75Super_z Posted June 22, 2009 Share #1 Posted June 22, 2009 Ok, I am hoping for a little help here. I have been searching the website and I have not found a lot of information on this.Im thinking about doing a motor swap to an RB25DET in my 280Z.Question: Has anyone tried modding the L28 Inline 6 (turbo, motor mods, etc) and if so what kind of numbers are you seeing?To swap over to an RB25 its going to be $8k - $10k and Im wondering if I would get some good numbers by just modding up the inline 6?Thanks in advance...- Patrick:beer: Link to comment https://www.classiczcars.com/topic/32307-l28-inline-6-turbod/ Share on other sites More sharing options...
zbane Posted June 22, 2009 Share #2 Posted June 22, 2009 Well, you could always look for an L28ET from an S130 turbo model... Link to comment https://www.classiczcars.com/topic/32307-l28-inline-6-turbod/#findComment-287565 Share on other sites More sharing options...
75Super_z Posted June 22, 2009 Author Share #3 Posted June 22, 2009 That would be a good move but the only prob with that is Im still paying for a swap... Thats what Im trying to avoid. If I have to pay for a swap I will just end up doing the RB25DET.

More importantly, how much power do you really need? What is the car going to be used for? How often will it be driven? and how? Does it need to be a daily driver? What is your budget? Is the rest of the car up to the task of more HP?These are all questions that need answers before any meaningful answer can be given.

Zedyone_kenobi Posted June 22, 2009 Share #5 Posted June 22, 2009 I will say this before you answer anything. A powerful responsive NA engine is a thing of beauty....

75Super_z Posted June 22, 2009 Author Share #6 Posted June 22, 2009 Im looking to be in the 300whp - 350whp (not looking for a TON of power just fun). It is my weekend/summer car. When I do drive it will mostly be to "cruise" but I also want to have enough power to have some fun when I need to. Budget is not that big of a concern.... I am more curious to find out what will be the best option. I can get 350WHP out of the RB25 with just a swap and some bolt ons. Im wondering if I put time and money into the L28 if I will get the same numbers and save some $$ in the process.

Zedyone_kenobi Posted June 22, 2009 Share #7 Posted June 22, 2009 I think that 300 WHP in a Z is a mountain of power. So your looking for around 345 at the crank...wow. Thats huge. But for 8 to 10k you can definitely achieve it. Look into Rebello. They can build you a stroker motor..http://www.rebelloracing.com/enginebuild.htm Link to comment https://www.classiczcars.com/topic/32307-l28-inline-6-turbod/#findComment-287574 Share on other sites More sharing options...
bigoak Posted June 23, 2009 Share #8 Posted June 23, 2009 Go to www.hybridz.org they have done every kind of conceivable swap over there... Link to comment https://www.classiczcars.com/topic/32307-l28-inline-6-turbod/#findComment-287615 Share on other sites More sharing options...
240kconvertible Posted June 23, 2009 Share #9 Posted June 23, 2009 check this out http://cgi.ebay.com.au/Modified-Datsun-240z-with-Engineers-Certificate-NSW_W0QQitemZ250449537353QQcmdZViewItemQQptZAU_Cars?hash=item3a4ff4a949&_trksid=p3286.c0.m14&_trkparms=65%3A1|66%3A2|39%3A1|240%3A1318|301%3A1|293%3A1|294%3A50AS you can see he has gotten 203hp out of the l28 with turbo so if your looking for 300rwhp you might want to go the RB25 route. The RB25DET will add $$'s to the Z as well. Link to comment https://www.classiczcars.com/topic/32307-l28-inline-6-turbod/#findComment-287616 Share on other sites More sharing options...
turbo 260 Posted June 23, 2009 Share #10 Posted June 23, 2009 The easiest thing to do is what I have in my Z. It will be even easier for you because I added 75 fuel injection to my 260. Get a turbo motor with injectors, turbo, exhaust back to cat, and AFM. Swap the injectors off the turbo onto your intake, do a guts swap in the AFM, bolt your intake onto the turbo motor, use the turbo throttle body. I know I'm missing some small stuff, but that the majority of it. In stock form with 10 psi, you will be very happy. Add an intercooler, methanol injection and a bigger turbo with 17 psi and you are at 400 wheel hp.

Jeff G 78 Posted June 23, 2009 Share #11 Posted June 23, 2009 You can make about any amount of power you want out of a turbo L28. Tim Z over on Hybridz is making around 650 to the wheels. It cost big bucks to do it right though. 300 RWHP is doable with little more than junkyard parts if you find the right combination of parts and fuel delivery.

hogie Posted June 23, 2009 Share #12 Posted June 23, 2009 About how much does a rebello engine cost to buy? Aren't they ridiculous high. Link to comment https://www.classiczcars.com/topic/32307-l28-inline-6-turbod/#findComment-287641 Share on other sites More sharing options...
