Hi guys been offered an 90 model MX5 for $1500 (bargain) overall condition isnt overly bad it just ran out of rego in december has 243000km on the clock and im thinking bout building myself a lil drift car to play in :thumbsup:

Seen it done by some guys in QLD and thought id seen that they sold a conversion kit to bolt in the lil lexus V8 in and for the life of me i cant find anything bout it online so 1st of all im wondering if anybody has any info on such a kit? I know it would probably be a big job but i think it would be a great l thing as the 1UFZE is a tough donk and the MX5 has a great lightweight nimble chassis great combination i think. I know a rotor would be easier but thinking the 4L torque would be more fun/reliable plus ive always wanted to put a 1U into something and this popped up cheap and the motors are cheap too.

Soooooooo im looking for opinions on ease of installation and im also looking for somebody with some conversion experience to help me out If you guys think its feasable! I have an engineering workshop and can take care of most of the fabrication side of things just need somebody with the conversion/mechanical side of things :cheers:

So what do you guys think????

Look forward to some input :thanks:

Not a common swap I'm affraid.

If your looking for something V8 I'd be going the LS series. There are quite a few companies in the US that make conversion kits for them.

Look up boss frog and Flyin' Miata.

Hahaha sounds awesome Chris thats what drifting is all about :thumbsup: so its a shitload of work huh? does it really have to have a complete new subframe or was that build overkill so to speak? id honestly like to keep it jap powered though 302 would weigh more than the MX5 itself haha

Wonder how much a LS boat anchor weighs id think it would be alot more than 1UZFE? The guys in the forum who done the conversion bumped the motor back 100mm and almost had 50/50 weight distribution

LS1's are all aluminum why do you think they are such a popular swap in not only "iMiata's" (US market name for the MX-5) but Silvias too?

I think the weights would be very comparable.

google monster miata. that was done YEARS ago.

the bullet has a full subframe under it for a reason. the twist on the chassis will almost fold the car into a pretzel.

suggest doing a bit more reading myself.

also bullets are BLOWN V8s..

Yeah thats true and aftermarket support for the LS is much better than a 1U its just that an LS1 would be far more expensive to buy as well wonder what the conversion kits are worth and to get over here from the states. Wow thats pretty impressive with only 314rwhp!!!!!:worship:

I think u'll find if you weight both of the engines fully dressed, the ls series will be lighter. Those DOHC add alot of weight.

Yeah thats true Ray and the aftermarket support and part prices are much better which makes it look like the only way to go trying to find a W58 or R154 manual box is pretty hard and the fact that a bolt in kit can be purchased makes it more appealing to me as well i crunched some numbersfrom what ive found and i could probably buy the car and get the LS1 into it for about $10000 doing all the work myself :thumbsup:

      Coolant leak?

      Put another overflow bottle (ie, a 1.25 coke bottle or similar) under the overflow hose and see if it is being pushed out there or if it is disappearing into the engine.

      Staring on a stand is no issue. You just have to wire everything up, give it fuel and cross your fingers that the stand is robust enough. Arranging the inlet plumbing is often the hardest part, without any surrounding structure to hand some of it from. No need for coolant if you only want to run it for <1 minute. As to the gearbox - I think the little Aisin box is a bit stronger than the other small Nissan boxes that went behind SRs, but I wouldn't be too keen to test its limits with the torque of a boosted 25. I don't know if you can retain the box and the tailshaft. The box won't connect to the RB without an adapter of some sort, which is either a plate that will push the engine forward (which is not good for fitting it into the bay's available space) or push the box back, which messes with the box position and tailshaft length - OR - cut and shut work on the bellhousing, which is a long way from "least modification". I'd be buying a new 370Z 6 speed or similar, doing what has to be done to that to make it fit RB (ie, cut and shut bellhousing) and the requisite tailshaft custom/mods.

      Hi Everyone I am from West Pennant Hills in NSW. Been too busy until recently to attend to my RB25DET Series 2 engine until recently. I am planning to stick it into the S15 shell at this stage, unless a nice SR20DET turns up... For now, i am going to try and get the RB25 running and working well then decide what gearbox to use. My preference is to retain the SR20DET  6 speed gearbox and tail shaft to retain as much and least modifications as i can avoid. I am an old guy and won't be doing any heavy drifting so i don't need a bullet proof gearbox Does anyone have experience with starting the RB on a stand? I got everything setup as much as I can with the info i can find... endless searching and videos on Youtube I would be great to get some pointers Cheers Songo
