rutts Posted August 2, 2013 Share Posted August 2, 2013 Mazda rotary either n/a or turbo. rally cars use them very effectively and drag motors use them in many disguises. take a look on you tube at escort rotary 13b its fantastic. Quote Link to comment Share on other sites More sharing options...
manta88 Posted August 2, 2013 Share Posted August 2, 2013 Hmmm, that's fast Quote Link to comment Share on other sites More sharing options...
opelmantagsi Posted August 2, 2013 Share Posted August 2, 2013 (edited) Yeah, I would look at going rotary next time, 3 rotor cosmo non turbo. I think a LS1 would be tight, they are tight fit in the holden commodore. Edited August 2, 2013 by opelmantagsi Quote Link to comment Share on other sites More sharing options...
davo Posted August 2, 2013 Share Posted August 2, 2013 I'd like to see a ls1 in there Have thought of it myself in the past over a beer or 3!!! Quote Link to comment Share on other sites More sharing options...
GTREA Posted August 2, 2013 Share Posted August 2, 2013 LS1 was my first choice into a manta, but we have licensing laws here where maximum engine capacity is based on the weight of the car, so in the Mantas case that makes it a maximum capacity of 5100cc (based on 1085kg) So I have had to opt for the 1UZFE LS1 is a lot smaller than the 1UZ Similar weight engines but 270kw stock from LS1 vs 191kw stock from 1UZ. Doesn't really bother me I just want a casual cruiser Quote Link to comment Share on other sites More sharing options...
opelmantagsi Posted August 3, 2013 Share Posted August 3, 2013 (edited) Guy on here in Canada, didn't he test a LS1 in a A series? Yeah x-pat mike Edited August 3, 2013 by opelmantagsi Quote Link to comment Share on other sites More sharing options...
GTREA Posted August 3, 2013 Share Posted August 3, 2013 Yeah I saw that, but dont know why he thought it would not fit?...is the A series bay noticeable smaller? They fit them here in Geminis (Chevette / Kadette)....although not legal for the street here Youtube Link And you can even buy off the shelf engine mounts and modified sump / oil pickups for them Ebay link Quote Link to comment Share on other sites More sharing options...
opelmantagsi Posted August 3, 2013 Share Posted August 3, 2013 Would be an interesting test, looks like it must fit. Just need to worry about the diff. Quote Link to comment Share on other sites More sharing options...
mickappy Posted August 3, 2013 Author Share Posted August 3, 2013 am thinking it will fit with standard sump on. some tunnel and bulk head work tho. you can also get these in 4.8l 300bhp as standard and good for 1200bhp with turbos. which is scary:))) rotary engine looks a great conversion as well. its amazing what you can get out of a 1300cc motor:) Quote Link to comment Share on other sites More sharing options...
GTREA Posted August 3, 2013 Share Posted August 3, 2013 What are your plans for this car? Is it to be road registered, or purely a drag car and setup as such? How quick is quick? LS1s are dirt cheap here so a viable option, not sure how much they in UK 1UZ V8s are cheapish in the UK and with single turbo put out decent power (easy 10s in a Manta) and are getting quite popular for engine transplants. 2jz Toyota straight 6 produce massive reliable power for cheap.

mickappy Posted August 3, 2013 Author Share Posted August 3, 2013 not too bothered about been road registered, I just want the conversion done then upgrade from there.. maybe a supercharger.. turnkey engine can be picked up for less than 2k. gearbox is 1k.

GTREA Posted August 3, 2013 Share Posted August 3, 2013 If you can pick up the LS1's in the UK cheapish then thats the motor to go for I reckon, they are all alloy and quite light, and have great aftermarket support so getting parts or upgrades is easy. Heres a 1000hp blown LS Monaro at a 1000m runway event I raced at recently Whats scary about that? Quote Link to comment Share on other sites More sharing options...
lamchop77 Posted August 3, 2013 Share Posted August 3, 2013 Mate of mine has a 5.0 mustang motor in his mk2 cortina. Was about 375bhp before he put the blower and nitrous on!!! We'll see what it is when it comes back from being set up. Best way to do this conversion is to get hold of a Fox body mustang has the beefy t5 box and 8" rear axle, loads of cheap bit's for these Inc lsd's Quote Link to comment Share on other sites More sharing options...

madmantamik Posted August 7, 2013 Share Posted August 7, 2013 I always fancied the 300zx engine 290 bhp standard trim very light and reliable, the only issue is the 5 speed gearbox is prone to some nasty noises in second gear, but you can get a 6 speed conversion .those crazy japanese get silly power fron these engines. They even have variable exhaust valve timing . Quote Link to comment Share on other sites More sharing options...

611 Posted August 7, 2013 Share Posted August 7, 2013 How about a nice Volvo engine :-) http://www.gowithsolo.com/2010/07/incredible-opel-manta.html Quote Link to comment Share on other sites More sharing options...
GTREA Posted August 8, 2013 Share Posted August 8, 2013 How about a nice Volvo engine :-) http://www.gowithsolo.com/2010/07/incredible-opel-manta.html Nice no doubt, but he will have spent bulk cash on that motor........and for only 570hp. Any number of 2nd hand Jap engines will reliably pump that number out for a fraction of the cost Keep it simple and cheap I reckon...........jap engine or LS1 Quote Link to comment Share on other sites More sharing options...
mickappy Posted August 8, 2013 Author Share Posted August 8, 2013 chevy do a 4.8 lr4 engine. its basically a ls1, theres a few on ebay and there good for lots of power. ls1 engines seen to be hard to find over here... that volve engines awesome.

GTREA Posted August 8, 2013 Share Posted August 8, 2013 (edited) I don't know much about these LR4 engines to be honest but just had a quick read Seem to produce some good numbers powerwise, but the downsides are they are truck based motors (?) and are an Iron block design, so heavy. Maybe look into the Lexus 1UZFE then? Bolt a cheap single turbo to it and even on standard internals you can make some great HP from them, this guys getting 640rwHP on standard internals. VERY popular over here atm for conversions, theres a heap of guys on an Australian forum I am on sticking turbo 1UZ's into everything from 240 Volvo's, Ford Falcon (9.09 qtr), Hilux, Commodores (400rwKW) Silvias and Capri's (8.34 qtr)...and everything but the Capri is a fairly low budget build on standard internals Edited August 8, 2013 by GTREA Quote Link to comment Share on other sites More sharing options...
mickappy Posted August 8, 2013 Author Share Posted August 8, 2013 think its gunna be ls1... I need that sound, just need to find 1 now, plus easy and cheap to tune.. if only I lived in America, going for peanuts over there.. Quote Link to comment Share on other sites More sharing options...
