Z24O Posted April 28, 2006 Share Posted April 28, 2006 hi guys, anyone got any advice on which roots/screw superchargers will fit on an 86-93 302 windsor? it seems you can get the eaton 112 s/c fairly cheaply secondhand with low mileage,few kenne bells and whipple/opcons on e-bay as well but the intake manifold sems to be the stumbling block in most cases...was wondering if anyone's adapted anything to fit any info appreciated regards paul ps not really interested in fitting a centrifugal s/c until i've exhausted other options.....also have EMS capable of running crank angle sensor instead of distributor(as it's in the wrong spot for most of the above options) Quote Link to comment Share on other sites More sharing options...

s3079893 Posted May 1, 2006 Share Posted May 1, 2006 I know a guy running a 400hp 302 clevland with a paxton cetrifugal supercharger, but thats about it. Y dont u want centrifugal? Quote Link to comment Share on other sites More sharing options...
Z24O Posted May 11, 2006 Author Share Posted May 11, 2006 don't want centrifugal because i want off idle instant torque....otherwise might as well use a turbo regards paul "just say no to lag" Quote Link to comment Share on other sites More sharing options...
s3079893 Posted May 11, 2006 Share Posted May 11, 2006 is peak power important, if not you could use a small turbo Quote Link to comment Share on other sites More sharing options...
Z24O Posted May 16, 2006 Author Share Posted May 16, 2006 g'day S30.... after exhausting my search for a blower for a windsor it looks like i will be going twin turbo...probably a couple of r33 skyline turbos off the rb25DET motor...........i am also thinking of LPG so that i can raise the compression ratio to assist with off boost(low rev) torque let me know if you have any input thanks paul Quote Link to comment Share on other sites More sharing options...
s3079893 Posted May 16, 2006 Share Posted May 16, 2006 yeah that seems like a good way to go. Im building a 5L NA windsor and im also planning to go strait gas. I'm thinking of either using an impco 450 carb or a twin throttle boddie gas research carb (but that company is hard to get hold of). Are you planning on running a manual or auto, i hear that manuals have a problem with backfireing which isn't so bad for me because im running normally asperated, but if your running turbos this could cause a problem Quote Link to comment Share on other sites More sharing options...
LMoore56 Posted May 16, 2006 Share Posted May 16, 2006 The Blowzilla, I think is what its called. It will fit the GT-40 EFI lower intake and I think its a twin screw type supercharger. Quote Link to comment Share on other sites More sharing options...
s3079893 Posted May 18, 2006 Share Posted May 18, 2006 Yeah they do look sutible, but for $3000USD you could probably do your twin turbo setup cheaper Quote Link to comment Share on other sites More sharing options...
Z24O Posted May 28, 2006 Author Share Posted May 28, 2006 blowzilla....is that the kenne bell s/c? if so have heard they are good but pricey i have got a twin GRA 400 carbies and twin B2 converters,one of my concerns is if the single gas outlet from the tank will supply enough fuel to support 500hp+ my other dilemma is whether i need to go EMS to manage the timing....i have a spare wolf 3D but was hoping to keep things simple if possible,possibly get the dizzy regraphed? any comments/ideas welcomed paul Quote Link to comment Share on other sites More sharing options...
s3079893 Posted May 28, 2006 Share Posted May 28, 2006 by twin GRA carbies, do u mean gas research? how much do thoes this retail for? Quote Link to comment Share on other sites More sharing options...

s3079893 Posted June 9, 2006 Share Posted June 9, 2006 sounds like you have some awesome cars lying around. my email is s3079893@student.rmit.edu.au . btw a well designed rollcage will probably stiffen the chassis up the best, and does not require an engineering certificate as long as you keep within the requiements they put out.

turbokid Posted June 12, 2006 Share Posted June 12, 2006 i've got 3x240zsilver one's got the boss n/a 302 and celica steel case 5 speed currently..... hello, i was wondering how you bolted the celica trans to the 302? is there a company that makes the proper bell housing? i was looking into the supra r154 trans behind a 302/5.0 injected any info would be great thanks!

Z24O Posted June 12, 2006 Author Share Posted June 12, 2006 hi the guy i got the motor off bought the bellhousing from the states at a cost of $1500!!!,custom HD clutch was another $600,and the box (r154)was new from japan and was $1500 with shifter......the whole lot has done less than 1000km i am selling the lot for $2500 in australia if anyones interested not sure about the celica box/bellhousing,it was in the car when i got it as i mentioned this box has taken some real punishment since mid 80's and still drives like new....a testimony to the strength of toyota gearboxes,the r154 i'd imagine would be even stronger with ratios to suit Z/v8 regards paul hello' date='i was wondering how you bolted the celica trans to the 302? is there a company that makes the proper bell housing? i was looking into the supra r154 trans behind a 302/5.0 injected any info would be great thanks![/quote'] Quote Link to comment Share on other sites More sharing options...
