alright guys, sorry if this sounds dumb but i wanna know lol. ok im getting a 96 Eagle Talon ESi for $100, just needs new struts and battery, and the rear quarter glass. now it has the 420a DOHC motor in it. it is also a dang auto its going to be a DD and im not gunna swith the tranny out. so, my question is how much boost would i be able to run on the STOCK 420a, with a stock auto tranny? now this is only going to be for a lil more pick up and go. im not going to try and make 500hp lol. so any answers or help? anyone done this? ive read on other forums, that the stock 420a completely stock can handle alot of boost upto i think like 15-22 area. i dont remember wxectly, so sorry if im wrong. and that the auto tranny should handle like 10 or so. so would like 7-9 psi on a stock auto work? please no smartass just trying to get some answers thanks and sorry for all the reading

welcome. first thing look at how many miles are on the trans. if it more than 150k be careful because you dont know the history of the car and if the trans has ever been serviced. change the fluid if black and filter a long with a bottle of lube guard or lucas and a trans cooler( the bigger the better). needs struts get the tokico and eibach kit they sell on ebay. my wifey had a 95 eclipse auto and it was pretty quick for all motor and we had the basics i/h/e coil wires plugs pp intake 50mm tb and it did 17.2 with out the intake and tb. we where looking into boosting it and she was on team-2g.com? cant remember but this guy threw on an ebay kit and on 8 psi it hit 14.8 with problems going into overdrive ant the end of the track.

the 420a can NOT handle high boost. the rods are a compressed powder and are only good for about 10 psi on the street. yes there is one person running 15psi on stock bottom end doing 12.s butt thats alot of fuel. most people have to rum an fmu because the fuel system is not returnless so no fpr upgrades its internal at the fp. if you have to keep the auto see if you can find a pt cruiser turbo trans. its a direct bolt up and its good for 300hp+. theres your car in a nut shell good luck. and look into bolt ons before boost. happy boosting.

ya i plan on doing a full fluid flush, and tune up and all that. ya im not trying for a big hp car, just a lil more zip. but you say a PT Cruiser tranny will hook up? will it fit with any modifications?

5G_4G15

only mod i think is you have to use your trans mount or mod the pt cruiser. its been so long man but im pretty sure thats it. post pics of the car if you get it.

i should be picking it up Wednesday hopefully. i have a near complete turbo kit. i was going to turbo my civic but i figured id enjoy it more on this Talon.. and i see ppl turbo auto n/t eclipses and talons.. just not really of auto's... but just as is, you think like 5-6 psi would work? as a dd? like nothing heavy or anything. i mean that should give it a lil more go

5G_4G15

i boosted my mirage 1.5 auto on 5 psi and no problems besides trying to tune it. it depends on the fuel system on that car for how muck boost you want. 5 maybe on the stock fuel sys and fmu but anything more you need an safc or emanage. anyone on here will tell you you will not be happy at 5 psi.

ya i know i wont. atleast not for long. but i figure itll help me learn more though to. i plan on alot more to the car eventually. but i wanna turbo it now lol. well maybe in the spring.. lol just needa manifold, and i/c and BOV and some ic piping... i figure itll be a good start. and if i do blow the tranny, well that just gives me more reason to but a 5spd and swap it.

i would rather put a turbo on a civic and not have to worry about it falling apart the 420a is a piece of ----. search on here a guy did it and it did not turn out well and he had a ---- load of problems just like every other eclipse owner does. those car are notoriuos for being unreliable in factory form let alone turboed

david_mutchler

im on a few forums, and ive seen alot of DSM owners do it very succesfully..

then why dont you ask them how to do it. all i know is the 420a is unreliable stock so i wouldnt turbo one. i had an eclipse with one and it sucked.
