$J-MoNeY-$ Posted August 11, 2004 Share Posted August 11, 2004 Well, it's been forever since I've posted, but I have some questions. - What is a good bolt up turbo for the money for a 88 Turbo Wagon? - Can I use a XT pressure plate and disk/throwout/pilot? - What's the Accel part # for the Super Stock Coil? - What kind of intakes are you running? - What's the general consensis on intercoolers? What works best? - Would a 3in turbo back be to big? - How about cross drilled/slotted rotors in front? - How much boost can we run before fuel cut?

Turbone Posted August 11, 2004 Share Posted August 11, 2004 Heres a link on Turbo's... Turbo types The XT6 flywheel is what you want, I believe. Dont bother with Accel, to many going bad. MSD is a good choice. Spider intake from a XT (Some have them, some dont. One from a turbo is prefered. A IC from a WRX works great with the spider intake. 3in might be a little big, 2 3/4 might work better. You want drilled discs? Go for it$$$ Not sure on the fuel cut to boost ratio. You can have fuel cutout with normal boost, sometimes. Hope this helps. Link to comment Share on other sites More sharing options...
subyrally Posted August 11, 2004 Share Posted August 11, 2004 i am currently trying to get a tdo4 turbo from a wrx on my rx, i am using the wrx intercooler and downpipe , i have a 3" cat back for it aka the "ghettoback". i am getting a custom header made for the set up. i just need to get a new ignition coil, new fuel pump, and maybe some injectors.

WJM Posted August 11, 2004 Share Posted August 11, 2004 - What is a good bolt up turbo for the money for a 88 Turbo Wagon? TD04, VF10, VF11....etc... - Can I use a XT pressure plate and disk/throwout/pilot? Its the same thing. Use an XT6, as it can hold more power. - What's the Accel part # for the Super Stock Coil? I would not recommend these any more...as many of the newer ones are starting to crap out, and mine seems to be inconsistant nowadays... - What kind of intakes are you running? Ive got the basic 3 inch ID "typical rice-boy" cone on a MAF adapter plate bolted to the air flow meter/MAF. - What's the general consensis on intercoolers? What works best? For the best in directness and staying with SUBARU stuff...a WRX/STi/Legacy TMIC works best...the WRX ones can be had on ebay for CHEAP. - Would a 3in turbo back be to big? Too small. Anything from 2.5 to 3.5 should be fine. - How about cross drilled/slotted rotors in front? Do not go drilled. I can get CarboTech slotted rotors. - How much boost can we run before fuel cut? depends on year...anything from 85+ will be 9psi. The 85-86 flapper style (pre-MAF) has an overboost switch which can be unplugged, therefor allowing infinate boost. the MAF cars are stuck at 9 PSI until you find some electronic way around it. Ofcourse, with a TD04 or larger and IC and full exhaust mods...you should not need more than 8.5 psi. I can get you a TWE header and downpipe too...the header will bolt any IHI turbo, and the TD0x series (13G, 16G and 20G). The DP only fits the VF7, but there are plenty of aftermarket ones avalible for the new style 5 bolt turbos.

archemitis Posted August 11, 2004 Share Posted August 11, 2004 3.5 wouldnt work, cept with a diesel sized turbo, and dumpin the clutch at 3500 Link to comment Share on other sites More sharing options...
WJM Posted August 11, 2004 Share Posted August 11, 2004 Back pressure after the turbo must be as low as possible. Its up to the cams, header and everything else infront of the turbo to make you move when you want to move. Making the TBE smaller only increases spool, backpressure, and decreses high end performance. Turbo exhaust characteristics are not the same as NA.

subyrally Posted August 11, 2004 Share Posted August 11, 2004 i know you need atleast some backpressure or you wont get a consistant power flow, or something like that. Link to comment Share on other sites More sharing options...
suberdave Posted August 11, 2004 Share Posted August 11, 2004 i have an 88 turbo wagon, and i have my turbo manualy regualted at 11PSI and i have never hit fuel cut, untill i opened the intake up to a 2.5 inch pipe into the throtle body, went back to a 1.5 inch, no more fuel cut. -=suberdave=- Link to comment Share on other sites More sharing options...

Mostly they stayed around 14. The other RX, Pleiades current one, will hit it ocassionally...but its not a regular cutter. i know you need atleast some backpressure or you wont get a consistant power flow, or something like that. The turbo's exhaust turbine provides all the backpressure that the system needs. Link to comment Share on other sites More sharing options...
$J-MoNeY-$ Posted August 12, 2004 Author Share Posted August 12, 2004 So, back to this fuel cut thing. Has anyone installed a FCD or custom fabbed one? I know a guy on bbs.legacycentral that made his own. Quite ingenious. Link to comment Share on other sites More sharing options...
WJM Posted August 12, 2004 Share Posted August 12, 2004 A few have...skipper, subaru tex, and...oddcomp? I have not, since i never had a fuel cut issue....and i have an 86 i primarily work on. Link to comment Share on other sites More sharing options...
$J-MoNeY-$ Posted August 12, 2004 Author Share Posted August 12, 2004 How can I make one or buy one? Link to comment Share on other sites More sharing options...
WJM Posted August 12, 2004 Share Posted August 12, 2004 UUuuuuhhhmmmmmmmmm.......buy an 86 turbo car and not worry about it? Seriously, I have no clue on how to build the FCD. Link to comment Share on other sites More sharing options...
