gottraction Posted July 5, 2012 Report Share Posted July 5, 2012 (edited) Alright guys im trying to debate if i wanna put the money in my 1987 quest to try to achieve atleast a mid-low 12s. Im selling my Mustang so im either picking up another toy or throwing some cash in this. My Current setup is. hardpipes,190 fuel pump, upgraded coil,1st gen mass air,20g with mbc,650,950 trilogy injectors,89 ecu. With an additional 2k to 2500 what could i do to make alittle over 300whp. I do want to keep tbi for ac. And i know its going to be alot harder with the car possibly running lean on 2 cylinders. It would be nice if i could do 300whp without cracking the motor open. What would you do and is it possible? Thanks Edited July 5, 2012 by gottraction Link to comment Share on other sites More sharing options...
The Rabbit1 Posted July 5, 2012 Report Share Posted July 5, 2012 2g MAF, SMB custom manifold, Lower shores ported intake, ported manifold, 20g (or maybe bigger) turbo, and then try to figure out how to tune for all that air flow.. Link to comment Share on other sites More sharing options...
Starwolf Posted July 5, 2012 Report Share Posted July 5, 2012 First off do not buy an SMB manifold.... I can agree with the 2g maf and larger injectors...but remember if you stay with stock ecu you have to run a smaller primary than secondary. 20g with the right hotside can achieve your 300whp goals. If you run a td05 or td05h it will really choke the engine. A 3 inch exhaust and larger intercooler and run about 22+psi and you should be getting close Link to comment Share on other sites More sharing options...
gottraction Posted July 5, 2012 Author Report Share Posted July 5, 2012 i just installed a td06 20g so im good there. what injectors can i run with? I dont think i saw any high bolt in injectors when i originally bought my trilogy ones. i saw i think on 26liter that someone was running 2 factory secondary injectors. you dont think i can just buy a 3inch downpipe and run 2.5 back for 300+?

Starwolf Posted July 5, 2012 Report Share Posted July 5, 2012 Well for 300whp I figure the 2.5inch will work and not hold you back much. But the bigger the better. Well you can't run two secondaries unless you are using a standalone ecu. I run megasquirt on TBI and I am using 2x 1150cc injectors. You would probably want to go with something large for a primary like 800+ and then a pretty large secondary. There should be a ratio somewhere or someone might chime in. You should NOT run two of the same size injectors on the stock ecu though. Link to comment Share on other sites More sharing options...
gottraction Posted July 5, 2012 Author Report Share Posted July 5, 2012 (edited) ok well i will look to go up to atleast a 3inch downpipe. are there any injectors i can buy online that will just bolt in using a 2gen mas with 89 ecu?

19cturbo Posted July 5, 2012 Report Share Posted July 5, 2012 MPI??? dang that was simple Link to comment Share on other sites More sharing options...
Starwolf Posted July 5, 2012 Report Share Posted July 5, 2012 You pick the size of the injectors. So you can go with whatever you want. I would suggest buying from brianpaul on these websites.I hope you aren't a novice and can figure out the 2gen mas. It shouldn't be super difficult but if you are willing to try something you should just go with a full standalone ecu Link to comment Share on other sites More sharing options...

gottraction Posted July 5, 2012 Author Report Share Posted July 5, 2012 im not a newb when it comes to cars. ive had a hand full of dsms and rotarys. just never had a g54b. i was thinking about megasquirt but i see members here that are doing 300whp on 2genmass air Link to comment Share on other sites More sharing options...
Starwolf Posted July 5, 2012 Report Share Posted July 5, 2012 A few are. Here is a helpful table if you can view it. Not everyone is on that list obviously but if they care to be considered top 10 then they are. http://sqperformance.forumcity.com/viewtopic.php?t=158 Link to comment Share on other sites More sharing options...
wrngwae Posted July 5, 2012 Report Share Posted July 5, 2012 why no MPI??? you can keep your A/C and be MPI,,,, just need the right manifold. Link to comment Share on other sites More sharing options...
Lizzord30 Posted July 5, 2012 Report Share Posted July 5, 2012 (edited) I would go with GM mas with the adjustable thingy over 2g mas, then have adjustable and I think a GM one flows better also. With that can use different size injectors and adjust to work. Lance is useing that with WBO2 to tune with 2 secondary injectors and really its mostly smooth and has more fuel(which you will need). And go 3in full exhaust, dont mess around with anything less, not worth the work for smaller. Edited July 5, 2012 by Lizzord30 Link to comment Share on other sites More sharing options...
gottraction Posted July 5, 2012 Author Report Share Posted July 5, 2012 i just havent seen any mpi locally that has kept their ac. I also thought 300 whp was obtainable of off tbi thats why. I will add gm maf/translator to the list. Thanks for the info guys. Link to comment Share on other sites More sharing options...
StarquestRescue Posted July 6, 2012 Report Share Posted July 6, 2012 A safc2 or neo afc is typical used to tune with a 2 g mas. The afc's have 2 load ranges and rpm tuning, 32 tuning point for a neo ($250 used) vs 3 knobs for the translator. A afc can also be used with the maft for fine tuning, but the ecu will like the 2g airflow signal better. Link to comment Share on other sites More sharing options...
Technology Posted July 8, 2012 Report Share Posted July 8, 2012 Just want 12s? get some slicks, a sticky clutch, an open downpipe, a 1G mass air sensor and turn up the boost! 12.9 @ 100 mph all day. Link to comment Share on other sites More sharing options...
