grayson260z Posted February 20, 2014 Share Posted February 20, 2014 (edited) I've narrowed my search for an engine to swap into my '74 Datsun to either a Nissan 2.6l Rb26 or a Toyota 3l 2jzgte. Following will be my reasons for each engine and why I want to swap it. (ALL PRICES ARE AS LISTED ON www.jdmenginedepot.com) RB26DET: 1). keep the tradition going of an inline 6, 2.6l as the stock l26 2). More suppport and kits avaliable on the market 3). Very distinct sound of an RB ...(The link to the RB http://www.jdmenginedepot.com/jdm_engine_details/106/Nissan_RB26DETT_Skyline_R32_GT-R_Engine,_Manual_AWD_Trans,_Harness,_&_ECU_JDM_RB26DETT) 2JZGTE: 1). Significantly cheaper than the Rb26 (http://www.jdmenginedepot.com/jdm_engine_details/208/Toyota_2JZ-GTE_VVTI_Aristo_/_Supra_/_Lexus_GS300_/_Lexus_SC300_Engine,_Automatic_Trans_&_Harness_JDM_2JZGTE) 2). Clearance of the turbochargers and the steering column would'nt be a problem 3). C'mon it's a Toyota! 4). I have access to a lot of information on the JZ platform from my friends THE NEGATIVES OF EACH: RB26 1; would have to source an rb25 tranny so 2; Japan only ever made a few cars with the RB26 and not many if not none of them reached the states so parts would be a PITA and wallet 3; Turbos apparently have a lot of issue clearing the steering column on a US spec 260z (LHD) 2JZ: 1; More fabrication work (not really an issue) 2; Less support in the since of swap kits without them costing $2k+ 3; For some reason I feel like wiring would be a pain (I may be wrong) 4; It would come from the shipper with automatic tranny and that just won't do. So I would then have to find either a W series or save up and find an R154. But shouldnt cost any more than the RB26. And someone might acually want a turbo auto trans from a 2j compared to the S**t box that is the AWD RB tranny. For fuel I suppose I'm just gonna go the beaten path of probably a 12-15 gallon fuel cell and a Walbro 255 As you can see I have a lot more positives on the Toyota side compared to the RB but I want input from people WHO HAVE ACTUALLY DONE EITHER SWAP (or have assissted in it, or that know more than it is a hard swap) Thank you guys! - Grayson Edited February 20, 2014 by grayson260z Quote Link to comment Share on other sites More sharing options...
WizardBlack Posted February 20, 2014 Share Posted February 20, 2014 (edited) Well, I'd suspect that your 2JZ engine is less likely to be caned to death by previous owners since it's auto, but no guarantees of course. Service parts for the 2JZ have to be cheaper since it's a USA powerplant. I have my RB essentially swapped, but I could not get a single McKinney mount to work; he sent me three different ones and none worked. I have to fab my own. 2JZ owners can attest but I was under the impression that it was actually a pretty easy swap to physically fit in there. Standalone choices are better on a 2JZ. You can get an AEM and have plenty of ability to swap maps with other 2JZ owners. What are your goals? Walbro isn't going to cut it for either engine with serious goals. Maybe a swirlpot feeding two 044's, etc. IMHO the engines cost a premium for their capability, so I suspect you are planning to go past 400 whp. I would not bother with anything less than an R154. I would go single anyways on the RB to avoid any issues with the steering column. EDIT: I have an RB25 swapped. I used to run a speed shop as a tuner, so I am familiar with both engines previously. I also had a mkiv TT with 6 spd. Edited February 20, 2014 by WizardBlack Quote Link to comment Share on other sites More sharing options...
grayson260z Posted February 20, 2014 Author Share Posted February 20, 2014 Thanks man I appreciate the the reply and the website that has them has a guarantee that their engines don't have over 60k on them so I think it's good there.

EF Ian Posted February 20, 2014 Share Posted February 20, 2014 I'm almost ready to swap in my RB26. I went for it because its a Nissan engine, still 2.6L, it looks better than a 2JZ and I've always loved them Imo a 2JZ would be stronger and less likely to break, they are very well built and tough engines and don't have the problems with he oiling systems that RBs have, they also sound every bit as good as an RB and make great power easily. I was very tempted to go this way. WizardBlack - Don't agree about standalone options, there are plenty for the RB26, only two I am even considering though is the Link G4+ Extreme or a Syvec S6.

78zstyle Posted February 20, 2014 Share Posted February 20, 2014 Looks like you already know what you want. Go with the 2JZ, it just makes sense given what you've stated. Quote Link to comment Share on other sites More sharing options...
Avernier Posted February 21, 2014 Share Posted February 21, 2014 Jz swaps are easy. Wiring and all. And it looks better IMO. Quote Link to comment Share on other sites More sharing options...
grayson260z Posted February 21, 2014 Author Share Posted February 21, 2014 (edited) Another good point is that with an r154 and all it would take to pair it to the engine and convert the car from auto to manual it would probably be close to what it would take to convert the rb to a single Edited February 21, 2014 by grayson260z Quote Link to comment Share on other sites More sharing options...
Avernier Posted February 21, 2014 Share Posted February 21, 2014 Not if you factor in the rb25 trans. Thats expensive. Unless you run a ka trans behind it, which you can do as long as you arent pushing more than 350ish hp. Those are 50$ Quote Link to comment Share on other sites More sharing options...
grayson260z Posted February 21, 2014 Author Share Posted February 21, 2014 Also where have you guys bought engines/transmissions from in the past? Every website that advertises r154s you send yours in and they just rebuild it. Quote Link to comment Share on other sites More sharing options...
grayson260z Posted February 21, 2014 Author Share Posted February 21, 2014 Also in regard to the w58 I fell like for stock twins like 350hp Max it should withstand. I don't plan on drag racing it. Mainly for dding abs the occasional hooning if I see a fine honey you know Quote Link to comment Share on other sites More sharing options...
ZT-R Posted February 22, 2014 Share Posted February 22, 2014 2jz for sure. If i do another one it will be 2j or some sort of v8. RB is nice on sound but thats it. Quote Link to comment Share on other sites More sharing options...
roger280zx Posted February 22, 2014 Share Posted February 22, 2014 Don't you have a hood? Never heard so many suggestions for engine swaps based on how it looks in the engine bay, aside from the 32 ford crowd. Quote Link to comment Share on other sites More sharing options...
johnc Posted February 22, 2014 Share Posted February 22, 2014 Engine choice is purely an emotional thing. Trying to hide that with lists of the pros and cons of each engine is just rationalization. My happiest customers were always the ones who picked an engine based on emotion. Quote Link to comment Share on other sites More sharing options...
Ryan Merrill Posted February 22, 2014 Share Posted February 22, 2014 (edited) Also where have you guys bought engines/transmissions from in the past? Every website that advertises r154s you send yours in and they just rebuild it. Here in Toronto there area lot of import dealers. I bought my Aristo engine and auto tranny for 1500 canadian. I picked up an R154 and flywheel for $800. I picked up a second hand used but new swap kit for 1000 (1500 new) which included motor + tranny mounts plus driveshaft. so $3300 for the driveline and items needed to install. Not bad in my books. On to the wiring next. then install in the summer. There more support and imo more easilt attainable parts for the 2J. I went though the same thing and I ended up going 2JZ Edited February 22, 2014 by Ryan Merrill Quote Link to comment Share on other sites More sharing options...
Wedge Posted February 22, 2014 Share Posted February 22, 2014 Just for your information the shit box awd you speak of has the same internals as the 300zx tt and non turbo and that goes for the rb25 tranny as well they all interchange internally. I agree with you its not a getrag but its a very goodd tranny. As for a choice between the 2 if you live in north america then a 2JZ has WAY MORE support then the RB26. my 2 cents.

Yeah sorry shit box wasn't the appropriate word I just meant in the sense of trying To resell the trans that would come with it not many people are in the market for an rb26 awd trans. I'm more than sure that it is a strong transmission. Quote Link to comment Share on other sites More sharing options...
dapiper Posted October 25, 2014 Share Posted October 25, 2014 I hope this thread continues. I have an L28 N42 custom turbo that just got reincarnated from a bad cam regrind. Nice to get the other one grafted back on. Nevertheless, still tired of the limitations and really want more power, but don't want to invest any more in the old dog. The motor has limitations that can't be easily resolved. The availability of aftermarket parts is non-existent IMHO. Try to source a tube header or intake plenum. Last quote was $3500. Just put the Z32 train and 300ZX TT CV joints in my '77. Got tired of blowing trani's I am preaching to the choir, I know. The 2JZ makes sense or even a 1JZ. I know guys who have the 1J and are making over 400 RWHP and 600 is within reach. I figure, get the 2J and keep the boost below 20 psi and get 550 RWHP easy. Guess I'll find out how much the R200 can stand. Guess we all need another project., but n the end, I just want to drive. Quote Link to comment Share on other sites More sharing options...
grayson260z Posted October 30, 2014 Author Share Posted October 30, 2014 I finally decided a few months ago and bought a 2jzge out of an sc300. Gonna be doing a na-t build on it and trying to net about 350hp just to stay within the safe limits of a w-58 trans Quote Link to comment Share on other sites More sharing options...
JGREEZY Posted November 18, 2014 Share Posted November 18, 2014 I got talked into the same swap. It just makes sense there's plenty of aftermarket & oem support for the 2jz. I pulled the trigger on a 2JZGTE VVTI. I have a shop doing my swap petrolwerks.com in Lindenhurst N.Y. Quote Link to comment Share on other sites More sharing options...
JGREEZY Posted November 18, 2014 Share Posted November 18, 2014 (edited) also check out 2jzswap.com they have what you'll need. he makes a complete wiring kit. Here is another link to some guys doing harneses. www.tweakdperformance.com the guys at the shop use them all the time. they have them already set up, and they're great with the VVTI engine too. Here's the instagram link my car they're info is on their page too and facebook too. http://instagram.com/p/wRnwheyM2B/ Edited December 15, 2014 by JGREEZY Quote Link to comment Share on other sites More sharing options...
