MyLaDyZ Posted October 1, 2009 Share Posted October 1, 2009 Im still debating on a sr or 2j. but everyone that has the 2j swap are running a big single turbo, I just wanted to know is, when switching to this single turbo set up what changes to the ecu are needed for the conversion?

Overkill Z Posted October 6, 2009 Share Posted October 6, 2009 umm im pretty sure you will need to do some changes because the boost comes on a a completely differnt time then stock twins...more boost=more fuel needed and im sure the stock ecu cant handle the extra boost.

Gritz Posted October 6, 2009 Share Posted October 6, 2009 Theres guys running 450+whp with stock ecu..with a piggy back of course...however with stock boost most small singles will be ok with supporting mods.. bigger fuel pump, upgrade fuel pressure reg, Wide band..etc So no, you don't have to do any changes to the ECU.

Overkill Z Posted October 7, 2009 Share Posted October 7, 2009 well that would be a "change" to the ecu then Quote Link to comment Share on other sites More sharing options...

MyLaDyZ Posted October 7, 2009 Author Share Posted October 7, 2009 got y'all i understand the minor upgrades i was thinking like you'll need standalone Quote Link to comment Share on other sites More sharing options...
Gritz Posted October 8, 2009 Share Posted October 8, 2009 got y'all i understand the minor upgrades i was thinking like you'll need standalone Well thats the way i understood the question, which is the reason i said none..I Guess mike took it the other way.... I do know to get full potential from a nice sized single, standalone is the way to go. But stock boost around 400whp is safe on stock ECU...Some go for more and exceed, but tunning becomes less safe with the stock Ecu as the power increases.. Thats when things like map ECU, SAFC...etc are pretty good tools to use...After that is full standalone for the 550-600whp guys... Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted October 8, 2009 Share Posted October 8, 2009 If you are considering swapping a 2JZGTE, you aught to know what BPU is, etc. Get on the supra forums. It is covered a million times. An S-AFC goes quite a ways. A small single can be managed quite easily. I would do more if you want to put a T88 on, etc. Will all the money in a big turbo setup, you should be doing the whole package. The factory ECU is quite well designed and goes quite a ways. Anyways, the entire modification route has been laid out well ahead of you. IMHO, the mkiv supra powertrain costs so much because of the potential (big power top end, lots of stock bottom end capability, heavy trans). If you don't plan to make use of it (with big turbo/s and whatnot) you're really not taking advantage of the money you spent. The SR20DET is quite abundant, cheaper, lighter (to some degree, let's not get into that discussion), etc. But hey, if it's the engine ya want, it's all good. I've tuned SR's for customers and friends, but only owned the 2JZ myself, so I've nothing against it, for sure. Quote Link to comment Share on other sites More sharing options...

Thanks for you input ill keep everything in mind, sr is the way im leaning towards, but the power of the 2j is to tempting. I'm not trying to build a all out race car i just want a Daily Driver that has some good power so i can keep up with the newer gen cars evo, sti, s2, mustangs, m3 etc. Quote Link to comment Share on other sites More sharing options...
sweetleaf Posted October 10, 2009 Share Posted October 10, 2009 As everytime this question gets asked, it really depends on what you looking for. If you have a smaller budget and want to stay simple. The L28et can go a long way. The 2 motors your considering are in a complete different catagory. So first you need to figure out what YOU want and WHY?

MyLaDyZ Posted October 11, 2009 Author Share Posted October 11, 2009 I'm not really interested in the l28, i know all these question have been ask wat is better, this and that , I've read lots of these fourms, I just wanted to see wat requirements were needed for a single t swap . Thank you for all your inputs it did make me rethink some routes I was going to take Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted October 25, 2009 Share Posted October 25, 2009 If you 'gotta' have the 'big supra power', go with a 1JZ from a jdm mkiii supra or soarer. It's 2.5 so it can rev pretty nicely. I guess you'd say it a compromise in cost, power, etc. between the 2JZGTE and the SR20DET. Lots of parts swap with the 2J and it makes good power. Honestly, I was on the fence between the 1J and RB25. The RB is just 'teh sexiness' in sound (like a naughty L28) but the 1J just makes retarded power for what you've done. Once you get past boost cut and fuel limitations, it pulls away from the RB25. The SR is no match in that aspect. Cost is pretty much the same for a 1J.

Overkill Z Posted November 23, 2009 Share Posted November 23, 2009 Just by reading about your wanting a daily drive i would REALLY consider a L28et. IT will BOLT in... you put big injectors, big turbo,maybe cams/intercoolers....you will pull from an SR at half the price AND half the difficulty scale. Parts will be cheaper and easier to get your hands on... your car will be down for HALF the time and you can drive it to work. Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted November 24, 2009 Share Posted November 24, 2009 There will be a 'change' to the ECU for about any car with mods like you guys are discussing. Likewise, an L28Et will require some substantial stuff to deal with injectors, turbo, cam, etc. IMHO, an SR20DET is a good choice since you get newer EFI tech, you can buy stuff to bolt the stupid thing in, etc. Mod parts and factory service parts are pretty cheap for an SR.

MyLaDyZ Posted November 25, 2009 Author Share Posted November 25, 2009 L28et will pull on a sr20? that sounds good but now i have to find a l28, i was thinking the other day about rebuilding my l24 boring it out and you kno forge rod, pistons, get a good head.

With the appropriate alterations, a ford focus will pull on a corvette. The L is not a focus compared to the SR, however. Start with an L28ET (and not an L24) and save yourself a ton of money.
