miib14 Posted July 19, 2010 Share Posted July 19, 2010 hi everyone, swapped my corolla throttle body for a starlet turbo one.....has made a HUGE difference... its just so much fun plus its alot louder tooo... would definetly recommend it...got it done by chris..old 1 ..new 1 on car..thanks Quote Link to post Share on other sites
miib14 Posted July 19, 2010 Author Share Posted July 19, 2010 will try and get a video too... Quote Link to post Share on other sites
redz11 Posted July 19, 2010 Share Posted July 19, 2010 I've had this done on mine a while back, it did make a hell of a difference, we have the same inlet manifold Quote Link to post Share on other sites
miib14 Posted July 19, 2010 Author Share Posted July 19, 2010 lol... chris do yours?I've been having so much fun lol.... just floor it and the sound gets louder and louder... lol Quote Link to post Share on other sites
Amjad Posted July 19, 2010 Share Posted July 19, 2010 Guessing you've got the Gen1 4efe inlet mani too then? I was looking to get both done but now I'm thinking Turbo powaaa! Quote Link to post Share on other sites
ryan lang Posted July 19, 2010 Share Posted July 19, 2010 Guessing you've got the Gen1 4efe inlet mani too then? I was looking to get both done but now I'm thinking Turbo powaaa! conversion ftw!! lolwhen you starting yours then dude? Quote Link to post Share on other sites
shorty Posted July 19, 2010 Share Posted July 19, 2010 im porting and polishing a spare tb atm for the V im sure you lads would see an even better gain if you do this befor you fit them just takes time and a dremmel Quote Link to post Share on other sites
Amjad Posted July 19, 2010 Share Posted July 19, 2010 Sorry for the spam miib, Ryan discuss in my build thread if you like; I gotta see what the cash situation is like when I'm at uni, and if I can secure a summer job next year! Quote Link to post Share on other sites
nastyrash 2003 Posted July 19, 2010 Share Posted July 19, 2010 glad you like fella. the under side has the idel valve removed because its water temp operated and causes alot of heat soak in the inlet charge. Quote Link to post Share on other sites
glanza179 Posted July 19, 2010 Share Posted July 19, 2010 how did you get round the TPS been different i have a turbo throttle body sat here but the TPS has a 4 pin plug yet my Glanza S only has a 3 pin plugJim Quote Link to post Share on other sites

enzo_e492901 Posted July 19, 2010 Share Posted July 19, 2010 glad you like fella. the under side has the idel valve removed because its water temp operated and causes alot of heat soak in the inlet charge. Hot coolant runs through the throttle body to stop it icing up in cold weather and is a safety device. The Idle air control valve is electronically controled from the coolant temp sensor via the ECU. Not directly from the temp of the coolant.It does soak heat into the manifold tho but the way to keep the safety device and loose the heat soak is to use an insulator.To anyone thinking of doing this.... This is the redneck way of doing it!I am working on a how-to about modding a Carina E 50mm throttle body to fit the 4E-FE while retaining the idle air control and the power steering idle up valves.Gavin Quote Link to post Share on other sites
Asad Posted July 19, 2010 Share Posted July 19, 2010 Ive by-passed the coolant on the throttle body in my car, it defo feels different not sure if i gained power or notTheres no real problem with icing up tbf unless you live in a snow areacan you elaborate on the safety device? ^ tbh i never knew the ICV is controlled by the CTS Quote Link to post Share on other sites
enzo_e492901 Posted July 19, 2010 Share Posted July 19, 2010 Because of the difference in pressure across the butterfly and the velocity of air flow even warm air can cause freezing and lock the butterfly in whatever posision it is in. (In theory but is it worth the risk?) Coolant runs through the throttle body to stop this so I consider it a safety device.I believe the idle air control valve is controlled as part of the auto choke at idle so uses coolent temp.Gavin Quote Link to post Share on other sites
Guest Enzo Posted July 20, 2010 Share Posted July 20, 2010 imagine the throttle being stuck open at wot then you could see the problem it poses. Quote Link to post Share on other sites
nastyrash 2003 Posted July 20, 2010 Share Posted July 20, 2010 good point but not going to happen, he is running a open air filter coming from under the bonnet, temps get hot under thr. the way i under stand the divce it adds heat to the inlet charge to thin out the air less air less fuel ECO, plus thr are many throttle bodys out thr that do not have heaters take my civic type r,= no heating, but thn not very ECO, also on some intake systems thy do add heat to the air charge at lowwer rpm, reason is thy have large ports and the air does not flow faster nuff to keep the fuel suspended so heat is used to vaperise the fuel, bad thing about this is it adds heat before the camber meaning less heat is taken away from the piston crown. but if you think that will freeze the throttle body check out the CO2 stuff you can get for the intake 1 device cools the air charge by freezing it with a cryo buld and supposed to increase air density by 35% Quote Link to post Share on other sites

miib14 Posted July 25, 2010 Author Share Posted July 25, 2010 got some comparison pics..off the corolla n/aoff the turbo Quote Link to post Share on other sites
lukEp Posted July 25, 2010 Share Posted July 25, 2010 You can clearly see the size difference it's not a little difference it's a lot Quote Link to post Share on other sites
enzo_e492901 Posted July 25, 2010 Share Posted July 25, 2010 To me that "small" throttle body looks smaller than a standard n/a starlet one.My old throttle body. As far as I know its a standard Starlet n/a 4E-FE oneDid the corolla get an even smaller throttle body (than the n/a Starlet) as standard? Because it sure looks like it.Gavin Quote Link to post Share on other sites
lukEp Posted July 25, 2010 Share Posted July 25, 2010 Do you not have the 100bhp gi engine in your starlet? If so it will have the bigger tb Quote Link to post Share on other sites
enzo_e492901 Posted July 25, 2010 Share Posted July 25, 2010 Yeah but to make the Gi engine work we had to use the old small throttle body (the one in photo) because of the different sensors. The Gi one got lost somewhere.After about 4 years I started to think about a bigger one again and I have managed to get a Carina E throttle body (50mm with an 8mm butterfly shaft instead of 10mm and made by a german company for Toyota) and I am machining adaptors for the sensors. Anyway that looks the same size as the "big" one.Gavin Quote Link to post Share on other sites

Kaaaty Posted October 3, 2010 Share Posted October 3, 2010 will this throttle body fit on my bugeye rolla manifold? and what are the gains?? Quote Link to post Share on other sites
lukEp Posted October 3, 2010 Share Posted October 3, 2010 I don't think they do you need a glanza mani to. Quote Link to post Share on other sites
