AndyW Posted September 8, 2010 Report Share Posted September 8, 2010 So I'v got my 87 Raider. Its a work truck so I'm looking for MPG and reliability and keeping up with interstae traffic. I'm looking for oppinions from some you guys with these trucks. I'm getting 16.5mpg right now which is already an improvment over my 11.5 mpg hemi lol. I'm torn bwtween a non intercooled setup or a webber and header with a new 2.25 exhaust with both. The webber and header is an obviously easier job but will it net me better mialage as well as the power? The turbo swap I have everything but the wiring harness to do it but pulling the head to swap the valves and installing oil squirters dosnt have me to excited lol What are some of your oppinions? I'm not going for a power monster, just trying to get out of my own way lol Link to comment Share on other sites More sharing options...
Instaboost Posted September 8, 2010 Report Share Posted September 8, 2010 I think the raider needs better gearing first. Link to comment Share on other sites More sharing options...
scott87star Posted September 9, 2010 Report Share Posted September 9, 2010 Go turbo, power of a bigger motor and mileage of a four cylinder. Scott Link to comment Share on other sites More sharing options...
dmyers151 Posted September 9, 2010 Report Share Posted September 9, 2010 In many cases, a low boost turbo setup will actually yield better mileage. We put a "homemade" turbo setup on my friend's 2000 Eclipse like 6 years ago, his mileage improved by 4-5mpg at 5psi with a DSM 14b. Link to comment Share on other sites More sharing options...
AndyW Posted September 9, 2010 Author Report Share Posted September 9, 2010 In many cases, a low boost turbo setup will actually yield better mileage. We put a "homemade" turbo setup on my friend's 2000 Eclipse like 6 years ago, his mileage improved by 4-5mpg at 5psi with a DSM 14b. Exactly why I was thinking non-intercooled setup with maybe 5-8#. The main thing making me lean towards carb and head is down time, I could do that in an afternoon. Pulling off the topend and rewiring could have me down for a while, and this is my work truck. Although if I'm going to keep it a lowboost fuel injected setup would the oil squirters be a necessity? That could eliminate a bunch of time if those were not mandatory. Also will the NA crank stand up to boost pressure just fine? Link to comment Share on other sites More sharing options...
dmyers151 Posted September 9, 2010 Report Share Posted September 9, 2010 Yeah, I don't think the squirters are necessary. IIRC, the early SQ blocks didn't have them. I think the crank should be fine also, the nitride coating, as I understand, is mainly to prevent scuffing and has less to do with heat related to turbocharging.

Dad Posted September 9, 2010 Report Share Posted September 9, 2010 I'd go for it Andy, only issue would be the higher comp flat top pistons. You have a block here if you need it. the crank should be fine. Even the valves could handle stock boost levels IMHO. Dad Link to comment Share on other sites More sharing options...
AndyW Posted September 9, 2010 Author Report Share Posted September 9, 2010 I was hoping you would chime in Randy. No need for the block, this things runs too nice I just couldnt justify changing motors. You have any wiring harness's around? Link to comment Share on other sites More sharing options...

You have any wiring harness's around? Got an auto parts car- was really considering hanging onto the harness tho- mines kinda hacked. Remember you have flat top pistons in that.

Remember you have flat top pistons in that. Randy What does having the flat tops effect? If I keep the boost level at a stock flatty setup would I be safe? If the flatops will just melt ten that would be my deciding factor for the carb right there. This is a work truck so down time is a factor in tearing into the motor.

Dad Posted September 9, 2010 Report Share Posted September 9, 2010 Try asking Tim C. I think he has a quest with a set of flat tops. Dad Link to comment Share on other sites More sharing options...
swifty Posted February 2, 2011 Report Share Posted February 2, 2011 hello there i have a question. stated above somone said oil squirters are not necessary. my question is i have an older forklift motor that doens have them but is .30 over etc. i plan on going with higher compression and a t3 t4 turbo. do i need them or is it just for the track people. thanks Link to comment Share on other sites More sharing options...
Indiana Posted February 2, 2011 Report Share Posted February 2, 2011 (edited) Flat top pistons and no squirters, a motor that will always run hot. Why is your mileage so sucky? Edited February 2, 2011 by Indiana Link to comment Share on other sites More sharing options...
Komeuppance Posted February 2, 2011 Report Share Posted February 2, 2011 Yeah, I don't think the squirters are necessary. IIRC, the early SQ blocks didn't have them. 83's had squirters... Now I'm second guessing that rebuild on an 83 block we did... pretty sure it had squirters. -Robert Link to comment Share on other sites More sharing options...
Raider 2.6 Posted February 2, 2011 Report Share Posted February 2, 2011 The guys over at 4x4wire will always tell you to go turbo before "modding" a carb'ed 4cyl. Thats how I ended up with a Starion, but I'm still thinking about keeping it together Link to comment Share on other sites More sharing options...
