scottieboi94 Posted August 25, 2014 Share Posted August 25, 2014 Is anyone running a gt20 turbo? if so are they better than td04? and is the spool quick? Quote Link to post Share on other sites
Sefton-EP91 Posted August 25, 2014 Share Posted August 25, 2014 Ask Sacha at WEPR. He makes kits for the gt20. I'm sure he will be willing to answer your questions http://www.ukstarletowners.com/topic/84712-gt20-fast-spool-gt-fs-turbo-upgrade-kit/ Quote Link to post Share on other sites
scottieboi94 Posted August 25, 2014 Author Share Posted August 25, 2014 Yes i did mate, he said they spool 600rpm quicker but i just wanted to get opinions from other people running this turbo Im thinking of going for the gt20 kit wepr are selling atm Quote Link to post Share on other sites
Sefton-EP91 Posted August 25, 2014 Share Posted August 25, 2014 There is a video of one that I've seen before is very fast spool up. According to description in link 1bar at 3200rpm and the kit looks awesome!!! Quote Link to post Share on other sites
Gainzy Posted August 25, 2014 Share Posted August 25, 2014 God that is fast spool go for it! Quote Link to post Share on other sites
scottieboi94 Posted August 25, 2014 Author Share Posted August 25, 2014 What sort of rpm would a td04 spool up at 1 bar? Quote Link to post Share on other sites
Ollieh17 Posted August 25, 2014 Share Posted August 25, 2014 3500-4000rpm on most Quote Link to post Share on other sites
scottieboi94 Posted August 25, 2014 Author Share Posted August 25, 2014 Fair enuf, looking a lot like ill be going for the gt20 kit aswell. Another advantage is ill be running a different setup to most people which are usually running td04 Quote Link to post Share on other sites
richglanzav Posted August 25, 2014 Share Posted August 25, 2014 (edited) dont forget a td04 can be picked up for peanuts, a gt20 will no doubt be a lot lot more. theres a reason a td04 is so popular lol. my old car with headwork used to light up all 3 boost lights at a smidge over 3000rpm on a td04.

scottieboi94 Posted August 25, 2014 Author Share Posted August 25, 2014 If i did go for a td04 i wouldnt by standard one, i would want a hybrid one or something for less lag Quote Link to post Share on other sites
Ollieh17 Posted August 25, 2014 Share Posted August 25, 2014 Lag? Do you not know how to change gear ;) tbf if your buying the gt20 kit brand new i would expect the turbo to last a good few years so cost of replacement is low down Quote Link to post Share on other sites
Matt1878 Posted August 25, 2014 Share Posted August 25, 2014 I don't understand why people have an issue with td04?There's hardly any lag at all?Surely you would want it to come on full boost 300rpm later and pull all the way to the redline rather than come on that little earlier and run out off puff? Unless it was just to be used on track with lots of corners or country lanes? Quote Link to post Share on other sites
scottieboi94 Posted August 25, 2014 Author Share Posted August 25, 2014 I just want a gt20 so im running a td04 like everyone else, simple as that lol Quote Link to post Share on other sites
Sefton-EP91 Posted August 25, 2014 Share Posted August 25, 2014 I have to agree with matt1978. I have just ordered the WEPR Billet wheel td04 hybrid kit. I have never been in a td04 starlet EVER but I am willing to sacrifice 300 rpm for it to pull hard to the redline. Don't get me wrong I do love spool on a ct9 but as mentioned. They run out of puff and is very noticeable. Quote Link to post Share on other sites
aidanep71 Posted August 25, 2014 Share Posted August 25, 2014 Anyone have a boost graph for a gt20 on a 4e does it die off on the top end Quote Link to post Share on other sites
Matt1878 Posted August 25, 2014 Share Posted August 25, 2014 Anyone have a boost graph for a gt20 on a 4e does it die off on the top endI'm sure Sacha@ Wepr will have a graph dude. Does a GT20 have the same pull as a TD04 through the midrange? At the same boost pressure I always thought that the TD04 was the best suited stock turbo for a stock 4EFTE as it's not very laggy and will pull hard all the way Quote Link to post Share on other sites
richglanzav Posted August 25, 2014 Share Posted August 25, 2014 fair enough dude u wna be different fair play to ya. p.s - anyone who struggles to keep a td04 on boost on a 4e cant drive lol Quote Link to post Share on other sites

wickedep Posted August 26, 2014 Share Posted August 26, 2014 hey guys..there's no real drop off in power up top (cant believe some of your compared it to the ct9 haha)...the GT20 is only a little smaller than a td04. overall it only makes roughly 20hp less than what a stock td04 is capable of at full tilt. i dont have any graphs..but the gt20 has been in use for years in other similar smaller displacement engine circles (swifts, minis etc and other 1000-1300cc motors) making good power...so its a very capable turbo for anyone looking for less lag. they are also very durable turbos capable of taking a lot of abuse. but obviously not as cheap as a td04 to replace. but being brand new..it should last you a fair few years. 1bar@3200rpm on 4th gear on a 4E. i dont think my GTX35 on my car is laggy lol..so i wonder when people complain about td04 having lag hehe..but everyone's different. if you are really that worried about lag..put the GT20 on a 5e. you'd make similar hp figures to a stock td04 with similar or faster spool up than a ct9. i should have a 5e+GT20 graph soon from a customer who just bolt one of our kits on. while you wait.. http://youtu.be/BXvhvArEfxU sacha Quote Link to post Share on other sites
Matt1878 Posted August 26, 2014 Share Posted August 26, 2014 Awesome Sacha! I'm sure that answers a lot of peoples questions on the GT20/TD04 debate! Quote Link to post Share on other sites
Turbo Goose Posted August 26, 2014 Share Posted August 26, 2014 I opted for a TF035 off a forester as a TD04 alternative. Slightly smaller exhaust housingMade 229bhp at 1.1 bar, full boost at 3.1k rpm Quote Link to post Share on other sites
maddox710 Posted August 26, 2014 Share Posted August 26, 2014 That's awesome Sacha! I can't see why people wouldn't use a gt 20, there's many turbos out there that would possibly work on the little Starlets, what about the borgwarmer k03/04?? Quote Link to post Share on other sites
richardc9052 Posted August 26, 2014 Share Posted August 26, 2014 So basically a gt20 is like a tf035 then Quote Link to post Share on other sites
Turbo Goose Posted August 26, 2014 Share Posted August 26, 2014 (edited) I presume they act like a gt20 but same flanges and fitment as td04 so works with the wide range of td04 kits. Spools faster than a td04 but would say if youre looking for over 230bhp go for td04. I have standard internals so 229bhp with minimal lag suits me Edited August 26, 2014 by Haresign Quote Link to post Share on other sites
turboloon Posted August 26, 2014 Share Posted August 26, 2014 what about a ct12..i'm sure kemnay chris ran one,very little lag and 260bhp(forged),but was ideal for a fast road set up..;) Quote Link to post Share on other sites
