Real Fiero Tech

why not something like this?



You could mount a distribution block inbetween the #2 and #3 runners, if there's enough room. Tough to tell from the pic.

Well, here's some basic info from the Mantapart website: Upgrade or restore your engine to the factory HO spec valve springs. Can be used with up to .410" lift cams. Spring rate of 75-80 lbs installed @ 1.437" and 205 lbs @1.043". NHRA Legal Racing Valve Springs: Conical factory-type ...

Gotta wait 'till it warms up a bit here. Don't have any Q4 springs laying around since I haven't replaced any (yet). Waiting on a few possible cam options. May be able to find the specs for ya somewhere, though.

Always love the glowing rotors.

Fidanza makes an aluminum flywheel for the 2.8, part number 198261 and it weighs 8 lbs.

Do you mean poor wastegate placement, or are there other factors?

Boost creep usually means that your wastegate is too small. It's not bypassing enough exhaust so the boost 'creeps' higher as the rpm's rise. It's pretty common on the DSM's, also.

Well, the reason for an aftermarket ECU would be because the stock computer can't handle anymore than the normal W41 cams.

How much you want for the turbo?

That's nice, but like I said, I can't afford aftermarket engine management. :fart:

What I'm trying to do with this is make my car go faster without spending much money.. I'm definatly going to add horsepower, but anything above 220hp it starts getting expensive quick, since the quad requires some pretty extensive mods beyond that point. I wish I could afford a Tec 3 so I could run...

I figure the cheapest way to make my car faster is to take all the useless shit out of it. Gonna dump the AC since it doesn't work anyways, ditch the speakers since I have no deck, carpet, sound deadening, etc. I'd like to get the weight as low as possible while still keeping it streetable. 100lbs w...

I'm up here in MN. Freakin cold and I'm sick as hell right now, gotta love it.

I just want to build a stout little n/a quad.

To move it in 2mm you'd want a 44mm offset. I've got 17x7 with 48mm offset on the front of my 88. Looks great, IMO. Although you'll want to clearance the control arms a little to avoid the back lip of the rim from rubbing on them at full lock. On the back I've got 18x7.5 with 42mm offset. I'd go wit...

it's the 180hp HO version. Forgot to mention a set of +/- 2* cam gears. Seems the Q4 reacts well to a 2* retard on the exhaust cam and a 2* advance on intake. I've heard that GM has a few W41 cam sets left, and I think Crane makes some. Although anything over .410 lift will give the stock ECM fits. ...

alright.. now you got me thinking. W41 hot cam - .410 lift, 241* @ .050 Replace all the worn stuff.. freshen it up. Shave the head .020, or if I'm feeling really ambitious pull the bottom end apart and get it balanced, and get some 11:1 pistons. Get rid of the stock IDI and get some MSD coil packs. ...

Welcome to the forum. Ive been a fan of your Q4 88 also. Thanks! I also think Shaun forgot that your Q4 isnt running currently so most stock fiero should be quicker then it in its current form. Only 'cause it's parked in the garage, since it's winter up here in the frozen north :bootyshake: It's be...

Well, when I had the head off the first time I did some pretty amature-ish porting on the exhaust side: http://memimage.cardomain.net/member_images/5/web/209000-209999/209801_68.jpg Other than that.. slightly shaved head, exhaust and intake it's stock. Desperatly needs a timing chain.. I wanted to d...

Well, decided to post over here since there seem to be a lot of the smart people and none of the n00b's over here. I've got a line on a '95 3.4 TDC for $200.. don't know much about it except it's missing the injectors. I've been wanting something with more balls than my Q4 HO for a while now, and I ...
