Crazy K Posted October 26, 2007 Report Share Posted October 26, 2007 Me and Psychomatt located a 92 or 93 HO Q4 with 5 speed beretta in a local yard today. I can buy the guts out of this car outright for about $300, and if I do that, I would put it to work in a W. so here are my questions. Is this a Getrag or an isuzu tranny? if it is a getrag, I might use half of a 282 w body case to make it w body compatible, if i cannot fab up my own mount for it. engine mount: if this is W specific, I can grab one from a Q4 automatic, I assume? computer? what did a real W HOQ45spd use? chip? I have a card reader I need to set up to use. anyone seen available BIN files for this car? axles? regular 282 axles? clutch operation. don't know yet. Help this madman out guys! I already pulled a 284 out of a 91 STE today in about 3 hours. RIP! Quote Link to comment Share on other sites More sharing options...
GutlessSupreme Posted October 27, 2007 Report Share Posted October 27, 2007 No W's came with an Isuzu tranny. they're all Getrags. Quote Link to comment Share on other sites More sharing options...
ManicMechanic Posted October 27, 2007 Report Share Posted October 27, 2007 But L and N bodies came with Isuzu 5 speeds. However, the Q4 5 speed was a Getrag. Quote Link to comment Share on other sites More sharing options...

Andrew Posted October 27, 2007 Report Share Posted October 27, 2007 doo eet!! that is the getrag, the isuzu trans came in later years. AND the 92 Q4's were the best for reliability and power!! if you already have a q4 W the motor mounts :should: be the same. the trans mounts will be different though, as you know. and i am thinking at least one of the axles are different since the N body is narrower. for info on the bin file and such, if no one here can help you, check the 'quadfourm' on yahoo groups. Paul hacker, who used to race a SCX in the 'IMSCA firehawk series' frequents that site, and he has lots of Q4 knowledge. Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted October 27, 2007 Report Share Posted October 27, 2007 Ok........... 1st off: Isuzu trannies in J/L/N body cars ONLY came on the 2.0/2.2 base engines UNTIL 95..................THEN the Quads all switched to the Isuzu, with the engine morphing into the 2.4L TC a year later. Soooooo.........if it's an 89-94 Quad HO, it IS an HM-282. 2nd: Gearing changed a LOT on the Quad version of the 282.............89 is different than 90, is different than 91, is different than 92-94. But since the one YOU have found is a 92 or 93, it actually has the BEST gearing for a W-Body with the LQ1 (or for a Quad........well.....except for the rare W41 trans option......THAT has the best Quad gearing due to it's shorter 5th gear)........ 3rd: Not 100% on this, but while you most assuredly CAN use the tranny's guts, the bllhousing is different between a Quad and any of the V6's, AND I gather the other case half has different mounting points for where the trans mounts actually bolt TO the tranny. This means, you will probably need to source a W car tranny CASE. But if you do THAT, then off you go.......... Quote Link to comment Share on other sites More sharing options...
Crazy K Posted October 27, 2007 Author Report Share Posted October 27, 2007 YOU FORGET... I am interested in making a HO Q4 W body! the only reason to swap case halves... is to use the OEM tranny mount location. If I can..... I would make my own mount Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted October 27, 2007 Report Share Posted October 27, 2007 Ah hah.......... Interesting concept Do what you can to make SURE you have either a 92-94 Quad trans, OR a 91-93 W41 trans. Do NOT get an earlier Quad transaxle, as they have longer gearing that will suck ass with the taller tires and heavier weight of the W-Car. As for the engine, a W41 style .bin is what you will want (with a 7400rpm rev limit), as even the HO's want to rev higher than their stock 6800rpm redline (peak power is in the 6200-6400rpm range with HO cams, and 6800ish if you have W41 cams). Match the W41 tuning WITH W41 cams, and you will have plenty of top end..........but I'm wondering how bad it hurts down low, and if THAT is a good idea..........W's are fat and hevay after all Also look at a "Vin A" crank pulley from an 89-90 Quad HO and an 89-91 exhaust manifold (it flows better).

I need to look at the car more. I also need to determine how to be certain about what makes it an HO Q4. Quote Link to comment Share on other sites More sharing options...
BIGBULS Posted October 27, 2007 Report Share Posted October 27, 2007 Good point about verifying it's an HO. ALL Beretta GTZ's were HO's from the factory.............but some have popped motors that were replaced with LO long blocks.................THAT would suck a bit, but it WOULD make a nice start on a Quad 4 TURBO engine Quote Link to comment Share on other sites More sharing options...

Crazy K Posted October 29, 2007 Author Report Share Posted October 29, 2007 CORRECTION: It is a 91.... but it has 238,000 miles. Also availible in the same yard is a 91 GP quad 4 automatic. Here's my plan. test the beretta as best as possible. wheels in the air, try to start it and operate it in all the gears. remove the motor, transmission, shift cables and hyrdraulics as a unit. remove the quad 4 GP's wiring harness and ECM, then remove the engine and tranny as a unit and steal all the W specific mounts. quickly install the donor parts from the W quad on the beretta drivetrain and GTFO!
