nice. would this idea work? thx all in advance.

bastages! *bump* come on really for all the help and humor i give you

I would think the HF tranny would suck, the gear ratio is probably totally steered towards fuel economy

wasnt there a dx 5 speed? If so, it might be more driveable than the HF

[Ace$nyper]

yea but i'm thinkin i could grab one cheap if i remember that the HF is same as mine just has 5th gear in it. I see cheap HF stuff on ebay somtimes thats what got me wonrding

etc

all from the search with the terms "gear ratio"

yea doesn't say anything bout the STD and thats same as HF. just HF has 5th gear in it.

yeah, but the hf looks like its pretty wimpy compared even to the dx, personally i just wouldnt bother with the effort without at least going to the dx transmission.

but if you arent worried about performance and just want better mileage i guess itd work fine. but if you really dont care about perf why bother with the mpfi swap?

[Ace$nyper]

i don't mind giving up lil accel for longer gears.

noooooooooo.The hf tranny will be the biggest mistake youll ever make.Get atleast a dx tranny its the same as the si tranny except for the final drive.Believe me i have an Hf tranny on my 1.6 ZC and my acceleration sucks even with I/H/E/CLUTCH STAGE 2/SS/

The hf tranny will be good if you plan to go turbo in the future.

thats a myth. turbos like short gears just like NA.

Get the Si trans.

Dx trans are cheap as hell.. I have one in my garage for sale ($50 plus shipping) with a bad mainshaft bearing. Works fine just makes noise. Could be rebuilt easily.

But I upgraded to an Si... definately a noticable difference. I would go with an Si, if you can find a good one... mine grinds from 2nd to 3rd...

ok so forget hf tranny i got ya. What bout using HF mpfi with SI or ZC ecu that work?
