4A-GTE Configuration Questions
I presently have a Silvertop 20V 4A-GE in an AW11 MR2. I have a Haltech E8 with MSD DIS-4 ignition. I have a GTP38 Turbo from a 6.0 Powerstroke. I'm planning on running a liquid to air intercooler setup. Aiming for 400HP. Planning on using a Quartermaster 2 disc 5.5" clutch. I hope to retain the use of the VVT system if possible.
Questions: 1) What size BOV should I use? I'm looking at a 40mm and a 50mm 2) Do you think this turbo would work on the 1.6 without surge? 3) Any cam suggestions? I was thinking 280 intake 305 exhaust, (Head is race ported) 4) Any other suggestions or comments? |
Re: 4A-GTE Configuration Questions
Any decent bov will work, I don't know much abou that turbo so i cannot comment. The vvt system should work fine, but those cams are somewhat ridiculous. Depending on lift you're going to most likely need underbuckets. Look on www.mr20c.com their are a couple 400whp 4ages on their. If I were you I would ditch this idea completly and do a 3sgte.

Re: 4A-GTE Configuration Questions
all i know is the 4ag doenst like aggressive cams. it'll puke em right back at you in the form of metal internal parts.
you can go safely in the low 270's. |
Re: 4A-GTE Configuration Questions
and if 3sgte isnt baller enough for you do a beams 3sge+t

Re: 4A-GTE Configuration Questions
Look at this build maybe some ideas for your setup: http://www.geocities.com/MotorCity/L.../20-valve.html its in a ae86 but why not twincharge it yeah.
Uncontrollable wheel spins yeah!!! |
Re: 4A-GTE Configuration Questions
$ for $ you will not get better hp gains and reliability. The 4age needs $$$ to make big boost, my gte makes 230whp and i did it all HMT getto fantastico. But to hit 300 nm 400 you're gonna have to spend way more and your reliability will ---- the bed. Besides ---- hp, get some torque its way more fun

Re: 4A-GTE Configuration Questions
check out this site this may help on modifying the 4ag 20v : http://www.billzilla.org/4agmods.htm
and answer some of JD's questions about what breaks in these engines. |
Re: 4A-GTE Configuration Questions
Advised the guy with the twin charged engine, his configuration all wacked. Its not a true Twincharged setup. True TwinCharged has no bypass valve, it compounds boost. I'm sticking with my 4AG and it already had underbucket shims, they come that way. I believe if my memory serves me correct, this is the closest compressor to the GTP38 garrett shows specs on http://www.turbobygarrett.com/turbob...1_731413_1.htm They say up to 390HP. as far as the $$$, I do my work myself and have the skills and ability to make about anything I need.
And between the VGT and VVT, I should have all the wheelspin I need available. My goal is to set up a road speed to boost level map in the E8 so I wont be skatin all around on the streets when the boost comes on. |
