Ioku Posted August 13, 2011 Share Posted August 13, 2011 So I'm trying to figure out what size tires to run on my 88 GL project I will be using a 5 speed D/R trans with the 3.9 final drive but I want to know if you find 31's to be too big with that gearing. I also plan to use a EJ 2.5 franken engine in this car so it will have alot more power over the ae82 1.8. But I still dont want to have to slip the clutch and bog out just taking off from a stop.

Uberoo Posted August 13, 2011 Share Posted August 13, 2011 I've driven a lightweight buggy with 31's it did alright.However, for a normal car bodied subaru with a Ea81/EA82 27" tires is about the max I would go.However, with a 2.5L frankenstein motor it should do just fine.in 1st low at idle it will probably be at 5-10 mph.way too fast to crawl but decent for trail riding.I don't know if you will find any mud capable of bogging the motor down as a plus.should be interesting.Be sure to post of some pics and maybe a video of the thing running..

Scott in Bellingham Posted August 13, 2011 Share Posted August 13, 2011 I run 31s with a ej2.2 Measure out about 30 works great, wouldnt recomend it with the stock 1.8 Quote Link to comment Share on other sites More sharing options...
one eye Posted August 13, 2011 Share Posted August 13, 2011 Ive got and EA81 with a 5speed in an 85 Wagon, and its not going to win any races, but it still tends to go ok, mine mesure out to 30 1/2" Jeff Quote Link to comment Share on other sites More sharing options...
Ioku Posted August 14, 2011 Author Share Posted August 14, 2011 Good to know you don't lose all off roading capabilitys with 31's, I dont, plan on this being a crawler, mainly just to take up the trails and mob through the desert and dunes. I'm going for more of a Dakar rally thing with it, and just think 31's look badass on a Subaru plus the extra clearance and approach will be nice. Once I get some more parts and metal and can really get working on it I'll start a build thread. Quote Link to comment Share on other sites More sharing options...
88Subi4x4 Posted August 15, 2011 Share Posted August 15, 2011 I run 31's on my 91 loyale with a Ej2.2 in it pulls great plenty of power just get a Exedy clutch to handle the extra power! Quote Link to comment Share on other sites More sharing options...
brumby420 Posted August 15, 2011 Share Posted August 15, 2011 I run 31s on my buggy and it gets by alright though it does only weigh around 900 lbs. But with a frankmotor you should have absolutely no problem pushing 31s. Bout the main thing id worry about is how well the DR 5 speed would handle that kind of torque buts thats a different subject.

Uberoo Posted August 22, 2011 Share Posted August 22, 2011 you might be a redneck(or poor) if your tires cost more than the car. Quote Link to comment Share on other sites More sharing options...
