glad to see this is still up, i remember the debate on teh forums, and how quickly you shit that guy up haha.. this is real machining, fabricating, and engine building. Years later still Great vid
Its obviously his project and a unique one. Why does everyone always toss "wouldn't it be cheaper...." into every argument. Who the hell wants the same old setup that everyone runs when you can run something more unique.
@portland1987 Cheaper, Maybe. More efficient, debatable. More balanced, absolutely not. An RB adds nearly 200 more pounds to the overall weight of the car.
Seriously dude? Slapping and splicing a few KA heads onto the good old L28? AWESOME work. Wish I had your ingenuity, and that setup. I hate having my exhaust and intake on the same side. You've found a great alternative to those ridiculous expensive OS heads
@maluchman1 These cars are useless for drifting. Short narrow wheel base flexy chassis no power steering and no LSD. Where these cars shine is on Motor cross or rally race tracks
that guy is a dumbass, this motor will push 4-450 wrhp- the stock l29 non turbo only pushes like 180-190, and the turbo version only pushes 20-40 more than a stock one- waste of time i think not, a 30% hp increase is far from marginal. furthermore i cant think of anyone else that has pulled of a stroked l28 with dohc tt, can anyone else lol?
This comment has received too many negative votesshow
I personaly give this a zero rating becouse it's a waste of time and you're really not getting that much more horses.their was or still is a Japanese company that produced a DOHC l28 apart from Nissan just becouse Nissan never made a DOHC for the l28.I'll post the info a little bit later.
Correct, years ago.. was called TC24. it was limited and was way to costly. personally i would not mold 3 heads together or 2 even just for 10 hp. But hey these guys did it, and Im glad it worked for them.
This l28dohc was the platform for the rb series engine to come bub.why would you waste so much time molding three heads together hoping youl get it right the first time for only 10-15 extra horses not to productive if you ask any true z owner.
Even That is an understatement! There are far newer lighter more efficient and less complicated Engines out there than that Over teched, Overweight, "Thing" known as the RB26
No, it is not a "whole engine swap". He got two four cylinder heads from another engine, split them apart, machined them and made a DOHC head for the original SOHC engine.
@djelofsocal For that, it's supposed to be a 12 valve head, not 24. Personally i like the 12 valve heads more because the sound they make with triple carbs is unbelievable. :D
Yea buuuuut they will spool very quick, they are only running on 3 cyl each so they need to be small unless you want them spooling at 6000rpm like idiots with supras do. It's not always using the biggest turbo, its using the best size for your engine that yields best performance overall
This conversion isn't... TC24 Heads are impossibly hard to find and really don't gain that much. This head is custom, via three separate KA24DE heads welded/pinned/bolted together...
i'm thinkin one hell of a patent and a small production to make this thing i could build this head with a very indepth print and 3d visual (machinist me) out of aluminum i think you could sell the hell out of this head dude let me know if your interested
lol, to the earlier comments, HE MADE the head from 3 KA24DE heads, the sections are doweled and clamped together... amazing engineering... your pockets would have to go REALLY deep to make him even CONSIDER making another... he said it would cost about 5x what a RB motorset would cost (dont know if he was refering to a RB30?, im from the S-chassis crowd, and the only RB's im familiar with are the R32-34 RB20/25/26)
Outstanding job
