5SGTE Looking to build it right the first time, Need info, planning Options

[mgnt232]

Posted up on mr2oc because I see a lot more people there pushing into the higher hp ranges im looking for. Looking to hit around 600-700whp dyno queeen (incase anyone is a member on both sites just looking for as much info as I can get). They are giving me a ton of info over there too. I've read through Manny's build for jim a few times as well as others

Looking for input on suggestions to get up to this power goal, my budget I would like to keep around 10k (not including the new GT or 3rd gen clip). It is flexible but pouring more than that into my $3k shell is painful to think about lol.
I realize this post is long to get to the point, what would your swap consist of to achieve my power goal?

So I’ll be deployed for 7-8 months making a whole lot of money and when I get back my plan is to find a clean GT and build up a 5SGTE. The car will be a ‘sleeper ‘ for a while as all the money I’m looking to spend will be in the performance department. Eventually the 3s I have now will go into Tina’s car and stay the SSIII look since its clean, and the new GT will get the supra exterior done with more time than a week like I had with my orange celi now.

Most likely buy another 3rd gen 3SGTE clip. Mainly for the extra parts, uncut harness, and E153. May keep the extra 3S for replacement parts as they go bad on my other one, or sell it not 100% on anything yet.

ATS 2.3L
ATS Head
ATS Racing has a lot of the parts I would need. Looking at the 2.3L 5S (98+ stroker) block seems to be the strongest 5S block I can find. They have 3S heads as well that are ‘700whp’ tested and mr2 owners seem to swear by ATS so as long as I don’t hear anything bad about them I may as well get one that all the work has already been done on and proven to handle 700.
They have cams, gears, turbo setup, injectors ect. But looking into all my options there. Again any input here from experience or knowledge will be greatly appreciated.
Ive read mixed reviews on if the 255 Walbro is enough for this hp goal. Also injectors, what should I be running to hit my power goal (600-700).
Almost forgot. I know I have E53 here in NC but not sure if I have it back in NY. I would like to run it on pump gas (93 or 100) I realize the e53 makes a huge difference in power, but not sure exactly.


As far as the turbo setup, looking at the 6262. It can put out the hp goal im looking for without being the largest turbo ever made. Keep in mind I still want to drive the car, its not a purely track car, but not my DD either.

I know some people here like Art swear by the Megasquirt. I know very little about EMS so any info here would be great. I have a performance shop here in NC that has no problem with tuning, and awesome reviews (they’ve done a few mr2 3S’s, so somewhat familiar) .

There is a ton of info out there I know that, Im reading as much as I can, but not much time to do it out here in the desert lol
Thanks for any info I know this post is extremely long but im pretty committed to doing this, and in my planning stage. I would like to for once do it right the first time I know there will be hiccups (a lot) along the way but planning ive learned it the most crucial part I tend to skip over
Also my PM box only has like 3% free so reply here.

Its supposed to be ridiculous lol that's the idea. I'm buying from ATS because its already tested and works, doing some guess work and trial and error is a pain, that was all my current 3SGTE swap was. Took way more time than it should have and cost way more. Running great now but, again why not do it right the first time, not half assed and go back again to redo it lol

From what im reading on mr2oc, you need a fuel pump that will run with e85 (walbro 485), injectors (ID2000), ECU capable of understanding e85 (flex fuel), and a fuel filter. No mention of new lines there, Ill ask more questions and get a more definite answer. You can run 93 or e85 from what im being told as long as your ECU "understands" and has the correct sensors to monitor the e85 and 93 content/octane level.
ECM Master and Haltech make an EMS that are made to work with e85

I understand the BB will spool faster, but is it a noticeable amount just street driving, or is it more so on the dyno/track where the slight difference is noticed? Ive been reading up to 15% faster spool, and some saying not much difference.

268 run out of steam right about my power goal, that's why I was asking for that. I could have a better low end with the shorter duration, or a better high end with the longer duration. Since its a street car, the best bet would most likely be best with the 268 and have a better low end.
With the 2.3L there is a lot of displacement and spool should be "fast" already, im still on the fence I guess for the 268 or 274. Leaning on the 268
